Abstract:
Objective To study the changes of flow parameters of superior mesenteric artery (SMA) in children with abdominal type Henoch-Schonlein purpura (HSP) using color Doppler ultrasound.Methods Ten children with abdominal type HSP and 17 controls were included in present study.The blood flow parameters of SMA[including peak velocity(PV),end-diastole velocity(EDV),resistant index(RI)]were measured at acute and recovery stage separately.Statistical analysis was conducted among groups.Results PV were (41.57±8.02)cm/s,(33.38±7.44)cm/s and (35.34±9.73)cm/s in acute stage,recovery stage and control group,respectively.There was no statistically significant difference among groups(F=2.471,P=0.10).EDV were(7.63±4.28)cm/s,(4.23±2.57)cm/s and (3.77±0.87) cm/s in acute stage,recovery stage and control group,respectively.There was significantly significant differences between acute stage group and other two groups(t=0.066,P=0.025;t=0.059,P=0.003).RI were (0.85±0.17),(1.00±0.15) and (1.04±0.13) in acute stage,recovery stage and control group,respectively.Also there was significantly significant differences between acute stage group and other two groups(t=1.391,P=0.020;t=1.239,P=0.026).Conclusion For abdominal type HSP in children,the changes of PV,EDV and RI of SMA were significant,which may help us determine the stage of disease.
