Characteristics and Outcomes in Patients with Acute Aortic Dissection: A Nationwide Registry Study

In this mandatory national clinical registry analysis of acute aortic dissections, in-hospital mortality was 18 percent in 859 patients who underwent repair of type A dissections vs. 52 percent in 298 unoperated-on type A patients, and 13 percent in 122 patients who underwent surgical or endovascular repair of type B dissections vs. 13 percent in 434 unoperated-on type B patients. Unadjusted three-year survival in patients discharged alive was 91 percent after type A dissection repair vs. 78 percent without surgery, and 83 percent after type B repair vs. 77 percent without surgery.
