Implanted intrathecal pump catheter migration rates in the management of cancer-related pain
Authors' conclusion
Minor catheter migration is relatively common following ITP implantation, but clinically significant migration is rare with the anchoring and closure techniques described.
Study context

- Outcome
- Catheter migration (movement by ≥1 vertebral level between two chest CT scans ≥30 days apart)
