Controversy exists regarding aortic root reconstruction in the management of acute @entity1580 (AAD). One hundred fifty-four @entity1 (mean age 56.9    11.3 years) with AAD had surgical repair between 1996 and 2007. Group 1 (n = 110) required no aortic root surgery. Seventy-one @entity1 had ascending aortic replacement. The aortic valve was repaired in 37 @entity1 (34%) and replaced in one. Group 2 (n = 44) had aortic root surgery. Thirty-four @entity1 had composite root replacement, and seven had a valve-sparing root replacement. Root reconstruction and separate valve replacement was accomplished in three. Hemiarch replacement was included in 39 (35.4%) Group 1 @entity1 and in 12 (27.9%) Group 2 @entity1 . Forty-nine of the 154 @entity1 presented in @entity1455 . Multiple risk factors for operative mortality were analyzed. The overall operative mortality was 9.7 per cent: 11 per cent for Group 1 and 6.8 per cent for Group 2 (P = NS). By multivariate analysis, @entity1457 (P = 0.03, odds ratio [OR] = 5.48), postoperative @entity943 (P = 0.002, OR = 4.62), and packed red blood cell transfusion (P = 0.002, OR = 1.15) were independent predictors of @entity204 . Prompt surgical treatment of AAD before @entity1455 ensues can improve the outcome of @entity1 . When indicated, aortic root surgery can be performed without increased mortality and morbidity.

Aortic root surgery does not increase the operative risk of acute XXXX .
