Carotid endarterectomy after a XXXX : reduction in long-term neurologic deterioration.

@entity1 @entity64 @entity101 @entity6 @entity66 @entity51 @entity299 @entity204
The merit of carotid endarterectomy for @entity1 who previously have sustained a @entity64 remains controversial. Between January 1976 and December 1983, 118 @entity64 @entity1 with mild to severe permanent @entity51 were evaluated. Fifty-nine @entity1 were managed nonoperatively and 59 operatively. Both cohorts were similar in age and sex distribution, incidence of @entity101 (69%), @entity6 (25%), and @entity299 (39%). In the long-term follow-up (medical cohort average was 44.1 +/- 5.0 months; surgical cohort average, 41.8 +/- 3.7 months) the overall survival rate was comparable, that is, there were nine medical @entity204 and eight surgical @entity204 . However, there was a significant difference in the development of new @entity51 . Twelve of the 59 unoperated @entity1 had new @entity51 and three @entity1 died at 12, 36, and 48 months as a result of a recurrent @entity64 . New @entity51 developed in only two of the 59 surgical @entity1 and there were no @entity64 -related @entity204 . When the cumulative probability of remaining free from recurrent deficits was examined in the surviving @entity1 at 6 years, all of the @entity1 in the operated group remained free from recurrent deficits, whereas only 58% of the @entity1 in the unoperated group were free of new @entity51 (p = 0.02). These data suggest that @entity64 @entity1 with fixed mild to moderate @entity51 and with @entity66 may be protected from recurrent neurologic complications by carotid endarterectomy.
