The right vertebral artery (VA) rarely arises from the right common carotid artery (CCA); however, the majority of anomalous right VAs are seen in combination with an aberrant right subclavian artery (SA). Independent (or isolated) right VA of the right CCA origin is extremely rare, with only a few cases reported previously. We herein report an additional case diagnosed incidentally using computed tomography angiography. This patient had a left VA arising from the aortic arch between the origins of the left CCA and left SA. The bilateral VAs took an anterior course and entered the C3 transverse foramina, at an extremely high level.

Aberrant right subclavian artery (ARSA) is a relatively rare congenital anomaly of the aortic arch. A 74-year-old woman was referred to our Cardiac Surgery Department for chest pain. Angio-CT scan showed an acute aortic dissection and revealed an ARSA routed behind the trachea. We performed supra-coronary ascending aorta and total arch replacement with Frozen Elephant Trunk (FET) technique. The ARSA was then termino-terminal anastomosed to one branch of the Thoraflex arch graft. Postoperative CT-scan indicated a successful reconstruction of the aortic arch, proving the open stent-grafting technique as a useful and effective approach for aortic disease with ARSA.

Highlights • Blunt thoracic aortic injuries are life threatening and require urgent intervention. • Rare presentation of a blunt thoracic aortic injury in a patient with an aberrant right subclavian artery off the aortic arch distal to the takeoff of the left subclavian artery. • An aberrant right subclavian artery originating from the aortic arch, distal to the left subclavian artery is an anatomic variant that adds significant complexity to TEVAR., Introduction Blunt thoracic aortic injuries (BTAIs) are an uncommon traumatic injury that if not treated promptly, can result in death. We present the case of a BTAI with aberrant aortic anatomy. Presentation of case A 60-year-old female was involved in a motor vehicle crash where she suffered significant polytrauma including a BTAI. She was also found to have an aberrant right subclavian artery originating from the aortic arch. Thoracic Endovascular Aortic Repair (TEVAR) with a right common carotid artery to right subclavian artery bypass was accomplished. She required three more vascular surgical interventions, two for persistent type II endoleak and the third for left upper extremity acute limb ischemia. She had a 2-month hospital course for her devastating injuries and was eventually discharged home. A follow-up CT angiogram showed a stable thoracic aortic arch stent. Discussion BTAIs are uncommon in the trauma population. In our patient who had an aberrant right subclavian artery, further procedures were required in the form of a right common carotid artery to right subclavian artery bypass and embolizations to resolve endoleaks. Conclusion Blunt thoracic aortic injuries are life threatening and require urgent intervention. TEVAR is associated with better outcomes. An aberrant right subclavian artery originating from the aortic arch, distal to the left subclavian artery is an anatomic variant that adds significant complexity to TEVAR. TEVAR is still an option for repair of blunt thoracic aortic injuries despite anatomic variations as open repair still carries an increased risk of morbidity and mortality.

An aberrant right subclavian artery usually arises from the aortic arch just distal to the left subclavian artery and crosses behind the esophagus on its way to the right axillary artery. Several reconstructive techniques of this artery in aortic surgery have been reported but mostly resulted in troublesome procedures. Here, we describe an alternative strategy presenting the occlusion of the aberrant right subclavian artery through the right pleural approach followed via extraanatomical axillary artery bypass. This surgical approach might be a simple and safe option for the aberrant right subclavian artery.

An aberrant right subclavian artery (ARSA) is one of the famous anatomical abnormalities with a prevalence of 0.16-4.4%. In esophagectomy, anatomical abnormalities of the ARSA could cause complications with some surgical procedures. An 85-year old man was referred to our department for esophageal adenocarcinoma that was at a slightly high position for esophagectomy with the abdominal approach. However, he had a significant past medical history. This risk factor made it difficult to perform thoracoscopic esophagectomy. He underwent mediastinoscopic esophagectomy (ME) with the left cervical and laparoscopic approach. The ARSA presented no difficulties with the ME surgical technique including the dissection of the left recurrent laryngeal nerve lymph node. Although this patient had a respiratory dysfunction and some difficulties in a prone position, ME enabled a safe esophagectomy with lymph node dissection.

