Cerebrovascular disease due to atherosclerotic involvement of the vertebrobasilar system accounts for one of the major causes of stroke. Intracranial vertebral arteries, one of the feeder vessels of the brain are one of the principal sites implicated. Qualitative and Quantitative histological features of the intracranial vertebral arteries were studied in healthy young adults during routine autopsies. Thirty pairs of vessels were processed for paraffin sectioning (young adults: 20-40 years). Seven micron thick transverse sections were stained with Hematoxylin and Eosin, Masson__ampersandsignrsquo;s Trichrome and Verhoeff__ampersandsignrsquo;s Stains and observed under the light microscope. The mean luminal diameter was more in left sided vessels whereas tunica intima was thickened more on the right side. Preatherosclerotic ageing changes were observed as early as the third decade of life in apparently healthy young individuals which is an alarming sign for young adults.
