Abstract
Among our patients with ruptured intracranial aneurysms 149 were managed pre-operatively with a combination of tranexamic acid (AMCA), 3 gm daily, and aprotinin at an average of 400000 KIU (Kallikrein inactivating units) daily. Antifibrinolytics were started within three days of the last haemorrhage, and continued for at least six days. The first 91 cases, managed in the years 1971 to 1980, have been evaluated retrospectively. The remaining 58 patients were managedin the period 1981-1985 and carefully watched for possible complications of treatment. No significant differences were noted in the results of patients managed either before or after 1981. The rate of recurrent SAH (10%) was lower than the natural history of aneurysmal SAH. Satisfactory inhibition of fibrinolysis was documented in the CSF collected at the time of operation in 15 patients. This, as well as our previous suggestions that the combination of low-dose AMCA and aprotinin might carry a lesser risk of causing ischaemic complications and hydrocephalus than the conventional antifibrinolytic treatment, might stimulate future studies on fibrinolysis in SAHFile | Dimensione | Formato | |
