Objective: The purpose of our study aimed at evaluating the relationship of type 2 diabetes with longitudinal extension of AAA. Methods: All of 460 AAA patients aged from 41 to 92 years were retrospected in our study, and they were at least twice admitted into our hospital from January 2000 to April 2010. All patients received ultrasound measurement of aorta during each admission. Results: Our results indicated that changes of length of AAA were significantly greater in patients with diabetes than those in patients without diabetes. Type 2 diabetes was associated with length extension of AAA. In subgroup analysis, type 2 diabetes was only related to length change of small AAA rather than large AAA. Diabetes was not an independent risk factor for length extension of small AAA. There was no significant difference of glycosy-lated hemoglobin between diabetes patients and nondiabetes patients. Conclusions: Type 2 diabetes mellitus is closely related to length growth of small AAA, whereas diabetes is not an independent risk factor for length extension of small AAA, and serum glucose under better control could not bring about better result in limiting length extension of small AAA.
