Management of advanced mandibular osteoradionecrosis with free flap reconstruction.

BACKGROUND: The purpose of this study was to assess the effectiveness of free tissue transfer for treatment of advanced mandibular osteoradionecrosis (ORN) in head and neck cancer patients. METHODS: We reviewed 29 patients who were treated for advanced mandibular ORN by radical resection and reconstruction with free flaps at our institution. All patients had either failed to respond to conservative treatment, including hyperbaric oxygen therapy and debridement or had pathological fracture due to ORN. RESULTS: Twenty-four vascularized bone (17 fibula, five iliac, and two scapula), four rectus abdominis myocutaneous, and one radial forearm fasciocutaneous free flaps were used. The complications occurred in 6 of 29 patients (21%). A total of four flaps (14%) were lost. The mean follow-up was 2 years 9 months. All patients had complete resolution of ORN symptoms. No evidence of ORN recurrence was observed in any patient. CONCLUSION: For advanced osteoradionecrosis of the mandible, radical resection followed by reconstruction using free flap provides a reliable means of obtaining good wound healing with acceptable aesthetic and functional results.

Indications for immediate tissue transfer for soft tissue reconstruction in visceral pelvic surgery.

BACKGROUND: Perineal wound complications may occur after visceral pelvic surgery. We reviewed our experience to determine indications for immediate tissue transfer (TT) to prevent complications. METHODS: Hospital records and computerized data were reviewed on 175 perineal repairs in 156 patients treated at The University of Texas M.D. Anderson Cancer Center for tumors involving the alimentary tract (135 of 175), genitourinary tract (15 of 175), perineum (19 of 175), or sacrum (6 of 175). Patients had either resection of only the colorectum and anus (APR) (46 of 175) or multivisceral resection (MVR) (129 of 175), and the perineal wound was closed by using TT (108 of 175) or primary closure (PC) (67 of 175) on the basis of the surgeon's judgment. Complications were compared between PC and TT groups. RESULTS: Complications occurred in 57% (100 of 175). There was no significant difference overall in PC and TT procedures or in the APR subgroup. There were significantly fewer complications for TT patients in the MVR subgroup (P =.0001). There were significantly fewer complications for TT patients with prior irradiation in both APR (P =.01) and MVR (P =.007) subgroups. CONCLUSIONS: Immediate TT for perineal wound closure is associated with fewer healing complications than PC in a subset of patients with multivisceral resection or prior radiotherapy. Surgical planning in these cases should consider immediate soft tissue reconstruction.

Thrombolytic therapy: what is its role in free flap salvage?

Thrombolytic agents have been demonstrated to improve free flap salvage in animal models. However, clinical evidence regarding their efficacy has been scant. The authors reviewed their experience with flap salvage using thrombolytic therapy in 1,733 free flaps from February 1990 to July 1998. Patients with intraoperative pedicle thrombosis were excluded from this review. Forty-one of the 55 free flaps that were reexplored emergently were identified as having pedicle thrombosis. Of these 41 flaps, 28 free flaps were salvaged (flap salvage group, 68%) and 13 free flaps failed (flap failure group, 32%). Thrombolytic therapy (urokinase in 7 patients, tissue plasminogen activator in 1 patient) was used in six flaps in the flap salvage group and two flaps in the flap failure group. Statistical analysis demonstrated no difference between the two groups with regard to thrombolytic therapy. There was also no difference between the two groups with regard to use of systemic heparin (100-500 U per hour) at the time of pedicle thrombosis or with regard to whether Fogarty catheters were used. Smoking, preoperative radiotherapy, and the use of interpositional vein grafts during initial flap reconstruction had no impact on the outcome of flap salvage. The flap salvage group was reexplored at a mean of 1.5 days compared with the flap failure group, which was reexplored at a mean of 4.2 days (p = 0.007). Early detection of pedicle thrombosis remains the most important factor in the salvage of free flaps. Although these numbers are small and definitive statements cannot be made, the role of thrombolytic agents in free flap salvage requires further clinical evaluation.

Postoperative morphine requirements of free TRAM and DIEP flaps.

