肾下型腹主动脉瘤腔内隔绝术与传统手术对肾功能影响的比较研究

Affects upon renal function after conventional surgery or endovascular graft exclusion for infrarenal abdominal aortic aneurysms: A comparative investigation

目的 对比肾下型腹主动脉瘤 (AAA)腔内隔绝术 (EVE)与传统手术 (CS)对肾功能的影响。方法 回顾 1997年 3月至 2 0 0 2年 3月间实施的 15 7例肾下型AAA手术 ,其中EVE组 115例 ,CS组 4 2例 ,分析比较两组手术前后血肌酐、血尿素氮的变化情况。结果 CS组术后血肌酐、血尿素氮较术前明显升高 ,并发生急性肾衰 1例 ,而EVE组手术前后两指标无显著差异。结论 EVE对肾下型AAA患者肾功能的影响明显小于CS。

Objective To assess and compare the affects upon renal function after endovascular exclusion (EVE) or conventional surgery (CS) for infrarenal abdominal aortic aneurysms(IAAA). Methods The records of 157 consecutive patients with IAAA from 1997 to 2002 were retrospectively reviewed. There were a group of 115 patients undergoing EVE and a group of 42 patients undergoing CS. The postoperative changes of plasma Cr and BUN with EVE and CS were analyzed respectively and compared. Results The plasma Cr and BUN were significantly increased in the group of CS postoperatively, but no significant difference were shown before and after endovascular repair was discovered in the group of EVE. Moreover, there was a case with acute renal failure in CS group. Conclusion The affects upon renal function with EVE are much less than CS for IAAA patients.
