First described by and named after the German pediatrician Johann Otto Leonhard Heubner in 1872, the medial striate artery or recurrent artery of Heubner is a branch of the anterior cerebral artery, most often originating near the division of the anterior communicating artery. Though very small in diameter (~0.8 mm), it supplies blood to multiple structures including the head of the caudate (“tail”), medial portion of the globus pallidus, anterior limb of the internal capsule, nucleus accumbens, and the basal nucleus of Meynert. While classically assumed to be a single vessel, up to 75% of patients have multiple (up to four) arteries of Heubner branching off the same anterior cerebral artery.