In a review of the charts of 158 patients who had undergone breast reconstruction with free transverse rectus abdominis musculocutaneous (TRAM) or deep inferior epigastric perforator (DIEP) flaps and who were treated for postoperative pain with morphine administered by a patient-controlled analgesia pump, the total dose of morphine administered during hospitalization for the flap transfer was measured. Patients whose treatment was supplemented by other intravenous narcotics were excluded from the study. The mean amount of morphine per kilogram required by patients who had reconstruction with DIEP flaps (0.74 mg/kg, n = 26) was found to be significantly less than the amount required by patients who had reconstruction with TRAM flaps (1.65 mg/kg; n = 132; p < 0.001). DIEP flap patients also remained in the hospital less time (mean, 4.73 days) than did free TRAM flap patients (mean, 5.21 days; p = 0.026), but the difference was less than one full hospital day. It was concluded that the use of the DIEP flap does reduce the patient requirement for postoperative pain medication and therefore presumably reduces postoperative pain. It may also slightly shorten hospital stay.

Incidence of hematoma associated with ketorolac after TRAM flap breast reconstruction.

Ketorolac is frequently used as an adjunct for postoperative pain relief, especially by anesthesiologists during the immediate postoperative period. It can be used alone as an analgesic but is more often used to potentiate the actions of narcotics such as morphine or meperidine in an attempt to reduce the total dose and side effects of those drugs. The manufacturer of ketorolac cautions against its use in patients who have a high risk of postoperative bleeding, for fear of increasing the risk of hematoma, but the risk in transverse rectus abdominis musculocutaneous (TRAM) flap patients has never been reported. In a study of 215 patients who had undergone TRAM flap breast reconstruction, it was determined that patients who received intravenous ketorolac (n = 65) as an adjunct to their treatment with morphine administered by use of a patient-controlled analgesia device required less morphine (mean cumulative dose, 1.39 mg/kg) than did patients who did not receive ketorolac (n = 150; mean cumulative dose, 1.75 mg/kg; p = 0.02). There was no increase in the incidence of hematoma in patients who were treated with ketorolac. The data presented in this study suggest that the use of intravenous ketorolac does reduce the need for narcotics administration in patients undergoing TRAM flap breast reconstruction, without significantly increasing the risk of hematoma.

Comparison of cost for DIEP and free TRAM flap breast reconstructions.

A recent article by Kaplan and Allen suggested that deep inferior epigastric perforator (DIEP) flap breast reconstruction was less expensive than reconstruction performed with free transverse rectus abdominis musculocutaneous (TRAM) flaps. To test that hypothesis, a series of patients who had undergone unilateral breast-mound reconstruction by the first author using DIEP or free TRAM flaps between November 1, 1996, and March 30, 2000, were reviewed. Bilateral reconstructions and reconstructions performed by other surgeons in the department were excluded to eliminate all variables except the choice of flap. All hours in the operating room and days in the hospital until discharge were included. Early readmissions for the treatment of complications were included, as were the costs of the mastectomy in the case of immediate reconstructions, but late revisions and nipple reconstructions were not. The totals were then converted into resource costs in 1999 dollars, and the DIEP and free TRAM flap groups compared. There were 21 DIEP flaps and 24 free TRAM flaps in the series. In this series, there was no significant difference between the cost of DIEP and free TRAM flap breast reconstruction.

Comparison of immediate and delayed free TRAM flap breast reconstruction in patients receiving postmastectomy radiation therapy.

Tumor pathologic features and the extent of nodal involvement dictate whether radiation therapy is given after mastectomy for breast cancer. It is generally well accepted that radiation negatively influences the outcome of implant-based breast reconstruction. However, the long-term effect of radiation therapy on the outcome of breast reconstruction with the free transverse rectus abdominis myocutaneous (TRAM) flap is still unclear. For patients who need postmastectomy radiation therapy, the optimal timing of TRAM flap reconstruction is controversial. This study compares the outcome of immediate and delayed free TRAM flap breast reconstruction in patients who received postmastectomy radiation therapy. All patients at The University of Texas M. D. Anderson Cancer Center who received postmastectomy radiation therapy and who also underwent free TRAM flap breast reconstruction between January of 1988 and December of 1998 were included in the study. Patients who received radiation therapy before delayed TRAM flap reconstruction were compared with patients who underwent immediate TRAM flap reconstruction before radiation therapy. Early and late complications were compared between the two groups. Early complications included vessel thrombosis, partial or total flap loss, mastectomy skin flap necrosis, and local wound-healing problems, whereas late complications included fat necrosis, volume loss, and flap contracture of free TRAM breast mounds. Late complications were evaluated at least 1 year after the completion of radiation therapy for patients who had delayed reconstruction and at least 1 year after reconstruction for patients who had immediate reconstruction. During the study period, 32 patients had immediate TRAM flap reconstruction before radiation therapy and 70 patients had radiation therapy before TRAM flap reconstruction. Mean follow-up times for the immediate reconstruction and delayed reconstruction groups were 3 and 5 years, respectively. The mean radiation dose was 50 Gy in the immediate reconstruction group and 51 Gy in the delayed reconstruction group. One complete flap loss occurred in the delayed reconstruction group, and no flap loss occurred in the immediate reconstruction group. The incidence of early complications did not differ significantly between the two groups. However, the incidence of late complications was significantly higher in the immediate reconstruction group than in the delayed reconstruction group (87.5 percent versus 8.6 percent; p = 0.000). Nine patients (28 percent) in the immediate reconstruction group required an additional flap to correct the distorted contour from flap shrinkage and severe flap contraction. These findings indicate that, in patients who are candidates for free TRAM flap breast reconstruction and need postmastectomy radiation therapy, reconstruction should be delayed until radiation therapy is complete.

