The Prevalence of Deep Vein Thrombosis and Associated Risk Factors Among Patients with COVID-19 in the North of Iran

Abstract

Aim: We aimed to investigate the associated risk factors of deep vein thrombosis (DVT) among COVID-19 patients. Materials & methods: In this cross-sectional study the demographical data and clinical characteristics of 382 COVID-19 patients were collected and analyzed. Results: The DVT was observed in 53 patients (14.1%). The rate of death was significantly associated with the incidence of DVT, 48.1 versus 32.2% in non-DVT cases; p = 0.034). Also, BMI (p = 0.0001), renal failure (p = 0.001), lower-limb edema (p = 0.0001) and intubation (p = 0.004) were associated with the risk of DVT. Conclusion: COVID-19 patients with a higher BMI, renal failure, lower-limb edema and need for intubation were at a higher risk of DVT.
