Summary
The TRUST technique offers a safe and effective transradial access (TRA) method for neurointervention, achieving high success rates and low complications. This approach is a promising alternative for complex procedures.
Area of Science:
- Interventional Neurology
- Vascular Surgery
- Medical Devices
Background:
- Transradial access (TRA) is increasingly used for neurointervention but faces challenges like radial artery spasm, leading to conversion to femoral access in 8.6-10.3% of complex cases.
- Lack of adequate catheter support and radial artery spasm are key limitations of TRA in complex neurointerventional procedures.
Purpose of the Study:
- To evaluate the efficacy and safety of the TRUST (trans-radial coaxial catheter technique using a short sheath, Simmons catheter, and Tethys intermediate catheter) technique for neurointerventional procedures via TRA.
Main Methods:
- A single-center retrospective analysis of 16 patients undergoing endovascular interventions using the TRUST technique via TRA between January 2023 and May 2023.
- Procedures included ballooning, stenting, or both, with access via distal or proximal radial arteries.
Main Results:
- The TRUST technique was successfully applied in all 16 patients, with a mean age of 63.8 years (62.5% male).
- The primary indication was intracranial atherosclerotic stenosis (93.75%). Technical success was 100%, with 93.75% achieving mTICI ≥2b recanalization.
- No major access-site complications were reported.
Conclusions:
- The TRUST technique is technically safe and feasible for transradial neurointervention.
- It demonstrates a high technical success rate and a low complication rate, making it a promising alternative for complex neurointerventions.
