Objectives: To study pulmonary embolism during COVID-19 pneumonia.
Patients and Methods: This was a one-year retrospective and descriptive study of all
patients from three imaging sites with SARS-CoV2 infection.
Results: Two hundred and thirty-nine patients were included. The prevalence of
pulmonary embolism was 18.4%. The average age was 55 years old. The sex ratio was
1.65. Dyspnea (58.6%), cough (56.1%), and chest pain (40.2%) were the most common
reasons for consultation. In 151 patients (63.2%), chest computed tomography (CT)
angiography was performed without checking level of D-dimer. The level of D-dimers
was elevated in 47.8%. Grade 5 of CO-RADS accounted for 62.3%. In 70.5% of cases,
the pulmonary embolism was bilateral with subsegmental involvement in 47.7%.
Condensation in ‘ground glass’ with ‘crazy paving’ were the predominant typical
parenchymal lesions with a frequency of 93.7% and 59.4%. In univariate analysis,
D-dimers were significantly associated with the occurrence of pulmonary embolism (p
