We present our 12-year experience with surgical treatment of @entity439 of the thoracic aorta in a high-risk @entity1 population. Of 52 @entity1 with @entity439 , 36 @entity1 , aged 19 to 80 years, had operation. In 24 of the 36, there were three or more associated major disease processes, such as chronic @entity3617 , @entity101 @entity65 , @entity886 , @entity66 , @entity1028 , and @entity453 . Eight @entity1 with acute type A (ascending aorta) and seven with acute type B (descending aorta) @entity439 had emergency repair, with survival in four and seven, respectively. All @entity1 with chronic type A or B @entity439 had elective repair, and all @entity1 with acute or chronic type @entity439 had surgical treatment. Four @entity1 with acute type A and two with acute type B @entity439 had elective operation, with survival in three and one, respectively. Nine @entity1 with chronic type A and six with chronic type B @entity439 had elective operation, and all survived. Twelve @entity1 with chronic type B @entity439 did not have operation, and all were alive at early follow-up. Mortality for @entity1 having acute type @entity439 requiring emergency operation was greater than that after elective repair of acute or chronic type @entity439 . Short-term survival for chronic type B @entity439 was similar whether the @entity1 was treated medically or surgically.
