A 1.5-year-old male German Shepherd dog was referred to a Teaching Veterinary Hospital with a chronic history of regurgitation and a previous presumptive diagnosis of megaesophagus. An esophagogram showed partial esophageal dilation, suggesting one vascular ring anomaly. Computed tomography identified a ...
SUMMARY: An aberrant right subclavian artery described by David Bayford, is rare and one of the aortic arch anomalies. It gives usually incidental findings. We present the case of a 57-year-old woman who was admitted to a neurology outpatient clinic due to a headache and no obvious pathology was detected...
SUMMARY: Aberrant right subclavian artery (arteria lusoria) is a rare embryological abnormality but the most common among aortic arch vascular anomalies. It represents an anatomical variant of right subclavian artery originating as the last branch of aortic arch, passing then retroesophageal to the norma...
Subclavian steal syndrome is a group of symptoms resulting fromretrograde flow in the
vertebral artery, “stealing” blood from the posterior intracranial circulation and other
territories, caused by stenosis or occlusion of the subclavian artery proximal to the
origin of the same vertebral artery, or ...
Abstract Objective The objective of the present study was to determine the frequency of malformations and chromosomal abnormalities in a population of fetuses with an aberrant right subclavian artery (ARSA). Methods This is a 6-year retrospective study of fetuses with a prenatal diagnosis of ARSA con...
The brachiocephalic trunk and the left subclavian artery originate from the aortic arch, and both supply blood to the head, neck, and thoracic limbs. Anatomical variations, such as an aberrant right subclavian artery, are congenital conditions rarely observed in dogs, Thus, the objective of the present r...
Abstract Aortic arch anomalies are not clinically important unless they cause compression symptoms due to aneurysmatic dilatation. Aortic anomalies need to be treated when they cause complex thoracic aortic diseases, and the treatment approach has evolved over time from open surgical methods, which have ...

RESUMEN: Durante el desarrollo embrionario suelen ocurrir anomalías a nivel del arco aórtico primordial. Una de estas es la arteria subclavia retroesofágica derecha (ASDR) la cual es un defecto frecuente de los arcos aórticos embriológicos y se debe a la interrupción del cuarto arco aórtico (AO) d...
When the proximal occlusion or stenosis of the subclavian or of the brachiocephalic
artery may require distal arterial filling through reversal flow from the vertebral artery,
causing clinically significant blood supply reduction to the brainstem, it is called
subclavian steal syndrome (SSS). We report a...
Objetivo: La arteria subclavia aberrante (ASA) o arteria lusoria, es una de las malformaciones más comunes del arco aórtico; en especial su variante derecha. Por otro lado, la arteria subclavia aberrante izquierda es más rara. Presentamos un caso infrecuente de un paciente con síndrome deleción 22q1...
