What is it?
Vessel anastomosis is a critical technique for vascular and cardiovascular surgeons. The primary goal of an anastomosis is to connect two vessels, without causing early or late complications, which can be brought on by the trauma of needle perforation through the vessel.
Needle hole bleeding is a potential result of such trauma, and can become problematic in very long suture lines, in calcified or fragile vessels, in situations of very high pressure, or when synthetic graft material is used.(1)
Needle Hole Bleeding
While vessel trauma and post-anastomotic bleeding are influenced by various factors, it has been recognized that choice of suture material and needle can influence the rate of bleeding from needle holes. One of these critical factors is the ratio between the diameters of the needle and the suture. As the needle-to-suture diameter ratio approaches 1:1, the suture that is left behind in the anastomosis will more completely fill the hole made by the needle.(1)
PROLENE® Polypropylene Suture with Hemo-Seal™ Technology
PROLENE Suture with Hemo-Seal technology has a unique design that tapers down the suture at the needle attachment site, allowing a thinner needle to be attached. In a pre-clinical model, PROLENE Suture with Hemo-Seal technology was shown to reduce the needle hole leak rate by 67% compared to the standard PROLENE suture and by 59% compared to ePTFE Suture.(2)
