Carotid intima media thickness (CIMT) is a surrogate maker of subclinical atherosclerosis. The aim of this study is assessment of relationship between CIMT and infra-renal abdominal aorta diameter in women with and without Gestational Diabetes Mellitus.</p> <p><strong>Materials and Methods</strong><strong>: </strong>The current case-control study was conducted in department of radiology of Shahid Sadoghi hospital in Yazd medical science university 2012 to 2013. Forty women between 20-40 years old with at least 6 months after pregnancy were enrolled, 20 participants with GDM in last pregnancy and 20 participants without history of GDM. All participants underwent physical exam and laboratory findings. Finally Carotid intima-media thickness and infra abdominal aorta diameter were obtained.</p> <p><strong>Results</strong><strong>: </strong>over all comparison between GDM and non GDM groups revealed no significant difference in mean CIMT and infra-renal abdominal aorta diameter. FBS between two groups reveal significant statistically difference (<em>P</em>-value<0.05). Also Pearson correlation analysis shows association between infera-renal abdominal aorta diameter and cholesterol and LDL in non GDM participate.</p> <p><strong>Conclusion: </strong>Our study suggested GDM may not relate to CIMT and infera-renal abdominal aorta diameter. Also current study revealed women with history of GDM are prone to having impaired fasting glucose.</p> Carotid intima-media thickness, Gestational diabetes mellitus, Infra-renal abdominal aorta diameter 50 54 http://ijdo.ssu.ac.ir/browse.php?a_code=A-10-30-105&slc_lang=en&sid=1 Reza Nafisi-Moghadam No MD, Department of Radiology, Faculty of Medicine, Shahid Sadoughi University of Medical Sciences Yazd, Iran Nasim Namiaranian No MD, Community Medicine Specialist Yazd Diabetes Research Center, Shahid Sadooghi University of Medical Sciences, Yazd, Iran Maryam Karbasi No Hashem Hojat No MD, Department of Radiology, Faculty of Medicine, Shahid Sadoughi University of Medical Sciences Yazd, Iran Sied Kazem Razavi Ratki Yes MD, Department of Radiology, Faculty of Medicine, Shahid Sadoughi University of Medical Sciences Yazd, Iran
