Objective: To explore the clinical effects of anterograde sural neurovascular flap in repairing skin and soft tissue defect around the knee. Methods: Nine patients with skin and soft tissue defect around the knee admitted to Beijing Fengtai YouAnMen Hospital from May 2011 to December 2018, were included in this retrospective descriptive study, including 8 males and 1 female, aged 16 to 65 years. The wound area after debridement ranged from 8 cm×5 cm to 18 cm×10 cm. Anterograde sural neurovascular flap was used to repair the wounds in 9 patients, with the area ranging from 9 cm×6 cm to 20 cm×12 cm. The donor sits of flaps in 2 patients were closed and sutured directly, and the donor sits of flaps in 7 patients were repaired with medial split-thickness skin graft of the ipsilateral thigh. The flap survival, complications, and follow-up after operation were recorded. Results: The flaps survived and the blood supply was good in 8 patients and the wounds were closed. One patient developed skin ischemic necrosis which was cured after three weeks of dressing change. All the skin grafts in the donor site of flap in 7 patients survived. In 6 months to 5 years of follow-up after surgery, the skin flap had good texture, color, and shape, and normal sensation. Except for one patient whose knee had poor recovery of function, the knee joint function of the other patients recovered well. Conclusions: The anterograde sural neurovascular flap has the advantages of high survival rate, satisfactory appearance and functional recovery post surgery, and is an ideal flap for repairing the skin and soft tissue defect around the knee.
目的： 探讨顺行腓肠神经营养血管皮瓣修复膝周皮肤软组织缺损的临床效果。 方法： 2011年5月—2018年12月北京丰台右安门医院收治9例膝周皮肤软组织缺损患者，纳入此回顾性队列研究，其中男8例、女1例，年龄16～65岁。本组患者清创后创面面积为8 cm×5 cm～18 cm×10 cm，均应用顺行腓肠神经营养血管皮瓣修复创面，皮瓣切取面积9 cm×6 cm～20 cm×12 cm。2例患者供瓣区直接拉拢缝合，7例患者供瓣区取同侧大腿中厚皮片移植修复。记录术后皮瓣成活情况、并发症发生情况、随访情况。 结果： 术后8例患者皮瓣全部成活，血运良好，创面封闭；1例患者出现皮肤缺血坏死，经3周换药痊愈。7例患者供瓣区移植皮片均全部成活。术后6个月～5年随访，皮瓣质地、色泽、外形良好，皮瓣感觉正常；除1例患者患膝恢复欠佳外，其余患者膝关节功能恢复良好。 结论： 顺行腓肠神经营养血管皮瓣具有皮瓣成活率高、术后外形及功能恢复较佳等优点，是修复膝周皮肤软组织缺损较为理想的皮瓣。.
