RESUMO

BACKGROUND: Few cases describing patients with a right aortic arch (RAA) or double aortic arch (DAA) and esophageal cancer (EC) have been reported. METHODS: We analyzed RAA and DAA cases treated with esophagectomy in our center's database and reported in English-language studies until April 1, 2023. Our study assessed the malformation characteristics and surgical details of EC patients with RAA and DAA. RESULTS: We extracted data of 24 EC patients with RAAs and 10 EC patients with DAAs. In both groups, the patients were more likely to be Japanese and male, to have squamous cell carcinoma and to have tumors located in the upper thoracic esophagus or middle thoracic esophagus. Left thoracotomy was commonly applied for RAA patients. For DAA patients, the proportions of left-sided and right-sided approaches were similar. Esophagectomy under video-assisted thoracoscopic surgery (VATS) in RAA or DAA patients had been performed on a routine basis in recent years. There were two anastomotic leakages in each group. Specifically, Kommerell diverticulum rupture occurred in 1 RAA patient; gastric tube dilation occurred in 1 DAA patient; and recurrent laryngeal nerve (RLN) injury occurred in 2 RAA patients. The postoperative course was uneventful for most patients in both cohorts. CONCLUSIONS: Esophageal carcinoma is rarely seen in patients with an RAA or DAA. To adequately dissect superior mediastinal LNs, an auxiliary incision (such as sternotomy), the left door open method or a preceding cervical procedure should be used appropriately. Esophagectomy, whether via thoracotomy or thoracoscopic surgery, can be performed safely for both RAA and DAA.

RESUMO

The combination of the right aortic arch and aberrant left subclavian artery (ALSA) with Kommerell's diverticulum (KD) is rare to coexist with the left innominate vein (LINV) beneath the aortic arch. It escalates the surgical risk undoubtedly and increases the difficulty of clinical procedures. We report one case diagnosed by Ultrasound and Computed Tomography Angiography (CTA).

RESUMO

OBJECTIVE: Vascular rings are often associated with respiratory and swallowing difficulties due to tracheal or esophageal compression. While the results of a vascular ring repair are considered excellent, the long-term effect of tracheal and esophageal remodeling and the persistence of symptoms have scarcely been reported. Our study aims to evaluate the respiratory and swallowing outcomes of vascular ring repair. STUDY DESIGN AND METHODS: A retrospective cohort study of children who underwent vascular ring repair between 2010 and 2022 in a tertiary-care children's hospital. RESULTS: There were 108 patients enrolled: sixty-three patients (57.41 %) with a right aortic arch, 42 patients (38.89 %) with a double aortic arch, and 3 patients (2.78 %) with other vascular rings. Forty-three (39.81 %) patients were diagnosed prenatally. Of the 65 patients (60.19 %) diagnosed postnatally, 35/65 (53.85 %) had either respiratory or swallowing symptoms as the indication for diagnostic workup. Persistent respiratory and swallowing symptoms were noted in 34/108 (31.48 %) and 30/108 (27.78 %) patients, respectively, within a year of surgical repair. Fourteen patients underwent repeated laryngoscopy and bronchoscopy that demonstrated residual tracheomalacia; however, only 2/14 (1.9 %) patients required tracheostomy tube placement, and 6-out-of-7 patients were weaned off positive pressure airway support. Persistent respiratory symptoms were significantly more common in patients with a double aortic arch compared to a right aortic arch. No differences were noted in demographics, comorbidities, and preoperative aerodigestive symptoms between patients with residual symptoms and patients with no residual symptoms. CONCLUSIONS: Persistent respiratory and swallowing symptoms after vascular ring repair are not uncommon. Postoperative evaluation should be pursued by a dedicated team, and treatment considered as appropriate.

