INTRODUCTION
Phrenic vessel-related portosystemic shunt (Pr-PSS)
is one of the major types in congenital extrahepatic portosystemic shunts (cEHPSS) in dogs. Its morphological characteristics have been well described in several studies. However, there are only few articles on clinical features of Pr-PSS in dogs.

INTRODUCTION
An Intussusception of gastrointestinal tract is uncommon in adult dogs and duodenogastric intussusception with pancreatic involvement is very rare form in veterinary medicine. There is considerable variation in etiology and most of the cases are idiopathic. The prognosis
and treatment outcome are variable depending on the severity of vascular compromise, abdominal organ association and underlying causes.
OBJECTIVES
A 6-year-old intact female crossbred dog was referred because of 4-days history of vomiting and anorexia. The dog was diagnosed of pancreatitis with severe azotemia. Repeated ultrasonography revealed typical views of an duodenogastric intussusception.
METHODS
Within midline celiotomy, the intussusception was identified. The pylorus, proximal duodenum and the segment of right pancreatic limb were prolapsed into
the stomach. The intussusception was reduced manually and a duodenopexy was performed. There was no polyp in the gastropyloric outflow and the thickening pyloric region was performed a full-thickness biopsy.
RESULTS
The dog recovered unevenfully from surgery and the biopsy result revealed submucosa edema without an evidence of malignancy. Upon follow-up, the dog has had no evidence of recurrence of duodenogastric intussusception for over 1 year.
CONCLUSIONS
As a rarity of duodenogastric intussusception, this case is unique in the present of pancreatitis due to gastroduodenal outflow obstruction and pancreatic involvement. Severe vomiting is the identifiable condition being the predisposing factor in both terms of primary and expectable recurrent evidences of this intussusception. Manual reduction and duodenopexy were accomplished for treatment and recurrent prevention.
    OBJECTIVES
To describe clinical features of Pr-PSS in 5 dogs and compare the characteristics with gastrocaval and splenocaval types of cEHPSS patients in the same institution from August 2015 to February 2018.
METHODS
Medical and surgical records were retrospectively analyzed for clinical presentation, history, physical examination findings, clinicopathologic data, diagnostic imaging findings, medical and surgical treatment, surgical complications, and outcome.
RESULTS
All five patients were non-Maltese breed dogs, while 9/10 (90%) of dogs of portocaval and gastrocaval cEHPSS were Malteses. Two patients who were diagnosed less than one-year-old had congenital abnormalities including hydrocephalus, patent ductus arteriosus, cryptorchism, ureterocele, and ectopic ureter. Two patients showed
no evidences related to cEHPSS while three patients presented with neurological signs including abnormal blood examination results. Older patients had age- related diseases such as cardiac disorders or liver mass. There was a major iatrogenic hemorrhage of a shunt vessel in a surgical procedure. In this case, the shunt had to ligate completely to control the bleeding. The patient had no signs of portal hypertension and all patients recovered well.
CONCLUSIONS
It is beneficial to perform computed tomography for non-Maltese small breed dogs with other congenital abnormalities to rule out or diagnose Pr-PSS due to the subclinical characteristics, diagnostic challenge with abdominal ultrasonography, and high prevalence
