Abstract
Background
Transradial access has been adopted more commonly in the neuroendovascular field. However, the experience of using this access for the Woven EndoBridge embolization of intracranial aneurysms is still in the early stage.
Objective
This study aimed to compare the outcomes between transradial access and transfemoral access for the Woven EndoBridge embolization of intracranial aneurysms.
Methods
This is a retrospective analysis of consecutive intracranial aneurysms treated with Woven EndoBridge placement between May 2019 and August 2020 by the senior author at a high-volume center. The aneurysms of all sizes and locations treated with Woven EndoBridge placement with or without adjunctive stent or coiling were included. Patient demographics, aneurysm and treatment characteristics, procedural complications, and angiographic and functional outcomes were compared between two approaches.
Results
This study included a total of 34 patients with intracranial aneurysms (median age 60 years, female-to-male ratio 2:1). Of these, the radial access was utilized in 20 (58.8%) patients, while the femoral access was used in 14 (41.2%) patients. A Woven EndoBridge device was successfully deployed in all cases, and none of the patients required a crossover to another access. There were no significant differences in baseline characteristics, procedure time and fluoroscopy time, outcomes, and complication rates between both groups.
Conclusion
Our report suggests the possible feasibility and safety of the transradial access for the Woven EndoBridge embolization of intracranial aneurysms. However, the results of this study are suggestive rather than conclusive, and there is still a need for future large prospective studies.
