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.

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.

Abstract Background Congenital anomalies of the aortic arch are important as they may be associated with vascular ring anomalies. The most common vascular ring anomaly in dogs is a persistent right aortic arch. However, published data of the distribution of the different types of vascular ring anomalies and other aortic arch anomalies are lacking. The objective of this retrospective descriptive study was to evaluate both the prevalence and the different types of aortic arch anomalies that can be detected using thoracic computed tomography (CT) examination. Archived thoracic CT examinations acquired between 2008 and 2020 at a single institution were retrospectively evaluated by 2 evaluators for the prevalence and type of aortic arch anomaly. Breed, age, and presenting complaint were obtained from the medical record system. Results A total of 213 CT studies were evaluated; 21 dogs (21/213, 9.9%) showed a right aortic arch and a left ligamentum arteriosum with compression of the esophagus. The following incidental additional findings were detected: aberrant left subclavian artery (17/21, 76.2%), branching from the persistent ductus arteriosus (PDA) (1/21, 4.8%), left-sided brachiocephalic trunk (3/21, 14.3%), bicarotid trunk (17/21, 81.0%), double aortic arch (1/21, 4.8%). One hundred ninety two dogs (192/213, 90.1%) showed a left aortic arch without esophageal compression. The following additional abnormalities were obtained in those dogs with left aortic arch: aberrant right subclavian artery (3/192, 1.6%) without clinical signs of esophageal compression, aberrant vessel branching from the aorta into the left caudal lung lobe (2/192, 1.0%), focal dilatation of the left or right subclavian artery (2/192, 1.0%), bicarotid trunk (1/192, 0.5%). Conclusion Similar to previous studies an aberrant left subclavian artery is the most common additional finding in dogs with persistent right aortic arch. Newly, a left-sided brachiocephalic trunk was identified in 14.3% of the dogs with a persistent right aortic arch; no additional compression was caused by the left sided brachiocephalic trunk. Similarly, aberrant right subclavian artery can be an incidental CT finding without causing compression of the esophagus.

AbstractThe right aortic arch is a congenital vascular anomaly, which may form a vascular ring. However, prenatal identification of the branching pattern of brachiocephalic vessels is often limited. In this paper, we clearly demonstrated the branching pattern of brachiocephalic vessels in a case of right aortic arch with an aberrant left subclavian artery using HDlive Flow imaging.

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.

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.

AbstractPurpose: The aim of this study was to investigate the frequency and gender distribution of variations in the aortic arch branching pattern using 64-slice computed tomograhic angiography. Materials and methods: A total of 1000 patients with a normal left-sided aortic arch who underwent computed tomographic angiography for various reasons were analysed retrospectively for the frequency of variation of aortic arch branching; the variations were categorised into seven types. Results: Of the 1000 patients, 79.2% had a normal aortic arch branching pattern – type 1 – and 20.8% had variations. The frequency of type 2 variation – brachiocephalic and left common carotid arteries arising from the aortic arch in a common trunk – was 14.1%, that of type 3 – left vertebral artery originating from the aortic arch – was 4.1%, that of type 4 – coexistence of type 2 and type 3 – was 1.2%, that of type 5 – aberrant right subclavian artery – was 0.6%, that of type 6 – coexistence of aberrant right subclavian artery and bicarotid trunk – was 0.7%, and that for type 7 – thyroidea ima artery arising from the aortic arch – was 0.1%. The incidences of the variations of aortic arch branching were similar among males and females (20% versus 22.1%). The incidence of an aberrant right subclavian artery – type 5 and type 6 – was higher among females compared with males (2.5% versus 0.5), whereas the frequencies of the other variations were either equal or similar in both genders. Conclusion: Recognition of variations of aortic arch branching is important because they may cause symptoms due to tracheoesophageal compression or complications during surgical or endovascular interventional procedures of the aorta and its branches.
