Y-configuration stent deployment strategies for aneurysms with complex configurationare well recognized, with and without subsequent coil placement. Delivery of flow diverters in this configuration has no precedent in the literature and may be a viable alternative when feasible. A case is presented in which this configuration for a complex anterior cerebral artery aneurysm was achieved, with subsequent successful aneurysm closure.

A 74-year-old male developed cervical carotid artery psuedoaneurysm 8 months after carotid endarterectomy. The patient was successfully managed with dual implantation of flow-diverter and conventional carotid stent. Flow-diverter was placed across the neck of pseudoaneurysm to provide flow diversion while carotid stent was implanted within the lumen of the expanded flow-diverter to approximate and hold the flow diverter proximal and distal to the pseudoaneurysm. Follow-up ultrasonography revealed complete resolution of the pseudoaneurysm.

Aneurysms of the persistent trigeminal artery (PTA) trunk are exceptionally rare and have a high risk for rupture. Dual stent placement through each internal carotid and basilar artery for endovascular coil embolization of a fusiform aneurysm arising from the PTA has not been described in the literature. A 44-year-old female with a history of chronic headache was identified to have a fusiform aneurysm arising from medially coursing adult type, Saltzman type 3 PTA trunk. Sacrifice of the PTA trunk inclusive of the aneurysm was performed with dual stent placement through each basilar and internal carotid artery across their respective junctions with the PTA. Six-month follow-up angiography showed complete occlusion of the PTA and the aneurysm. The patient's symptoms resolved. Our case demonstrated that the sacrifice of an adult type, Saltzman type 3 PTA inclusive of an associated fusiform aneurysm is feasible with dual stent-assisted coil embolization.
