Non-thermal irreversible electroporation (N-TIRE) has shown promise as an ablative therapy for a variety of soft-tissue neoplasms. Here we describe the therapeutic planning aspects and first clinical application of N-TIRE for the treatment of an inoperable, spontaneous malignant intracranial glioma in a canine patient. The N-TIRE ablation was performed(More)
OBJECT Irreversible electroporation (IRE) is a novel nonthermal ablation technique that has been used for the treatment of solid cancers. However, it has not been evaluated for use in brain tumors. Here, the authors report on the safety and feasibility of using the NanoKnife IRE system for the treatment of spontaneous intracranial gliomas in dogs. METHODS(More)
BACKGROUND Central nervous system (CNS) manifestations of hypothyroidism have been associated with cerebrovascular complications. Reports of cerebrospinal fluid (CSF) abnormalities are rare in hypothyroid dogs. OBJECTIVE The aim of this study was to determine if chronic hypothyroidism causes blood-brain-barrier (BBB) abnormalities that are detectable(More)
BACKGROUND Intramedullary neoplasms of the canine spinal cord are infrequently reported. OBJECTIVE To describe distribution, clinicopathologic characteristics, radiographic findings, and clinical features of canine intramedullary spinal tumors. METHODS Retrospective series of histologically confirmed canine intramedullary spinal tumors. Contingency(More)
OBJECTIVE To report the frequency, types, and risk factors for acute perioperative adverse events (AEs) in dogs that had ventral slot decompression (VSD) for cervical intervertebral disc disease (IVDD). DESIGN Retrospective, case-control study. ANIMALS Dogs (n = 546) with cervical IVDD treated by VSD; 54 cases experiencing AE and 492 controls. METHODS(More)
Chronic canine hypothyroidism is associated with blood-brain barrier (BBB) disruption. We hypothesized that this change is mediated by endothelin-1(ET-1) and matrix metalloproteinases (MMP) -2, -9, and -14, as evidenced by increased concentrations of these proteins in cerebrospinal fluid (CSF) compared to controls. CSF from 18 dogs, 9 controls and 9 with(More)
Magnetic resonance imaging (MRI) is a common test for dogs with suspected intradural spinal cord lesions, however studies on diagnostic performance for this test are lacking. Objectives of this multi-institutional, retrospective, case-control study were to estimate sensitivity and specificity of MRI for (1) distinguishing between histopathologically(More)
Chronic inflammatory demyelinating polyradiculoneuropathy occurred in an 11-year-old Labrador Retriever dog. Spinal cord compression resulted from massive radiculitis with prominent cholesterol granulomas. Cholesterol deposition and associated granuloma formation is unique in chronic inflammatory demyelinating polyradiculoneuropathy, in both its human and(More)
BACKGROUND The stiff person syndrome (SPS) is a rare and debilitating autoimmune disorder with an unknown pathogenesis and variable clinical presentation that can present a diagnostic challenge. Although entities that clinically mimic stiff-person spectrum disorders (SPSD) have manifested in horses, they have not been reported in dogs. CASE PRESENTATION(More)
Intervertebral disk disease (IVDD) is common in dogs; cervical IVDD accounts for 13-25% of all cases. Ventral slot decompression provides access to ventral and centrally extruded or protruded disk material. However, procedures to remove dorsally or laterally displaced material are more difficult. This case series describes the use of perineural injection as(More)
