If you are suffering from chronic renal failure, we can help you with minimally invasive treatment. Particularly through our expertise in endovascular creating and maintaining arteriovenous (AV) fistulas, as well as placing tunneled hemodialysis and peritoneal dialysis catheters. In the case of AV fistulas, we are skilled in both the endovascular creation and maintenance of these critical access points for dialysis, ensuring optimal blood flow and minimizing complications. We also perform interventions to address issues like stenosis or thrombosis, which can compromise fistula function.
Additionally, interventional radiologists are integral in the placement of tunneled hemodialysis catheters, ensuring proper positioning for effective dialysis treatment. For patients requiring peritoneal dialysis, interventional radiology is crucial in placing peritoneal dialysis catheters, facilitating safe and efficient dialysis. These procedures, performed under image guidance, significantly improve patient outcomes, reduce the need for surgical interventions, and enhance overall dialysis management.
There are two main types of dialysis used to treat kidney failure:
Hemodialysis (HD): This method involves using a machine and a dialyzer (artificial kidney) to filter waste and excess fluid from the blood. Blood is drawn from the body, cleaned by the machine, and returned to the body. Hemodialysis is typically performed at a dialysis center, usually three times a week.
Peritoneal Dialysis (PD): This type uses the lining of the abdomen (the peritoneum) as a natural filter. Dialysis fluid is introduced into the abdominal cavity through a catheter, where waste and excess fluids are removed from the blood vessels in the peritoneum. It can be done at home, either manually or automatically at night with a machine.
We can help by placing Tunneled Hemodialysis (HD) Catheter and Tunneled Peritoneal Dialysis (PD) Catheter.
Tunneled HD Catheter: This catheter is inserted through a small incision, usually in the neck or chest, and guided into a large vein near the heart for hemodialysis. The catheter is tunneled under the skin to prevent infection and ensure secure placement. The procedure is typically done under local anesthesia with imaging guidance (like ultrasound or fluoroscopy) to ensure proper placement.
Tunneled PD Catheter: For peritoneal dialysis, a catheter is placed into the abdominal cavity through a small incision. The catheter is tunneled under the skin, and its tip is positioned in the peritoneal space for dialysis fluid exchange. Imaging is used to guide placement, and local anesthesia is administered during the procedure.
Both procedures are minimally invasive, with a short recovery time and reduced risk compared to traditional surgery.
Additionally, we can help maintain your dialysis AV (arteriovenous) fistula by performing procedures to address issues such as blockages, narrowing, or thrombosis (blood clots). IR techniques, like angioplasty (inflating a balloon to open narrowed areas) or thrombectomy (removal of clots), can restore proper blood flow to the fistula, ensuring it functions effectively for dialysis. These procedures are minimally invasive, with a quick recovery time and less risk compared to traditional surgery, helping to prolong the life of the AV fistula and improve dialysis access.
