A 26-year-old man with mild coronavirus infection (COVID-19) was presented with left lower limb ischemia. The acute thromboembolism was found in the terminal aorta, bilateral iliac and popliteal arteries. Repeated embolectomies were performed three times in addition to surgical fasciotomy of the lower extremity because of re-occlusion. However, he was complicated with toe necrosis and paralysis. Additional percutaneous angioplasty to the bilateral popliteal and calf arteries were performed to prevent toe amputation. In the present study, We experienced a case of arterial thrombosis in mild COVID-19 patient, even though he is young and without significant atherosclerosis or congenital coagulopathy. In a literature search, we also found reports of lower extremity arterial thromboembolism even in mild cases of COVID-19.
