Tunnelled Catheter ( perma catheter)

Dr. Kiran’s Renal Center provides comprehensive renal care for patients with chronic kidney disease (CKD) and those who require dialysis. One of the most essential elements of dialysis treatment is ensuring a secure, long-term vascular access method. Tunnelled dialysis catheters are one such solution, offering both safety and convenience for patients who need reliable and consistent dialysis access over a long period.

What is a Tunnelled Dialysis Catheter?

A tunnelled dialysis catheter is a medical device specifically designed to provide a direct pathway to the bloodstream, allowing blood to flow in and out during dialysis treatments. Unlike temporary catheters that are inserted through the skin directly into a vein, tunnelled catheters are surgically placed under the skin and are tunneled to reach a vein. This approach minimizes risks and provides a more durable solution for patients who require long-term dialysis.

These catheters are typically used when other access points like arteriovenous fistulas or grafts are not suitable or have failed. It is important to note that tunnelled dialysis catheters are generally intended for medium- to long-term dialysis use, making them ideal for patients who are not candidates for more permanent dialysis access.

Key Benefits of Tunnelled Dialysis Catheters

• Durability for Long-Term Use:Tunnelled catheters are designed to remain in place for extended periods (typically several months to a year or longer), providing a long-term access solution for patients in need of ongoing dialysis.
• Comfort and Reduced Risk of Infection:Since the catheter is tunneled under the skin, it is less exposed to external elements, which helps minimize the risk of infections. Additionally, the positioning of the catheter under the skin ensures better comfort and mobility for patients compared to external temporary catheters.
• Minimally Invasive Procedure:The placement of a tunnelled catheter is a relatively simple and minimally invasive procedure, requiring only local anesthesia and mild sedation. This contrasts with more invasive surgeries that may be needed to create permanent access points like fistulas.
• Preserves Other Access Sites:By using a tunnelled catheter, other potential access sites like arteriovenous (AV) fistulas or grafts can be preserved for future use, offering more flexibility in long-term dialysis management.
• Reliable Dialysis Access:With proper care, tunnelled catheters can provide consistent and reliable dialysis access, which is critical for maintaining optimal treatment schedules and overall health.

When is a Tunnelled Dialysis Catheter Recommended?

Tunnelled dialysis catheters are typically recommended when other dialysis access options, like an arteriovenous (AV) fistula, are not viable due to vein conditions, or when a patient needs urgent dialysis and a temporary catheter would not be suitable. They are commonly used in the following situations:

• Patients with limited vascular access options
• Patients awaiting AV fistula maturation
• Those needing dialysis immediately or in the short-term
• eople who have had unsuccessful attempts at other access types
