Abstract

Background: Among the multiple complex pathophysiological mechanisms underlying Covid-19 pneumonia, immunothrombosis has been shown to play a key role.

Objective: The aim of the present study was to assess the monthly prevalence of deep venous thrombosis in a university hospital that admitted 5159 patients with Covid-19 in the medical ward and intensive care unit (ICU) and investigate whether there has been an increase in the prevalence of deep vein thrombosis and dead recently.

Method: A clinical trial was conducted evaluating 5159 patients admitted to the university hospital, Hospital de Base in São Jose do Rio Preto-Brazil, with a positive test for Covid-19, the prevalence of monthly deep venous thrombosis and the increase in thrombotic and events and mortality in March 2020 to April 2021 compared to the previous January and February with March-April of 2021. The evaluated by Fisher's exact test.

Results: The prevalence of deep vein thrombosis varied between the months of 0.26% to 7%, with an average of 2.5%. The months of March and April 2021 had a significant increase in venous thrombosis and mortality in relation to the months of January and February 2021.

Conclusion: The prevalence of deep venous thrombosis was variable during the months evaluated, since the beginning of Covid-19, but there was a significant increase in these last two months.

Keywords: Covid-19; Prevalence; deep vein; mortality; thrombosis.
