Background: Thorough knowledge of anatomy of vertebral artery is essential to avoid inadvertent injury during surgery. The vertebral artery can have a variable course, especially in the upper cervical spine. Materials and Methods: Study area - Burdwan Medical College and Hospital. Study population - Cadaver at Anatomy and FSM Department. Sample size - Thirty-one cadavers. Study design - Institution-based prospective study. In this study, most of the dissection is done through midline incision to avoiding risk in damage to trachea and esophagus. All structures are bluntly dissected to reach the origin of vertebral artery. From there, the level of entry is dissected. Results: Out of 31 cadavers, male cadavers were 22 (71%) and female cadavers were 9 (29%). Anomalous vertebral artery entry found only in 3 (9.7%) cases. All anomalous entry was at C7 level. Vertebral artery entry at C6 foramen in 28 cases (90.3%). In all the 28 cases where vertebral artery entered at C6 transverse foramina, vertebral artery ascended from subclavian artery as it's first branch. Among 28 cases where vertebral artery entered at C6, 20 cases were males and eight cases were females. Out of three cases having C7 entry, two were male cases and one was female case. Altogether 9.7% of cases had C7 anomalous entry. Conclusion: In our study from 31 cadavers, we found 9.7% of cases have anomalous entry at C7 level. Although this is a small study with few cadaver number of anomalous connection is not small, and it is not at all rare.
