AIM: The authors set out to evaluate the correlations between three of the main morphological aortic parameters (aortic diameter, intima, and media thickness) and the cause of death.
MATERIALS AND METHODS: Study group included 28 people died of a cardiovascular (CV) disease and 62 people died of a noncardiovascular (NCV) disease. Four aortic cross-sections (base, cross, thoracic, abdominal) were collected during autopsy from the selected cases, fixed in 10% buffered formalin and photographed together with a calibrating ruler. Then, they were processed using the classical histopathological (HP) technique (formalin fixation and paraffin embedding), stained with Hematoxylin-Eosin (HE) and Orcein, and the obtained histological slides were transformed into virtual slides. Aortic diameters were determined on calibrated photos using a custom-made software, developed in MATLAB (MathWorks, USA). Intima and media thicknesses were determined on virtual slides using a dedicated image analysis software.
RESULTS AND DISCUSSIONS: The most frequent CV causes of death were the ischemic heart diseases and the most frequent NCV causes of death were the inflammatory diseases. Aortic diameter decreased from the aortic origin till the aortic end, with larger values in women than in men and in CV diseases than in NCV diseases. The difference in the remodeling of the aortic diameter between the two groups is smaller towards the abdominal region. Intima thickness increased from the aortic origin till the aortic end and was larger especially in women died of CV diseases, whereas in men there were some shifts at the extremities of the aorta. The difference in the remodeling of the intimal thickness between the two groups is extremely variable. Media was thicker in almost all of its segments in CV group than in NCV. It was a divergent evolution of the correlation degree trends in the two groups.
CONCLUSIONS: The three morphological parameters of the aorta (diameter, intima, and media thicknesses) are more or less influenced by the pathological status that caused patient's death by the patient's sex and by the topographic region where the measurement was made.
