Objective This case series describes the clinical presentation, management and outcome of three cats diagnosed with cervical intervertebral disc disease that underwent decompressive ventral slot surgery. Methods This is a retrospective case series evaluating client-owned cats undergoing a ventral slot surgical procedure to manage cervical intervertebral disc disease (n = 3). Results A routine ventral slot surgery was performed in each case without complication, resulting in postoperative neurological improvement in all three cases. Clinical Significance Ventral slot surgery can be used to achieve effective cervical spinal cord decompression with a good long-term outcome in the management of feline cervical intervertebral disc herniation. To avoid creating an excessively wide slot with the potential for postoperative complications including vertebral sinus haemorrhage, vertebral instability or ventral slot collapse, careful surgical planning was performed with preoperative measurement of the desired maximum slot dimensions.

Objectives The aim of this study was to evaluate the outcome and prognosis of thoracolumbar feline intervertebral disc disease (IVDD) treated by surgical decompression. Methods This was a multi-institutional retrospective study evaluating the age, breed, sex, body weight, presenting complaint, neuroanatomic diagnosis at presentation, diagnostic imaging results, surgery performed and the overall outcome at discharge and at recheck. Bivariable associations between variables were assessed using the Kruskal–Wallis test (age and grade of IVDD at presentation) and Fisher’s exact test (grade of IVDD at presentation and outcome). Results A total of 35 cats met the inclusion criteria for the study. The most frequently reported clinical sign was difficulty walking (54.2%). The majority of cats presented with an L4–S3 localization (57%). The most common site of intervertebral disc herniation (IVDH) was at L6–L7 (34%). The majority of feline patients that received surgery had a positive outcome at the time of discharge (62.5%; n = 20/32) and at the time of the 2-week recheck (91.3%; n = 21/23). No association was identified between the age of the patient and the grade of IVDD. No association was identified between the presenting grade of IVDD and the clinical outcome at the time of discharge or at the time of recheck evaluation. Conclusions and relevance Cats undergoing spinal decompressive surgery for thoracolumbar IVDH appear to have a favorable prognosis independent of the initial presenting grade of IVDD. A larger sample size and a longer length of follow-up is necessary to obtain statistical associations between the presenting grade of IVDD and overall clinical outcome.

AbstractTo review and evaluate the literature reporting results of prophylactic surgical procedures for Hansen’s type I intervertebral disc disease.Systematic literature review.Online bibliographic searches of abstracts through PubMed and the Veterinary Information Network (VIN) were performed using the searchable term “canine intervertebral disc disease and recurrence”. The resources were evaluated in regard to the ability of the retrieved references to directly address the clinical question as follows: which prophylactic technique when considered with or without surgery will consistently reduce or eliminate the recurrence of clinical signs associated with Hansen’s type I intervertebral disc disease. All studies were compared and evaluated with regard to study design, technique utilized, short and long-term outcome, and evidence classification.An online bibliographical search was performed in PubMed using the full search term of “canine intervertebral disc disease and recurrence” resulted in 20 total sources, and of those sources 13 contained information pertaining to the clinical question. The same search term when used in the VIN search engine under the classification of journal abstracts resulted in 43 total results with 18 applicable resources. In review of both searches, 13 resources were listed in both searches. Of the 18 obtained by the VIN search 14 were available in the English language. No resources were included in class I level of evidence, and only one was considered as class II level of evidence. As for the remaining studies, three results were classified as class III studies, and the remaining reports were classified as class IV level of evidence.Although direct extrapolation of the evidence provided by the search to the clinical scenario is not possible, this review will hopefully provide the basis for development of a randomized controlled study to provide for a clear need in evidence for prevention of intervertebral disc extrusion in dogs.

Imaging is integral in the diagnosis of canine intervertebral disc disease (IVDD) and in differentiating subtypes of intervertebral disc herniation (IVDH). These include intervertebral disc extrusion (IVDE), intervertebral disc protrusion (IVDP) and more recently recognized forms such as acute non-compressive nucleus pulposus extrusion (ANNPE), hydrated nucleus pulposus extrusion (HNPE), and intradural/intramedullary intervertebral disc extrusion (IIVDE). Many imaging techniques have been described in dogs with roles for survey radiographs, myelography, computed tomography (CT), and magnetic resonance imaging (MRI). Given how common IVDH is in dogs, a thorough understanding of the indications and limitations for each imaging modality to aid in diagnosis, treatment planning and prognosis is essential to successful case management. While radiographs can provide useful information, especially for identifying intervertebral disc degeneration or calcification, there are notable limitations. Myelography addresses some of the constraints of survey radiographs but has largely been supplanted by cross-sectional imaging. Computed tomography with or without myelography and MRI is currently utilized most widely and have become the focus of most contemporary studies on this subject. Novel advanced imaging applications are being explored in dogs but are not yet routinely performed in clinical patients. The following review will provide a comprehensive overview on common imaging modalities reported to aid in the diagnosis of IVDH including IVDE, IVDP, ANNPE, HNPE, and IIVDE. The review focuses primarily on canine IVDH due to its frequency and vast literature as opposed to feline IVDH.

