When a fistula forms between an artery and a vein within the dura, it is called Brain Dural Fistula, or Brain Dural Arteriovenous Fistula, or BDAVF, etc When a fistula forms, blood from an artery under high pressure and flow goes directly into a vein, which is a low pressure and low flow structure Even though the fistula is not directly on orA fistula (also called an arteriovenous fistula or AV fistula) is made by joining an artery and a vein under the skin in your arm When the artery and vein are joined, the pressure inside the vein increases, making the walls of the vein stronger The stronger vein can then receive the needles used for hemodialysisUltrasound a fistula may be visualized directly, with an abnormal highvelocity connection between the artery and vein even if the fistula cannot be visualized directly, changes in the artery upstream from the fistula and the vein increased diastolic arterial flow due to its connection to the
