“…2). This corresponds to the reports of left VA origin as a branch from the root of left SCA close to the AA [10] or of left VA "in touch" with left SCA [11]. This form of very close origin of VA and SCA by one specific common widening of AA we consider as not prop- originating region, in terms of one common or two separate openings of related vessels or of blood flow patterns in this region.…”

Vertebral artery (VA), the main element of the posterior brain circulation, has many anatomical variations which generally were widely investigated. However, available data vary in wide ranges, reflecting very different sample sizes, lack of data about left-right or sex differences, and about possible ethnic, regionally specific or genetic differences. Certain new findings suggest possible involvement of some environmental factors in VA variations. Accurate anatomical data about VA variations in different regions of the world, including Balkans countries, are still lacking. Therefore we investigated morphological variability of VA origin and its entrance level into cervical transverse foramina in population of Republika Srpska (Bosnia and Herzegovina), including data about the sex and side. Anatomy of VA was investigated in 112 persons (224 arteries) of both sexes (58 males, 54 females; age 19 - 83 years), using 64-slice CT scanner. Origin of VA from subclavian artery (SCA) we found in 95.08% of arteries (52 males, 49 females). Only in one male (0.45 %) left VA and left SCA had an specific origin from aortic arch (AA), which we named as an "common area of origin". All other observed variations in origin were only of left VA, originating from AA in 4.47 % (5 males, 5 females). Left VA Most often (usual) entrance level into transverse foramen we found at C6 (87.5%), followed by C5 (8.93 %), C4 (3.12 %), and in one case at level C7 (0.45 %). Entry levels at C5 both, on right and on the left side, were 3 times more frequent in males than in females. Wide ranges of differences between the data we obtained on a sample in Republika Srpska (Bosnia and Herzegovina) and the data from many other studies require further and wider investigations.

Objectives: An understanding of anatomy is essential to surgeons and knowledge of variations is of practical importance. The anatomic and morphologic variations of great vessels are significant for diagnostic and surgical procedures in the neck and thorax region. Vertebral artery is a branch of subclavian artery, generally arising from the first part of subclavian artery on both the sides. Multiple variations in the origin of vertebral artery have been reported in the literature, most common being directly from the arch of aorta, as a branch of thyrocervical trunk, as a branch of common carotid or external carotid artery.

“…The Inferior thyroid artery (ITA) is the chief artery which supplies the posterior and inferior parts of the thyroid gland and parathyroid glands [15]. The ITA is generally larger and the more important one from the point of view of occlusion to reduce the vascularity of goiters and a route for exposure of truncal ligation of this vessel has been worked out on the cadaver and practice [18]. CONCLUSION…”

Thyroid gland is the largest endocrine gland supplied by the superior, inferior thyroid arteries and occasionally by thyroid ima artery. Proper identification of thyroid gland vessels is very important in order to avoid major complications during and after neck surgeries. The objective of this study was to assess variations on arterial supply of thyroid gland and its clinical significance in human cadavers in selected universities of north Ethiopia.A descriptive survey study design was employed to assess the variations on arterial supply of thyroid gland in human cadavers. Sixteen formalin fixed cadavers were used during routine dissection for the medical teaching. Variations in morphological character observed in the arterial supply of thyroid gland was noted, recorded and photographed.In the present study it was observed that, the site of the origin of superior thyroid artery (STA) was evaluated as it arose from external carotid artery in 84.4%, from carotid bifurcation in 9.375% and from common carotid artery in 6.25% the cases. Regarding to the number of STA was observed that single in all specimens. In all specimens, the origin of ITA was from the thyrocervical trunk.The anatomic characteristics and variation of the Thyroid arteries shows the most common site of origin of superior thyroid artery is from external carotid artery, whereas Inferior thyroid artery arisen from thyrocervical trunk and thyroid ima artery is not found.
