| Popis | Aim. To evaluate the association between computed tomography parameters and clinical signs in patients with acute pulmonary embolism. Methods. 109 patients retrospectivelly selected from hospital database with acute pulmonary embolism verified by CT pulmonary angiography. The following parameters were assessed: pulmonary artery diameter to aorta diameter ratio (PA/Ao), normalized pulmonary artery diameter (nPA), right ventricular to left ventricular diameter ratio from CT (RV CT/LV CT), normalized end-diastolic right ventricular diameter (nRVD echo) and right to left ventricular end diastolic diameter ratio (RV echo/LV echo) from echocardiography. Results. Multivariate regression analysis showed a significant association between PA/Ao and thrombolysed (0.99) to non-thrombolysed (0.90) patients, OR=1.56 P=0.012, and also RV CT/LV CT and thrombolysed 1.5 to non-thrombolysed (0.94) patients OR=1.24 P=0.002. The significant difference was also found in intensive care unit hospitalization necessity (ICU-Y/N) and RV CT/LV CT ratio (ICU-Y 1.42, ICU-N 0.91) OR=1.26 P=0.003, and RV echo/LV echo (ICU-Y 0.82, ICU-N 0.65) OR=1.83 P=0.033. Conclusion. From the CT pulmonary angiography parameters, the RV CT/LV CT showed a significant association with both thrombolysis administration and ICU hospitalization. The PA/Ao had relation only to thrombolytic therapy as well as RV echo/LV echo only to ICU hospitalization. |
