AV Fistula Doppler

AV fistula Doppler is performed using high-resolution ultrasound imaging on the Mindray Nuewa i9 system, enabling detailed evaluation of vascular access and blood flow dynamics.

AV fistula Doppler study is recommended for evaluation and follow-up of dialysis access:

• Pre-operative fistula mapping

• Post-operative fistula assessment

• Evaluation of fistula maturation

• Reduced flow during dialysis

• Suspected stenosis or thrombosis

• Swelling or pain at fistula site

Common AV Fistula Doppler Studies

• Pre-operative vascular mapping

• Post-operative fistula evaluation

• Maturation assessment

• Flow measurement and surveillance

• Follow-up for complications

🔍 What Does AV Fistula Doppler Assess

• Arteriovenous fistula – patency and flow adequacy

• Arterial inflow – velocity and waveform

• Venous outflow – patency and obstruction

• Stenosis – narrowing at anastomotic or venous segments

• Thrombosis – presence of clot or flow reduction