Reconstructive management of contralateral breast cancer in patients who previously underwent unilateral breast reconstruction.

When a patient who has had unilateral breast reconstruction presents with a new cancer on the opposite side, the reconstructive management of the second breast can be unclear. This study was performed to determine whether reconstruction of the second breast is oncologically reasonable and to evaluate the reconstructive options available to these patients. Patients who had mastectomy with unilateral breast reconstruction between 1988 and 1994 and who had a minimal follow-up of 5 years from the initial breast cancer were reviewed. Of 469 patients reviewed, 18 patients (4 percent) were identified who developed contralateral breast cancer. Mean age at the initial breast cancer presentation was 43 years (range, 26 to 57 years), and mean age at presentation with contralateral breast cancer was 48 years (range, 36 to 67). The mean interval between the initial and contralateral breast cancer presentations was 5 years (range, 1 to 10 years). Mean follow-up from the time of contralateral breast cancer was 5 years (range, 1 to 9 years). In most cases, contralateral breast cancer presented at an early stage (13 of 18 patients; 72 percent), and a shift to an earlier stage at presentation of the contralateral cancer was evident compared with the initial breast cancer. Of the 18 patients who developed contralateral breast cancer, 16 (89 percent) had no evidence of disease, one was alive with disease, and one died. Reconstructive management after the initial mastectomy included 16 transverse rectus abdominis myocutaneous flaps (seven free and nine pedicled), one latissimus dorsi myocutaneous flap with implant, and one superior gluteal free flap. Surgical management of the second breast after contralateral breast cancer included breast conservation in two patients, mastectomy without reconstruction in four, and mastectomy with reconstruction in 12. Reconstruction of the second breast included one free transverse rectus abdominis myocutaneous flap, three extended latissimus dorsi flaps, two latissimus dorsi myocutaneous flaps with implants, three implants alone, two Rubens flaps, and one superior gluteal free flap. No major complications were noted after the reconstruction of the second breast. The best symmetry was obtained when similar methods and tissues were used on both sides. The incidence of contralateral breast cancer after mastectomy and unilateral breast reconstruction is low. In most cases, contralateral breast cancer presents at an earlier stage compared with the initial breast cancer, and the prognosis is good. In patients who develop a contralateral breast cancer after mastectomy and unilateral breast reconstruction, the reconstruction of the second breast after mastectomy is oncologically reasonable and should be offered to provide optimal breast symmetry and a better quality of life. The best result is obtained when similar methods and tissues are used on both sides.

Coverage of skull base defects.

Successful reconstruction of the cranial base requires a knowledge of this complex anatomic area, a careful assessment of the defect, a healthy respect for the potential for ascending infection and meningitis, and reliable techniques to effectively contain the intracranial space with vascularized tissue. The first step in reconstruction is a secure dural repair, which must be covered by a healthy vascularized layer. The scalp contains galeal and pericranial flaps, which are usually incorporated into the reconstruction. Sometimes, along with local muscles such as the temporalis, these local tissues are all that is needed to complete the reconstruction. When the defects are larger and in irradiated beds, free tissue transfer has emerged as the most reliable method to bolster the dural repair.

Recent advances in reconstructive surgery for soft-tissue sarcomas.

