Abstract

The aim of the study was to investigate the effectiveness of ultrasound in the evaluation of percutaneous balloon angioplasty (PTA) for the treatment of autogenous arteriovenous fistula (AVF) stenosis. 40 patients with AVF stenosis participated in the study who were treated with regular hemodialysis in the First Hospital of Jilin University. Among the many indicators, we selected radial blood flow, radial artery resistance index, and anastomotic diameter as monitoring indicators. The results of preoperative, immediate postoperative, postoperative 1 day, 3 days, 7 days, and 14 days were used to find the trend of the indicator and determine the best monitoring time point. Finally, we found morphological indicators and hemodynamic parameters changed significantly after operation; no obvious statistical difference between 1 day postoperative and other postoperative monitoring time points were founded. So, ultrasonography has unique advantages in hemodynamics and morphological examination. It can evaluate the functional status of AVF and the efficacy of PTA accurately, and we believe that the first day after surgery is the best time to monitor.

球囊成形术治疗自体动静脉瘘吻合口狭窄的超声评价:PTA治疗AVF吻合口狭窄的超声评价

本研究的目的是探讨超声在评估经皮球囊血管成形术(PTA)治疗自体动静脉瘘(AVF)狭窄中的有效性。本研究选取了40例在吉林大学第一医院接受常规血液透析治疗的AVF狭窄患者。在众多指标中，我们选择桡动脉血流、桡动脉阻力指数和吻合口直径作为监测指标。利用术前、术后即刻、术后1天、3天、7天、14天的结果，寻找指标的变化趋势，确定最佳监测时间点。最后，我们发现术后形态学指标和血流动力学参数有明显变化;术后1天与术后其他监测时间点无明显统计学差异。因此，超声检查在血流动力学和形态学检查方面具有独特的优势。可以准确评价AVF功能状态及PTA疗效，我们认为术后第一天为最佳监测时间。
