Transcranial sonography in a patient with a persistent trigeminal artery.
Transcranial ultrasonography was performed in a patient with a persistent trigeminal artery, a remnant of fetal cerebral circulation that bridges the carotid and basilar territories. The study revealed low flow and reversal of flow in the vertebral and basilar arteries, respectively. The interpretation and significance of these findings are discussed.
