Abstract

Background: Basilar artery is one of the import arteries of posterior part of the brain. It is clinically related to stroke, migraine
aneurysm, and atherosclerotic changes as age advances.
Materials and Methods: Fifty cadaveric brain specimens were studied for basilar artery. The origin and insertion were noted.
The diameter and length of the artery was measured with digital Vernier caliper.
Results: Mean length was 28.82 (SD±3.62) and range was 21.2–43.04. The mean diameter was 3.42 (SD±0.78), range was
2.08–4.82. Normal origin of artery was 45 (90%) and variations in the formation were 5 (10%). Normal insertion was 43 (86%)
and variations were 7 (14%).
Conclusion: This morphometric study indicates the variations in the length and diameter, variations in the origin, and termination.
As this artery correlated clinically with cerebrovascular disease these morpho –metric findings will enable the nuerophysician,
radiologist for proper diagnose and neurosurgeon to operate without any fatal outcome.
