“…However, hemorrhage of a dilated AChA can even occur in children. For instance, in 1991, Kameyama et al reported an 8-year-old girl who presented bilateral intraventricular hemorrhage from a dilated AChA 55 . In addition, an aneurysm could develop from an outpouching of the vessel wall in some fragile portions of the artery that function in maintaining prominent collateral circulation 56 .…”

“…An encephaloduroarteriosynangiosis was performed to decrease the hemodynamic overload on the AChA, and the follow-up procedure successfully induced the regression of all the weak points 53 . Furthermore, Kameyama et al reported an 8-year-old girl with an intraventricular hemorrhage from the dilated AChA who received a ventriculoperitoneal shunt, and an encephalomyosynangiosis prevented recurrent bleeding for over 6 years 55 .…”

The anterior choroidal artery (AChA) is a critical artery in brain physiology and function. The AChA is involved in many diseases, including aneurysm, brain infarct, Moyamoya disease (MMD), brain tumor, arteriovenous malformation (AVM), etc. The AChA is vulnerable to damage during the treatment of these diseases and is thus a very important vessel. However, a comprehensive systematic review of the importance of the AChA is currently lacking. In this study, we used the PUBMED database to perform a literature review of the AChA to increase our understanding of its role in neurophysiology. Although the AChA is a small thin artery, it supplies an extremely important region of the brain. The AChA consists of cisternal and plexal segments, and the point of entry into the choroidal plexus is known as the plexal point. During treatment for aneurysms, tumors, AVM or AVF, the AChA cisternal segments should be preserved as a pathway to prevent the infarction of the AChA target region in the brain. In MMD, a dilated AChA provides collateral flow for posterior circulation. In brain infarcts, rapid treatment is necessary to prevent brain damage. In Parkinson disease (PD), the role of the AChA is unclear. In trauma, the AChA can tear and result in intracranial hematoma. In addition, both chronic and non-chronic branch vessel occlusions in the AChA are clinically silent and should not deter aneurysm treatment with flow diversion. Based on the data available, the AChA is a highly essential vessel.
