Lusory dysphagia: Unusual cause of intermittent dysphagia. Int J Surg Case Rep 2024; 119:109676. [PMID: 38688156 PMCID: PMC11067468 DOI: 10.1016/j.ijscr.2024.109676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 04/10/2024] [Accepted: 04/19/2024] [Indexed: 05/02/2024] Open
Abstract
INTRODUCTION AND IMPORTANCE Lusory dysphagia (LD) is a rare disorder resulting from extrinsic vascular compression of the esophagus, is often associated with an aberrant right subclavian artery (ARSA). LD is characterized by abnormal development of the right fourth aortic arch during embryonic stages, leading to posterior coursing of the artery in 80 % of cases. Predominantly presenting as dysphagia, LD can occasionally manifest with laryngeal stridor or dyspnea, yet it often remains asymptomatic and incidentally discovered. CASE PRESENTATION We present a case of LD in a 24-year-old male with Down syndrome, experiencing prolonged dysphagia and recurrent aspiration episodes. Emergency upper gastrointestinal endoscopy revealed food impactation beyond the upper esophageal sphincter, and subsequent imaging studies confirmed an aberrant right subclavian artery causing extrinsic compression. DISCUSSION LD is a rare condition. It is a challenging diagnosis often necessitating a combination of endoscopy, contrasted imaging and angiography. Treatment strategies vary, with conservative approaches for mild symptoms involving dietary modifications, and surgical intervention considered for persistent or severe cases. CONCLUSION Recognizing LD in the context of long-standing dysphagia is crucial for accurate diagnosis and appropriate management. Further research is needed to establish standardized diagnostic and therapeutic guidelines for this uncommon condition.

Characterization and surgical management of aberrant subclavian arteries. J Vasc Surg 2023; 77:1006-1015. [PMID: 36565775 DOI: 10.1016/j.jvs.2022.12.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 12/14/2022] [Accepted: 12/15/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVE Aberrant subclavian arteries (aSCAs), with or without aortic pathology, are uncommon. The purpose of the present study was to review our experience with the surgical management of aSCA. METHODS We performed a retrospective review of patients who had undergone surgery for an aSCA between 1996 and 2020. Symptomatic and asymptomatic patients were included. The primary end points were ≤30-day and late mortality. The secondary end points were ≤30-day complications, graft patency, and reinterventions. RESULTS A total of 46 symptomatic and 3 asymptomatic patients with aSCA had undergone surgery (31 females [62%]; median age, 45 years). An aberrant right subclavian artery was present in 38 (78%) and an aberrant left subclavian artery in 11 patients (22%). Of the 49 patients, 41 (84%) had had a Kommerell diverticulum (KD) and 11 (22%) had had a concomitant distal arch or proximal descending thoracic aortic aneurysm. Symptoms included dysphagia (56%), dyspnea (27%), odynophagia (20%), and upper extremity exertional fatigue (16%). Five patients (10%) had required emergency surgery. The aSCA had been treated by transposition in 32, a carotid to subclavian bypass in 11, and an ascending aorta to subclavian bypass in 6. The KD was treated by resection and oversewing in 19 patients (39%). Fifteen patients (31%) had required distal arch or proximal descending thoracic aortic replacement for concomitant aortic disease and/or KD treatment. Thoracic endovascular aortic repair was used to exclude the KD in six patients (12%). Seven patients (14%) had undergone only bypass or transposition. The 30-day complications included one death from pulseless electrical activity arrest secondary to massive pulmonary embolism. The 30-day major complications (14%) included acute respiratory failure in three, early mortality in one, stroke in one, non-ST-elevation myocardial infarction in one, and temporary dialysis in one patient. The other complications included chylothorax/lymphocele (n = 5; 10%), acute kidney injury (n = 2; 4%), pneumonia (n = 2; 4%), wound infection (n = 2; 4%), atrial fibrillation (n = 2; 4%), Horner syndrome (n = 2; 4%), lower extremity acute limb ischemia (n = 1; 2%), and left recurrent laryngeal nerve injury (n = 1; 2%). At a median follow-up of 53 months (range, 1-230 months), 40 patients (82%) had had complete symptom relief and 9 (18%) had experienced improvement. Six patients had died at a median of 157 months; the deaths were not procedure or aortic related. The primary patency was 98%. Reintervention at ≤30 days had been required for two patients (4%) for ligation of lymphatic vessels and bilateral lower extremity fasciotomy after proximal descending thoracic aorta replacement. One patient had required late explantation of an infected and occluded carotid to subclavian bypass graft, which was treated by cryopreserved allograft replacement. CONCLUSIONS Surgical treatment of the aSCA can be accomplished with low major morbidity and mortality with excellent primary patency and symptom relief.

Abstract
Isolation of the left subclavian artery is a rare anomaly associated with right aortic arch. We report a case in which this subclavian artery was supplying the pulmonary circulation in a patient with tetralogy of Fallot (TOF) which effectively acted as a natural systemic to pulmonary artery shunt. The patient had good room air saturation and no features of vertebrobasilar insufficiency or left upper limb ischemia. She underwent a total correction of TOF and ligation of the aberrant left subclavian artery.

