The balance between pro-coagulant factors and natural coagulation inhibitors in critically ill patients with Covid-19 is fundamental to the prevention and treatment of complications. The aim of the present study was to investigate the pulmonary injury patterns in Covid-19 having higher mortality in the presence of deep vein thrombosis in comparison to patients without venous thrombosis and determine the Gamma variant.Methods: A retrospective study was conducted involving the evaluation of 200 medical records of patients with Covid-19 and a clinical suspicion of deep vein thrombosis (DVT) at the intensive care unit of a public hospital. The sample was divided into two groups of patients were formed – those positive and those negative for DVT. Statistical analysis involved the use of Fisher’s exact test, the paired t-test and chi-square test.Results: Patients with DVT had more severe lung injuries (greater than 70%) compared to those without DVT (p = 0.003). Lesions affecting 50% to 70% of the lung area occurred in little more half of the group with DVT and just under half in the group without DVT (p = 0.5). Pulmonary lesions affecting less than 50% of the lung occurred more in patients without DVT (p = 0.0001). The Gamma variant increased prevalence of the both DVT and mortality (p=0.0001).Conclusion: Deep vein thrombosis is an aggravating factor of mortality in patients with SARS-CoV-2, and the Gamma variant is an aggravating factor of both thrombotic events and mortality.Keywords: Covid-19, deep vein thrombosis, pulmonary thrombosis, mortality
