COVID-19 is a contagious respiratory infection. This disease affected the healthcare system globally due to its complications related to vascular morbidity and mortality. There is a pathophysiological connection between COVID-19 and deep vein thrombosis (DVT). The blood hypercoagulability, venous stasis, and endothelial dysfunction in patients with COVID-19 have been associated with a higher risk of developing DVT. In this systematic review, 15 studies were selected to determine if COVID-19 can be taken as an independent risk factor for DVT. The search was done to determine studies analyzing the incidence of DVT in patients with COVID-19. The studies chosen were observational studies between 2020 and 2025.
