Transradial access (TRA) is a safe and effective alternative to transfemoral access (TFA) for cerebral angiography. This study shows TRA preserves safety and efficiency during the transition, supporting its wider use in neurointerventional procedures.
Area of Science:
- Neurointerventional radiology
- Vascular access techniques
Background:
- Transradial access (TRA) adoption for neurointerventional procedures lags despite evidence.
- Initial institutional success with TRA for stroke thrombectomy prompted broader use in cerebral angiography.
Purpose of the Study:
- To evaluate the safety and efficacy of transitioning from transfemoral access (TFA) to transradial access (TRA) for cerebral angiography.
- To analyze patient selection, technical aspects, complications, and the operator learning curve during this transition.
Main Methods:
- Retrospective review of 148 cerebral angiograms performed via TRA between January 2016 and February 2017.
- Analysis included patient selection criteria, technical details, patient outcomes, and operator proficiency over time.
Main Results:
- No major complications were reported in 148 TRA procedures.
- Technical success rates were comparable to TFA.
- Operator efficiency improved significantly within a limited number of cases (4.3 vs 3.6 min/vessel).
Conclusions:
- Transitioning to TRA for cerebral angiography can maintain procedural safety and efficiency.
- Findings suggest a re-evaluation of TRA's role in cerebral angiography is warranted.
- Further research is needed to support widespread TRA adoption.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
