摘　　要：目的通过肾移植后患者颈动脉扩张性的研究,探讨其变化规律及临床意义。方法应用彩色流速流量定量技术测量65例肾移植患者和30例正常人颈动脉的收缩期和舒张期内径,计算颈动脉的扩张性系数和僵硬度。要求所有受试者的血压都小于140/90 mm Hg（1 mm Hg=0.133 kPa）。结果方差分析显示,移植时间小于6个月的肾移植患者和正常受试者的颈动脉扩张性系数存在明显统计学差异（P=0.017）;随着移植时间的延长,肾移植患者的颈动脉僵硬度逐渐降低。肾移植患者的颈动脉扩张性系数和脉压呈显著线性相关（r=-0.556,P=0.002）。结论随着移植时间的延长,肾移植患者的颈动脉扩张性是好转的。Objective To evaluate carotid artery distensibility in patients with kidney transplantation. Methods Systolic and diastolic diameter of carotid artery in 60 patients with kidney transplantation and 30 control subjects were measured using high-frequency ultrasound, and calculating distensibility coefficient of carotid arter- y. The arterial blood pressure of all patients was〈140/90 mm Hg. Results The univariate analysis between two the groups indicated that distensibility coefficient of carotid artery of renal transplant recipients with transplantation time before six month and healthy subjects was very significantly different. With the prolonging of transplantation time, carotid artery stiffness degree was gradually decreased. The linear correlation between carotid artery distensibility coeff cient and pulse pressure was significant （r=-0. 556, P=0. 002） . Conclusions With the prolonging of transplantation time, carotid artery distensibility of renal transplant recipients was improved.
