Objective Color doppler flow imaging ( CDFI) was used to evaluate the effects of difficult arteriovenous fistula establishment for hemodialysis. Methods CDFI was used to monitor the establishment of blood vessel in Hemodialysis and estimate diameter of the vessels. CDFI was applied to select appropriate artery and vein before operation for arteriovenous fistula, and to analyze hemodynamic status and complications after operation in 176 patients with arteriovenous fistula which was difficult to establish in clinic for hemodialysis. Results Operations for establishing fistula were performed for the 176 cases and for 19 cases with subsequent intercurrent complications. Conclusion CDFI ultrasound could play important roles in choosing appropriate artery and vein before operation for arteriovenous fistula, and analyzing of hemodynamics and complications after operation.%目的 探讨彩色多普勒超声在临床建立前臂动静脉内瘘较为困难的血液透析患者中的价值.方法 用彩色多普勒超声监测176例终末期肾病患者血液透析通路建立前、后的超声表现,术前利用超声选择适宜吻合的动、静脉,扫查有无变异及合并症,描记其走行,确定吻合部位,检测桡动脉和头静脉的通畅程度,测量其内径、血流平均速度,造瘘术后评价动静脉内瘘,测量内瘘口血流速度、动静脉内血流情况与伴随合并症,并对部分并发血栓患者溶栓后进行监测.结果 176例终末期肾病行前臂人工动静脉内瘘患者,术前超声选择、测量并定位,评价血管情况,术后4～8周内复查,157例患者通路通畅,19例出现合并症(其中7例为2次或以上造瘘),其中12例行局部尿激酶溶栓治疗后,9例瘘管再通.结论 彩色多普勒超声在血液透析患者建立动静脉内瘘中对术前血管的选择、吻合口部位的确定以及造瘘术后评价动静脉内瘘及分析内瘘合并症、相应血管血流情况有重要作用.
