Transradial access for embolization of cerebral aneurysms with the woven EndoBridge device: Case series and review of the literature.

Abstract

Transradial access is an increasingly utilized route for neurointerventions with benefits of lower rates of access site complications, earlier patient mobilization and increased patient satisfaction over transfemoral interventions. There is limited data on deployment of the Woven EndoBridge (WEB) via transradial access. We report a case series of consecutive patients undergoing cerebral aneurysm embolization with the WEB device via transradial biaxial access. A database of neuroendovascular procedures was queried for consecutive aneurysm embolization procedures involving the WEB device and intended via the transradial approach between August 2019 and July 2020. Patient demographics, radiological aneurysm characteristics and procedure details were recorded and statistically evaluated. Google Scholar and Pubmed were searched for previous reports of transradial WEB embolization. Ten aneurysms were treated in ten patients. All aneurysms were treated with successful WEB deployment. Nine of the ten aneurysms were successfully treated via transradial biaxial access. One aneurysm required conversion to transfemoral access. There were no clinical complications and no morbidity or mortality. Transradial embolization of cerebral aneurysms with the WEB device is safe and feasible with low rates of access failure or complications.
