摘　　要：目的探讨肾移植和血液透析患者颈动脉扩张性的临床意义。方法利用高频超声,通过彩色流速流量定量技术测量60例肾移植患者和42例血液透析患者及30例正常人颈动脉的收缩期和舒张期内径,计算颈动脉的扩张系数和僵硬度。所有受试者的血压都小于140/90mmHg(1mmHg=0.133kPa,下同)。结果移植时间在6个月～24个月的肾移植患者和相同透析时间的透析患者相比,前者颈动脉扩张系数明显增大,僵硬度明显减低(P<0.01)。透析时间小于24个月的血液透析患者与正常对照组相比,扩张系数明显减低,动脉僵硬度明显增加。结论血液透析较肾移植患者和正常受试者的动脉壁弹性减低。Objective To evaluate carotid artery distensibility in patients with kidney transplantation and hemodialysis. Methods Systolic and diastolic diameters of carotid artery in 60 patients with kidney transplangtation, 40 patients with hemodialysis and 30 control subjects were measured using high frequency ultrasound, and the distensibility coefficient of carotid artery was calculated. The arterial blood pressure of all patients was 〈140/90 mm Hg. Results The univariate analysis between the two groups indicated that distensbility coefficient and stiffness degree of the carotid artery in renal transplant recipients and dialysis patients were very significantly different. Conclusions The elastic properties of arterial wall in dialysis patients are decreased, compared dialysis patients with renal transplant recipients and control subjects.
