A minimal transverse incision with low median sternotomy for pediatric congenital heart surgery.

OBJECTIVES: Median sternotomy is the incision of choice for most cardiac surgical procedures, but the full-length vertical skin incision generally leaves an unsightly scar. In certain patients undergoing short, low-risk procedures, cosmetic considerations are of relatively greater importance. METHODS: A minimal transverse curvilinear skin incision with low median sternotomy is described which gives adequate exposure for selected open-heart procedures. Since September 1997, this approach has been used in 22 pediatric patients undergoing open-heart surgery including five cases of Fallot's tetralogy. We also compared the operation time and result with other approaches. RESULTS: Using this modified method, the exposure of the heart was good enough, and there were no difficulties in cannulating the ascending aorta for cardiopulmonary bypass. Although it took a longer time to close the wound, the operation time was similar to the standard approach. The small transverse wound was not visible under conventional clothes. CONCLUSIONS: A minimal transverse incision with low median sternotomy provides an alternative approach for small wound open-heart surgery in patients with a simple congenital cardiac defect. It is technically feasible and has a good cosmetic result.

Single vessel revascularization with beating heart techniques -- minithoracotomy or sternotomy?

OBJECTIVE: The purpose of the study was to evaluate the best surgical approach in off-pump single vessel revascularization of the left anterior descending coronary artery (LAD). METHODS: In 256 patients a single left internal mammary artery (LIMA) to LAD bypass was performed with beating heart techniques through a left anterior minithoracotomy (minimally invasive direct coronary artery bypass (MIDCAB), n=129) or a full sternotomy (off-pump coronary artery bypass (OPCAB), n=127). RESULTS: In the OPCAB group, significantly more severe comorbidities (P=0.001) and redo-operations were noted (P<0.001). Conversion to sternotomy or CPB was necessary in five MIDCAB patients and one OPCAB patient. No cerebrovascular accident was seen in both groups. There was no hospital death in MIDCAB- and two deaths in OPCAB procedures (P=ns). There was a significant reduction in time of surgery (P=0.028) and coronary occlusion (P=0.009) in the OPCAB group. No differences in postoperative ventilation time, ICU stay and length of hospital stay were recorded between groups. Wound infections occurred in six MIDCAB patients (4.7%) and one OPCAB patient (0.8%). Early postoperative reoperation due to graft failure was necessary in three patients after MIDCAB and two patients after OPCAB (P=ns). Confirmed by angiography, the early graft patency rate was 96 and 98%, respectively (P=ns). CONCLUSIONS: Both beating heart techniques showed good results with low hospital mortality, low early complications and comparable angiographic results. Nevertheless, MIDCAB is a challenging technique as demonstrated by the longer times of surgery and coronary occlusion with a tendency towards a higher risk of conversion and wound infection. Thus, this technique should only be performed in selected patients with favourable coronary anatomy. Through a sternotomy approach, single vessel revascularization can be performed safely off-pump even in high-risk patients.

A new approach to cardiac valve replacement through a small midline incision and inverted L shape partial sternotomy.

OBJECTIVE: Minimally invasive cardiac surgery is becoming more popular as an alternative technique in some cardiac operations. We report our experience with an inverted 'L' ministernotomy in 25 patients and describe the technical details of this new approach. METHODS: From June 1996 to February 1997 we performed 25 ministernotomy approaches for cardiac surgery, 17 aortic and 7 mitral valve replacements and 1 atrial septal defect closure. A comparison group included all patients (n = 126) operated on for mitral or aortic valve replacement through a median sternotomy since June 1996. RESULTS: Ventilatory support, Intensive Care Unit stay and hospital stay were 8.3 h (SD = 4 h), 25 h (SD = 8 h) and 5.5 days (SD = 3 days) in the L ministernotomy group and 11.5 h (SD = 5), 53 h (SD = 11) and 9.1 days (SD = 4 days) in the median sternotomy group (P < 0 05). Mortality and morbidity are similar to conventional sternotomy (hospital mortality 4% vs. 5.5%; P not significant). CONCLUSIONS: We conclude that inverted L ministernotomy for cardiac surgery is a safe approach and can offer some advantages over the conventional approach.

Clamshell or sternotomy for double lung or heart-lung transplantation?

