WebHow does an AV shunt work? A fistula (also called an arteriovenous fistula or A-V 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 hemodialysis. WebA shunt usually consists of two catheters and a one-way valve. The valve regulates the amount, flow direction, and pressure of cerebrospinal fluid out of the brain’s ventricles. As the pressure of cerebrospinal fluid inside the brain increases, the one-way valve opens and the excessive fluid drains to the downstream cavity. flytomoonWebOct 11, 2024 · VP shunting is a surgical procedure that primarily treats a condition called hydrocephalus.
