Summary
A new detachable tip microcatheter enhances safety and control during N-butyl cyanoacrylate (nBCA) embolization for brain vascular malformations. This technique reduces catheter retention risks and improves procedural outcomes.
Area of Science:
- Interventional Neuroradiology
- Neurovascular Interventions
Background:
- Intracranial vascular malformations require embolization using N-butyl cyanoacrylate (nBCA).
- Traditional embolization carries risks of catheter retention.
Observation:
- A novel Apollo 1.5 cm detachable tip microcatheter was evaluated in five patients.
- Nine pedicles were embolized under compassionate use protocols.
Findings:
- Successful detachment of the microcatheter tip occurred in five of nine cases.
- No premature detachments or embolic agent leaks were observed.
- Follow-up confirmed stable, non-migrating detached tips.
Implications:
- Detachable tip microcatheters represent an advancement in nBCA embolization safety and efficacy.
- This technology allows for more controlled and less traumatic catheter retrieval.
- Further studies are warranted to confirm long-term safety and effectiveness.
