ABSTRACT
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 (P0.05). 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.
