Cryptogenic, embolic stroke-looking backstage

Abstract

Stroke is a common and devastating event and the majority of cases are caused by thromboembolism from the left atrium, left ventricle or left sided valves. This case report describes a case of embolic stroke with the origin of the thrombus from the left inferior pulmonary vein. The importance of this case is twofold. Firstly, it is the fourth case report of pulmonary venous thrombosis, a very rare condition, due to COVID-19 infection and secondly, it focuses attention on the fact that the left atrium is not the most proximal address of arterial thromboembolism—the pulmonary veins are. Thus, it is proposed that a thorough assessment of the pulmonary veins should be done in all cases of arterial thromboembolism.
