Endovascular Reconstruction of a Stenotic Persistent Primitive Trigeminal Artery Causing Hemodynamic Vertigo: A Case Report

Atherosclerotic stenosis of a persistent primitive trigeminal artery is an exceptionally rare cause of posterior circulation hypoperfusion. A 48-year-old woman with hypertension and hyperlipidemia presented with recurrent, disabling rotational vertigo despite six weeks of aggressive medical therapy....

No actionable change for most audiologists — this single case report describes a rare vascular cause of vertigo managed by neurointerventional radiology, not audiology.

This case highlights that vascular causes of vertigo (dizziness) can mimic inner-ear disorders, reinforcing the importance of thorough differential diagnosis in patients with persistent or unusual dizziness.

1. 01Single case report of hemodynamic vertigo caused by a persistent primitive trigeminal artery (a rare congenital blood vessel).
2. 02Patient was a 48-year-old woman with posterior circulation hypoperfusion (reduced blood flow to the back of the brain).
3. 03Endovascular reconstruction (a minimally invasive procedure to open the narrowed vessel) resolved the vertigo.
4. 04Persistent primitive trigeminal artery is an uncommon anatomical variant that can cause vascular vertigo.
5. 05Clinicians should consider vascular etiologies in atypical or treatment-resistant vertigo presentations.
