目的总结肾动脉下腹主动脉瘤腔内修复术的初步经验。方法对我院2006年8月至2009年3月期间收治的10例肾动脉下腹主动脉瘤患者在全麻下采用单侧或双侧股动脉入路置入带膜支架行腔内修复术。结果10例肾动脉下腹主动脉瘤采用腔内修复治疗,带膜支架置入顺利,立即DSA7例动脉瘤体消失,Ⅰ型内瘘2例,经支架附着点球囊扩张后内瘘即刻消失。随访3～30个月(平均10个月),2例术后切口淋巴瘘,经换药痊愈。全部患者肢体血运正常。1例发生Ⅱ型内瘘,未经治疗,随访2个月后消失。结论腔内修复术对肾动脉下腹主动脉瘤是一种创伤小、恢复快及效果好的治疗方法。
Objective To summarize the preliminary experience of endovascular repair of renal artery with inferior abdominal aortic aneurysm. Methods Ten patients with inferior abdominal aortic aneurysm of renal artery admitted from August 2006 to March 2009 in our hospital underwent unilateral or bilateral femoral artery approach underwent endovascular stent placement. Results 10 cases of renal artery inferior abdominal aortic aneurysm were treated by endovascular repair. Stenting was performed successfully. Immediate DSA7 aneurysm disappeared and type I fistula was found in 2 cases. The internal fistula disappeared immediately after balloon dilation. All cases were followed up for 3 to 30 months (average 10 months). Two cases of incisional lymphatic fistula were cured by dressing change. All patients with normal blood circulation limbs. One case had Type II fistula, without treatment, disappeared after 2 months follow-up. Conclusions Endovascular repair is a less invasive, faster and effective treatment for the lower abdominal aortic aneurysm of the renal artery.