The size and complexity of wounds following soft-tissue sarcoma resection have increased over the years. Many advances have been made in reconstructive surgery during the past 30 years. These advances have occurred because of refined knowledge of muscle, skin, and fascial blood flow and through the development of free tissue transfer techniques. In this review, current methods of reconstruction following sarcoma resection are discussed, and advances are highlighted.

Free filet extremity flap: indications and options for reconstruction.

Radical and extended forequarter and hind limb amputations have been used for curative and palliative intents. Concerns regarding wound healing and closure, especially in irradiated fields, have occasionally limited the extent of ablation. This article reports an experience with coverage of these large defects by using the free filet extremity flap. A retrospective review was performed of 11 patients who had undergone immediate reconstruction with free filet extremity flaps between 1991 and 1998. There were nine men and two women with an average age of 43.9 years. All except three patients received preoperative radiotherapy. Resections included four hindquarter and seven forequarter amputations for palliation of intractable pain, tissue necrosis, and infections. Donor vessels included the brachial artery, its venae comitantes, cephalic and basilic veins, and common femoral and popliteal vessels. Immediate reconstruction was successful in all cases by the use of the amputated limb as the free filet flap. All wounds healed despite irradiation inclusive of defects up to 50 cm x 70 cm (3500 cm2). The average follow-up time was 5 months with a mean survival of 3.5 months. Four patients currently are alive, and one patient died within 30 days of surgery. The remaining six patients have died of their disease within 9 months of the palliative procedures. Pain, tissue necrosis, and infections were improved in all patients after hospital discharge. Extensive defects can be reconstructed and healed successfully, even in irradiated wounds, with the use of the free filet extremity flap. Appropriate advanced preoperative and intraoperative planning is essential. Although survival was unchanged, this technique allowed healed wounds with an improvement in the quality of life.

Effect of obesity on flap and donor-site complications in free transverse rectus abdominis myocutaneous flap breast reconstruction.

The purpose of this study was to assess the effect of obesity on flap and donor-site complications in patients undergoing free transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction. All patients undergoing breast reconstruction with free TRAM flaps at our institution from February 1, 1989, through May 31, 1998, were reviewed. Patients were divided into three groups based on their body mass index: normal (body mass index <25), overweight (body mass index 25 to 29), obese (body mass index > or =30). Flap and donor-site complications in the three groups were compared. A total of 936 breast reconstructions with free TRAM flaps were performed in 718 patients. There were 442 (61.6 percent) normal-weight, 212 (29.5 percent) overweight, and 64 (8.9 percent) obese patients. Flap complications occurred in 222 of 936 flaps (23.7 percent). Compared with normal-weight patients, obese patients had a significantly higher rate of overall flap complications (39.1 versus 20.4 percent; p = 0.001), total flap loss (3.2 versus 0 percent; p = 0.001), flap seroma (10.9 versus 3.2 percent; p = 0.004), and mastectomy flap necrosis (21.9 versus 6.6 percent; p = 0.001). Similarly, overweight patients had a significantly higher rate of overall flap complications (27.8 versus 20.4 percent; p = 0.033), total flap loss (1.9 versus 0 percent p = 0.004), flap hematoma (0 versus 3.2 percent; p = 0.007), and mastectomy flap necrosis (15.1 versus 6.6 percent; p = 0.001) compared with normal-weight patients. Donor-site complications occurred in 106 of 718 patients (14.8 percent). Compared with normal-weight patients, obese patients had a significantly higher rate of overall donor-site complications (23.4 versus 11.1 percent; p = 0.005), infection (4.7 versus 0.5 percent; p = 0.016), seroma (9.4 versus 0.9 percent; p <0.001), and hernia (6.3 versus 1.6 percent; p = 0.039). Similarly, overweight patients had a significantly higher rate of overall donor-site complications (19.8 versus 11.1 percent; p = 0.003), infection (2.4 versus 0.5 percent; p = 0.039), bulge (5.2 versus 1.8 percent; p = 0.016), and hernia (4.3 versus 1.6 percent; p = 0.039) compared with normal-weight patients. There were no significant differences in age distribution, smoking history, or comorbid conditions among the three groups of patients. Obese patients, however, had a significantly higher incidence of preoperative radiotherapy and preoperative chemotherapy than did patients in the other two groups. A total of 23.4 percent of obese patients had preoperative radiation therapy compared with 12.3 percent of overweight patients and 12.4 percent of normal-weight patients; 34.4 percent of obese patients had preoperative chemotherapy compared with 24.5 percent of overweight patients and 17.7 percent of normal-weight patients. Multiple logistic regression analysis was used to determine the risk factors for flap and donor-site complications while simultaneously controlling for potential confounding factors, including the incidence of preoperative chemotherapy and radiotherapy. In summary, obese and overweight patients undergoing breast reconstruction with free TRAM flaps had significantly higher total flap loss, flap hematoma, flap seroma, mastectomy skin flap necrosis, donor-site infection, donor-site seroma, and hernia compared with normal-weight patients. There were no significant differences in the rate of partial flap loss, vessel thrombosis, fat necrosis, abdominal flap necrosis, or umbilical necrosis between any of the groups. The majority of overweight and even obese patients who undertake breast reconstruction with free TRAM flaps complete the reconstruction successfully. Both such patients and surgeons, however, must clearly understand that the risk of failure and complications is higher than in normal-weight patients. Patients who are morbidly obese are at very high risk of failure and complications and should avoid any type of TRAM flap breast reconstruction.

