Femoral Arterial Thrombosis in a Young Adult after Nonsevere COVID-19

Introduction: Few cases of arterial thromboembolisms have been reported after novel coronavirus disease 2019 (COVID-19) in case of severe infection or in elderly patients. We report a case of femoral arterial thrombosis in a young patient after nonsevere infection. Case description: A common femoral artery thrombosis extended in the first third of superficial and profunda femoral arteries associated with tibial posterior and popliteal artery thrombosis was diagnosed in a 24-year-old man complaining of right lower limb pain for one month. The evolution was good after anticoagulation and antiaggregant treatments and thrombectomy. Etiologic assessment was negative except for nonsevere COVID-19. Discussion: COVID-19 accesses host cells via angiotensin-converting enzyme 2 protein, abundant in the lungs, which is also expressed by endothelial cells and is associated with important inflammatory syndrome and coagulopathy, leading to vascular lesions. Thrombosis prevalence is not fully established and seems to be higher in case of major inflammation and in the intensive care unit (ICU). Arterial thromboembolisms are described in many vascular territories, each time in elderly patients, or in case of severe infection. We described a femoral arterial thrombosis in a young patient with negative etiological assessment except nonsevere COVID-19. Treatment consists in anticoagulation and antiaggregant drugs and thrombectomy. Preventing venous thromboembolism treatment is recommended in case of severe infection or in the ICU, but there is no clear recommendation for arterial thromboembolism prevention. This case should lead us to be very careful of the arterial event risk even if the infection is nonsevere and the patient is young.
