An Arteriovenous fistula (AV) fistula is greatly useful as it increases the strength of the vein and facilitates easy access to the blood system. The AV fistula 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 types of access.
An AV fistula requires cautious advance planning as a fistula often takes some time after surgery to develop in certain cases, as long as 24 months.
An AV fistula is created by connecting an artery directly to a vein, quite often in the forearm. This enhances the flow of blood into the vein. In due course, the vein grows larger and stronger. This in turn makes repeated needle insertions for the treatment easier. The surgery is performed using a local anesthetic and can be performed on an outpatient basis.
