BACKGROUND: Prevalence of bicuspid aortic valve (BAV) and right aberrant subclavian artery (ASA) separately is relatively common in general population, and much higher in some disorders. Surprisingly, coexistence of both valve and vessel anomalies has only been reported in single cases. METHODS: From 2008 to 2016, in a single, high-volume tertiary cardiac center, patients who underwent chest computed tomography or magnetic resonance imaging for various reasons, were retrospectively screened for the presence of right ASA...

A 10-year-old dog weighing 3.4 kg presented with intermittent regurgitation. Esophagography revealed that the thoracic esophagus was compressed dorsally at the region of the fourth intercostal space and segmentally dilated from the second to third intercostal region. Three-dimensional computed tomographic (CT) angiography confirmed a suspected vascular ring anomaly and also revealed multiple other vascular anomalies. These included aberrant right subclavian artery, absence of bilateral external jugular veins, right-gastric caval shunt, and a completely duplicated caudal vena cava...

BACKGROUND: Non-recurrent laryngeal nerve (NRLN) is a rare anatomical variant (0.3-6%) that is associated with some arterial abnormalities (absence of the brachiocephalic trunk and presence of a right aberrant subclavian lusorian artery). The availability of a preoperative diagnosis of NRLN may reduce the risk of nerve injuries. Preoperative ultrasonography (US) has been suggested as a reliable diagnostic tool to detect the arterial abnormalities associated with NRLN, but the literature is relatively scarce...

A 10 week old female intact Staffordshire terrier was presented with a total of five congenital cardio-thoracic vascular anomalies consisting of a patent ductus arteriosus (PDA) with an aneurysmic dilation, pulmonic stenosis, persistent right aortic arch, aberrant left subclavian artery and persistent left cranial vena cava. These abnormalities were identified with a combination of echocardiogram and computed tomography angiography (CTA). The abnormalities were associated with esophageal entrapment, regurgitation, and volume overload of the left heart with left atrial and ventricular enlargement...

Kommerell's diverticulum with a right aortic arch and aberrant left subclavian artery is a rare anomaly, and the optimal operative strategy has not yet been established. In particular, the approach to the diverticulum is controversial, with the greatest concern being whether or not to add a right thoracotomy to the median sternotomy for distal anastomosis. We successfully performed total arch replacement through a median sternotomy only, by referring to preoperative computed tomography. We think that if the aneurysm is in a shallow position from the tracheal bifurcation, total arch replacement is possible with a midline incision only...

OBJECTIVES: To determine whether fetuses with an isolated aberrant course of the right subclavian artery (ARSA) have increased risk for chromosomal abnormalities, including trisomy 21 or 22q11 deletion. METHODS: We performed a retrospective chart review of all fetuses with antenatally diagnosed ARSA. Data were collected from fetal anatomic surveys, fetal echocardiograms, noninvasive trisomy 21 screening programs, invasive genetic studies, and neonatal records. RESULTS: Seventy-nine fetuses with ARSA were identified at 20...

A 2-months-old male German shepherd puppy was referred for regurgitation and delayed growth. Radiographic and endoscopic investigations revealed a precardiac megaoesophagus and oesophageal constriction at the level of the heart base. At post-mortem examination, a specific form of persistent right aortic arch characterized by an aberrant left subclavian artery in combination with a ligamentum arteriosum originating at the aberrant left subclavian artery (PRAA-SA-LA) was detected. A complete-type persistent left cranial vena cava (PLCVC) was also observed...

We present a case report of two rare arterial anomalies diagnosed during transradial coronary catheterization-arteria lusoria (aberrant right subclavian artery) and superdominant right coronary artery. Importantly, these anomalies may cause difficulty in performance or interpretation of catheterization procedure, especially in urgent situation and with wide acceptance of transradial approach. To the best of our knowledge, the combination of these anomalies has never been described in the literature.

The random finding of a ruptured Kommerell aneurysm (rKA) is exceptional. We report the case of a 74-year-old man who received an incidental diagnosis of a contained rKA involving an aberrant right subclavian artery after a stroke. He underwent successful hybrid repair with the use of thoracic endovascular aortic repair associated with cervical debranching of the left subclavian artery and vascular plug occlusion of both subclavian artery origins. Whereas no early adverse event was reported, the patient experienced a vertebrobasilar insufficiency once he had recovered, requiring an additional right carotid-to-subclavian bypass...

