An aneurysm is a irreversible and permanent localized dilation of an artery. A false aneurysm or pseudoaneurysm is a dilatation resulting from an artery injury, in which the outer wall is made of fibers without a vascular structure. Morphologically, aneurysms can be fusiform, when the dilatation affects the entire artery, or saccular, when only part of the circumference of the artery is affected. Aneurysms that occur in the abdominal aorta distal to the renal arteries (infrarenal aorta is the most common place for development of an aortic aneurysm) are called abdominal aortic aneurysms (AAA). Degenerative process in aortic wall is the most common cause of abdominal aortic aneurysm, therefore more than 90% of AAA are degenerative. Most common risk factors for AAA are old age, smoking and male gender, white race, hypertension, dyslipidemia, COPD, coronary heart disease, peripheral artery disease, and a previous positive family history. Smoking is one of the main risk factors for the development of aortic aneurysms. Non-rupturing aneurysms are not treated and detected on time and often gradually increase. Most aneurysms are detected during the examination and are small and do not reqanuire surgical treatment. The risk of rupture generally increases with increasing aneurysm diameter. Contrast-enhanced CT is currently the gold standard in the assessment of patients with abdominal aortic aneurysms. It is the most reliable and irreplaceable way, for diagnosis and also for making decisions for the treatment of AAA. Disadvantages of contrast- enhanced CT are the exposure to radiation and the requirement for a contrast agent. The objectives of this retrospective analysis in this paper were to estimate the frequency of abdominal aortic aneurysms in patients who underwent CT angiography examination at the Clinical Department of Radiology at KBC Sušak, in the period from January 1, 2020 to December 31, 2020. During that period, 156 data from patients' medical records were collected. In addition to connect a statistical link between patients with AAA and morphologically normal CT findings (i.e., no signs of aneurysm), this study sought to link gender and age representation among patients with aortic aneurysms.
