Two other arteries are given off from the first part of the subclavian artery the internal thoracic artery and the thyrocervical trunk. Basilar artery aneurysms are less common than anterior circulation aneurysms and rupture less frequently but their critical location necessitates careful evaluation. The brainstem plays a role in regulating several vital functions including heart rate eating sleeping and breathing.

The basilar artery carries oxygenated blood to the cerebellum brainstem and occipital lobes. May present as a lobulated hyperattenuating structure anterior to the mid brain. The pcas are the terminal branches.
