Doppler - AV Mapping Single Limb
Doppler – AV Mapping Single Limb is a specialized ultrasound examination performed to assess the arteries and veins of one limb, usually before creation of an arteriovenous (AV) fistula for hemodialysis access.
This scan uses Doppler technology to evaluate blood flow, vessel size, 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 minimizes the risk of complications.
The test is especially important for patients with chronic kidney disease (CKD) who may require long-term hemodialysis. It assists doctors and vascular surgeons in planning access placement and improving dialysis outcomes.
The scan provides real-time vascular imaging and accurate assessment of the selected limb’s vascular system.
The procedure is safe, non-invasive, painless, and does not involve radiation exposure.
The purpose of this Doppler – AV Mapping Single Limb test is to:
- Evaluate arteries and veins in one limb
- Assess vascular suitability for AV fistula creation
- Measure vessel size and blood flow
- Identify healthy vessels for dialysis access
- Detect vascular abnormalities or blockages
- Assist in dialysis access planning
