Congenital Absence of the Right A1 Segment and the Anterior Communicating Artery: A Previously Unreported Variant of the Circle of Willis

2025-12-08

Abstract excerpt

<title>Abstract</title> <p>Background Variations of the Circle of Willis are common, but the combination of complete agenesis of a unilateral anterior cerebral artery A1 segment and absence of the anterior communicating artery (AComA) is exceptionally rare. Recognition of such patterns is essential for accurate radiologic interpretation and neurosurgical planning. Methods We describe a congenital CoW variant dete...
