The effect of Roux-en-Y gastric bypass (RYGB) on carotid intima-media thickness (C-IMT) in obese patients with type 2 diabetes (T2D) has not been well studied.
To investigate the effect of RYGB on C-IMT and the relationship between C-IMT and some cardiovascular risk factors 12 months after surgery on Chinese obese patients with T2D.
University hospital, China.
Thirty-three consecutive obese patients with T2D and 18 healthy volunteers matched in age and sex were enrolled in this retrospective study. The anthropometric data, metabolism variables, and C-IMT were recorded before and 12 months after RYGB.
The patient group had significantly higher C-IMT than the control group before surgery (589.5±96.9 μm versus 457.9±48.6 μm, respectively; P<.01). C-IMT had significant positive relationships with age, body mass index, systolic blood pressure, visceral fat area (VFA), and serum leptin (r = .56, .44, .38, .42, and .38, respectively; P<.01). Twelve months after RYGB, the anthropometric data, metabolism variables, and C-IMT had improved significantly. The change in C-IMT was positively correlated with changes in VFA and leptin level (r = .39 and .36, respectively; P<.01).
RYGB surgery seems to be effective on C-IMT for obese patients with T2D in China. VFA and leptin level are related to improvement of C-IMT.
Roux-en-Y 胃旁路术（RYGB）对 2 型糖尿病（T2D）肥胖患者颈动脉内膜中层厚度（C-IMT）的影响尚未得到很好的研究。
探讨 RYGB 对 C-IMT 的影响以及 C-IMT 与术后 12 个月中国肥胖 T2D 患者一些心血管危险因素的关系。
中国大学医院。
这项回顾性研究纳入了 33 例连续肥胖 T2D 患者和 18 例年龄和性别相匹配的健康志愿者。记录了 RYGB 前后的人体测量数据、代谢变量和 C-IMT。
术前患者组的 C-IMT 明显高于对照组（589.5±96.9μm比 457.9±48.6μm，P<.01）。C-IMT 与年龄、体重指数、收缩压、内脏脂肪面积（VFA）和血清瘦素呈显著正相关（r =.56，.44，.38，.42 和.38，P<.01）。RYGB 术后 12 个月，人体测量数据、代谢变量和 C-IMT 均显著改善。C-IMT 的变化与 VFA 和瘦素水平的变化呈正相关（r =.39 和.36，P<.01）。
RYGB 手术似乎对中国肥胖 T2D 患者的 C-IMT 有效。VFA 和瘦素水平与 C-IMT 的改善有关。
