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.
一只2个月大的雄性德国牧羊犬幼犬因反流和生长发育迟缓前来就诊。影像学和内镜检查发现心脏前方有巨食管以及心脏基部水平的食管狭窄。尸检时，检测到一种特殊形式的持续性右主动脉弓，其特征为异常的左锁骨下动脉与起源于异常左锁骨下动脉的动脉韧带相结合（PRAA-SA-LA）。还观察到完全型持续性左头臂静脉（PLCVC）。这是首次报道在患有巨食管的犬中PRAA-SA-LA与PLCVC之间的关联。
