Total and Partial Orbitectomy for the Treatment of Periorbital Tumors in 24 Dogs and 6 Cats: A Retrospective Study 总被引:1,自引:0,他引:1
M. G. O'BRIEN DVM Diplomate ACVS S. J. WITHROW DVM Diplomate ACVS ACVIM R. C. STRAW BVSc Diplomate ACVS B. E. POWERS DVM PhD Diplomate ACVP J. K. KIRPENSTEIJN DVM Diplomate ACVS ECVS 《Veterinary surgery : VS》1996,25(6):471-479
Total or partial orbitectomy were used to treat 24 dogs and six cats with invasive periorbital tumors. The surgical procedure and clinical results were evaluated in this retrospective study. The most common types of tumors treated in this series of patients were multilobular osteochondrosarcoma and squamous cell carcinoma. Two patients died of cardiopulmonary arrest within 24 hours after surgery. One patient developed neurological signs after total orbitectomy that resolved with conservative therapy. Minor complications, which included infection, strabismus, and conjunctivitis, occurred in seven patients. Regrowth of tumor in the periorbital region occurred in 11 patients (36.7%). Tumor resection by orbitectomy provided local disease-free interval of more than 1 year in more than 50% of patients. Survival rate for the first year was 70.4% in this series of patients as determined by life table analysis. Orbitectomy requires detailed knowledge of regional anatomy and experience with performing a combination of surgical procedures. Preoperative diagnostic tests should include imaging techniques to define the extent of the disease. When performed properly, orbitectomy is a valuable procedure that can be used to effectively treat invasive tumors of the orbit. 相似文献

Osteochondral defects of the lateral trochlear ridge of the distal femur were identified in 15 joints of 10 horses. Lesions were bilateral in five horses and unilateral in five horses. Thirteen of these 15 defects were treated by curettage through a craniolateral femoropatellar arthrotomy. Subcutaneous seroma formation and partial skin dehiscence occurred in nine stifles. Lameness attributable to the stifle joint was no longer apparent at 6 and 12 months after surgery. The normal subchondral bony contour of the lateral trochlear ridge was altered in all joints after surgery. The subchondral bone was uniformly increased in density in all joints, and six lateral trochlear ridges had small focal radiolucent regions within the subchondral bone, which suggested that complete removal of the original lesion had not been achieved. Healing of the surgical site between 2 weeks and 14 months was evaluated in four joints. Granulation tissue from mesenchymal elements in subchondral marrow spaces gradually filled the defects with fibrocartilage. 相似文献

Central Nervous System Infection Associated With Anaerobic Bacteria in Two Dogs and Two Cats 总被引:1,自引:0,他引:1
Steven W. Dow DVM MS Richard A. LeCouteur BVSc PhD Rosemary A. Henik DVM MS Robert L. Jones DVM PhD Mary L. Poss MS DVM 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1988,2(4):171-176
Central nervous system (CNS) infection caused by anaerobic bacteria (including Bacteroides, Fusobacterium, Peptostreptococcus, and Eubacterium) was diagnosed in two dogs and two cats. In one dog there was extensive meningomyeloencephalitis, presumably the result of hematogenous spread of bacteria from lung abscesses and bacterial endocarditis. Subdural empyema of unknown origin was found in a second dog and two cats. Clinical signs in all four animals included mental depression and focal neurologic deficits, without fever. 相似文献

Splenomegaly in Dogs 总被引:2,自引:1,他引:1
K. A. Johnson MVSc PhD B. E. Powers DVM PhD S. J. Withrow DVM M. J. Sheetz AHT C. R. Curtis PhD R. H. Wrigley BVSc MS 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1989,3(3):160-166
Splenomegaly confirmed by surgery or necropsy in 100 dogs was diagnosed histologically as benign neoplasia (n = 1), primary splenic malignancy (n = 59), neoplastic metastases (n = 6), and nonneoplastic disease (n = 34). Dogs with known systemic disease, such as lymphoma and mast cell tumor, that caused splenomegaly were not included in the study. Hemangiosarcoma was the most common splenic disease (43 cases). Overall mean age of the dogs was 10.7 years, the most common breed was German Shepherd dog, and 72 of the dogs weighed more than 21 kg. Dogs with anemia, nucleated red blood cells, abnormal red blood cell morphology, or splenic rupture had a significantly greater chance of having splenic neoplasia (P less than 0.002). A multivariable logistic regression analysis found that the presence of anemia and splenic rupture in dogs with splenomegaly was up to 69% accurate in predicting presence of splenic neoplasia. After splenectomy, the median survival time of dogs with splenic neoplasia was 13 weeks. For dogs with nonneoplastic splenomegaly it was at least 36 weeks. 相似文献

