The clinical results of 39 consecutive ear ablations (in 28 dogs and three cats) performed over a 15-year period were reviewed. Indications for ear canal ablation included hyperplastic tissue stenosis of the horizontal ear canal (23), failed lateral ear resections (13), and horizontal ear canal neoplasms (3). Ear ablation was successful in alleviating persistent signs of otitis in eight of 15 dogs with horizontal ear canal stenosis due to hyperplastic tissue, seven of 10 dogs with unsuccessful lateral ear resections, and two of five animals (three cats and two dogs) with horizontal ear canal neoplasms (follow-up time periods greater than 5 months). Surgical complications occurred following 82% of the ablations; wound infections (41%) and facial nerve damage (36%) were most common. Local wound and antibiotic therapy successfully treated prolonged drainage following ablation in five of nine dogs. Bulla osteotomy and drainage were successful in the treatment of three dogs (four ears) that were unresponsive to medical therapy with postoperative ear fistula following ablation, one of two dogs with prolonged ear drainage following ablation for failed lateral ear resection, and one dog with recurrence of signs of inner ear disease following ablation (follow-up period, 1 month to 4 years; mean, 3.4 years). Facial nerve damage caused by ablation was transient in nine of 14 ears, with most deficits returning to normal within 2 weeks.  相似文献   

Holding Power of Orthopedic Screws Comparison of Self-tapped and Pre-tapped Screws in Foal Bone     

JOHN V. YOVICH bsc  bvms  A. S. TURNER bvsc  ms  Diplomateacvs  F. W. SMITH bsme  msme  PhD D. M. DAVIS bs   《Veterinary surgery : VS》1986,15(1):55-59

Comparison was made of the holding power of orthopedic screws inserted self-tapped or after pre-tapping in foal bone. Third metacarpal and metatarsal bones were used. Comparative trials were made between screws inserted at the same site in the corresponding bones from the contralateral limbs of the same foal. A MTS servohydraulic tensile testing machine was used to perform screw pullouts at a displacement rate of 19 mm/sec. The 5.5 mm cortical screws had significantly greater holding power than 6.5 mm cancellous screws when both were inserted self-tapped (p = 0.0056). Pre-tapped insertion of 5.5 mm screws produced a significantly greater holding power than self-tapped insertion of 5.5 mm screws (p = 0.018). Pre-tapped insertion of 6.5 mm screws produced a significantly greater holding power than self-tapped insertion of 6.5 mm screws (p = 0.0000). In internal fixation of fractures in foals, insertion of 5.5 mm and 6.5 mm screws pre-tapped in metaphyseal bone is recommended because it produces greater holding power than self-tapped insertion.  相似文献   

Partial Invagination of the Canine Stomach for Treatment of Infarction of the Gastric Wall     

DOUGLAS M. MacCOY  dvm  Diplomateacvm  STEPHEN K. KNELLER dvm  Diplomateacvr  JOHN P. SUNDBERG dvm  PhD  Dipiomateacvp JOSEPH HARARI ms  dvm 《Veterinary surgery : VS》1986,15(3):237-245

A technique was evaluated for the management of infarction of a portion of the canine gastric fundus and body by invagination of the compromised gastric wall with a double layer of inverting sutures. Two methods of potentially producing vascular compromise of the gastic wall were developed and studied. In the first method (ten dogs plus three control dogs), the first three short gastric arteries and veins were ligated and divided; vascular compromise was not produced. In the second method (eight dogs), an area of the gastric fundus was isolated by a strangulating suture in addition to the division of the short gastric vessels; this method did produce vascular compromise. The invagination procedure caused melena for several days in four dogs. Complete healing of the gastric wall had not occurred at 2 weeks.  相似文献   

The Effect of Long-Term Bone Plate Application for Fixation of Radial Fractures in Dogs   总被引：1，自引：0，他引：1  

