利用彩色多普勒超声对终末期肾病患者人工动静脉内瘘血管的监测

目的：利用彩色多普勒超声监测终末期肾病患者人工动静脉内瘘的血管。方法：应用彩色多普勒超声测定34例终末期肾病患者人工动静脉内瘘血管内径、血流速度、阻力指数（resistent index，RI）、血流量。结果：34例终末期肾病患者中25例内瘘通畅良好，9例出现不同情况的并发症。结论：彩色多普勒超声在终末期肾病患者人工动静脉内瘘的各项指标监测中起重要作用，人工动静脉内瘘口内径在3～7 mm，血流量在350～800 mL/min时，可满足正常血透量。

Using Color Doppler sonography in end-stage renal disease surveillance of artificial blood vessel arteriovenous internal fistula

Objective： The use of Color Doppler sonography monitoring end-stage renal disease artificial vascular arteriove-nous fistula. Methods： 34 cases of Color Doppler sonography in patients with end-stage renal disease artificial arteriovenous fistula vessel diameter, flow velocity, resistance index（RI）, blood flow. Results：34 cases of patients with end-stage renal dis-ease in 25 cases of fistula patency good, there are different situations complications in nine cases. Conclusion： Color Doppler sonography in end-stage renal disease artificial arteriovenous fistula of the indicators play an important role in monitoring , artificial arteriovenous fistula inside diameter 3-7 mm, flow rate at 350-800 mL/min can meet the normal amount of hemodialysis.
