A 4-month-old female mixed breed dog was presented to the University of Tennessee College of Veterinary Medicine with a history of regurgitation and cachexia. Thoracic radiographs revealed focal megaesophagus cranial to the heart base. Magnetic resonance imaging (MRI) was performed. True fast imaging with steady-state precession (TrueFISP), fast low angle shot (FLASH), and short tau inversion recovery (STIR) sequences were acquired prior to contrast medium administration. Contrast-enhanced magnetic resonance angiography (CE-MRA) demonstrated focal megaesophagus and position of the aortic arch to the right of the esophagus. A small ductus diverticulum and an indistinct linear soft tissue band crossing the esophagus were also noted. Surgical exploration confirmed MR diagnosis of a persistent right aortic arch (PRAA) with left ligamentum arteriosum. The dog improved following surgery but was unable to be transitioned to dry food. To our knowledge this is the first report describing the use of CE-MRA for preoperative diagnosis and guided surgical treatment of a vascular ring anomaly in a dog.

Vascular rings are usually repaired via left thoracotomy. We report our series of pediatric patients with vascular rings that were repaired thoracoscopically. From February 2002 to September 2004, 13 patients underwent video-assisted thoracoscopic surgical techniques (VATS) division of their vascular ring. Chest magnetic resonance arterography (MRA) and/or computed tomographic arteriography (CTA) were used to evaluate the vascular ring in most patients. Patients were chosen for VATS repair based on surgeon's choice and type of vascular ring. Data are expressed as mean ± SD. The Children's Healthcare of Atlanta Institutional Review Board approved this retrospective chart review. Age and weight was 1.5 ± 1.8 years (range: 4 months–17 years) and 16.0 ± 12.5 kg (range: 6.0–22.1 kg), respectively (n = 13). Associated diseases included congenital heart disease (n = 2). Symptoms included respiratory complaints (n = 6), dysphagia (n = 2), dysphagia and shortness of breath (n = 1), pneumonia (n = 2), tracheal deviation (n = 1), and one patient was asymptomatic. Vascular ring types included double aortic arch (n = 4) and right aortic arch with an aberrant left subclavian artery and a left ligamentum arteriosum (n = 9). Operating time was 70 ± 20 minutes (range: 46–122 minutes). One patient had to be opened because of a large arch. Length of stay was 1.9 ± 0.9 days (range: 1–3 days). There were no complications, and all patients improved clinically at follow-up. Thoracoscopic repair of certain types of vascular rings seems to be safe and effective in children. More patients, however, need to be studied.

Chest X Ray

A 24-year-old woman was referred to pulmonologist with worsening breathlessness and wheeze. During childhood, she was diagnosed with asthma and subsequent exacerbations were treated with bronchodilators for many years. The chest X-ray and a spirometry testing raised a doubt of extrinsic tracheal compression and a subsequent enhanced chest CT (computerized tomogram) scan confirmed a right-sided aortic arch and a vascular ring anomaly compressing the trachea. Standard surgical division of ligamentum arteriosum was able to relieve the trachea and so the symptoms.

Esophageal Dysfunction

Abstract Case Description—3 alpaca crias and cadavers of an alpaca cria and a llama cria were evaluated for evidence of esophageal dysfunction. Clinical Findings—All 5 crias were between 3 and 5 months of age when clinical signs developed, and all had a thin body condition when examined. Clinical signs included coughing, regurgitation, and grossly visible esophageal peristaltic waves. A barium esophagram was used to diagnose esophageal obstruction, megaesophagus, and a vascular ring anomaly (VRA). Fluoroscopy was used to evaluate deglutition, esophageal peristalsis, and the extent of esophageal dilation in 1 alpaca cria. A persistent right aortic arch was identified in 1 alpaca cria, and a left aortic arch with right ductus arteriosus or ligamentum arteriosum and an aberrant right subclavian artery were identified in the 4 remaining crias. Treatment and Outcome—Surgical correction of the VRA was attempted in the 3 live alpaca crias. It was complicated by the conformation and location of each VRA and inaccurate anatomic diagnosis of the VRAs before surgery. Treatment was universally unsuccessful because of intraoperative complications and the persistence of clinical signs after surgery. Clinical Relevance—Megaesophagus is typically an idiopathic condition in camelids. However, these findings suggested that camelids with esophageal dysfunction during the neonatal period may have a VRA. The prognosis is grave for camelids with VRA, and accurate anatomic diagnosis of the VRA via the use of advanced imaging techniques (eg, angiography, computed tomography, or magnetic resonance imaging) may improve the success of surgical intervention.

Associated Malformations

<strong>Introduction</strong>: Anomalies of the aortic arch are frequent congenital malformations, which rarely form partial or complete vascular rings. A rare form of vascular ring is the encircling, or circumflex, aortic arch.<br /><strong>Case Report</strong>: A 19-month-old boy, with no respiratory symptoms, was referred for ventricular septal defect (VSD) repair. Cardiac magnetic resonance imaging and echocardiography confirmed the perimembranous VSD, a bicuspid aortic valve with normal function, and showed a right-sided ascending aorta, bifurcating to the left behind the esophagus and trachea above the tracheal bifurcation, with a left-sided descending aorta, a left ligamentum arteriosum and aberrant left subclavian artery, realizing a circumflex aortic arch. The child underwent successful VSD repair and ligamentum arteriosum division, with an uneventful postoperative course.<br /><strong>Conclusions</strong>: Previous reports have described the association of circumflex aortic arch with VSD, but there is no previous report of its association with VSD and bicuspid aortic valve. Patients are usually symptomatic either preoperatively, or after VSD repair. For this reason, division of the ligamentum arteriosum, to open the vascular ring and free the trachea and esophagus from compression, should be performed in patients undergoing cardiac surgery for associated malformations.

Vascular rings constitute 2% of all congenital cardiac malformations. Accurate prevalence is difficult to estimate because of the lack of symptoms in a significant proportion of cases. ‘Vascular ring’ refers to a variety of congenital vascular anomalies that encircle (partly or completely) and compress the oesophagus and trachea in the upper mediastinum. The vascular structures are not always patent (i.e. ligamentum arteriosum, atretic segment of aortic arch) but can still cause symptoms. The majority are isolated anomalies but some are associated with additional structural congenital cardiac defects. Most can be understood from the Edwards schematic model of a double aortic arch.
