肾综合症出血热病程中肾动脉血流动力学的彩色多普勒研究

Hemodynamic Study of Color Doppler Flow Imaging on Renal Arterial During Hemorrhagic Fever with Renal Syndrome

目的 :观察肾综合症出血热 (HFRS)病程中肾动脉血流动力学变化。材料与方法 :用彩色多普勒超声诊断仪检测了 30例正常人和 5 9例经血清学证实的HFRS患者 ,测定病程中少尿期 ,移行期 ,多尿期肾动脉的血流频谱参数。结果 :三期肾动脉Vs与正常对照组比较均未见统计学意义 (P >0 0 5 ) ,少尿期、移行期、多尿期Vd、Vm明显低于正常组 (P <0 0 1) ,RI明显高于正常组 (P <0 0 1)。少尿期、移行期肾动脉血流量明显低于对照组 (P <0 0 1)。结论 :HFRS病程中 ,三期肾动脉RI,Vd、Vm随病情进展有明显规律性。Vm、Vd、Q逐渐增高 ,RI逐渐降低。肾动脉血流频谱参数能反映出HFRS病程的变化 ,对病情发展 ,治疗效果的监测 。

Purpose:To observe on renal hemodynamics during hemorrhagic fever with renal syndrome.Materials and Methods:The blood flow spectrum of oligourinary,transitory and polyurinary stages were measured in 59 cases of serologically proved HFRS and 30 normal subjects using color doppler ultrasonography.Results:in oligourinary?transitory and polyurinary stages,Vs was not statistically different from that in the control group (P< 0 05),But the Vd?Vm were remarked lower than those of the normal group (P<0 01).The resistant indexes (RI) were significantly different as compared with those of the normal group.The renal arterial Q was remarked lower than those of the normal group (P<0 01) in oligourinary transitory.Conclusions:in different stages of the disease the change of Vm?Vd?Q and RI of renal arteries have prominent regularity.The Vm?Vd and Q were increased and the RI was decreased.The blood spectra of renal arteries can illustrate the stage change of the disease.It can provide diagnosing bases for monitor the course of the disease,treatment and the patient's prognosis.
