Dialysis Catheter Placement

Dr. Ilya Khantalin in Nice

The placement of a catheter for hemodialysis is a crucial procedure for patients requiring blood purification due to renal failure. This intervention facilitates access to the bloodstream to perform dialysis, a treatment that temporarily or permanently replaces the function of failing kidneys. Ensuring the quality and safety of this procedure is essential to avoid complications and provide optimal care for dialysis patients.

Endovascular techniques are currently the most modern and commonly used approaches by vascular surgeons, in compliance with guidelines from the Haute Autorité de Santé and integrated into standardized surgical protocols.

Vascular diseases are recognized as Long-Term Illnesses (Affections de Longue Durée – ALD), enabling 100% coverage by French Social Security.

What is a Dialysis Catheter?

Vascular Surgeon in Saint-Laurent-du-Var

A tunneled hemodialysis catheter is a thin, flexible tube generally inserted into a large vein, often located in the neck (jugular vein), chest (subclavian vein), or groin (femoral vein). This temporary or semi-permanent device allows healthcare professionals, particularly nephrologists, to access the bloodstream easily for dialysis without requiring multiple punctures or invasive procedures at each session.

Catheters are primarily used for patients who do not yet have an arteriovenous fistula or vascular graft for dialysis, which are more durable access options but require time to mature and become functional. The catheter thus enables the initiation of dialysis without delay, which is critical in cases of acute renal failure or urgent care.

Indications and Procedure for Dialysis Catheter Placement

Catheter placement is indicated in several clinical situations, including:

  • Acute renal failure: Patients with rapidly deteriorating kidney function require immediate catheter placement to begin dialysis without delay.
  • Chronic renal failure awaiting fistula maturation: Patients often need a temporary catheter while waiting for their arteriovenous fistula to mature, which may take several weeks.
  • Patients unsuitable for fistula or graft: Anatomical or vascular conditions may preclude permanent vascular access options; in such cases, a dialysis catheter is the main access route.
  • Temporary dialysis needs: Dialysis may be required temporarily in cases of poisoning, severe fluid overload, or life-threatening electrolyte imbalances.

Dialysis catheters vary based on their intended duration and insertion site, with tunneled catheters providing semi-permanent access and non-tunneled catheters used for short-term dialysis.

Catheter placement is typically performed under local anesthesia, following strict aseptic conditions to minimize infection risk. The vascular surgeon identifies the target vein, inserts the catheter using a guidewire, and confirms its position via ultrasound or X-ray. The procedure is quick, allowing gradual resumption of normal activities.

Meticulous follow-up is essential to prevent complications and maintain catheter function. Key aspects include:

  • Care of the insertion site: Regular cleaning and sterile dressing of the catheter area.
  • Infection prevention: Strict hygiene protocols to reduce risks of venous infections and sepsis; unnecessary catheter manipulation should be avoided.
  • Patency control: Anticoagulant solutions may be injected to prevent clot formation and catheter obstruction.
  • Monitoring for complications: Redness, pain, abnormal discharge, or fever warrant immediate medical consultation to prevent serious complications.

Advantages:

  • Immediate access to the bloodstream allows prompt initiation of dialysis without waiting for fistula maturation.
  • Less invasive compared to creating fistulas or grafts, often resulting in less discomfort.

Disadvantages:

  • Higher infection risk, especially with prolonged use.
  • Limited lifespan compared to fistulas, not designed for permanent access.

 

Vascular access requires expertise in vascular anatomy and surgical technique to minimize risks and ensure quality dialysis access.

Catheter placement for dialysis is a critical step in managing patients with acute or chronic renal failure. This device provides rapid and effective access to the bloodstream, but requires careful follow-up to prevent infection and maintain functionality. Whether for temporary dialysis or in the absence of other vascular access options, catheter placement must be performed by an experienced vascular surgeon.

As a vascular surgeon in Saint-Laurent-du-Var, Dr. Ilya Khantalin supports you throughout the catheter placement and follow-up process for tunneled hemodialysis catheters.
