Isolated Radial Vein Thrombosis: Upper Extremity Deep Vein Thrombosis in a Patient With COVID-19 Infection

Abstract

In general, upper extremity deep vein thrombosis (DVT) is less common than lower extremity DVT. Among upper extremity DVT cases, most of them are due to secondary causes like indwelling catheters, cancer, surgery, trauma or immobilization by plaster casts, pregnancy, oral contraceptives, and estrogen. Patients with coronavirus disease 2019 (COVID-19) infection are known to have coagulation dysfunction and a high incidence of DVT, mostly in the lower extremities; however, upper extremity DVT has been rarely reported. We present a rare case of upper extremity DVT in COVID-19 infection. A 56-year-old male with no significant past medical history was admitted with acute respiratory failure due to COVID-19 pneumonia. During hospitalization, he developed right upper extremity swelling, and an ultrasonogram showed right radial vein thrombosis. He was initially started on low molecular weight heparin (LMWH) and was discharged on apixaban. Patients with COVID-19 infection who develop DVT are recommended treatment with a direct oral anticoagulant (DOAC) for three months.
