“…According to recent literature and the cases reported here, regurgitation remains the most prevalent clinical feature of dogs and cats with DAA and respiratory signs were more commonly associated with aspiration pneumonia rather than tracheal compression (Follette et al . 2019, Morgan & Bray 2019).…”

Objective To describe the clinical presentation, diagnostic findings, treatment and long‐term outcome following surgery of dogs and cats undergoing surgical treatment for a double aortic arch. Materials and Methods Medical records of dogs and cats diagnosed with a double aortic arch between 2005 and 2022 at three small animal referral hospitals were retrospectively reviewed. Long‐term outcome was assessed by a clinical examination and/or by contacting the owners or referring veterinarians. Results Two dogs and two cats were included. Regurgitation after eating, stunted growth and poor weight gain were the predominant clinical features. All animals had thoracic radiography and oesophagography; a dilation of the cranial thoracic oesophagus cranial to the heart base, was described in all animals. CT angiography confirmed double aortic arch in three of these and the right aortic arch was larger and appeared more well developed compared with the left aortic arch in all based on CT or surgical findings. Surgery was performed via a left fourth intercostal thoracotomy; ligation and transection of the lesser left aortic arch was performed. Follow‐up time ranged from 360 to 1563 days. All animals showed a marked improvement during the postoperative period, and all gained weight gradually. Owners' perception of the surgical procedure outcome and quality of life was described as excellent for all animals. Clinical Significance Surgical ligation of the lesser aortic arch in dogs and cats with double aortic arch is associated with a favourable prognosis for recovery, resolution of clinical signs, and quality of life with only minor feeding modifications.

“…In dogs, double aortic arch (DAA) is a rare, congenital vascular ring anomaly (VRA) infrequently published in the veterinary literature. [1][2][3][4][5][6][7][8][9][10][11][12] During normal embryological development, six symmetrical pairs of aortic arches develop from the aortic sac and fuse the right and left dorsal aortae. These vessels undergo selective regression and trans-Abbreviations: ACVR, American College of Veterinary Radiology; CTA, computed tomography angiography; DAA, double aortic arch; ECVDI, European College of Veterinary Diagnostic Imaging; PRAA, persistent right aortic arch; VRA, vascular ring anomaly.…”

“…3 The clinical presentation of patients is, therefore often seen in young animals following weaning due to chronic regurgitation of solid foods, coughing, and decreased body condition score. 9,13 The most common VRA in dogs is a persistent right aortic arch (PRAA) that occurs due to the anomalous regression of the left fourth aortic arch and persistence of the right fourth aortic arch, resulting in entrapment and subsequent compression of the esophagus by a complete vascular ring created by the main pulmonary artery ventrally and to the left, the aorta to the right, and the ligamentum arteriosum dorsally as well as to the left. 11,12 A previous study investigated the prevalence of vascular ring anomalies in 55 dogs and determined that PRAA accounted for 95% of these conditions, of which, six dogs had coexistence of the left aortic arch, compatible with a DAA malformation.…”

“…14 Embryologically, a DAA occurs due to the persistence of both the right and left fourth primitive arches, resulting in a complete vascular ring encompassing and compressing the esophagus and trachea. 9 Three distinct subtypes have been described in human medicine. The most common form reported is a dominant right aortic arch with a minor (hypoplastic or atretic) left arch.…”

Double aortic arch (DAA) is a rare, congenital anomaly in small animals, resulting in a complete vascular ring encircling the esophagus and trachea, and subsequent compression of these organs. Few studies have reported utilizing CT angiography (CTA) for diagnosing DAA in dogs; thus, the imaging features are currently lacking in the literature. The objectives of this retrospective, multicenter, descriptive case series were to report the clinical and CTA characteristics of DAA in surgically treated cases. Medical records and CTA images were reviewed. Six juvenile dogs met the inclusion criteria (median age: 4.2 months; range: 2-5 months). The most common clinical signs included chronic regurgitation (100%), decreased body condition (67%), and coughing (50%). Common CTA features of DAA included a dominant left aortic arch (median diameter: 8.1 mm) and minor right aortic arch (median diameter: 4.3 mm; 83%), an aberrant right subclavian artery arising directly from the right aortic arch (83%), segmental esophageal constriction (100%), and variable degrees of dilation cranial to the heart base, and marked tracheal luminal compression (median percent change: -55%; 100%) and leftward curvature of the trachea at the level of the bifurcation of the aortic arches (100%). All dogs underwent successful surgical correction with only minor postoperative complications. Due to the similarity of clinical and imaging characteristics described to that of other forms of vascular ring anomalies (VRA), CTA is vital for the specific diagnosis of DAA in dogs.

The material of this case report was a 4-month-old Jack Russel female dog brought to Burdur Mehmet Akif Ersoy University Veterinary Faculty Animal Hospital with the complaint of vomiting. Anamnesis revealed that the patient had chronic vomiting, cough, and respiratory distress following food intake. As a result of examinations, it was determined that the patient had a congenital right aortic arch-type vascular ring anomaly and related megaesophagus. Treatment consisted of a surgical procedure followed by medical therapy. This case report demonstrated that fluoroscopy-guided contrast-enhanced angiography can be used to diagnose vascular ring anomaly.
