title: Clinical experience with everted cervical vein as patch material after carotid endarterectomy.
abstract: OBJECTIVE
  The aim of this study was to evaluate the clinical efficacy of everted cervical veins used as patches after carotid endarterectomy.
  
  
  METHODS
  A prospective nonrandomized comparative analysis was performed on patients with either everted cervical veins or saphenous veins as patches after carotid endarterectomy. Two hundred ninety-six patients underwent 329 carotid endarterectomies during an 8 1/2-year period (1987 to 1995). Saphenous vein patches were used in 125 (38%) cases and everted cervical veins in 167 (51%). These two groups were compared clinically and by sonographic surveillance. The mean follow-up of patients in this study was 27 +/- 11 months.
  
  
  RESULTS
  No significant differences were noted regarding postoperative morbid events between the everted cervical and saphenous vein patch groups. Even at 5 years the percentage of patients without stroke for both groups exceeded 95%. Duplex surveillance studies also showed comparable percentages of recurrent moderate (50% to 69%) and severe (70% to 99%) stenosis, 5.6% and 6.9%, respectively, for everted cervical vein and 5.4% and 6.5%, respectively, for saphenous vein. Cumulative recurrent stenosis-free rates at 5 and 6 years exceeded 82% for each of the patch study groups.
  
  
  CONCLUSIONS
  Based on the results of this study everted cervical veins are useful adjuncts to carotid endarterectomy, when patch angioplasty is necessary or desirable. Their performance is comparable to that of saphenous veins. Cervical veins are usually available, even when the saphenous vein is absent or inadequate. In addition, good saphenous veins can be spared and lower extremity excisions avoided.