A systematic review of open, hybrid, and endovascular repair of aberrant subclavian artery and Kommerell's diverticulum treatment. J Vasc Surg 2023; 77:642-649.e4. [PMID: 35850164 DOI: 10.1016/j.jvs.2022.07.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Revised: 06/16/2022] [Accepted: 07/07/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND Aberrant subclavian artery (AScA) with or without associated Kommerell's diverticulum (KD) is the most frequently encountered anomaly of the aortic arch, it may be life threatening, especially when associated with aneurysmal degeneration. The best management is still debated and depends on many clinical and anatomical factors. A systematic review was conducted to assess the current evidence on the treatment options and their efficacy and safety for AscA and KD repairs. METHODS A literature search in PubMed and Cochrane Library was performed, and articles that were published from January 1947 to August 2021 reporting on AscA and KD management were identified. Multicenter studies, single-center series, and case series with three or more patients were considered eligible in the present review. A comparison of outcomes of patients who underwent open surgery (OS), a hybrid approach (HA), and total endovascular repair (ER) (ie, 30-day mortality and stroke were analyzed when available and compared among the three groups (P < .05; Benjamini and Hochberg-adjusted P < .05; Bonferroni-adjusted P < .05). Titles, abstracts, and full texts were evaluated by two authors independently. Primary outcomes included survival rate, perioperative stroke, arm ischemia, and spinal cord ischemia. Endoleak, in the case of HA and ER, and reintervention rates were considered outcomes. RESULTS Three hundred thirty-one articles were initially evaluated and 30 studies, totaling 426 patients treated for AScA with 324 KD, were included. Of the 426 patients, 241 were male (56.5%), and the mean patient age was 57.9 ± 12.0 years. The approach was OS in 228 patients, HA in 147 patients, and ER in 51. Dysphagia was the most common presentation in 133 cases. Aortic rupture was observed in 16 of the 426 patients (3.8%), including 14 AScA/KD (3.3%) aneurysm rupture. KD maximum diameter varied widely from 12.6 to 63.6 mm. The overall 30-day mortality was 20 (4.7%) (OS group 8/228 [3.5%]; HA group 10/147 [6.8%]; ER 2/51 [3.9%]; P = NS). The overall stroke rate was 4.9% (21/426) (OS group 10/228 [4.4%]; HA group 6/147 [4.1%]; ER group 5/51 [9.8%]; P = NS), including nine transient and nondisabling neurological deficits. Overall secondary procedures for complications were reported in 36 of the 426 cases (8.4%), mostly owing to endoleak. Follow-up varied from 13 to 74 months. CONCLUSIONS This systematic review assessed the current outcomes of the three types of therapeutic management for AScA and KD and demonstrated that they are all relatively safe and effective, providing satisfactory early and midterm outcomes. Long-term outcomes are warranted, especially for total ERs since the long-term durability of stent grafts remains unknown.

Contemporary outcomes after treatment of aberrant subclavian artery and Kommerell's diverticulum. J Vasc Surg 2023; 77:1339-1348.e6. [PMID: 36657501 DOI: 10.1016/j.jvs.2023.01.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 01/05/2023] [Accepted: 01/06/2023] [Indexed: 01/18/2023]
Abstract
OBJECTIVE Aberrant subclavian artery (ASA) and Kommerell's diverticulum (KD) are rare vascular anomalies that may be associated with lifestyle-limiting and life-threatening complications. The aim of this study is to report contemporary outcomes after invasive treatment of ASA/KD using a large international dataset. METHODS Patients who underwent treatment for ASA/KD (2000-2020) were identified through the Vascular Low Frequency Disease Consortium, a multi-institutional collaboration to investigate uncommon vascular disorders. We report the early and mid-term clinical outcomes including stroke and mortality, technical success, and other operative outcomes including reintervention rates, patency, and endoleak. RESULTS Overall, 285 patients were identified during the study period. The mean patient age was 57 years; 47% were female and 68% presented with symptoms. A right-sided arch was present in 23%. The mean KD diameter was 47.4 mm (range, 13.0-108.0 mm). The most common indication for treatment was symptoms (59%), followed by aneurysm size (38%). The most common symptom reported was dysphagia (44%). A ruptured KD was treated in 4.2% of cases, with a mean diameter of 43.9 mm (range, 18.0-100.0 mm). An open procedure was performed in 101 cases (36%); the most common approach was ASA ligation with subclavian transposition. An endovascular or hybrid approach was performed in 184 patients (64%); the most common approach was thoracic endograft and carotid-subclavian bypass. A staged operative strategy was employed more often than single setting repair (55% vs 45%). Compared with endovascular or hybrid approach, those in the open procedure group were more likely to be younger (49 years vs 61 years; P < .0001), female (64% vs 36%; P < .0001), and symptomatic (85% vs 59%; P < .0001). Complete or partial symptomatic relief at 1 year after intervention was 82.6%. There was no association between modality of treatment and symptom relief (open 87.2% vs endovascular or hybrid approach 78.9%; P = .13). After the intervention, 11 subclavian occlusions (4.5%) occurred; 3 were successfully thrombectomized resulting in a primary and secondary patency of 95% and 96%, respectively, at a median follow-up of 39 months. Among the 33 reinterventions (12%), the majority were performed for endoleak (36%), and more reinterventions occurred in the endovascular or hybrid approach than open procedure group (15% vs 6%; P = .02). The overall survival rate was 87.3% at a median follow-up of 41 months. The 30-day stroke and death rates were 4.2% and 4.9%, respectively. Urgent or emergent presentation was independently associated with increased risk of 30-day mortality (odds ratio [OR], 19.8; 95% confidence interval [CI], 3.3-116.6), overall mortality (OR, 3.6; 95% CI, 1.2-11.2) and intraoperative complications (OR, 8.3; 95% CI, 2.8-25.1). Females had a higher risk of reintervention (OR, 2.6; 95% CI, 1.0-6.5). At an aneurysm size of 44.4 mm, receiver operator characteristic curve analysis suggested that 60% of patients would have symptoms. CONCLUSIONS Treatment of ASA/KD can be performed safely with low rates of mortality, stroke and reintervention and high rates of symptomatic relief, regardless of the repair strategy. Symptomatic and urgent operations were associated with worse outcomes in general, and female gender was associated with a higher likelihood of reintervention. Given the worse overall outcomes when symptomatic and the inherent risk of rupture, consideration of repair at 40 mm is reasonable in most patients. ASA/KD can be repaired in asymptomatic patients with excellent outcomes and young healthy patients may be considered better candidates for open approaches versus endovascular or hybrid modalities, given the lower likelihood of reintervention and lower early mortality rate.