RESUMO

INTRODUCTION: The presence of a double aortic arch (DAA) is manifested by compressive symptoms, requiring surgery. DAA cases are classified as either complete or incomplete type. DAA and a right aortic arch with mirror image branching (mRAA) have a similar configuration to the first branch artery. The first branch of the mRAA is the left brachiocephalic artery, which appears to be the same as that of an incomplete DAA due to blood flow interruption. The present retrospective study aimed to evaluate the differences between DAA and mRAA by fetal echocardiography. METHODS: This single retrospective cohort study included all patients diagnosed with complete DAA, incomplete DAA, or mRAA at our facility between 2010 and 2022. The patients were diagnosed with complete DAA, incomplete DAA, or mRAA after birth and remaining fetal echocardiograms. The patients were divided into the DAA (complete DAA: n = 4, incomplete DAA: n = 3) and mRAA (n = 4) groups. The following three outcomes were compared: (1) angle between the right aortic arch and first branch (RF angle), (2) ratio of height to width of the region bounded by the aortic arch, first branch of the aortic arch, and descending aorta, and (3) maximum tracheal diameter on a three-vessel trachea view. RESULTS: The incomplete DAA cases were difficult to diagnose via fetal echocardiography. On fetal echocardiography, the RF angle was significantly steeper in the DAA group than in the mRAA group (median 57° [36°-69°] vs. 75° [62°-94°]; p < 0.05). The DAA and RAA groups showed no significant differences in the ratio of height to width of the region bounded by the aortic arch, first branch of the aortic arch, and descending aorta (median 0.57 [0.17-0.68] vs. 0.73 [0.56-1.0]) and maximum tracheal diameter (median 2.5 [1.4-3.3] vs. 3.2 [2.8-3.5] mm). The cut-off value for the presence of DAA was an RF angle <71°. CONCLUSION: The DAA group (complete and incomplete DAA) had a significantly steeper RF angle than the mRAA group. Therefore, RF angle measurement could improve the fetal diagnosis and postnatal prognosis of DAA.

RESUMO

INTRODUCTION: The prenatal detection rate of a right aortic arch (RAA) has increased with the implementation of the three-vessel view (3VV) to the second-trimester anomaly scan formed by the pulmonary artery (PA), aorta (Ao), and superior vena cava (SVC). We examined the value of measuring the distance between PA and Ao in the 3VV in cases with an RAA. METHODS: We conducted a case-control study in which fetuses with an isolated RAA were matched to 3 healthy controls. Using 3VV images, the distances between PA, Ao, and SVC were measured and the ratio between PA to Ao (PAAo) distance and Ao to SVC (AoSVC) distance was calculated. RESULTS: Fifty-four RAA cases and 162 matched controls were included. The mean absolute distance PAAo was 3.1 mm in cases and 1.8 mm in controls (p < 0.001), and the mean PAAo/AoSVC ratio was 2.9 and 1.4, respectively (p < 0.001). The ROC curve of PAAo/AoSVC ratio showed a cut-off point of 1.9 with sensitivity and specificity over 87% for the diagnosis of RAA. CONCLUSIONS: The pulmonary-aortic interspace and the PAAo/AoSVC ratio were significantly larger for RAA cases as compared to controls. If an increased pulmonary-aortic interspace is observed, a PAAo/AoSVC of ≥1.9 can be helpful in the diagnosis of an RAA.

RESUMO

PURPOSE: A right aortic arch (RAA) is a rare vascular anomaly that often coexists with an aberrant left subclavian artery (ALSA). Due to the rarity of RAA, the development of an ALSA is not well understood. METHOD: We describe a case in which a 58-year-old man who was scheduled to undergo posterior decompression and fusion surgery for thoracic ossification of the posterior longitudinal ligament from Th1 to Th3 was found to have a RAA and an ALSA. RESULTS: Preoperative computed tomography angiography demonstrated a RAA and an ALSA. The ALSA was extremely tortuous and ran in the paraspinal muscles behind the thoracic laminae, which meant it was in the surgical field. The ALSA arose from the descending aorta and bifurcated into the left segmental arteries of Th1 and Th2, and also bifurcated into the left vertebral artery, which had a normal subsequent course. The dysplastic ALSA was considered to have developed from the thoracic intersegmental artery. Based on preoperative examination findings, we performed spinal surgery without vessel injury. CONCLUSION: We report a rare case of a dysplastic ALSA that developed from the thoracic intersegmental artery with a RAA. The knowledge of this anomaly provides safety in spinal surgery of the cervicothoracic junction.

