Aortic Aneurysm with and without Dissection and Concomitant Atherosclerosis—Differences in a Retrospective Study

Abstract

Background: Thoracic aortic aneurysm is a latent disease with a high risk of death. Today, as data are accumulating, an estimation of the differences in thoracic aneurysm in men and women of different age groups is required. The present study evaluated the type of atherosclerotic aortic lesions in males and females at different ages regarding the presence or absence of aortic dissection. Methods: A retrospective analysis of clinical and morphological data of 43 patients with thoracic aortic aneurysm was carried out. Patients were divided into groups based on the presence or absence of thoracic aneurysm dissection. Results: Our results of a comparative analysis of the age of study participants showed that patients with aneurysm dissection were younger than patients without dissection. In the subgroup of patients with aortic dissection, the mean age was 50.6 years old, and in patients without aortic dissection, the mean age was 55.0 years old. When conducting a frequency analysis using Fisher’s exact test, it was found that in men and women aneurysm dissection was not associated with atherosclerotic lesions of the aorta. Conclusions: In women and men, aneurysm dissection was not associated with stage of atherosclerotic lesions of the aorta regardless of age; no statistically significant differences were found between the groups with and without aneurysm dissection (p > 0.05). Dissection of the thoracic aneurysm developed in the absence of severe atherosclerosis of the thoracic aorta. Only 18.6% men and women possessed atherosclerotic plaques of types IV and V.
