The Value of CT Angiographic Score in Predicting Clinical Outcome of Acute Pulmonary Embolism

Abstract

The aim of this study was to investigate the association between acute pulmonary embolism and mortality and the severity of pulmonary artery occlusion based on scoring system in CT angiography in patients with pulmonary embolism. Methods and materials: In this cross-sectional study, patients with pulmonary thromboembolism were included in the study. The type of disease, the outcomes of the disease, including MACPE and death, were recorded in each 6-month follow up. Pulmonary CT angiography of 174 patients with acute pulmonary embolism and no previous comorbidity were reviewed at this prospective study. In addition, the pulmonary artery obstruction score was determined according to Qanadli. Finally, the relationship between these findings was evaluated together. Data were analyzed by SPSS 22 software.

Results: Among the 90 men and 84 women with a mean age of 60.4 ± 17.2 years, we found the value of the spiral CT angiography score to predict the outcomes of acute pulmonary embolism, while CT-Score was not an appropriate indicator for predicting the deaths of patients with embolism Pulmonary embolism (P-value = .83), and massive pulmonary embolism (P-value = .25), although it could predict the need for MACPE (P-value = .001) care. Also, by performing linear regression, it was observed that the CT-Score could predict the number of hospitalizations days (P- value = .000)
