RESUMEN
BACKGROUND: Large, full-thickness infrainguinal wounds following revision revascularization procedures of the lower extremity are a challenging complication for reconstructive surgery. Frequently, these patients present with various comorbidities and after several previous reconstructive attempts. Therefore no straightforward soft tissue reconstruction is likely. METHODS: Patients who presented with large, complex inguinal wounds for soft tissue reconstruction were analyzed retrospectively in terms of flap choice, outcome, and complication rates. A focus was set on the reconstructive technique and a subgroup analysis was assessed. RESULTS: Nineteen patients (11 men, 8 women) who received 19 flaps (17 pedicled, 2 free flaps) were included in this retrospective study. Average patient age was 73.3 years (range: 53-88). Ten fasciocutaneous flaps (anterolateral thigh [ALT], 52.6%) and 9 muscle flaps (47.4%) were applied. Among muscle flaps, 3 pedicled gracilis flaps, 4 pedicled rectus abdominis flaps, and 2 free latissimus dorsi flaps were used. No flap losses were observed except 1 case of limited distal flap necrosis (gracilis group). Body mass index ranged from 19 to 37, mean 26.8. Mean surgery time in all patients was 165.9 min (range: 105-373). Revision surgery due to local wound healing problems averaged 1.6 in all patients. In all cases sufficient soft tissue reconstruction was achieved and bypasses were preserved. Lengths of stay averaged 27.2 days (range: 14-59). Mortality was considerably (10.5%) due to systemic complications (one patient died due to a heart attack 4 weeks postoperatively, another patient died due to an extensive pulmonary embolism 2 weeks postoperatively). CONCLUSIONS: Soft tissue reconstruction of complex inguinal wounds after revision vascular surgery is challenging and wound healing problems are expectable. In addition to the rectus abdominis flap the pedicled ALT flap is feasible in a broad variety of medium to large wounds. Free flap reconstruction is recommended for very large defects. A structured interdisciplinary approach is required for the management of complex wounds after vascular surgery to prevent and to deal with complications and perioperative morbidity.

BACKGROUND: Although the anterolateral thigh flap (ALT) is one of the most frequently applied free flaps in plastic surgery, it remains controversial if the flap should be raised in a sub- or suprafascial plane. The purpose of this study was to compare both harvest techniques regarding donor-site morbidity and outcomes. METHODS: We included 40 pair-matched patients, of whom 20 received a fasciocutaneous and 20 an adipocutaneous ALT free flap for extremity reconstruction. Patients were matched for age (±5 years), sex and affected extremity. Chart review focused on co-morbidities, flap dimensions, course of perforator(s), postoperative complications, and surgery time. Follow-up included sensation, range of motion, and muscle strength at the donor-site. In addition, patients rated the aesthetic and functional outcome on a scale from 1 to 6 and completed a Quality of Life 36-item Short-Form Health Survey (SF-36) as well as the lower extremity functional scale (LEFS) questionnaire. RESULTS: Chart review did not reveal any significant differences among study groups. Follow-up indicated better sensory outcomes after subfascial flap elevation, but without statistical significance. Range of motion and muscle strength were not impaired in any patient. Neither patients' ratings regarding aesthetic and functional outcomes nor scores of the SF-36 or LEFS differed significantly among study groups. CONCLUSION: Sub- or suprafascial harvest of the ALT free flap for extremity reconstruction does not impact donor-site morbidity or complications.

BACKGROUND: Bioethanol-fueled fireplaces are popular interior home decoration accessories. Although their safety is promoted frequently, actual presentations of severe burn injuries in our burn intensive care unit (ICU) have focused the authors on safety problems with these devices. In this article we want to explore the mechanisms for these accidents and state our experiences with this increasingly relevant risk for severe burn injuries. MATERIALS AND METHODS: The computerized medical records of all burn intensive care patients in our burn unit between 2000 and 2014 were studied. Since 2010, 12 patients with bioethanol associated burn injuries were identified. Their data was compared to the values of all patients, except the ones injured by bioethanol fireplaces that presented themselves to our burn ICU between the years 2010 and 2014. RESULTS: At time of admission the bioethanol patients had a mean ABSI-score of 4.8 (+/- 2.2 standard deviation (SD)). A mean of 17 percent (+/- 9.1 SD) body surface area was burned. Involvement of face and hands was very common. An operative treatment was needed in 8 cases. A median of 20 days of hospitalization (range 3-121) and a median of 4.5 days on the ICU (range 1-64) were necessary. No patient died. In most cases the injuries happened while refilling or while starting the fire, even though safety instructions were followed. In the control group, consisting of 748 patients, the mean ABSI-score was 5.6 (+/- 2.7 SD). A mean of 16.5 percent (+/- 10.1 SD) body surface area was burned. Treatment required a median of 3 days on the burn ICU (range 1-120). Regarding these parameters, the burden of disease was comparable in both groups. CONCLUSION: Bioethanol-fueled fireplaces for interior home decoration are a potential source for severe burn accidents even by intended use.
