A 67-year-old male patient required surgical management of an abdominal aortic aneurysm. A contrast-enhanced computed tomography showed a saccular infrarenal abdominal aortic aneurysm, with occlusion of the origins of the celiac artery, superior mesenteric artery, and inferior mesenteric artery. An aortography revealed large amounts of blood flow from capillaries around the abdominal aorta to the inferior mesenteric artery and retrograde blood flow to the meandering mesenteric artery through the superior rectal artery. Considering the risk of bowel ischemia, we performed endovascular aneurysm repair with mesenteric artery bypass. The operation was successful, and the postoperative course was uneventful. This procedure may be useful and less invasive.
一名67岁男性患者需要对腹主动脉瘤进行手术治疗。增强计算机断层扫描显示为肾下腹主动脉瘤囊状，腹腔干动脉、肠系膜上动脉和肠系膜下动脉起始部闭塞。主动脉造影显示大量血流从腹主动脉周围的毛细血管流向肠系膜下动脉，并通过直肠上动脉向蜿蜒的肠系膜动脉逆向血流。考虑到肠道缺血的风险，我们进行了肠系膜动脉搭桥的血管内动脉瘤修复术。手术成功，术后过程顺利。该手术可能有用且侵入性较小。
