Conservative Versus Surgical Management of Gastrointestinal Linear Foreign Bodies in the Cat     

ANTHONY W. P. BASHER BVetMed  MRCVS  J. DAVID FOWLER DVM  MVSC 《Veterinary surgery : VS》1987,16(2):135-138

Twenty-four cases of gastrointestinal linear foreign bodies (LFB) in cats were reviewed. Nine cats were successfully managed conservatively, with passage of the LFB occurring 1 to 3 days after presentation. Ten cats that were initially managed conservatively were subsequently treated surgically. The decision to operate was based on worsening of clinical signs and failure to pass the LFB. Five cats were initially treated surgically. The cats that were managed successfully via conservative treatment had a shorter duration of clinical signs before presentation, decreased incidence of abdominal pain and palpable intestinal plication, and less severe hematologic abnormalities. Radiographic signs were of little benefit in deciding whether to treat the cats conservatively or surgically. None of the cats died.  相似文献   

Modified Lateral Orbitotomy for Removal of Orbital Neoplasms in Two Dogs   总被引：1，自引：0，他引：1  

BRIAN C. GILGER dvm. MS.    R. DAVID WHITLEY DVM  MS.  SUSAN A. MCLAUGHLIN dvm  MS 《Veterinary surgery : VS》1994,23(1):53-58

A simplified lateral orbitotomy is described that decreases surgical time and lessens tissue dissection, yet maintains the exposure to the orbit provided by other orbitotomy techniques. The approach involves cutting the orbital ligament, incising the temporalis aponeurosis from the dorsal zygomatic arch, making parallel zygomatic arch osteotomies, and reflecting the zygomatic arch ventrally. Closure of the wound involves wiring the zygomatic arch back into place. This orbitotomy procedure provides excellent exposure for removal or biopsy of orbital masses. The use of this technique for surgical excision of orbital masses in two dogs, one with an adenoma of the third eyelid gland and one with an orbital fibrosarcoma, and their subsequent management is described.  相似文献

Inactivation of canine parvovirus by disinfectants and heat     

DAVID McGAVING 《The Journal of small animal practice》1987,28(6):523-535

The resistance of canine parvovirus (CPV) to inactivation by chemical and thermal means was investigated. CPV with and without extraneous protein was tested against 15 commonly used disinfectants at room temperature. The titres of CPV remaining after 5 minutes disinfection time were greater than or equal to those remaining after 30 minutes regardless of the presence or absence of protein. Disinfection of CPV was accomplished more quickly and at lower concentrations of disinfectants when extraneous protein was absent. Halogen compounds, aldehydes and sodium hydroxide were the most acceptable CPV disinfectants. The presence of protein interfered with the two most frequently recommended CPV disinfectants—sodium hypo-chlorite and formaldehyde. The resistance of CPV to inactivation by heat depended on the temperature and the duration of heating. Boiling (100°C) rapidly inactivated CPV. The virus was more resistant to lower temperatures. Detectable infectivity remained after 7 hours at 80°C and 72 hours at 56°C. At both 37°C and room temperature there was no significant change in infectivity titres over 72 hours.  相似文献   

A Modified Cloward''s Technique for Arthrodesis of the Normal Metacarpophalangeal Joint in the Horse     

GREGORY R. CRAWLEY DVM  MS    BARRIE D. GRANT DVM  MS  DipiomateACVs    KARL K. WHITE DVM  DipiomateACVs    DAVID D. BARBEE DVM  MS  DiplomateACVR    ANTHONY M. GALLINA DVM  PhD  MARC H. RATZLAFF DVM  PhD 《Veterinary surgery : VS》1988,17(3):117-127

A modified Cloward's technique was performed for arthrodesis of one metacarpophalangeal (MCP) joint in eight horses. Dorsal arthrotomies were performed medial and lateral to the common digital extensor tendon and two 16 mm holes were drilled through the joint. A perforated cylindrical stainless steel basket filled with cancellous bone was impacted into each hole. The limbs were supported in casts for 8 weeks. The joints were examined and radiographed at 4 weeks, 8 weeks, 6 months, and 10 months. One horse was euthanatized at week 14 to assess the progress of the arthrodesis. In the other seven horses, there was clinical fusion at month 6. Dynamographic evaluations were performed 11 months after surgery at the walk and trot. The maximum vertical forces exerted during weight bearing by treated and control limbs were compared. No difference was detected at the walk; however, a significant difference was present at the trot (p less than 0.05). It was calculated that at the trot the horses placed 90% as much force on the treated limb as on the control limb. Eleven months after surgery, the baskets contained compact and cancellous bone. Ingrowth of bone occurred through all openings, completely filling the baskets and fusing the joints.  相似文献   

Magnetic resonance imaging in two dogs with central nervous system disease     

DAVID L. PANCIERA  IAN D. DUNCAN  ALBEE MESSING  JOHN E. RUSH  PATRICK A. TURSKI† 《The Journal of small animal practice》1987,28(7):587-596

Accurate localization of the lesions in two dogs with progressive neurological disease was demonstrated with magnetic resonance imaging (MRI). The first dog had unilateral cerebellar signs with associated paradoxical vestibular symptoms. The CSF tap and clinical localization suggested a right-sided cerebellar tumour and this was confirmed with MRI scanning. The second dog had predominantly asymmetrical fore-brain signs with circling, personality changes, seizures and contralateral proprioceptive deficits. CSF analysis suggested an inflammatory or neoplastic condition. MRI showed a diffuse oedematous lesion of the left cerebral hemisphere which corresponded exactly with the lesions seen at necropsy. The advantages of MRI over CT scans are discussed.  相似文献   

