Dialysis access

A dialysis access is a site on a person's body created so that blood or other fluids can be removed, filtered, and returned to the body during dialysis. Dialysis is a process that performs the work of healthy kidneys for people who have kidney failure.

Before dialysis can begin, the doctor has to create a dialysis access. For hemodialysis, the access is the place where the dialysis needles are inserted to send the blood to and from the dialysis machine. In peritoneal dialysis, the access is the place where a catheter is connected so fluid can flow into and out of the belly.

Depending on the type of dialysis, the doctor may:

  • Attach an artery to a vein, usually in the lower arm. This is called a fistula. After the fistula is healed, the dialysis needles can be put directly into it. Fistulas tend to be stronger and less prone to infection than grafts.
  • Implant a tube (graft) under the skin of an arm or leg that connects an artery and a vein. The dialysis needles can then be put into the graft for hemodialysis. A graft is a good choice if the person has small veins or other problems.
  • Place a tube (catheter) in the belly for peritoneal dialysis.

Usually, the doctor has to prepare the dialysis access weeks to months before it is needed. This gives the access time to heal. If a person needs emergency dialysis, the doctor may create a temporary access by inserting a catheter into a vein in the neck, upper chest, or groin.

Due to the threat of the COVID-19 (Coronavirus), we are taking precautionary measures to protect our staff and patients. We are implementing a temporary NO VISITOR policy at this time. Only patients or patients and their guardians will be allowed into the office. Please note, this is not to inconvenience anyone! The virus is a very real threat and it is essential that we stay healthy in order to provide needed care for our patients. If you are sick, we ask that you CALL the office to speak with a nurse before you come in. The nurse will provide specific instructions for you. Please DO NOT enter the office if you are sick (upper respiratory symptoms, fever, cough, or flu like symptoms). We are closely monitoring the situation and will update you as circumstances change. Thank you for your understanding!!
