Immediate outcome of endovascular treatment of ruptured juxtarenal aneurysm with parallel stents

Abstract Rupture of an abdominal aortic aneurysm is an event with a high mortality rate and treatment is a medical emergency. Endovascular treatment of these aneurysms has become established as a minimally invasive alternative to classical open surgery and is now the first-choice option. However, 20 to 50% of patients with abdominal aortic aneurysms do not have anatomy favorable for endovascular treatment because of a short aneurysm neck or because visceral branches are involved by the aneurysm. We report the case of a 70-year-old patient who underwent endovascular repair of a ruptured juxtarenal aneurysm with deployment of parallel stents in the renal arteries (in a chimney technique). Clinical data and details of the procedure are reported. Technical success was achieved and there were no postoperative complications.

摘要：腹主动脉瘤（abdominal aortic aneurysm）破裂是一类致死率极高的急症，其治疗需作为医学急诊处理。针对此类动脉瘤的血管腔内治疗（endovascular treatment）现已成为传统开放手术的微创替代方案，并成为当前首选治疗手段。然而，20%~50%的腹主动脉瘤患者因瘤颈过短或动脉瘤累及内脏分支血管，其解剖结构并不适合开展血管腔内治疗。本文报告1例70岁患者，其因破裂型肾旁动脉瘤接受血管腔内修复术，术中于肾动脉内置入并行支架（采用烟囱技术（chimney technique））。本文报告了该病例的临床资料与手术操作细节。本次手术获得技术成功，术后未出现任何并发症。