PURPOSE: Taking into consideration that the aberrant right subclavian artery (ARSA) is the commonest congenital aortic arch anomaly (prevalence 0.16-4.4%), our goal was to investigate its incidence in Greeks, with respect to location, course, and relationship to trachea and esophagus. Gender dimorphism, coexisting neural, and vascular variations were also examined. The clinical impact and embryological background of the variation are discussed. METHODS: Two hundred and sixty-seven (126 male and 141 female) formalin-embalmed Greek cadavers (mean age 59 ± 13 years) were examined...

BACKGROUND: The non-recurrent laryngeal nerve (NRLN) is a rare but potentially serious anomaly that is commonly associated with the aberrant right subclavian artery (ARSA). It is easy to damage during surgical resection of esophageal cancer, leading to severe complications. METHODS: Preoperative enhanced thoracic computed tomography (CT) scans of 2697 patients with esophageal carcinoma treated in our hospital between January 2010 and December 2013 were examined...

Congenital variants and anomalies of the aortic arch are important to recognize as they may be associated with vascular rings, congenital heart disease, and chromosomal abnormalities, and can have important implications for prognosis and management. The purpose of this article is to review cross-sectional imaging techniques used in the evaluation of the aortic arch, describe the embryology and anatomy of the aortic arch system, discuss aortic arch variants and anomalies, and review other malformations of the aortic arch, including interrupted aortic arch, hypoplastic aortic arch, and aortic coarctation...

BACKGROUND: Vascular rings (VRs) are recognized as uncommon but not rare cardiovascular malformations. METHODS: We analyzed data from all patients born in Southern Nevada, who underwent diagnosis and management of VR from 1990 to 2015, RESULTS: From 1990 to 2015, a total of 92 patients were diagnosed prenatally and postnatally. Of the 92 patients, 73 (79%) had right aortic arch and aberrant left subclavian artery (RAA-ALS) with a left ductus arteriosus or ligamentum, 17 (19%) had a double aortic arch (DAA), and 2 (2%) had a pulmonary artery sling...

We herein report a case showing three anatomical variations including the aberrant right subclavian artery (ARSA), the non-recurrent laryngeal nerve (NRLN) and the right thoracic duct in a 59-year-old male cadaver. The right subclavian artery (RSA) arose from the descending aorta next to the left subclavian artery and coursed in between the oesophagus and the thoracic vertebrae. The recurrent laryngeal nerve did not coil around the RSA but directly entered the larynx. Lastly the thoracic duct terminated into the right brachiocephalic vein...

BACKGROUND: Anomalous left brachiocephalic vein (ALBCV) is a rare and less known systemic venous anomaly. Infrequently, this vein takes an abnormal course and passes to the right behind or beneath the aortic arch to create the superior vena cava (SVC). Its incidence was reported much higher in patients with congenital heart disease (CHD) especially in conotruncal and aortic arch anomalies. It could be misdiagnosed with normal or abnormal mediastinal structures. It also could make complication during surgeries or invasive strategies...

OBJECTIVES: Complete vascular rings are rare and cause tracheoesophageal compression. Following surgical division, some patients have persisting tracheomalacia. We aim to assess the long-term outcomes of complete vascular ring division. METHODS: All patients (n = 132) who underwent surgical division of a complete vascular ring between 1978 and 2014 were identified from the hospital database and retrospectively reviewed. RESULTS: Complete vascular rings consisted of a double aortic arch (n = 80), right aortic arch with an aberrant subclavian artery and left ligamentum arteriosum (n = 50), right aortic arch with mirror image branching and left ligamentum arteriosum (n = 1), and a left aortic arch with right descending aorta and right ligamentum arteriosum (n = 1)...

A 78-year-old man with a Kommerell diverticulum and aberrant right subclavian artery was admitted for thoracic pain and severe malnutrition due to esophageal compression. We performed an atypical surgical procedure including extra-anatomical debranching and direct aortic repair, trying to avoid deep hypothermic circulatory arrest and shorten the cardiopulmonary bypass time.
