Gastroesophageal intussusception secondary to induction of emesis with subsequent development of septic pericardial effusion after corrective surgery

Abstract

A juvenile boxer dog was diagnosed with gastroesophageal intussusception that occurred after the induction of emesis with apomorphine. A ventral midline coeliotomy and diaphragmotomy were performed and the intussusception was manually reduced. Despite initial satisfactory recovery, the dog was diagnosed with cardiac tamponade 1 week post-operatively. Escherichia coli was cultured from pericardial and pleural effusion samples. During subtotal pericardiectomy surgery the pericardium was found to be markedly thickened with adhesions to the epicardium, thoracic wall and diaphragm. Substantial haemorrhage and refractory hypotension necessitated the administration of a blood transfusion during surgery. The dog entered cardiac arrest in the immediate post-operative period and cardiopulmonary resuscitation was unfortunately unsuccessful. Gastroesophageal intussusception should be considered a possible severe adverse effect of administering apomorhine to induce emesis in dogs. Additionally, septic pericardial and pleural effusions may occur post-reduction of gastroesophageal intussusception.

Septic pericarditis in a complicated case of non-associated immune-mediated hemolytic anemia in a Jack Russel terrier

“…A few reports of septic pericarditis in dogs have been described. Most cases are caused by bite wounds, migrating foreign bodies, postoperative infections and systemic infections (Fuentes et al, 1991;Aronson and Gregory, 1995;Casamián-Sorrosal et al, 2008;Veloso et al, 2014;Sheehan et al, 2019;Brincin et al, 2022). Only two cases of septic pericarditis in immunosuppressed dogs have been described.…”