OBJECTIVE: To evaluate the influence of either incision on the lungs and chest wall. METHODS: Ninety-two double lung (DLT) or heart-lung (HLT) transplantations were done since January 1990. There were 22 (24%) hospital deaths, leaving 70 patients with complete data for evaluation. We did 38 DLT and 32 HLT for end-stage chronic respiratory failure (n = 22) and primary (n = 34) or secondary (n = 14) pulmonary hypertension, using 37 fourth or fifth interspace clamshell incisions and 33 median sternotomies. RESULTS: The clamshell group included a higher percentage of DLTs (73 vs. 33%, P = 0.001) but recipient age, gender, preoperative diagnosis, bronchial anastomotic complications, number of cytomegalovirus infection, episode of acute rejection per patient-months and incidence of bronchiolitis obliterans were not statistically different between the two groups. At a follow-up time of 3.7 +/- 2 years, the overall 5-year survival of 57% was not influenced by the type of incision. The clamshell incision caused sternal over-riding in 12 (32%) patients, and eight surgical clamshell revision were necessary as compared with one median sternotomy (P = 0.02). The clamshell incision was associated with a significantly higher incidence of postoperative chronic pain (27 vs. 6%, P = 0.02). Postoperative mechanical properties of the chest wall were significantly (P < 0.0001) worse in the clamshell-group patients while the intrinsic properties of the airways were not different. CONCLUSIONS: The clamshell incision results in more postoperative deformity, chronic pain, and impaired function as compared with median sternotomy. A bilateral anterolateral thoracotomy without division of the sternum is proposed for the sequential bilateral lung transplantation technique.

Minimally invasive mitral valve surgery: mini-sternotomy with extended transseptal approach.

A partial upper sternotomy and an extended transseptal incision provide excellent exposure for mitral valve surgery. From March 1997 to December 1998, 462 patients had mitral valve surgeries using this minimally invasive approach. Eighty-seven percent had mitral valve repair, and 13% had mitral valve replacement. Thirteen patients (3%) required conversion to full sternotomy, and all other patients had the procedure completed using the initial approach. Forty-eight percent of patients were extubated within 6 hours of surgery, and 47% of patients spent less than 24 hours in the intensive care unit (ICU). Mean hospital length of stay was 7.2 +/- 5.4 days. Eighty-six percent of patients received no blood products. There was 1 hospital death (0.2%). Morbidity included reexploration for bleeding (4%), respiratory insufficiency (1%), stroke (1%), myocardial infarction (0.2%), and wound infection (0.2%). We conclude that virtually all mitral valve procedures, including complicated repairs, can be accomplished via partial upper sternotomy with an extended transseptal incision. This approach provides excellent exposure of the mitral valve and results in a low rate of wound complications, low transfusion requirements, and excellent cosmesis.

Evaluation of the electroencephalographic bispectral index during fentanyl-midazolam anaesthesia for cardiac surgery. Does it predict haemodynamic responses during endotracheal intubation and sternotomy?

The bispectral index, a value derived from the electroencephalogram, has been proposed as a measure of anaesthetic effect. The aim of the present study was to evaluate the bispectral index during midazolam-fentanyl anaesthesia for cardiac surgery for its possible role as a predictor of increases in systolic blood pressure during endotracheal intubation and sternotomy. After institutional approval 15 consenting patients, scheduled for elective cardiac surgery, were selected for the study. Anaesthesia was induced in all patients with a loading dose of fentanyl 7.5-10 micrograms kg-1, midazolam 0.15 mg kg-1 and pancuronium 0.1 mg kg-1. After a further bolus dose of fentanyl 10-12.5 micrograms kg-1 prior to the start of incision and sternotomy, maintenance infusion rates of fentanyl 4-6 micrograms kg-1 h-1 and midazolam 0.1 mg kg-1 h-1 were started and continued through surgery at the discretion of the anaesthetist and guided by the presenting clinical and haemodynamic responses. The control of anaesthesia was never based on the value of the bispectral index. The mean bispectral index value decreased from 95.7 (3.1) at base-line to 59.5 (12.0) after induction of anaesthesia and then remained below 70 throughout surgery. However, there was an important interindividual variability in bispectral index values despite standardized dosages of fentanyl and midazolam. There was no significant correlation between the bispectral index values in the pre-intubation and pre-incision period and the changes in systolic blood pressure during endotracheal intubation and sternotomy, respectively. In conclusion, the large intersubject variability in the bispectral index values should be investigated further in the light of the great variability in the clinical effects of midazolam and fentanyl. The lack of significant correlation between the bispectral index values and the haemodynamic responses suggest that the bispectral index, which is a helpful monitor of anaesthetic depth, is not a very reliable monitor of global anaesthetic adequacy during total intravenous anaesthesia with a combination of midazolam and fentanyl in cardiac surgical patients.

