Variable pathways of lymphatic drainage have been described in the dog head and neck. The aim this study was to retrospectively assess patterns lymph node metastasis dogs with malignancies following bilateral mandibular medial retropharyngeal lymphadenectomy. Thirty-one were included. Median age at surgery 10 years (range: 5 months 14 years) mean bodyweight 21.4 ± 11.9 kg. Lymph occurred (45%), spread nodes 11 dogs. Eight 13 (62%) a lateralised lesion showed contralateral dissemination,...
The diagnostic accuracy of contrast‐enhanced CT for detection cervical lymph node metastasis in dogs is unknown. purpose this retrospective, observational, study was to assess the efficacy mandibular and medial retropharyngeal dogs. Histopathology with cancer head, bilateral lymphadenectomy reviewed. A single radiologist measured nodes derive short axis width long‐short ratios. Two blinded radiologists separately assessed margins, attenuation contrast enhancement each provided a final...
Abstract OBJECTIVE To describe the clinical characteristics, treatments, complications, and outcomes in dogs with nasal planum squamous cell carcinoma (SCC) undergoing local treatment.

Abdominal exploratory laparotomy, resections right chain mammectomy were performed....
Cross-sectional imaging may be used to characterise the location and extent of colorectal mesenchymal tumours (CRMTs). Given anticipated variation in tumour behaviour varying morbidity based on surgical margins, a reliable, non-invasive means predicting malignant potential could facilitate case management. The purpose this multi-institutional, retrospective study was determine diagnostic accuracy contrast-enhanced CT for distinguishing benign CRMTs. Twenty-seven dogs with CRMTs were...
ABSTRACT Objective To compare the pericardioscopic cardiovascular anatomy visible between apical pericardial window (PW) and sub‐phrenic pericardectomy (SPP). Study Design Experimental study. Animals Canine cadavers (n = 5). Methods Thoracoscopy was performed using a transdiaphragmatic subxyphoid right left intercostal portals. A 4 cm × PW created with endoscopic scissors. The intra‐pericardiac structures were then pericardioscopically assessed subjective ordinal scale (0: not visible, 1:...
To assess agreement between measurement of primary apocrine gland anal sac adenocarcinoma tumours using digital palpation, CT and formalin-fixed tissue to look for associations with metastasis at presentation.Retrospective study different methods measuring tumour size in histopathologically-confirmed canine adenocarcinoma.One hundred sixteen from 107 dogs were included. There was moderate maximal dimension the measured by compared palpation. no significant difference median maximum methods....
Abstract Veterinary studies have reported the outcome of adrenalectomies in dogs; however, these typically include a wide variety adrenal tumour sizes, including cases with or without vascular invasion. The purpose this study was to report cohort dogs histologically confirmed small tumours invasion treated adrenalectomy. This retrospective conducted using data from University Florida and California‐Davis databases between 2010 2017. Dogs were included if they underwent excision an gland...
To assess the effect of arthroscope insertion, using a carbon-fibre rod model, on humero-radial, humero-ulnar and radio-ulnar congruity, as assessed by computed tomography (CT).Cadaveric Greyhound elbow joints were at flexion angle 135 ± 5° CT. For condition 1, 36 mm fulcrum induced cubital valgus, used to aid insertion. conditions 2 3, single 1.8 or 2.5 diameter was inserted under arthroscopic guidance simulate position for assessment medial coronoid process. Repeat CT scans obtained all...
To develop and report a novel limb sparing technique for the distal radius in dog.Case report.A 14-year-old, female spayed Labrador Retriever with an osteosarcoma of right pathological fracture. A previous mast cell tumor had been treated 5 years prior to presentation marginal excision full-course radiation over metacarpal bones. The dog received 2 doses palliative just presentation.A standard resection was used as strategy salvage limb. Instead replacing 6-cm bone defect endoprosthesis,...
Objective To describe the clinical features and outcome of functional thyroid tumours in dogs. Materials Methods Retrospective multi‐institutional study 70 dogs diagnosed with mass concurrent hyperthyroidism. Clinical data regarding presentation, treatment, status were retrieved. Results Overall median survival was 35.1 months 1‐ 3‐year rates 83 49%, respectively. Median time 72.6 for treated surgical excision 15.7 that did not receive surgery. Of 50 by surgery which known following 64%...
Abstract Progressive disease is common following anal sacculectomy for apocrine gland sac adenocarcinoma (AGASACA); additional therapy may prolong survival. Adherence to medical recommendations influences therapeutic success in humans. The purpose of this study was assess the adherence follow‐up dogs with AGASACA. Medical records patients that underwent AGASACA, or without iliosacral lymphadenectomy, between July 2015 and 2018, were reviewed at eight referral institutions post‐operative...
Abstract Objective To determine the rate of nodal metastasis to medial retropharyngeal (MRP) and deep cervical lymph nodes in dogs surgically treated for thyroid carcinoma. Study design Retrospective study. Animals Twenty‐two client‐owned dogs. Methods Medical records between July 2015 October 2019 at Universities Missouri Florida were reviewed. Dogs that underwent thyroidectomy with concurrent elective MRP lymphadenectomy ± included. Tumor site, preoperative staging, histopathological...

Abstract Thyroid follicular tumours may take up iodide via the sodium‐iodide symporter. Knowledge of uptake could then allow treatment with I‐131 in dogs high‐risk tumours. The objective this study was to determine relationship between clinically detectable (as determined by scintigraphy and/or thyroxine concentrations) and sodium symporter immunohistochemical labelling on histologically fixed thyroid Nineteen were identified who diagnosed carcinoma underwent surgery from November 2017 July...
