COVID-19 is a contagious infectious disease, which quickly spreads worldwide, whose clinical presentation includes from mild flu-like symptoms to pneumonia and severe acute respiratory syndrome. The severe presentation of the disease can affect different organs and systems. Coagulopathy has been associated with a worse clinical outcome, with manifestations such as pulmonary embolism and systemic arterial thrombosis. Thromboelastometry has been used to identify hypercoagulability in early stages of disease. We report the case of a 59-year-old woman with COVID-19 infection complicated by pulmonary embolism and acute arterial thrombosis associated with critical lower limb ischemia requiring amputation. This report showed a case of thrombotic complication in patient with infection caused by novel coronavirus 2019 whose thromboelastometry allowed the early identification of hypercoagulability pattern. This is a single case report and the use of thromboelastometry should be further evaluated in large prospective cohort studies.
