The spread of the new SARS-CoV-2 infection, now classified as COVID-19, has become global. The physician who treats patients with COVID-19 face daily new serious problems. One of them is a high prevalence of venous thromboembolic complications, especially in the group of patients with a severe course of the infectious process. Current recommendations allow an empirical approach to prescribing anticoagulation in the case of a reasonable suspicion on the pulmonary embolism/deep vein thrombosis, if the assumed waiting period for visualization is >4/24 hours, respectively. The use of prophylactic doses of low-molecular-weight or unfractionated heparin or fondaparinux is mandatory for all COVID-19-positive inpatients throughout the entire period of hospitalization. If there are the absolute contraindications to anticoagulation, it is recommended to use compression therapy or to perform vena cava filter implantation . Most patients with the confirmed COVID-19-associated venous thromboembolism (VTE) or those with its reasonable suspicion should be prescribed a full treatment dose of anticoagulant. In ambulatory conditions for secondary long-term thromboprophylaxis the preference should be given to direct oral anticoagulants. Patients who had a ≥3-fold elevation of D-dimer level upon admission should continue the therapeutic anticoagulation after discharge. This literature review summarizes the latest recommendations on prevention, diagnosis, and treatment of COVID-19-associated VTE. Further research should focus on developing optimal management strategies for both inpatients and outpatients with COVID-19-associated venous thromboembolism (VTE ).
