Aim: The hypothesis of this multicentric study is performing a specific typification in the selection of grafts for the endoluminal treatment of an aneurysmally altered distal aorta based on mathematical information and the correlation of a number of morphological parameters diagnosed by 64-multidetector computed tomographic (CT) aortography.

Materials and Methods: The study is multicentric and encompassed 30 Asian and 30 European patients. Examinations were performed on the same type of 64- multidetector CT equipment and under same conditions of examination technique and postprocessing. Several statistical methods were applied to analyze the results.

Results: Statistically significant differences were found between Asian and European patients in the morphology of the central part of the aneurysm at the level of the abdominal aorta and the width and length of the iliac arteries. The principal cause of the most frequent complication observed was defined by a CT aortographic study.

Conclusions: Computed tomographic aortographic quantification of significant parameters makes it possible to plan the exact dimensions of grafts in each individual case. Computed tomographic examinations make possible very exact measurements and positioning of the graft of the novel design proposed by the authors and expected to substantially reduce the incidence of complications.
