Short- and Long-Term Outcome of Dogs Following Surgical Correction of a Persistent Right Aortic Arch

Abstract

This study reports the survival to discharge, postdischarge survival, and long-term outcome of dogs following surgical correction of a persistent right aortic arch (PRAA). Information for 52 dogs, 28 dogs, and 23 dogs was available for analysis of survival to discharge, postdischarge survival, and long-term outcome, respectively. Ninety-two percent of dogs survived to the time of discharge and 18% of dogs surviving to discharge were euthanized within 2 mo of surgery. Breed, age at the time of presentation, and gender were not correlated with increased odds of death prior to discharge from the hospital. Long-term outcome for dogs was excellent in 30%, good in 57%, and poor in 13% of dogs. Although this study shows a relatively high mortality rate prior to discharge from the hospital and within 2 mo of surgical treatment, the long-term outcome is good or excellent in 87% of survivors. Dogs frequently display either residual clinical signs or require dietary modification long-term, but owner satisfaction is high.

Thoracoscopy with Concurrent Esophagoscopy for Persistent Right Aortic Arch in 9 Dogs

“…Outcomes following open surgery for correction of PRAA are varied, with resolution of regurgitation reported in 9–92% of cases treated by a thoracotomy . Short‐term outcomes (<12 months) for dogs following thoracoscopic surgery for PRAA appear promising, with reduction in regurgitation in all reported cases and complete resolution in 64% of cases in a recent series of 14 dogs .…”

Megaesôfago Adquirido Secundário À Persistência Do Quarto Arco Aórtico Direito Em Cães Das Raças Pastor Alemão E Pastor Canadense: Relato De Casos

“…A persistência do quarto arco aórtico direito com ligamento arterioso à esquerda é a anomalia de anel vascular de maior ocorrência em cães, diagnosticada em 95% dos casos (KOÇ et al, 2004;BOTTORFF, 2012;KREBS, 2014).…”

“…As regurgitações nesses casos ocorrem logo após o desmame, quando o animal passa a consumir dietas sólidas (QUESSADA et al, 2010;MENZEL et al, 2011;KREBS et al, 2014). Devido a esse distúrbio digestivo, observa-se má condição corporal dos animais, embora estes, muitas vezes, apresentem apetite voraz (BARBUR et al, 2014), o que justifica o apetite depravado, inclusive com coprofagia, da paciente pastora alemã.…”

“…O tratamento cirúrgico tem como objetivo o alívio da constrição e seus consequentes sinais clínicos. É o mais indicado, visto que apenas o tratamento medicamentoso não tem bons resultados (KREBS et al, 2014).…”

Advances in Video-Assisted Thoracic Surgery, Thoracoscopy

“…Surgical transection of the ligamentum is Video-Assisted Thoracic Surgery, Thoracoscopy necessary and the prognosis is good to excellent in most cases, although some degree of esophageal dilation may persist. 17 Dogs are young and typically malnourished at the time of diagnosis and are therefore not ideal surgical candidates. Effort should be made to encourage nutritional support as best possible before surgical intervention, although treatment should not be delayed for an extended period of time.…”
