“…13,27 In clinical practice, several methods have been proposed to define, grade and evaluate the aneurysm site, with small variations, all of them take into account the following anatomical characteristics: proximal neck evaluation: includes determining morphology (straight, conical, inverted conical, bulging), length, diameter, angle, amount of thrombus, and calcification; aneurysm: the maximum diameter of the AAA is mainly evaluated, whether there are tortuosities, the most acute aortic angle, the amount of thrombus and calcifications; evaluation of the distal neck: diameter and length are mainly measured; and evaluation of common, internal and external iliac arteries. 28 Apart from the analysis of the aneurysm and the aortic necks themselves, which obviously need to be examined, the evaluation of the iliac arteries is of utmost importance and is included in all reports, because when they are poorly formed they can be an exclusion criterion for EVAR. In the presurgical planning protocol it is important to measure the diameter, length, evaluation of the presence of areas of stenosis/occlusion, length of the sealing zone, presence of tortuosities, more acute angles, amount of thrombus and calcification.…”
