High-frequency Ultrasound Evaluation of Carotid Artery Function Changes in End-stage Renal Disease Patients / 医学研究杂志

ABSTRACT

Objective To investigate the change of the carotid artery function in the end-stage renal disease(ESRD)patients using high-frequency ultrasound.Methods 60 cases(30 cases of hemodialysis patients,30 cases of non-dialysis patients)of ESRD patients and 30 cases of control persons with normal renal function were checked by the high-frequency color Doppler ultrasonography.Two-dimentional ultrasound was used to observe the intima-mediathickness(IMT);M-mode ultrasound was used to record the movement extent change between systolic and diastolic period of the anterior and the posterior wall of common carotid artery;the diameters of systolic and diastolic period,the stiffness index,distensibility and compliance,acceleration and deceleration which were corrected with pluse pressure and heart rates(ACi and DCi),were calculated.Results Compared with the control group,the ESRD groups have thicker IMT,higher stiffness index,lower disensibility,compliance,ACi and DCi in each ESRD group(?0.05).IMT correlated with stiffness index,distensibility,compliance,ACi and DCi.Conclusion High-frequency ultrasound plays an important role in evaluating change of the carotid artery function in ESRD patients.