Dysphagia Lusoria is a condition when aberrant right subclavian artery (ARSA) causes esophageal compression. We report 2 cases of Dysphagia Lusoria treated by hybrid endovascular technique which included subclavian to carotid transposition and embolization of origin of ARSA. By using this technique, we avoided the need for thoracotomy. Both patients had complete symptom relief without any surgery related complication.

Background The lesions of aberrant right subclavian artery, Kommerell’s diverticulum and type A aortic intramural hematoma are rare, and we usually treat them with open surgery. In some cases patients have increased risk to undergo surgery, the experiences of endovascular or medical treatment are limited. Case presentation Here we reported a case of a 53-year-old man with these three entities present with chest and back ache and attempted a novel approach, thoracic endovascular aortic repair, in the absence of surgical treatment. The patient lived over 5 years and this case provides initial experience and lesson about the endovascular and medical management of the uncommon and dangerous disease- type A aortic intramural hematoma with aortic congenital malformation. Conclusion Thoracic endovascular aortic repair with medical treatment may be a potential alternative approach for type A aortic intramural hematoma.

Highlights • Aberrant right subclavian artery (ARSA) is a rare cause of dysphagia. • Surgical intervention is the mainstem of therapy. • Endoscopic dilation is a suitable treatment alternative in non-surgical candidates., Introduction The aberrant right subclavian artery (ARSA) is a rare cause of dysphagia. Surgical intervention has remained the mainstem of therapy, accompanied with certain morbidities and mortalities. Although rarely reported in literature, endoscopic dilation may be considered a suitable treatment alternative in patients who are not a surgical candidate or do not consent for surgery. We report a case suffering from dysphagia and diagnosed with ARSA treated by endoscopic dilation. Presentation of case A 52-year-old male presented to our clinic in 2015 with dysphagia. Chest Computed Tomography scan confirmed the diagnosis of ARSA. He first underwent esophagogastroduodenoscopy (EGD) with staged dilation of the stricture, making him free of his symptoms for an approximate 2.5 years. Upon recurrence of symptoms in 2018, he underwent repeat endoscopic dilation, which again completely resolved the symptom with an excellent peri-operative and post-operative course. Conclusion Endoscopic dilation of the esophageal stricture in patients with ARSA is a safe alternative to surgery in patients who are unable or unwilling to undergo surgery. It provides relief for a relatively long time and can be safely repeated multiple times upon recurrence.

Highlights • Aberrant Right Subclavian artery is also known as Arteria Lusoria. • Rarer congenital malformations of the aortic arch. • Causes compression of the trachea or esophagus causing dysphagia. • May occur simultaneously with an ostium secundum atrial septal defect. • Both conditions repaired simultaneously via Median Sternotomy., Introduction Aberrant right subclavian artery, also known as arteria lusoria, is one of the rarer congenital vascular malformations of the left sided aortic arch which arises distal to the left subclavian artery, following a retroesophageal course to the right side causing compression of the trachea or esophagus and resulting in a variety of symptoms most commonly dysphagia. Presentation of case We report a case of a two and a half year old child who was diagnosed as having as having an aberrant right subclavian artery with an ostium secundum atrial septal defect and underwent simultaneous repair of both conditions via a median sternotomy. Discussion Aberrant right subclavian artery (ARSA) has a prevalence of 1.8 % and most commonly presents in fourth or fifth decade of life. Various surgical approaches have been described to repair this anomaly over the past years, each with its own limitations and complications. However, the median sternotomy approach provides adequate exposure during division and re-implantation of the vessel and simultaneously allows repair of any intra-cardiac defect. Conclusion We believe that the best exposure for the correction of aberrant right subclavian artery is via a median sternotomy, especially in pediatric patients associated with other cardiac anomalies.

