摘要:

Equine cervical vertebral malformation may result in spinal cord compression that, until recently, has been treated medically. Two descriptions of dorsal laminectomy in the horse indicated the technique could be disastrous, even in the normal horse, and postoperative improvement was variable. In the technique described here, the horse is placed in an oblique lateral position with the neck ventroflexed. A dorsal midline incision is used to expose the cervical vertebrae. Following removal of the soft tissues overlying the dorsal laminae, a Funkquist type B laminectomy is performed. Ligamentum flavum scar tissue, articular facets, and joint capsule are trimmed if they are contributing to the spinal cord compression. The bony defect is filled with a nuchal fat graft, and the surgical site is drained for 4 to 5 days by a suction drainage apparatus. The technique is evaluated in two accompanying articles.

摘要:

Subtotal dorsal cervical laminectomy was performed on nine normal horses to evaluate positioning, refine the surgical technique, and assess the immediate and long‐term effects of this procedure in the horse. Funkquist type B laminectomies were performed at various levels from C3‐C4 to C6‐C7. Absorbable gelatin sponge or autogenous nuchal fat was placed over the exposed dura mater. Surgery times varied from 2 to 3 hours, and all horses recovered without complication. Rapid primary intention wound healing occurred, with two horses showing neck pain. All remained neurologically normal. The horses were euthanized 6 weeks, 3 months, or 6 months postoperatively. Myelograms performed just prior to euthanasia demonstrated normal or expanded dye column widths. Necropsy revealed that all surgical sites had healed well. The laminectomy membrane was soft and pliable and could be easily separated from the underlying dura mater when fat was used as interpositional material. When gelatin sponge was used, the laminectomy membrane was firmly bonded to the dura. Spinal cords at the level of laminectomy appeared normal and moved freely within the vertebral canal. Histological evaluation of the laminectomy sites and associated spinal cord revealed no abnormalities attributable to the surgery. It was concluded that dorsal cervical laminectomy can be performed in horses without untoward sequelae. The procedure may be useful for the treatment of equine cervical compressive myelopa

摘要:

Subtotal dorsal cervical laminectomy was used to relieve spinal cord compression due to cervical vertebral malformation in 16 horses. The majority were Thoroughbred or Quarter Horse males, 1 to 4 years old. The caudal cervical vertebrae were involved in all but two instances. A Funkquist type B laminectomy was performed and the defect filled with a free autogenous nuchal fat graft. All horses recovered from surgery without complication or deterioration in neurological status. Neurological improvement occurred in 12 cases, including six that became sound. Three horses fractured a vertebral articular process and were euthanized. A modification to the shape of the laminectomy was adopted to reduce this complication.

摘要:

Ventrodorsal radiographs of the hips of 12 dogs were obtained. Copies of the radiographs were circulated to eight people with instructions for measurement of the angle of inclination of the femoral head and neck by two methods. A high degree of interobserver variation was found with both methods of measuring the angle of inclination.

摘要:

Laryngeal paralysis was created in normal dogs by sectioning the recurrent laryngeal nerves. The dogs were treated with bilateral vocal fold resection and unilateral partial arytenoidectomy, and sacrificed from 6 hours to 28 days following surgery. Swallowing abnormalities were not found in any of the dogs. Healing by granulation‐epithelialization was complete by 14 day

摘要:

Partial laryngectomy, arytenoid disarticulation/lateralization, and arytenoidopexy were performed on cadavers from normal dogs. The change in glottic cross‐sectional area was calculated from photographs. Partial laryngectomy and unilateral lateralization resulted in a 70 to 80% increase in glottic area. Bilateral lateralization resulted in a significantly greater increase (180%

摘要:

Urinary drainage was maintained in six cats for 3 days using Stamey percutaneous suprapubic catheters. Necropsies were performed 7 to 9 hours after catheter removal in three cats and 5 days after catheter removal in three cats. The catheter tract in the bladders had sealed within 9 hours of catheter removal. Focal areas of hemorrhage were observed on gross examination. Histopathologic examination revealed focal areas of hemorrhage and inflammation.Throughout the study, the cats remained alert and had normal appetites and normal serum creatinine. All of the cats had gross hematuria that resolved within 24 to 48 hours of catheter insertion. Two cats developed bacteriuria.
