Abstract The subclavian artery’s are two voluminous artery’s, left and right, which have their origin in a different way, the right one originating from the brahiocefalic trunk, and the left one directly from the aortic arch, at a distance that varies according to the origin of the left common carotid arteries. Our study was made on computed tomography angiography, on which we have had the opportunity to examine the scans from Medimar Imagistic Center, in the County Clinical Hospital “Sf. Andrei” in Constanta, being carried out on a computer tomography GE LightSpeed 16 slice CT. Also, we had available angiography’s executed in the center for diagnosis Pozimed, being carried out on a computer tomography GE LightSpeed VCT64 Slice CT. The variability of the findings in the anatomical parts of the subclavicular artery’s ostium, both as regards the size of the horizontal and vertical diameters, also their shape and as regards morfological relations with other branches of the aortic arch. The dimensions of the diameters vary according to sex, but it is a general rule that the dimensions are higher in male, the minimum and maximum values may be different in the two sexes.

Background: Gerbils (Meriones unguiculatus) are rodents belonging to the Muridae family. Recently, breeding of this species as pets has increased significantly. Animal models are being investigated to study diseases related to the human aortic arch. Despite the importance of the aortic arch in maintaining homeostasis, there is limited data available regarding its morphology in gerbils. This study was performed with the objective of describing the collateral branches of the aortic arch in this animal to establish a standard model and thus contribute to future research on cardiovascular diseases in humans.Materials, Methods & Results: This study used 20 male specimens from previous studies that were frozen and stored at the Laboratory of Veterinary Anatomy of the Federal Rural University of the Semi-Arid Region. After thawing the animals, the thoracic cavity was opened for aortic cannulation. The vascular system was washed using saline solution and Neoprene latex stained with red pigment was injected. Subsequently, the animals were fixed in 10% formaldehyde and were dissected and analyzed 72 h later. The arrangement of the collateral branches of the aortic arch in gerbils was analyzed in all animals. The brachiocephalic trunk, the left common carotid, and the left subclavian artery were observed to originate as collateral branches. The brachiocephalic trunk bifurcated into the right common carotid and the right subclavian arteries. The right and the left subclavian arteries branched into the vertebral artery, the internal thoracic artery, the superficial cervical artery, the costocervical trunk, and the axillary artery.Discussion: Several studies reported in the literature describe the collateral branches of the aortic arch in domestic and wild mammalian species. These studies examined the main arteries that originate directly from the aortic arch and their respective branches, and classified the different anatomical variants of the aortic arch in each species. Three different arrangements have been commonly described. The first type corresponds only to the brachiocephalic artery originating from the aortic arch. The right and the left common carotid arteries and the right and the left subclavian arteries originate from this brachiocephalic artery. This type has already been described in the laboratory rat, catingueiro-deer, cattle, and horses. The second type is characterized by the presence of 2 arteries - the brachiocephalic trunk and the left subclavian artery. The right and the left common carotid arteries and the right subclavian artery originate from the brachiocephalic trunk. This arrangement has been reported in most species already studied such as rodents including the paca, chinchilla, guinea pig, mocó, nutria and the preá. The third type of vascular arrangement is observed in the gerbil. In this species, 3 collateral arteries originate from the aortic arch (the brachiocephalic trunk, the left common carotid, and the left subclavian artery). The right common carotid and the right subclavian artery originate from the brachiocephalic trunk. This vascular model has been described in the manatee, in humans, mice, sauim, and the monkey-nail. Thus, we concluded that the branching pattern of the aortic arch of the gerbil was characterized by the brachiocephalic trunk, the left common carotid, and the left subclavian artery, as has been described in mice, the manatee, monkey-nail, sauim, and humans. Based on these morphological characteristics, gerbils could serve as potential experimental models to study diseases related to the human aortic arch.

Management of the symptomatic multiple stenosis of supra-aortic vessels (MSSVs) in a “bovine” aortic arch (BAA) configuration is infrequently reported. The optimal treatment choice remains debatable. A successful hybrid treatment for a proximal critical stenosis of the innominate and left common carotid artery was performed in a high-risk patient with a tandem symptomatic lesion in the right carotid bifurcation and a concentric vulnerable plaque in the bovine trunk. This case supports the feasibility, safety, and efficacy of a combined carotid bifurcation endarterectomy and retrograde kissing stenting of common carotid arteries with cerebral protection after evaluation of radiological, anatomical, and clinical parameters.

