In a severely injured leg with acute limb ischemia, both immediate revascularization of an endangered part and coverage of soft tissue defect are crucial to limb salvage. In this article, we report a case of an anterolateral thigh free flap with interposition graft of descending branches of the lateral circumflex femoral vessels. A 18-cm-long graft was harvested and used to replace the injured anterior tibial vessels. One month later, a duplex sonogram revealed intact circulation to both the interposition graft and the flap. Despite anatomic inconstancy, the anterolateral thigh free flap is commonly utilized in reconstructive surgeries. When descending branches of the lateral femoral circumflex vessels were included sufficiently, its pedicle can be used to bridge a vascular defect in the extremity while covering soft tissue defect.
在伴有急性肢体缺血的严重受伤腿部，对濒危部位立即进行血运重建以及覆盖软组织缺损对于挽救肢体至关重要。在本文中，我们报告了一例采用旋股外侧血管降支间置移植的股前外侧游离皮瓣病例。切取了一段18厘米长的移植血管，用于替代受损的胫前血管。1个月后，双功超声检查显示间置移植血管和皮瓣的血流通畅。尽管存在解剖变异，但股前外侧游离皮瓣在重建手术中仍被广泛应用。当充分包含旋股外侧血管的降支时，其蒂部可用于桥接肢体的血管缺损，同时覆盖软组织缺损。
