Chapter 1 10 patients with coronavirus disease 19 (COVID-19) pneumonia who are suspected of concomitant acute PE. COVID-19 has been associated with high rates of VTE 11 , particularly PE. Based on the results of autopsy studies it was suggested that thrombosis may often be the result of an in-situ immunothrombosis rather than conventional thromboembolism. 12 To further evaluate whether COVID-19 associated PE differs from conventional PE, clinical and CT characteristics of PE in patients with COVID-19 pneumonia were compared to those in patients without COVID-19 pneumonia ( Chapter 12 ).
