Sex-Specific Parameters of Ascending Aorta, Descending Aorta and Pulmonary Trunk by Computed Tomographic Angiography with Impact of Age, Hypertension, Smoking and Diabetes/Parametros Especificos de la Parte Ascendente de la Aorta, Parte Descendente de la Aorta y Tronco Pulmonar Analizados Mediante Angiografia por Tomografia Computadorizada Relacionados con el Sexo, Impacto de la Edad, Hipertension, Tabaquismo y Diabetes

This study aims at establishing whether transverse diameter (TD) and cross sectional-area (CSA) of the ascending aorta (AA), descending aorta (DA) and pulmonary trunk (PT) measured by computerized tomographic angiography (CTA) altered by sex, age, hypertension, smoking and diabetes. CTA examinations of the TD and CSA of the AA, DA and PT of 100 patients aged 49.5 [+ or -] 16.9 years (range 16-78 years) selected between January 2009 to May 2011 from those referred to Radiology Department, Jordan University Hospital, Faculty of Medicine, University of Jordan, Amman, Jordan for advanced evaluation. Measurements were made in the axial plane at the upper border of the six thoracic vertebrae. Patients were divided into three age groups. Significance of differences in parameters between age groups was calculated. Assessment ratios were considered. It was found that parameters of the three arteries were significantly larger in men than in women (P= < 0.05) and increased with age. Hypertension increased diameters of AA and DA in both genders (P= 0.001) and of PT in men (P= 0.01). Smoking significantly decreased parameters of PT in men (P= 0.01). Diabetes increased parameters of the three arteries in both genders, significantly increased parameters of PT in men (P=
