{"title":"Tracheal squamous cell carcinoma treated with tracheal resection and anastomosis in a dog.","authors":"Wayne Tsang, Kevin Choy, Kent Vince","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>A 9-year-old spayed female Labrador retriever was presented with intermittent expiratory cough and dyspnea unresponsive to prednisone and amoxicillin/clavulanic acid. Radiographic and computed tomographic examinations identified a localized dorsal intraluminal tracheal wall mass without detectable locoregional metastasis, leading to surgical resection and anastomosis of the affected tracheal segment. Histopathological analysis confirmed the mass as squamous cell carcinoma (SCC) with clear lateral and deep skeletal muscle margins. Monitoring after surgery, rather than adjuvant therapy, was elected by the dog's owner. The dog recovered with no complications noted and was in a state of clinical remission at the final in-hospital evaluation (3 mo after surgery). This case represents the second documented instance of canine tracheal SCC treated successfully with surgery. It underscores the potential for surgical intervention as a viable treatment option, potentially improving prognosis and survival outcomes in dogs affected by tracheal SCC. Regular evaluations and serial imaging examinations are recommended to monitor for recurrence and ensure long-term clinical remission. Key clinical message: This case marks the first documented tracheal resection and anastomosis as treatment for canine tracheal SCC and only the second reported tracheal SCC in a dog. Despite the typical negative outcomes associated with this SCC, the dog in this report achieved clinical remission without the need for chemotherapy or radiation therapy. Surgical intervention may be a viable treatment option for tracheal SCC, potentially improving prognosis and survival outcomes in affected dogs.</p>","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 6","pages":"622-627"},"PeriodicalIF":1.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12152688/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144282426","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":1.0,"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":1.0,"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}
