“…Thus, we must be thorough in our evaluation of the major arteries on CT angiography, when presented with a PRAA as concurrent anomalies are frequently present. A second series that instead reviewed all canine thoracic CT studies over a three‐year period identified a vascular anomaly in eight of 802 dog 15 . In this case series, interestingly, an aberrant right subclavian artery was the most common anomaly, being identified in seven dogs.…”

A 7-week-old English Springer Spaniel presented with recurrent vomiting that began with the introduction of solid food. No musculoskeletal issues such as lameness were identified. On radiography, focal dilation of the oesophagus cranial to the heart base was identified. CT angiography confirmed the suspected persistent right aortic arch. A concurrent absent left subclavian artery was identified that has not been reported in detail previously. In addition, a bicarotid trunk and right subclavian artery branched directly from the aortic arch in lieu of a brachiocephalic trunk. A collateral blood supply via an intercostal and vertebral artery furnished the branches of the absent left subclavian artery. The dog developed aspiration pneumonia, deteriorated and was euthanised. BACKGROUND This case highlights a rare concurrent vascular anomaly in addition to the more frequently reported persistent right aortic arch. The knowledge of this may aid avoidance of a satisfaction of search error.

“…This is the first report demonstrating the use of CTA to depict the pre-and postsurgical anatomy of an ARSA. ARSA in dogs is rare, with only 17 cases described to date [1][2][3][4][5][6][7][8][9]. However, the previous surgical reports did not include visualization of collateral circulation of the right forelimb [6].…”

“…The aberrant right subclavian artery (ARSA) is a rare form of vascular ring anomalies (VRAs) in dogs [1][2][3][4][5][6][7][8][9][10][11]. VRAs are congenital vascular defects resulting from abnormal aortic arch development in young dogs and cats [10,11].…”

“…VRAs are congenital vascular defects resulting from abnormal aortic arch development in young dogs and cats [10,11]. Several types of VRAs have been reported in dogs, and the most common form is a persistent right aortic arch with a left arteriosum [1][2][3][4][5][6][7][8][9]. The other types include a double aortic arch, persistent right ductus arteriosus, and aberrant left subclavian artery.…”

A 1-year-old female Akita dog was referred for intermittent regurgitation. Computed tomographic angiography (CTA) showed an aberrant right subclavian artery (ARSA), resulting in constriction of the esophagus. After surgical ligation of the ARSA, CTA showed that the ARSA was not enhanced by contrast medium, and that sufficient collateral circulation of the right forelimb was supplied through the vertebral artery. Furthermore, the right and left vertebral arteries merged into the basilar artery at the level of the atlas, and no abnormal expansion of the ventral spinal artery was observed. Overall, we demonstrated the importance of post-surgical CTA for identification of surgical complications, including the formation of abnormal vessel alterations.

Persistent left cranial vena cava in an alpaca cria incidentally identified with computed tomography

A 12‐week‐old alpaca cria, that had been managed conservatively for a subluxation of the third and fourth cervical vertebrae (C) and possible C6–C7 subluxation identified several weeks previously following trauma at birth, was presented for investigations of acute onset tetraparesis. During investigations with computed tomography, a persistent left cranial vena cava, with an unusual phenotype, was incidentally identified with concurrent absence of the right cranial vena cava. The azygous vein could be seen crossing over the mediastinum to join the persistent left cranial vena cava, which continued caudally, passing left lateral to the heart and emptying into the caudal vena cava at the level of the diaphragm.