Arterioenteric or arteriotracheal fistula is a known complication of an aberrant right subclavian artery (ARSA) and is often associated with prolonged nasogastric or endotracheal intubation or oesophageal stenting. Fistula formation from the ARSA can present unexpectedly with rapid exsanguination with massive haemoptysis or haematemesis, and unless promptly recognised and treated is rapidly fatal. We present a novel endovascular method for treating a fistula between the oesophagus, trachea and an ARSA in an unstable patient following oesophageal stent removal, utilising a covered iliac limb stent, eliminating the need for an open surgical approach.

Background Aberrant right subclavian artery (ARSA) with associated Kommerell diverticulum (KD) is a rare congenital aortic disease. KD patients have a high risk of rupture, dissection, and compression of adjacent structures. Although several treatment options have been proposed (traditional surgery, hybrid operation, and endovascular intervention), a consensus regarding optimal surgical management has not yet been established. Case presentation A case of successful hybrid repair of distal aortic arch dissection aneurysm by dissecting KD and ARSA with debranching of right and left common carotid arteries, left subclavian artery, and stent grafting was presented. Conclusions The hybrid operation is suitable for elderly patients or those with high risks. Along with intervention, the hybrid operation needs to be developed as a minimally invasive method.

Background: Coarctation of the aorta (CoA) can either present alone as an isolated condition or in association with other aortic arch or cardiac anomalies. One percent of patients with CoA have concomitant an aberrant right subclavian artery (ARSA). Purpose: We report the case of a 35-year-old woman with uncontrolled hypertension who was found to have CoA and ARSA. Results: The patient was treated successfully using a hybrid procedure comprising ARSA ligation and subclavian to carotid transposition, followed by thoracic endovascular aortic repair. Conclusions: Patients with CoA should be carefully studied, considering the possible coexistence of other congenital aortic arch defects, such as ARSA. Hybrid repair is a safe and effective approach for this condition.

Diverticulum of Kommerell is a congenital anomaly in the development of the primitive embryonic aortic vasculature resulting in either an aberrant left subclavian artery (ALSA) from a right-sided aortic arch (RSAA) or an aberrant right subclavian artery (ARSA) from a left-sided aortic arch (LSAA). Kommerell’s diverticulum (KD), is extremely rare in the general population having prevalence of 0.7–2.0 %. KD with true aneurysmal dilatation like any vascular lesion of the thoracic aorta weakens the vasculature and increases the risk of aortic rupture. Timely surgical intervention is of paramount importance in most of these cases. Variable clinical presentations in patients with KD are either a result of compression of some mediastinal organs or strangulation by the vascular ring from the aberrant subclavian artery (ASA). We report a case of a 39 years old Chinese female with a rare co-existence of a huge KD with a microaneurysm, an aberrant right subclavian artery (ARSA), and ventricular septal defect (VSD). She underwent a successful operation and all her pre-surgical symptoms disappeared.

An aberrant right subclavian artery (ARSA) is a rare arterial anomaly. Although a few cases of total endovascular repair for the ARSA aneurysm have been previously reported, anatomical limitations and the possibility of endoleaks remained. In this case, we created 4 holes on the stent graft for each cervical branch, with reference to the preoperative computed tomography findings. This approach might enable us to repair all types of thoracic aortic aneurysms with ARSA with each anatomical feature.

We report an emergent complex hybrid repair of a type A intramural hematoma with a tear of the aortic arch at the site of Kommerell's diverticulum and an aberrant right subclavian artery. We identified a type IA endoleak intraoperatively, which was managed immediately with proximal extension. Performing this operation in the hybrid operating room facilitated optimal surgical management.

