Resolution of trigeminal neuralgia by coil embolization of a persistent primitive trigeminal artery aneurysm

The persistent primitive trigeminal artery (PTA) is a rare anastomosis between the carotid artery and basilar artery. While most PTAs are asymptomatic, lateral variants can occasionally compress the trigeminal nerve...

Rupture of Persistent Primitive Trigeminal Artery Aneurysm Associated with a Cavernous Sinus Fistula

We describe a patient with an aneurysm arising at a persistent primitive trigeminal artery ruptured to form a carotid-cavernous fistula. Coil occlusion of the carotid cavernous sinus fistula resulted in flow stasis of the persistent primitive trigeminal artery and resolution of symptoms. A ruptured aneurysm of the persistent primitive trigeminal artery can be associated with a carotid cavernous sinus fistula. Coil occlusion of the cavernous sinus and the PPTA is a safe and effective technique to treat this disease.

Hyperform Remodeling Balloon for the Balloon Occlusion Test of Persistent Primitive Trigeminal Artery Aneurysm-Case Report-

A 17-year-old woman presented with a rare aneurysm at the junction of the persistent primitive trigeminal artery (PPTA) and the internal carotid artery (ICA) manifesting as left abducens nerve paresis. The aneurysm and the ICA were both successfully occluded with coils. The balloon occlusion test used the HyperForm balloon microcatheter to seal the PPTA and ICA, which is very important to determine the optimal treatment strategy for a PPTA aneurysm.
