Silastic catheter separation during dialysis is a rare but serious complication. Prompt recognition and intervention, like dividing sutures, can prevent catheter transection in patients with renal failure.

Area of Science:

  • Nephrology
  • Vascular Surgery
  • Medical Device Complications

Background:

  • Large-bore, double-lumen Silastic catheters enable immediate dialysis for renal failure patients awaiting arteriovenous fistula maturation.
  • Catheter-related infections and thrombosis are common, but catheter separation is infrequently reported.

Observation:

  • Two cases of Silastic catheter separation are presented.
  • One catheter was sheared by a subcutaneous suture.
  • In the second case, early detection allowed for suture division and catheter retrieval before transection.

Findings:

  • Catheter separation, though rare, can occur due to mechanical complications like suture entanglement.
  • Vigilance and direct visualization at the venotomy site are crucial for managing potential snaring.

Implications:

  • Awareness of catheter separation risk is vital for clinicians managing dialysis access.
  • Suture management during catheter insertion and removal requires careful attention to prevent device damage.
