BACKGROUND: The aim of this study was to assess the risk factors for the early and late outcome of the surgical treatment of acute @entity1580 . METHODS: From 1983 to 2000, a total of 130 @entity1 underwent operation for acute @entity1580 . Extent of distal aortic resection included ascending aorta in 19 @entity1 (15%), hemiarch in 29 (22%), and total arch in 82 (63%). In all, 31 preoperative and perioperative variables were analyzed using univariate and multiple logistic regression models for independent predictors of in-hospital mortality and risk of late reoperation. After excluding in-hospital deaths, risk factors for late @entity204 were analyzed by Cox proportional hazard analysis. RESULTS: In-hospital mortality was 19.2% (25 of 130 @entity1 ). Multivariable analysis indicated that renal/mesenteric @entity63 and shock were independent predictors of in-hospital @entity204 . At 10 years, the actuarial survival rate including in-hospital mortality was 70.9% +/- 4.7%, and the reoperation event-free rate was 73.5% +/- 5.7%. Aortic valve resuspension was an independent predictor of proximal aortic reoperation, whereas nonresection of intimal tear and younger age were independent predictors for distal aortic reoperation. @entity1030 was the only independent predictor for late @entity204 . CONCLUSIONS: @entity1 ' preoperative dissection-related complications and comorbidities significantly affect early and late survival rates after surgical treatment of acute @entity1580 .
