thoracic Vertebral Canal Stenosis associated with Vertebral arch anomalies in small brachycephalic screw tail dog breeds
Veterinary and Comparative Orthopaedics and Traumatology, 2021Co-Authors: Alessandro Conte, Steven De Decker, Marco Bernardini, Cristoforo Ricco, Sebastien Behr, Daniel Sanchezmasian, Guinio B Cherubini, Luisa De Risio, Rodrigo GutierrezquintanaAbstract:Objective The aim of this study was to describe clinical and imaging features of thoracic Vertebral Canal Stenosis secondary to the hypertrophy of the Vertebral lamina and articular processes in screw-tail brachycephalic dog breeds, to evaluate the prevalence of the malformation in a large group of screw-tail dog breeds and to determine if degree of Stenosis is associated with presence of neurological signs. Study Design This is a retrospective multicentric study. Materials and Methods Clinical records of 185 screw-tail brachycephalic dogs (French Bulldogs, English Bulldogs, Boston Terriers) and Pugs were reviewed. Ten dogs with neurological deficits secondary to thoracic Vertebral Canal Stenosis diagnosed on magnetic resonance imaging were identified (Group 1). Neurologically normal dogs (n = 175) of the same breeds underwent computed tomographic imaging of the thoracic Vertebral column for other medical reasons (Group 2). Cross-sectional measurements were used to calculate a stenotic ratio. Results Group 1 consisted of three French Bulldogs, six English Bulldogs and one Pug. Eight were males. Most dogs presented with progressive non-painful pelvic limbs ataxia and paresis. Twenty stenotic sites were identified with the most common being T4–T5. Three of ten dogs were treated surgically and all had a good long-term outcome. In Group 2, 33 of 175 dogs had one or more stenotic sites with the most common being T2–T3. The degree of the Stenosis was significantly higher in Group 1 (p = 0.019). A stenotic ratio of 0.56 had sensitivity and specificity of 67% to differentiate between dogs with and without neurological signs. Conclusion Cranial thoracic Vertebral Canal Stenosis is observed predominantly in young male Bulldogs, but not all stenoses are clinically relevant.

Radiographic Vertebral Canal and Vertebral body ratios in Doberman Pinschers with and without clinical signs of caudal cervical spondylomyelopathy.
American journal of veterinary research, 2011Co-Authors: Steven De Decker, Jimmy Saunders, Luc Duchateau, Pascaline Pey, Luc Van HamAbstract:Objective—To determine radiographic Vertebral ratio values representing Vertebral Canal Stenosis in Doberman Pinschers with and without clinical signs of caudal cervical spondylomyelopathy (CCSM). Animals—Doberman Pinschers with (n = 81) and without (39) signs of CCSM. Procedures—All dogs underwent lateral survey radiography of the cervical Vertebral column. Five specific measurements were made at C3 through C7, and from those data, 3 ratios were calculated and analyzed for use in diagnosis of CSSM: Canal height-to-Vertebral body height ratio (CBHR), Canal height-to-Vertebral body length ratio (CBLR), and caudal Vertebral Canal height-to-cranial Vertebral Canal height ratio (CCHR). The CBHR and CBLR were considered indicators of Vertebral Canal Stenosis, and CCHR described Vertebral Canal shape. Results—Compared with Doberman Pinschers without CCSM, mean CBHR and CBLR values were significantly smaller for Doberman Pinschers with CCSM; for CBHR, this difference was evident at each assessed vertebra. The CC...

comparison of magnetic resonance imaging with standing cervical radiographs for evaluation of Vertebral Canal Stenosis in equine cervical stenotic myelopathy
Equine Veterinary Journal, 2014Co-Authors: J G Janes, S M Reed, K S Garrett, K J Mcquerry, Anthony Pease, Neil M Williams, James N MacleodAbstract:Summary Reasons for performing study The sensitivity and specificity of lateral cervical radiographs to evaluate horses suspected of cervical stenotic myelopathy (CSM) are limited by the assessment being restricted to the sagittal plane. Objective To determine whether magnetic resonance imaging (MRI) allows for a more accurate identification of Stenosis than lateral cervical radiographs in horses with CSM. Study design Case control study. Methods Nineteen Thoroughbred horses with CSM (17 males, 2 females, age 6–50 months) were compared to 9 control Thoroughbreds (6 males, 3 females, age 9–67 months). Ante mortem, the subjects had neurological examinations and standing cervical radiographs with sagittal ratios calculated from C3 to C7. Intact cervical column MRI scans and histological examinations of the spinal cord were performed post mortem. Morphometric parameters were measured on the Vertebral Canal, spinal cord and interVertebral foramen. Results Radiographic cervical Canal height measurements categorised by standard minimal sagittal diameter intraVertebral and interVertebral ratios produced several false positive and false negative determinations of Canal Stenosis as defined by spinal cord histopathology. Post mortem MRI measurements of Canal area and cord Canal area ratio more accurately predicted sites of cord compression in CSM cases. No differences in spinal cord measurements were observed when comparing CSM to control horses, but each of the Vertebral Canal parameters achieved significance at multiple sites. Conclusions Vertebral Canal area and cord Canal area ratio are better parameters to predict the location of cervical Canal Stenosis compared to only the sagittal plane of Canal height. Additional visual planes and measurements obtained by MRI, specifically Vertebral Canal area and the cord Canal area ratio, will provide a more accurate method to identify regions of Canal Stenosis than lateral cervical radiographs. The development of MRI or computed tomography equipment capable of evaluating the cervical column of mature horses may substantially enhance evaluation of CSM patients.

Thoracic Vertebral Canal Stenosis in cats: clinical features, diagnostic imaging findings, treatment and outcome
'SAGE Publications', 2020Co-Authors: Gillespie S, De Decker SAbstract:Objectives The aim of this study was to describe the clinical features, diagnostic imaging findings, treatment and outcome in cats with thoracic Vertebral Canal Stenosis (TVCS). Methods Medical records and imaging studies of cats with TVCS were retrospectively reviewed. Outcome was acquired from patient records and from owners or referring veterinary surgeons via a telephone questionnaire. For each case, breed-, age- and sex-matched controls were identified with CT imaging of the thoracic Vertebral column. For each cat, Vertebral Canal height was determined at three levels for each thoracic vertebra. Vertebral Canal heights were compared between control cats of different breeds and between affected and control cats of the same breed. Results Nine TVCS cases were included. British Shorthairs and male neutered cats were over-represented (P
