摘要
目的通过对以腓肠外侧神经-小隐静脉血管为蒂的皮瓣的解剖学观察，探讨其临床应用效果，并对该术式进行评价。方法10侧下肢灌注红色乳胶，20只截肢的下肢行解剖观察；临床于小腿设计以腓肠外侧神经-小隐静脉血管为蒂皮瓣修复下肢组织缺损，术中保留腓肠内侧神经，不结扎小隐静脉的远心端。结果小腿存在以皮神经、小隐静脉为中心的血管网，与深筋膜、皮下血管网相互吻合；腓肠内、外侧神经平均距外踝上（8．5±0．8）cm；63例临床应用效果良好，足跟及足外侧感觉恢复满意。结论保留腓肠内侧神经对保留足部感觉有积极意义，腓肠外侧神经-小隐静脉血管蒂皮瓣血运丰富、成活可靠。
Objective To investigate the practical anatomy and clinical applications of the lateral sural nerve-lesser saphenous vein vascular plexus island flap with median sural nerve preserved. Meth-ods Ten lower limbs injected with color red latex and 20 fresh limbs were observed. Based on ana-tomical studies, the island flap pedicled with the vascular axis of lateral sural nerve and lesser saphe-nous vein was designed for clinical application in 63 cases. In procedure, the median sural nerve were preserved in donor site and the distal end of the lesser saphenous vein were not ligated. Results The accompanying arteries formed a favourable vascular plexus around the nerve and the vein, lied along the lateral sural nerve and the lesser saphenous vein and nourished the skin through cutaneous bran ches. The distance of the lateral ankle to the confluent of lateral and median sural nerve was （8.5±0.8） cm. 63 patients with soft tissue defects in the distal leg and foot were repaired. Their appearance and function were satisfaction withoul feeling lose in the heel and lateral side of the foot. Conclusions The lateral sural nerve-lesser saphenous vein vascular island flap is a reliable source of soft tissue to cover defects in the lower leg and foot. This flap has sufficient blood supply and high survival rate without the sacrifice of the median sural nerve.
