The study assessed the effectiveness of ultrasound-guided percutaneous transluminal angioplasty (PTA) for treating arteriovenous fistula malfunctions, successfully performed on 4,869 cases between 2004 and 2011.
Early success rates were high, with 97.1% for stenosis cases and 91.9% for obstruction cases, indicating the method's effectiveness.
The procedure showed a low complication rate (0.2%), suggesting that ultrasound guidance is a safe and effective alternative to traditional fluoroscopy-guided techniques.
