Conventional Arteriovenous Fistula (AV) Fistula

An Arteriovenous fistula (AV) fistula is greatly useful as it increases the strength of the vein and facilitates easy access to the blood system. It is regarded as the best long-term vascular access for Hemodialysis as it ensures sufficient blood flow, lasts for a longer period of time, and has fewer complications than other access types.

An AV fistula requires cautious advance planning as a fistula often takes some time after surgery to develop in certain cases, usually 4-6 weeks. It is created by connecting an artery directly to a vein, quite often in the forearm, to enhance the flow of blood into the vein. In due course, the vein grows larger and thicker, which in turn makes repeated needle insertions for the treatment easier. The surgery is performed using a local anaesthetic.

Once referred by your nephrologist for creation of AV fistula, you will be thoroughly assessed by our expert team and then a suitable site for fistula creation will be decided basis clinical findings and Doppler reports.

Arteriovenous Graft

If there are small veins that won’t develop into a fistula, a vascular access that connects an artery to a vein is created with the help of a graft or a synthetic tube, implanted under the skin in your arm. This graft acts as an artificial vein that can be repeatedly used for the placement of needle and blood access during the process of Hemodialysis. A graft could be used soon after placement.
