A 5-year-old, 1.36-kg, neutered male Yorkshire terrier was referred for evaluation of a persistent right aortic arch with concurrent megaesophagus. The dog was 3 months old when clinical signs were first noted, 2 years of age when diagnosed with megaesophagus, and 4 years of age when diagnosed with vascular ring anomaly (VRA). Surgical correction of the VRA was performed when the dog was 5 years of age, after gastrostomy tube feeding for 1 year to maintain nutritional requirements and mitigate the degree and duration of the esophageal distention. Thirteen months after surgery, the dog was eating soft dog food with no vomiting or regurgitation.

 Background: Vascular ring anomaly is considered a hereditary change. It occurs when the fourth right aortic arch persists instead of the fourth left aortic arch, forming a vascular ring that compress the esophagus causing esophageal dilatation cranial to the compression site. Diagnosis is based upon anamnesis, physical examination, clinical signs and complementary exams (radiograph, complete blood count and biochemical tests). The clinical treatment is inadequate, since the dilatation persists and tends to progress causing irreversible tissue injury. Surgical correction is indicated and consists of the arterial ligament resection and correction of the esophageal stenosis.Case: The objective of the current study is to report two case of persistence of right aortic arch in two cats referred to the Veterinary Hospital of the Federal University of Santa Maria. On physical examination the patients were alert, in good nutritional status, adequately hydrated and presented normal colored mucous membranes. Each animal underwent radiog­raphy and esophagogram with barium sulphate. The exam demonstrated partial esophageal dilation cranial to the cardiac silhouette, suggestive of vascular ring anomaly. An exploratory thoracotomy was performed in order to achieve the definitive diagnosis. The arterial ligament was resected and esophageal stenosis corrected. Anesthesia, surgery and the postoperative period undergo without any complications. Patients remained hospitalized in the first 24 h for observation and were dis­charged after this period. Ten days surgery they returned for revaluation and removal of the skin suture. Four months after the surgical correction the animals underwent a new radiography and esophagogram examination. Radiographic findings evidenced persistence of esophageal dilation and narrowing of the esophageal lumen. Patients were evaluated periodically up to 10 months after surgery, verifying excellent quality of life and remission of clinical signs.Discussion: Vascular ring anomalies affects both dogs and cats, occurring more commonly in purebred dogs than in mixed breed. The literature reports cases in young Siamese and Persian cats, although the absolute numbers are insufficient to make conclusions about the racial predisposition. This case report enrolled two cases of PRAA in adult mixed breed cats (one male and one female from the same litter). Surgical correction is the recommended treatment for PRAA, either con­ventional or minimally invasive techniques. To assist the dissection of the fibrous ring and correction of esophageal stenosis we utilized a 22 Fr Foley catheter, introduced through the oral cavity to the esophageal stenotic area. The inflation of the balloon on the constricted area allows visualization of residual fiber rings and facilitates its dissection and removal. The PRAA mortality is associated with late diagnosis and the coexistence of aspiration pneumonia. Therefore, surgery should be performed as soon as possible after the onset of clinical signs, in order to reduce damage to the esophageal muscles and nerves. It is estimated that 80% of cases survived the postoperative period. In both cases, no clinical signs were observed, and there was a reduction of the esophageal diameter compared with the previous dilation, as well as better esophageal transit. Ten months after surgery, the animals returned for revaluation, presenting adequate body development and good quality of life. As shown in this case report, surgical intervention allowed for the accurate diagnosis and correction of PRAA in cats, with remission of clinical signs and full recovery of the animal.Keywords: cat, regurgitation, megaesophagus, thoracotomy, anomaly.

Time Of Presentation

This study reports the survival to discharge, postdischarge survival, and long-term outcome of dogs following surgical correction of a persistent right aortic arch (PRAA). Information for 52 dogs, 28 dogs, and 23 dogs was available for analysis of survival to discharge, postdischarge survival, and long-term outcome, respectively. Ninety-two percent of dogs survived to the time of discharge and 18% of dogs surviving to discharge were euthanized within 2 mo of surgery. Breed, age at the time of presentation, and gender were not correlated with increased odds of death prior to discharge from the hospital. Long-term outcome for dogs was excellent in 30%, good in 57%, and poor in 13% of dogs. Although this study shows a relatively high mortality rate prior to discharge from the hospital and within 2 mo of surgical treatment, the long-term outcome is good or excellent in 87% of survivors. Dogs frequently display either residual clinical signs or require dietary modification long-term, but owner satisfaction is high.

Owner Satisfaction

We here report the diagnosis and surgical outcomes of a cat and three dogs with persistent right aortic arch causing oesophageal enlargement. The chief complaint in all cases was regurgitation just after solid food intake. Barium oesophagographic examinations revealed enlarged oesophaguses cranial to the heart and strictures due to arteriosus ligament constriction of the oesophagus. Surgical correction was carried out using left fourth intercostal thoracotomy and severance of the ligamentum arteriosum. The cases frequently displayed residual clinical signs and still required modified diets after a mean follow-up period of 8.6 months, but owner satisfaction was acceptable.

Successful Outcome

Vascular ring anomalies present in young patients and will inhibit growth and development. Therefore it is essential that these patients have the anomaly corrected as soon as clinically stable enough to undergo surgical correction. In particular the congenital malformation of the persistent right aortic arch (PRAA) is uncommon in practice to see, but does require good knowledge and understanding by the veterinary team to provide a successful outcome.

AbstractThe right aortic arch is a congenital vascular anomaly, which may form a vascular ring. However, prenatal identification of the branching pattern of brachiocephalic vessels is often limited. In this paper, we clearly demonstrated the branching pattern of brachiocephalic vessels in a case of right aortic arch with an aberrant left subclavian artery using HDlive Flow imaging.

This clinical case demonstrated surgical management for a rare case of vascular ring associated with an elongated and kinked aortic arch and a right descending aorta in a ten-year-old male using an extra-anatomic bypass grafting method and dividing the vascular ring. Computer tomography performed at six-month follow-up showed a favorable surgical outcome.
