<p><strong>Aim.</strong> Assessment of normal and variant aortic arch anatomy in patients with type A aortic dissection and aneurysm of the arch and descending thoracic aorta.</p><p><strong>Methods.</strong> We retrospectively studied computer tomography (CT) data of chest organs with contrast in patients who underwent reconstruction of the aortic arch in type I aortic dissection according to DeBakey classification (n = 61) and resection of the aortic arch and descending thoracic aorta aneurysm (n = 14) at the Meshalkin National Medical Research Center, Novosibirsk, Russian Federation. The control group included patients without aortic arch pathology (n = 52). To identify relationships between the anatomical type of aortic arch and the risk of aortic pathology development, univariate and multivariate binary logistic regression analyses were used.</p><p><strong>Results.</strong> Our analysis revealed four types of aortic arch anatomy. Normal aortic arch anatomy occurred in 66.1 % of patients (n = 84), the proportion of abnormalities of the left common carotid artery was 30 % (bovine aortic arch occurred in 15 %, and the same site of origin of left common carotid artery and brachiocephalic trunk occurred in 15 %). Divergence of the left vertebral artery from the aortic arch between the left common carotid and left subclavian arteries occurred in 3.1 % (n = 4), and the combination of “bovine trunk” and divergence of the left vertebral artery from the aortic arch was detected in 0.8 % patients (n = 1). Logistic regression analyses revealed no statistically significant relationships between variant aortic arch anatomy and the development of type A aortic dissections and aortic arch aneurysms. The presence of the common origin of brachiocephalic trunk and left common carotid artery was associated with a reduced risk of acute aortic dissection type I by 89 %, or an OR of 0.11 (95% CI: 0.03–0.46) (p = 0.002).</p><p><strong>Conclusion.</strong> Our data will help with future planning surgical interventions on the aortic arch and descending thoracic aorta.</p><p>Received 17 June 2020.

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.

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.

<p>We herein report the first clinical case of prosthetic replacement of the ascending aorta and aortic arch to repair a giant aneurysm in a 7-month-old child. The ascending aorta and arch replacement to the level of left subclavian artery was performed using a no. 16 Polymaille prosthesis, the brachiocephalic trunk was reimplanted into the vascular prosthesis and the kinked section of the left common carotid artery was removed, followed by reimplanting the left common carotid artery into the left subclavian artery. First, proximal anastomosis with the vascular prosthesis was created using a no. 16 Polymaille prosthesis and the vascular suture was strengthened with a Teflon strip. During circulatory arrest, the aortic arch was crossed between the orifice of the left common carotid artery and left subclavian artery, with the cut extended to the isthmus region along the small curvature of the arch. The brachiocephalic trunk was aligned and brought down, with subsequent implantation into the ascending aorta prosthesis 2 cm below the initial fixation point. In the final stage, the kinked section of the left common carotid artery was resected and the aligned left carotid artery was directly reimplanted into the left subclavian artery using end-to-side anastomosis. The patient developed tracheobronchitis and moderate heart failure during the postoperative period. The duration of mechanical ventilation was 16 hours. Infusion and antibacterial therapy were discontinued on postoperative day 8. On postoperative day 13, the patient was discharged and referred to the outpatient centre for further treatment and rehabilitation. A sufficiently large-sized prosthesis allows for further development in paediatric patients. This is facilitated by the preservation of the native aortic root with restored valve function and the formation of a bevelled distal anastomosis with a small unchanged aortic section in the isthmus region, which maintains growth potential. This first reported case of an infant demonstrates the possibility of combination interventions on the aortic arch and brachiocephalic artery during the first year of life.</p><p>Received 30 January 2021.

Abstract Although isolated left vertebral artery is a supra-aortic trunk variant, it is not so rare. It may pose additional difficulties during total arch replacement surgeries. The aim of this study was to present our experience with prior reconstruction of isolated left vertebral artery by isolated left vertebral artery–left common carotid artery during total arch replacement combined with stented elephant trunk implantation.

The paper describes a clinical case of successfully applying a transradial access during mechanical thrombus extraction in a patient in the acutest stage of ischemic stroke with a congenital anatomical feature (the left common carotid artery and brachiocephalic trunk with the common ostium from the aortic arch).X-ray endovascular interventions were performed in an operating room equipped with a digital angiographic unit including an Axiom Artis dTA flat detector (Siemens Medical System).Mechanical recanalization for acute occlusion of the M2 segment of the left middle cerebral artery (MCA) was carried out using a right radial access into and catheterization of the left internal carotid artery. A stent retriever was inserted into the occlusion area through a microcatheter and was opened. Double thrombus extraction from the left MCA was made using the stent retriever to restore TICI 2B blood flow. There were no signs of dissection, thrombosis, or distal thromboembolism.

Abstract Our study was conducted by the examination of angioCT’s, performing external measurements of aortic arch and the exo and endoaortic measurements of its three. The diameter of the thoracic aorta prior to the origin of the brachiocephalic arterial trunk was found with an average of 31.65 mm and below the left subclavian artery origin we found an average diameter of 24.3 mm. The brachiocephalic arterial trunk had an average diameter of 11.575 mm, 6.05 at carotid artery level and 9.05 mm at the level of the left subclavian artery. The endoaortic average diameter of the brachiocephalic arterial trunk: horizontally, 13.0 mm and vertically 11.7 mm; left common carotid artery horizontal diameter was 10.5 mm and 9.7 mm vertically and the left subclavian artery have 14.1 mm horizontally and 10.8 mm vertically.

The Vertebral Artery (VA) is classically described as originating as the first branch of the ipsilateral subclavian artery. The VA origin is variable and has been identified at the aortic arch, Common Carotid Artery (CCA), and Internal Carotid Artery. The VA arising from the carotid artery is an extremely uncommon variant. Left VA origin from the left CCA has been reported only thrice. These rare anomalous origins of the VA usually are asymptomatic. We describe symptomatic aberrant origin of left vertebral artery from left common carotid artery, a rare case.

Knowledge of the aortic arch branching pattern is important during supra-aortic angiography, aortic instrumentation, thoracic and neck surgery. The aortic arch (AA) is located in the superior mediastinum. In 65–80% of the cases, the three branches arise from the aortic arch, namely, the brachiocephalic trunk (BCT), the left common carotid artery (LCCA), and the left subclavian artery (LSA). The purpose of this study is to describe different branching patterns of the arch of the aorta in Indian subjects. This observational study is based on dissection performed on Sixty embalmed arches of the aorta in adult Indian cadavers (in manuscript it was written as, 20 dissected heart specimens were collected of still-born fetuses) were exposed and their branches examined during cadaveric dissection in the department of Anatomy. The anatomical variations of the arch of the aorta and its branches, its branches at site of origin, and the distance of each branch from the point of origin to the median plane were measured. The usual three-branched pattern of arch of aorta was found in 44 specimens (73.33%). The common trunk for both brachiocephalic trunk and left common carotid artery was present in 11 specimens (18.33%). In 2 specimens (3.33%), the arch gives four branches. In 1 specimen (1.67%), give three branches. The wide spectrum of variations in the anatomical arrangement of the human aortic arch and its branches offer valuable information to catheterize the aortic arch and its branches for safely performing endovascular surgery. These anatomical and morphologic variations in the arch of the aorta and its branches are significant for diagnostic and surgical procedures in the thorax, head and neck regions.
