Abstract
Vertebrobasilar junction and basilar trunk aneurysms are extremely difficult to treat, with significant morbidity associated with bypass-trapping procedures. As a result, endovascular techniques including flow diversion and stent-assisted coil embolization have become the mainstay of treatment.1-3 Traditional flow diverters pose risk of occlusion of basilar perforator arteries while traditional stents used as adjuncts for coil-embolization often have high porosity and cannot function as flow diverters. On the other hand, the LVIS stent uniquely provides more porosity than other flow diverters,4,5 allowing patency of perforators while also being amenable to stent-assisted coiling. We present a case of a mixed saccular and fusiform basilar trunk aneurysm that underwent LVIS stent-assisted coil embolization. Using bifemoral access with triaxial systems, one microcatheter was placed in the aneurysm sac and another was used to deploy a stent from the basilar apex into the right vertebral artery. A durable angiographic outcome was observed at 9 months.
