规律血液透析患者动静脉内瘘狭窄超声引导下经皮静脉球囊扩张术后的疗效观察

Observation of the effect of ultrasound-guided PTA operation in patients with regular hemodialysis with arteriovenous fistula stenosis

目的:了解超声引导下动静脉内瘘狭窄经皮静脉球囊扩张术(PTA)手术的疗效及影响因素。方法:2018年8月-2020年3月收治规律血液透析动静脉内瘘狭窄患者100例,随机分为两组。对照组规律血液透析,内瘘成熟并正常使用;观察组规律血液透析,患者动静脉内瘘狭窄在超声引导下行PTA手术。比较两组血管内径、血管内自然血流量、透析穿刺针血流量、手术疗效、PTA术后使用时间。结果:观察组术后血管内径、血管内自然血流量、透析穿刺针血流量明显优于术前,差异有统计学意义(P<0.05)。观察组手术成功率较高,并且内瘘通畅率也较高,且术后并发症发生率较少。结论:超声引导下动静脉内瘘狭窄PTA手术操作简单,术后即可透析。

Objective:To understand the efficacy and influencing factors of PTA surgery for arteriovenous fistula stenosis under ultrasound guidance.Methods:From August 2018 to March 2020,100 patients with regular hemodialysis arteriovenous fistula stenosis were selected,they were randomly divided into the two groups.In the control group,regular hemodialysis fistulas were mature and used normally.In the observation group,regular hemodialysis patients with arteriovenous fistula stenosis underwent ultrasound-guided PTA surgery.The inner diameter of the blood vessel,the natural blood flow in the blood vessel,the blood flow of the dialysis puncture needle,the curative effect of the operation,and the use time after PTA were compared between the two groups.Results:After operation,the vascular diameter,the natural blood flow in blood vessels and the blood flow of dialysis needle of observation group were significantly higher than those before operation,the differences were statistically significant(P<0.05).The success rate of operation and the patency rate of internal fistula in the observation group were better,while the incidence of postoperative complications was less.Conclusion:Ultrasound-guided PTA surgery for arteriovenous fistula stenosis is simple and can be dialysis after operation.
