Abstract

Purpose: To assess the effect of abdominal aortic aneurysm (AAA) sizeon overall aneurysm morphology with special attention to possible relationships among various anatomic variables that determine the feasibility of endovascular repair. Methods: One hundred sixty-eight patientswere assessed with spiral computed tomographic angiography to measurethe length and diameter of the AAA, the proximal neck, and the commoniliac arteries. Anatomic variables were correlated with aneurysm sizeusing Spearman's rank order correlation coefficients irs); comparisons among small, intermediate, and large aneurysms were made using the Chi-square test. Results: Correlations between aneurysm size and the anatomic variables above were weak. The strongest association was between aneurysm size and aortic length (r(S) = 0.41, p < 0.001). Subgroup analysis showed no difference in proximal neck length, neck diameter, or overall suitability for endovascular repair between aneurysms greater or smaller than 5.5-cm diameter. However, significantly more short (< 1.5 cm), wide (> 3 cm), and, hence, unsuitable proximal necks were found in patients with aneurysms > 7 cm in diameter (chi(2) = 7.8, p < 0.01). Conclusions: Shortening and widening of the proximal neck seemsto increase with aneurysm size but only after the aneurysm expands beyond 7 cm in diameter. Aneurysms with diameters in the 4.5- to 5.5-cm range are no more suitable for endovascular repair than those between 5.5 and 7 cm. The lack of any significant correlation between anatomicvariables emphasizes the need for accurate preoperative assessment ofthe anatomy of each individual patient before endovascular repair.
