Basic Surgical Technique Vein patch

In this demonstration, a graft will be sutured on to an elliptical opening in a section of porcine aorta. A primary closure of this ellipse would result in significant narrowing of the diameter of the vessel. A synthetic patch will therefore be used to close the opening.
