Early experience using optical coherence tomography for intraluminal evaluation of vascular healing associated with endovascular treatment of intracranial aneurysms

Intravascular OCT was a feasible method to visualize the vascular remodeling process during treatment of intracranial aneurysms. It also provides a valuable decision-making tool by clearly highlighting potential complications, such as malapposition, intrastent thrombosis, or excessive endothelialization leading to stenosis. This study represents the second reported series using intravascular OCT in patients with intracranial aneurysms, and it includes the largest cohort to date. Further studies are needed to validate the utility of OCT in the neurovascular field, and development of dedicated OCT devices for intracranial navigation is essential.
