A modified suture technique for peripheral arterial cardiopulmonary bypass

Peripheral cannulation for cardiopulmonary bypass is a frequently used technique in minimally invasive cardiac surgery and reoperation. In patients with a small arterial caliber, the purse suture on the femoral artery leads to marked stenosis after decannulation. In order to prevent this condition, we used double parallel U-sutures rather than purse sutures for arterial cannulation. Herein, we present this technique in the light of literature data.
