Eversion endarterectomy of the internal carotid artery: midterm results of a new technique.
A new eversion endarterectomy technique was used in 65 internal carotid artery reconstructions in 56 patients. The original features of the technique include a complete oblique transection of the internal carotid artery distal to the lesion and eversion endarterectomy through a longitudinal incision of the common carotid and external carotid arteries. The mean age of the patients was 68.2 +/- 7.8 years. Seventy-three percent of the patients had hypertension and 45.5% had coronary heart disease. Fifty-four percent experienced neurologic symptoms (transient in 36%, reversible in 6%, and permanent in 11%). Operations were performed under general anesthesia. An indwelling shunt was inserted whenever routine stump pressure was < 50 mmHg. There were no neurologic complications but one patient died of a compression hematoma of the neck, for a combined mortality and morbidity rate of 1.5%. Arteriograms were obtained from all patients on day 5 and showed complete restoration of normal anatomy in all cases and thrombosis of the external carotid artery in one. During a mean follow-up of 27 +/- 4.7 months no strokes were observed. Follow-up duplex scans showed no hemodynamically significant restenoses. Eversion endarterectomy is a reliable alternative to other reconstruction procedures of the internal carotid artery.