Older women's experiences with sternotomy.

While incision and subsequent scarring is a feature of all surgery, in cardiac surgery the sternotomy incision is significant and central to the body, separating the chest in half between the breasts. Increasingly older women count for a larger proportion of patients undergoing cardiac surgery each year in Australia yet there has been limited exploration of their experiences with sternotomy. A phenomenological approach was used to elicit the experiences of older women who had undergone cardiac surgery. In-depth interviews with four older women revealed a range of ways in which these women were affected by their sternotomy and their whole experience of cardiac surgery. Findings from this project provide insight into practical issues affecting these women and may assist nurses in the assessment and planning of care and education for older women having cardiac surgery, particularly in the areas of preparation for cardiac surgery and body image.

Unusual complication of sternotomy: bone fragment induced right ventricular rupture after mitral valve replacement surgery.

Major surgical complications following open cardiac procedures via median sternotomy are infrequent but potentially devastating events. We report on a unique, fatal complication of median sternotomy. A 44-year-old woman underwent mitral valve replacement for endocarditis related to intravenous drug abuse. Twenty days after the surgery, she presented to the emergency department in acute distress, and died of cardiac tamponade soon after admission. Postmortem examination revealed a defect in the right ventricular wall caused by a bone fragment resulting from the median sternotomy.

Surgical treatment of bilateral hydatid disease of the lung via median sternotomy: experience in 60 consecutive patients.

Sixty patients who underwent operation between 1979-1987 for bilateral pulmonary hydatid disease using median sternotomy approach are reported on. Although some authors prefer two-stage thoracotomy and operate on the side with the larger cyst first, or perform simultaneous bilateral thoracotomies, we have preferred one-stage operation via median sternotomy. There were 29 female and 31 male patients, ranging in age from 5 to 55 years (mean 26.4 +/- 6.3). A total of 173 cysts were operated in 120 lungs. The usual operative technique was cystotomy and capitonnage. Operative and postoperative courses were uneventful in all but three cases (5%). The causes of mortality in these patients were excessive hemorrhage, mediastinitis, and septic shock respectively. It is concluded that median sternotomy is a better alternative method for the treatment of bilateral hydatid disease of the lung, as the duration of hospitalisation is shorter, the approach is better tolerated by the patients than thoracotomy, and it possibly prevents a second general anesthesia.

Histologically verified bone wax (beeswax) granuloma after median sternotomy in 17 of 18 autopsy cases.

AIM: To evaluate the sternum from ordinary or forensic autopsy cases with a midline sternal cutaneous scar macro- and microscopically and using computed tomography (CT) to detect if the haemostatic bone sealant bone wax (beeswax) had been applied after median sternotomy and if the bone wax had elicited inflammation. METHODS: During a 3-year period, the sterna of 18 consecutive cadavers (15 ordinary autopsies, 3 forensic) who prior to death had undergone surgery with median sternotomy were examined macro- and microscopically and with CT. In addition, one virgin sternum was smeared with bone wax at the upper half after bench sternotomy, sutured and examined with CT. Unused bone wax was examined with CT for attenuation measurements. RESULTS: Macroscopically, bone wax was seen in 17 of 18 sterna. Acute inflammation was found in one, chronic inflammation and foreign body multinucleated giant cells were seen around the bone wax in 17 sterna. No inflammation was found in one. CT could only detect foci in the operated sterna with attenuation values from -45 to +20 Hounsfield units (HU) and values about -80 HU were found in the virgin sternum. Unused bone wax measured about -100 HU. CONCLUSIONS: Bone wax is non-resorbable and induces chronic inflammation in the operated sternum up to 10 years after application. Measurement of Hounsfield units with CT of the operated sterna could not verify bone wax granuloma.

