Abstract
Purpose
The anterior perforating arteries are a group of arteries that enter the brain through the anterior perforated substance (APS). Because the lenticulostriate artery, the recurrent artery of Heubner (RAH) and the perforators from A1 of anterior cerebral artery (ACA) penetrate the APS and supply the basal ganglia, these arteries can be considered as having a common embryological origin.
Results
During development, the lateral striate arteries are divided from the lateral olfactory artery and divided into the RAH and middle cerebral artery (MCA). The RAH is a fascinating artery for its early development and variations of origin and course. The MCA has also several variations, such as the duplicated MCA, accessory MCA, and fenestration.
Conclusion
We provide a review of embryologic development and anatomical variations of the RAH, the perforators to the APS and MCA as a group of the lateral striate artery.
