Summary
Transradial cerebral angiography is a safe and effective technique for neuroangiography. This method allows access to all relevant vessels for diagnostic and interventional procedures.
Area of Science:
- Neurology
- Interventional Radiology
Background:
- The transradial approach is common for coronary angiography, but data on its use in cerebral angiography are limited.
- This report details procedural methods for transradial cerebral angiography to encourage wider adoption.
Purpose of the Study:
- To provide detailed procedural methods for transradial cerebral angiography.
- To facilitate the adoption of the transradial approach for cerebral angiography.
Main Methods:
- A review of 60 consecutive transradial neuroangiography cases.
- Cataloging indications, sheath size, catheter type, procedure length, access success rates, and complications.
- Noting details on adjunctive medications, preprocedural assessment, and postprocedural care.
Main Results:
- Successful transradial angiography in 57 of 60 cases (51 diagnostic, 6 interventional).
- Sheath sizes ranged from 4F to 6F; mean procedural time was 40 minutes for diagnostic cases.
- One access-site complication (forearm hematoma) was reported.
Conclusions:
- Transradial angiography is a valuable tool for neuroangiographic procedures.
- The radial artery provides access to all necessary vessels for diagnostic cerebral angiography.
- Interventions in the right vertebral and carotid systems are facilitated by this approach.