JOSEPH C. GLENNON VMD    JAMES A. FLANDERS DVM  Diplomate ACVS    KATHY A. BECK DVM  Diplomate ACVR    ERIC J. TROTTER DVM  Diplomate ACVS  HOLLIS N. ERB dvm  PhD 《Veterinary surgery : VS》1994,23(1):40-47

This study was divided into two phases. In the in vitro phase, a stainless steel bone plate was applied to the cranial surface of the radius in 14 canine limbs. The effect of the presence of a bone plate on bone density analysis using radiographic photodensitometry (RP) was evaluated by comparing the density measurement of the unplated limb to the density measurement of the plated limb. The optical density of the plated bones was 12% greater than that of the unplated bones. This information was used as a correction factor for the in vivo study. In the in vivo phase, 23 dogs with radial and ulnar fractures were examined for complications associated with the long-term application of a stainless steel plate applied to the cranial surface of the radius. In 14 dogs, RP analysis was used to compare the plated limb with the normal, contralateral limb. No significant differences in radial cortical bone density existed between the plated limb and the contralateral limb after taking into account the effect a bone plate had on photodensitometry readings. There was no significant correlation between the change in radial cortical density and the duration of bone plate application, suggesting that a steady state between bone loss and bone production occurs after long-term plate fixation of the fractured canine radius. The majority (87%) of the dogs with a plate applied to the radius greater than 1 year had normal limb usage when standing, walking, or running.  相似文献   

Excision of Neoplasms of the Bovine Lower Eyelid by H-Blepharoplasty

Neoplasms of the lower eyelid in 14 cattle were treated by wide surgical excision and H-blepharoplasty. Healing was by first intention, and cosmetic results were satisfactory in all cases. Lid function was satisfactory in 12 cattle, and there was no evidence of recurrence after at least 6 months in 12 cattle. This therapy can be recommended for large infiltrative masses on the lower lid if there is no evidence of bony involvement, metastasis, or involvement of both puncta at the medial canthus.  相似文献   

Vertical habitat utilization by large pelagic animals: a quantitative framework and numerical method for use with pop-up satellite tag data     

JIANGANG LUO  ERIC D. PRINCE  C. PHILLIP GOODYEAR  BRIAN E. LUCKHURST  JOSEPH E. SERAFY 《Fisheries Oceanography》2006,15(3):208-229

A quantitative framework and numerical methodology were developed to characterize vertical habitat utilization by large pelagic animals and to estimate the probability of their capture by certain types of fishing gear. Described are the steps involved to build ‘vertical habitat envelopes’ from data recovered from an electronically tagged blue marlin (Makaira nigricans) as well as from a longline fishing gear experiment employing temperature–depth recording devices. The resulting vertical habitat envelopes, which integrate depth and temperature preferences of tagged fish, are conducive for comparative studies of animal behavior and for calculation (and visualization) of degrees of overlap – be it among individuals, species or fishing gear. Results of a computer simulation evaluation indicated our numerical procedure to be reliable for estimating vertical habitat use from data summaries. The approach appears to have utility for examining pelagic longline fishing impacts on both target and non‐target species and could point to ways of reducing bycatch via modification of fishing strategy or gear configuration.  相似文献   

Species associations of epipelagic nekton of the North Pacific Ocean, 1978–1993     

WILLIAM G. PEARCY  JOSEPH P. FISHER  GEN ANMA  TOSHIMI MEGURO 《Fisheries Oceanography》1996,5(1):1-20

