Persistent primitive trigeminal artery is a rare anatomical variant resulting from the absence of obliteration of the embryonic trigeminal artery. The shunt between the persistent primitive trigeminal artery and the cavernous sinus is called trigeminal-cavernous fistula. We report the case of a woman with a trigeminal-cavernous fistula secondary to head trauma who was treated by transarterial embolization.

Purpose And Background: The trigeminal artery is a rare anatomical variant, representing an embryonic vestige of the anastomosis between the internal carotid artery and the posterior circulator system, that can be asymptomatic or could have vast clinical manifestations produced by insufficient flow or by vascular nervous conflicts. This study is an anatomical presentation of 3 trigeminal artery cases observed at Medimar Imagistic Services Constanta.
Methods: The 3 trigeminal artery cases were discovered on a 860 magnetic resonance angiographies (0.

Purpose: A persistent trigeminal artery is the most common persistent carotid-vertebrobasilar anastomosis. Persistent trigeminal artery variants (PTAVs) terminate in the cerebellar arteries without connecting to the basilar artery; of these, the anterior inferior cerebellar artery (AICA) is the most common. AICA duplication is frequently observed.

Purpose: To describe a case in which a right replaced posterior cerebral artery (PCA) was associated with an ipsilateral superior cerebellar artery (SCA) type persistent trigeminal artery (PTA) variant.
Methods: A 53-year-old man who had been diagnosed with chronic dissection of the left vertebral artery (VA) 4 months previously underwent follow-up magnetic resonance (MR) angiography using a 3-Tesla scanner.
Results: MR angiography showed a slightly dilated left VA at the terminal segment without interval change.

Background: Full-endoscopic microvascular decompression (fE-MVD) is an emerging treatment option for trigeminal neuralgia (TN). However, the risk factors associated with postoperative recurrence of TN after fE-MVD procedure remain controversial. The aim of the present study was to summarize the surgical technique of fE-MVD for the treatment of TN and to develop a predictive model for recurrence at 1 year postoperatively based on independent risk factors.

Objective: Multiple techniques have been used to treat trigeminal neuralgia (TGN), including pharmacotherapy, radiosurgery, rhizotomy and microvascular decompression (MVD). Blood vessels are considered to be the most common cause of offense and compression to trigeminal nerve. We aimed to determine the causes of classic TGN and efficacy of MVD.
