Is venous patch grafting after carotid endarterectomy able to reduce the rate of restenosis? Prospective randomized pilot study with stratification

Abstract

Many studies have already demonstrated that the restenosis rate after carotid endarterectomy is greater as expected since ultrasound examination has become a routine procedure after endarterectomy. The purpose of our randomized study is to compare the rates of restenosis with two methods of carotid endarterectomy--direct suturing and autologous vein grafting. Sofar restenosis are found after endarterectomy and direct suturing. Different possible causes for restenosis are discussed. We hope to inform soon if patching with the autologous vein is the best method in order to prevent early restenosis after CEA.
