The effect of percutaneous angioplasty on the treatment of poor maturation of the native arteriovenous fistula / 대한내과학회지

ABSTRACT

BACKGROUND: Although percutaneous transluminal angioplasty (PTA) is effective on the treatment of chronic venous stenosis during hemodialysis, its effect on poor maturation of native arteriovenous fistula (AVF) before cannulation is not well known. We evaluated the effect of PTA on the treatment of poor maturation of native AVF before cannulation in hemodialysis patients. METHODS: Venography was performed in 17 patients with poor maturation of native AVF before cannulation. If the stenosis was a 70% or greater decrease in lumen diameter, PTA was performed. RERULTS The incidence of diabetes mellitus was 70.6% (n=12). Of those patients studied, total occlusion was observed in 3 cases, discrete stenosis in 12 cases, no stenosis with multiple accessory veins in 2 cases. Of the 15 patients with stenosis or total occlusion, 9 had such lesions in the proximal vein and 4 at the AV anastomosis and 2 in the artery. Of thirteen of 15 patients with these lesions who underwent PTA, 12 patients initially had successful dilatation and the follow up patency rate at 6.0+/-5.8 months was 61.5%. Two of the patients with restenosis underwent re-PTA with successful dilatation. CONCLUSION: PTA seems to be effective on the treatment of poor maturation of native AVF before cannulation.
