Objective And ImportanceWe describe a case of stent-assisted coil embolization of a wide neck right posterior inferior cerebellar artery (PICA) aneurysm via a transbrachial artery approach.Clinical PresentationA 73-year-old woman with a past medical history of hypertension, hyperlipidemia, colon cancer, and osteoporosis presented with a throbbing occipital area headache. Magnetic resonance angiography revealed a wide neck right PICA aneurysm. She presented for a planned endovascular stent-assisted coil embolization.TechniqueThe initial transfemoral approach was complicated by persistent guide catheter instability due to marked tortuosity of the right vertebral artery (VA). The left VA could not be accessed due to left subclavian occlusion with steal syndrome. Neuroform-2 (Boston Scientific; Natick, MA) stent-assisted Matrix (Boston Scientific; Natick, MA) coil embolization was successfully performed through a 6-French guide catheter using a transbrachial approach.ConclusionCurrent advances in technology produce neuroendovascular devices that are smaller with increased flexibility, allowing nonfemoral vascular access to the cerebral circulation via alternate arterial routes. This patient case demonstrates transbrachial access is a viable approach for endovascular aneurysm coil embolization, with or without stent assistance, in cases with an unstable guide catheter due to tortuous vessels or abnormal anatomy when femoral access is complicated or contraindicated.
