What Is It?
Dialysis is a process used to treat patients whose kidneys are not working properly. It involves a special machine and tubing that removes blood from the body, cleanses it of waste and extra fluid and then returns it back to the body. In order for a person to undergo dialysis, a physician first creates access to your blood vessel. Short term dialysis access involves placing a catheter into the chest and into a large vein. Long term dialysis access involves joining an artery to a vein and lies completely beneath your skin and is usually in your arm, but sometimes in the leg, and allows blood to be removed and returned quickly, efficiently, and safely during dialysis.
How is the Procedure Performed?
Using image guidance, a dialysis catheter is placed in the upper chest area, usually about an inch under the collar bone. The end of the catheter is threaded into a large vein in the chest.
If fistulas or grafts become clogged or narrowed, dialysis is not successful. Our radiologists use imaging to guide a catheter (a long, thin plastic tube) in to an artery or vein and advance it to the problem area—the narrowing or blockage that is limiting blood flow. From there, a balloon or stent can be used to fix the problematic area. Other times, clots can be removed to unclog the vessels.
How Do I Prep For The Procedure?
Do not eat or drink anything after midnight (12:00 am) the night before your procedure. You may take medications with a sip of water in the morning. Bring a list of all prescribed medications with you to the procedure. You may be asked to hold diabetic/weight loss medication or blood thinners. You should arrange to have someone take you home after the procedure.
What Happens After The Procedure?
After the procedure, the insertion site is monitored for any signs of complications such as bleeding or infection. Patients go home the same day. Successful dialysis access management enhances the efficiency of the vascular access, allowing for better removal and return of blood during hemodialysis sessions. Patients typically notice increased comfort during dialysis and a reduced risk of complications related to inadequate blood flow. Regular monitoring and management of dialysis access contribute to the overall effectiveness and longevity of the vascular access for individuals undergoing hemodialysis treatment.