In this study, the aim was to investigate the anatomy of the aortic arch arteries in mole-rats (Spalax leucodon). Six adult mole-rats were used for this purpose. Coloured latex was injected into the left ventriculus of the hearts of all animals. The materials were carefully dissected and the arterial patterns of arteries originating from the aortic arch were examined. The brachiocephalic trunk, the left common carotid and the left subclavian arteries were detached from the aortic arch. The brachiocephalic trunk separated into the right subclavian and common carotid arteries. The branches separating from the subclavian arteries were on the right, the common branch giving the profund cervical, the internal thoracic, and the costocervical trunk, and on the left the internal thoracic and the costocervical trunk were in the common root and the profund cervical artery was independent and on both sides after giving the common branch of the superficial servical and the external thoracic artery. This continued as the axillary artery which was then separated into the subscapular and the brachial arteries. Thus, the arteries originating from the aortic arch and the branches of these arteries were found to be different from other rodents and domestic mammals.

This study was aimed at determining the vascular architecture of the aortic arch in the Eurasian bittern. For this purpose, the heart arteries of two bitterns were evaluated. The latex injection method was used to observe the branching of the aortic arch. Two brachiocephalic trunks were arising separately from the aortic arch and these arteries were giving to the common carotid and subclavian arteries. One of the thin branches arising from the subclavian artery was the sternoclavicular artery, which was in turn dividing into a sternal and a clavicular artery supplying the thoracic inlet and pectoral muscles. After the branching of the sternoclavicular artery, the axillary arteries were originating from the subclavian arteries. The thickest branch of the subclavian artery was the thoracic artery, which was dividing into internal and external thoracic arteries. Moreover, the brachiocephalic trunks were giving rise to the common carotid arteries and these were running cranially, giving rise to tracheosyringeal branches supplying the trachea and syrinx, thyroid artery, esophageal branches, artery of the comes nervi vagi and vertebral trunk. It is hoped that this study will enhance morphological data on exotic birds since the reports on species-specific vascular morphology in wild birds are insufficient and lacking in detail.

Most anomalies of the aortic arch arise due to the persistence of its parts that normally disappear, or due to the disapperance of parts that normally persist. We report a variant of aortic arch branching found on chest computerized tomography in a 75-year old Serbian man who had recurrent hemoptysis and an abnormal chest radiograph representing marked widening of the right superior mediastinum. Computerized tomography revealed a shared origin of the innominate and left common carotid arteries was found. This finding excluded tumor or pulmonary embolism as a cause of hemoptysis. The reason for hempotysis was anticoagulant therapy which patient had been receiving because of cardiovascula disease. We discuss the relative literature and underline the clinical impact of such a variation.

Atherosclerosis, as a civilization disease, is a serious epidemiological problem. Significant carotid disease and significant coronary artery disease result in acute consequences, such as ischemic stroke and myocardial infarction, which are the major causes of cardiovascular mortality. Typically, atherosclerosis of the aortic arch branches involves the bulbs of the common carotid arteries and the proximal segments of the internal carotid arteries, and can be effectively assessed by ultrasonography. Computed tomography angiography enables the identification of patients with less typical clinical manifestations of atherosclerosis, e.g., brachiocephalic trunk stenosis with symptoms of the steal syndrome and moderate stenosis in the coronary arteries. We present examples of computed tomography angiography images of this type of changes.

We present the case of a neonate born with an unusual complex vascular ring formed by a left-sided aortic arch that had retroesophageal course to join a right-sided descending aorta and a very large right-sided arterial ductus from the right pulmonary artery to the descending aorta. Associated finings included aortic arch hypoplasia, aberrant right subclavian artery, and aberrant origin of the left pulmonary artery from the aorta. We focus on the role of computed tomography angiography in the preoperative and postoperative assessment of this complex anomaly.
