Brachial Artery Thrombosis in a Covid-19 Positive Patient with Thoracic Outlet Syndrome.

Severe coronavirus disease 2019 (COVID-19) has been complicated by coagulopathy and thrombotic events including venous thromboembolism, pulmonary embolism, and arterial thrombus at a rate higher than has traditionally been seen with sepsis-induced coagulopathy or disseminated intravascular coagulation leading most centers to treat hospitalized patients with prophylactic anticoagulation. We present a case of a patient with thoracic outlet syndrome who presents with brachial artery thrombosis in the setting of infection with COVID-19. Both thoracic outlet syndrome and COVID-19 infection are independently associated with increased risk of thrombotic events. The induced hypercoagulable state from COVID-19 infection may result in acute arterial thrombosis in patients with predisposing anatomic differences consistent with thoracic outlet syndrome.
