Frequency of Pulmonary Embolism (PE) in Suspected Cases using Computed Tomography Pulmonary Angiography (CTPA).

Abstract

Objective: To evaluate the frequency of pulmonary embolism in suspected patients through Computed tomography pulmonary angiography (CTPA). Study Design: Descriptive, Cross-sectional study. Setting: Department of Radiology, Chaudhary Pervaiz Elahi Institute of Cardiology, Multan. Period: 25 October 2019 to 25 October 2020. Material & Methods: The study contained 152 patients who were referred to the Department of radiology for diagnosis of PE through computed tomography pulmonary angiography (CTPA). Demographic characteristics of all the included subjects were also noted. Computed tomography pulmonary angiography was done in all subjects and results were analyzed for absence or presence of PE by expert radiologists. Results: The mean age of included subjects was 49.36±10.34 years. The number of female patients was 95 while the number of the male was 57. The mean duration of the symptoms was 3.86 ±1.7days. 126 patients (82.89%) did not have pulmonary embolism while 26 (17.11%) were diagnosed with PE. Duration of symptoms, gender, and age stratification was done. The Association of these factors with pulmonary embolism was not found to be significant. Conclusion: The study showed that the frequency of PE diagnosed in suspected patients through Computed tomography pulmonary angiography was17.11%.
