      THE ANATOMICAL CHARACTERISTICS OF THE VERTEBRAL ARTERY (Abstract): The present study was realized on a number of 137 cases, being used the dissection method and the angiogaphical study of the CT. The distance of the origin of the right vertebral artery in relation with the brachiocephalic trunk was 4.0-25.1 mm and the distance of the left vertebral artery in relation with the origin of the subclavian artery from the aortic arch had a value of 28.8-52.1 mm. At the origin, the left vertebral artery forms with the left subclavian artery an angle with a value of 30˚-70˚. The right vertebral artery in relation with the origin from the subclavian artery forms with the brachiocephalic trunk an angle with a value of 52˚- 90˚, having the same trajectory as the left vertebral arteries. The most voluminous external diameter of the vertebral artery was found on the left side, with a value of 2.0-3.5 mm and the right vertebral artery had a diameter of 1.8-2.9 mm. The horizontal endoarterial diameter at the level of the left vertebral artery had a value between 3.8 - 6.2 mm and the vertical one a value between 5.4-7.6 mm. In all our cases the vertebral artery entered into the transversal canal at the level of the C6 vertebra.
