Pharmacological management of pulmonary embolism

Pulmonary embolism (PE) is a common and potentially severe manifestation of venous thromboembolism. Its management has relied on anticoagulation by vitamin K antagonists (VKA) for the past fifty years. Recently, new alternative drugs have been developed and dramatically modified both the treatment of acute PE and its secondary prevention. Areas covered: This review discusses the contemporary pharmacological treatment for PE, with a focus on anticoagulation options for non-high risk PE. In particular, the advent of direct oral anticoagulants (rivaroxaban, apixaban, edoxaban and dabigatran) and modalities for long-term prevention will be described. Options for anticoagulation for pregnancy-related PE are presented separately. Expert opinion: Direct oral anticoagulants represent the first-line therapy of non-high risk PE, with better risk-benefit ratios compared with VKA due to lower bleeding risks. In specific groups of patients, however, older generations of anticoagulants such as VKA or heparins still play an important role. Multiple alternatives are available for the secondary prevention of PE, with different efficacies in reducing thrombotic risk and bleeding safety profiles

Thromboses veineuses splanchniques

Splanchnic vein thromboses include thrombosis of the portal venous system (including the portal, mesenteric and splenic vein) and hepatic vein thrombosis (also called Budd-Chiari syndrome). They are rare manifestations of venous thromboembolism. These thromboses are frequently associated with local or systemic factors. The therapeutic approach is often complex due to heterogeneity of patients and limited available data in the literature. The cornerstone of treatment is anticoagulation. However, the bleeding risk, related to portal hypertension, should be accurately assessed to individualize the treatment. A multidisciplinary consultation team including several specialists is provided at the University Hospitals of Geneva for the optimal management of those patients

Clinical prognosis of non-massive central and non-central pulmonary embolism: a registry-based cohort study

Whether the localization of non-massive pulmonary embolism (PE) is associated with the short and long-term prognosis of patients remains unknown. Our aim is to characterize associations of non-massive PE localization with risks of recurrent venous thromboembolism (VTE), major bleeding and mortality during and after anticoagulation
