Carotid endarterectomy. Relationship of outcome to early XXXX .

@entity1 @entity64 @entity63 @entity256 @entity850 @entity543
The results following carotid endarterectomy were prospectively evaluated in 134 @entity1 (145 sides) by repeat ultrasonic duplex scanning and clinical evaluation extending for a period of 4 years. There were 107 @entity1 and 27 @entity1 in the study group. The perioperative @entity64 rate was 1.3% and the mortality rate, 0.7%. There were 9 late deaths, of which two were @entity64 related (1.4%). Focal symptoms occurred in 12 @entity1 on the ipsilateral side, six of which were @entity64 (one lacunar). The remaining symptoms developed in the presence of moderate degrees of @entity543 (less than 50%). There were seven @entity1 who had transient @entity63 attacks (TIAs) referable to the operated side, but only two of these were associated with a recurrent high-grade @entity850 . During follow-up 32 (22%) @entity1 had recurrent high-grade @entity850 . Restenosis regressed in seven, giving a persistent rate of 17.1%. The incidence of @entity256 was significantly higher in @entity1 (p less than 0.01). By life-table analysis, @entity256 occurred early, the majority within 24 months. There was no consistent association between the development of symptoms and the occurrence of @entity256 . Therefore, it is concluded that there is no justification for reoperation based on the degree of narrowing observed to prevent subsequent TIAs and @entity64 .
