title: A prospective study of internal carotid artery plication during carotid endarterectomy: early clinical and duplex outcome.
abstract: OBJECTIVE
  internal carotid artery (ICA) plication prevents kinking and secures the distal intimal step following carotid endarterectomy (CEA). The aims of this prospective study were to quantify the proportion of patients in whom plication might be beneficial and determine whether plication is associated with an increased incidence of early restenosis and a reduction in postoperative 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 plicated. Sixty endarterectomy sites have been examined by duplex ultrasonography 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%) restenosis of 50-75%. All were asymptomatic. Three patients (3. 6%), one of whom died, 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 patients. Of these, one (0.7%) had an intraoperative and five (3.5%) had a postoperative neurological event. Five of these six complications were due to ICA thromboembolism. There was no mortality in the non-plicated group.
  
  
  CONCLUSIONS
  ICA plication can be used to prevent kinking, secure the distal intimal step, has not, to date, been associated with increased early restenosis rate and has avoided postoperative ICA thromboembolism.
