Abstract
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.
