Why is it important?
The aim of study was to present and describe the variant anatomical origins of the vertebral artery and its entrance into the cervical vertebra. The study material consists of 50 embalmed cadavers 9 females and 41 males at the Dr. D. Y. Patil Medical College, Nerul, Navi Mumbai. Out of which in 3 (6%) cadaverswere found where the left vertebral artery arises directly from the arch of aorta between the origins of the left common carotid and the left subclavian artery. In all cadavers right vertebral artery arises from the first part of right subclavian artery. These vertebral arteries coursed upward to the transverse foramen of cervical vertebra at different levels. Out of the 50 cadavers, the right vertebral arteries entered through transverse foramen of 6thand 5th cervical vertebrae 46 (92%) and 4 (8%) respectively. left vertebral artery entered through transverse foramen of 6th cervical vertebra in 44 (88%), while those of 5th and 4th in 4(8%) and 2(4%). The vertebral artery is important to posterior cerebral circulation so it is of clinical important to know the origin and course of the vertebral artery. The relation is important while performing transpedicular fixation or other spinal surgeries.
