One year before referral, an abdominal mass was surgically removed and revealed to contain 2 testes with seminoma and rudimentary uterine tissue attached to it. At the time of referral, an abdominal mass had recurred; computed tomographic and histopathologic assessments of Tru-Cut (Merit Medical) biopsies revealed that the mass was lymph node metastasis of seminoma. Palliative-intent, intensity-modulated radiation therapy was delivered at the start as 15.2 Gy in 4 fractions over 2 consecutive days, and 4 wk later with 7.6 Gy in 2 fractions on the same day. Gross tumor volume reduced from 343.3 to 42.4 cm³ in 4 wk. The 15.2 Gy protocol was repeated after 6 mo, with further tumor size reduction to 29.3 cm³. Mild, small-intestinal diarrhea and decreased appetite were only noticed after the first radiation therapy and were self-limiting within 2 wk. To the best of the authors' knowledge, this is the first reported use of successful radiation therapy with a short-period protocol in a Yorkshire terrier with abdominal seminoma and persistent Müllerian duct syndrome. Key clinical message: A short-period radiation protocol was effective for the treatment of abdominal metastasized seminoma in a dog.</p>","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 6","pages":"604-608"},"PeriodicalIF":0.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12152682/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144282421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ophthalmic examination of OD revealed ventral keratitis, a hypermature cataract, equatorial lens capsule rupture, and anterior luxation of the lens nucleus. The right eye lacked a dazzle, direct, and indirect pupillary reflexes. No ocular anomalies were noted in the left eye. Enucleation of OD was conducted due to vision loss, the anticipation of constant need for medication to control uveitis, and the increased risk for secondary glaucoma. Histologic examination of OD confirmed a cataract, phacolytic uveitis, and lens epithelium migration and proliferation, consistent with lens capsule rupture. The extrusion of the cataractous nucleus could have been due to the powerful ciliary body muscles in otters. The contraction of these muscles may have increased the curvature of the anterior portion of the lens, causing the weakened lens capsule to rupture and extrude the nucleus into the anterior chamber.</p>","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 6","pages":"677-681"},"PeriodicalIF":0.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12152680/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144282428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Aortic cross-clamping, resection, and end-to-end anastomosis in a dog presenting with rib osteosarcoma.","authors":"Géraldine Lefeuvre, Eloise Lhuillery, Stéphane Libermann, Emilie Mongellas","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>A 3-year-old castrated male French bulldog was presented with a mass on the left thorax that had appeared 3 wk before the consultation. Blood analyses were unremarkable. Computed tomography revealed a large heterogeneous mass arising from the 10th rib, invading the left chest, contiguous to but not infiltrating the aorta. Based on biopsies, the diagnosis was an osteoblastic osteosarcoma. Surgical treatment occurred 10 d after the computed tomographic scan and biopsies. Due to a rapid increase in the tumor's extent, the aorta was partially surrounded by the mass. Poor visibility led to an accidental aortic section with a vessel-sealing device (LigaSure; Covidien). Aortic cross-clamping allowed a 25-millimeter-long resection of the descending aorta from T7 to T11, followed by an end-to-end anastomosis. Postoperatively, the dog had temporary hind-limb ataxia for < 2 wk. At 4 mo postoperatively, the dog was euthanized due to the reappearance and degradation of new neurological symptoms associated with a left paravertebral recurrence of the tumor with slight penetration of the vertebral canal. Necropsy revealed no long-term ischemic lesions in any abdominal organ or the spine, but there was spinal cord axonal degeneration (attributed to chronic mild compression). However, the site of recurrence of the tumor-induced neurological symptoms was unrelated to the aortic resection and cross-clamping. Key clinical message: Aortic cross-clamping, resection of the descending aorta, and their neurological sequelae induced by ischemia are rarely described in nonexperimental studies in veterinary medicine. This is the first report of an 18-minute cross-clamping and a 25-millimeter-long resection of the descending aorta in which aortic cross-clamping and resection were done as an unplanned salvage procedure, and of its outcome 4 mo later, with no long-term ischemic lesions.</p>","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 6","pages":"609-616"},"PeriodicalIF":0.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12152696/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144282391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this review is to evaluate the consequences of severing the jugular veins. In animal slaughter, when the jugular vein is transected, air travels antegrade into the right ventricle due to the powerful suction effect of right ventricular diastolic function and retrograde into the cerebral circulation, due to the natural buoyancy of the air bubbles. Air sucked into the heart induces hypotension because it creates an 'air lock' in the heart and elicits reflexes in the pulmonary arteries. Air exceeding the pulmonary filtration threshold travels to the left ventricle where ejection creates emboli leading to systemic organ ischemia. Air emboli travelling to the brain through the vertebral artery produce cerebral ischemia, which will further accelerate the brain damage produced by the severed carotid arteries. Air embolism is a well-documented cause of death in animals as well as humans, and the larger the volume of air entering the circulation the faster death will ensue. Veterinarians should consider air embolism as another pathway in ritual slaughter that can lead to rapid animal death.</p>","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 5","pages":"564-567"},"PeriodicalIF":0.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12044623/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143982819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
