Assessment of Pulmonary Embolism Severity and Scoring Using Multi Slice CT in Correlation with Clinical Presentation and Echocardiography
Journal Title: The Egyptian Journal of Hospital Medicine - Year 2018, Vol 71, Issue 3
Abstract
<span>Aim of the work</span><span>: The aim of this study is to evaluate the correlation between pulmonary embolism </span> <span>severity and scoring obtained using multi slice CT (MSCT) and the clinical presentations and echocardiography in patients with pulmonary embolism (PE). </span><span>Patients and method</span><span>: this study was carried out in the Radiology Department of Ain Shams University Hospitals. 21 patients with PE. The CT obstruction index (OI) using Qanadli score and the RV/LV diameter Right ventricle dysfunction ratio (RVD-ratio) using the four-chamber view of the heart were calculated for all patients. The cut-off for the OI to detect RVD was constructed using ROC curve. They were 13 (61.9%) females and 8 (38.1%) males. Their age was ranged from 22 -83 years old. R</span><span>esults: </span><span>Dyspnea and RVD (RVD-ratio >1) were significantly more common in patients with severe pulmonary embolism. Regarding the echo findings with PE high Right ventricular systolic pressure (RVSP) was the commonest echo finding among our studied patients. The cutoff point of obstruction index (OI) >15 (Qanadli score >37.5 %) has the highest prediction value of right ventricular dysfunction, indicating that most of the patients with a score of more than 37.5% had RVD that was agreed with echo findings. </span>
