Introduction: The variation in the aortic arch is well known and it has been demonstrated by number of researchers. Changes involved in the development of aortic arch system such as regression, retention or reappearance result in the variation in branching pattern of aortic arch. Variations of the branches of aortic arch are due to alteration of branchial arch arteries during embryonic period. The most common classical branching pattern of the aortic arch in humans comprises of three great vessels, which includes Brachiocephalic trunk, Left Common Carotid artery and Left Subclavian artery. Aim: The study is to determine the embryological basis correlating with clinical application and surgical procedures. Materials and Methods: A study was conducted in 50 formalin fixed cadaveric hearts, during a period of two years. In the routine dissection for 1st MBBS and also museum specimens we encountered 3variations in the branches of arch of aorta. Results: The variations in aortic arch branching pattern were observed in 4 cadaveric hearts (8%). Conclusion: The wide spectrum of variation in the human aortic arch and its branches offer valuable information to catheterize in endovascular surgery for diagnostic and surgical procedures in the thorax, head and neck regions. KEY WORDS: Aortic Arch (AA), Left Common Carotid (LCCA), Left Subclavian (LSA), Brachiocephalic Trunk (BCT), left vertebral artery(LVA).

In human beings the most common branching pattern of the aortic arch was its division into three great vessels ie the brachiocephalic trunk, left common carotid artery and the subclavian artery. The vertebral arteries arise from the superior aspect of the first part of the subclavian artery. In present case, a left vertebral artery arose from the aortic arch as fourth branch was found. The diameter of left vertebral artery at its origin was 6 mm as compared to the right vertebral artery, which has diameter of 3.5 mm at its origin. In this case left sixth dorsal intersegmental artery might have persisted as first part of vertebral artery hence left vertebral artery arising from arch of aorta. Knowledge of the variations in branching pattern of the aortic arch is important in the diagnosis of intracranial aneurysm after subarachnoid haemorrhage.J. Biomed. Sci. 2015, 2(3):21-23.

Abstract Background and aim: Study of variation in branching pattern of arch of aorta is important for cardio­ vascular surgeons to avoid injury during procedures like angiography and stenting of aorta. These variations are frequently encountered during surgical procedures, as a developmental alteration in branchial arch during embryonic period. The aim of present study is to describe variation in branching pattern of arch of aorta belonging to Gujarati population and these results will be of significance for anatomists for relating it with embryological basis, cardiovascular surgeons and radiologists. Materials and metbods: Forty embalmed cadavers were observed for study of branching pattern of arch of aorta during period of four year in Department of Anatomy in Smt N.H.L.Municipal Medical College, Ahmedabad. Results: In the present study, normal branching pattern of the arch of aorta was found in 92.5% cases. In 2.5% cases only two vessels originated from the arch of aorta, one of them was common trunk for brachiocephalic trunk and left common carotid artery and the second trunk was left subclavian artery. In 5% of cases four vessels arose from arch of aorta, the left vertebral artery arose directly from aorta with normal branching pattern. Conclusion: Vascular invasive procedures are increasing since last decade. So knowledge of variation in branches of arch of aorta is essential for cardiologist, cardiovascnlar surgeon as well as for radiologist.

Variations of the branches of aortic arch are due to alteration in the development of certain branchial arch arteries during embryonic period. Knowledge of these variations is important during aortic instrumentation, thoracic, and neck surgeries. In the present study we observed these variations in fifty-two cadavers from Indian populations. In thirty-three (63.5%) cadavers, the aortic arch showed classical branching pattern which includes brachiocephalic trunk, left common carotid artery, and left subclavian artery. In nineteen (36.5%) cadavers it showed variations in the branching pattern, which include the two branches, namely, left subclavian artery and a common trunk in 19.2% cases, four branches, namely, brachiocephalic trunk, left common carotid artery, left vertebral artery, and left subclavian artery in 15.3% cases, and the three branches, namely, common trunk, left vertebral artery, and left subclavian artery in 1.9% cases.

Understanding the great vessels of the aortic arch and their variations is important for both the endovascular interventionist and the diagnostic radiologist. An understanding of the variability of the vertebral artery remains most important in angiography and surgical procedures where an incomplete knowledge of anatomy can lead to serious implications. In the present case, a bilateral variation in the origin and course of vertebral artery was observed. The left vertebral artery took origin from the arch of aorta and entered the foramen transversarium of the fourth cervical vertebra. The right vertebral artery took origin from the right subclavian artery close to its origin and entered the foramen transversarium of the third cervical vertebra. The literature on the variations of the artery is studied and its clinical significance and ontogeny is discussed.

Objectives. The aim was to determine the prevalence of aortic arch variations in 881 patients who underwent neck CT angiography for various reasons. Material and Methods. 881 patients were included in the study who had undergone neck CT angiography between 2010 and 2013. Results. Of 881 patients, 770 (87.4%) patients with classic branching pattern of the aortic arch (AA) were observed. Variations in branching pattern were seen in 111 (12.6%) patients. The most common variation was the origination of the left common carotid artery (LCCA) from the brachiocephalic trunk (BCT). This pattern was observed in 64 (7.2%) cases. In 25 (2.8%) cases, the left vertebral artery (LVA) originated directly from the AA between the origin of the LCCA and left subclavian artery (SCA). 17 (1.9%) cases had aberrant right subclavian artery. Three (0.3%) cases showed right aortic arch. Two cases had right aortic arch with aberrant left subclavian artery. Conclusions. Variations in the branching pattern of the AA are not rare. Head and neck surgeons and interventional radiologists should be aware of aortic arch variations. CTA is a reliable imaging method for demonstrating anatomical features and variations of the AA.