Abstract
Purpose of Review Vascular rings are congenital malformations resulting from abnormal development of the great vessels, with the consequent encircling and compression of the trachea, esophagus, or both. We conducted a review of the current literature to identify the different management strategies that can be implemented based on the prognosis of each of these anomalies. Recent Findings Although most vascular rings occur in isolation, they can also be associated with other congenital cardiac and/or respiratory diseases; therefore, thorough investigation is necessary before definitive surgical repair. Clinical presentation varies from asymptomatic to severe, with both respiratory and digestive symptoms. Although early surgical results are acceptable, the long-term outcome is variable; therefore, there is still controversy regarding the appropriate timing of treatment. This is especially true with regard to the Kommerell diverticulum (KD) and in patients without symptoms at the time of initial surgical evaluation. Summary As more sophisticated diagnostic tools have become available and more studies on adults affected by this condition have been published, understanding of this condition and its additional clinical implications has grown and appears to be tilting management toward earlier intervention.

Iatrogenic aortic dissection during right transradial intervention in a patient with aberrant right subclavian artery: A case report. World J Clin Cases 2022; 10:9897-9903. [PMID: 36186178 PMCID: PMC9516934 DOI: 10.12998/wjcc.v10.i27.9897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 06/25/2022] [Accepted: 08/17/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Aberrant right subclavian artery (ARSA) is the most common congenital anomaly of the aortic arch. When patients having such anomalies receive transradial intervention (TRI), aortic dissection (AD) may occur. Herein, we discuss a case of iatrogenic type B AD occurring during right TRI in an ARSA patient, that was later salvaged by percutaneous angioplasty.
CASE SUMMARY A 73-year-old man presented to our hospital with intermittent chest pain. Coronary computed tomography (CT) angiography revealed significant stenosis in the left anterior descending artery. Diagnostic coronary angiography was performed via the right radial artery without difficulty. However, we were unable to advance the guiding catheter past the ostium of the right subclavian artery to the aortic arch for percutaneous coronary intervention, while the guidewire tended to go down the descending aorta. The patient suddenly complained of chest and back pain. Emergent CT aortography revealed type B AD propagating to the left renal artery (RA) with preserved renal perfusion. However, after 2 d, the patient suddenly complained of right lower limb pain where the femoral pulse was suddenly undetectable. Follow-up CT indicated further progression of dissection to the right external iliac artery (EIA) and left RA with limited flow. We performed percutaneous angioplasty of the right EIA and left RA without complications. Follow-up CT aortography at 8 mo showed optimal results.
CONCLUSION A caution is required during right TRI in ARSA to avoid AD. Percutaneous angioplasty can be a treatment option.

Abstract
We report a rare case of vascular ring due to a left cervical circumflex aortic arch with aberrant right subclavian artery arising from a Kommerell diverticulum. This is a very rare case of vascular ring in a newborn with stridor and stenosis of the left pulmonary artery. A cardiac catheterization and an angio-computed tomography scan were helpful to clarify the diagnosis. The surgical correction was performed with division of the arterial duct, reimplantation of the right subclavian artery, aortic and tracheal suspension, and pulmonary arterial plasty. The patient was asymptomatic at discharge and 1-year follow-up.

Abstract
The aberrant right subclavian artery (ARSA, arteria lusoria) is the most common intrathoracic vascular anomaly, affecting up to 2% of the population. However, aneurysms of congenital anomalies are extremely unusual and often present with dysphagia, dysphonia, or dyspnea due to compression of the surrounding structures. We report a case of an asymptomatic 57-year-old male with chronic kidney disease who was incidentally found to have a large aneurysm of the ARSA on preoperative computed tomography for laparoscopic nephrectomy. Surgery is unequivocally warranted as these aneurysms are associated with a high risk of complications, including thrombosis, embolism, and rupture. We debranched the ARSA, followed by anastomosis to the right carotid artery through a right neck incision. Subsequently, aneurysmal resection was performed through left thoracotomy. The patient had an uneventful postoperative recovery and was asymptomatic during the follow-up.

