Anatomical features and clinical relevance of a persistent trigeminal artery

Aneurysm of a persistent trigeminal artery.

Persistent primitive trigeminal artery: a review.

The trigeminal artery is the largest of the fetal carotid-basilar anastomotic arteries, and it persists for the longest embryonic period. The artery usually involutes after the development of the posterior communicating artery. The exact causes of persistence of this primitive vessel into adulthood are not completely clear. Angiographic and anatomical descriptions of the various persistent trig...

Trigeminal Neuralgia Caused by Persistent Primitive Trigeminal Artery

A 66-year-old man presented with typical trigeminal neuralgia (TN). Magnetic resonance angiography (MRA) revealed a primitive trigeminal artery (PTA) that came into contact with the trigeminal nerve. Based on MRA, we performed microvascular decompression (MVD). In the operational field, we confirmed the PTA location and performed MVD successfully. Postoperatively, the patient's pain subsided wi...

RE: Giant Cavernous Aneurysm Associated with a Persistent Trigeminal Artery and Persistent Otic Artery

Dear Editor, We have an interesting article by Zhang et al. (1), named “Giant Cavernous Aneurysm Associated with a Persistent Trigeminal Artery and Persistent Otic Artery”, which was published in the Sep/Oct 2009 issue of the journal. The patient in this report has an excellent outcome. However, we want to share more information about this case. After the completion of the first endovascular pr...

Giant Cavernous Aneurysm Associated with a Persistent Trigeminal Artery and Persistent Otic Artery

Primitive trigeminal artery (PTA) and primitive otic artery (POA) is a very rare entity in adult life. We present a case of PTA and POA associated with a giant unruptured cavernous aneurysm in a 54-year-old woman. The PTA and the POA arose from the sac of the aneurysm directly, which greatly complicated endovascular therapy management.
