摘要:

Prostatectomy in dogs with clinical prostatic disease has been associated with a high incidence of urinary incontinence. In this study, urodynamic alterations after prostatectomy in 10 dogs without clinical prostatic disease were evaluated. Measurements of residual urine volume, simultaneous urethral pressure profilometry and electromyography, and carbon dioxide cystometry were made before and 14 and 20 weeks after prostatectomy. Voiding was observed daily for 20 weeks after prostatectomy. All dogs remained continent for 20 weeks after prostatectomy, and only minor urodynamic abnormalities were noted. Castration had no effect on urodynamic changes associated with prostatectomy. Prostatectomy produced minimal functional changes in dogs without clinical prostatic disease.

摘要:

Percutaneous nephrostomies (PN) were created with teflon fascial dilators under fluoroscopic guidance, to implant stones bilaterally into the renal pelves of five dogs weighing 7 to 35 kg. Between one and seven stones of 0.25 to 1.00 cm diameter were implanted into each renal pelvis. Two to 4 weeks later, PN tracts were recreated, and the implanted renal stones were successfully removed under fluoroscopic and endoscopic visualization. Results of gross and histopathologic evaluation of the kidneys 2,7,14, 30, and 90 days after stone removal showed minimal, localized renal parenchymal trauma. Complications, although infrequent, included proximal ureteral tears and hemorrhage. Difficulty was encountered in maneuvering equipment around large or numerous stones. Canine percutaneous nephrolithotomy was successful despite great variation in kidney size, as well as variations in the number, size, and shape of stones in the upper urinary tract.

摘要:

Two hundred seventeen cortical bones were harvested cleanly and prepared for banking for 2 months by using one of three types of packing materials, two ethylene oxide (EO) concentrations and procedures, and two storage temperatures. Bone subjected to the various treatments was compared to freshly harvested cortical bone and bone tested immediately after sterilization. Parameters evaluated were handling characteristics during preparation for and placement of a 3.5 mm cortex screw, and the percentage of weight lost as water when the bones were dried in an oven at 100°C for 72 hours. Methods of sterilization, packaging material, and temperature of storage affected the handling characteristics and dehydration of the bone specimens. Twelve per cent EO at an elevated temperature and pressure, paper packaging, and room temperature storage appeared to cause the most significant changes. The use of 84% EO at room temperature and pressure, polyethylene wrapping material, and storage at‐20°C appeared to protect bone from dehydration. There was an increase in cracking and splitting of the bones as the percent of water loss decreased (indicating dehydration at the time of testing). Dehydration due to sterilization and storage processes may lead to difficulty in preparing bone for insertion of a bone screw and subsequently jeopardizing the stability of a repair in which such alloimplants are u

摘要:

Femoral head and neck excision was performed in 169 dogs over a 7 year period. A written questionnaire completed by 56 owners, evaluating a total of 72 joints, was the basis for retrospective evaluation of the efficacy of the procedures used. There were four surgical groups: femoral head and neck excision (FHNE) in dogs with body weights over 14 kg, the same procedure in dogs with body weights less than 14 kg (SMALL), femoral head and neck excision with muscle interposition (Ml), and the wedge resection technique (WRT). Although differences in results were noted, there were no statistically significant differences between any of the groups for the percentage of leg use during normal activity (p>0.05), mean postoperative time until leg use, use of the leg or hopping while running, or lameness with exercise (p>0.10). The results of this study suggest that there is little advantage in performing the more time‐consuming and traumatic muscle interposition and wedge resection procedure

摘要:

Experimentally induced osteofascial compartment syndrome (OFCS) has been reported in the craniolateral compartment of the canine crus. In this study, anatomic dissections and contrast radiographs were used to describe three additional osteofascial compartments in canine limbs. Experimental OFCS was produced in four different compartments, and caused muscle and nerve pathology in each. When compartment pressures were evaluated in traumatized animals, moderate elevations in compartment pressures were found. A compartment syndrome that developed in one dog was surgically decompressed, returning elevated pressures to a safe level.