Short-term changes in pulmonary function and respiratory movements after cardiac surgery via median sternotomy.

OBJECTIVE: To study the changes in bilateral respiratory motion and pulmonary function following sternotomy and the relationships between the changes in respiratory movements, spirometry, radiographic analyses, and several intra-operative surgical characteristics. DESIGN: Respiratory motion during deep breathing and lung volumes were measured in 20 patients (mean age 65 years, SD 16) before and after median sternotomy. Chest x-rays were analyzed pre- and postoperatively and a variety of perioperative variables were measured. RESULTS: Average abdominal motion decreased to 57% of preoperative values bilaterally 1 week postoperatively, the average lower thoracic motion decreased to 72%, and the average upper thoracic motion decreased to 87%, whereas the right upper thoracic motion increased 3% compared with preoperative values. Lung volumes decreased to around 60% of preoperative values (p<0.05). Significant correlations were found between the decrease in pulmonary function and the mean respiratory movements. Abnormal chest radiographs were found in all patients. CONCLUSION: The breathing pattern before sternotomy is predominantly abdominal but moves to a thoracic and upper thoracic pattern postoperatively and is associated with reduced pulmonary function. Therapeutic interventions aimed at correcting the less effective upper thoracic breathing pattern should likely be implemented.

Dysaesthesia associated with sternotomy for heart surgery.

BACKGROUND: Chronic pain occurs in 40-50% patients following cardiac surgery. Dysaesthesia, either in the form of heightened or diminished skin sensation, are frequently associated with chronic neuropathic pain. Therefore, dysaesthesia in the early postoperative period may predict chronic pain. However, the character and causes of dysaesthesia in the early postoperative period are unknown. The aim of this study was to investigate the incidence, extent, and causes of dysaesthesia following cardiac surgery by sternotomy. METHODS: In a prospective cohort study, 50 patients undergoing sternotomy for cardiac surgery were admitted to the study: 38 underwent coronary artery bypass graft (CABG), nine valve surgery, and three combined surgery. Forty-eight hours postoperatively, acute pain was measured by four-point verbal scale. Manual pinprick and cotton wool brushing was used to detect the areas of dysaesthesia. RESULTS: Some form of dysaesthesia was found in 27 (54%) of the patients. Using multivariate regression analysis, the total area of dysaesthesia was positively associated with CABG surgery and the severity of postoperative pain (P<0.001). CONCLUSION: Dysaesthesia is common in the early postoperative period following cardiac surgery using a sternotomy and is associated with CABG surgery. The association with severity of pain may indicate a neuropathic element that is unrelieved by conventional opioid analgesia.

Median sternotomy wound complication: the effect of reconstruction on lung function.

The objective of the study was to evaluate the lung function of patients with median sternotomy wound complication during the early postmedian sternotomy period and to compare the long-term pulmonary effects of reconstruction using pectoralis major and rectus abdominis muscle flaps. The percentage of predicted, standardized forced vital capacity (FVC); the standardized forced expiratory volume in 1 second (FEV1), and FEV1/FVC ratios of 45 patients with a median sternotomy wound complication were evaluated before and at a mean time of 10.6 months after wound reconstruction. Both mean FVC and FEV1 increased after wound revision compared with the prereconstruction results (8.4% and 9.2% increase, respectively). Patients with painful chest wall movement had the worst (60%) mean FVC and FEV1 before reconstruction when compared with a nonpainful complication. Reconstruction with a muscle flap was followed by an increase of 8.6% and 7.3% in FEV1 and FVC, respectively, from prereconstruction results. However, long-term results indicate that these patients have a mild, restrictive impairment of their lung function tests (LFTs), with about 80% of the predicted FVC and FEV1. Among the muscle flaps, the best improvement and best long-term LFT results were after sternectomy and reconstruction with a pectoralis major muscle flap as compared with a rectus abdominis muscle flap. Sternectomy and reconstruction with a muscle flap is a well-tolerated procedure associated with improvement of lung function compared with prereconstruction values. A pectoralis major muscle flap should be the first choice for muscle flap reconstruction while a rectus abdominis muscle flap should be reserved only for patients with good LFTs before reconstruction.