RESUMO

PURPOSE: Here, we report a case of the right-sided aortic arch with isolation of the left innominate artery and hypoplasia of the left internal carotid artery. METHODS: A 42-year-old male patient underwent a whole-body computed tomography angiography (CTA) examination upon the clinical suspicion of vasculitis. RESULTS: CTA revealed a right-sided aortic arch with the isolation of the left innominate artery and hypoplasia of the left internal carotid artery. CONCLUSION: The right-sided aortic arch, with the isolation of the left innominate artery, is a scarce vascular variation that may occur with other cardiovascular anomalies such as ventricular septal defect. It can be asymptomatic or can present with symptoms of subclavian steal syndrome. Although its association with the agenesis of the left internal carotid artery has been reported, its association with the hypoplasia of the left internal carotid artery has not been reported previously to the best of our knowledge.

RESUMO

A right aortic arch is an anomaly of prenatal development characterized by location of aortic arch to the right from tracheal-esophageal complex. This variant of anatomy is usually asymptomatic and diagnosed accidentally. We performed open upper lobectomy for cancer of the upper lobe of the right lung in a patient with aortic arch dextraposition. Classical right-sided upper lobectomy in patients with right aortic arch is associated with certain difficulties. The most difficult objective is total excision of lymph nodes because trachea is hidden under aortic arch. A specific complication may be postoperative hoarseness associated with iatrogenic damage to the right recurrent laryngeal nerve.

RESUMO

AIM: This study aimed to characterize the pathological types, diagnosis, chromosomal abnormalities, and postnatal clinical manifestations of right and double aortic arch malformations in fetuses. METHODS: In this retrospective study, all fetuses diagnosed with right or double aortic arch anomalies for whom conventional two-dimensional echocardiography combined with spatio-temporal image correlation was performed at our tertiary referral center between December 2012 and December 2021 were included. RESULTS: In total, 234 fetuses with aortic arch abnormalities were identified. Forty-one cases lost to follow-up. One hundred ninety-three cases were included in this study. One hundred eighty-seven cases with right aortic arch. Six cases with double aortic arch. Most cases of right aortic arch with aberrant left subclavian artery (77/101, 76.2%) were isolated lesions, whereas most of those with mirror-image branching (45/75, 60%) were associated with intracardiac or extracardiac anomalies. Chromosomal abnormalities were screened prenatally in 113 fetuses with right aortic arch, among whom three with aberrant left subclavian artery (3/63, 4.8%) and eight with mirror-image branching (8/50, 16%) had chromosome anomalies (p < 0.05). Furthermore, three cases had microdeletion 22q11.2 and these were significantly associated with intracardiac malformations. CONCLUSIONS: Most cases of isolated right aortic arch do not present with clinical symptoms except isolated left subclavian artery and isolated left brachiocephalic trunk. In addition, the risk of chromosomal abnormalities in patients with isolated right aortic arch is very low. We recommend that pregnant women should be informed of the risks and benefits of undergoing invasive prenatal chromosomal detection.

RESUMO

Right cervical aortic arch is a rare malformation in which a right-sided aortic arch is unusually long, forms a loop, descends, and crosses behind the oesophagus to continue as a left descending aorta. We present a case of right cervical aortic arch associated with anomaly of epiaortic vessels and aortic obstruction, surgically treated with extra-anatomic bypass graft between ascending and descending aorta.

