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.  相似文献

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 days.  相似文献

Vulvovaginectomy and perineal urethrostomy were performed in three dogs with extensive neoplasms of the vulva and vagina. One benign tumor (fibroleiomyoma) and two malignant tumors (transitional cell carcinoma and anaplastic spindle cell sarcoma) were diagnosed. Survival times were 9 weeks to 10 months. Urinary continence was preserved in all three dogs. The procedure may be curative for benign tumors or malignant tumors that have not yet metastasized; it is a palliative procedure for advanced malignancies.  相似文献

Femoral neck and proximal epiphyseal lengths were measured in 37 femurs from 19 cadaver foals that were 1 day to 12 months old to determine the applicability of a human interfragmentary compression system to equine femoral capital physeal fractures. Because components of the implant system are available only in fixed sizes, its use was possible in foals older than 5 weeks of age, but not in younger foals. The 135 degree angle plate conformed best to the equine femur. Femoral capital physeal fractures were created surgically and repaired with the implant system in three foals. Fracture stability was evident clinically and radiographically in all three foals until euthanasia at month 3. At necropsy, the treated femurs were 4, 8, and 27 mm shorter than their mates. Epiphyseal viability was verified in all three foals by tetracycline deposition and new appositional bone growth comparable with that in the contralateral control epiphyses. The treated capital physis was open but reduced in thickness in one foal, disorganized in one foal, and closed in one foal. Fixation by compression with the implant system resulted in stability sufficient for fracture healing and maintenance of epiphyseal viability, although it was associated with reduced longitudinal femoral growth.  相似文献

The nasal cavities of 14 dogs and three cats were explored surgically using a ventral rhinotomy. The exposure achieved through this approach was considered to be equal to a dorsal rhinotomy. One animal died during the immediate postoperative period from perforation of a gastric ulcer. The other animals recovered well and had no significant complications. The long-term survival of the animals was consistent with previous reports for their diseases. Ventral rhinotomy is no more difficult than dorsal rhinotomy, has less patient morbidity and fewer postoperative complications, and is more cosmetically acceptable.  相似文献

Hollow viscus perforation and leakage were treated successfully in eight dogs by suturing the surface of a loop of healthy bowel over the leaking areas, forming a serosal patch. The technique also was employed in three dogs and one cat to reinforce areas of potential leakage in the urinary bladder, small intestine, and colon.
Healthy bowel serosa was used to seal perforations in both clean-contaminated and grossly infected visceral wounds. The serosal patch, with its muscular and submucosal reinforcing layers, resisted intraluminal pressure and proved successful in some animals where omental patching or wrapping had failed.  相似文献

Osteochondritis dissecans (OCD) and subchondral cyst-like lesions in 13 shoulders of 11 horses were treated arthroscopically by curettage and lavage. Lameness decreased in all 11 horses. Nine horses were sound, five of them athletically sound, after 5 to 20 months. Complications included the development of subchondral cyst-like lesions and signs of degenerative joint disease. Arthroscopic surgery of the equine shoulder can be done through two portals, one for the arthroscope and one for an instrument. A few hand instruments such as a probe, Ferris-Smith rongeurs, and small, large, and right-angled curettes are needed to debride most lesions. Motorized equipment can expedite the process.  相似文献

An 11-year-old, throughbred stallion was examined for a small, firm swelling on the right mandible. During the following 4 weeks, the swelling markedly increased in size. An adamantinoma was diagnosed on histopathologic examination. Surgical treatment was "enblock" resection of the tumor and associated mandible, cryosurgery, and stabilization with both internal and external orthopedic fixation devices. The horse recovered from surgery, and for the past year has been a useful breeding stallion.  相似文献

Medial patellar desmotomy was performed on one (treated) hindlimb, and a sham operation on the other (control) hindlimb, of 12 normal horses. The horses were examined for lameness before medial patellar desmotomy and at months 1, 2, and 3. The femoropatellar joints were examined radiographically and arthroscopically at month 3. All horses were lame on the treated limb at months 1, 2, or 3. Radiographic changes, including fragment formation at the distal aspect of the patella and bone production at the attachment of the middle patellar ligament on the patella, were present in 11 horses at month 3. Articular cartilage fibrillation or detachment was seen arthroscopically on the patellas of all treated limbs. In six horses, loosely attached fragments of bone and cartilage were removed arthroscopically from the distal aspect of the patella of the treated limb. The control limbs were clinically, radiographically, and arthroscopically normal throughout the study. Medial patellar desmotomy results in pathologic changes in the articular cartilage of the patella and adjacent soft tissues. Use of this surgical procedure should be reserved for persistent and confirmed cases of upward fixation of the patella.  相似文献
