BACKGROUND: @entity64 complicates cardiac surgical procedures in a substantial number of @entity1 . The mechanism of @entity64 is predominantly embolic, although hypoperfusion may play a role. The aim of this study was to determine whether radiologic appearances in this population were consistent with an embolic cause. METHODS: We reviewed computed tomographic scans and medical records in 24 @entity1 who @entity64 after cardiac operation. @entity64 was evident at 24 hours in 19 @entity1 (79%). @entity1188 were multiple in 16 and single in 3 @entity1 (group 1). The remaining 5 @entity1 @entity64 beyond 24 hours and had single @entity1188 on computed tomographic scan (group 2). RESULTS: In group 1, 15 @entity1 (79%) had @entity1188 , 4 (74%) had posterior cerebral @entity1188 , 10 (53%) had posterior watershed @entity1188 , and 11 @entity1 (58%) had @entity2500 . The mean number of vascular territories involved was 5.1 (range, 1 to 10). Mobile @entity1856 was present in the ascending aorta or arch in 5 of 9 @entity1 (56%) in group 1. In group 2, @entity64 occurred in close association with @entity2224 in 3 of 5 @entity1 (60%). CONCLUSIONS: In @entity1 with radiologic evidence of @entity1188 , perioperative @entity64 after cardiac operation are typically multiple, and involve the posterior parts of the brain, consistent with @entity11986 . @entity64 may be attributable to cardiogenic @entity887 .
