title: Successfully treated symptomatic fusiform basilar artery aneurysm in a patient with hindbrain malformation via inverted Y-stenting.
abstract: A double overlapping reverse Y-stent approach to creating flow diversion using traditional open-cell stent technology was evaluated as a treatment option symptomatic fusiform basilar aneurysms. A 36-year-old man with a complex hindbrain malformation presented with acute ocular dysmotility due to a rapidly enlarging fusiform basilar artery aneurysm. The aneurysm was treated by insertion of two stents into the vertebrobasilar system in an inverted Y-configuration from the basilar tip to the V4 segments of the bilateral vertebral arteries, essentially creating flow diversion without using a dedicated flow diversion device. This resulted in immediate symptomatic improvement. The stents remained patent and the aneurysm was obliterated at 6 months follow-up. Furthermore, the patient remained free of associated symptoms at 10 months follow-up. Thus, the double stenting technique can be used instead of a flow diversion device to effectively create flow diversion, promote aneurysm sac thrombosis, and lead to resolution of symptoms in large fusiform basilar artery aneurysms.
