Twelve-Month Patency With the PAS-Port Proximal Connector Device: A Single Center Prospective Randomized Trial

This prospective randomized study demonstrated excellent short and midterm patency in both the hand-sewn and PAS-Port grafts. The PAS-Port system allowed for the rapid, safe, and effective creation of a proximal anastomosis without the need to clamp the aorta. Based on this study we consider this product a valid alternative for proximal anastomosis, especially in patients with severe aortic disease, to avoid side clamping of the aorta.