Pharmacokinetic Disposition of Cefazolin in Serum and Tissue during Canine Total Hip Replacement     

DANIEL C. RICHARDSON DVM  Diplomate ACVS    DAVID P. AUCOIN DVM    DAVID J. DEYOUNG DVM  Diplomate ACVS  ACVA    KRYSTYNA L. TYCZKOWSKA PhD  BONNIE A. DeYOUNG 《Veterinary surgery : VS》1992,21(1):1-4

Intraoperative cefazolin concentrations were measured in serum, joint capsule, cancellous bone of the acetabulum, and proximal cancellous bone of the femur in 15 dogs undergoing total hip replacement. Cefazolin (22 mg/kg intravenously [IV]) was administered every hour for three doses. The mean peak serum concentrations (+/- SEM) were 387.79 +/- 27.56 micrograms/mL, 521.71 +/- 28.00 micrograms/mL, and 542.20 +/- 30.91 micrograms/mL, respectively. Mean serum concentrations just before administration of doses 2 and 3 were 51.77 +/- 2.39 micrograms/mL, and 64.84 +/- 3.46 micrograms/mL, respectively. The mean cefazolin concentrations in the joint capsule, cancellous bone of the acetabulum, and cancellous bone of the femur were 34.71 +/- 2.50 micrograms/g, 28.70 +/- 7.40 micrograms/g, and 36.20 +/- 3.80 micrograms/g, respectively. The minimum inhibitory concentration of cefazolin for 90% of the common contaminants (MIC90) in this clinic is less than or equal to 2 micrograms/mL or per gram of tissue. Serum concentrations never fell below 15 times the MIC90 (lowest trough, 35.93 micrograms/mL), and the lowest tissue concentration (6.57 micrograms/mL in cancellous bone from the acetabulum) was still more than 3 times the MIC90. The mean tissue concentration was 15 times the MIC90.  相似文献   

A Retrospective Study of Inguinal Hernia in 35 Dogs   总被引：1，自引：0，他引：1

Inguinal hernia was associated with trauma in five dogs and was considered nontraumatic in 30 dogs. There were 11 males, 13 intact females, and six spayed females with nontraumatic inguinal hernia. Six dogs had bilateral hernias. Five dogs were younger than 4 months at the time of diagnosis. In 11 older dogs with nontraumatic inguinal hernia, the hernias were identified less than 7 days before surgical repair; in 14 older dogs, the hernias had been recognized for 1 to 60 months. Clinical signs in dogs without small intestinal incarceration were usually limited to a visible or palpable mass without pain or systemic illness. Hemiorrhaphy approaches included inguinal, midline with contralateral ring evaluation, and celiotomy with or without inguinal exposure. Fat and omentum were the most common hernial contents. Small intestine was within the hernias of 12 dogs. Six dogs had nonviable small intestine. Postoperative complications included two incisional infections, one incisional dehiscence, two cases of peritonitis and sepsis associated with bowel leakage after intestinal resection and anastomosis, and one hernia recurrence. The overall prevalence of postoperative complications was 17%, and the mortality rate was 3%. Vomiting for 2 to 6 days was predictive of nonviable small intestine. Dogs younger than 2 years were at 11 times greater risk for nonviable small intestine than dogs older than 2 years. Four of five dogs with nontraumatic inguinal hernia and nonviable small intestine were intact males, whereas none of 13 intact females were affected. Only one of 14 dogs with longstanding hernias had nonviable small intestine.  相似文献   

Arthroscopy of the Coxofemoral Joint of Foals     

CLIFFORD M. HONNAS dvm  Diplomate acvs    DAVID T. ZAMOS vmd  TROY S. FORD DVM  Diplomate ACVS 《Veterinary surgery : VS》1993,22(2):115-121

An arthroscopic procedure for examination of the coxofemoral joint was developed in nine foals (four cadavers, five anesthetized) to determine if access was sufficient for evaluation and surgical treatment of intra-articular lesions. The joint was distended and the arthroscope inserted through the notch (incisura trochanterica) between the cranial and caudal parts of the greater trochanter. This portal allowed examination of the cranial, lateral, and caudal aspects of the joint. Mechanical distraction of the joint through an instrument portal located 2 to 4 cm cranial and 1 to 2 cm ventral to the arthroscope portal allowed examination of the ligament of the head of the femur, the femoral head, and articular and nonarticular surfaces of the acetabulum. Adduction and rotation of the limb improved visualization of the craniomedial and caudomedial portions of the femoral head. Traction applied to the distal limb allowed visualization of the same structures that were observed when mechanical distraction was used. Traction also created space for placement of surgical instruments into the joint through the instrument portal. Access to most regions of the joint was adequate, but access to the caudal and medial aspects of the joint was limited. Three foals were killed while they were anesthetized, and their coxofemoral joints were dissected. Two foals were allowed to recover from anesthesia and were observed for 30 days after surgery. One foal was mildly lame for 2 days after surgery. The other foal was not lame after surgery. The incisions healed, and the coxofemoral joints were radiographically normal by postoperative day 30.  相似文献
