title: Double-blind randomised trial of Org 10172 low-molecular-weight heparinoid in prevention of deep-vein thrombosis in thrombotic stroke.
abstract: In a double-blind, randomised trial Org 10172 low-molecular-weight (LMW) heparinoid was compared with placebo in the prevention of deep-vein thrombosis in patients with acute thrombotic stroke. Prophylaxis was started within 7 days of the onset of stroke with a loading dose of 1000 anti-factor-Xa units intravenously followed by a fixed dose of 750 anti-factor-Xa units twice a day subcutaneously; it was continued for 14 days or until hospital discharge, if earlier. 50 patients were randomised to receive Org 10172 and 25 to receive placebo. All patients underwent surveillance with I125-fibrinogen leg scanning and impedance plethysmography. Venography was carried out if either test became positive. Venous thrombosis occurred in 2 of 50 patients (4.0%) given Org 10172 and 7 of 25 patients (28.0%) given placebo (p = 0.005); the corresponding rates of proximal-vein thrombosis were 0% and 16%, respectively (p = 0.01). There was one major haemorrhage in the Org 10172 group and one minor bleed in the placebo group.
