Deep venous thrombosis of the legs after strokes. Part I--incidence and predisposing factors

Forty out of 76 patients (53%) who had suffered a cerebrovascular accident developed deep venous thrombosis of the paralysed leg, as detected with the 125I-fibrinogen technique. A further five also had thrombosis in the non-paralysed leg. A study of many predisposing risk factors provided no help either in elucidating the cause of venous thromboembolism or in identifying patients at risk of DVT as a complication of cerebrovascular accidents.
