Experience in treatment of patients with arterial and venous thrombosis with proven COVID-19

Abstract

Background. COVID-19 is represented by a large number of different phenotypes, ranging from asymptomatic progress to the development of severe multiple organ dysfunction syndrome. The mechanisms of development of multiple organ dysfunction syndrome are multifactorial, including hypercoagulation with the formation of blood clots. They are often diagnosed as thrombotic complications with detection of blood clots not only in the veins and pulmonary arteries, but also in the heart and main arteries. An observational study shows that the incidence of venous and arterial thrombosis is as high as 31% in patients with COVID-19 pneumonia. However, large studies have not yet been conducted.Aim. To generalize and analyze our own observations of the clinical course of patients with thrombosis and COVID-19.Methods. The study included 5 male patients who had arterial and venous thrombosis and COVID-19 positive test. Results The experience of treatment of 5 patients with COVID-19 with arterial and venous thrombosis was analyzed. All patients showed characteristic changes in the coagulogram. The patient who, upon admission, had a negative test for COVID-19, and characteristic changes in the coagulogram appeared on the day of recurrent thrombosis, was of greatest interest. All patients received standard treatment and were discharged with improvement after testing negative for COVID-19.Conclusion. Generalization of the clinical course of patients with COVID-19 and thrombosis of various vascular regions allowed us to develop treatment tactics for these groups of patients.
