Navien catheter experience in neuroendovascular interventions

PurposeAdvancements in catheter technology have allowed for greater flexibility and trackability. We report 265 consecutive, single-center neurointerventional cases using the Navien guide catheter.Materials and methodsRetrospective analysis was performed of consecutive intracranial endovascular procedures utilizing the Navien catheter. Data collected included procedure type, catheters, guide catheter position, cervical access artery tortuosity grade and complications.ResultsThe 5 French catheter was used in 130 cases. The 6 French catheter was used in 135 cases. Access was via the internal carotid artery in 204, external carotid artery in 10, and vertebral artery in 51 cases. Catheter tip position was in the petrous segment of the internal carotid artery in 36.6% (97/265), distal cervical internal carotid artery in 13.9% (37/265), cavernous internal carotid artery in 10.2% (27/265), proximal or mid cervical internal carotid artery in 5.6% (15/265), supraclinoid internal carotid artery in 0.8% (2/265), and...
