Background-Currently, the optimal treatment of acute type B aortic dissection remains controversial. The purpose of this study was to report early clinical outcomes of medical management for acute type B aortic dissection. Methods and Results-Between

In our experience, surgical repair of acute type A aortic dissection can be performed in the setting of preoperative stroke with acceptable mortality. Moreover, no worsening of neurologic condition was observed after surgical repair. Immediate surgical repair is warranted even if acute type A aortic dissection is complicated by stroke.

Aortic root enlargement itself does not increase operative risk, although it is most often required among high-risk patients. Surgeons should not be reluctant to enlarge the aortic root to permit implantation of adequately sized valve prostheses.

Biliary disease, hepatic dysfunction, and bowel ischemia after DTA/TAA surgical repairs were associated with an increased mortality. Visceral involvement and preoperative renal insufficiency were risk factors for the occurrence of GI complications.