The equine carpal joint was used to evaluate arthroscopic diagnosis of lesions created in joints obtained from horses euthanized for reasons other than lameness. Full-thickness articular defects were made in 13 sites within the antebrachiocarpal joint and middle carpal joint approximating those found in diseased carpal joints. Arthroscopic evaluation of the lesions included location, depth, and size of the defects. The joints were subsequently examined grossly. Results showed that, when compared to gross evaluation, arthroscopy is capable of accurately identifying subtle changes in articular cartilage and bone. A statistically significant increase in error rate was found for lesions at the medial aspect of the proximal radial carpal bone. Other sites with limited arthroscopic access were the proximal ulnar carpal bone, the proximal fourth carpal bone, and the distal intermediate carpal bone. The accuracy of arthroscopic identification of lesions improved significantly during the study as experience with the technique was gained. 相似文献

Hiatal Hernia Repair by Restoration and Stabilization of Normal Anatomy An Evaluation in Four Dogs and One Cat 总被引:1,自引:0,他引:1
CAROLINE PRYMAK BVSc H. MARK SAUNDERS VMD DiplomateACVR ROBERT J. WASHABAU VMD DipiomateACVIM 《Veterinary surgery : VS》1989,18(5):386-391
Clinical signs of esophageal hiatal hernia in four dogs and one cat included regurgitation, vomiting, hematemesis, hypersalivation, dysphagia, and dyspnea. Thoracic radiographs, esophagram, and fluoroscopy were used to demonstrate cranial displacement of the esophagogastric junction and part of the stomach through the esophageal hiatus. Other findings included megaesophagus, esophageal hypomotility, gastroesophageal reflux, and pneumonia. Medical therapy failed to resolve the clinical signs. Reduction in size of the esophageal hiatus, fixation of the esophagus to the diaphragmatic crus (esophagopexy), and a left fundic gastropexy were performed. Surgical results were considered good to excellent. 相似文献

Thermal Burns in Four Dogs during Anesthesia 总被引:1,自引:0,他引:1
COLIN I. DUNLOP BVSc DiplomateACVA DAVID A. DAUNT DVM STEVE C. HASKINS DVM MS DiplomateACVA 《Veterinary surgery : VS》1989,18(3):242-246
Thermal burns occurred in four anesthetized dogs as a result of using latex surgical gloves filled with warm water to treat hypothermia. The burns were on relatively hairless skin that had been in contact with the gloves. Small containers full of warm water are a relatively inefficient source of heat, but if the temperature of the water exceeds 45 degrees C and the container contacts the animal's skin, thermal injury can result. 相似文献

The greater omentum was used to aid in the reconstruction of nonhealing wounds in five cats. In each cat the cause of the nonhealing wound could not be determined. A vascular omental pedicle was created at laparotomy by dividing the dorsal leaf of the omentum at its pancreatic attachments (four cats) or by dividing the ventral leaf at its gastric attachments (one cat). The pedicle was then passed through either the ventral or lateral body wall into the nonhealing wound via a subcutaneous tunnel. The wounds were closed over the omentum after local tissue mobilization. All the wounds healed uneventfully and have remained healed with a mean follow-up period of 2.5 years. Complications included intestinal herniation through a ventral midline exit hole (one cat), presumed abdominal fat herniation through a ventral abdominal exit hole (one cat) and seroma formation (one cat). All of the complications were treated successfully. The omentum should be considered a useful adjunct in the treatment of nonhealing wounds in cats. 相似文献

Forty-eight dogs with histologically confirmed appendicular osteosarcoma (OSA) entered a prospective clinical trial evaluating treatment with amputation and up to 4 doses of carboplatin given every 21 days. The median disease-free interval (DFI) was 257 days, with 31.2% of the dogs disease-free at 1 year. The median survival time was 321 days, with 35.4% of the dogs alive at 1 year. Dogs with proximal humeral OSA had shorter DFI (P = .016) and survival (P = .037) times than dogs with OSA at other locations. Dogs with lower body weights (40 kg) had longer DFI (P = .0056) and survival (P = .007) times than larger dogs. Survival times for dogs that received carboplatin were statistically longer than those previously reported for amputation alone (P < .001). DFI and survival times are similar to those previously reported for 2 to 4 doses of cisplatin. Carboplatin appears to be a well-tolerated chemotherapeutic drug that can be given safely every 21 days at a dose of 300 mg/m2 . Neutropenia was the dose-limiting toxicity in this study.
