dc.description.abstractPurpose To investigate whether the increased obstruction of the pulmonary arteries was associated with reduced pulmonary vein areas in acute pulmonary embolism (APE). Method We retrospectively analyzed a consecutive series of computed tomography pulmonary angiography studies of 107 patients with APE and 101 controls without APE between November 2010 and January 2019. The control and patient groups were compared with each other for differences between the mean cross-sectional areas of pulmonary veins. Further analysis was conducted by dividing the patient group into high-risk patients (>= 20%) and low-risk patients (< 20%) according to the pulmonary arterial obstruction index. The mean cross-sectional area of the pulmonary veins in these two groups was compared. Results The mean cross-sectional areas of the 4 pulmonary veins at the ostium level (CSAPV) were significantly lower for the patient group (mean: 102.6 mm(2)) compared with the control group (111.8 mm(2)) (p < 0.001). CSAPV cutoff value for determining the diagnosis of APE that maximized the accuracy was 109.12 mm(2) (AUC = 0.721; 95% CI 0.649-0.794); its sensitivity and specificity were 78.2% and 69.2%, respectively. CSAPV cutoff value for differentiating high-risk APE that maximized the accuracy was 102.6 mm(2) (AUC = 0.634; 95% CI 0.525-0.743); its sensitivity and specificity were 61.9% and 53.8%, respectively. Conclusions There is a negative correlation between the CSAPV and thrombotic material burden in the pulmonary arteries of patients with APE. Hence, the CSAPV can be used as a diagnostic tool in the evaluation of the presence and severity of pulmonary embolism.en_US