Abstract Background and aims: Study of branching pattern of arch of aorta and its variation is very significant. This study helps in avoiding the surgical, accidental injuries of blood vessels during cardiovascular surgeries and radiological procedures. Present study is aimed at finding out the branching pattern of arch of aorta, variations of its incidence, clinical significance and to correlate its embryological basis. Materials and methods: Present study was conducted on 30 formalin fixed cadavers, which were allotted to the undergraduate students of Bangalore Medical College and Research Institute. A comparative analysis was done with previous studies. Results: Usual three-branched aortic arch was found in 23 cadavers (76.66% ); variations were found in seven cadavers (23.33% ); 10% presented left vertebral artery arising directly from the arch of aorta; 6.66% presented common trunk of left vertebral artery and left subclavian artery; 3.33% presented thyroidea ima artery arising from the arch; 3.33% presented common trunk of brachiocephalic trunk and left common carotid artery. Conclusion: Variations observed in present study were in par with the variations observed by previous studies. Although anomalous origins of the aortic arch branches very rarely produces clinical symptoms but their knowledge is necessary for operating surgeons and interventional radiologist to avoid complications in the thorax, head and neck region.

Abstract The aortic arch usually gives off three major arterial branches: the brachiocephalic trunk, the left common carotid artery and the left subclavian artery. The most frequently occurring developmental variations of arterial trunks origins are a joined brachiocephalic and left common carotid artery origin, the left vertebral artery branching from the aortic arch, a double aortic arch, and a change of sequence of branching arteries. The current report presents the rare asymptomatic situation of the right subclavian artery originating as the last individual branching from the aortic arch. This abnormality was accidentally discovered in a computed tomography examination of a 69-year old male patient. The examination showed that the artery went towards the neck posteriorly from the trachea. The anatomical anomaly was interpreted as being an arteria lusoria.

Introduction The present article presents a rare case of variation of the left vertebral artery, which originated from the aortic arch, between the common carotid artery and the subclavian artery, although classic descriptions of the vertebral artery indicate its origin at the subclavian artery, where it penetrates the foramen transverse and ascends cervically to the foramen magnum. Case presentation The anatomical peculiarity of the vertebral artery is evidenced. The origin of the vertebral artery was identified directly from the aortic arch in a dissected human specimen. Conclusion In view of the numerous surgical procedures performed in this area, the clear understanding of its topographic layout is indispensable, and might change surgical procedures performed in the region.

Abstract Our study was performed on 228 cases by dissection, by plastic injection followed by corrosion or dissection and by simple and CT angiography study. Each morphological aspect was assessed on a different numbers of cases, as long as the same case could not provide data on all studied elements. We assessed: the number of branches that originate from the aortic arch, the level of origin and the morphological type of the aortic arch. In terms of number of branches emerging from the aortic arch, most commonly are three branches, in 48.48% of cases, describing them 3 variations: separation of the three classical branches in 45,96% of cases, in 1.51% of cases the left common carotid artery emerged from the brachiocephalic trunk while the other two branches being represented by a vertebral artery and the left subclavian and in 1.01% by the right subclavian artery with retroesophageal traject, by a bicarotid arterial trunk and the left subclavian artery. In 28.70% of the cases were four branches, as follows: in 13.13% of cases the fourth branch was represented by the left vertebral artery, in 7.07% of cases there was the inferior thyroid artery, in 4.04% of cases the brachiocephalic arterial trunk was missing and the right subclavian artery originate from the aortic arch and presented a retroesophageal traject, in 3.03% of cases the fourth artery was the ascending cervical and in 1.51% of cases all four arteries had their origins in the aortic arch with no brachiocephalic trunk. In 22.73% of cases from the aortic arch originated only two branches: in 19.70% of cases the left common carotid originated in the brachiocephalic trunk, so the second branch was the left subclavian and in 3.03% of the cases there were two brachiocephalic trunks. Regarding the level of origin from the aortic arch, we found that only the brachiocephalic arterial trunk showed versions of origin: in 64 61% of the cases the brachiocephalic trunk had its origin in the horizontal segment of the aortic arch, in 21.54% of cases the origin was located at the limit between the ascending and horizontal segments and vin 12.31% of cases the origin was from the ascending segment of the aortic arch. In only 1.54% of the cases the left subclavian artery originated from the descending segment of the aortic arch

Variant Anatomy

Background: Variant branching patterns of the aortic arch are not infrequent but are commonly under reported. This study was conducted to determine the spectrum of Variant branching pattern of aortic arch and their prevalence using contrast enhanced computed tomography (CECT) images of the cases from a tertiary care centre.Methods:  Contrast enhanced computed tomography (CECT) images of aortic arch region from 1116(629 male and 487 female) cases from 18 to 85 years of age were examined retrospectively. The images were reviewed for normal and variant anatomy of aortic arch and the results were analyzed statistically.Results: Of 1116 patients, 878 (78.6%) cases showed normal and 238 (21.3%) cases had variant branching pattern of the aortic arch. The most common variation was the common origin of brachiocephalic trunk (BCT) and the left common carotid artery (LCCA) which was observed in 160 (14.3%) cases. In 8 (0.7%) cases, BCT and LCCA took origin from a single common trunk arising from the aortic arch. In 60(5.4%) cases, the left vertebral artery (LVA) originated directly from the aortic arch between the origin of the LCCA and left subclavian artery (SCA). 8 (0.7%) cases had aberrant right subclavian artery. Two (0.2%) cases showed right aortic arch.Conclusions: Interventional radiologists and surgeons should be well aware of variant anatomy of aortic arch. Contrast CT is a highly reliable imaging method for demonstrating anatomical features and variations of the arch.
