Evaluation of Inferior Vena Cava/Abdominal Aorta Diameter Index in Pulmonary Embolism
Journal Title: Eurasian Journal of Emergency Medicine - Year 2020, Vol 19, Issue 2
Abstract
Aim: Among cardiovascular diseases, pulmonary embolism (PE) is a serious emergency with high mortality. Right ventricular dysfunction due to an excessive increase in pulmonary artery pressure is considered a major cause of death in vigorous PE. We aimed to assess the predictive value of computed tomographic pulmonary angiography (CTPA)-based morphometric measurements of right heart function in the diagnosis of PE. Materials and Methods: This is a retrospective, case-controlled study. A total of 198 cases were included in the study during the study phase. CTPA results of 102 patients with PE were recorded, and the patients were grouped according to clot localisation. The diameters of the inferior vena cava (IVCA), aorta, pulmonary artery and right and left ventricles were assessed. Results: IVCA area/aortic area significantly predicted embolism in the main pulmonary artery [area under the curve (AUC)=0.957, p<0.001]. The optimal cut-off value was 1.22 with 88% sensitivity and 90% specificity. IVCA diameter/aortic diameter significantly predicted embolism in the main pulmonary artery (AUC=0.955, p<0.001). The optimal cut-off value was 1.1 with 89% sensitivity and 88% specificity. Conclusion: Our study illustrated a remarkable association between the existence and dispersion of PE and morphometric changes in IVCA and aortic ratio parameters measured using CTPA.

The Interaction Level of Emergency Department Patients with Their Family Physicians and Their Expectations from Primary Health Care: A Survey Study
Aim: One of the main reasons of emergency department (ED) crowding is that non-urgent patients often use EDs instead of primary health care. The aim of this study was to determine the interaction level of ED patients wit...