RESUMO

To evaluate prenatal findings of the right aortic arch (RAA), associated cardiac, extracardiac, and genetic anomalies, its perinatal outcomes and the need for postnatal interventions in cases of isolated RAA with a view to facilitating appropriate counseling. This was a multicenter, cohort study, that was undertaken in two international major cardiac centers between 2009 and 2020. The study subjects were prenatally diagnosed RAA cases with and without other structural cardiac defects. A RAA was identified in 137 fetuses. There were 84 cases of isolated RAA. Associations with additional intracardiac malformations were found in 53 (38.7%) cases. An extracardiac anomaly was observed in 26/137 (18.9%) fetuses, 11/84 (13.0%) fetuses with isolated RAA, and 15/53 (28.3%) fetuses with an additional intracardiac anomaly. The incidence of extracardiac and chromosomal anomalies was significantly higher in cases of RAA with abnormal intracardiac anatomy (28.3-18.8%, respectively), compared with RAA with normal intracardiac anatomy (13.0-5.9%, respectively) (p < 0.05). 22q11.2 microdeletion was found higher in RAA with CHD (4/18 fetuses) than isolated RAA (2/24 fetuses) (22.2% vs. 8.3% respectively). ALSA was present in 19.3% of cases. ALSA was more frequently observed in cases of isolated RAA (23.6%), than in RAA with structural CHD (7.6%) (p < 0.05). The pregnancy was interrupted in six fetuses, and one died in utero. The mortality rate was higher in fetuses with intracardiac anomaly than RAA without cardiac anomaly (11/49 (22.4%) vs. 2/81 (2.4%). Vascular ring formation was revealed in 21/98 cases. The RAA caused symptoms of a vascular ring in only one patient (0.7%) requiring surgery in the follow-up. Overall survival after initial diagnosis in the total cohort was 85.4% with 38 of 53 (71%) RAA with CHD cases and 79 of 84 (94.0%) isolated RAA cases. Chromosomal and extracardiac anomalies are lower in isolated RAA but not negligible hence amniocentesis should be routinely offered in all cases. The requirement for postnatal intervention in the immediate neonatal period is remote, therefore delivery of these fetuses need not be undertaken at a cardiac or surgical center.

RESUMO

BACKGROUND: A complex and rare form of double outlet right ventricle needs careful attention when choosing the optimal strategy for repair. AIM OF THE STUDY: To point out retrospectively what could have been done differently in our unique patient. METHODS: Primary repair was arranged in a neonate with double outlet right ventricle (of a non-committed ventricular septal defect type and lack of the outlet septum between the semilunar valves) with right aortic arch and dextro-malposition of great arteries. RESULTS: We managed to achieve intraventricular rerouting via a right ventricular incision concomitantly with the arterial switch maneuver. The patient is doing well with an excellent hemodynamic status. CONCLUSIONS: We considered that the radical approach we chose appeared to be sensible in this particular patient, although some other options could have been available.

RESUMO

PURPOSE: To give a report on the experience of our tertiary perinatology clinic on the pre- and postnatal management of the right aortic arch (RAA) by evaluating the patients as isolated and non-isolated RAA. MATERIALS AND METHODS: Patients referred to our perinatology clinic for fetal echocardiography were evaluated retrospectively. They were assessed in two groups: isolated RAA and non-isolated RAA. The isolated RAA group consisted of patients without any additional cardiac or extracardiac anomalies. According to our routine practice, all patients received detailed prenatal ultrasonography following fetal echocardiography and genetic counseling. RESULTS: A total of 60 patients were evaluated. 38 patients (63.3%) presented with additional cardiac anomalies. 21.7% had extracardiac anomalies, including 16.7% who also had cardiac anomalies. In 2 patients (3.7%) 22q11.2 microdeletion, in 2 patients (3.7%) trisomy 21, in 1 patient (1.9%) trisomy 13 and in 1 patient (1.9%) 20p12.1p11.23 (a deletion of 2880 kbp) were reported. The most common cardiac anomaly associated with RAA was Tetralogy of Fallot (25%). Fetal growth restriction was reported in 8.3% of the cases. 18 patients had isolated RAA. 16 out of the 18 patients had normal genetic analysis. 2 of them (11.11%) presented with a 22q11.2 microdeletion. CONCLUSION: A single-center experience on the diagnosis and management of RAA has been reported in this study. The results indicate that a prenatal cardiac evaluation in 3VV is of utmost importance in all pregnancies to detect RAA and refer these patients to the appropriate perinatology clinics for further evaluation and care.

