胫前动脉穿支螺旋桨皮瓣接力腓动脉终末前穿支螺旋桨皮瓣修复足踝部创面

目的探讨胫前动脉穿支螺旋桨皮瓣接力腓动脉终末前穿支螺旋桨皮瓣修复足踝部创面的疗效。方法2014年10月-2018年10月,收治18例足踝部创面患者。男12例,女6例。年龄8~56岁,平均32.8岁。致伤原因:交通事故伤11例,高处坠落伤3例,重物砸伤4例。创面部位:足背部9例,足跟4例,外踝5例。受伤至皮瓣修复时间7~34 d,平均19 d。创面范围6.0 cm×2.5 cm^11.0 cm×6.0 cm。采用大小为6 cm×3 cm^18 cm×7 cm的腓动脉终末前穿支螺旋桨皮瓣修复足踝部创面,其供区以胫前动脉穿支螺旋桨皮瓣(8 cm×3 cm^16 cm×6 cm)修复。结果术后1例腓动脉终末前穿支螺旋桨皮瓣出现瘀血肿胀,经对症处理后成活。其余皮瓣均顺利成活,供受区创面均Ⅰ期愈合。18例患者均获随访,随访时间6~15个月,平均12.5个月。末次随访时,两皮瓣外形、色泽、质地和厚度与受区基本一致,供区仅遗留线性瘢痕。腓动脉终末前穿支螺旋桨皮瓣两点辨别觉为10~12 mm,平均11 mm。根据美国矫形足踝协会(AOFAS)评分评价,获优15例、良3例,优良率为100%。结论应用胫前动脉穿支螺旋桨皮瓣接力腓动脉终末前穿支螺旋桨皮瓣修复足踝部创面,不需要牺牲主干血管,还能避免供区植皮,踝关节功能恢复满意。

Anterior tibial artery perforator propeller flap relay peroneal artery terminal perforator propeller flap for foot and ankle defect

Objective To investigate the clinical application of the anterior tibial artery perforator propeller flap relay peroneal artery terminal perforator propeller flap in repair of foot and ankle defects. Methods Between October2014 and October 2018, 18 cases with foot and ankle defects were treated. There were 12 males and 6 females with an average age of 32.8 years(range, 8-56 years). There were 11 cases of traffic accident injuries, 3 cases of falling from height injuries, and 4 cases of heavy objects injuries. The wound was at the dorsum of the foot in 9 cases, the heel in 4 cases, the lateral malleolus in 5 cases. The time from injury to flap repair was 7-34 days(mean, 19 days). The size of wound ranged from 6.0 cm×2.5 cm to 11.0 cm×6.0 cm. The foot and ankle defects were repaired with the peroneal artery terminal perforator propeller flap in size of 6 cm×3 cm-18 cm×7 cm, which donor site was repaired with the anterior tibial artery perforator propeller flap in size of 8 cm×3 cm-16 cm×6 cm. Results One patient had a hemorrhagic swelling in the peroneal artery terminal perforator propeller flap, and survived after symptomatic treatment. All recipient and donor sites healed by first intention. Eighteen patients were followed up 6-15 months(mean, 12.5 months). At last follow-up, the shape, color, texture, and thickness of the flaps in the donor sites were similar with those in the recipient sites. There were only linear scars on the donor sites. The two-point discrimination of the peroneal artery terminal perforator propeller flap ranged from 10 to 12 mm(mean, 11 mm). According to American Orthopaedic Foot and Ankle Society(AOFAS)score criteria, the results were excellent in 15 cases and good in 3 cases, with an excellent and good rate of 100%.Conclusion The foot and ankle defects can be repaired with the anterior tibial artery perforator propeller flap relay peroneal artery terminal perforator propeller flap. The procedure is not sacrificing the main vessel and can avoid the skin grafting and obtain the good ankle function.