ABSTRACT: The objective of this study was to verify the clinical recovery of dogs that underwent ventral slot surgical decompression with lateralized compressions of the cervical spinal cord caused by intervertebral disc disease (IVDD). Twenty patients were selected in different degrees of neurological dysfunction with definitive diagnosis of lateralized compression by cervical IVDD. Postoperative clinical recovery was assessed in patients who had undergone at least two months of the surgical procedure. There was a satisfactory recovery in 19 dogs (95%) and unsatisfactory recovery in another (5%), showing a significant clinical improvement (p<0.05) in the use of this technique in lateralized compression cases. The ventral slot promotes satisfactory clinical recovery of dogs with lateralized compression of the spinal cord caused by cervical IVDD and may be indicated as a surgical alternative.

Abstract Objective The aim of this study was to determine if either the rate of onset of clinical signs or duration from initial clinical signs to surgical decompression affected the overall quality or duration of recovery in dogs with intervertebral disc extrusion. Study Design This was a retrospective case series of 131 client owned dogs. Medical records of dogs surgically treated with hemilaminectomy for intervertebral disc extrusion between January 2016 and December 2017 were reviewed for signalment, neurological grade at presentation, rate of onset and duration of clinical signs and surgical variables. These variables were analysed to determine their effect on return of pain sensation, urinary continence and ambulation. Results Duration of clinical signs prior to surgery and rate of onset of signs did not correlate with return of pain sensation, urinary continence or ambulation. Preoperative neurological grade was the main variable that was found to be associated with outcome. Conclusions Delay from initial clinical signs of intervertebral disc extrusion to surgery is unlikely to affect the ultimate outcome or the length of time for a dog to regain pain sensation, urinary continence or ambulation. The rate of onset of signs likewise does not influence these outcomes.

Abstract Background Calvarial Ewing tumor is a relatively rare differential among bony neoplasms. We present our experience of managing primary calvarial Ewing sarcoma (EWS), highlighting their clinical and radiological findings. Method In a retrospective analysis, we evaluated our 12-year database for pathologically proven EWS. A literature search was conducted for the comparative presentation and update on the management and outcome. Result From January 2008 to December 2020, we managed eight patients (male:female = 5:3; age range 6 months to 19 years, mean 11.5 years) harboring primary calvarial EWS. All cases underwent wide local excision; two patients required intradural tumor resection, while one required rotation flap for scalp reconstruction. Mean hospital stay was 8 days. All patients received adjuvant chemo- and radiotherapy. Three patients remained asymptomatic at 5 years of follow-up, while two patients died. Conclusion Primary calvarial EWS is a rare entity. It usually affects patients in the first two decades of life. These tumors can be purely intracranial, causing raised intracranial pressure symptoms, which may exhibit rapidly enlarging subgaleal tumors with only cosmetic deformities or symptoms of both. Radical excision followed by adjuvant therapy may offer a favorable long-term outcome.

AbstractTo characterize changes in intraocular pressure (IOP) and IOP-lowering medications through up to 2 years of follow-up in patients undergoing combined phacoemulsification and excisional goniotomy with the Kahook Dual Blade (phaco-KDB), with simultaneous goniosynechialysis in cases of angle-closure glaucoma. Prospective, non-comparative, interventional case series. Consecutive patients with medically-treated glaucoma and visually-significant cataract underwent combined surgery. Analysis was conducted on open-angle (OAG) and angle-closure (ACG) glaucoma groups separately. Thirty-seven patients with OAG (24 with primary OAG and 13 with pseudoexfoliation glaucoma) and 11 with ACG were enrolled. In OAG eyes, mean (standard error) baseline IOP was 21.1 (0.9) mmHg and through 24 months of follow-up was reduced by 6.4–7.7 mmHg (24.6–32.1%; p ≤ 0.0001 at all time points). In ACG eyes, mean baseline IOP was 20.8 (1.6) mmHg and was reduced by 6.1–8.77 mmHg (23.4–39.0%; p ≤ 0.0353). Mean medications were reduced by 61.9–89.1% (p ≤ 0.0001) in OAG eyes and by 56.3–87.3% (p ≤ 0.0004) in ACG eyes. Phaco-KDB significantly lowered IOP ~ 30% and medications by > 50% through 24 months. This combined procedure provides meaningful long-term reductions in IOP and need for IOP-lowering medication and does not adversely affect visual rehabilitation in eyes with cataract and glaucoma.

AbstractA number of authors have suggested that surgery for suspected perilymph fistula is effective in preventing deterioration of hearing and in improving hearing in some cases in the short term. We present long-term hearing outcome data from 35 children who underwent exploration for presumed perilymph fistula at The Children's Hospital, Sydney, Australia, between 1985 and 1992.Methods:The pre-operative audiological data (mean of 500, 1000, 2000 and 4000 Hz results) were compared with the most recently available data (range two to 15 years) and the six-month post-operative data.Results:The short-term results showed no significant change in hearing at six months, with a subsequent, statistically significant progression of hearing loss in both operated and non-operated ears (Wilcoxon signed rank test: operated ear, p < 0.017; non-operated ear, p < 0.009).Conclusion:In this case series, exploratory surgery for correction of suspected perilymph fistula did not prevent progression of long-term hearing loss.
