The pontine branches are the small arterial branches of the basilar artery that supply the pons and structures adjacent to the pons.
There are usually 3-5 paired arterial branches which are located in the mid-basilar region between the anterior inferior cerebellar artery and the superior cerebellar artery 1,2.
These branches can be divided into multiple groups based on their origin and course 3.
type 1: paramedian branches
type 2: short circumflex branches
type 3: composition of the paramedian and the short circumflex branches
type 4: long circumflex branches
type 5: median branches penetrating the pons along the basilar sulcus
In general, occlusion of any one of these branches results in unilateral pontine infarcts that do not cross the midline 4.
