Analysis of the Effect of Ultrasound-guided Percutaneous Transluminal Angioplasty in the Treatment of Autologous Arteriovenous Fistula Stenosis
Objective To explore the effect of percutaneous transluminal angioplasty(PTA)guided by color Doppler ultrasound in patients with autologous arteriovenous fistula stenosis.Methods Clinical data of 82 patients with autolo-gous arteriovenous fistula stenosis admitted to Union Hospital Affiliated to Fujian Medical University from January 2021 to May 2023 were retrospectively selected.According to the vascular access treatment,they were divided into re-construction group(fistula resection and reconstruction treatment,n=22)and PTA group(PTA treatment,n=60).The ultrasound measurement indexes,quality of life,postoperative complications and internal fistula patency were com-pared between the two groups.Results After surgery,the ultrasound indexes and quality of life of the two groups were significantly better than those before surgery,and the PTA group were significantly better than the reconstruction group,the differences were statistically significant(both P<0.05).The total incidence of postoperative complications in PTA group was 6.67%,significantly lower than that in reconstruction group(27.27%),and the difference was statisti-cally significant(χ2=4.604,P<0.05).After surgery,the fistula patency rate in PTA group was slightly lower than that in reconstruction group,and the difference was not statistically significant(P>0.05).Conclusion The results of ultrasound-guided PTA are similar to those of fistula resection and reconstruction,but PTA has the advantages of im-proving patients'quality of life and reducing the incidence of postoperative complications.
