Quantitative evaluation of computed tomography findings in patients with pulmonary embolism: the link between D-Dimer level and thrombus volume

Abstract: OBJECTIVE:To investigate the correlation of D-dimer levels and computed tomography properties of pulmonary embolism.METHODS: A total of 58 treated patients with diagnosis of properties of pulmonary embolism were retrospectively studied. All patients underwent a D-dimer blood test. In computed tomography images, septal angle, interventricular septal thickness, and the diameters of all cardiac chambers and pulmonary arteries were measured. The thrombus volume (load) and density at all pulmonary arteries (main, r… Show more

“…Increasing TEV and Qanadli score can both indicate a larger clot burden in the pulmonary arterial circulation, which can lead to pressure overload and RV dilatation. Recently, a small study with fifty-eight patients with acute pulmonary embolism showed that quantitative volumetric measures of TEV was positive correlation with RV/LV ratio 19 . In our study, TEV and the Qanadli score were well correlated, especially in the case of main pulmonary arterial involvement.…”

“…Currently, although there are a few studies on MPATE risk factors abroad, the claims and results are inconsistent. Zuin M et al believed that high diastolic blood pressure was a risk factor for MPATE 3 , while Sasani H et al suggested that plasma D-dimer (D-D) level was positively correlated with the ratio of right ventricular/left ventricular diameter in MPATE patients 4 , so patients with high D-D level were more likely to develop MPATE. Because the symptoms of MPATE are not typical and are often confused with other cardiopulmonary diseases, the probability of misdiagnosis is high in early recognition, leading to a delay of the optimal treatment time for MPATE.…”
