Abstract

The aim of this study was to determine whether pulmonary embolus volume (PEV) obtained with multi-detector row computed tomography is related to clinical status and outcomes. Subjects comprised 48 patients with acute pulmonary embolism (PTE). PEV was measured by tracing the contours manually and compared between sets of two groups divided by clinical status. Correlations of PEV to blood gases and D-dimer levels were investigated. PEV was tested as a predictor of clinical probability of acute PTE using Wells' criteria and as a predictor of survival after PTE by logistic regression analysis. The PEV was greater in groups with respiratory symptoms (P < 0.001), PTE as pretest clinical diagnosis (P = 0.027), and heart rate >100 beats/min (P < 0.001). It was smaller in subjects with concurrent malignancy (P = 0.02). It was correlated with PaCO(2) (P = 0.04, rho = -0.37) and the D-dimer level (P = 0.002, rho = 0.46); it was not a predictor of clinical probability of acute PTE or survival after PTE. The survival rate did not differ between groups with PEV > 10 ml (8/9) or <or=10 ml (32/36). The PEV in acute PTE may relate to the presence of respiratory symptoms, hypocapnia, and tachycardia. The PEV was smaller in patients with malignan...Continue Reading
