Doppler - AV Mapping Both Limbs

Doppler – AV Mapping Both Limbs is a specialized ultrasound examination performed to assess the arteries and veins of both upper or lower limbs, usually before creation of an arteriovenous (AV) fistula for hemodialysis.

This scan uses Doppler technology to evaluate vessel size, blood flow, vein quality, arterial patency, and overall vascular suitability for AV fistula or graft creation. It helps identify the most appropriate vessels for successful dialysis access and reduces the risk of complications.

The test is particularly important for patients with chronic kidney disease (CKD) who may require long-term hemodialysis. It assists vascular surgeons and nephrologists in planning fistula placement and improving long-term dialysis outcomes.

The procedure provides real-time vascular imaging and is safe, non-invasive, painless, and free from radiation exposure.

The purpose of this Doppler – AV Mapping Both Limbs test is to:

• Evaluate arteries and veins in both limbs
• Assess vascular suitability for AV fistula creation
• Measure vessel size and blood flow
• Identify healthy veins and arteries for dialysis access
• Detect vascular abnormalities or blockages
• Assist in dialysis access planning
