Abstract

A 75-year-old male patient without any significant medical and habitual risk factors for acute atherosclerosis obliterans except for hypertension was diagnosed with coronavirus disease 2019 with dyspnea, coughing, and mild fever. After a week of hospitalization, he complained of right foot pain and numbness. The symptoms were aggravated during the next week, resulting in a complete toe color change and loss of dorsalis artery pulse. Enhanced 3-dimensional computed tomography angiography revealed thrombus formation in the right common iliac artery and a loss of blood flow below the popliteal artery on both sides. The patient underwent percutaneous balloon angioplasty with stent insertion followed by medical therapy for anticoagulation. The clinical symptoms immediately were improved after the intervention, but the great toe necrosis was not recovered. Finally, amputation of the great toe was performed.

고혈압 이외에 급성 폐쇄동맥경화증의 내과적 위험요소가 없던 75세 남자 환자가 경한 발열을 동반한 기침, 호흡 곤란으로 내원하여 코로나바이러스감염증-19 진단을 받았다. 격리입원 치료를 시작한 지 1주일째에, 우측 족부의 동통 및 저린감을 호소하기 시작하였으며, 그 다음 1주일 동안 서서히 한랭감, 전족지의 색깔 변화와 족배동맥의 소실이 나타나게 되었다. 하지 혈관조영 3차원 컴퓨터 단층촬영 검사에서 좌, 우측 모두에서 슬와동맥 이하로 전, 후경골 동맥 및 비골동맥의 혈류가 관찰되지 않았으며, 우측 총장 골동맥 내부에 혈전이 생성되어 있는 모습을 확인할 수 있었다. 우측 하지에 대하여 경피적 풍선 혈관 성형술 및 스텐트 삽입술, 항응고제 투여를 시행하였으며, 시술 직후부터 우측 족배동맥의 맥박이 온전히 촉지되고, 호소하던 한랭감이 개선되었음을 확인하였다. 혈류가 개선되었음에도 불구하고 우측 족무지의 괴사는 회복되지 않아 결국 족무지 절단술을 시행하였다.
