| 目的 通过彩色多普勒技术测量尿毒症腹膜透析(PD)患者、尿毒症非PD患者及正常健康人肠系膜上动脉(SMA)血流动力学参数,探讨PD对尿毒症患者SMA血流动力学的影响。方法 应用Philips飞凡型彩色多普勒超声诊断仪对尿毒症PD患者、尿毒症非PD患者及健康志愿者各30例进行SMA血流动力学参数测量。结果 三组间收缩期峰值流速(PSV)、管径(D)差异无统计学意义(P>0.05);尿毒症PD组阻力指数(RI)、搏动指数(PI)低于对照组及尿毒症非PD组,差异有统计学意义(P<0.05),而尿毒症非PD组与对照组间RI、PI差异无统计学意义(P>0.05);尿毒症PD组舒张末期流速(EDV)、时间平均流速TAVM、血流量Q高于对照组及尿毒症非PD组,差异有统计学意义(P<0.05),而尿毒症非PD组与对照组间EDV、TAVM、Q差异无统计学意义(P>0.05)。 尿毒症PD组RI、PI与PD龄呈负相关(r=－0.91, P<0.05; r=－0.66, P<0.05)。结论 彩色多普勒超声可以无创地评价尿毒症PD患者SMA血流动力学情况,其中RI、PI的下降对于PD患者SMA血流动力学损害有重要提示意义。 |

| Objective To investigate the changes of hemodynamic parameters of superior mesenteric artery (SMA) during peritoneal dialysis (PD). Methods Thirty uremic patients with PD (PD group), 30 uremic patients without PD (non-PD group) and 30 healthy subjects (control group) were enrolled. All cases underwent Doppler ultrasonography and the hemodynamic parameters were obtained. Results The peak systolic velocity (PSV) and diameter (D) were not statistical different among three groups (P>0.05). The resistance index (RI) and pulsatility index (PI) decreased in PD group compared with the other two groups (P>0.05), but no difference was found between non-PD group and control group (P>0.05). The end-diastolic velocity (EDV), time-averaged velocity (TAVM) and blood flow (Q) were higher in PD group than those in non-PD group and control group (P<0.05). No difference of EDV, TAVM and Q was found between the control group and non-PD group (P>0.05). PI and RI were negatively correlated with PD time (r=－0.91, P<0.05; r=－0.66, P<0.05). Conclusion Color Doppler ultrasound can non-invasively evaluate PD through hemodynamic changes of SMA. |
