Treatment and management of acute venous thromboembolic disease.

摘要

Venous thromboembolic (VTE) disease consists of deep vein thrombosis and/or pulmonary embolism. Either low molecular weight heparin given subcutaneously or unfractionated heparin administered intravenously are used for the initial treatment. Simultaneously, warfarin therapy is initiated. Thrombolytic therapy plays a limited role. Following the initial heparin treatment, anticoagulation clinics provide an excellent means of monitoring the oral anticoagulation. Patient education is important and patients should be well versed in the basic features of oral anticoagulation. The duration of oral anticoagulation is dependent on a number of factors including the presence of inherited risk factors, bleeding risk and patient reliability. Residual thrombus in the affected vein may indicate the need for prolonged anticoagulation. The low intensity oral anticoagulation (INR 1.5-2.0) is useful in preventing recurrent thrombosis following the initial treatment period with full intensity oral anticoagulation.
