title: Unusual Combination of Multiple Vascular Anomalies in a German Shepherd Puppy with Megaoesophagus.
abstract: A 2-months-old male German shepherd puppy was referred for regurgitation and delayed growth. Radiographic and endoscopic investigations revealed a precardiac megaoesophagus and oesophageal constriction at the level of the heart base. At post-mortem examination, a specific form of persistent right aortic arch characterized by an aberrant left subclavian artery in combination with a ligamentum arteriosum originating at the aberrant left subclavian artery (PRAA-SA-LA) was detected. A complete-type persistent left cranial vena cava (PLCVC) was also observed. This is the first report describing the association between PRAA-SA-LA and PLCVC in a dog with megaoesophagus.
