O21 Safety of intracranial aneurysm treatment by robotically assisted flow diverter implantation

Le résumé fourni par la source

Introduction Intraprocedural intracranial aneurysm rupture is one of the most critical possible complications during endovascular treatment. Aim of Study The aim of this study was to evaluate the risk of intracranial aneurysm rupture during robotically assisted flow diverter implantation, using the CorPath GRX robotic system. Methods From February 1, 2022 to March 20, 2024, 65 target aneurysms (45 saccular) were treated by robotically assisted flow diverter implantation. The most common location of the target aneurysm was ICA (33), followed by AComA (17), MCA (8), ACA (1), AChoA (1), basilar artery (2), PCA (2), and VA (1). Results Only one (1.5%) intraprocedural aneurysm rupture was recorded, without the need for manual conversion. Aneurysm rupture was detected on angiogram after microcatheter navigation through aneurysm sac, before flow diverter implantation. No signs of continuous extravasation were visible after the implantation of the flow diverter. The patient recovered completely. Conclusion The risk of intraprocedural intracranial aneurysm rupture during robotically assisted flow diverter implantation is low. The results of this study confirmed an acceptable risk of robotically assisted procedures.
