Abstract
This article presents a clinical case of treating arterial thrombosis of the left lower limb against the background of a severe course of a new coronavirus infection. The COVID-19 infection virus appeared more than two years ago, and in addition to the main pathogenetic effect of the virus on the lungs, the systemic nature of the effect on the body as a whole was revealed, including involvement of the hemostasis system. Complications aggravating the course of the disease were identified, such as arterial thrombosis and thromboembolism of the arteries of the lower extremities against the background of anticoagulant therapy, in many cases leading to amputation. This clinical observation demonstrates the burdened course of the disease and a comprehensive surgical approach that allowed the patient’s lower limb and life to be preserved against the background of a new coronavirus infection.
