    Abstract:
    Endovascular treatment of recurrent basilar aneurysms is challenging due to significant changes in the configuration of the aneurysm and adjacent vessels from prior interventions.1 Coil compaction is a common cause of recurrence and alters the aneurysm morphology significantly.2-4 Stenting of the basilar artery into a posterior cerebral artery modifies the angles between these vessels.5 In this video, we discuss a combined approach via the anterior and posterior circulation for stent-assisted coiling of a recurrent basilar tip aneurysm (Video 1) . A patient in their 40s with a history of ruptured aneurysm underwent multiple endovascular interventions including coiling, stent-assisted coiling, and Woven Endobridge (WEB) device. The patient presented with worsening headaches and underwent treatment with stent-assisted coiling for recurrence. After encountering challenges with direct access from the basilar artery, a combined anterior and posterior circulation approach was used.6 The stent was deployed through the posterior communicating artery and a snare was used to navigate the complex anatomy. neurintsurg;15/5/512/V1F1V1Video 1 .