Background An anomalous origin of the right vertebral artery (VA) from the right internal carotid artery (ICA) occurs only rarely. Case Description A 70-year-old man underwent carotid artery stenting for right internal carotid artery stenosis. In this patient, the right VA arose from the right ICA associated with an aberrant right subclavian artery. Conclusion Embryologically, failure of involution of 1 of the first 6 intersegmental arteries causes various abnormal origins of the VA. The embryonic development of this anomaly is also reviewed.

Aberrant right subclavian artery (ARSA) with associated Kommerell diverticulum (KD) is a rare congenital aortic arch anomaly. Patients with KD have a high risk of rupture, dissection, compression of adjacent structures, as well as distal embolization symptoms. Several treatment options have been proposed (surgical, hybrid, endovascular), however, a consensus regarding optimal surgical management has not been established yet. We present a successful single-stage hybrid repair of distal aortic arch dissection aneurysm with dissecting KD and ARSA with debranching of innominate and left common carotid artery, bilateral carotid-subclavian bypass, and stent grafting.

Purpose of review To address the incidental versus pathogenic nature of dysphagia lusoria and to provide a review of the cause, clinical presentation, diagnosis, and treatment of this condition with respect to recent literature. Recent findings Case reports comprise the majority of recent literature concerning dysphagia lusoria. Many patients with an aberrant right subclavian artery (ARSA) have additional coexisting vascular anomalies. While most individuals present around age 50, some present as children and neonates. Of note, this population may present with dysphagia as opposed to respiratory findings alone, as previously described. In the diagnostic workup, most patients receive a battery of radiologic tests, which may not be necessary. Significantly, dietary modifications and medical management alone may resolve symptoms. Nonetheless, a wide range of operative techniques are available for the treatment of dysphagia lusoria. Summary Clinicians should have a higher suspicion for dysphagia lusoria in patients with known vascular, heart, or chromosomal anomalies. Diagnosis should begin with a barium esophagram followed by a computed tomography angiogram or magnetic resonance angiogram. Avoid unnecessary studies. In many cases, an ARSA may be an incidental finding with comorbid gastroesophageal reflux disease or another medical condition responsible for the symptoms. Medical versus surgical management should be considered on a case-by-case basis.

Aortic atresia with interrupted aortic arch (IAA) is an exceptional condition. In absence of associated lesion, the flow to the brain and the retrograde flow to the coronary arteries can only come from vessels on the descending aorta. This flow needs to be large enough to supply the brain and the myocardium. The only IAA type compatible with survival is type C where the flow from descending aorta could be insured by the left carotid and the left vertebral artery, branch of the left subclavian artery. Only one such a case was described in the literature. All the other surviving cases had an associated lesion including: a double aortic arch, an aorto-pulmonary window (AP window), an aberrant right subclavian artery or a bilateral patent ductus arteriosus (PDA). We report a case of aortic atresia with IAA type B associated with a double aortic arch that underwent a successful bi-ventricular one-stage neonatal Norwood-Rastelli repair and is doing well after 18 months.

Objectives We present a case in which a 44-year-old female smoker with a complex medical and surgical history presented with acute upper limb ischemia. Methods The patient was diagnosed with thoracic outlet syndrome causing symptomatic thrombosis of an aberrant right subclavian artery associated with diverticulum of Kommerell. The patient had history of extensive surgeries and radiation in the right chest with fibrotic changes, so surgical dissection in the area was associated with significant risk of nerve injury. Therefore, revascularization of the arm was performed via carotid to brachial artery bypass with reversed saphenous vein and the thoracic outlet was decompressed with segmental clavicular resection. Results Patient has been symptom free for 3 years with patent bypass. Conclusions This case demonstrates a unique presentation of distal thrombosis of a symptomatic aberrant right subclavian artery related to thoracic outlet syndrome. The combined claviculectomy–vein bypass is a safe and efficacious surgical approach that provides durable relief.

