Persistent Right Aortic Arch (PRAA) is one of the most frequent congenital vascular system anomalies in dogs, responsible for the formation of a vascular ring that compresses the esophagus and can lead to the development of megaesophagus and recurrent regurgitation, especially during the post-weaning period. Given the clinical relevance of this condition and its potential complications, this study aims to report the anesthetic and surgical management of a PRAA case in a pediatric patient, highlighting the necessary care to minimize perioperative risks. The methodology consists of a case report from the Veterinary Hospital of the Federal Rural University of Pernambuco (UFRPE), involving a four-month-old mixed-breed female dog referred for surgical correction of the anomaly. Preoperative laboratory tests and clinical evaluation were performed, followed by a balanced anesthetic protocol using methadone and midazolam as pre-anesthetic medication, induction with propofol, and maintenance with inhalation anesthesia associated with a constant rate infusion (CRI) of remifentanil and lidocaine. Ultrasound-guided intercostal and serratus plane blocks were performed with bupivacaine and ropivacaine, respectively, along with continuous monitoring throughout the procedure. The intervention lasted approximately two hours and proceeded without relevant anesthetic complications, maintaining cardiovascular and ventilatory stability. In the immediate postoperative period, the patient showed satisfactory recovery with no episodes of regurgitation. It is concluded that the application of multimodal anesthesia, combined with intensive monitoring and adequate airway protection, significantly contributes to the safety and success of perioperative management in patients with PRAA.
