Starting Dialysis: Inserting and Maintaining Your Vascular Access

Before starting dialysis, a vascular access is needed; this is a site on your body from which your blood is removed and returned. 

Same-day Consultation, Ultrasound and Placement

When you are referred to the Dialysis Access Center, you will have a consultation, a vein mapping ultrasound, and the placement of your new access for dialysis. Because we have a dedicated facility and full-time clinical team devoted to dialysis access, we are usually able to accomplish all of this in the same day. The process takes about 4 to 5 hours.

Once your new access is placed, it takes time to mature and heal before it is usable for dialysis. We will give you more information specific to your condition and will see you several weeks after your procedure to ensure things are healing properly. 

Preventative Visits Can Prevent Problems with Your Vascular Access

After you start receiving dialysis through your new access, we will follow up with you and your dialysis center regularly to ensure that your access stays healthy and usable. It is not unusual that an acute or urgent problem develops with your access; for example, an infection, clot, blockage, or excessive bleeding. Rest assured that we are ready to take care of these problems as well – usually on the same or next business day.

Remember: regular preventive visits to the DAC are important to maintain your access and reduce the likelihood of any urgent problems.

Vascular Access for Hemodialysis

Hemodialysis is most commonly used to treat advanced and permanent kidney failure. In hemodialysis, your blood flows a few ounces at a time through a special filter that removes wastes and extra fluids. The clean blood is then returned to your body.

Catholic Health can insert and maintain your vascular access for hemodialysis. We offer:

  • Evaluation for the insertion of a vascular access
  • Catheter insertion/exchanges
  • Catheter removals
  • Venography - an x-ray test used to determine placement of central venous catheters or hemodialysis fistulas
  • Doppler - evaluates how well the fistula is functioning
  • HeRO shunt insertion for patients who have exausted hemodialysis access sites
  • Minimally invasive shunt placements for patients who have no appropriate vessels for fistula creation
  • Creation of arteriovenous fistulae (using your own veins for hemodialysis)
  • Insertion of arteriovenous shunts (insertion of a plastic tube under the skin for hemodialysis in patients with vein problems)

Vascular Access for Peritoneal Dialysis

With peritoneal dialysis (PD), a soft tube called a catheter is used to fill your abdomen with dialysis solution, a cleansing liquid. Waste products and extra fluid pass from your blood into the dialysis solution that will pull wastes and extra fluid into the abdominal cavity. These wastes and fluid then leave your body when the dialysis solution is drained.

Our center can insert and maintain your vascular access for peritoneal dialysis. We offer:

  • Catheter insertion/exchanges
  • Catheter removals
  • Revisions and repairs of nonfunctioning catheters

Maintaining Blood Flow

Blood clots or blockages may interfere with your dialysis. When fistulas and grafts become clogged or narrowed, they can prevent you from undergoing dialysis.

To maintain blood flow through your vascular access, we offer:

  • Fistulagarms / Shuntograms - an x-ray test to look inside your dialysis access, whether it is a fistula or shunt. This x-ray test detects imperfections or narrowing in the access or the blood vessels leaving the access. It checks for blood clots or other blockages.
  • Ultrasound - evaluates for blockages or areas of narrowing in the graft/fistula
  • Graft declotting (thrombectomy) - minimally invasive procedure performed to improve blood flow in the fistula and grafts placed in the blood vessel
  • Angioplasty - uses mechanical devices, such as a balloon, to open fistulas and grafts and helps them remain open
