Background:
The Neurointerventional Surgery Standards and Guidelines Committee has advocated the use of transradial access in the setting of posterior circulation stroke intervention, however there is a paucity of published data on this approach. The purpose of this study is to present 12-months of prospectively collected data from a high volume thrombectomy center following the adoption of a first line transradial approach for posterior circulation stroke intervention.
Methods:
A range of data on patient characteristics, procedural metrics, complications and outcomes was prospectively collected between August 2018 - August 2019 following the adoption of first line transradial access for posterior circulation stroke intervention at a high volume thrombectomy center.
Results:
Transradial access was successful in 22/23 cases (96%), median arteriotomy to reperfusion time was 24 min (IQR 18-40), good angiographic outcome (mTICI 2b-3) was achieved in all cases and good clinical outcome (mRs 0-2) was achieved in 61% of cases. No intracranial or radial artery access site complications occurred.
Conclusion:
The fast procedure times, excellent outcomes and low complication rates achieved in this prospective 12-month study indicate that transradial access is a viable first line strategy in posterior circulation stroke intervention.
