Both coarctation of the abdominal aorta, and splenic artery aneurysm reside in the hilus, a rare but extremely important pathological condition. Herein a 36-year-old woman hospitalized for uncontrolled hypertension is presented. Aortography demonstrated segmental abdominal aortic coarctation with left renal artery and splenic artery aneurysms. Medical control of hypertension was not possible and thoracoabdominal bypass with a prosthetic graft was undertaken. Left renal artery aneurysm was resected and aorto-renal saphenous vein bypass was performed. But splenic artery aneurysm was left in situ because it was asymptomatic and less than 2 cm in diameter. Postoperatively the patient was normotensive. Although the pathogenesis of such lesions remain unknown, it may be to congenital or related medial degeneration as demonstrated histologically.
腹主动脉缩窄和脾动脉瘤均位于肾门处，这是一种罕见但极其重要的病理状况。本文报告了一名因高血压控制不佳而住院的36岁女性。主动脉造影显示腹主动脉节段性缩窄，并伴有左肾动脉和脾动脉瘤。药物治疗无法控制高血压，遂进行了胸腹人工血管搭桥术。切除了左肾动脉瘤并进行了主动脉-肾隐静脉搭桥术。但脾动脉瘤因无症状且直径小于2 cm而原位保留。术后患者血压恢复正常。尽管此类病变的发病机制尚不清楚，但组织学显示可能与先天性或相关的中层退变有关。
