抄録

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.
