Arterial Occlusion and Acute Limb Ischemia Induced Acute Deep Venous Thrombosis in COVID-19 Patients
Coronavirus disease 2019 (COVID-19) is a viral respiratory tract infection that is responsible for various thrombotic events in major blood vessels in the human body, especially deep vein thrombosis (DVT) and pulmonary embolism. [1]. These thromboembolic events are thought to arise from an immune and pro-inflammatory response that results in the production of procoagulation factors that are responsible for vascular injury. Despite the predominant venous etiology, rare reports now implicate COVID-19 in adverse arterial events such as arterial thrombosis that can lead to acute limb ischemia (ALI). [1]. ALI is an emergent vascular event that results in decreased limb blood flow and subsequent tissue hypoperfusion [2].
