XXXX after carotid endarterectomy.

@entity1 @entity101 @entity548 @entity2806 @entity7975 @entity551 @entity543 @entity1779
A series of 14 @entity1 with @entity1779 after carotid endarterectomy is reviewed. This complication occurred in 0.6% of 2362 consecutive carotid endarterectomies performed at the Mayo Clinic from 1972 through 1986. All @entity548 occurred within the first 2 weeks after operation and were ipsilateral to the side of the operation. Eight @entity1 died, and only two made a good recovery. Significant risk factors are @entity101 and chronic @entity7975 with impaired autoregulation. The "normal pressure-hyperperfusion breakthrough" syndrome was considered to be operative in 12 of the 14 @entity1 . Nine @entity1 had documented hyperperfusion (at least 100% increase of baseline cerebral blood flow) at the time of surgery. In an additional three @entity1 , normal perfusion-pressure breakthrough was inferred by the clinical course and radiological findings, as well as by the absence of alternative explanations. @entity1 at risk for postendarterectomy @entity1779 include those who have a clinical history suggestive of @entity2806 , severe @entity543 with limited hemispheric collateral flow, and postendarterectomy hyperperfusion, as measured by intraoperative cerebral blood flow. To minimize the risk of @entity548 in these @entity1 , strict maintenance of blood pressure at normotensive or even relatively @entity551 levels during the intraoperative and early postoperative periods is advised.
