Abstract

During the COVID-19 pandemic, investigations have reported a high incidence of venous thromboembolic (VTE) events in hospitalized patients with coronavirus disease 2019 (COVID-19) often despite thromboprophylaxis. However, the risk of Deep venous thromboembolism(DVT) extends from the time of admission and over the first 90 days post hospital discharge in COVID-19 patients to this regard, the actual post-discharge cumulative incidence of DVT events in patients hospitalized for COVID-19 pneumonia has not been clearly determined, limiting the formulation of clinical recommendations regarding the need for optimal duration of extended thromboprophylaxis strategies. Methods: The study is a clinical prospective observational study all the eligible patients attending medicine department outpatient/ inpatient who matched the inclusion criteria. A detailed history thorough physical examinations were performed. Data were collected from the patients who admitted in COVID 19 block. Telephone contact numbers and detailed addresses were collected for follow-up. Results: In our study prevalence of DVT in post COVID 19 patients is 7%, majority of subjects with DVT were in the age group 61 to 70 years (42.9%), males were in majority (85.7%).There is significant association with risk factor like systemic Hypertension, Diabetes mellitus, chronic kidney disease, chronic obstructive pulmonary disease, obesity, severity and length of hospital stay.Lab parameters like elevated D-dimer,CRP and alkaline phosphatase have ability to predict the DVT. There is significant association with thromboprophylaxis at discharge and incidence of DVT. Conclusion: The findings of this study suggest that covid-19 is a risk factor for deep veinthrombosis. These results could impact recommendations on diagnostic and prophylactic strategies against venous thromboembolism after covid-19
