Introduction: The anterior communicating artery complex consists of two anterior cerebral arteries (ACA), the anterior communicating artery (AComA) and the recurrent arteries of Heubner. ACA is divided into the three segments; A1 originating from the internal carotid artery, A2 extending from AComA and A3 also known as the pericallosal artery. The anatomical variations of the ACoA complex are not adequately discussed. The aim of this study is to detect the anatomical variations in the ACoA complex in patients that don’t have any intracranial vascular pathology. Aims: The present study determines the anatomical Variations of the anterior communicating artery complex. Patients and Methods: The study group consists of 70 subjects, using Digital Subtraction Angiography and Computed Tomography Angiography to visualize the vascular anatomy. Results: About 14.29% (10 patients) Aplastic ACoA, 7.14% (5 patients) have unilateral A1 ACA segment hypoplasia, 2.86% (2 patients) have unilateral A1 ACA segment aplasia. Conclusion: The most common anatomical variant is Aplastic ACoA.
