A 71-year-old man was referred to our hospital under a diagnosis of abdominal aortic aneurysm (AAA). The past history of the patient included a sigmoid colectomy at 64 years old for an ischemic colitis. The maximum diameter of AAA was still 45 mm, and the inferior mesenteric artery (IMA) was aneurysmal and was 30 mm in diameter and thrombosed. The growth rate in the diameter of IMA aneurysm was 5 mm per year for the last 3 years. The patient successfully underwent endovascular aneurysm repair (EVAR), and the postoperative course was good. At 5 years after EVAR, computed tomography revealed a decrease in the diameter of both aneurysms.
一名71岁男性因腹主动脉瘤（AAA）被转诊至我院。患者既往史包括64岁时因缺血性结肠炎行乙状结肠切除术。AAA的最大直径仍为45毫米，肠系膜下动脉（IMA）呈瘤样扩张，直径为30毫米且已形成血栓。在过去3年中，IMA动脉瘤直径的增长率为每年5毫米。患者成功接受了血管内动脉瘤修复术（EVAR），术后恢复良好。EVAR术后5年，计算机断层扫描显示两个动脉瘤的直径均减小。
