Isolated aneurysms of the external iliac artery are rare in patients with fibromuscular dysplasia. In this study, we report the case of a 74-year-old man with advanced gastric cancer who was found to have a medium-sized aneurysm of the external iliac artery (35 mm) on preoperative computed tomography angiograms. The patient underwent laparoscopic gastrectomy followed by replacement of the external iliac artery 6 months later. Histological examination of biopsy specimens revealed fibromuscular dysplasia. The 6 month postoperative course was uneventful. Such a case of external iliac artery aneurysm caused by fibromuscular dysplasia is very rare, and open surgery is recommended for its removal.
在患有纤维肌发育不良的患者中，孤立性髂外动脉瘤很少见。在本研究中，我们报告了一例74岁晚期胃癌男性患者，其在术前计算机断层血管造影中被发现患有中等大小的髂外动脉瘤（35毫米）。该患者接受了腹腔镜胃切除术，6个月后进行了髂外动脉置换术。活检标本的组织学检查显示为纤维肌发育不良。术后6个月病程平稳。这种由纤维肌发育不良引起的髂外动脉瘤病例非常罕见，建议采用开放手术切除。
