AV Fistula Mapping

At Dr. Dere Sonography & X-Ray Centre, AV Fistula Mapping is performed by Dr. Sameer Dere, Consultant Radiologist with extensive expertise in Vascular and Diagnostic Ultrasound Imaging. Using advanced Color Doppler technology, every examination provides accurate measurements of arteries and veins, helping vascular surgeons and nephrologists plan the ideal site for AV fistula surgery.

AV Fistula Mapping plays an essential role in patients with chronic kidney disease (CKD) who require long-term hemodialysis. By carefully evaluating blood vessel size, blood flow, vessel quality, and anatomical variations, the examination improves the chances of creating a well-functioning dialysis fistula while minimizing the risk of surgical failure.

Whether you are preparing for your first dialysis access procedure, require a repeat fistula after previous failure, or need evaluation before vascular access surgery, AV Fistula Mapping provides valuable diagnostic information that supports successful treatment planning.

AV Fistula Mapping provides comprehensive assessment of the arteries and veins of the upper limbs to determine their suitability for dialysis access creation.

• Pre-operative assessment before AV fistula creation.
• Evaluation of artery diameter and blood flow.
• Assessment of vein size and patency.
• Detection of venous thrombosis or obstruction.
• Identification of arterial narrowing or disease.
• Assessment of vessel wall quality.
• Detection of anatomical variations.
• Planning for repeat AV fistula surgery.

Signs & Symptoms That May Require AV Fistula Mapping

AV Fistula Mapping is recommended for patients with chronic kidney disease who require long-term hemodialysis. It helps evaluate the arteries and veins before surgery, ensuring the best possible vascular access and improving the long-term success of the AV fistula.

• Advanced Chronic Kidney Disease (CKD) requiring hemodialysis.
• Planning for first-time AV fistula creation.
• History of previous failed AV fistula.
• Previous upper limb vascular surgery.
• Suspected narrowing or blockage of upper limb blood vessels.
• Need for repeat vascular access surgery.
• Pre-operative evaluation before AV graft placement.
• Assessment before permanent dialysis access creation.
• Routine vascular mapping whenever advised by your nephrologist or vascular surgeon.

What Does AV Fistula Mapping Assess?

AV Fistula Mapping provides a detailed evaluation of the arteries and veins of the upper limbs. It measures vessel size, blood flow, and vessel quality while identifying any abnormalities that may affect successful AV fistula creation.

Arterial Assessment

The arteries of the upper limb are examined for diameter, blood flow, vessel wall quality, calcification, narrowing, and other abnormalities to determine whether they are suitable for AV fistula creation.

Venous Assessment

The superficial and deep veins are evaluated for diameter, patency, compressibility, blood flow, thrombosis, and overall suitability for creating a durable dialysis access.

Blood Flow Evaluation

Advanced Color Doppler technology measures blood flow velocity and direction within both arteries and veins, ensuring adequate circulation for a well-functioning AV fistula.

Vessel Diameter Measurement

Precise measurements of arteries and veins help determine the most appropriate site for AV fistula creation and increase the likelihood of successful maturation.

Detection of Vascular Abnormalities

The examination identifies arterial narrowing, venous obstruction, thrombosis, anatomical variations, and other vascular conditions that may interfere with dialysis access surgery.

Pre-Surgical Planning

Detailed vascular mapping assists nephrologists and vascular surgeons in selecting the best artery-vein combination for successful AV fistula surgery.

Assessment After Previous Access Failure

Patients with previously failed AV fistulas benefit from repeat mapping to identify alternative blood vessels suitable for future vascular access procedures.

Overall Upper Limb Vascular Health

The examination provides a comprehensive assessment of upper limb circulation, helping doctors optimize dialysis access planning while reducing the risk of complications.

How is AV Fistula Mapping Performed?

AV Fistula Mapping is a safe, painless, and non-invasive examination performed using advanced Color Doppler Ultrasound technology. The procedure usually takes between 30 and 45 minutes and provides real-time assessment of arteries and veins without radiation exposure.

• Your medical history, kidney disease status, and dialysis plan are reviewed before the examination.
• You will lie comfortably while both upper limbs are examined.
• A water-based ultrasound gel is applied over the arms.
• The ultrasound probe is gently moved to evaluate arteries, veins, and blood flow.
• Detailed vessel measurements, Doppler waveforms, and vascular mapping images are recorded.
• A comprehensive mapping report is prepared to assist your nephrologist and vascular surgeon in planning dialysis access surgery.

Benefits of AV Fistula Mapping

AV Fistula Mapping significantly improves the success of dialysis access surgery by providing accurate vascular assessment before the procedure, helping surgeons choose the most suitable blood vessels.

• Improves success rate of AV fistula creation.
• Identifies the best artery and vein for dialysis access.
• Detects vascular abnormalities before surgery.
• Reduces the risk of AV fistula failure.
• Supports better surgical planning and long-term dialysis outcomes.
• Safe, painless, and completely radiation-free examination.
• Provides accurate real-time vascular assessment.
• Helps achieve reliable long-term hemodialysis access.

Preparation Before AV Fistula Mapping

AV Fistula Mapping is a simple, safe, and non-invasive imaging examination that usually requires little or no special preparation. The examination is performed before AV fistula surgery to carefully assess the arteries and veins of the upper limbs. Carrying your previous medical records helps provide a more accurate vascular evaluation.

• Carry your doctor's prescription along with previous Doppler studies, dialysis records, vascular imaging reports, and relevant medical records.
• No fasting is usually required before the examination.
• Wear loose clothing with sleeves that can be easily rolled up for examination of both arms.
• Continue your regular medications unless your treating doctor advises otherwise.
• Arrive at the diagnostic centre 10 to 15 minutes before your scheduled appointment.
• Inform your radiologist about previous dialysis access procedures, vascular surgery, catheter placement, or any history of blood clots.

Is AV Fistula Mapping Safe?

Yes. AV Fistula Mapping is a completely safe, painless, and radiation-free examination that uses high-frequency sound waves to evaluate the arteries and veins before dialysis access surgery. It can be safely performed whenever required and repeated if additional vascular assessment is needed.

At Dr. Dere Sonography & X-Ray Centre, every AV Fistula Mapping examination is performed using advanced Color Doppler technology while maintaining the highest standards of patient comfort, diagnostic accuracy, hygiene, and evidence-based reporting.
