This case report documents a progressive hepatopathy after central division hepatectomy in a 10-year-old female Lhasa Apso dog. Serum biochemistry at presentation for chronic urinary incontinence indicated a hepatopathy, with a liver mass identified on subsequent ultrasound. Referral for computed tomography (CT) (day 76) demonstrated a central division liver mass (~204cm<sup>3</sup>). A central division hepatectomy (right medial and quadrate lobes; gallbladder) was performed, with microscopic examination confirming a hepatocellular carcinoma. Serial biochemistry over a three-and-a-half-year follow-up documented progressive hepatopathy. Serial CT hepatic volumetry (day 76, 136, 1041) documented gross enlargement of the residual right lateral liver lobe and gross reduction of the residual left medial and lateral liver lobes. Biopsies of the left and right liver (day 187) demonstrated disparate pathology with microscopic features consistent with regeneration in the right liver and elevated portal vein pressure (PVP) in the left liver. This report documents progressive hepatopathy evidenced by serum biochemistry, disparate and persistent gross liver changes on posthepatectomy CT, and microscopic changes consistent with elevated PVP. Findings from this case demonstrate similarities to posthepatectomy liver failure (PHLF) and small-for-size-and-flow syndrome (SFSS) as reported in people and animal models. The progressive hepatopathy posthepatectomy in this case prompts consideration and further investigation for the development of PHLF and SFSS in the dog.</p>","PeriodicalId":8661,"journal":{"name":"Australian Veterinary Journal","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144207488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, to determine the time course between anaesthesia recovery and onset of clinical signs, and between recovery and any mortality. Secondly, to identify the common clinical signs and signalment of dogs with perioperative AKI. PubMed and CAB abstracts data bases using the terms \"(acute kidney injury OR acute renal failure) AND dog AND (anaesthesia OR surgery)\"; and ResearchRabbit were searched. Peer reviewed publications in English describing dogs that developed AKI with overt clinical signs after anaesthesia were included. Number of postoperative days until onset of clinical signs and death; along with signalment and the reported clinical signs leading to AKI diagnosis were extracted. Nine publications describing a total of 31 dogs were included in the review. Clinical signs were typically first seen 2-4 days postoperatively (range 1-14). Death/euthanasia occurred in 5 dogs; between 3 and 60 days postoperatively. Persistent renal dysfunction occurred in 4 survivors. The most common clinical signs were anorexia, lethargy, polyuria/polydipsia and vomiting. Female and larger breed dogs especially Labradors and Golden Retrievers were overrepresented.

This pigment was previously considered a storage disease, but more recently has been determined to be a metabolic breakdown product of tryptamine alkaloids within Phalaris species (spp) of introduced grasses. The study included 61 EGKs that were euthanased after a diagnosis of clinically advanced CPT, histopathological studies were performed on all cases and transmission electron microscopic studies on six brains. Histological examination of the brains from EGKs revealed brown pigmentation of neurons, particularly of large motor neurons, with accumulations of discrete granules in the cytoplasm that stained positive with stains used to identify melanin. This feature and the characteristic ultrastructural appearance of the pigment granules leaves little doubt that the pigment is primarily melanin in nature. Specifically, ultrastructural detail of the granules was consistent with neuromelanin present in the brains of higher order primates and humans and has been associated with susceptibility to neurodegenerative diseases in man including Parkinson's disease.

The objectives of this multicentre retrospective case series were to increase the awareness of veterinarians (including teleradiology providers) regarding <i>Spirocerca lupi</i> in Australia and to describe the thoracic radiographic findings of dogs infected with <i>S. lupi</i> with comparison to other endemic regions. Fifty-nine dogs with a diagnosis of canine spirocercosis were recruited from veterinary practices located in subtropical and tropical Australia. Many (54/59; 92%) originated from Mount Isa, Queensland, due to proactive screening. Thoracic radiographs identified 42 oesophageal masses in 35/59 (59%) of affected dogs. Identification of oesophageal masses was nearly always facilitated by oesophageal gaseous distension after gastro-oesophageal endoscopy, sedation or anaesthesia (33/35, 94%). Oesophageal masses were most frequently centred at T8. Where the aorta was visualised, aortic enlargement was detected in 17/42 (40%) dogs. Spondylitis was frequently detected (32/59; 54%) and most frequently located at T8-11. Spondylosis deformans was less frequently detected (14/59; 24%) but in 7/14 (50%) studies it was present concurrently with spondylitis. Spondylitis had varied morphological features, some of which were contrary to previously reported definitions. Despite this, the radiographic appearance of spondylitis allowed relatively reliable differentiation from spondylosis deformans and added significant confidence to the radiographic diagnosis of spirocercosis.
