Post-covid Syndrome in the Form of Venous and Arterial Thrombosis Complicated COVID-19

Abstract

Post-covid syndrome in the form of thrombosis is a common and dangerous complication of COVID-19. To identify the localization, frequency, timing of thrombosis in patients who have undergone COVID-19, the frequency of surgical treatment methods used. A retrospective observational study of 239 case histories of patients (138 women and 101 men) who had COVID-19 in the Department of Vascular Surgery of the National Hospital of the Ministry of Health of the Kyrgyz Republic within the period from August to December 2020. A 42-year-old patient who underwent COVID-19 in March 2020, which gave a post-covid complication in the form of a chronic aneurysm of the infrarenal abdominal aorta five months later. Venous thrombosis as a post-covid syndrome is 74% more common than arterial thrombosis. The incidence of thrombotic post-covid syndrome in women compared to men is 15.4% higher. This trend is most pronounced in the disabled aged 61 and over. Venous thrombosis was most often localized in the veins of the lower extremities, and open surgical interventions were most often performed. People with concomitant diseases, in particular, with diseases of the cardiovascular system, are more susceptible to post-covid complications in the form of thrombosis and thromboembolism. Out of 239 people, 138 people (58%) had concomitant diseases, 101 people (42%) did not have them. Basically, open surgical interventions were performed. In 50% of cases with arterial thrombosis, thromboembolectomy was performed, with venous thrombi, the ligation of the great saphenous vein according to Troyanov accounted for 78% of operations. In the case of an individual clinical patient, laparotomy, nephrectomy on the right, elimination of an aortic aneurysm, aorto-femoral bifurcation prosthetics with an ECOFLONprosthesis were performed. Post-covid syndrome after COVID-19 is mainly localized in the veins of the lower extremities and is much more common among the female population with concomitant diseases. Open surgical operations can effectively eliminate the post-covid syndrome.