RESUMO

BACKGROUND: Congenital anomalies of the aortic arch are important as they may be associated with vascular ring anomalies. The most common vascular ring anomaly in dogs is a persistent right aortic arch. However, published data of the distribution of the different types of vascular ring anomalies and other aortic arch anomalies are lacking. The objective of this retrospective descriptive study was to evaluate both the prevalence and the different types of aortic arch anomalies that can be detected using thoracic computed tomography (CT) examination. Archived thoracic CT examinations acquired between 2008 and 2020 at a single institution were retrospectively evaluated by 2 evaluators for the prevalence and type of aortic arch anomaly. Breed, age, and presenting complaint were obtained from the medical record system. RESULTS: A total of 213 CT studies were evaluated; 21 dogs (21/213, 9.9%) showed a right aortic arch and a left ligamentum arteriosum with compression of the esophagus. The following incidental additional findings were detected: aberrant left subclavian artery (17/21, 76.2%), branching from the persistent ductus arteriosus (PDA) (1/21, 4.8%), left-sided brachiocephalic trunk (3/21, 14.3%), bicarotid trunk (17/21, 81.0%), double aortic arch (1/21, 4.8%). One hundred ninety two dogs (192/213, 90.1%) showed a left aortic arch without esophageal compression. The following additional abnormalities were obtained in those dogs with left aortic arch: aberrant right subclavian artery (3/192, 1.6%) without clinical signs of esophageal compression, aberrant vessel branching from the aorta into the left caudal lung lobe (2/192, 1.0%), focal dilatation of the left or right subclavian artery (2/192, 1.0%), bicarotid trunk (1/192, 0.5%). CONCLUSION: Similar to previous studies an aberrant left subclavian artery is the most common additional finding in dogs with persistent right aortic arch. Newly, a left-sided brachiocephalic trunk was identified in 14.3% of the dogs with a persistent right aortic arch; no additional compression was caused by the left sided brachiocephalic trunk. Similarly, aberrant right subclavian artery can be an incidental CT finding without causing compression of the esophagus.

RESUMO

We report on the ultrastructural features of the aortic wall in a patient with Kommerell diverticulum. A 70-year-old woman with a right aortic arch, aberrant left subclavian artery, and Kommerell diverticulum underwent a successful total arch replacement plus the frozen elephant trunk procedure with anatomical left subclavian artery reconstruction. Small pieces of the ascending aorta, distal arch, right common carotid artery, and left subclavian artery were investigated ultrastructurally. In the ascending aortic wall, multiple cystic cavities were observed in the subintimal region of the media by scanning electron microscopy. Changes in organelles, including mild dilation of rough-surfaced endoplasmic reticulum and mitochondrial swelling and degrading, were also observed in all specimens by transmission electron microscopy. These ultrastructural features may indicate the fragility or stress of the aortic wall and are useful when considering the early surgical intervention of a patient with Kommerell diverticulum.

RESUMO

The objective of this study was to explore a new method for the differential diagnosis between fetal double aortic arch (DAA) and right aortic arch with mirror-image branches (RAA-MB). Clinical data and prenatal echocardiographic features of the DAA (n = 22) and RAA-MB (n = 65) confirmed by postnatal or autopsy findings were analyzed retrospectively. The angles between the two aortic arches in the DAA group and between the right aortic arch and the mirror branch were measured. The differences between the two groups and differential diagnosis value of the angles were compared and analyzed based on the receiver operating characteristic curve. The proportion of left-sided ductal arteriosus (100%) was higher in the DAA group than that (32.3%) in the RAA-MB group, (P < 0.05). The proportion of conotruncal anomalies is higher in the RAA-MB group (64.6%) than in the DAA group (18.2%) (P < 0.05). There was a significant difference in the angles between the groups (DAA: 50.3° ± 8.3° vs. RAA-MB: 82.9° ± 13.8°) (P < 0.01). When the cutoff value was 62.8°, the sensitivity and specificity of the differential diagnosis were 95.5% and 96.9%, respectively. Distinguishing the angle measurement between DAA and RAA-MB is helpful in prenatal prognosis. We recommend a cutoff value of 62.8°.