Infected median sternotomy wound. Successful treatment by muscle flaps.

The purpose of this paper is to present the experience at Emory University Hospital with the infected median sternotomy wound and to offer a treatment plan for those patients recalcitrant to the usual therapy of debridement and closed catheter irrigation with antimicrobial agents. When standard treatment fails, we proceed not only with the necessary thorough debridement to convert the wound to a relatively clean one but also concomitant closure by pectoralis major muscle flaps to completely obliterate dead space. Transposition flaps of rectus abdominus muscle or omentum are used when necessary to complete the closure. In the initial phase of this study, there were 3,239 patients who underwent open heart procedures through a median sternotomy approach in the years 1975 through 1978. In the 50 patients who had wound infections (1.54%), there were nine deaths. Three were thought to be unrelated to the sternal wound infection, four patients ruptured the ventricle or aorta, two patients died of generalized sepsis. Of these 50 patients, 22 responded to simple drainage; 28 had involvement of the mediastinum (0.86%). Of the 28 patients, 25 had debridement and closed mediastinal irrigation by catheter. Fourteen of these 25 did not respond. In these failing patients, 12 were treated by further debridement and closure by muscle flaps. Nine of these 12 were rescued. In the past nine months, an additional 1,052 patients had an open heart procedure. Of these, 11 had a median sternotomy infection. There have been no deaths in this latter group of patients, most of whom were treated by the muscle flap procedure. In addition to the improvement in mortality, morbidity has been reduced substantially. This procedure provides for a rational approach that we have found to permit salvage of a high percentage of patients who failed conventional closed irrigation techniques.

Management of the infected median sternotomy wound with muscle flaps. The Emory 20-year experience.

OBJECTIVE: The purpose of the study is to define those patient variables that contribute to morbidity and mortality of median sternotomy wound infection and the results of treatment by debridement and closure by muscle flaps. BACKGROUND: Infection of the median sternotomy wound after open heart surgery is a devastating complication associated with significant mortality. Twenty years ago, these wounds were treated with either open packing or antibiotic irrigation, with a mortality approaching 50% in some series. In 1975, the authors began treating these wounds with radical sternal debridement followed by closure using muscle or omental flaps. The mortality of sternal wound infection has dropped to < 10%. METHODS: The authors' total experience with 409 patients treated over 20 years is described in relation to flap choices, hospital days after sternal wound closure, and incidence rates of morbidity and mortality. One hundred eighty-six patients treated since January 1988 were studied to determine which patient variables had impact on rates of flap closure complications, recurrent sternal wound infection, or death. Variables included obesity, history of smoking, hypertension, diabetes, poststernotomy septicemia, internal mammary artery harvest, use of intra-aortic balloon pump, and perioperative myocardial infarction and were analyzed using chi square tests. Fisher's exact tests, and multivariable logistic regression analysis. RESULTS: The mortality rate over 20 years was 8.1% (33/49). Additional procedures for recurrent sternal wound infection were necessary in 5.1% of patients. Thirty-one patients (7.6%) required treatment for hematoma, and 11 patients (2.7%) required hernia repair. Among patients treated since 1988, variables strongly associated with mortality were septicemia (p < 0.00001), perioperative myocardial infarction (p = 0.006), and intra-aortic balloon pump (p = 0.0168). Factors associated with wound closure complications were intra-aortic balloon pump (p = 0.0287), hypertension (p = 0.0335), and history of smoking (p = 0.0741). Factors associated with recurrent infection were history of sternotomy (p = 0.008) and patients treated for sternal wound infection from 1988 to 1992 (p = 0.024). Mean hospital stay after sternal wound reconstruction declined from 18.6 days (1988-1992) to 12.4 days (1993-1996) (p = 0.005). To clarify management decisions of these difficult cases, a classification of sternal wound infection is presented. CONCLUSIONS: Using the principles of sternal wound debridement and early flap coverage, the authors have achieved a significant reduction in mortality after sternal wound infection and have reduced the mean hospital stay after sternal wound closure of these critically ill patients. Further reductions in mortality will depend on earlier detection of mediastinitis, before onset of septicemia, and ongoing improvements in the critical care of patients with multisystem organ failure.