Strong latitudinal gradients in species composition were revealed by two-way indicator species analysis (TWINSPAN) and detrended correspondence analysis (DCA) of 41 species of epipelagic fishes and squids in 513 gillnet collections by research vessels of Hokkaido University over a huge area of the northern North Pacific during the summers of 1978–1993. Salmonids inhabited northern subarctic water and skipjack tuna (Euthynnus pelamis) and flying squid (Ommastrephes bartrami) inhabited the region of the Subarctic Boundary, but distinct boundaries between species groups and sample groups were lacking, largely because abundant species, such as Pacific saury (Cololabis saira) and Pacific pomfret (Brama japonica), migrated across most of this region during the summer. Longitudinal differences were not pronounced, but some species, including Japanese sardine (Sardinops melanostictus) and Japanese anchovy (Engraulis japonicus), were only found in the western Pacific. Pacific saury was more common in the western Pacific, whereas sockeye salmon (Oncorhynchus nerka) was concentrated in the eastern Pacific. Interannual fluctuations in the latitude of species groups were most closely correlated with changes in sea surface temperatures. In the western Pacific, 1982, 1983, 1985, 1987-88, and 1992-93 were cool years when subarctic and transitional assemblages were found farther to the south than other years. Temperature and salinity at various depths were highly correlated with each other and with first-axis DCA ordinations scores. Long-term trends in community structure were not apparent during the 1.6 decades.  相似文献   

Excision of Cutaneous Tumors in the Horse Using Histologic Guidance     

R. ADAMS ma  dvm    M. B. CALDERWOOD-MAYS vmd  PhD  L. C. PEYTON dvm  ms 《Veterinary surgery : VS》1988,17(5):241-245

A highly successful surgical technique for removing cutaneous tumors in humans was used in seven horses with cutaneous squamous cell carcinoma (n = 3) or sarcoid (n = 4). In humans, the complete underside of the tumor is evaluated histologically by processing horizontal sections from the tumor base, and orientation between the wound surface and the undersurface of the excised tumor is maintained by mapping both surfaces. The technique ensures that small foci of residual tumor can be located accurately and removed. Based on our experience, three modifications of the human technique are suggested for its use in horses. The equine patient should be placed under general anesthesia rather than using local anesthesia if the tumor is in a difficult position for standing surgery or the patient is uncooperative; useful information can be obtained from tissue processed in buffered formalin if frozen sections are not available; and optimal tumor size for this procedure is no larger than 3 x 2 cm.  相似文献   

Open Abdominal Drainage in the Treatment of Generalized Peritonitis in 25 Dogs and Cats   总被引：1，自引：0，他引：1  

JOEL M. WOOLFSON dvm  MARY L. DULISCH dvm  ms  Dipiomateacvs 《Veterinary surgery : VS》1986,15(1):27-32

The case records of 20 dogs and 5 cats that were managed by open peritoneal drainage for generalized peritonitis were reviewed. Although the underlying causes varied, diffuse septic peritonitis was present in all animals. The abdominal incision was closed loosely at the time of the first surgical procedure, and a sterile abdominal wrap was maintained throughout the postoperative period. The abdomen was closed completely in a second surgical procedure performed 2 to 9 days later.
The overall mortality rate was 48%. Most deaths occurred before secondary closure of the abdomen was performed. Complications of open peritoneal drainage were hypopro-teinemia and nosocomial contamination.  相似文献   

Silicone Elastomer Sling for Fecal Incontinence in Dogs     

PAUL W. DEAN DVM    DENNIS P. O''BRIEN DVM  PhD  Diplomateacvim    MARGARET A. M. TURK DVM  PhD  Diplomateacvp  M. JOSEPH BOJRAB DVM  MS  PhD  Diplomateacvs 《Veterinary surgery : VS》1988,17(6):304-310

Fecal incontinence was created by bilateral pudendal neurectomy in 12 dogs. In six dogs, the fecal incontinence was treated by implantation of a polyester-impregnated silicone elastomer sling to form an artificial external anal sphincter. Six dogs underwent the same operative procedure without the implant to serve as controls. Five dogs regained total continence and one dog regained partial continence after implantation of the sling. Four control dogs remained incontinent and two control dogs regained partial continence. The difference between the dogs with slings and the controls was statistically significant (P less than 0.01). The only complication was infection in one dog, which was treated successfully. Histologic reaction to the implant was confined to a zone of fibrosis 1 to 3 mm surrounding the implant. The sling was well tolerated clinically and appeared to offer a successful method for correction of fecal incontinence in dogs.  相似文献