Abstract
BACKGROUND/PURPOSE Kommerell diverticulum (KD) in children with right aortic arch and aberrant left subclavian artery can be treated surgically via left subclavian artery (LSCA) translocation or aortopexy. These procedures remain controversial. We compared the outcomes of both procedures. METHODS This retrospective study included 48 patients who underwent LSCA translocation (n = 26) or aortopexy (n = 22). Lateral thoracotomy and sternotomy were performed in 38 and 10 patients with severe intracardiac malformations, respectively. RESULTS The median age of the aortopexy group was 10 months, median follow-up was 14 months, and mean length of hospitalization was 11.41 ± 6.8 days. The median age of the LSCA translocation group was 12 months, median follow-up was 22 months, and mean length of hospitalization was 14.96 ± 7.74 days. Two patients (LSCA translocation group) required secondary intubations and none suffered from recurrent laryngeal nerve injury or complications related to LSCA translocation. Breathing and swallowing symptoms were relieved in all patients. No additional thoracotomies due to respiratory symptoms were required. CONCLUSIONS These two procedures relieve the pressure on the trachea and esophagus with similar short-term outcomes. The long-term outcomes are unknown. LSCA translocation may be the best strategy to prevent symptom recurrence and late complications in these patients. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVES Kommerell diverticulum (KD) is a rare congenital vascular anomaly often associated with an aberrant subclavian artery (ASCA). Definitive indications for intervention remain unclear. We present open and endovascular (EV) operative outcomes in a large contemporary series and propose a management algorithm. METHODS Between 2004 and 2020, 224 patients presented with ASCA and associated KD to our institution. Of the 43 (19.2%) patients who underwent operative repair, 31 (72.1%) had open surgical (OS) repair via thoracotomy and 12 (27.9%) had EV repair. Univariable and bivariable statistical analyses were conducted stratified by approach. The median follow-up time was 5.4 years (IQR, 2.9-9.7). RESULTS Patients in EV group were older (68 years vs 47 years, P < 0.001) and had larger aneurysms (base diameter 3.2 cm vs 21.5 cm, P = 0.007). All patients with dysphagia lusoria were treated with open surgery (n = 20). Asymptomatic patients with incidentally detected KD (50% vs 16.1%), those with chest or back pain (50% vs 19.4%) and patients who presented with an aortic emergency (25% vs 6.5%) were more likely to be treated endovascularly (P = 0.001). Carotid-to-subclavian bypass was used in 38 (88.4%) patients. There were no operative mortalities. In-hospital mortality was similar between groups (3.2% vs 16.7%, P = 0.121). Mid-term mortality was higher in the EV group [4 (33.8%) vs 0, P < 0.001]. There were 2 (15.4%) postoperative strokes in the EV group. There were no statistically significant differences in other postoperative complications or hospital length of stay between groups. CONCLUSIONS KD can be managed using open or EV approaches with low morbidity and mortality. Treatment strategy should depend on clinical presentation and patient factors.

Abstract
Congenital Aortic arch malformations are rare in adults. Often they present with hypertension or tracheoesophageal compression. The involved anatomy is dependent on the sidedness of the aortic arch and the variable development of the primitive pharyngeal arches. Sternotomy and thoracotomy are usually required for surgical repair, while need for circulatory arrest is not uncommon. With caution and adequate planning, surgery can be carried out with satisfactory results.

Outcomes of Surgical Repair of Vascular Rings and Slings in Children: A Word for the Asymptomatic. Semin Thorac Cardiovasc Surg 2020; 33:492-500. [PMID: 32977012 DOI: 10.1053/j.semtcvs.2020.09.013] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Accepted: 09/08/2020] [Indexed: 11/11/2022]
Abstract
Vascular rings (VRs) are rare aortic arch anomalies that may present with a wide variety of symptoms related to esophageal and/or airway compression. We reviewed our surgical experience in both symptomatic and asymptomatic children. All children (n = 58) who underwent surgical repair of VRs or slings (mean age 27.4 ± 45.60 months; 36 males [62%]) between March 2000 and April 2020 were included. The most common anatomic variant was a right aortic arch (RAA) with aberrant left subclavian artery (ALSCA) (n = 29; 50%). Kommerell's diverticulum was present in 23 of these patients (79%). The second most common variant was a double aortic arch (n = 22; 38%), followed by pulmonary artery sling (n = 4; 6%), RAA with mirror image branching and left ligamentum arteriosum (n = 3; 5.2%), and left aortic arch (LAA) with aberrant right subclavian artery (n = 1; 1.7%). One patient had a double ring with pulmonary artery sling and RAA with ALSCA. Symptoms were present in 42 patients (72%). Left lateral thoracotomy was the approach in 50 patients (86%), while sternotomy was used in 8 (14%). Symptomatic improvement occurred in the majority of symptomatic patients (93%). There was one perioperative mortality (1.7%) in the symptomatic group which was non-VR related. Morbidities included recurrent laryngeal nerve injury in three patients (5.2%) and transient chylothorax in two (3.4%). Persistence/recurrence of symptoms resulted in one early and one late reoperation. The mean follow-up was 3 ± 5 years. In the current era, VR repair in children including asymptomatic ones can be performed with excellent results. We recommend complete repair of RAA with aberrant LSCA by resection of Kommerell's diverticulum and translocation of the ALSCA to avoid recurrence.

Dysphagia and an aberrant subclavian artery: more than just a coincidence. Interact Cardiovasc Thorac Surg 2020; 31:228-231. [PMID: 32539083 DOI: 10.1093/icvts/ivaa091] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 04/11/2020] [Accepted: 04/19/2020] [Indexed: 11/13/2022] Open
Abstract
Aberrant subclavian artery (arteria lusoria) is the most common congenital malformation of the aortic arch in the general population. As patients are more often asymptomatic, indications for correcting this abnormality, even in those having dysphagia, are very vague. While presenting a case of a 10-year-old girl who suffered from dysphagia lusoria for 2 years before being cured by a simple surgical translocation, we review the literature and debate various aspects of its management from diagnosis to surgery and cosmesis.

