Abdominal aortic aneurysm (AAA) is a significant source of morbidity and ranked by the Centers for Disease Control and Prevention as the 15 leading cause of death among adults aged 60 to 64 years. Size confers the largest risk factor for aneurysm rupture, with aneurysms >6 cm having an annual rupture risk of 14.1%. We present the case of a 60-year-old man found on ultrasound imaging at a health fair screening to have a 15-cm AAA. Follow-up computed tomography angiography revealed an 18-cm × 10-cm unruptured, infrarenal, fusiform AAA. Giant AAAs, defined as >11 cm, are rarely described in the literature. Our patient underwent successful transperitoneal AAA repair with inferior mesenteric artery reimplantation and was discharged home on operative day 6. We believe this case represents one of the largest unruptured AAAs in the literature and demonstrates the feasible approach for successful repair.
腹主动脉瘤（AAA）是发病的一个重要原因，美国疾病控制与预防中心将其列为60至64岁成年人中第15位主要死因。瘤体大小是动脉瘤破裂的最大危险因素，直径>6 cm的动脉瘤每年破裂风险为14.1%。我们报告一例60岁男性病例，在健康博览会筛查的超声检查中发现患有15 cm的腹主动脉瘤。后续的计算机断层扫描血管造影显示为一个18 cm×10 cm、未破裂、肾下型、梭形腹主动脉瘤。定义为直径>11 cm的巨大腹主动脉瘤在文献中鲜有描述。我们的患者接受了成功的经腹腹主动脉瘤修复术并进行了肠系膜下动脉再植，术后第6天出院回家。我们认为该病例代表了文献中最大的未破裂腹主动脉瘤之一，并展示了成功修复的可行方法。
