Abstract
BackgroundPatients with pulmonary embolism have high mortality and morbidity rate due to right heart failure and circulatory collapse leading to sudden death. Multi-detector computed tomography MDCT can efficiently evaluate the cardiovascular factors related to pulmonary embolism. ObjectivesTo evaluate the diagnostic accuracy of multi-detector computed tomography (MDCT) in differentiation of between sever and non-severe pulmonary embolism groups depending on the associated cardiovascular parameters and create a simple reporting system. Patients & methodsProspective study contained 145 patients diagnosed clinically pulmonary embolism. All patients were examined by combined electrocardiographically gated computed tomography pulmonary angiography-computed tomography venography (ECG-CTPA-CTV) using certain imaging criteria in a systematic manner. ResultsOur study revealed 95 and 55 non-severe and severe pulmonary embolism groups respectively. Many cardiovascular parameters related to pulmonary embolism shows significant p value and can differentiate between sever and non-severe pulmonary embolism patients include pulmonary artery diameter, intraventricular septum flattening, bowing, superior vena cava and Azygos vein diameters, right and left ventricular diameters. ConclusionMulti-detector computed tomography (MDCT) can be valuable to assess the severity of pulmonary embolism using the related cardiovascular parameters and leading the management strategy aim for best outcome.
