Abstract

A sixteen-week-old female Akita-inu puppy was presented for investigation of acute vomiting, diarrhoea, and abdominal distension. Abdominal ultrasound revealed a single congenital right-sided intrahepatic portosystemic shunt and pylorogastric intussusception, which spontaneously resolved during the next three days after initial examination. Owners elected for euthanasia due to the clinical deterioration of the patient that reflected in development of clinical signs associated with liver insufficiency, guarded prognosis and financial concerns for transjugular coil embolisation.

Highlights

An intussusception is defined as a prolapse of one part of the intestine into the lumen of an immediately adjoining part (Anderson 1994) and has been reported in both humans and animals (Carr et al 1976; Anderson 1994; Bowersox et al 1991; Applewhite et al 2001; Broome et al 2004; Cole et al 2005; Barreau 2008; De Brito Galvao et al 2011; Berent and Tobias 2012; Choi et al 2012; Bertolini 2017)
A large aberrant vessel originating from the portal vein and leading to the caudal vena cava was detected in the right lateral liver lobe (Plate II, Fig. 4)
Intussusceptions may occur at any location within the alimentary tract and most invaginations occur in the direction of normal peristalsis (Marks 1983; Leib and Blass 1984; Lewis and Ellison 1987; Watson 1997)

Summary

Introduction

An intussusception is defined as a prolapse of one part of the intestine into the lumen of an immediately adjoining part (Anderson 1994) and has been reported in both humans and animals (Carr et al 1976; Anderson 1994; Bowersox et al 1991; Applewhite et al 2001; Broome et al 2004; Cole et al 2005; Barreau 2008; De Brito Galvao et al 2011; Berent and Tobias 2012; Choi et al 2012; Bertolini 2017). Intussusceptions most commonly occur at the ileocecocolic junction (Carr et al 1976; Marks 1983; Leib and Blass 1984; Lewis and Ellison 1987; Bowersox et al 1991; Huml et al 1992; Lamb and Mantis 1998; Applewhite et al 2001; Patsikas et al 2003; Barreau 2008; Lideo et al 2010).
