AN ANATOMICAL STUDY ON THE DISTRIBUTION OF ANEURYSMS INVOLVING THE ANTERIOR COMMUNICATING ARTERY AND THE PRECOMMUNICATING SEGMENT OF ANTERIOR CEREBRAL ARTERY IN THE POPULATION OF ASSAM

Abstract :

In a post–mortem, dissection study of 109 ains belonging to the population of Assam which includes 19 ains belonging to the Tribal population(T) and the rest 90 ains belonging to the Non–tribal population (NT) ; the Anterior Communicating Artery(ACoA) and ACoA–A1(pre–communicating segment of Anterior Cereal Artery) junction were examined for the presence and distribution of aneurysms .Photographic records of aneurysms were kept and relevant data were statistically analysed using SPSS(version 16). Saccular aneurysms involving ACoA and ACoA–A1 junction were present in 12.8% of the ains.Statistically significant difference (P=0.000) of aneurysms involving the left A1–ACoA junction were present between Tribal and Non–Tribal populations of Assam. Multiple aneurysms in the ACoA and A1–ACoA junction were present in 6.4% of the population. A study of this nature is potentially of value to the Neurosurgeons and Vascular Surgeons practising in this region.
