e-flow技术评价尿毒症患者人工动静脉内瘘的价值

目的  探讨超声e-flow血流显像技术评价终末期肾病患者人工动静脉内瘘的临床应用价值。方法  对患有终末期肾病并行人工动静脉内瘘的115例患者，应用e-flow血流显像技术辅以彩色多普勒（CDFI），观察内瘘是否通畅及是否合并相关并发症。结果  超声e-flow技术显示，79例人工动静脉内瘘血流通畅，10例狭窄，18例血栓形成，8例静脉瘤样扩张。e-flow显像技术能同时清晰显示血流和邻近背景组织，与CDFI结合可提高异常图像显示率。结论  e-flow显像技术对监测终末期肾病人工动静脉瘘具有良好的应用价值。

Value of e-flow technique in evaluation of artificial arteriovenous fistula in patients with uremia

Objective To study the clinical value of e-flow imaging in evaluation of artificial arteriovenous fistula. Methods The function of the arteriovenous fistula was measured by e-flow imaging along with routine color Doppler flow image (CDFI) in 115 patients with hemodialysis. Results There were 79 cases of internal fistula patency, 10 cases of stenosis, 18 cases of thrombosis and 8 cases of phlebangioma ectasia. E-flow image clearly displayed blood flow and background tissue at the same time, when combined with CDFI it raised the rate of abnormal image display. Conclusions E-flow imaging is a new and reliable means for diagnosis of artificial arteriovenous fistula.
