游离膝降动脉穿支皮瓣在足部软组织缺损中的应用

目的　总结应用游离膝降动脉穿支皮瓣修复足部软组织缺损的方法和临床效果。 方法　自2014年3月至2016 年12月，应用游离膝降动脉穿支皮瓣修复足部皮肤缺损8例，皮瓣面积7.0 cm×9.0 cm至9.0 cm×20.0 cm，5例以膝降动脉主干为蒂，3例以肌皮穿支为蒂。 结果　8例皮瓣全部成活，随访3~10个月，平均8个月，皮瓣的色泽、弹性、外观质地良好。 结论　膝降动脉穿支皮瓣血管蒂恒定，血管口径大小适中，皮瓣质地厚薄适中，是修复手足部皮肤缺损较适用的方法。

Clinical application of free descending genicular artery perforator flap for coverage of soft tissue defect of foot

Objective　To summarize the method and clinical efficacy of using the descending genicular artery perforator flap for resurfacing foot wounds.　Methods　The descending genicular artery perforator flap was adopted for coverage of soft-tissue defects over the foot in 8 cases between Mar, 2014 to Dec, 2016. The area of the skin flap ranged from 7.0cm×9.0 cm to 9.0 cm×20.0 cm, The perforator flaps included the genicular artery perforator flap in 5 cases, and the musculocutaneous perforator flap in 3 cases. Result　 In the 8 cases of clinical application, all flap survived uneventfully. Patients were followed up 3 to 10 months with an average of 8 months. The appearance, texture, and colour of the flaps were similar to those of the donor site.　Conclusions　The descending genicular artery perforator flap, being consistent in perforator location, moderate in vascular caliber, appropriate in skin thickness, is an effective method to repair the soft-tissue defects of the hand and foot.
