Abstract

To evaluate the role of CT pulmonary angiography (CTPA) in the assessment of pulmonary embolism (PE) severity and the related CT cardiac changes, reflecting the clinical status of the patients and predicting the outcome. A prospective study of 184 patients presented with suspicious acute PE. All patients underwent CTPA followed by ECHO. Pulmonary artery obstructive index (PAOI) using Qanadli Score was calculated and cardiac changes recorded. The patients’ outcome was followed up for 30 days. Only 150 patients completed the study; 26.7% needed ICU admission while 13.3% died during follow-up. There was a significant relationship between the PAOI and the risk classification, right ventricular dysfunction (RVD) diagnosed by ECHO and the patients’ short outcome. We found PAOI cut off value 45% for mortality and 35% for ICU admission and 27.5% for RVD with 60, 75 and 90% sensitivity and 80, 73.3 and 68.6% specificity respectively. CT RV/LV ratio was the most sensitive parameter to predict RV dysfunction followed by pulmonary artery diameter. CTPA is not only used for diagnosis but also to assess the severity of PE, the effect on the right ventricular function and subsequently the need for ICU admission and prediction of the outcome.
