简要总结
The purpose of this study is to compare the effect of DSA guided percutaneous balloon dilatation, ultrasound guided percutaneous balloon dilatation and surgical repair in the treatment of Stenosis of Arteria-Venous Fistula in Maintenance Hemodialysis Patients.
详细描述
Eligibility Criteria:
- Patients with long-term maintenance hemodialysis with AVF as the vascular access;
- Positive clinical examination signs of AVF stenosis （not all required） : (1) the visual examination: edema, prolonged bleeding time, hematoma, aneurysm or constriction of the fistula .(2) the palpation examination: a narrowing of the outflow vein or aneurysm formation. (3) the auscultation examination: high pitch and/or discontinuous murmur.
- Doppler ultrasound /DSA/magnetic resonance angiography show the diameter of AVF fistula is >50% narrow than the adjacent segment of the fistula lumen.
- Blood flow of the AVF is <500ml/min or monthly declines of the blood flow>25%.
- Patient signed the informed consent.
