Background: Portosystemic deviation (PSD) is a congenital or acquired vascular anomaly that allows an abnormal bloodflow from the portal vein directly to the systemic circulation. This liver by-pass avoids hepatic metabolism of severaltoxins. Congenital PSDs are usually solitary and extra-hepatic, with a high incidence in pure-breed dogs. Acquired PSDsare usually multiple and occur as a consequence of portal hypertension. Surgery is the definitive treatment. Cliniciansand surgeons may present difficulties in the propaedeutic of animals with PSD. This paper aims at reporting a successfulsurgical treatment of a solitary extra-hepatic congenital PSD in a mixed-breed dog.Case: A 7-month-old mixed-breed dog, female, spayed, weighing 8 kg, was presented with a history of sudden syncopeafter feeding. Complementary exams revealed normocytic hypochromic anaemia, hypoalbuminemia and increased alanineaminotransferase and alkaline phosphatase. Abdominal ultrasound revealed an anomalous vessel inserted in the caudalcava vein, compatible with a congenital extra-hepatic PSD. Computed tomography revealed the anomalous vessel, with1,1 cm of diameter, originated from the cranial mesenteric vein and it inserted in the cranial margin of the caudal cavavein. A medical support was started with hydration, metronidazole, lactulose, probiotic and Hepatic diet. After 15 days thedog was submitted to surgery and a 5 mm ameroid constrictor ring was placed to gradually close the anomalous vessel.The dog recovered well and an abdominal ultrasound was repeated after 30 days, showing the ameroid constrictor ringring in the left cranial abdominal region, occluding the PSD close to its insertion in the caudal cava vein...

Background: Mammary tumours represent about 50 to 70% of all neoplasms in female dogs and their occurrence is directlyrelated to the reproductive status and patient´s age. The purpose of this research was to apply the Brazilian consensus ondiagnosis, prognosis and treatment of canine mammary tumours and to define the regional epidemiological aspects ofcanine mammary gland tumours in Vitoria metropolitan region (ES, Brazil) between 2012 and 2016 and to correlate themacroscopic characteristics such as lesion size and location of the neoplasm with histopathological diagnosis, tumoursgrade and lymph node metastasis.Materials, Methods & Results: Data were collected from the archives of the Laboratory of Animal Pathology of UVV andmedical records of patients attended at the Veterinary Hospital Prof. Ricardo Alexandre Hippler in 5 years (2012 to 2016). Theanimals were separated into groups by age to facilitate classification in the group with the highest occurrence of neoplasms. Theevaluation of the macroscopic characteristics was performed through the histopathological record described in the pathologylaboratory, for each patient, at the time of the initial evaluation. After descriptive analysis, data was correlated using Spearmanntest, and frequency dispersion was evaluated using chi-square test, both in the software Graph Pad Prism v. 6.01. This studyincluded 255 bitches and diagnosis of 486 lesions, once 48.6% of the dogs had more than one lesion, classified according tothe Brazilian Consensus for Canine Mammary Tumours and graded according to Elston and Ellis system. 86.8% of lesionswere consistent with actual mammary neoplasms, of which 67% were malignant and 20% were benign. Non-neoplastic lesionscorresponded to 7.2% of cases and 5.8% were extra-mammary neoplasms, with an increased incidence of lipomas (39.3%) andmast cell tumours (32.1%). Cross-breed dogs represented 26.7% of cases. Poodles (25.5%), Pinschers (9.8%) and Dachshund(4.7%)...(AU)
