Outcome Measures
Primary Outcomes (1)
patent rate in percentage after PTA
Late luminal loss in patients was evaluated by quantitative angiography after PTA and intravascular ultrasound (IVUS) up to 12 months after PTA. Late luminal loss is defined as the difference between the minimal lumen diameter in percentage and the late luminal loss less than 50% was defined as patency.
1 year
Secondary Outcomes (6)
The incidence of angiography-guided binary restenosis rate (≥50% of the diameter of the reference-vessel)
1 year
The incidence of IVUS-guided binary restenosis rate (≥50% of the diameter of the reference-vessel)
1 year
Change of AVG flow in liter per minute
1 year
Change of AVG pressure in mmHg
1 year

Interventions
Arteriovenous graft (AVG) dysfunction or acute thrombosis is mainly caused by neointimal hyperplasia. Although endovascular intervention, such as percutaneous transluminal angioplasty (PTA), catheter-based directed thrombolysis with urokinase, mechanical thrombectomy with percutaneous thrombolytic device or even if graft stenting, can salvage the hemodialysis access, the long-term primary and secondary patent rate don't improve due to repeated restenosis from neointimal hyperplasia. Drug eluting balloon is used in reducing neointimal hypoplasia in patients with coronary in-stent restenosis and it's also effective in restenosis of peripheral arterial diseases. It's reasonable to hypothesize that PTA with PCB at venous anastomotic stenosis of AVG could prolong the patency and reduce the acute thrombosis rate.
Traditional Plain Balloon was used to dilate the venous anastomotic stenosis of arteriovenous graft (AVG) as the usual intervention
Eligibility Criteria
You may qualify if:
- Aged 18 to 90 years
- Patients under hemodialysis via prosthetic arteriovenous graft in the arm
- Vascular access was created for more than 30 days and used at least one successful session
- Clinical failure for hemodialysis due to higher venous pressure or lower arterial flow
- Angiography proved venous anastomotic stenosis ≥50% (the entire lesion of venous anastomotic stenosis will be extended into AVG no more than 2cm and naive vein no more than 7 cm). There was no other obvious stenosis.
- Reference diameter of venous anastomosis within 7 mm
You may not qualify if:
- Patient could not write informed consent
- Being unwilling or unable to return for follow-up visits or reason to believe that adherence to follow-up visits would be irregular
- Current or scheduled enrollment in other, conflicting studies.
- Acute thrombosis in the past 3 months
- Central venous stenosis
- Concomitant disease (e.g., terminal cancer) or other medical condition likely to result in death within 6 months
- A blood coagulation disorder
- Sepsis or infected arteriovenous access graft
- A contraindication to the use of contrast medium
- Pregnancy
