Deep vein thrombosis in COVID-19 patients in general wards: prevalence and association with clinical and laboratory variables

Abstract: Background Preliminary reports suggest a hypercoagulable state in COVID-19. Deep vein thrombosis (DVT) is perceived as a frequent finding in hospitalized COVID-19 patients, but data describing the prevalence of DVT are lacking. Objectives We aimed to report the prevalence of DVT in COVID-19 patients in general wards, blinded to symptoms/signs of disease, using lower extremities duplex ultrasound (LEDUS) in random patients. We tested the association of DVT with clinical, laboratory and inflammatory markers and … Show more

“…Lower extremity thrombosis classification has been suggested by the DVT guidelines and is widely used in clinical practice, and this classification stratifies the DVT patients into four classes [9]. Regarding the class, the majority of the DVT patients were diagnosed as Class I, which was consistent with other published papers [9], [15], [24]. The greatest number of detected DVT cases was in calf veins, but because of later complications such as the post-thrombotic syndrome and the mortality of 27% in these patients, early diagnosis and treatment is obligatory [9].…”

“…Several studies demonstrated a significant increase in D-dimer and fibrinogen levels [23] as well as CRP value [24], which reflected the hypercoagulability state. On the other hand, Motaganahalli et al proved that the value of CRP is not associated with DVT [25].…”

“…Each biomarker considered in the inflammation-based risk scoring system was independently assessed for thrombosis in patients with COVID-19. Indeed, C-reactive protein was in-dependently associated with the presence of a deep-vein thrombosis demonstrated by duplex ultrasound as well as a pulmonary embolism demonstrated by computed tomography pulmonary angiography [34,35]. Moreover, C-reactive protein levels may predict the occurrence of venous thromboembolism in critically ill COVID-19 patients admitted to the ICU with an AUC of 0.75; for comparison, the AUC of the D-dimer in this study was only 0.64 [36].…”

“…Ultrasound (US) is an imaging tool is cheap, noninvasive, non-irradiating and, thus, repeatable, suitable for patient disease monitoring [22][23][24][25]. Contrast-Enhanced Ultrasound (CEUS) imaging is an improved ultrasound-based technology, assuming the injection into the blood of a specific contrast agent, consisting of gas filled microbubbles [22].…”
