Introduction: Introduction: The knowledge of cerebro-vascular variations is essential to the Radiologists, Neurologists, Neuro surgeons and Anatomists. The Anterior Cerebral Artery (ACA) which is a smaller terminal branch of Internal Carotid Artery (ICA) is known for its Aplastic and Hypoplastic variations which can surprise the surgeon on the operation table.
Aim: To evaluate and identify the aplastic and hypoplastic variations of ACA in Telangana population.
Materials and Methods: The present retrospective study was conducted by studying meticulously 150 Angiograms collected for a period of Jan 2017 to Jun 2018. In this study 1.5 Tesla MRI Machine (AVANTO of SIEMEN ltd.,) was used. Magnetic Resonance Angiogram (MRA) is used to detect all the possible vascular variations like aplasia, hypoplasia, aneurysms, infarct and thrombosis of cerebral blood vessels. After the collection of data it was tabulated and statistically analysed. The data was compiled and descriptive analysis was done.
Results: The present study was conducted on 150 cerebral angiograms obtained from the people of Telangana. Six angiograms (4%) showed variations of ACA. Aplasia of ACA was seen in three cases. Bilateral aplasia was seen in one case. Unilateral aplasia (Right side) was seen in two cases. Hypoplasia of ACA was seen in three cases which were all unilateral (Left side).
Conclusion: In the present study, the incidence of aplasia and hypoplasia of ACA was 4%, aplasia was observed in three angiograms (2%) and hypoplasia was observed unilaterally on the left side in three angiograms (2%). This study also involves examination of MRI and MRA for the incidence of various variations like aplasia, hypoplasia of ACA.
