Vasospasm in response to repeated subarachnoid hemorrhages in the monkey

摘要: ✓ This study investigates the relationship between vasospasm and repeated subarachnoid hemorrhages in 18 monkeys. Sixteen received weekly 4 cc injections of autogenous blood into subfrontal space. The mortality rate for weeks was 6%, 33%, 20%, 37% respectively. over-all 75%. degree did not correlate with morbidity mortality. Vasospasm limited to intradural cerebral vessels diffuse. It never lasted longer than a few hours, late occur, alter occasions “subarachnoid hemorrhage.” Immediate electrocardiogram abnormalities were related height cerebrospinal fluid pressure rise following hemorrhage (injected blood). Pathological examination shown be spasm normal. suggests that increased associated is due cumulative structural damage rath...
