[Initial management of venous thromboembolism].
The initial management or venous thromboembolism (VTE) corresponds to the first 3 months of treatment. Pulmonary embolism (PE) are mostly hospitalized. Serious PE associated with hemodynamic instability has to be admitted in intensive care unit due to the need for fibrinolytics. PE without any risk factor for VTE recurrences or death could be followed as outpatient. Conversely, deep vein thrombosis (DVT), including proximal DVT are not hospitalized with the xception of patients with serious risk factors. The therapeutic strategy is identical between DVT and PE treatment with an acute phase with either parenteral anticoagulants, especially low molecular weight heparins or fondaparinux, or by an intensive dose of direct oral anticoagulant such as rivaroxaban or apixaban. Then maintenance therapy has to be prescribed either with vitamin K antagonists with overlapping parenteral anticoagulants for at least 72 hours, or with a maintenance dose of apixaban or rivaroxaban.
