| Abstract | ||||
| Background: Pulmonary embolism (PE) is defined as occlusion in the pulmonary arterial tree, preventing blood flow distal to the occlusion. PE is most frequently caused by thrombosis in a systemic blood vessel, usually in a deep vein of the lower limb(1). Results: Regarding clinical data between PE positive and negative cases, PE-positive cases have significantly higher rates of hemoptysis (43.3% vs. 22.9%, p=0.05), chest pain (93.3% vs. 68.6%, p=0.01), acute dyspnea onset (70% vs. 42.9%, p=0.02), lower limb edema (76.7% vs. 34.3%, p=0.001) Regarding Geneva and modified Wells scores between PE-positive and PE-negative cases, their significance in risk stratification (p<0.001 for both). PE-positive patients, 36.7% had a high Geneva score, while 50% were intermediate risk,. Similarly, 30% of PE-positive cases had a high modified Wells score,while 26.7% were moderate risk. However, 43.3%of PE-positive cases were classified as low risk by the Wells score,. Methods: This is a cross section observation study that was carried out on sixty five patients presented to Minia University Hospitals for doing CTPA during the period from January 2024 to January 2025. The aim of work is to assess validity for diagnosis of PE using some of commonly used diagnostic predictive methods for diagnosis of pulmonary emolism. Conclusion:This study highlighted CTPA is the gold standard for diagnosing PE, and in this study, . The modified Wells and Geneva scores are useful tools for risk stratification, with the modified Wells score indicating a higher prevalence of low-risk patients, though it had limitations in identifying high-risk PE cases. | ||||
