@entity1 @entity132 @entity548 @entity101 @entity5 @entity1653 @entity1410 @entity86
A series of 4992 intracranial procedures performed over an 11-year period was evaluated for the occurrence of @entity86 . Forty @entity1 (0.8%) experienced @entity86 . Twenty-four @entity548 were intracerebral (60%), 11 were epidural (28%), 3 were subdural (7.5%), and 2 were intrasellar (5.0%). @entity1410 in 33 @entity1 occurred at the operative site, and 7 occurred remote from the operative site. @entity5 was the reason for operation in 56% of the @entity1 developing a clot, and @entity1653 was the most common @entity5 associated with this complication. The use of the sitting position was not associated with an increased incidence of @entity86 . @entity132 and @entity101 seemed to be potential precipitating factors. @entity86 was recognized within 12 hours of operation in 35% of the @entity1 . An altered level of consciousness was the most frequent clinical finding, present in all @entity1 . There was no clear relationship between the time of recognition and the final clinical outcome. Parenchymal clots carried the worst prognosis, accounting for 8 of the 11 deaths and all 7 @entity1 with poor neurological outcome.
