Duplicated Anterior Choroidal Arteries: Literature Review and Clinical Implications.

The anterior choroidal artery supplies important cerebral structures. One important variation of this vessel is duplication. However, little is reported on this anatomical variant and moreover, the prevalence of such a finding varies widely. Therefore, here, we review the literature regarding duplicated anterior choroidal arteries. Clinicians reviewing imaging of the brain, interventionalists, or neurosurgerons should be knowledgeable of variations of the anterior choroidal artery, including its duplication. A better understanding of this anatomy and embryology can improve diagnoses and patient outcomes following interventional or open neurosurgical techniques.
