Abstract
We studied the mechanism of hemorrhagic infarction after acute cerebral embolism in 160 patients by brain computed tomography and angiography. Hemorrhagic infarction during the month after the embolic event was evident in 65 patients (40.6%). Initial angiography a median of 1.5 (range 1-60) days after the event revealed occlusion of the cerebral arteries in 117 of 142 patients (82.4%), and reopening of the vessels was observed in 56 (94.9%) of 59 patients who had follow-up angiography a median of 20 (range 3-47) days after the event. The incidence of hemorrhagic infarction was higher in patients greater than or equal to 70 years old (31 of 61, 50.8%) than in those aged 50-69 years (27 of 72, 37.5%) or less than 50 years (seven of 27, 25.9%) (greater than or equal to 70 vs. less than 50, p less than 0.05). In patients with moderate or large infarcts, hemorrhagic infarction developed in 50.0% or 51.5%, respectively, while in those with small infarcts it developed in only 2.9% (p less than 0.05).
