“…A cellophane band and ameroid ring constrictor have been described to be effective for slow occlusion of portosystemic shunts (Hunt et al 2004;Frankel et al 2006;Leshem et al 2008). The cellophane band and banding technique described in the case reported here were the same as in a previous case report where computed tomography angiography demonstrated no evidence of portosystemic communication on the level of the cellophane band and caudal to the cellophane band (Yoon et al 2011).…”

A 4.3 kg, nine-year-old, spayed female Shih Tzu was presented for a two-month history of seizures, ataxia, and hyper-salivation. A diagnosis of a splenophrenic shunt was made by use of computed tomography angiography with volume-rendered imaging. A cellophane band was placed around the shunt after its isolation from the central tendon of the diaphragm. Clinical signs continued to wax and wane. Preprandial and postprandial bile acids levels were still elevated 10 months after surgery. An ameroid ring constrictor was placed around the shunt vessel before the vessel entered the diaphragm from its caudal aspect. At three months after the second surgery, the dog was near the normal ranges of preprandial and postprandial bile acids. Although a study of the anatomy of different types of extrahepatic portosystemic shunts has been reported in dogs, to the authors' knowledge, there is a lack of information on clinical presentation, treatment, and postoperative results in a specific type of extrahepatic portosystemic shunt, such as a splenophrenic shunt. Cellophane banding should be avoided for occlusion of a splenophrenic shunt passing along the central tendon of the diaphragm.

“…Ongoing studies to determine additional prognostic factors for surgical outcomes are expected to identify such prognostic tests in coming years. 5,[23][24][25][26][27][28] Presently, protein restriction without much emphasis on the source and quality of the protein often is used. The most stringent protein restriction is provided by renal diets, but several liver support diets also are available.…”

Background: Both presurgical preparation and long-term support of nonoperable dogs with congenital portosystemic shunts (CPSS) require optimal dietary management. Studies suggested that protein source may play an important role, with vegetable and dairy protein sources having better effects on hepatic encephalopathy (HE) than meat proteins.Objectives: Determine whether a low-protein test diet with soy as its main protein source results in better scores than a control diet with the same composition but with poultry as its main protein source in dogs with CPSS.Methods: In a double-blind cross-over study, 16 dogs received each diet for 4 weeks. Dogs in group T first received the test diet and then the control diet, whereas dogs in group C were fed the diets in the opposite order. Different variables (body weight, body condition score, HE score, fecal score, CBC, plasma tests of liver function including NH 3 , and coagulation tests) were measured at the start of the study and after completion of each diet.Results: One-way repeated measures ANOVA was performed. Plasma NH 3 was significantly lower after the test diet than after the control diet. The test diet also resulted in significantly higher fibrinogen concentrations and lower prothrombin times. The HE score improved with both diets, with no significant difference between the 2 diets.Conclusions: Both diets achieved a significant improvement in HE score. The influence of the soy-based diet on plasma NH 3 concentration and coagulation parameters suggests that such a diet decreases the risk for HE and gives better support of liver function.

“…Although understanding portal vein pressure (PVP) is important to identify whether these conditions involve PH, PH has been indirectly indicated in dogs based on clinical consequences including the development of ascites and acquired portosystemic collaterals (APSCs) [3,16]. Therefore, PVP in dogs has been mainly measured during the surgical attenuation of congenital portosystemic shunts (CPSS) under laparotomy [5,12,13,19].Catheterization is a minimally invasive method of measuring blood pressure. The currently favored method for determining PVP in humans involves catheterizing the hepatic vein and measuring wedged hepatic venous pressure (WHVP) and free hepatic venous pressure (FHVP) using a balloon catheter [1,2,6,10,11,14].…”

ABSTRACT. We compared wedged hepatic venous pressure (WHVP), splenic pulp pressure (SPP) and trans-splenic portal vein pressure (TSPVP) in healthy dogs. We found that portal blood pressure could be measured in dogs using any of these techniques. The WHVP, SPP and TSPVP were 7.8 ± 1.0, 6.2 ± 0.8 and 6.8 ± 1.2 mmHg, respectively. Measuring SPP using ultrasound is most simple and minimally invasive, and it might be useful for evaluating portal hypertension in dogs with liver diseases. KEY WORDS: canine, catheterization, portal hypertension, portal pressure, ultrasound. doi: 10.1292/jvms.11-0549; J. Vet. Med. Sci. 74(10): 1299-1302, 2012 Portal hypertension (PH) is caused by excessive resistance to a given blood flow in the portal circulation, and it is classified based on anatomical localization, such as prehepatic, intrahepatic, and posthepatic. In dogs, intrahepatic PH can be caused by parenchymal liver diseases, such as severe chronic hepatitis/cirrhosis (CH) and primary hypoplasia of the portal vein (PHPV) [3,16]. Although understanding portal vein pressure (PVP) is important to identify whether these conditions involve PH, PH has been indirectly indicated in dogs based on clinical consequences including the development of ascites and acquired portosystemic collaterals (APSCs) [3,16]. Therefore, PVP in dogs has been mainly measured during the surgical attenuation of congenital portosystemic shunts (CPSS) under laparotomy [5,12,13,19].Catheterization is a minimally invasive method of measuring blood pressure. The currently favored method for determining PVP in humans involves catheterizing the hepatic vein and measuring wedged hepatic venous pressure (WHVP) and free hepatic venous pressure (FHVP) using a balloon catheter [1,2,6,10,11,14]. The value of WHVP is equivalent to that of indirect PVP in dogs [4,15]. The splenic pulp can be percutaneously catheterized to obtain PVP using laparoscopic guidance [18], and thus measuring splenic pulp pressure (SPP) in dogs might be quite simple. The technique used for percutaneous trans-splenic catheterization of the portal vein using ultrasound guidance in anesthetized dogs has been described [9], and although it might be useful for managing PH, it has not been used to measure pressure. Furthermore, PVP has not been measured using the three techniques described above under the same conditions. The present study compares the outcomes of three minimally invasive methods of measuring PVP in healthy dogs. MATERIALS AND METHODSAnimals: Animals used in this study were six healthy beagle dogs, 3 males and 3 females, 3-6 (median, 5.2) years old and weighing 9.4-12.4 (median, 10.1) kg. All of the dogs were confirmed as being healthy by clinical examination, complete blood cell count, serum biochemistry, abdominal radiography and ultrasonography. All the dogs were cared for according to the principles outlined in the Guide for the Care and Use of Laboratory Animals approved by the College of Bioresouce Sciences, Nihon University.Anesthesia: The dogs were premedicated with atropine ...
