Objective: Dilatation of common carotid artery (CCA) has been indicated as an independent risk factor for thoracic and abdominal aortic aneurysm (AA); however, it has not been yet established in Japanese patients with AA. This study aimed to identify CCA diameter of preoperative patients with AA.

Material and Methods: We evaluated 40 AA patients and 40 controls. External and internal diameters of bilateral CCA during diastolic phase were measured in each group. Mann-Whitney U test was used to compare differences between two groups, and receiver operating characteristic curve (ROC) was used to evaluate optimal sensitivity and specificity for diagnosing the co-morbidity of AA.
