Low molecular weight heparin versus unfractionated heparin in cerebral venous sinus thrombosis: a randomized controlled trial
European Journal of Neurology, 04/06/2012
Low molecular weight heparin resulted in significantly lower hospital mortality in cerebral venous sinus thrombosis (CVST) compared to unfractionated heparin (UFH). Methods Consecutive patients with CVST diagnosed on the basis of MR venography (MRV) who was free of bleeding diathesis, malignancy, hepatic or renal failure were prospectively enrolled. History, clinical findings and risk factors were evaluated. MRI and MRV findings were recorded. The patients were randomized to LMWH and UFH groups for 14 days followed by oral anticoagulant. The hospital mortality and 3 months outcome as assessed by Barthel index (BI) score were noted. Results
32 patients received UFH and 34 received LMWH. The baseline demographic, clinical and radiological parameters were similar in both the groups. Six patients died and all were in UFH group (P = 0.01). At 3 months, insignificantly higher number of patients recovered completely in LMWH compared to UFH group (30 vs. 20). There was no serious side effect needing withdrawal of drugs except one was withdrawn from UFH because of heparin-induced thrombosis.
