Insights
Recurrent migration of central venous catheters used for haemodialysis can be reduced. A paramedian tunnel placement for internal jugular vein catheters may prevent catheter tip migration in patients with obesity or large breasts.
Area of Science:
- Vascular Surgery
- Nephrology
- Medical Devices
Background:
- Tunnelled, cuffed central venous catheters are essential for haemodialysis.
- Internal jugular vein catheters are typically tunnelled subcutaneously to the anterolateral chest wall.
- Lateral subcutaneous tracts increase catheter migration risk, especially in obese patients or those with large breasts, leading to catheter failure.
Purpose of the Study:
- To describe a novel surgical technique for central venous catheter placement.
- To address recurrent catheter migration in patients undergoing haemodialysis.
Main Methods:
- Two cases of internal jugular vein catheter placement are presented.
- A paramedian subcutaneous tunnel was fashioned instead of the traditional lateral tunnel.
- The technique aimed to mitigate risks associated with obesity or large breast tissue.
Main Results:
- The paramedian tunnel technique was successfully implemented in both cases.
- Recurrent catheter migration was prevented post-operatively.
- This approach offers a viable alternative for managing challenging catheter placements.
Conclusions:
- A paramedian tunnel for internal jugular vein haemodialysis catheters is a promising modification.
- This technique may reduce catheter migration in patients with specific anatomical challenges.
- Further studies are warranted to evaluate the long-term efficacy and broader applicability of this method.
Abstract:
Tunnelled, cuffed central venous catheters are commonly used for the provision of haemodialysis. Internal jugular vein catheters are generally tunnelled subcutaneously to the anterolateral chest wall. However, the lateral subcutaneous tract may increase the risk of catheter migration, particularly in the setting of obesity or large breast tissue. Catheter tip migration is an important cause of catheter failure. We describe two cases in which a paramedian tunnel was fashioned in patients experiencing recurrent catheter migration.