RESUMO

BACKGROUND AND AIM: Although the retroaortic left brachiocephalic vein in isolation is of no clinical importance, its recognition in the setting of associated lesions is important. We sought to address issues concerning the influence of isomerism, the establishment of diagnosis, and its importance in various surgical and interventional procedures. METHODS: A total of 80 published clinical and necropsy studies in the setting of a retroaortic left brachiocephalic vein described 250 patients. Clinical presentation, radiographic, ultrasonographic findings, contrast echocardiography, computed-tomographic angiocardiography, magnetic resonance imaging, and angiocardiography provided the diagnostic information prior to considering the surgical approach to the associated cardiac anomalies. RESULTS: Among 250 reported cases, three-quarters had associated congenitally malformed hearts. Of these 189 patients, all but seven had usual atrial arrangement. Right isomerism was reported in five patients and two patients having left isomerism. Almost two-thirds had tetralogy of Fallot or its variants, over four-fifths had malformations involving the outflow tract, two-thirds had a right aortic arch with two patients having a cervical aortic arch, and onepatient had double aortic arch. Various innovative individualized surgical procedures were employed with an overall perioperative mortality of 3.4%. CONCLUSIONS: Although the retroaortic left brachiocephalic vein is asymptomatic, its recognition during clinical investigation should raise the possibility of an association with other malformations, especially right aortic arch, ventricular septal defect, and anomalies of the outflow tracts. We submit that an increased appreciation of this venous anomaly may facilitate surgical planning, endovascular procedures, placement of central venous lines, and transvenous pacemakers.

RESUMO

We described a very rare case of aorto-pulmonary communication with right aortic arch and crossed pulmonary artery that cannot be placed in the typical anatomic classification of aortopulmonary window. At 23 weeks gestation, fetal echocardiography revealed a large tunnel-like communication connecting the great vessels proximal to the main pulmonary artery bifurcation, rather than a classic aortopulmonary window between the ascending aorta and the main pulmonary artery.

RESUMO

Right aortic arch in association with coarctation of the aorta and vascular ring is a rare anatomy. We present an infant with chromosome 22q11.2 deletion, who had the right aortic arch with retroesophageal aberrant left subclavian artery and left internal carotid artery. The left external carotid artery and right common carotid artery originated together from the ascending aorta as a bovine branch. The infant also had severe coarctation, which was prostaglandin dependent.

RESUMO

Ebstein anomaly is a rare congenital heart disease characterized by a varying degree of anatomical and functional abnormalities of tricuspid valve and right ventricle. It often coexists with other congenital cardiac malformations. Up to 79-89% of patients with Ebstein anomaly have interatrial communication in the form of patent oval foramen or atrial septal defect and more than one-third has other types of cardiac malformations. Association between Ebstein anomaly and right aortic arch is extremely rare and only few cases have been described in the literature so far. Much rarer than with other cardiac malformations, Ebstein anomaly is associated with non-cardiac malformations or genetic syndromes. Several cases of association between Ebstein anomaly and Charge syndrome have been reported, nevertheless, Ebstein anomaly accounts for less than 1% of cardiac defects seen in patients with Charge syndrome. In this case report, we present a unique case of a patient with Charge syndrome where both Ebstein anomaly and right aortic arch are present. The diagnosis of Ebstein anomaly and right aortic arch was established prenatally. In the first years of life, the patient did not exhibit any remarkable symptoms. However, over time, deterioration of right ventricle function and increased tricuspid regurgitation were observed, requiring consideration of surgical treatment at the age of five. In addition, delay in physical, motor, and mental development was observed and thus, at the age of five, the patient was consulted by a medical geneticist and a gene panel to test for structural heart defects was ordered. The test showed a mutation in chromodomain helicase DNA binding protein 7 (CHD7) gene, which, along with clinical features, allowed to establish a diagnosis of Charge syndrome. To the best of the authors' knowledge, this is the first case report of a patient with Charge syndrome, Ebstein anomaly, and right aortic arch that has been described in the literature.