Closure of hemicorporectomy with bilateral subtotal thigh flaps.

Hemicorporectomy is typically performed with a circumferential truncal incision, and the wound is closed primarily. Wound disruption is a common complication, especially at the base of the wound closure and posteriorly at the lumbar vertebral level. We report a case of the use of bilateral subtotal thigh flaps for the closure of a hemicorporectomy wound in a patient with a defect extending up to the high lumbar region. The subtotal thigh flap is a well-vascularized thick flap that provides a firm support for the abdominal viscera and is a large flap that can be used to close even a high lumbar defect.

Effect of smoking on complications in patients undergoing free TRAM flap breast reconstruction.

Free pedicled transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction is often advocated as the procedure of choice for autogenous tissue breast reconstruction in high-risk patients, such as smokers. However, whether use of the free TRAM flap is a desirable option for breast reconstruction in smokers is still unclear. All patients undergoing breast reconstruction with free TRAM flaps at our institution between February of 1989 and May of 1998 were reviewed. Patients were classified as smokers, former smokers (patients who had stopped smoking at least 4 weeks before surgery), and nonsmokers. Flap and donor-site complications in the three groups were compared. Information on demographic characteristics, body mass index, and comorbid medical conditions was used to perform multivariate statistical analysis. A total of 936 breast reconstructions with free TRAM flaps were performed in 718 patients (80.9 percent immediate; 23.3 percent bilateral). There were 478 nonsmokers, 150 former smokers, and 90 smokers. Flap complications occurred in 222 (23.7 percent) of 936 flaps. Smokers had a higher incidence of mastectomy flap necrosis than nonsmokers (18.9 percent versus 9.0 percent; p = 0.005). Smokers who underwent immediate reconstruction had a significantly higher incidence of mastectomy skin flap necrosis than did smokers who underwent delayed reconstruction (21.7 percent versus 0 percent; p = 0.039). Donor-site complications occurred in 106 (14.8 percent) of 718 patients. Donor-site complications were more common in smokers than in former smokers (25.6 percent versus 10.0 percent; p = 0.001) or nonsmokers (25.6 percent versus 14.2 percent; p = 0.007). Compared with nonsmokers, smokers had significantly higher rates of abdominal flap necrosis (4.4 percent versus 0.8 percent; p = 0.025) and hernia (6.7 percent versus 2.1 percent; p = 0.016). No significant difference in complication rates was noted between former smokers and nonsmokers. Among smokers, patients with a smoking history of greater than 10 pack-years had a significantly higher overall complication rate compared with patients with a smoking history of 10 or fewer pack-years (55.8 percent versus 23.8 percent; p = 0.049). In summary, free TRAM flap breast reconstruction in smokers was not associated with a significant increase in the rates of vessel thrombosis, flap loss, or fat necrosis compared with rates in nonsmokers. However, smokers were at significantly higher risk for mastectomy skin flap necrosis, abdominal flap necrosis, and hernia compared with nonsmokers. Patients with a smoking history of greater than 10 pack-years were at especially high risk for perioperative complications, suggesting that this should be considered a relative contraindication for free TRAM flap breast reconstruction. Smoking-related complications were significantly reduced when the reconstruction was delayed or when the patient stopped smoking at least 4 weeks before surgery.

Reconstruction of large sacral defects following total sacrectomy.

