| Summary: | 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. |
