Surgical correction and outcomes of persistent right aortic arch in two dogs

Abstract

The case report was consisted of two puppies with the complaint of chronic vomiting after feeding. The dogs were vomiting after eating and their abdominal areas were tense. Also, growth retardation was present. Accumulation of the contrast material was seen at the thoracic part of the esophagus with indirect radiographs in both cases. The cranial and caudal widths of the stricture in the esophagus were measured before and after surgery. The cranial and caudal parts of the stricture were found both dilated. The ligament that causing stricture was dissected by surgery and the stricture area was enlarged by balloon esophagoplasty. Case 1 was died on 2nd hour postoperatively, while Case 2 fully recovered and healed. In Case 2, the diameter of the prestenotic and poststenotic esophagus found decreased at 16th month postoperatively. The long-term results of Case 2 were fairly well.
