腓动脉是小腿的重要血管之一,腓动脉穿支皮瓣已在临床上被广泛运用。CT血管造影(CTA,CT angiography)检查被证实是术前设计皮瓣的可靠方法之一~([1,2])。在1例患者的双下肢CTA检查中,发现其左侧腓动脉及胫后动脉发生变异,现报道如下。本例患者,男,38岁,主因“右手机器伤清创术后3天”入院。入院诊断:右手背皮肤缺损并肌腱外露。拟行游离腓动脉穿支皮瓣移植修复术。为保证 The peroneal artery is one of the important blood vessels of the lower leg. The perforator flap of the peroneal artery has been widely used clinically. CT angiography (CTA, CT angiography) proved to be one of the reliable methods to design the flap preoperatively ([1,2]). In one patient’s lower extremity CTA examination, found that the left side of the peroneal artery and posterior tibial artery variability, are reported below. The patient, male, 38 years old, was hospitalized because of “right-hand machine wound debridement 3 days after surgery.” Admission diagnosis: Right back of the skin defect and tendon exposure. Proposed free peroneal artery perforator flap transplantation repair. To guarantee
