Arteriovenous (AV) fistula in the making!

This is a connection, made by a vascular surgeon, of an artery to a vein, with the main goal of having a regular vascular access for life-saving hemodialysis treatments. An AV fistula is usually made in the forearm or upper arm. It essentially causes extra pressure and extra blood to flow into the vein, making it grow large and strong. The larger vein provides easy, reliable access to blood vessels. Without this kind of access, regular hemodialysis sessions would not be possible. Photo credit : @tariqrahim
