Does carotid eversion endarterectomy and reimplantation reduce the risk of restenosis?
Two hundred twelve eversion endarterectomies of the internal carotid artery and reimplantation in the common carotid artery were performed between January 1985 and July 1990. A total of 206 patients with stenosis of 75% or more and with redundancy and tortuosity of the internal carotid artery underwent this procedure. Cumulative mortality and neurologic morbidity were 2.4%. Forty patients died during the course of follow-up, seven of neurologic causes (17.1%). Duplex scans of 107 operated carotid arteries were obtained an average of 27.1 months after surgery. Restenosis of > 50% was encountered in three patients (1.9%), two asymptomatic patients (1.3%) with > 75% restenosis and one symptomatic patient with occlusion (0.6%). These results contrast with a 13.5% rate of restenoses > 50% (including 5.9% of restenoses > 75% and 1.7% occlusions) observed after 156 consecutive endarterectomies performed and closed by direct suture by the same surgical team in 1987 at a mean follow-up of 44 months. We believe that this technique can be used more often because the the operative and long-term risks are not any greater than those of the other methods of carotid revascularization. Eversion endarterectomy associated with reimplantation is especially indicated when the internal carotid artery is elongated, is < 4 mm wide, and occurs in women.
