Brief Summary

To evaluate the role of DCB angioplasty for venous anastomotic stenosis of hemodialysis graft, investigators would like to perform randomized study comparing the results of drug- coated balloon angioplasty with conventional balloon angioplasty in the treatment in venous anastomotic stenosis of AVG in terms of patency.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Primary patency (Fistulogram can be used for measurement of stenosis)

    6 months

Study Arms (2)

Conventional Balloon Angioplasty

ACTIVE COMPARATOR

Conventional balloon angioplasty. After fistulogram, full expansion of conventional balloon catheter under fluoroscopy guidance in \> 50% venous anastomotic stenosis of hemodialysis graft and ≦4cm from venous anastomosis site in lesion length, confirmed by fistulogram

Device: Conventional Balloon angioplasty

Drug-Coated Balloon Angioplasty

ACTIVE COMPARATOR

Drug-coated balloon angioplasty. After fistulogram, full expansion of drug-coated balloon catheter under fluoroscopy guidance in \> 50% venous anastomotic stenosis of hemodialysis graft and ≦4cm from venous anastomosis site in lesion length, confirmed by fistulogram

Device: Drug-coated Balloon angioplasty

Interventions

After fistulogram, full expansion of drug-coated balloon catheter under fluoroscopy guidance in \> 50% venous anastomotic stenosis of hemodialysis graft and ≦4cm from venous anastomosis site in lesion length, confirmed by fistulogram. Then, participants were divided into two groups (Conventional balloon angioplasty or Drug-coated balloon angioplasty)

Eligibility Criteria

Age19 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age of more than 19
  • Hemodialysis patients with AVG in their arms: Graft should be implanted 30 days ago before enrollment
  • Vascular access actively used for hemodialysis: At least one hemodialysis successful session before enrollment.
  • Clinical signs of access dysfunction: decreased thrill, increased pulsatility, development collateral veins, limb swelling, difficulty in cannulation, prolonged bleeding after hemodialysis, high venous pressure or decreased hemodialysis flow rate during hemodialysis.
  • \> 50% venous anastomotic stenosis of AVG, confirmed by fistulogram (angiography).
  • ≦ 4cm from venous anastomosis site in lesion length
  • Reference diameter \< 7mm of non-stenotic vessel or graft adjacent to venous stenosis.
  • Full expansion of conventional balloon during primary balloon angioplasty, confirmed by fluoroscopy.

You may not qualify if:

  • Patients unable to provide informed consent
  • Patient unable to abide with study follow-up protocol.
  • Patient participating in other relevant or conflicting studies
  • Bare metal stent or stent-graft placed previously
  • Hemodynamically significant stenosis of the central venous system
  • ≧50% stenosis in arterial anastomotic site or venous outflow tract, non including venous anastomosis site
  • Stenosis with a corresponding thrombosis treated within 7 days before enrollment.
  • Limited life expectancy less than 6 months
  • Sepsis or active infection.
  • Recent arm thrombophlebitis (\< 6months).
  • Allergy or other known contraindication to iodinated contrast media, heparin, or paclitaxel
  • Pregnancy or Nursing state
