The effect of carotid siphon @entity850 on XXXX rate, @entity204 , and relief of symptoms following elective carotid endarterectomy.

@entity1 @entity850 @entity64 @entity204
It has been suggested that carotid endarterectomy for carotid bifurcation disease may be contraindicated in the presence of carotid siphon lesions. This study was undertaken to assess any difference in @entity64 rate, mortality, or relief of symptoms in @entity1 with and without such "tandem" lesions following elective carotid endarterectomy. Ninety-one bifurcation endarterectomies were performed in 79 @entity1 . The @entity1 were divided into two groups. Group I (44 @entity1 , 47 endarterectomies) had carotid bifurcation @entity850 only; group I (35 @entity1 , 44 endarterectomies) had siphon @entity850 plus bifurcation @entity850 . All @entity1 in both groups who were symptomatic before operation were relieved of their symptoms. In group I there were no intraoperative or perioperative @entity64 , four late @entity64 (8.7%), one operate @entity204 (2.1%), and no late deaths. Group II @entity1 had two intraoperative @entity64 (4.5%), three perioperative @entity64 (6.8%), two late @entity64 (5.1%), four operative deaths (9.1%), and three late deaths (7.5%). Eighteen of the 35 @entity1 in group II had a greater degree of carotid siphon @entity850 than bifurcation @entity850 . In this subgroup, there was one operative @entity64 (5.6%), only perioperative @entity64 (5.6%), one late @entity64 (5.9%), one @entity204 (5.6%), and one late @entity204 (5.6%). None of these differences were statistically significant. Relief of symptoms was the same in @entity1 with and without tandem carotid lesions, and there was no significantly increased risk of @entity64 or @entity204 following bifurcation endarterectomy in @entity1 with tandem carotid lesions.
