目的：总结Ⅱb型肾下型腹主动脉瘤的腔内隔绝术治疗经验。方法2007年5月至2012年12月暨南大学第二临床医学院心血管外科应用分支型覆膜支架实施腔内隔绝术治疗20例Ⅱb型肾下型腹主动脉瘤患者。采用增强CT血管成像进行随访。结果8例患者成功植入Powerlink分支型支架8枚；12例患者成功植入Zenith分支型支架12枚，支架植入成功率为100%。随访10~65个月，所有支架形态正常，没有位移发生。术后1个月复查发现Ⅱ型内漏3例，6个月时复查内漏消失。术后无其他手术相关并发症发生。结论应用分支型支架腔内隔绝能安全有效地治疗Ⅱb型肾下型腹主动脉瘤。

Objective To summarize the clinical experience of endovascular graft exclusion (EVGE) on treating type IIb infrarenal abdominal aortic aneurysms. Methods From May 2007 to December 2012, 20 patients with infrarenal abdominal aortic aneurysms (type IIb) were treated by endovascular graft exclusion in the department of cardiovascular surgery of second medical school of Jinan University. Contrast enhanced CT scans were done during the follow-up study. Results Eight powerlink stent grafts were implanted successfu1ly in 8 patients. 12 Zenith AAA Endovascular Grafts were implanted successfu1ly in 12 patients. During the 10~65 months follow-up period, the loca-tions and shapes of the stent-graft were stable in all patients. No displacement occured. TypeⅡendoleakage occurred in 3 cases, which automatically ceased 6 months after the procedure. No other complications occured. Conclusion Endo-vascular graft exclusion may be efficacious and safe in therapy of typeⅡb infrarenal abdominal aortic aneurysms.
