Venous thrombo-embolism is a common complication in patients with acute ischaemic stroke. Without prophylaxis, deep vein thrombosis occurs in 60-75% of patients with dense hemiplegia, usually in the paralyzed limb, and 1-2% suffer fatal pulmonary embolism. Orgaran (Org 10172, low-molecular-weight heparinoid) has been evaluated for the prevention of deep vein thrombosis in patients with acute ischaemic stroke in two studies. In a double-blind study, 75 patients were randomized to receive Orgaran (50 patients) in a loading dose of 1,000 anti-Xa units intravenously followed by 750 anti-Xa units subcutaneously 12-hourly or placebo (25 patients). Deep vein thrombosis occurred in 2 of 50 (4%) in the Orgaran group and 7 of 25 (28%) in the placebo group (p = 0.005). The corresponding rates for proximal deep vein thrombosis were 0 and 16%, respectively (p = 0.01). There was one major haemorrhage in the treated group and one minor haemorrhage in the placebo group. In the second study, the safety and efficacy of Orgaran was compared with unfractionated heparin in the prevention of deep vein thrombosis in a double-blind randomized trial. Eighty-seven patients with marked lower limb paralysis secondary to stroke were randomized to receive Orgaran (45 patients) in a dose of 750 anti-factor Xa units subcutaneously 12-hourly or unfractionated heparin (42 patients) in a dose of 5,000 units subcutaneously 12-hourly. Venous thrombosis occurred in 4 of 45 (8.9%) of the Orgaran group and 13 of 42 (31%) in the unfractionated heparin group (2p = 0.014). The corresponding rates for proximal vein thrombosis were 4.4 and 11.9%, respectively (2p = 0.255).(ABSTRACT TRUNCATED AT 250 WORDS)

Deep vein thrombosis (DVT) in hemiplegic patients mainly affects hemiplegic limbs, DVT can also occur only in healthy limbs, and some hemiplegic patients have DVT in both limbs. Characteristics and risk factors of DVT in hemiplegic, healthy, and bilateral limbs are unknown. To describe the proportion, risk factors, extent, and timing of DVT in hemiplegic, healthy and bilateral limbs. A 10-year retrospective review of consecutive patients was performed. DVT affected hemiplegic limbs in 34 (62%), healthy limbs in 11 (20%), and was bilateral in 10 (18%). DVT was more likely to develop in healthy limbs of hemiplegic patients without surgery (odds ratio (OR) 0.022; 95% confidence interval (CI) 0.001-0.922), and without diabetes (OR 0.023, 95% CI 0.001-0.853). Among the veins at the level of which DVT occurred, intermuscular veins represented 20 (45%) in hemiplegic, 5 (37%) in healthy, and 6 (74%) in bilateral limbs. The median time that DVT occurred after hemiplegia onset was 18 days (interquartile range [IQR] 9-79) in hemiplegic, 17 days (IQR 10-56) in healthy, and 21 days (IQR 8-27) in bilateral limbs. Early and effective prevention of DVT after surgery and optimal management of diabetes may reduce the risk of DVT in bilateral limbs. It's important to prevent proximal extension of calf vein DVT. DVT prophylaxis should be started early and continued for at least 3 weeks after hemiplegia onset.
