Abstract
INTRODUCTION
Large, full thickness infra-inguinal 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 and 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
19 patients (11 men, 8 women) who received 19 flaps (17 pedicled, two free flaps) were included in this retrospective study. Average patient age was 73.3 years (range: 53-88 years). 10 fascio-cutaneous flaps (ALT, 52.6%) and 9 muscle flaps (47.4%) were applied. Among muscle flaps, 3 pedicled gracilis flaps, 4 pedicled rectus abdominis flaps and two free latissimus dorsi flaps were used. No flap losses were observed except one case of limited distal flap necrosis (gracilis group). Body Mass Index (BMI) ranged from 19 to 37, mean 26.8. Mean surgery time in all patients was 165.9 minutes (range: 105-373 minutes). 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 (14 to 59 days). 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 two weeks postoperatively).
CONCLUSION
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.
