摘 要: | 目的:观察流行性出血热(EHF)病程中各级肾动脉血流动力学变化。方法:用彩色多普勒超声诊断检测了40例正常和51例经血清学证实的EHF患者,测了病程中各期肾门部肾主动脉、段动脉、叶间动脉、弓形动脉的血流频谱参数。结果:发热期、恢复期各级肾动脉血流频谱各项参数与正常对照组比较,均未见统计学差异(P>0.05)。少尿期、移行期、多尿期各级肾动脉低于正常对照组(P<0.01)。Vd、Vs、Vd/Vs在少尿期、移行期明显低于对照组(P>0.01)在多尿期,叶间动脉和弓形动脉低于对照组(P<0.05)。结论:EHF病程各期各级肾动脉RI、Vd、Vs、Vd/Vs随病情变化有明显规律性。从少尿期到恢复期RI逐渐降低,Vd、Vs、Vd/Vs逐渐增高。肾动脉血流频谱参数能准确反应EHF病程的变化,对监控病情是有意义的。

Observation on All Renal Arterial Hemodynamics During Epidemic Hemorrhagic Fever Using Color Doppler Ultrasonography |

Abstract: | Objective:To observe on all renal arterial hemodynamics during epidemic hemorrhagic fever(EHF).Methods:The blood flow spectrum of main renal arteries,segmental arteries,interlobar arteries and arcuate arteries were measured in 51 cases of serologically proved EHF and 40 normal subjects using color Doppler ultrasonography.Results:In febrile and recovery stages renal hemodynamics of the blood flow spectra was not statistically different from that in the control group(P>0.05).The resistant indexes(RI)of all the renal arteries were increased significantly as compared with those of the normal group in oligourinary,transitory and polyurinary stages(P<0.01).In oligourinary and transitory stages,the Vd,Vs and Vd/Vs were remarkedly lower than those of the normal group(P<0.01),while in the polyurinary stage,Vd,Vs and Vd/Vs of interlobar and arcuate arteries were lower than those of the normal group(P<0.05).Conclusions:In different stages of the disease,the changes of RI,Vd,Vs and Vd/Vs of renal arteries have prominent regularity.From the oligourinary to the recovery stage,the RI was decreased while the Vd,Vs and Vd/Vs were increased.The blood spectra of renal arteries can accurately illustrate the stage changes of the disease.This is valuable for us to monitor the course of the disease. |
