 3. femoral endarterectomy with or without patch angioplasty involving the common femoral artery andor profunda andor proximal superficial artery. The index groin may have undergone prior procedures may be inflow or outflow for existing grafts, but the patient must have fully healed from the prior operation. May include patients with concomitant proximal andor distal peripheral vascular intervention. The patch may be autogenous venous or arterial or prosthetic material such as bovine pericardium, dacron or polytetrafluoroethylene PTFE. Bilateral femoral endarterectomies are eligible for enrollment. The right and left groin incision would be randomized to the same dressing which is consistent with routine clinical practice.