Aberrant right subclavian is a rare anomaly presenting in 0.3–3.0% of the population. Kommerell’s diverticulum is an aneurysm associated with this phenomen; data relating to its incidence is sparse. Currently there are no well-established guidelines for the treatment of Kommerell’s diverticulum, limitation being the rare occurrence of disease and heterogenous population with disease presentation. This case report illustrates a novel approach to the repair of a symptomatic Kommerrel’s diverticulum with severe coronary disease. Management should be tailored on a case by case basis to the individual patient.

Purpose: Aberrant right subclavian artery (ARSA) associated with Kommerell’s diverticulum (KD) is a common congenital arch anomaly. It can be complicated by type B aortic dissection (TBAD) or aneurysmal formation at its ostium. Recently, hybrid repair with thoracic endovascular aortic repair (TEVAR) has appeared to be more favorable. Due to the normal anatomic proximity of the ARSA to the left subclavian artery (LSA) orifice in KD, coverage of the bilateral subclavian arteries (SCAs) to obtain an adequate proximal landing zone (PLZ) is usually required, and double cervicotomy for SCA revascularization potentially increases the risk of complications. Technique: This technique was demonstrated on a 50-year-old man presenting with progressive aneurysmal formation of KD with ARSA after chronic TBAD. A 3-step technique, namely left cervical debranching with a left common carotid artery to LSA bypass graft, TEVAR, and an LSA-to-ARSA endovascular debranching with a self-expanding covered stent by a through-and-through wire from the right brachial artery to the bypass graft, was performed in a 1-stage repair to cover the primary tear of TBAD and preserve the bilateral SCAs. The postoperative course was uneventful. Conclusion: This technique can prevent complications from double cervicotomy and achieve an adequate PLZ with preservation of the bilateral SCAs for TEVAR.

Typical branching pattern of the left-sided aortic arch consists of the brachiocephalic trunk (BCT), the left common carotid artery (LCCA) and the left subclavian artery (LSA). Variant patterns have been associated with a broad spectrum of pathologies. The meticulous knowledge of potential aortic arch variants is of utmost importance to radiologists, interventional cardiologists, vascular and thoracic surgeons. The current systematic review collects all aortic arch branching patterns and their frequency as published by various cadaveric studies, calculates prevalence taking into account the gender and the different people background, as well. All extracted variant patterns are classified into types and subtypes according to the number of emerging (major and minor) branches (1, 2, 3, 4 and 5) and to the prevalence they appear. In cases of similar prevalence, total cases were taken into consideration; otherwise the variants were classified under the title “other rare variants”. A systematic online search of PubMed and Google books databases was performed only in cadaveric studies. Twenty studies with typical (78% prevalence) and variable (22%) branching patterns were included. Types 3b, 2b, 4b, 1b and 5b had a prevalence of 81%, of 13%, of 5%, 0% and of 0%, respectively. Common variants were the brachiocephalico-carotid trunk (BCCT, 49% prevalence), the aberrant left vertebral artery (LVA, 41%) and the aberrant right subclavian artery (ARSA, 8%). LVA of aortic origin was detected in 32%, the bicarotid trunk (biCT) in 5% and the bi-BCT trunk in 3%. Thyroidea ima artery, a minor branch emerging from the aortic arch was found in 2%. Coexisted variants were detected in 4% (ARSA with a distinct RCCA and LCCA origin), in 3% (BCCT with a LVA of aortic origin), in 2% (ARSA with a biCT and a vertebrosubclavian trunk). No significant gender or ethnic differences exist among the 5 branching types. The proposed classification scheme aims to become a valuable and easy to use tool in the hands of all physicians involved in diagnosis and treatment of aortic arch pathology. It could be also useful in anatomical education, as well.

We hereby present a rare variant course of left brachiocephalic vein coexisting with an aberrant right subclavian artery in a patient with a ventricular septal defect with pulmonary atresia. This case highlights the importance of CT angiography in diagnosing associated aortic arch and systemic venous anomalies in complex congenital heart diseases.
