He had raised temperature, tachycardia, tachypnoea, reduced oxygen saturation and swollen tender left leg on examination. The frontal chest radiograph showed bilateral ground-glass opacities; he tested positive for COVID-19 with elevated D-dimer. The colour Doppler examination of the left leg revealed acute deep vein thrombosis (DVT) of the common femoral and the popliteal veins. The chest CT showed bilateral diffuse ground-glass opacities predominantly involving peripheral zones and the lower lobes. The CTPA revealed left pulmonary thromboembolism (PTE), treated with low-molecular-weight heparin. COVID-19 predominantly affects the respiratory system. DVT and PTE are common in COVID-19 but lethal. They should be diagnosed early by clinical and radiological examinations and treated promptly with anticoagulants.<\/jats:p>","DOI":"10.1136\/bcr-2020-240932","type":"journal-article","created":{"date-parts":[[2021,1,15]],"date-time":"2021-01-15T11:41:16Z","timestamp":1610710876000},"page":"e240932","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Deep vein thrombosis with pulmonary thromboembolism in a case of severe COVID-19 pneumonia"],"prefix":"10.1136","volume":"14","author":[{"given":"Sujata","family":"Devi","sequence":"first","affiliation":[{"name":"General Medicine, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sudipta","family":"Mohakud","sequence":"additional","affiliation":[{"name":"Radiodiagnosis, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nilanjan","family":"Kar","sequence":"additional","affiliation":[{"name":"General Medicine, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Divya","family":"Muthuvel","sequence":"additional","affiliation":[{"name":"Radiodiagnosis, All India Institute of Medical Sciences Bhubaneswar, Bhubaneswar, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,1,15]]},"reference":[{"key":"2025082709502672000_14.1.e240932.1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa2001017"},{"key":"2025082709502672000_14.1.e240932.2","unstructured":"World Health Organization .
