Comparison of outcomes between axillary and femoral artery cannulation for type A aortic dissection surgery

The findings indicate that femoral and axillary arterial cannulation yield similar outcomes in patients with acute type A aortic dissection. The choice of cannulation site should be individualized based on each patient's specific risk factors. Additionally, preoperative hemodynamic instability, the duration of cardiopulmonary bypass (CPB), and a high body mass index (BMI ≥ 30 kg/m²) are independent predictors of operative mortality.
