**10. Conclusion** 

Infrarenal segment of aorta in patients with AAA is a nondilated part. However, the fact that infrarenal segment of aorta in all the subject of Asian population was significantly wider than transverse diameter of control subjects, and additionally, that it is related to the neck which is not dialated in transverse diameter, leads to conclusion that AAA patients in general have wider aneurysmatic neck than infarenal segment of control subjects (with discrete aortic dilatation or normal findings). Furthermore, the width of this segment may be disposing factor for the development of AAA or/and vice versa, that the development of

Most of the studies showed that the diameter of abominal aorta aneurysm grows for 0,08 cm annually, so the most accurate conclusions could be obtained by comparing subjects of the

Asian population with the presence of aneurysm had significanty higher following diameters F.d. a.i.c. 2-6 i R-d. a.i.c. 1-6. compared to controls, while in F.d. a.i.c 1 there was no significant difference. The most prominent result was found in the transverse diameters F.d. a.c.i 1 of patients and controls. This was the only parameter where there was no difference in patients and controls of the Asian population, while in Caucasian there was a border-line difference. The exact place is just above the bifurcation, where depending on the bifurcation angle, there is a different flow gradient that correlates with the angle of bifurcation, which is lower in the population of yellow race. Additionally, there is a subtle difference between the blood flow velocity of the aorta and proximal parts of iliac arteries. The changes in the vessel wall, as well as propagation of the aneurysm from aorta to iliac

In the preprocedural evaluation of EVAR method, nowadays the use of separate workstation is common. It is often used by vascular surgeons in order to obtain 3D visualization and measuring in individual case, for precise planning and choice of suitable type and dimensions of the graft. Actually, they use specially developed software applications on Windows platform, which are suitable for personal computers; widely
