高血压合并糖尿病患者肾血流变化的彩色多普勒超声观察

Observation on Color Doppler Flow Images of Renal Blood Flow in Cases of Essential Hypertension Complicated with Diabetes

用彩色多普勒血流显像（ＣＤＦＩ）和脉冲多普勒超声心动图（ＰＤＥ）检测１３例肾功能正常的高血压合并非胰岛素依赖型糖尿病（ＥＨＣＤ）患者双侧肾动脉血流，以探讨ＥＨＣＤ患者肾血流动力学改变。ＥＨＣＤ患者与单纯性原发性高血压（ＥＨ）患者相比，肾动脉血流量增多（Ｐ＜０．００１）；与单纯性糖尿病（ＤＭ）患者相比，肾动脉内径缩小（Ｐ＜０．００１），搏动指数（ＰＩ）和阻力指数（ＲＩ）增高（Ｐ＜０．０１）；与对照组相比，肾动脉血流量、ＰＩ和ＲＩ增高（Ｐ＜０．０５），肾动脉内径缩小（Ｐ＜０．０５）。提示，ＣＤＦＩ和ＰＤＥ可为Ｅ－ＨＣＤ、ＥＨ或ＤＭ所致早期肾病，提供一项简易的非创伤性检测方法。

In comparison with essential hypertension (EH), diabetes (DM) and normal cases, in EHCD: ① the volume flow of renal artery was increased; ② the internal diametre of renal artery was decreased with increase of pulsatility (PI); ③ volume flow of renal artery, PI and resistance index (RI) were increased, and the internal diameter of renal artery was decreased respectively.
