Massive localized lymphedema (MLL) in bariatric candidates.

BACKGROUND: Mild lymphedema of lower limbs and eventually abdomen is not exceedingly rare in morbid obesity. However, few large symptomatic masses have been reported. In a consecutive series of patients, all requiring resection of the lesion before bariatric treatment, clinical features and surgical findings are described, aiming to clarify the nature of this intricate problem. METHODS: Subjects (n=4, 50% females, age 34.0+/-13.7 years (19-53), BMI 56.4+/-10.5 kg/m(2) (44.1-73.1) displayed lesions on the anteromedial aspect of the thigh (n=3) and hypogastrium (n=1). All reported episodes of intertrigo of local skin-folds in the preceding years, managed by local care and antibiotics. The mass was described as a serious nuisance, impairing walking, dressing and personal hygiene. RESULTS: The mass was surgically removed without requirement for blood transfusion except in the case of one huge mass. Complications were relatively minor and consisted of partial skin dehiscence and lymph leakage for 2-3 weeks. Histologically, a complex pattern was observed including skin hypertrophy, edema, fibrosis, foci of microabscesses and dilated blood vessels, along with the pathognomonic lymphangiectasia. On follow-up to 6 months, improvement or restoration of the ability to walk occurred, with no additional skin infection and no recurrence. CONCLUSIONS: 1) Surgical treatment was effective. 2) Functional rehabilitation was achieved. 3) No recurrence was observed within the follow-up period.

The problem of subepidermal blisters in neoformed integuments.

The present paper is a review of articles on the onset of subepidermal blisters in neoformed integuments. Considering the discrepancy between the literature data and our clinical experience concerning spontaneous onset of subepidermal blisters in neoformed integuments, we decided to conduct an extensive review of the literature. The main finding arising from it was the lack of characterization of the neoformed integument where the blisters were formed. These were normally referred to only by clinical descriptions such as "spontaneously healed burn", "grafted site", "donor site", "epidermal graft". Anatomical and clinical pathology aspects such as the formation mechanism of these integuments and the respective tissues that comprise them were not considered. We concluded that by adopting more precise criteria to classify neoformed integuments we would realize that split thickness grafts are not susceptible to blister formation.

Tensor fasciae latae perforator flap: minimizing donor-site morbidity in the treatment of trochanteric pressure sores.

BACKGROUND: To report a new technique with less morbidity for coverage of trochanteric defects, an anatomical and clinical study was performed. METHODS: Twenty-four fresh cadavers were dissected. The following parameters were measured: origin, location, number, and length of the perforating vessels. In addition, a clinical study was performed on 21 patients with trochanteric pressure sores. RESULTS: The anatomical study of 24 fresh cadavers revealed the constant presence of perforator pedicles anterior to the greater trochanter, which provides an adequate arc of rotation arc for flap harvest without sacrificing the underlying muscles. The mean length of the pedicles was 9.59 +/- 2.16 cm. This flap is nourished by perforator vessels arising from the ascending branch of the lateral circumflex femoral artery, which arises from the deep femoral artery and runs through the intermuscular septum, tensor fasciae latae, and rectus femoralis muscles. In this study, flaps were raised based on perforators located preoperatively using a unidirectional Doppler probe. Good results were obtained with primary closure of the donor site, with only two donor-site dehiscences. CONCLUSIONS: This flap is an alternative to myocutaneous flaps, as it preserves local musculature without functional sequelae in patients who walk. It also preserves the local musculature in the event of recurrence, as is usually seen in paralytic patients with pressure sores.

Treatment of post-traumatic tibial osteomyelitis using microsurgical flaps.

Between 1994 and 1998, the authors treated 70 patients presenting with post-traumatic tibial osteomyelitis. Eighty-five percent were males, with a mean patient age of 32 years. The mean duration of the disease was 2 years. Fifty-one percent were of type IV in the Cierny-Mader classification. The mean follow-up period was 36 months. Case management was through thorough debridement, antibiotic therapy, and soft-tissue reconstruction using free flaps: latissimus dorsi (39.4 percent), scapular (28.2 percent), lateral arm (19.7 percent), and anterior serratus (12.7 percent). To evaluate the results, the control of infection and the quality of the soft tissue repaired were considered. The success rate was 90 percent. The authors conclude that their described method constitutes an effective treatment for post-traumatic tibial osteomyelitis.

Subfascial transaxillary breast augmentation without endoscopic assistance: technical aspects and outcome.

BACKGROUND: Although transaxillary breast augmentation (TBA) is a well-studied procedure, few previous reports exist concerning the subfascial technique, especially without endoscopic assistance. This study aimed to analyze the feasibility of the technique after breast augmentation in terms of its indication, surgical technique, limitations, and clinical outcome. METHODS: For this study, 42 patients underwent TBA without endoscopic assistance. The technique was indicated for patients with breasts of small or moderate volume without ptosis, patients who wanted no breast scars, and patients who had a poorly defined inframammary fold. The mean follow-up period was 16 months. Implant and incision approach complications were evaluated. Information on patient satisfaction was collected. RESULTS: A total of 14 complications occurred in 42 patients, all of them minor. Axillary incision-related complications occurred in 26% of the patients, as represented by a late axillary subcutaneous band (119%), sensory loss in the inner aspect of the arm (71%), and a hypertrophic scar and small wound dehiscence (71%). No patient presented with capsular contracture, visible rippling, or infection. Most of the patients (93%) were either very satisfied or satisfied with their result, and none regretted the surgery. CONCLUSION: The TBA procedure without endoscopic assistance is a simple and reliable technique for breast augmentation. Most of the complications in this study were minor and predictable. They did not interfere with the aesthetic outcome nor the normal postoperative recovery. With TBA, success depends on patient selection as well as careful intra- and postoperative management.