Surgical exposure of the left subclavian artery by median sternotomy and left supraclavicular extension.

OBJECTIVE: To evaluate the feasibility of surgical exposure of the full length of the left subclavian artery using a median sternotomy and left supraclavicular extension. DESIGN: Anatomic study of five cadavers, and case review of four patients with blunt trauma to the proximal left subclavian artery. MATERIALS AND METHODS: A median sternotomy with left supraclavicular extension was performed on five cadavers and four patients. The depth of various portions of the subclavian artery was measured. Photographs of the dissections were used to document anatomic relationships and to serve as a basis for pen and ink drawings. The hospital records of four patients in which this exposure was used were reviewed for operative details. MEASUREMENTS AND MAIN RESULTS: The left subclavian artery was readily exposed from its origin on the aortic arch to its termination as the axillary artery in all cadaver dissections, including one who was more than 300% ideal body weight. The first portion of the subclavian artery lay at an average wound depth of 6.0 cm, with a mean length of 4.7 cm. The same surgical approach was used for the care of four patients who sustained blunt trauma to the first portion of the left subclavian artery and permitted expeditious control and excellent exposure for placement of a proximal subclavian interposition graft in two, a proximal subclavian to axillary artery graft in the third, and resection and end-to-end anastomosis in the fourth. CONCLUSIONS: Median sternotomy with left supraclavicular extension provides rapid, safe, and reliable exposure of all portions of the left subclavian artery without the morbidity associated with clavicular resection, thoracotomy, or a "trapdoor" incision. Furthermore, the ability to perform this procedure in the supine position allows access to the abdominal cavity, the neck, and the extremities, which often require concomitant operative intervention in a patient with multiple injuries.

CO2 laser sterilization in the surgical treatment of infected median sternotomy wounds.

BACKGROUND: We examined the use of CO2 laser sterilization in the surgical treatment of infected median sternotomy wounds. Deep wound infection after median sternotomy is infrequent (1% to 5% of all cases) but is associated with significant morbidity, mortality, and cost. METHOD: Twenty-four consecutive patients with median sternotomy wound infection were treated by one plastic surgeon using a CO2 laser to sterilize wounds after debridement and before flap closure. The rectus abdominis muscle flap was primarily used, but the choice of muscle flap was case dependent. RESULTS: To date, no patient in this series has had postoperative wound infection, breakdown, or flap loss. One patient did have superficial skin loss. CONCLUSION: Although the morbidity rate was 17%, all patients had intact wounds. None of the 5 deaths was related to wound infection. We found that CO2 laser sterilization in the surgical treatment of sternal wound infections decreased morbidity, mortality, and cost.

A randomized, placebo-controlled, double-blind, prospective clinical trial of silicone gel in prevention of hypertrophic scar development in median sternotomy wound.

BACKGROUND: Hypertrophic scarring caused by sternotomy is prevalent among Asians. The effectiveness of silicone gel in scar prevention may influence the decision of surgeons and patients regarding its routine use during the postoperative period. METHODS: The authors conducted a randomized, placebo-controlled, double-blind, prospective clinical trial. The susceptibility to scar development varied among patients; therefore, sternal wounds were divided into the upper half and the lower half. Two types of coded gel prepared by an independent pharmacist were used on either half. Thus, selection and assessment biases and confounders were eliminated. RESULTS: One hundred wounds in 50 patients were randomized into two arms, 50 control and 50 silicone gels. The median age was 61 years and there were 34 men and 16 women. Ethnic distribution was 28 Malays, 18 Chinese, and four Indians. No side effect caused by the silicone gel was noted. Ninety-eight percent of patients had moderate to good compliance. The incidence of sternotomy scar was 94 percent. At the third month postoperatively, the silicone gel wounds were scored lower when compared with the control wounds. The differences were statistically significant in all parameters, including pigmentation (p = 0.02), vascularity (p = 0.001), pliability (p = 0.001), height (p = 0.001), pain (p = 0.001), and itchiness (p = 0.02). CONCLUSIONS: The effect of silicone gel in prevention of hypertrophic scar development in sternotomy wounds is promising. There are no side effects and patients' compliance is satisfactory. This study may popularize the use of silicone gel in all types of surgery to minimize the formation of hypertrophic scars in the early postoperative period.
