经皮腔内血管成形术在血液透析患者动静脉瘘血管狭窄中的应用

Application of percutaneous transluminal angioplasty in hemodialysis patients with arteriovenous fistula

目的研究分析经皮腔内血管成形术在血液透析患者动静脉瘘血管狭窄中的应用。方法选取2015年6月~2017年1月期间收治的24例动静脉瘘血管狭窄患者,对全部患者进行经皮腔内血管成形术治疗,观察分析患者经皮腔内血管成形术治疗前后的透析血流量和静脉压变化等情况。结果除了1例患者由于特殊原因没有完成血管扩张术,其余23例患者均完成了血管扩张术,并且取得了良好的效果;而且经过血管扩张之后,患者的透析血流量为(243.6±16.3)m L/min、静脉压为(97.5±14.6)mm Hg、透析充分性Kt/V为(1.33±0.11),都显著优于治疗前,差异具有统计学意义(P<0.05)。结论经皮腔内血管成形术能有效改善血压透析患者的动静脉瘘血管狭窄情况,并且操作简单、无创性,具有较高的临床应用价值。

Objective To study the application of percutaneous transluminal angioplasty in hemodialysis patients with arteriovenous fistula.Methods From June2015to January2017in our hospital,24cases of arteriovenous fistula stenosis were undergoing percutaneous transluminal angioplasty treatment.Then dialysis blood flow and venous pressure changes etc were observed and analyzed before and after the percutaneous transluminal angioplasty treatment.Results In addition to1patients did not complete due to the special vascular dilatation,23patients completed the vascular dilatation and achieved good results;and after vascular dilatation,blood flow of the patients was(243.6+16.3),venous pressure for(97.5+14.6),dialysis adequacy(for1.33+0.11),were significantly better than those before treatment,and the differences were statistically significant(P<0.05).Conclusion Percutaneous transluminal angioplasty can effectively improve the arteriovenous fistula in hemodialysis patients,and the operation is simple,noninvasive,and has high clinical value.
