29,589 | Cost considerations surrounding current and future anticoagulant therapies. | Because the costs of anticoagulation therapy are substantial and the difference between the risks and benefits of this therapy are often narrow, economic analyses are particularly valuable when weighing anticoagulation options. Economic analyses to date suggest that anticoagulation is most effective and results in the ... |
29,590 | Anticoagulation in special patient populations: are special dosing considerations required? | Optimal dosing of low-molecular-weight heparin (LMWH) therapy has not yet been established for patients with morbid obesity or renal insufficiency or for pregnant women. Monitoring of anti-Xa levels appears to be helpful in guiding LMWH dosing in all of these patient groups. Use of fondaparinux in these populations has... |
29,591 | Current and emerging options in the management of venous thromboembolism. | Venous thromboembolism (VTE) is a common disease whose diagnosis is challenging. The best diagnostic approaches combine the patient's pretest clinical probability of disease with D-dimer testing and/or diagnostic imaging. In light of several advantages, low-molecular-weight heparins are now recommended over unfractiona... |
29,592 | Prevention of venous thromboembolism in medical and surgical patients. | Prophylaxis against venous thromboembolism (VTE) should be considered in all hospitalized patients, as VTE is a significant cause of morbidity and mortality in the hospital. Although VTE risk is greatest and VTE prophylaxis is more established in surgical patients, most hospitalized medical patients have one or more ri... |
29,593 | Deep vein thrombosis (DVT) in advanced cancer patients with lower extremity edema referred for assessment. | Lower extremity edema is a common complication in advanced cancer patients, and deep vein thrombosis (DVT) is one among many causes. Clinical signs and symptoms are known to be unreliable, and radiographic investigations are often required in diagnosing DVT. A retrospective chart review was conducted on 46 advanced can... |
