Accumulation of intimal platelets in cerebral arteries following experimental subarachnoid hemorrhage in cats

Abstract

From 2 hours to 23 days following experimental subarachnoid hemorrhage, the accumulation of indium-111-labeled platelets on the intimal surface of the middle cerebral artery was studied in 23 cats. Subarachnoid hemorrhage was produced by transorbital rupture of the right middle cerebral artery. Of the 23 cats, 17 exhibited right middle cerebral artery/left middle cerebral artery radioactivity ratios of >1.25. When these results were compared with those of 12 control cats, 0.001
