CORRELATION BETWEEN THE CT SEVERITY SCORE OF COVID-19 PNEUMONIA AND PULMONARY EMBOLISM

Abstract

Objectives: To correlate the lung parenchymal involvement in COVID-19 patients and the incidence of thrombosis, determine type of thrombosis and the level of pulmonary system involved. Computed Tomography Pulmonary Angiography (CTPA) was Methods: performed in 50 COVID19 positive patients. The patients were stratied into positive and negative for thrombosis. The type of thrombosis, level of the pulmonary system involvement and other factors like d-dimer levels and presence of co-morbidities were taken into account in patients who had thrombosis. Results: There is an increased incidence of thrombosis among the patients with higher severity of COVID-19, increased d-dimer levels and presence of comorbidities. Amongst the arterial system, the segmental branches were most commonly involved and partial thrombosis was the most commonly encountered type of thrombosis. Increased severity of COVID-19 pneumonia along with other fac Conclusion: tors like elevated d-dimer levels and presence of comorbidities lead to an increased incidence of thrombosis in patients with COVID-19 pneumonia
