The objective of this study was to evaluate hemodynamic variables in arteriovenous fistulas by color Doppler ultrasonography. This study involved 28 patients with chronic renal failure who were sent to surgery clinic for creation of an arteriovenous fistula of the Brescia-Cimino type. Patients were evaluated preoperatively and on the first and seventh days postoperatively by a color Doppler ultrasound machine with a 7.5 MHz linear probe. The distal radial artery was examined preoperatively and the fistula itself postoperatively. Changes in the fistula size and the velocity, volume, and resistive index of the distal radial artery were recorded. Postoperatively the radial artery diameter, systolic flow rates, and volume flow had increased significantly, especially on the first day, in comparison to preoperative values. Resistive index values has decreased significantly at both the first and the seventh days postoperatively. Color Doppler ultrasonography is a very effective method in the evaluation of hemodynamics of arteriovenous fistulas in hemodialysis patients. It will allow an understanding of the pathology in nonfunctioning fistulas or of the cause of complications that develop secondarily.
本研究的目的是通过彩色多普勒超声评估动静脉内瘘的血流动力学变量。本研究纳入了28例慢性肾衰竭患者，他们被送至外科门诊进行Brescia-Cimino型动静脉内瘘造瘘术。术前以及术后第1天和第7天，使用配备7.5 MHz线性探头的彩色多普勒超声仪对患者进行评估。术前检查桡动脉远端，术后检查内瘘本身。记录内瘘大小以及桡动脉远端的速度、容积和阻力指数的变化。与术前值相比，术后桡动脉直径、收缩期流速和容积流量显著增加，尤其是在术后第1天。术后第1天和第7天阻力指数值均显著降低。彩色多普勒超声是评估血液透析患者动静脉内瘘血流动力学的一种非常有效的方法。它有助于了解无功能内瘘的病理情况或继发并发症的原因。
