Objectives: The aortic aneurysm (AO AN) in any segment of the aorta is a disease with potentially severe complications. Thereby, the early diagnosis of AO AN has many advantages. The aim of this paper is to show the capability of TTE in the detection of AO AN. Methods: When the patients’ TTE was completed, the AO had also been examined throughout its length. The ascending and descending AO had been examined from the parasternal window, the arch from the suprasternal and the abdominal AO from the subxiphoid window. The normal value of the diameter of different AO segments is as follows: aortic root and ascending AO: £ 40mm, AO arch: £ 40, thoracic AO and abdominal AO: £ 25mm. The dilatation at every segment of AO was characterized as moderate (aneurysmatic dilatation) and large (aneurysm). For reasons of validity and comparison the patients suffering from AN-AO were also subjected to CT. A correlation with the familiar risk factors had also been performed. The statistical analysis was conducted in Microsoft Excel (test x2). Results-conclusion: From a sample of 2000 patients that had been examined throughout the year, 71 were diagnosed with AN-AO (total 71, male 50, female 21, age 22-90 years old, 64,78MA, SD±13,75 years). From the sample of 71 AN-AO patients, 18,3% were diagnosed with Bicuspid Aortic valve -BAV (total 13, male 8, female 5). The detection of aneurysm at several segments of AO and its relation to BAV is being demonstrated in the following table. Because of the number of our patients was not large enough it was impossible to analyse statistically the relation of each segment of the aorta with each one of the seven investigated risk factors. So we divided our results in two large subdivisions of the aorta. The first part was constituted by aortic root, ascentic aorta, aortic arch and the second by thoracic and abdominal aorta. The results are described in the following tables: [table] As the reader can see in the following table there is not statistical importance (P>0,05) between the six risk factors we examined and the presence of aneurysm in the several parts of the aorta. This is probably due to the small number of patients in some of our groups. The investigation and the collecting of new data is continuing in order to re-examine our data in the future with larger groups. Conclusions: The echocardiography contributes to the diagnose of aneurysms of AO with great precision and therefore should be examined at all its length, especially in cases with risk factors.The patients which are referring to echo laboratory without any motivation, having the above risk factors, have a great possibility of having aneurysm. Echo test can contribute to the daily clinical work as a screening test for the diagnosis of aneurysm. Echo test is simple, safe and non-invasive. Because of CT and NMR tomography have the same findings especially in ascentic and abdominal aorta, CT and NMR are not necessary for the diagnosis and the follow-up of the aneurysm.Following these conclusions we may at this point begin to discuss the term “Echo-aortography”.
