Mielopatia estenótica cervical em equídeos: um estudo retrospectivo (2006 - 2016).

Abstract

Cervical stenotic myelopathy in equids: a retrospective study (2006 - 2016). Cervical stenotic myelopathy (CSM) is a cervical vertebral alteration, resulting in stenosis of the spinal canal, compression of the spinal cord and damage to the tracts of the spinal Cord nerves. CSM can be classified as dynamic stenosis (C3-C4 and C4-C5), affecting young animals between eight and eighteen months, and static stenosis (C5-C6 and C6-C7), being present in animals with one to four years. The objective of this study was to know the occurrence of CSM and to draw an epidemiological and clinical profile of the cases at the Veterinary Hospital (HV) of the Federal University of Campina Grande (UFCG). In addition, this work proposes a flowchart for the diagnosis of CSM in the field, based mainly on the symptomatology. In the present study, it was observed that of the 2,949 equidae treated in the period of ten years (2006 to 2016), 12 (0.4%) animals presented some cervical pathology. Of these, five (41.3%) were presumptively diagnosed with CSM. According to the epidemiological data, it is notable in the sample that the oldest animals between eight and twelve years old stood out, being affected three (60%) horses; the most affected species were equines in a total of four (80%) horses and one (20%) asinine; among the affected races, the quarter of mile presented three (60%) affected animals and the without race defined animals (SRD) presented two (40%); males were prominent among females, four (80%) and one (20%) were respectively diseased; in relation to fitness , four sport horses presented a rate of 80%, while only one (20%) work-related animal for the affected one; in this study of the five diseased animals, only one (20%) was euthanized. Therefore, CSM is a disease of low casuistry, but present in the routine, of uncertain cure, and complex diagnosis.
