经皮腔内血管成形术治疗自体动静脉内瘘狭窄术后通畅率及影响初级通畅因素分析

Analysis of patency rate and primary patency factors after percutaneous transluminal angioplasty for autogenous arteriovenous fistula stenosis

目的探讨经皮腔内血管成形术(PTA)治疗血液透析患者自体动静脉内瘘狭窄术后通畅率及影响初级通畅因素分析。方法选取新疆克拉玛依市中心医院2014年8月至2018年8月因动静脉内瘘狭窄首次行PTA治疗的患者34例,计算PTA术后3、6、12个月初级通畅率,并对影响PTA术后动静脉内瘘初级通畅因素进行相关性分析。结果34例患者PTA手术成功率为91.2%(31/34),术后3、6、12个月的动静脉内瘘初级通畅率分别为90.3%、80.6%、64.4%。残留狭窄、狭窄长度>3cm是影响PTA术后动静脉内瘘初级通畅的独立危险因素。结论PTA治疗动静脉内瘘狭窄手术成功率高,短中期效果良好,残留狭窄、狭窄长度是影响PTA术后初级通畅率的重要因素。

Objective To investigate the patency rate and the influencing factors of primary patency after percutaneous transluminal angioplasty(PTA).Method From August 2014 to August 2018,34 patients who were first treated with PTA due to arteriovenous fistula stenosis in Karamay Central Hospital of Xinjiang were selected to calculate the primary patency rate at 3 months,6 months and 12 months after PTA,and the influencing factors of patency time of internal fistula after PTA were analyzed.Result The success rate of PTA was 91.2%(31/34),and the primary patency rate was 90.3%,80.6%and 64.4%at 3,6 and 12 months after PTA.Residual stenosis and stenosis length>3 cm were independent risk factors for primary patency after PTA.Conclusion PTA has a high success rate in the treatment of arteriovenous fistula stenosis,with good effect in the short and medium term.Residual stenosis and stenosis length are important factors affecting primary patency after PTA.