Safety and efficacy of a hybrid approach for repair of complicated aberrant subclavian arteries. J Vasc Surg 2020; 72:1873-1882. [PMID: 32665182 DOI: 10.1016/j.jvs.2020.01.075] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Accepted: 01/22/2020] [Indexed: 12/11/2022]
Abstract
OBJECTIVE Aberrant subclavian artery (ASA), a well-described aortic arch anomaly, is frequently associated with dysphagia and development of Kommerell diverticulum (KD) with aneurysmal degeneration. Historically, open repair has been performed, which can be associated with significant morbidity. More recently, hybrid approaches using different arch vessel revascularization techniques in combination with thoracic endovascular aortic repair (hybrid TEVAR) have been described, but there is a paucity of literature describing outcomes. The objective of this analysis was to describe our experience with management of complicated ASAs using hybrid TEVAR, further adding to the literature describing approaches to and outcomes of hybrid ASA repair. METHODS A retrospective, single-institution review was performed of all patients treated for ASA complications using hybrid TEVAR (2002-2018). The primary end point was technical success, defined as absence of type I or type III endoleak intraoperatively and within 30 days postoperatively. Secondary end points included complications, reintervention, and survival. Centerline measurement of KD diameters (maximum diameter = opposing aortic outer wall to diverticulum apex) was employed. Kaplan-Meier methodology was used to estimate secondary end points. RESULTS Eighteen patients (1.4% of 1240 total TEVAR procedures; male, 67%; age, 59 ± 13 years) were identified (left-sided arch and right ASA, 94% [n = 17]; right-sided arch and left ASA, n = 1 [6%]; retroesophageal location and associated KD, 100%); median preoperative KD diameter was 60 mm (interquartile range [IQR], 37-108 mm). Operative indications included diverticulum diameter (61%), dysphagia (17%), rupture (11%), rapid expansion (6%), and endoleak after TEVAR (6%). All procedures used some combination of supraclavicular revascularization and TEVAR (staged, 50% [n = 9]), whereas partial open arch reconstruction was used in 17% (n = 3). There were no perioperative deaths or spinal cord ischemic events. Major complications occurred in 22% (n = 4): nondisabling stroke, one; arm ischemia, one; upper extremity neuropathy, one; and iatrogenic descending thoracic aortic dissection, one. Technical success was 83%, but 44% (n = 8) had an endoleak (type I, n = 3; type II, n = 5 [intercostal, n = 2; aneurysmal subclavian artery origin, n = 3]) during follow-up (median, 4 months; IQR, 1-15 months). Two endoleaks resolved spontaneously, three were treated, and three were observed (1-year freedom from reintervention, 75% ± 10%). Median KD diameter decreased by 7 mm (IQR, 1-12 mm), and 78% (n = 14) experienced diameter reduction or stability in follow-up. The 1- and 3-year survival was 93% ± 6% and 84% ± 10%, respectively. CONCLUSIONS Hybrid open brachiocephalic artery revascularization with TEVAR appears to be safe and reasonably effective in management of ASA complications as evidenced by a low perioperative complication risk and reasonable positive aortic remodeling. However, endoleak rates raise significant concerns about durability. Therefore, if this technique is employed, the mandatory need for surveillance and high rate of reintervention should be emphasized preoperatively. This analysis represents a relatively large series of a hybrid TEVAR technique to treat ASA complications, but greater patient numbers and longer follow-up are needed to further establish the role of this procedure.

Abstract
The nonrecurrent laryngeal nerve (NRLN) is a rare anomaly of the inferior laryngeal nerve and is associated with the aberrant subclavian artery (negative Y sign). Despite the low incidence, the risk of iatrogenic injury to the NRLN is high without awareness of this anomaly. Neck ultrasonography is an effective method for detecting vascular anomalies and lowering the risk of vocal cord paralysis. We reported a case of a 39-year-old female with a right thyroid nodule. Neck ultrasonography revealed one ill-defined and hypoechoic thyroid nodule with dimensions of 1.6 cm × 1.0 cm × 0.6 cm and a negative Y sign. The fine-needle aspiration cytology report showed suspicion of a follicular neoplasm, Hurthle cell type. After discussing with the patient, the right thyroid lobectomy was arranged. During the operation, the right NRLN was confirmed. No vocal cord paralysis was noted after the surgery. The patient was finally diagnosed with Hurthle cell adenoma.

Abstract
Kommerell's diverticulum is a rare congenital vascular anomaly. Dysphagia is one indication for surgical intervention. We report on 4 consecutive patients who presented with dysphagia caused by Kommerell's diverticulum and underwent staged surgical treatment. The key to surgical treatment for such patients is to remove the vascular structure completely from the vicinity of the oesophagus.

Dysphagia of aberrant right subclavian artery treated by endoscopic dilation: An alternative to surgical treatment in select cases-A case report. Int J Surg Case Rep 2019; 66:118-121. [PMID: 31837613 PMCID: PMC6920218 DOI: 10.1016/j.ijscr.2019.11.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 11/13/2019] [Accepted: 11/16/2019] [Indexed: 10/25/2022] Open
Abstract
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.

Aberrant subclavian artery division and revascularization by a supraclavicular approach for definitive or staged treatment of dysphagia lusoria. J Vasc Surg 2019; 72:219-225.

