目的观察腓动脉和胫后动脉穿支显微解剖特点，应用腓动脉或胫后动脉穿支蒂螺旋桨皮瓣修复小腿远端及足踝部软组织缺损创面，探讨其并发症防治措施。方法2011年3月至2011年4月，对5具新鲜尸体共10侧小腿标本，用红色乳胶灌注胭动脉、蓝色乳胶灌注静脉，解剖并观察统计腓动脉和胫后动脉穿支数量、长度、走行角度、血管直径和动静脉伴行情况等指标；从2011年6月至2013年6月，对47例小腿远端以及足踝部软组织缺损病例用穿支蒂螺旋桨皮瓣修复，观察临床疗效并统计并发症发生率，探讨并发症防治的方法。结果腓动脉和胫后动脉共发出穿支92支，其中有2条伴行静脉的有52支，有1条伴行静脉的有37支，伴行静脉缺如的1支，还有2支腓动脉穿支穿深筋膜后共用1条伴行静脉进入皮肤。腓侧在距外踝（3．0±1．0）cm和（8．0±2．O）cm处、胫侧在距内踝（5．0±1．0）cm和（8．0±1．0）cm处有较为恒定的穿支血管穿出深筋膜进入皮肤。36例腓动脉穿支蒂螺旋桨皮瓣其穿支穿出深筋膜距离外踝距离6—18cm，平均10．1cm。其中24例穿支位置在距外踝（8．0±2．0）cm范围内；11例胫后动脉穿支穿出深筋膜距离内踝6—18cm，平均9．5cm，其中有6例穿支位置在距内踝（8．0±1．0）cm范围内；并发症包括1例皮瓣下积血，1例感染，1例供区植皮坏死．13例静脉回流障碍，其中4例出现远端部分坏死。结论以腓动脉穿支和胫后动脉穿支为蒂的螺旋桨皮瓣外表美观，操作简单，是修复小腿远端及足踝部创面的首选方案之一；腓动脉在距外踝（8．0±2．0）cm范围内穿出深筋膜的穿支恒定，长度以及血管口径适合，是设计螺旋桨皮瓣血管蒂的最佳选择。
Objective The research expects to investigate the gross anatomical characteristics of the perforating branches of posterior tibia] artery and peroneal artery and repair the soft tissue defect in distal termination of leg and around the foot and ankle by using the perforator pedicled propeller flap of the two arteries. The prevention measures for the complications were also explored. Methods From March, 2011 to April, 2011, concerning the specimens of 10 sides of 5 fresh cadavers, red latex was peffused into the popliteal arteries while blue latex was perfused into the veins. Then, after anatomization, the indexes, including the number, length, orientation angles, vessel diameter and the concomi- tant relationship between the artery and vein, of the perforating branches of posterior tibial artery and peroneal artery were recorded. From June, 2011 to June, 2013, 47 cases with soft tissue defect in distal termination of leg and around the foot and ankle were treated by repairing the perforator pedicled propeller flap. On this basis, the clinical effect was observed and the complication rate was calculated so as to study the prevention methods for the complications. Results The perforating branch occurred in 92 posterior tibia] and poronea] arteries. Among them, each of 52; arteries had 2 doncomi- tant veins, 37 presented 1 concomitant vein, and 1 had no eonoomitant vein; the perforating branches of 2 poronea] arter- ies entered into the skin by sharing 1 concomitant vein after perforating deep fascia. On fibular side, at （3.0± 1.0） cm and （8.0 ± 2.0） em from lateral malleolus, on tibia] side, at （5.0 ± 1.0） em and （8.0 ± 1.0） cm from medial：malleolus, Constant perforating vessels of peroneal artery went into the skin after perforating deep fascia. Concerning the. perforatgr pedicled propeller flaps of 36 peronea] arteries, the perforating branches were 6 to18 em and 10.1 cm on average to the lateral malleolus after perforating deep fascia. Among them, the perforating branch of 24 cases located in the range of （8.0± 2.0） cm to the lateral malleolus; the perforating branches of 11 posterior tibial arteries were 6 to18 cm with an average of 9.5 cm to the medial malleolus, after perforating deep fascia; the perforating branches of 6 cases were in the site （8.0 ± 1.0） cm from the medial malleolus. The complications included 1 case of hematocele under flap, 1 case of infection, 1 case of necrosis of skin graft of donor site, and 13 cases of venous drainage disturban- ce, among which, 4 cases were suffered with distal flap necrosis. Conehcion The texture and color of propeller flap with a beautiful surface were similar to the recipient area. The harvest of flap was simple to perform without the necessity to match the vessel. Propeller flap presents satisfied clinical effect and is one of the preferred alternatives for repairing the defect in distal termination of leg and around the foot and ankle. In the range （8.0 ± 2.0） cm from lateral malleolus, the perforating branch of peroneal artery was constant after perforating deep fascia with suitable length and vessel diameter. Therefore, peroneal artery is the optimal choice for designing pedicled propeller flap.
