Symmetrical double aortic arch in a beagle puppy

Abstract

Double aortic arch denotes the persistence of both fourth aortic arches and has been reported as 'very rare' in the dog. Most reported cases have been seen in German shepherd dogs. An eight-week-old, male, 1.5-kg beagle presented with a three-week history of regurgitation and dyspnoea. A barium oesophagram showed severe oesophageal constriction cranial to the base of the heart, and a provisional diagnosis of a persistent right aortic arch was made. A left-sided fourth intercostal thoracotomy was performed. The ligamentum arteriosum was ligated and divided. The oesophagus was seen lying on the right-hand side of the aorta. Postoperatively, the puppy deteriorated and was euthanized. Postmortem revealed a double aortic arch entrapping both the oesophagus and trachea. The inexperienced surgeon could consider computed tomography or angiography to determine the exact vascular ring, and other possible concurrent vascular anomalies present, before surgery.

Adult‐onset regurgitation in a dog with an aberrant right subclavian artery: a CT angiographic study

“…In cats and dogs, the most common VRA reported is a persistent right aortic arch with a left ligamentum arteriosum, accounting for 95 per cent of cases (Vangundy 1989, Buchanan 2004). Other VRAs reported in the veterinary literature include double aortic arch (Helphrey 1979, Suter and Lord 1984, Vangundy 1989, Buchanan 2004, Vianna and Krahwinkel 2004, Du Plessis and others 2006), right patent ductus arteriosus or right-sided ligamentum arteriosum (Helphrey 1979, VanGundy 1989, Hurley and others 1993, Holt and others 2000, Buchanan 2004), persistent right dorsal aorta (VanGundy 1989), abberant intercostal arteries (Bellenger 1970, VanGundy 1989) and aberrant left and right subclavian vessels (Detweiler and Allam 1955, Buergelt and Wheaten 1970, DeKleer 1971, Tsukise and others 1972, Helphrey 1979, Suter and Lord 1984, Bezuidenhout 1989, Griffiths 1989, VanGundy 1989, Buchanan 2004, House and others 2005, Park and others 2005, Yoon and Jeong 2011). …”

Double symmetrical aortic arch in a Czechoslovakian wolfdog - surgical treatment and health assessment four years after treatment: a case report

“…According to our knowledge only two of the reported cases in dogs survived the surgical intervention and were returned to their owners in good condition (Vianna and Krahwinkel 2004;Moonan et al 2007). In other cases, one dog was euthanised before the end of surgery (Martin 1983), one died 30 min after surgery (Findji and Degueurce 1999) and one on the second day post-surgery (Du Plessis 2006). Here, we have described the third case of treatment of a dog with double aortic arch and the second successful correction of a symmetrical aortic arch.…”

“…In addition to the genetic factors, in dogs and cats, teratogenic factors, infectious diseases affecting the mother in the first period of pregnancy, as well as vitamin A deficiency, are thought to play roles (Patterson 1968). In the cases described in the literature, the defect was found in three German shepherds (Martin et al 1983;Findji and Degueurce 1999;Moonan et al 2007), two crossbreed dogs (Findji and Degueurce 1999;Vianna and Krahwinkel 2004) and a Beagle (Du Plessis et al 2006). In the case described here, the dog was of a young breed obtained by crossing the Carpathian wolf with the German shepherd.…”

“…Only a few published reports regarding the double aortic arch in dogs are available (Aultman et al 1980;Martin et al 1983;Findji and Degueurce 1999;Ricardo et al 2001;Vianna and Krahwinkel 2004;Du Plessis et al 2006;Moonan et al 2007). It constitutes 1% of all vascular ring anomalies diagnosed in dogs and is even less frequent in other animal species such as Siamese cats (Yarim et al doi: 10.17221/274/2015-VETMED 1999, talapoin monkeys (Still et al 1979) and lions (Goldin and Lambrechts 1999).…”

Multidetector-row computed tomography of thoracic aortic anomalies in dogs and cats: Patent ductus arteriosus and vascular rings

“…Several of these anomalies, such as patent right ductus arteriosus, aberrant right subclavian artery, and some forms of double aortic arches, may necessitate a right intercostal approach [3]. Therefore, some authors recommend an additional angiographic examination before surgery [24,25]. In contrast, other authors have doubts about the use of angiography in these cases because the examination of aortic arch vessels has been proven difficult, even with biplane angiography, because of the 3-dimensional nature of vascular anomalies [23].…”
