Previous descriptions of these vessels are inconsistent and almost exclusively rely on cadaver studies.

PCA-origins were considered. Delineation, origin and number of branches of the collicular artery (CA), the accessory CA (ACA), the posterior thalamoperforating artery (PTA), the thalamogeniculate artery (TGA), and the posterior medial (PMCA) and lateral (PCLA) choroid arteries were assessed.

The PTA was delineated in 100%. In 27%, PTA anatomy had features of several Percheron types (<jats:italic>n<\/jats:italic>\u202f=\u20097) or vessels emanating from a\u00a0net like origin (<jats:italic>n<\/jats:italic>\u202f=\u20099). 26% had a\u00a0type\u00a0IIb PTA.
