A prospective study of internal carotid artery plication during carotid endarterectomy: Early clinical and duplex outcome

Objective: internal carotid artery (ICA) plication prevents kinking and sec ures the distal intimal step following carotid endarterectomy (CEA). The ai ms of this prospective study were to quantify the proportion of patients in whom plication might be beneficial and determine whether plication is asso ciated with an increased incidence of early restenosis and a reduction in p ostoperative thromboembolic complications. Methods: analysis of a prospectively gathered computerised database. Results: between 1 November 1992 and 31 December 1997, 228 consecutive CEAs were performed in 213 patients, of which 84 (37%) in 79 patients were plic ated. Sixty endarterectomy sites have been examined by duplex ultrasonograp hy at a median of 5 (range 1-44) months postoperatively. No abnormality was detected in 52 (87%), six (10%) had restenosis of <50% and two (3%) resten osis of 50-75%. All were asymptomatic. Three patients (3.6%), one of whom d ied, had an intraoperative neurological event and one patient (1.2%) had a postoperative cerebral haemorrhage. No patient suffered ICA thromboembolism . During the same time period 144 non-plicated CEAs were performed in 134 p atients. Of these, one (0.7%) had an intraoperative and five (3.5%) had a p ostoperative neurological event. Five of these sir complications were due t o ICA thromboembolism. There teas no mortality in the non-plicated group. Conclusion: ICA plication can be used to prevent kinking, secure the distal intimal step, has not, to date, been associated with increased early reste nosis rate and has avoided postoperative ICA thromboembolism.