摘要:

Unilateral distal femoral epiphysiodesis in seven 10 week old crossbred Doberman Pinscher littermates resulted in a significant (p ≤ 0.0001) femoral length deficit of 23.5% without clinically detectable alterations in gait up to 42 weeks after surgery. In addition to compensatory hyperextension of the stifle joint, the ipsilateral tibia showed significant (p ≤ 0.0001) acceleration in longitudinal growth. The combined femoral‐tibial length at necropsy was still significantly shorter (p ≤ 0.0001) in the treated leg than in the control leg despite the increased tibial growth. Unlike other species, neither of the other two femoral growth plates produced any significant compensatory increase in length after fusion of the distal growth plate. The femoral condyles of the treated legs rotated caudally and degenerative joint disease developed in all stifle joints of the treated legs. No contralateral limb abnormalities were evident radiograp

摘要:

Swelling and inflammation along the incision line were observed after elective ovariohysterectomy in 22 of 66 cats in a retrospective study. In a prospective study of 99 feline abdominal incisions closed with surgical gut, polyglactin 910, or polydioxanone, with and without subcutaneous closure, the least inflammation occurred when the linea alba was sutured with polyglactin 910 and the subcutaneous tissues were not sutured. Histologically, reactions in the linea alba of 12 other cats progressed from purulent to fibromono‐nuclear to fibrous within 14 days after closure with gut, polyglactin 910, and polydioxanone. Microscopic evidence of seroma formation in 9 of 12 animals in which the subcutaneous tissue was not sutured suggested that surgical closure of subcutaneous dead space was indicated. The inflammatory reaction did not appear to be related to any one suture material as reactions were seen with all of the

摘要:

Skin defects on the distal extremities of six dogs were reconstructed with free vascular cutaneous transfers by microvascular anastomosis. The donor flaps were based on the superficial cervical artery and vein. In five of the dogs, bone was exposed and skin was lost from half of the circumference of the limb. Two had infected fractures with sequestra and three had acute shearing injuries. The sixth dog had sensory denervation of the left antebrachium and a carpal acral lick granuloma. Before surgery, the patency of potential recipient vessels was confirmed with arteriography in five dogs and an ultrasonic doppler in one dog. Microvascular technique was used to reestablish circulation to the flaps after they were transferred to the recipient site. Total ischemic time of the flaps averaged 100 minutes. All flaps survived. Successful reconstruction of the cutaneous defects was achieved in these six cases.

摘要:

Several surgical alternatives have been described for the management of cecal impaction in the horse, but none has met with consistently successful results. This study was done to evaluate a surgical bypass of the cecum by anastomosis of the ileum to the right ventral colon (ileocolostomy). A ventral midline celiotomy was performed on nine adult ponies (155–350 kg) and a mechanically stapled 10 cm side‐to‐side ileocolostomy was created. In five ponies a complete cecal bypass (CCB) was created by transecting the ileum distal to the anastomosis. In the other four, an incomplete cecal bypass (ICB) was created with no interruption of the ileum. Six horses with clinical cecal impaction also underwent cecal bypass procedures. Five had a CCB and one had an ICB. All the ponies maintained body weight, had no change in consistency of the feces and had no abdominal pain during the 6 month observation period. At necropsy, the lengths of the lateral cecal band, lateral free band of the colon, and the diameter of the anastomotic stoma were compared to measurements made at surgery. The lateral cecal band length decreased significantly more in the CCB ponies than in the ICB ponies (p = 0.008). The anastomotic stoma diameter was significantly larger in the ICB group than in the CCB group (p = 0.032). Five of the six clinical cases recovered and returned to their previous activity. CCB by an ileocolostomy resulted in removal of the cecum from the functional flow of ingesta without complication in the ponies, and was successful in five clinical cases of cecal impa
