- adj. Of, pertaining to, or affecting both the vertebral and basilar arteries
Sorry, no etymologies found.
The primitive trigeminal artery (PTA) is the most commonly described fetal anastomosis between the carotid and vertebrobasilar circulations.
Example: make your first laparoscopic incision to the upper quadrant of the right occipital lobe, avoiding palpitation of the hypothalamus, ablation around the left and right anterior paretial cortex and extending your arterio-venous fistula into the vertebrobasilar Medulla Oblongata (kids, don't try this at home - I made it up).
