RESUMO
Medical records of 144 small-breed dogs (< or =15 kg) and 46 medium- to large-breed dogs (>15 kg) with surgically confirmed, Hansen type I, cervical intervertebral disk extrusions were reviewed. The most common clinical presentation was cervical hyperesthesia. The most common sites affected were the second (C(2)) to third (C(3)) cervical intervertebral disk space in small-breed dogs and the sixth (C(6)) to seventh (C(7)) cervical intervertebral disk space in the larger dogs. Following surgery, 99% of the dogs had resolution of cervical hyperesthesia and were able to ambulate unassisted. Seven (4%) dogs required a second surgery; four of these were large-breed dogs.

The medical records of 10 cats diagnosed with intervertebral disk disease were reviewed. No apparent sex or breed predilection was found. The mean age of cats in the study was 9.8 years. Clinical signs included back pain, difficulty ambulating, and incontinence. Radiographs revealed narrowed disk spaces, mineralized intervertebral disks, and evidence of extradural compression on myelography or computed tomography. All intervertebral disk herniations occurred in the thoracolumbar spine, with a peak incidence at the fourth to fifth lumbar (L4-L5) intervertebral disk space. Eight cats had Hansen's type I intervertebral disk herniation. Surgery was performed in seven cats. All cats judged to have an excellent outcome had undergone surgical decompression.

Medical records of 62 large, nonchondrodystrophic dogs diagnosed with thoracolumbar intervertebral disk disease between March 1986 and February 1996 were reviewed. Fifty-seven (92%), primarily mixed-breed dogs (mean age, 6.6 years) had Hansen type I disease. Fifty-eight percent had acute onset. The interspace between the first (L1) and second (L2) lumbar vertebrae was affected most commonly. The outcomes of the 48 dogs available for follow-up after undergoing laminectomies were evaluated. Surgical success rate and mean time to walking for nonambulatory dogs with deep pain perception was 90% and seven weeks, respectively. Thirty-nine percent had residual deficits. Following surgery, 12% had recurrence of disk protrusion/extrusion at a different site.
