Megaesophagus for Resistence in the DuctusArteriosus Poodle Dog Breed – Case Report

Abstract

The esophagus is a tubular organ musculomembranoso colabável anatomically divided into three parts (cervical, thoracic,abdominal), which has the main function of food transportationand other content taken from the pharynx to the stomach. Being an organtransport, diseases such as esophageal achalasia (a descriptive termesophageal dilation) do not interfere directly in digestion or absorptionprocesses, however, may be an indirect cause of significant medical disorders,such as nutritional deficiencies resulting from the regurgitation offood, and increased risk of aspiration pneumonia. This report refers to aclinical case of a surgical-breed dog poodle, three years of age with severemalnutrition and a history of chronic regurgitation. Radiographic examinationshowed an extensive area of esophageal dilation. Was performedgastrostomy for feeding the patient, in order to improve their nutritionalstatus and prepare you for an exploratory thoracotomy. During thoracotomyconfirmed the patent ductus arteriosus, and proceed to surgicalcorrection of the anomaly. The patient recovered from surgery, but diedbecause of aspiration pneumonia after four days postoperatively. The ductusarteriosus caused by an abnormal development of vascular structuresderived from the definitive aortic arch during embryogenesis, was theprimary cause of megaesophagus. Therefore, we emphasize the importanceof early diagnosis of esophageal disease and its etiology in order toallow adequate surgical-medical treatment, better prognosis and betterquality of life for patients.
