摘要/Abstract

摘要： 目的通过分析血管化腓骨肌皮瓣制备前及制备中发现的腓动脉变异情况,探讨大型血管化游离腓骨肌皮瓣制备前选择性使用CT血管造影技术（computed tomography angiography,CTA）的必要性。方法回顾性收集单中心近10年经CTA或术中发现的各类腓动脉变异情况,分析不同腓动脉血管的分类及分布情况。结果在683例计划腓骨瓣手术患者中,16例（19侧）发现小腿腓动脉异常,其中3例为双侧腓动脉变异。在2侧小腿中发现ⅢC型变异（腓大动脉变异型）,而大多数变异（13侧小腿）为ⅢA型（胫后动脉发育不良或缺失型）;4侧小腿为新ⅢD型（胫、腓动脉低分叉型）。术前多普勒超声及体格检查仅发现2侧小腿血管异常。这些患者中,6例因制备腓骨瓣术中发现变异（术前仅做了超声及体格检查）,其中3例继续切取腓骨瓣,并采用动脉血管桥接的方法以延长腓动脉,其中1例术后出现小腿局部组织缺血、比目鱼肌部分坏死和跛行。结论为确保腓骨瓣制备后的下肢供区安全,倡导选择性地在制备长段复杂性腓骨瓣手术前进行CTA检查,而不是单纯采用多普勒超声检查。

Abstract: PURPOSE: This study was aimed to discuss and propose the necessity of selective use of CT angiography(CTA) before vascularized fibular flap harvest. METHODS: A 10-year retrospective analysis was performed to find the patients with various fibular artery(FA) abnormalities confirmed by CTA or intraoperative findings. Different FA abnormalities and their influences on peri- or intra-operative decisions were summarized. RESULTS: A total of 19 FA anomalies were found either pre- or intra-operatively in 16 patients, with 3 cases having bilateral FA anomalies. FA magna was confirmed in 2 legs, while the majority (13 legs) were with type ⅢA hypoplastic/aplastic posterior tibialis arteries, 4 legs with typeⅢD (low bifurcation). Preoperative color doppler ultrasonography(CDU) only suspected anomalies in 2 legs. Six cases proceeded with using the affected fibulas, within whom vascular grafts were used in 3 for lengthening the pedicle of FA. Two cases changed into soft tissue flaps instead of fibular flap intraoperatively. Reconstructive plans changed preoperatively for the other 8 cases, into soft-tissue free flaps, iliac bone flaps or adjacent flaps for 5, 2 and 1 retrospectively. Local ischemia, partial soleus muscle necrosis and claudication was found in 1 patient. CONCLUSIONS: CTA should be performed selectively for screening contraindications for lengthy fibular flaps when necessary.
