1. Definition
The recurrent artery of Heubner is a branch of the anterior cerebral artery (anterior cerebral artery) that usually descends laterally from the proximal A2 segment or distal A1 segment - shortly after the branch of the anterior communicating artery.
2. Anatomy
The vascular territory of the recurrent artery of Heubner is the anteromedial segment of the caudate nucleus and the anteroinferior segment of the internal capsule, as well as parts of the putamen and the septal nuclei.
3. Pathology
Obstructed blood flow in the recurrent artery of Heubner (e.g. due to an embolism after clipping of an aneurysm) can cause single infarcts in these subcortical areas and subsequently hemiparesis.
