This article is from The Korean Journal of Pain, volume 27.AbstractBackground: Knowledge of the anatomical variation of the vertebral artery has clinical importance not only for the performance of interventional or surgical procedures itself but also to ensure their safety. We conducted a study of the anatomical variation by reviewing multi-detector computed tomography MDCT images of the cervical spine from 460 Korean patients. Methods: 16-row MDCT data from 460 patients were used in this study. We observed 920 vertebral arteries. Examination points included level of entrance of the artery into the transverse foramen of the cervical vertebra, origin site of the vertebral artery, course of a vertebral artery with aberrant entrance. Result: The vertebral artery in 2 0.2% cases in this study entered into the transverse foramen of the 7th cervical vertebra from the left. In 45 4.9% cases, the vertebral artery entered into the transverse foramen of the 5th cervical vertebra. Of these, the entrance was on the right in 15 1.6% and on the left in 30 3.3%. We found 17 1.8% cases in which the artery entered into the transverse foramen of the 4th cervical vertebra, 10 1.1% on the right and 7 0.7% on the left side. As is commonly acknowledged, the 6th cervical vertebra was the most common site of entry; the vertebral artery entered the transverse foramen of the 6th cervical vertebra in the remaining 855 93.0% cases, on the right in 434 47.2% and on the left in 421 45.8%. Conclusions: In conclusion, the possibility of an atypical course of the vertebral artery in segments V1 and V2 should be evaluated with magnetic resonance imaging MRI or CT images before carrying out procedures involving the anterior cervical vertebrae.
