Purpose.
To investigate the reproducibility of aortic distensibility (D) measurement using CT and assess its clinical relevance in patients with infrarenal abdominal aortic aneurysm (AAA).
Methods.
54 patients with infrarenal abdominal aortic aneurysm were studied to determine their distensibility by using 64-MDCT.
Aortic cross-sectional area changes were determined at two positions of the aorta, immediately below the lowest renal artery (level 1.) and at the level of its maximal diameter (level 2.) by semiautomatic segmentation.
Measurement reproducibility was assessed using intraclass correlation coefficient (ICC) and Bland-Altman analyses.
Stepwise multiple regression analysis was performed to assess linear associations between aortic D and anthropometric and biochemical parameters.
Results.
A mean distensibility of Dlevel 1.=(1.05±0.22)×10-5 Pa-1 and Dlevel 2.=(0.49±0.18)×10-5 Pa-1 was found.
ICC proved excellent consistency between readers over two locations: 0.92 for intraobserver and 0.89 for interobserver difference in level 1.
and 0.85 and 0.79 in level 2.
Multivariate analysis of all these variables showed sac distensibility to be independently related (R2=0.68) to BMI, diastolic blood pressure, and AAA diameter.
Conclusions.
Aortic distensibility measurement in patients with AAA demonstrated high inter- and intraobserver agreement and may be valuable when choosing the optimal dimensions graft for AAA before endovascular aneurysm repair.
