What is a DOPPLER ASSESSMENT OF AV FISTULA(UPPER LIMB)?

Doppler Assessment of AV Fistula (Upper Limb) is a non-invasive ultrasound examination that evaluates the blood flow and function of an arteriovenous (AV) fistula used for hemodialysis. It helps detect narrowing, thrombosis, reduced blood flow, aneurysms, and other vascular complications affecting dialysis access.

FAQs

What is a Doppler Assessment of AV Fistula (Upper Limb)?

Doppler Assessment of AV Fistula (Upper Limb) is a non-invasive ultrasound examination that evaluates the blood flow and function of an arteriovenous (AV) fistula created in the arm for hemodialysis.

Why is this examination performed?

The examination is performed to ensure that the AV fistula is functioning properly and to detect complications such as narrowing (stenosis), blood clots (thrombosis), reduced blood flow, aneurysms, or other vascular problems.

What is an AV fistula?

An arteriovenous (AV) fistula is a surgically created connection between an artery and a vein, usually in the arm, that provides reliable vascular access for patients receiving hemodialysis.

Can this examination determine whether my AV fistula is ready for dialysis?

Yes. Doppler ultrasound helps assess whether the fistula has matured adequately, has sufficient blood flow, and is suitable for regular dialysis use.

Can Doppler ultrasound detect narrowing of the AV fistula?

Yes. It can accurately identify stenosis (narrowing), which is one of the most common causes of poor dialysis access and reduced blood flow.

Can this examination detect blood clots?

Yes. Doppler ultrasound is highly effective in detecting thrombosis (blood clots) within the AV fistula or nearby blood vessels.
