We reported a case of megaesophagus for the fourth persistent right aortic arch in a puppy Cocker. The patient had a regular general condition, signs of regurgitation after eating, voracious appetite, weight loss and growth retardation. Simple and contrasted chest radiographic study revealed a distended esophagus frankly in his cervical and thoracic portions, cranial to the base of the heart, indicating a presumptive diagnosis of persistent right fourth aortic arch. We proceeded to surgical resolution for left intercostal thoracotomy with ligation of the ductus arteriosus, esophagus adhesion on base of the heart is freed and a chest drain was left for two days. The outcome was not as expected and the first 30 days of surgery were operated for the second time by thoracotomy with resection of the fifth rib, being adhesions of the ventral portion of the sternebrae megaesophagus. Flanges were released to proceed to posterior longitudinal elliptical removal of the entire ventral portion of esophageal dilation and sutured with simple points nonpenetrating. A chest drain was left for four days and a gastrostomy tube for fifteen days. The evolution was satisfactory with a medical release at four postoperative months.
