Pulmonary Thromboembolism in COVID-19: Venous Thromboembolism or Arterial Thrombosis?
Enrico Cavagna, Francesco Muratore, Fabio Ferrari
Abstract
PURPOSE: To investigate CT pulmonary angiography findings of pulmonary thromboembolism (PTE) in coronavirus disease 2019 (COVID-19) and its association with clinical and radiologic conditions. MATERIALS AND METHODS: test. RESULTS: = .042). CONCLUSION: PTE in COVID-19 involves mainly the segmental and subsegmental arteries of segments affected by consolidations in patients with more severe lung disease. The authors hypothesize that the development of PTE in COVID-19 might be a pulmonary artery thrombosis because of severe lung inflammation and hypercoagulability rather than thromboembolism.© RSNA, 2020.
