Persistent sciatic artery is a rare embryological vascular anomaly, with an incidence of 0.01%-0.05%. Up to 60% of persistent sciatic artery patients will develop aneurysms that can subsequently lead to distal embolization and a high risk of limb loss.
Here we report a case with acute limb ischemia caused by thrombus in a right persistent sciatic artery aneurysm. The patient underwent endovascular treatment by deploying a 10 × 150 mm stent graft (Viabahn) in the persistent sciatic artery and two self-expanding bare stents (10 × 40 mm, 10 × 60 mm, SMART) in the stent graft to reinforce the radial resistive force. In addition, we conducted a literature review of articles published in PubMed from 2001 to 2018 regarding stent graft repair of complete persistent sciatic artery aneurysms. A total of 13 articles reported 13 patients with complete persistent sciatic artery aneurysms who underwent endovascular stent graft repair.
A favorable result was obtained for this patient, and computed tomographic angiography at 6 months of follow-up revealed patent stent graft. Most articles reported favorable results.
Favorable results can be achieved with endovascular stent graft repair and anticoagulation therapy for complete persistent sciatic artery aneurysms.
坐骨动脉持续存在是一种罕见的胚胎血管异常，发病率为0.01% - 0.05%。高达60%的坐骨动脉持续存在患者会发生动脉瘤，随后可导致远端栓塞和肢体丧失的高风险。
在此我们报告一例因右侧坐骨动脉持续存在性动脉瘤内血栓形成导致急性肢体缺血的病例。患者接受了血管内治疗，在坐骨动脉持续存在处植入一枚10×150mm覆膜支架（Viabahn），并在覆膜支架内植入两枚自膨式裸支架（10×40mm、10×60mm，SMART）以增强径向阻力。此外，我们对2001年至2018年发表在PubMed上关于完全性坐骨动脉持续存在性动脉瘤覆膜支架修复的文章进行了文献综述。共有13篇文章报道了13例接受血管内覆膜支架修复的完全性坐骨动脉持续存在性动脉瘤患者。
该患者取得了良好的效果，随访6个月时的计算机断层血管造影显示覆膜支架通畅。大多数文章报道了良好的结果。
对于完全性坐骨动脉持续存在性动脉瘤，血管内覆膜支架修复和抗凝治疗可取得良好效果。
