Clinical effect of abdominal aortic aneurysm endografting: 7-year concurrent comparison with open repair.

摘要: Objective We compared the effectiveness and clinical outcome of open repair versus endovascular aortic aneurysm (EVAR) in achieving prevention abdominal (AAA)–related death graft-related complications. Methods Over 7 years from 1997 to 2003, 1119 consecutive patients underwent elective treatment infrarenal AAAs, 585 with 534 EVAR. Patients were regularly followed up at 1, 6, 12 months, every 6 months thereafter, EVAR group, 3 yearly thereafter after repair. Preoperative, intraoperative, follow-up data stored a prospective database. Results Median was similar 2 groups: 33 (interquartile range [IQR], 13-50 months) group vs 35 (IQR, 15-54 group. older than group: 73 72 ( P = .04). There statistical significant differences between respect AAA median diameter (52 mm 56 mm), coronary disease rate (46% 37%; .001), pulmonary (56% 38%; .001) major morbidity 9.1% (49 patients) 18.6% (109 patients; .008). Kaplan-Meier survival estimates 84 67.1% 66.9% NS). At same interval risk for secondary procedures 49.4% 7.1% Of 11 variables analyzed logistic analysis, surgery (hazard ratio [HR], 11; 95% confidence [CI], 2.5-54.2; .002), American Society Anesthesiologists IV score (HR, 7.1; CI, 2.7-18.8; .0001), age 1.06; 1.04-1.13; .04) positive independent predictors perioperative mortality. Conclusion Our suggest that maximum years, who undergo show lower late aneurysm-related mortality younger substantially healthier aneurysms treated The higher need did not affect superiority overall performance early intervals.
