ABSTRACT
Background:
In pulmonary embolism, the computed tomography (CT) images can be used as a prognostic index measuring the embolic load, according to the location and size of thrombus and the right/left ventricular diameter ratio. Aim To assess the predictive value of embolic load and right/left ventricular diameter ratio for early and íate mortality in acute pulmonary embolism (PTE). Material andmethods:
The pulmonary CT of 418 patients with suspected PTE were reviewed. Embolic load was assessed by three independent evaluators and the right/left ventricular diameter ratio was measured in those exams that were positive for PTE. A logistic regression analysis was done between these parameters and mortality. ReproducibUity was calculated using Bland andAltman analysis.Results:
There was a high concordance between raters to calculate embolic load (r =0,95, p <0,001). Only the right/left ventricular diameter ratio and the presence were predictive of global mortality. The predictive value for embolic load was below the significance level No parameter was predictive of early mortality.Conclusions:
The concordance between raters for the assessment of embolic load was high in this study. However no imaging parameter had a predictive value for early mortality. The right/left ventricular diameter ratio had a predictive value for global mortality at three months.
