PTA术后动静脉内瘘可视化B超穿刺的效果评价 Evaluation ofthe visualized B-ultrasound-guided puncture for [摘要] 目的对比常规盲穿组与可视化B超引导下穿刺球囊扩张术后动静脉内瘘的应用效果 方法选取2018年11月——2019年11月在本院行规律透析内瘘狭窄行球囊扩张术后患者140名，随机分成可视化B超引导下穿刺组和常规盲穿刺组各70例。记录两组病人术后内瘘内径及随访3个月、6个月、9个月内瘘相关远期并发症，比较两种方法穿刺效果以及穿刺相关并发症发生率情况。 结果可视化B超引导下穿刺与常规盲穿组相比较，可视化B超穿刺组穿刺相关近期并发症：穿刺点硬结、穿刺处渗血、皮下血肿发生率明显低于常规穿刺组（p小于0.05），差异有统计学意义。记录两组病人PTA术后内径及随访3个月、6个月、9个月内瘘远期并发症：内瘘狭窄、内瘘闭塞、假性血管瘤发生率比较差异有统计学意义（p小于0.05）。 结论可视化B超引导对球囊扩张术后动静脉内瘘穿刺效果明显优于常规盲穿组穿刺组，能提高穿刺成功率，降低穿刺近远期相关并发症并提高患者满意度，进一步保护球囊扩张术后动静脉内瘘功能，满足病人持续血液透析的需要。 [Abstract] Objective：To compare the application effect of the conventional blind puncture group and the visualized B-ultrasound-guided puncture balloon dilatation group in the treatment of arteriovenous fistula Methods：From November 2018 to November 2019, 140 patients with regular dialysis internal fistula stenosis underwent balloon dilatation in our hospital were randomly divided into two groups: visual B-ultrasound-guided puncture group and conventional blind puncture group.Internal fistula diameter was recorded in two groups The long-term complications related to internal fistula were followed up for 3, 6 and 9 months, the results of the two methods and the incidence of complications were compared. Result:Compared with the conventional blind puncture group, the near-term complications of puncture in the visual B-ultrasonic puncture group were as follows: induration of puncture point, bleeding at puncture point and hematoma under the skin,whose incidence was significantly lower than that of routine puncture group (P < 0.05). The internal diameter of patients in two groups after PTA was recorded.And follow-up 3 months, 6 months, 9 months long-term complications of internal fistula: internal fistula stenosis, internal fistula occlusion, pseudohemangioma incidence were statistically significant (P < 0.05). Conclusion:Visual B-ultrasound guidance is superior to the conventional blind puncture group in the puncture effect of arteriovenous internal fistu
