“…In the domestic animals, a right aortic arch, often resulting in the formation of a vascular ring, has been most often reported in the dog (2,3,10) and the cat (7,9), and some cases in horses (1, 8,11) and ruminants (4,12,13) are recorded. In this report, right aortic arch in a lamb and in two pigs is described.…”

“…9 The most frequently reported cases of multiple cardiac anomalies involve either persistent right aortic arch or patent ductus arteriosus (PDA) accompanied by another malformation. 5,7,8,10 Aortic tubular hypoplasia in the dog has only been reported once and was associated with a PDA, 14 while focal aortic hypoplasia of the left aortic arch in a dog combined with a double aortic arch and PDA has also been described. 10 In addition, coarctation (interruption) of the aorta as a single entity has also been reported several times in the dog.…”

Abstract. A Bulldog puppy that died at 1 day of age was presented for postmortem evaluation. Macroscopically, there was marked hypoplasia of the ascending, transverse, and proximal segments of the descending thoracic aorta and almost complete secondary thrombosis of the left ventricle causing a functional stenosis of the left atrioventricular valve. Separately, there was right atrioventricular valve dysplasia with secondary dilation of the right atrium. Microscopically, the left ventricular outflow tract was occluded by chondroid metaplasia, fibrosing recanalization of a left ventricular thrombus, and isolated Purkinje fiber degeneration and necrosis.

“…The PRAA is most frequently diagnosed in young large-breed dogs (Shires and Liu, 1981). The dogs with vascular ring anomaly usually have the history of postprandial regurgitation of solid foods soon after weaning (Van Den Ingh and Van Der Linde-Sipman, 1974;Helphrey, 1993). The affected dogs are stunted, thin and unthrifty (Helphrey, 1993;Muldoon et al, 1997).…”

The affected dogs are stunted, thin and unthrifty (Helphrey, 1993;Muldoon et al, 1997). A presumptive diagnosis can be made based on the clinical history, clinical signs, oesophagraphy and oesophagoscopy whereas; the confirmative diagnosis is best made after surgical exploration (Muldoon et al, 1997).…”

A 10-week-old, 4.5 kg female Weimaraner dog was referred to the Chonbuk National University, Animal Medical Centre with signs of regurgitation after weaning. The cervical oesophagus was palpable as a flaccid, air-filled cavity. The thoracic radiographs revealed oesophageal dilatation cranial to the heart and constriction at the level of third rib. A presumptive diagnosis was made as persistent right aortic arch (PRAA). A left 4th intercostal thoracotomy was performed and the definitive diagnosis was made as PRAA with left ligamentum arteriosum (LA) and an aberrant left subclavian artery (SA). The oesophagus was found dually compressed and severely necrosed. The corrective surgery comprised of transection of the LA as well as resection and anastomosis of the oesophagus, which resulted in a complete alleviation of the clinical signs.
