Perioperative Risk Factors for Hospital Mortality in Patients with Acute Type A Aortic Dissection
Background: We investigated to determine risk factors for hospital mortality following surgery for acute type A aortic dissection (AAAD).
Method: Between January 1997 and December 2006, 243 consecutive patients with AAAD (127 men, 63 ± 11 years,) underwent emergent surgery at our hospital. Surgical procedures included hemiarch replacement (n = 204) and total or partial arch replacement (n = 31). Concomitant procedures included CABG (n = 17), aortic root replacement (n = 8), and aortic valve replacement (n =3). Clinical data (30 variables) of these patients were analyzed retrospectively to determine independent risk factors for hospital mortality.
