摘要:

Arthroscopic examination of structures within the plantar pouch of the tarsocrural joint was accomplished via portals in both the plantaromedial and plantarolateral aspects of the joint. Flexion and extension of the tarsus while examining the joint through either portal allowed observation of the proximal and plantar aspects of the lateral and medial trochlear ridges, the trochlear groove, the caudal aspect of the distal tibia, and the deep digital flexor tendon (DDFT) in its sheath. From a plantarolateral portal, the plantar talocalcaneal ligament and the plantar aspect of the lateral malleolus could be observed. The caudal aspect of the medial malleolus could not be observed with flexion or extension of the joint from a plantaromedial portal, but in some horses, the caudal aspect of the lateral malleolus could be observed. The dorsolateral and dorsomedial aspects of the plantar pouch were best examined from a portal on the ipsilateral side of the joint. An instrument portal opposite either arthroscope portal allowed access to most regions of the joint except the abaxial surface of the trochlear ridge opposite the instrument.

摘要:

Enterocutaneous fistulae are rare in horses and occur most commonly as a complication of umbilical hernias or their treatment. Horses with enterocutaneous fistulae may be successfully treated by en bloc resection of the body wall and intestine or by allowing second intention healing. Complications associated with surgical intervention include fever, colic, incisional problems, and recurrence of the fistula. Nonsurgical management of two horses with presumptive large colon fistulae resulted in resolution of the fistulae without complications.

摘要:

Fractures of the distal radius in two horses were repaired by open reduction and interfragmentary compression using screws placed in a lag fashion. One horse had a complete oblique fracture of the medial aspect of the epiphysis of the distal radius and was sound for riding 32 months after surgery. The other horse had an open spiral comminuted fracture with medial displacement of the distal radial fragment. Laminitis developed in the contralateral limb and this horse was euthanatized 5 weeks after surgery. ©Copyright 1994 by The American College of Veterinary Surgeon

摘要:

A double‐blinded, controlled clinical study was performed to compare the response of adult dogs affected with hip dysplasia to a placebo and three different dosages of polysulfated glycosaminoglycan (PSGAG): 2.2 mg/kg, 4.4 mg/kg, and 8.8 mg/kg. Dogs were randomly assigned to treatment groups. The drug was administered intramuscularly every 3 to 5 days for a total of eight injections. Response to treatment was analyzed based on changes in lameness, range of motion (ROM), and pain on manipulation of the hip joints. Evaluation for adverse reactions included complete blood cell (CBC) count, blood urea nitrogen (BUN), creatinine, and physical examination. Data were collected on a total of 111 dogs. Eighty‐four met all criteria for inclusion in the study. Dogs that were given 4.4 mg/kg of PSGAG showed the greatest improvement in orthopedic scores, whereas dogs in the placebo group showed the smallest improvement; however, the differences in clinical improvement between the four treatment groups were not statistically significant. No local or systemic adverse reactions related to the drug were obser

摘要:

In an attempt to reduce postoperative incontinence associated with excisional prostatectomy and the recurrence of prostatic disease after less radical surgeries, a new technique for subtotal prostatectomy was developed using an ultrasonic surgical aspirator. During laparotomy, a longitudinal incision was made in the ventral surface of each lobe of the prostate gland. Biopsies for histology and culture were taken. Through the ventral incisions, the ultrasonic surgical aspirator

摘要:

In an attempt to reduce postoperative incontinence associated with excisional prostatectomy and the recurrence of prostatic disease after less radical surgeries, a new technique for subtotal prostatectomy was developed using an ultrasonic surgical aspirator. During laparotomy, a longitudinal incision was made in the ventral surface of each lobe of the prostate gland. Biopsies for histology and culture were taken. Through the ventral incisions, the ultrasonic surgical aspirator was used to resect approximately 85% of the glandular tissue from inside the capsule. The ultrasonic surgical aspirator allowed resection of the glandular tissue without damaging the vessels, nerves, and connective tissue stroma. The ventral portion of the capsule was excised. The dorsal portions of the capsule were apposed on the ventral midline by suturing their ventral margins to form a periurethral cuff. As preclinical research, seven intact male dogs were evaluated by physical examination, complete blood cell count, serum urea nitrogen, urinalyses, and urethral pressure profile (UPP) with urethral electromyograms (EMGs). The dogs underwent subtotal prostatectomy and castration. All dogs were continent after surgery. UPPs and EMGs at 1 and 2 months after surgery were no different than before surgery. This contrasts to our previous studies in which excisional prostatectomy reduced maximal urethral closure pressure (MUCP) in dogs without prostatic disease. The use of the ultrasonic surgical aspirator for intracapsular subtotal prostatectomy facilitated removal of glandular tissue with decreased hemorrhage and provided preservation of the prostatic urethra, nerves, and vessels involved in maintaining urinary continence.

摘要:

Twenty‐one mandibular fractures in 11 cats and 6 dogs were repaired during a 20‐month period. A new technique using dental composite was used to stabilize the mandible. The canine teeth were pumiced, acid etched, and aligned with dental composite, leaving the mouth opened approximately 1 cm. Six weeks after surgery the composite was removed so that radiographs of the mandible could be made with the animal under general anesthesia. In 1 dog in which the fracture had not healed, the composite was replaced. The composite broke before 6 weeks in 8 animals; 2 required replacement of the dental composite. There were no other complications. The median time for fracture healing was 6 weeks. All fractures healed with anatomic dental occlusion. The advantages of this technique are that no further damage is caused to the teeth or to the blood supply of the bone, the occlusion is anatomic, dermatitis (which is seen with tape muzzles) is not a complication, and the technique is easy to use in brachycephalic breeds, cats, and animals with poor bone quality. The limiting factor of this technique is that it does require four salvageable canine teeth. This repair technique is still a viable option even if one or more of the canine teeth are fractured. Dental composite stabilization is fast, easy, inexpensive, and, in our series, it was 100% effective for the repair of mandibular fractu

摘要:

Six dogs were diagnosed with phcochromocyloma and staged according to the World Health Organization's system for tumor classification. Two dogs had benign tumors (Tl, NO, M0) and four dogs had malignant tumors (T2, NO. M 1 or T3, N0, M0). All dogs had adrenalectomy, two dogs had concurrent nephrectomy, and three dogs had concurrent resection of a tumor thrombus from the vena cava. Anesthetic complications occurred in five dogs, including wide variations in heart rate (four dogs), blood pressure (five dogs), and cardiac arrythmias (one dog). One dog died 12 hours after surgery from partial dehiscence of the suture line and hemorrhage from the vena cava, and one dog died 6 days after surgery during general anesthesia for treatment of laryngeal paralysis. Four dogs survived from 3 to 23 months (median, 15 months). One dog remained hypertensive after surgery. Benign and malignant pheochromocytomas seem to be amenable to surgical resection. ©Copyright 1994 by The American College of Veterinary Surgeon

摘要:

We report the successful use of a cortico‐cancellous bone graft to repair a cleft of the secondary palate in a 6‐month‐old Akita dog. The cleft extended from the incisal papilla to the posterior border of the soft palate. It was 10 mm wide in the hard palate and 16 mm in the soft palate. The cleft was repaired using the “push‐back” method with single‐pedicled mucoperiosteal flaps to close the cleft in the soft tissues, and a free bone graft from the tibia (cortex with cancellous bone attached) to fill the defect in the hard palate. Two and one‐half years after the operation the graft was indistinguishable from surrounding bone on radiographs. Maxillary growth appeared to have progressed normally, resulting in n
