A STUDY ON ANATOMICAL AND MORPHOLOGICAL VARIATIONS OF THE ORIGIN OF LEFT VERTEBRAL ARTERY FROM THE ARCH OF AORTA
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2015, Vol 4, Issue 30
Abstract
The anatomic and morphologic variations of the left vertebral artery are significant for diagnostic and surgical procedures in the head and neck region. This study was conducted on 30 cadavers (Male-25, female-5) during routine dissection in the Department of Anatomy. Origin, course and termination of left vertebral artery from the arch of aorta were observed. Diameters at various level (1st, 2nd, 3rd & 4th part) and length of the prevertebral part of left vertebral artery were measured. Results showed, the average diameter of left vertebral artery that took origin from arch aorta was 5.4mm and average length of prevertebral part of left vertebral artery is about 7.2 cm. The narrowest part of the left vertebral artery was 2nd part and its average diameter was 4.7mm. These measurements are helpful in identifying the difficulties in catheterization and angiographic studies.
