Venous thromboembolism, including thrombosis of the deep veins of the legs and embolism to the pulmonary arteries, is uncommon in the general population. The absolute risk of venous thromboembolism in non-hormone therapy users is approximately 1 in 10,000 women. Women taking hormone therapy have a twofold increase in risk for thromboembolic events, with the highest risk occurring in the first... 

Venous thromboembolism (VTE) is one of the most common cardiovascular disorders in the United States. VTE is manifested as deep vein thrombosis (DVT) and pulmonary embolism (PE) resulting from thrombus formation in the venous circulation (Fig. 7-1).1 It is often provoked by prolonged immobility and vascular injury and is most frequently seen in patients who have been hospitalized for a serious medical illness, trauma, or major surgery. VTE can also occur with little or no provocation in patients who have an underlying hypercoagulable disorder.

The WHI demonstrated an increased risk in venous thromboembolic disease in the HRT group (0.34%) compared with placebo (0.16%) (HR 2.11,95% Cl 1.58-2.82). This translates into an NNTH of approximately 555 and 18 more cases of venous thromboembolic events for every 10,000 women treated per year with HRT.3 The risk for deep vein thrombosis also was increased in the ERT arm of the WHI, but pulmonary embolism was not increased significantly.21... 

Venous thromboembolism (VTE) results from clot formation in the venous circulation and is manifested as deep vein thrombosis (DVT) and pulmonary embolism (PE). A DVT is a thrombus composed of cellular material (red and white blood cells, platelets) bound together with fibrin strands. A PE is a thrombus that arises from the systemic circulation and lodges in the pulmonary artery or one of its branches, causing complete or partial obstruction of pulmonary blood flow. 

The risks and benefits of HRT should be carefully assessed on an individual basis. This is particularly important in women with predisposing risk factors, such as a personal or family history of deep vein thrombosis or pulmonary embolism, severe varicose veins, obesity or prolonged bed-rest [2], because HRT increases the risk of venous thromboembolism and stroke. HRT has also been observed to increase the risk of gallbladder disease, breast cancer and endometrial cancer. It is recommended that the minimum effective dose should be used for the shortest period of time, with treatment being reviewed at least once a year [2]. 

The convenience (and cost-effectiveness) of LMW heparin therapy has resulted in widespread changes in practice. Patients with acute venous thromboembolism can be treated safely and effectively with LMW heparin as outpatients. Large-scale studies have demonstrated that outpatient treatment of acute deep vein thrombosis (DVT) with unmonitored body-weight adjusted LMW heparin is as safe and effective as inpatient treatment with adjusted dose intravenous standard heparin. Further trials have confirmed the safety and efficacy of LMW heparin therapy in acute pulmonary embolism and that 80% of imselected patients with acute thromboembolism can be safely treated as outpatients. ... 

Venous thromboembolism (VTE) is a complicating condition responsible for high morbidity and mortality in North America and Europe. This disease commonly is linked to advanced age but has both hereditary and acquired risk factors, such as surgery, any form of trauma, and childbirth, associated with it. It encompasses the conditions of deep vein thrombosis (DVT) and pulmonary embolism. In excess of 60,000 deaths annually are attributed to pulmonary embolism. Preventative therapy consists of the use of two different classes of antithrombotic agents, namely anticoagulants and antiplatelet drugs (1,2). 

A variety of clinical states are associated with thrombosis. The present discussion is limited to a few of the more prominent thromboembolic diseases further Information on this subject may be found in several reviews.3,7-9 The most common clinical states which Involve clot-like, venous thrombi are deep vein thrombosis, particularly as a postsurgical complication, and pulmonary embolism. Anticoagulants such as heparin and the coumarins have been known for years to be effective in the prevention of these types of thrombi and more recent experience has demonstrated the efficacy of fibrinolytic agents such as streptokinase for their dissolution.3,9 Platelet aggregation Inhibitors have only recently been evaluated clinically in the prevention of venous thrombosis. These studies are crucial to the resolution of the controversy as to whether platelets play a vital role in the initiation of venous thrombi.10 There is persistent histological evidence that indicates venous thrombi begin as platelet aggregates.H Myocardial infarction and stroke are...