Abstract
OBJECTIVE There is no consensus on the optimal approach to treatment of dysphagia lusoria (DL), especially in the absence of a Kommerell diverticulum (KD). We leveraged our institutional experience to clarify the safety and efficacy of aberrant subclavian artery (aSA) division with revascularization by a supraclavicular approach alone in patients with DL. METHODS We identified 10 consecutive patients who underwent surgery for DL at our institution between January 2007 and March 2019. Clinical and radiographic characteristics for all patients were collected. The primary outcome was improvement in dysphagia symptoms. Secondary outcomes included need for second-stage operation, postoperative complications, and long-term radiologic changes in the aSA remnant. RESULTS Seven patients underwent initial division of the aSA followed by revascularization through a supraclavicular exposure, and three had simultaneous supraclavicular and transthoracic intervention. Median follow-up was 52 (range, 1-143) months. In the four patients without a KD, a supraclavicular approach alone resulted in improvement in dysphagia symptoms. Conversely, the three patients who had a KD did not have durable relief of dysphagia and required a second-stage transthoracic procedure. Postoperatively, one developed a pulmonary embolism after supraclavicular approach alone and two patients developed complications after transthoracic intervention: left recurrent laryngeal nerve neurapraxia and pleural effusion requiring thoracentesis in one, and thoracic duct injury requiring reoperation in the second. Among those who underwent a single-stage procedure by a supraclavicular approach alone, no patients had aneurysm progression, rupture, or dissection after median follow-up of 60 (range, 1-100) months. CONCLUSIONS Division and revascularization of the aSA through a supraclavicular exposure in patients with DL result in durable symptomatic improvement in the majority of patients, particularly those without a concomitant KD. Patients with a KD may require a second-stage procedure to address the KD, but it appears safe to trial staged intervention rather than simultaneous operations to divide the aSA and to address the KD.

Abstract
OBJECTIVE The Kommerell diverticulum (KD) is an extremely rare developmental abnormality of the aorta related to an aberrant subclavian artery (ASCA). The objective of our study was to review the natural history of KD and ASCA using our single-center experience in diagnosing and managing KD and ASCA. METHODS A retrospective review of the Yale radiological database from January 1999 to December 2016 was performed. Only patients with KD/ASCA and a computed tomography (CT) scan of the chest were selected for review. The primary goal was to examine the natural history of KD and ASCA and the secondary goals were to review the management and outcomes of those patients treated for KD and ASCA. RESULTS There were 75 patients with KD/ASCA identified, with a mean age of 63 ± 19 years; 49 were female (65%). On CT scans, left- and right-sided aortas were present in 47 (63%) and 28 (37%) patients. A right ASCA or a left ASCA were present in 47 (63%) and 28 (37%) patients. Six patients were symptomatic on presentation. Symptoms included dysphagia, chest or back pain, and emboli to the fingers. The mean KD diameter was 21.8 ± 6.0 mm and the distance to the opposite aortic wall (DAW) was 48.3 ± 10.8 mm. Sixty-six patients were followed for a mean of 31.7 ± 32.5 months. One patient ruptured without repair. Nine patients underwent operative intervention, including eight open and one endovascular repair. Complications from operative intervention included ischemic stroke with hemorrhagic transformation, deep vein thrombosis and pneumonia. The mean growth rate for KD and DAW was 1.45 ± 0.39 mm/year and 2.29 ± 0.47 mm/year, respectively. On multivariable regression analysis, hypertension was a predictor of growth of DAW (P = .03). CONCLUSIONS KD is uncommon and shows a female predominance. The diverticulum grows, albeit slowly (KD and DAW growth rates of 1.45 ± 0.39 mm/year and 2.29 ± 0.47 mm/year). Most patients are asymptomatic, but dysphagia, chest/back pain, and distal emboli may occur. Rupture is rare. Symptomatic patients should be operated. Asymptomatic patients can be followed with serial CT scans.

Abstract
Objective Aberrant right subclavian artery (ARSA) is a rare anatomical variant of the origin of the right subclavian artery. ARSA is defined as the right subclavian artery originating as the final branch of the aortic arch. The purpose of this study is to determine the prevalence and the anatomy of ARSA evaluated with computed tomography (CT) angiography.
Methods CT angiography was performed in 3460 patients between March 1, 2014 and November 30, 2015 and the results were analyzed. The origin of the ARSA, course of the vessel, possible inadvertent ARSA puncture site during subclavian vein catheterization, Kommerell diverticula, and associated vascular anomalies were evaluated. We used the literature to review the clinical importance of ARSA.
Results Seventeen in 3460 patients had ARSA. All ARSAs in 17 patients originated from the posterior aspect of the aortic arch and traveled along a retroesophageal course to the right thoracic outlet. All 17 ARSAs were located in the anterior portion from first to fourth thoracic vertebral bodies and were located near the right subclavian vein at the medial third of the clavicle. Only one of 17 patients presented with dysphagia.
Conclusion It is important to be aware ARSA before surgical approaches to upper thoracic vertebrae in order to avoid complications and effect proper treatment. In patients with a known ARSA, a right transradial approach for aortography or cerebral angiography should be changed to a left radial artery or transfemoral approach.

Abstract
OBJECTIVES The present study analyzed the prevalence of variations of the aortic arch branching in Japanese population, comparing patients with aortic arch disease with healthy controls. METHODS Between from October 1999 and December 2015, 815 Japanese patients with aortic arch disease defined as aortic arch aneurysm (diameter ≥ 45 mm) and aortic dissection (group A) underwent aortic arch surgery in our institution. As a control group, 1506 traumatic screened patients were enrolled (group C). RESULTS Aortic arch anomaly was diagnosed in 140 patients (17.2%) in the group A and in 222 patients (14.7%) in the group C (p = 0.125). Significant differences were found in the incidence of aberrant subclavian artery (A: 14 patients, 1.7%, vs. C: 8 patients, 0.5%, p = 0.006). Significantly more patients with aortic arch aneurysm in the group A had anomalies of the aortic arch compared with the group C (p = 0.009), including bovine aortic arch (p = 0.049) and aberrant subclavian artery (p < 0.001). In term of aneurysm location, bovine arch was detected in more patients with proximal arch aneurysm (15.7%, p = 0.043), whereas aberrant subclavian artery was in more patients with distal location (3.7%, p < 0.001). No difference was found in aortic arch anomaly in patients with acute or chronic dissection. CONCLUSION Aberrant subclavian artery was a significant maker of aortic arch disease in Japanese populations. Bovine arch was a risk maker of proximal arch aneurysm, and aberrant subclavian artery was a risk factor of distal arch aneurysm.

