ABSTRACT
OBJECTIVE:
Antifibrinolytic treatment after aneurysmal subarachnoid hemorrhage has been shown to have no significant effect on outcome since a reduction in the rate of rebleeding was offset by an increase in the incidence of hydrocephalus and ischemic events. As the results of early aneurysm surgery and a change of strategy in the intensive medical treatment, outcome in patients with cerebral ischemia has been improved. On the other hand, rebleeding still remains as a major cause of death. A short course of tranexamic acid(TA) was tried to study its efficacy and safety in reducing the incidence of rebleeding before aneurysm surgery.
METHODS:
A total of 507 patients with ruptured cerebral aneurysm operated within 3 days after the attack from 1990 to 1999 were included in this study. Group A consisted of 302 consecutive patients treated from 1990 through 1995 served as control. Two hundred-five patients in group B were treated with TA from 1996 through 1999. Both groups were evaluated for comparability of demographic and clinical variables including age, Hunt-Hess grade, Fisher grade, aneurysm location, hypertension, day of surgery, and initial hydrocephalus. The relationships of TA with rebleeding, ischemia, and chronic hydrocephalus were also studied.
RESULTS:
There was no significant difference in patient demographics and clinical characteristics between group A and group B. Sixteen patients(5.3%) suffered a recurrent hemorrhage in group A and three(1.5%) in group B(p<0.05). Chronic hydrocephalus requiring a shunt was found in a significantly greater proportion in group B than in group A(p<0.05). The incidence of cerebral ischemia was not elevated in group B compared with group A.
CONCLUSION:
Considering the fact that the reduction of fatal rebleeding outweighed the increased incidence of hydrocephalus, the authors believe that a short course of TA is beneficial in diminishing the risk of rebleeding prior to early surgical intervention.
