BackgroundOn 31 December 2019, the World Health Organization (WHO) was informed of a cluster of cases of pneumonia MESHD pneumonia HP of unknown cause detected in Wuhan City, Hubei Province, China. The pneumonia MESHD pneumonia HP was caused by a virus called SARS-Cov-2, which was later named COVID-19. In this report, we present a patient with COVID-19 who developed deep vein thrombosis MESHD.Case presentationA 57-year-old woman presented to the clinic's infectious department with no underlying illness due to pain MESHD pain HP, redness, and leg swelling. According to a patient report, she had a mild dry cough MESHD cough HP for the past 3 days and had no other symptoms. The patient had no history of prone thrombosis MESHD conditions. Initially, CT angiography was performed to rule out pulmonary thromboembolism MESHD thromboembolism HP, which showed no evidence of thrombosis MESHD. Dilatation HP and thrombosis MESHD were seen in the examinations of the paired veins of the leg, popliteal, superficial and left femoral joints, and no evidence of vascular flow suggesting acute DVT. Because of fever MESHD fever HP and lymphopenia MESHD lymphopenia HP, nasal swabs were used for sampling and SARS-CoV-2 nucleic acid was detected by RT-PCR. Chest X-ray also revealed bilateral patchy ground-glass opacity. Other tests including ANA, Anti-dsDNA, RF test and ACA test was normal. Heparin at a dose of 80 units/kg IV bolus, chloroquine 400 mg single dose and lopinavir/ritonavir (Kaletra) 400 mg twice daily were prescribed to treat illness and relieve symptoms. On illness day 3, fever MESHD fever HP stopped and nasal swab sample turned undetectable for SARS-CoV-2 by RT-PCR as well as swelling and tenderness on her leg had been disappeared gradually. She is under regular follow-up with no new symptoms to date.Conclusion The mechanism of DVT formation due to COVID-19 is unknown despite thrombocytopenia MESHD thrombocytopenia HP, and has not been investigated but it resolved as COVID-19 symptoms, tenderness, and leg pain MESHD pain HP improved. Although COVID-19 presented with Deep Vein Thrombosis MESHD is a rare condition, in middle- aged TRANS people with sudden onset of manifestations, we should recognize it from other diseases MESHD as an important and treatable differential diagnosis. Rapid diagnostic assays, efficient treatment, and prudent use of CT-scan are important to control future COVID-19 spread.
