Perioperative risk factors predict one-year mortality in patients with acute type-A aortic dissection.

ABSTRACT:

Objective

The goal of this study was to analyze perioperative risk factors to predict one- year mortality after operation for acute type A aortic dissection (AAD).

Methods

A total of 121 consecutive patients undergoing Stanford type A AAD surgery in Beijing Anzhen Hospital were enrolled. Preoperative clinical and laboratory data from patients were collected.

Results

Multivariable Cox regression analysis showed that significant factors associated with increased one-year mortality were elder age (year) (hazard ratio (HR) 1.0985; 95% confidence interval (CI) 1.0334-1.1677), intraoperative blood transfusion ≥2000 mL (HR 8.8081; 95% CI 2.3319-33.2709), a higher level of serum creatinine (μmol/L) at postoperative one day (HR 1.0122; 95% CI 1.0035-1.0190) and oxygenation ind
