Syncope Associated with a Congenital Variant of the Circle of Willis: Absence of the Right Anterior Cerebral Artery and Anterior Communicating Artery

2025-09-24

Abstract excerpt

<title>Abstract</title> <p> <bold>Background:</bold> Syncope is a transient loss of consciousness caused by global cerebral hypoperfusion. Although most commonly attributed to vasovagal or cardiac etiologies, anatomical variants of the Circle of Willis may alter cerebral hemodynamics and, in rare cases, contribute to syncope. <bold>Case presentation:</bold> We report the case of an 18-year-old female patient...
