Summary
Retained intrathecal catheters from lumbar drains can occur during high-risk surgeries. Conservative management is possible for some cases, with periodic follow-up recommended.
Area of Science:
- Neurosurgery
- Anesthesiology
- Neurosurgical Complications
Background:
- Lumbar spinal drains are increasingly used for high-risk surgeries.
- Catheter shearing can lead to retained intrathecal foreign bodies.
- No current guidelines exist for managing retained intrathecal catheters.
Observation:
- Retained catheters often result from insertion or advancement difficulties.
- Approximately one-third of conservatively managed cases develop symptoms.
- Management decisions involve patient factors, fragment characteristics, and risks.
Findings:
- Conservative management is a viable option for select retained intrathecal catheters.
- Surgical removal requires careful consideration of multiple clinical factors.
- Guidelines are needed for prevention and management of this complication.
Implications:
- This review synthesizes literature to propose management guidelines.
- Conservative management with follow-up may prevent unnecessary interventions.
- Standardized approaches can improve patient outcomes and reduce complications.
