高频彩色多普勒超声在血透患者动静瘘口监测中的应用

The Application of High-frequency Color Doppler Ultrasound in Fistula Monitoring of Hemodialysis Patients

目的探讨高频彩色多普勒超声在血透患者动静瘘口监测中的应用价值。方法采用飞利浦IU22超声仪检测血液透析患者桡动脉和头静脉的狭窄程度、血流量、动静脉内瘘吻合口的内径。结果动静脉内瘘术后,12例患者的头静脉、桡动脉血管狭窄及吻合口内径虽有不同程度降低,血流量仍能达到240 m L/min以上,但不影响患者的血透治疗。22例术后出现不同并发症。结论高频彩色多普勒超声监测血透患者动静瘘口作用显著,适合临床广泛应用。

Objective To investigate the application of High-frequency color Doppler ultrasound in fistula monitoring of hemodialysis patients. MethodsPhilips IU22 ultrasound instrument was used to detect stenosis and blood flow of radial artery and cephalic, and diameter of internal arteriovenous fistula anastomosis. Results After arteriovenous fistulaoperation, stenosis of radial artery and cephalic, and diameter of anastomotic stoma with different degrees for 12 cases, blood flow can reach more than 240 m L/min, but does not affect hemodialysis treatment, complications occurredin 22 cases. Conclusion Highfrequency color Doppler ultrasound was significant in fistula monitoring, fairly suit to be wide used in clinical.