Total sacrectomies for cancer ablation often result in extensive defects that are challenging to reconstruct. In an effort to elucidate the criteria to select the most effective reconstructive options, we reviewed our experience with the management of large sacral wound defects. All patients who had a sacral defect reconstruction after a total sacrectomy at our institution between January of 1993 and August of 1998 were reviewed. The size of the defect, the type of reconstruction, postoperative complications, and functional outcome in each patient were assessed. A total of 27 flaps were performed in 25 patients for sacral defect reconstruction after a total sacrectomy. Diagnoses consisted of chordoma (n = 13), giant cell carcinoma (n = 2), sarcoma (n = 5), rectal adenocarcinoma (n = 4), and radiation induced necrosis (n = 1). The size of sacral defects ranged from 18 to 450 cm2 (mean, 189.8 cm2). Ten patients, including five who had preoperative radiation therapy, underwent transpelvic vertical rectus abdominis myocutaneous (VRAM) flap reconstruction for sacral defects with a mean size of 203.3 cm2. Of these, five patients (50 percent) had complications (four minor wound dehiscences and one seroma). Eight patients, including one who had preoperative radiation therapy, underwent bilateral gluteal advancement flap reconstruction for sacral defects with a mean size of 198.0 cm2. They had no complications. Two patients, both of whom had preoperative radiation therapy, underwent gluteal rotation flap reconstruction for sacral defects of 120 cm2 and 144 cm2. Both patients had complications (one partial flap loss and one nonhealing wound requiring a free flap). Three patients, including one who had preoperative radiation therapy, underwent reconstruction with combined gluteal and posterior thigh flaps for sacral defects with a mean size of 246 cm2; two of these patients had partial necrosis of the posterior thigh flaps. Three patients, all of whom had preoperative radiation therapy, underwent free flap reconstruction for sacral defects with a mean size of 144.3 cm2. They had no complications. Our experience suggests that there are three reliable options for the reconstruction of large sacral wound defects: bilateral gluteal advancement flaps, transpelvic rectus myocutaneous flaps, and free flaps. In patients with no preoperative radiation therapy and intact gluteal vessels, the use of bilateral gluteal advancement flaps should be considered. In patients with a history of radiation to the sacral area and in patients whose gluteal vessels have been damaged, the use of the transpelvic VRAM flap should be considered. If the transpelvic VRAM flap cannot be used because of previous abdominal surgery, a free flap should be considered as a last option.

Postoperative adjuvant irradiation: effects on tranverse rectus abdominis muscle flap breast reconstruction.

The use of postoperative irradiation following oncologic breast surgery is dictated by tumor pathology, margins, and lymph node involvement. Although irradiation negatively influences implant reconstruction, it is less clear what effect it has on autogenous tissue. This study evaluated the effect of postoperative irradiation on transverse rectus abdominis muscle (TRAM) flap breast reconstruction. A retrospective review was performed on all patients undergoing immediate TRAM flap breast reconstruction followed by postoperative irradiation between 1988 and 1998. Forty-one patients with a median age of 48 years received an average of 50.99 Gy of fractionated irradiation within 6 months after breast reconstruction. All except two received adjuvant chemotherapy. Data were obtained from personal communication, physical examination, chart, and photographic review. The minimum follow-up time was 1 year, with an average of 3 years, after completion of radiation therapy. Nine patients received pedicled TRAM flaps and 32 received reconstruction with microvascular transfer. Fourteen patients had bilateral reconstruction, but irradiation was administered unilaterally to the breast with the higher risk of local recurrence. The remaining 27 patients had unilateral reconstruction. All patients were examined at least 1 year after radiotherapy. No flap loss occurred, but 10 patients (24 percent) required an additional flap to correct flap contracture. Nine patients (22 percent) maintained a normal breast volume. Hyperpigmentation occurred in 37 percent of the patients, and 56 percent were noted to have a firm reconstruction. Palpable fat necrosis was noted in 34 percent of the flaps and loss of symmetry in 78 percent. Because the numbers were small, there was no statistical difference between the pedicled and free TRAM group. However, as a group, the findings were statistically significant when compared with 1,443 nonirradiated TRAM patients. Despite the success of flap transfer, unpredictable volume, contour, and symmetry loss make it difficult to achieve consistent results using immediate TRAM breast reconstruction with postoperative irradiation. TRAM flap reconstruction in this setting should be approached cautiously, and delayed reconstruction in selected patients should be considered. Patients should be aware that multiple revisions and, possibly, additional flaps are necessary to correct the progressive deformity from radiation therapy.
