使用彩色多普勒血流成像已被证明在预测血液透析患者移植失败方面是有效的，但其对自体动静脉内瘘（AVF）的影响尚不清楚。本研究旨在研究通路血流测量值是否可用作血液透析患者自体AVF早期失效的预测因子。本研究纳入了53例接受自体AVF手术的连续患者。术后1周测量动脉血流量，随访4个月。在随访期间，10例患者在9.8 ± 3.5周时发生了入路失败。失败组（n = 10）的AVF血流量显著低于通畅组（n = 43）（450 ± 214 vs. 814 ± 348 ml/min，p = 0.003）。与流量> 350 ml/min的患者（n = 44）相比，流量<350 ml/min的患者（n = 9）的通路失败发生率更高（55.5% vs. 11.3%，p = 0.008）。失败组的静脉直径显著小于通畅组（3.5 ± 0.5 vs. 4.1 ± 0.7 mm，p = 0.018）。失败组的糖尿病发病率高于未手术组（90 vs. 51%，p = 0.025）。然而，年龄、性别、从手术到首次插管的持续时间以及不同的AVF部位在两组之间没有显着差异。我们的数据表明，在术后早期使用彩色多普勒超声进行通路血流测量是预测血液透析患者自体AVF早期失败的有用参数。
Blood flow imaging using color doppler has proven effective in predicting graft failures in hemodialysis patients, but its effect on native arteriovenous fistulas (AVF) is not well known. This study was performed to investigate whether measurements of the access blood flow can be used as predictors of an early failure of a native AVF in hemodialysis patients. Fifty-three consecutive patients who received native AVF operations were included in this study. Access blood flow was measured at 1 week after operations, and AVF function was followed for 4 months. During the follow-up, access failures developed in 10 patients at 9.8 ± 3.5 weeks. AVF blood flow was significantly lower in the failure group (n = 10) than in the patent group (n = 43) (450 ± 214 vs. 814 ± 348 ml/min, p = 0.003). The incidence of access failures was higher in the patients with a flow <350 ml/min (n = 9) compared to the patients with a flow >350 ml/min (n = 44) (55.5 vs. 11.3%, p = 0.008). The diameters of veins were significantly smaller in the failure group than in the patent group (3.5 ± 0.5 vs. 4.1 ± 0.7 mm, p = 0.018). The incidence of diabetes mellitus was higher in the failure group than in the patent group (90 vs. 51%, p = 0.025). However, age, sex, duration from an operation to first cannulation, and different AVF sites did not make a significant difference between the two groups. Our data suggest that access blood flow measurements using color doppler ultrasound during early postoperative periods are useful parameters in predicting an early failure of a native AVF in hemodialysis patients.