Abstract
Background The right-sided aortic arch (RAA) is a rare congenital defect of the aorta. The aim of the study was to assess the occurrence of RAA in diagnoses performed by the University Radiology Department and analyze the frequency of concomitant vascular abnormalities. Methods The database of the Radiology Department was retrospectively analyzed between January 2008 and May 2016 with the keyword “right aortic arch”. Twenty patients with this diagnosis were identified from a total of 11,690 CT examinations of the chest area, 19,623 CT examinations of brain-supplying vessels, and 1863 MRI examinations of the heart and aortic arch or brain-supplying arteries. The type of aortic arch, the occurrence of Kommerell’s diverticulum and possible other vascular abnormalities, such as stenosis, kinking or occlusion, were then investigated. Results The analysis identified nine patients with type I and 11 patients with type II RAA. Eight of the 11 type II patients presented Kommerell’s diverticulum. Concomitant vascular abnormalities were detected in four patients with type II RAA. In two cases, the right common carotid artery (RCCA) was narrowed by up to 80%, with steal phenomenon confirmed in one of them. In the second coincident right subclavian artery (RSA) stenosis was depicted. In two other cases, the aberrant left subclavian arteries (ALSA) were found to be narrowed at the level of origin by up to 70%. One patient was found with type B aortic dissection including ALSA and Kommerell’s diverticulum. Conclusions Our observations indicate that concomitant vascular abnormalities may occur more often than reported in literature. Patients diagnosed with type II RAA should be examined with Doppler ultrasonography to identify coincident vascular disorders, especially stenosis of the common carotid arteries or subclavian arteries.

Abstract
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. We classified the positional relationship between the right subclavian artery and the membranous wall of the trachea into two types and used this method to predicate NRLN by identifying ARSA. Results Twenty‐six patients (0.96%) were identified with ARSA, all of which were cases of NRLN by CT. NRLN was identified during surgery in the 26 patients, and a normal right recurrent laryngeal nerve was observed in 2671 patients. The ARSA was detected on the dorsal side of the membranous wall of the trachea in all 26 NRLN cases, while it was detected on the ventral side in all 2671 recurrent laryngeal nerve cases. Conclusion Enhanced CT scanning is a reliable method for predicting NRLN by identifying ARSA. Preoperative recognition of this nerve anomaly allows surgeons to avoid damaging the nerve and abnormal vessels during esophagectomy.

Abstract
Kommerell’s diverticulum (KD) is defined as a bulbous dilatation of the origin of an aberrant subclavian artery due to a remnant of the left fourth aortic arch. We report the case of an asymptomatic woman in whom progressive thrombosis of the KD extending to the prevertebral tract of an aberrant right subclavian artery was detected at multidetector computed tomography imaging for lung cancer staging performed before and after the beginning of chemotherapy. Reversed blood flow in the ipsilateral vertebral artery due to subclavian steal phenomenon was also observed by color Doppler ultrasound examination.

Abstract
The development of multidetector computed tomography has triggered a revolution in the study of the aorta and other large vessels and has replaced angiography in the diagnosis of congenital anomalies of the aortic arch, particularly vascular rings. The major advantage of multidetector computed tomography is that it permits clear 3-dimensional assessment of not only vascular structures, but also airway and esophageal compression. The current update aims to summarize the embryonic development of the aortic arch and the developmental anomalies leading to vascular ring formation and to discuss the current diagnostic and therapeutic role of multidetector computed tomography in this field.

[PMID: 28616537 PMCID: PMC5454153 DOI: 10.1016/j.ijcha.2016.05.015] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2015] [Revised: 04/19/2016] [Accepted: 05/02/2016] [Indexed: 12/20/2022]
Abstract
Background CHARGE syndrome is a complex multiple congenital malformation disorder with variable expression that is caused by mutations in the CHD7 gene. Variable heart defects occur in 74% of patients with a CHD7 mutation, with an overrepresentation of atrioventricular septal defects and conotruncal defects — including arch vessel anomalies. Methods and results We report an index patient with an arch vessel anomaly underlying serious feeding problems that resolved after arch vessel surgery. This led us to examine the incidence of arch vessel anomalies in our previously studied cohort of 299 patients with a CHD7 mutation. Forty-two patients (14%) had an aortic arch anomaly, mostly aberrant subclavian artery or right aortic arch, which usually occurred in combination with other congenital heart defects (81%). The majority of these patients also had feeding problems that may be linked to their arch anomaly, but insufficient information was available to exclude other causes. Conclusions Arch vessel anomalies occur in a significant proportion of patients with a CHD7 mutation, and these anomalies may cause morbidity due to compression of the esophagus or trachea. Since symptoms of vascular compression can mimic those caused by other abnormalities in CHARGE syndrome, it is important to be aware of arch vessel anomalies in this complex patient category. Whether a solitary arch vessel anomaly is an indicator for CHARGE syndrome still needs to be studied, but doctors should look out for other CHARGE syndrome features in patients with arch vessel anomalies.

