A dialysis access, (sometimes called hemodialysis access) is the blood vessel pathway for a machine to remove waste products from the body when the kidneys can no longer cleanse the blood. An interventional radiologist creates an access allowing blood to travel outside the body through soft tubes to the dialysis machine. The cleansed blood is then returned to the circulatory system at the original point of access.

In order to facilate the delivery of the blood from the body and then back again, the radiologist will use diagnostic equipment to visualize the condition of the blood vessels. If the vessels appear strong enough, a connection will be made by joining an artery and vein together. This is done under conscious sedation and usually takes only about an hour. Another interventional procedure that allows for access for dialysis is a graft. This a synthetic material that actually connects an artery with a vein. This procedure allows for the patient to undergo dialysis much quicker than a fistula, but is not as long lasting.

Both of these medical approaches are vital for patients needing dialysis treatment. The specialists at Indiana Radiology Partners are readily available and can provide expert diagnosis and a plan of treatment specific for the patient's well-being and improved health.
