Abstract
The study objective is to evaluate the effectiveness and the safety of different cerebrospinal fluid drainage methods and intrathecal fibrinolytic therapy in the prevention of cerebral vasospasm and improving outcomes in patients with massive subarachnoid hemorrhage. Materials and methods. The study was performed on 86 patients with massive aneurismal subarachnoid hemorrhage (Hijdra score >15) who had clipping surgery within 72 h after symptoms onset. We used lumbal drainage in 12 patients (group 1), combined lumbal and cisternal drainage in 24 patients (group 2), lumbal and cisternal drainage with intrathecal fibrinolytic therapy with recombinant staphylokinase in 25 patients (group 3); control group (group 4) included 25 patients with similar clinical and instrumental data. Results. Incidence of unfavorable outcome and symptomatic cerebral vasospasm was 83 and 83 %, respectively (in group 1), 36.8 and 47.4 % (in group 2), 9.1 and 9.1 % (in group 3), 76 and 60 % (in group 4). Conclusion. The proposed intrathecal fibrinolytic therapy with recombinant staphylokinase may be effective and safe to reduce the severity of cerebral vasospasm, improve clinical outcome and lower frequency of normal pressure hydrocephalus after aneurysm rupture.
