[Hormone replacement therapy and venous thromboembolism].
Venous thromboemboembolism is a multigenic and a multifactorial disease. Several genetic risk factors have been identified: antithrombin, protein C and protein S deficiencies, and molecular defects in factor V gene (factor V Leiden) or factor II gene (G 20210A transition). Retrospective and prospective studies have demonstrated that hormone replacement therapy (HRT) in women is associated with ...
متن کاملSymptomatic venous thromboembolism after total knee replacement.
Chemical prophylaxis is known to reduce the venographic prevalence of deep-vein thrombosis (DVT) after total knee replacement (TKR), but it is uncertain whether this affects the incidence of symptoms. Further analysis depends on the basic epidemiology of thromboembolic symptoms. We therefore studied the pattern of such symptoms in a consecutive series of 1000 patients with primary TKR, with par...
متن کاملVenous thromboembolism and hormone replacement therapy.
There is evidence that postmenopausal women who take hormone replacement therapy develop biochemical hypercoagulability, expressed by increased activity of coagulation enzymes. Such effects are observed whether estrogen is given alone or in combination with progestogens, orally or transdermally. Two recent randomized, double-blind clinical trials have shown that hormone replacement therapy lead...
متن کاملA venous foot pump reduces thrombosis after total hip replacement.
In a prospective, randomised controlled trial, the efficacy of the A-V Impulse System in the prevention of deep-vein thrombosis was investigated in 84 patients who had undergone total hip replacement. The incidence of venographically proven, and clinically significant postoperative deep-vein thrombosis was 40% in the control group and 5% in the treatment group (p less than 0.001). No adverse re...
متن کاملPrevention of venous thrombosis with minidose warfarin after joint replacement.
Without prophylaxis 5-10% of patients having elective hip replacement develop clinically important venous thrombosis and about 5% develop symptomatic embolism, which is fatal in up to 0-5%.' Effective preventive methods exist, but many orthopaedic surgeons do not use them systematically because they tend to be complex, cumbersome, dangerous, or not generally available.' Minidose warfarin (a fix...
