Abstract: Occlusion of a flow diverter construct can complicate the management of vertebrobasilar fusiform aneurysms. A 56-year-old man with nausea, vomiting, headache, dysmetria, and dysdiadochokinesia underwent placement of two flow diverter stents for a fusiform aneurysm extending from the left vertebral artery to the basilar artery. Nine months later, worsening symptoms prompted angiography, which demonstrated left vertebral artery occlusion, narrowing of the proximal stent, aneurysm enlargement, and new thrombus formation. Recanalization was abandoned because of the thrombus burden. A third flow diverter was deployed from the right vertebral artery into the basilar artery through the existing stent struts after sequential balloon dilation, creating a reverse Y configuration. Computed tomography angiography at one month showed satisfactory expansion at the crossing site. Two-month angiography showed decreased aneurysm size, with partial symptom improvement. This case illustrates a technically feasible rescue approach with short-term follow-up.
