A dialysis shunt is a medical device used to create access to a patient's bloodstream for dialysis treatment. It is typically made from a synthetic material and is surgically implanted to connect an artery to a vein. This connection allows for efficient blood flow, which is essential for the hemodialysis process, where a machine filters waste and excess fluid from the blood. The shunt is often placed in the arm and can take several weeks to mature before it is ready for use. Proper care and monitoring of the shunt are crucial to prevent complications, such as infection or clotting, ensuring that patients receive effective kidney treatment.
