Abstract

Background: COVID-19-positive patients may present with hypercoagulability and an increased liability to develop deep vein thrombosis (DVT). The preferred imaging technique for detecting the presence of deep vein thrombosis in the lower limb is complete duplex ultrasonography.
Objectives: To estimate the incidence of lower limb deep venous thrombosis (DVT) as a complication of COVID-19 infection among post COVID-19 patients by venous Doppler ultrasound.
Patients and methods: This was a prospective study where fifty patients were followed up for three months after COVID-19 recovery. Lower limb venous Doppler ultrasound was done at Diagnostic and interventional radiology Department after the patients were referred from Vascular Surgery Department.
Results: This prospective study was carried out on 50 patients after COVID-19 recovery. The overall DVT incidence among COVID-19 patients was 6%. After 1 month 96% of cases had no DVT but 4% had DVT (2.0% had right extensive DVT and 2% left femorpopliteal DVT), at 3 month follow up, 94% of cases had no DVT but 6% had DVT (2.0% had right extensive DVT and 4% left femorpopliteal DVT).
Conclusion: The overall DVT incidence among post COVID-19 patients in this study was 6%. Old age and increased D-dimer were significantly associated with COVID-19 severity. Cardiac disorders and obesity were significantly associated with incidence of DVT among COVID-19 patients.