Abstract
Case report of a right subclavian retroesophageal artery (RSRA) found occasionaly on a chest CT. The malformation caused intermittent dysphagia. Patient presented with long history of upper digestive symptoms and gastroesophageal reflux disease.
We report a case of an uncommon anatomical anomaly in which a right subclavian retroesophageal artery (RSRA) was discovered during a routine chest CT scan in a patient with intermittent upper digestive symptoms (occasional dysphagia for solids, the so called “globus hystericus”). Subclavian arteries vary in their origin, course or length. RSRA is a relatively common embryological anomaly of the aortic arch. In this case we report a single carotid trunk. This variation is due to interruption of the fourth right aortic arch between the origins to the common carotid artery and subclavian artery, while the fourth left arch is intact. The regression of the proximal portion of the right subclavian artery occurs and the retroesophageal aortic arch persists, rarely leading to symptoms, as were present in this case.

Abstract
Aberrant right subclavian artery (ARSA) is a rare anomaly, in which the right subclavian artery arises directly from the aortic arch instead of originating from the brachiocephalic artery. This anomaly should be taken into consideration during surgical procedures around esophagus, such as esophagectomy. Any unintentional injury of this artery during surgical procedures could be extremely life threatening. A 56-year-old woman presented with dysphagia, with concurrent aberrant subclavian artery and esophageal cancer. The transhiatal esophagectomy was performed successfully since the anomaly was preoperatively diagnosed using computed tomography scan. The presence of ARSA during esophagectomy may be challenging, but if diagnosed preoperatively, the precise and diligent dissection of the retroesophageal space during esophagectomy, may prevent any injury to the aberrant artery and consequent complications.

Abstract
A fistula formation between the esophagus and an aberrant right subclavian artery is a rare but fatal complication that has been mostly described in the setting of prolonged nasogastric intubation and foreign body erosion. We report a case of a young morbidly obese patient who underwent sleeve gastrectomy that was complicated by a postoperative leak at the level of the gastroesophageal junction. A covered esophageal stent was placed endoscopically to treat the leak. The patient developed massive upper gastrointestinal bleeding secondary to the erosion of the stent into an aberrant retroesophageal right subclavian artery twelve days after stent placement. She was ultimately treated by endovascular stenting of the aberrant right subclavian artery followed by thoracotomy and esophageal repair over a T-tube. This case report highlights the multidisciplinary approach needed to diagnose and manage such a devastating complication. It also emphasizes the need for imaging studies prior to stent deployment to delineate the vascular anatomy and rule out the possibility of such an anomaly in view of the growing popularity of esophageal stents, especially in the setting of a leak.

Abstract
Aberrant right subclavian artery is a rare anatomical finding of abnormal embryologic development of the dorsal aorta and right subclavian artery. An associated aortic outpouching, or Kommerell diverticulum, may develop at the origin of the aberrant right subclavian artery. Given historically high rates of aneurysm rupture and mortality, early repair is indicated. Successful aneurysm exclusion can be accomplished with thoracic endovascular stent grafting following open carotid-subclavian bypass, maintaining upper extremities perfusion. Such hybrid techniques offer a decrease in mortality and complication rates. Herein, we describe a successful repair of a symptomatic (dysphagia, weight loss) aberrant right subclavian artery with Kommerell diverticulum using this hybrid open-endovascular approach.

Abstract
OBJECTIVE The aberrant right subclavian artery is a malformation of the aortic arch present at less than 2 % of the individuals in the general population. This incidence is higher in trisomy 21, making it possible use the aberrant right subclavian artery as a prenatal marker of trisomy 21. MATERIAL AND METHODS This work, which relates to a series of 11,479 consecutive fetal autopsies aims to measure the force of association between the aberrant right subclavian artery and trisomy 21, to confront our results with the sonographic series previously published and to contribute to assess the place that can have this sign in the echographic screening and the fetopathologic diagnosis of trisomy 21. RESULTS The isolated presence of an aberrant right subclavian artery does not represent an argument sufficient for the indication of a karyotype. But the detection of this anomaly must make pay a special attention in search of other associated signs. CONCLUSION On the results of this study, the aberrant right subclavian artery has to be considered as a part of the spectrum not only of trisomy 21, but also of many other congenital syndromes.

Abstract
When performing video-assisted thoracoscopic esophagectomy, the area at the level above the aortic and in the space between the esophagus and the spine, is usually regarded as a safe area for dissection of upper segment of thoracic esophagus. However, an aberrant right subclavian artery may appear in this area and lead to disastrous complications. We reported a case of aberrant artery encountered during video-assisted thoracoscopic esophagectomy. In order to avoid iatrogenic damage to this artery, it was converted to thoracotomy.

Abstract
First described in 1936, the diverticulum of Kommerell (DOK) is a dilatation of the proximal segment of an aberrant subclavian artery. Appearing more frequently in the left-sided aortic arch, the aberrant right subclavian artery passes behind the esophagus toward the right arm, causing symptoms in the minority of cases. Diagnosis is generally incidental with this pattern. When symptomatic, dysphagia, respiratory symptoms, hoarseness, chest pain, and upper limb ischemia are the most common complaints. Although debatable, the origin of DOK is accepted as being degenerative or congenital. The degenerative condition is normally associated with atherosclerosis and occurs more frequently after the age of 50 years with no gender predominance. Complications may be life threatening and are more commonly related to the diverticulum aneurysm or when associated with aortic diseases such as aneurysms or dissection. The authors present a case of a 67-year-old male with a history of acute chest pain, neurological disturbances, and hypertensive crisis. The diagnostic workup revealed an aortic arch aneurysm with intramural hematoma and a diverticulum aneurysm of Kommerell. Treatment was conservative at first. The patient presented a satisfactory outcome and was referred to an outpatient clinic for follow up and further therapeutic consolidation.
