摘要:

Popliteal tendon transposition was performed in five dogs with surgically induced cranial cruciate ligament rupture. After a lateral approach to the stifle joint, the popliteal tendon was severed distal to the sesamoid bone and transposed cranially onto the tibial crest to mimic the sagittal orientation of the cranial cruciate ligament. The origin of the popliteal tendon on the lateral femoral condyle was preserved. Lameness was not clinically detectable 2 months after surgery. At 6 months postoperatively, there was minimal radiographic and histopathologic evidence of degenerative joint disease in the stifle joints that had underwent surgery. There was no gross or microscopic evidence of meniscal damage found at necropsy 6 months after surgery. Biome‐chanical studies are warranted before recommending the procedur

摘要:

To document and compare patterns of distribution of topically applied antifungal medication, heads from 42 canine cadavers were assigned to seven treatment groups which included two current surgical treatment protocols for nasal aspergillosis, and a new, noninvasive method. Catheters (8 Fr) were placed through trephine holes into the frontal sinuses and nasal cavity. Dilute dye was injected through the catheters and the heads were sectioned sagittally. The administration of 5 mL of dye into the lateral frontal sinus and nasal cavity (group IA, 10 mL total) was compared with 25 mL injected through catheters placed bilaterally in the lateral frontal sinus and nasal cavity (group II, 100 mL total). Both were compared with the administration of 50 mL of dye through a catheter placed in the dorsal nasal meatus via each nostril (group III). The heads in group III had significantly (P<.05) better dye distribution to all cavities than group IA and better distribution to the rostral frontal sinus than group II. Groups IV to VI were designed to show the pattern of distribution of dye to the contralateral nasal cavity and frontal sinuses. In all groups, dye injected into the lateral frontal sinus did not cross into the ipsilateral rostral frontal sinus or vice versa unless the transverse septum dividing the compartments had been penetrated during trephination.

摘要:

This study determined the effect of the polypeptide growth factors transforming growth factor‐beta (TGF‐β), insulin‐like growth factor‐I (IGF‐I), and growth hormone (GH) alone and in combination with dietary L‐Arginine HCL (ARG) on skin flap survival in rats. Caudally based dorsal skin flaps were created in 110 Sprague‐Dawley rats. The rats were randomly assigned into three treatment groups, based on drinking water supplementation. Group 1 (n = 50) received ARG in their drinking water, group 2 (n = 50) received tap water alone, and group 3 (n = 10) received N‐omega‐nitro‐L‐arginine (L‐NA) and hydralazine. Groups 1 and 2 were divided into subgroups of 10 rats each based on treatment with either: TGF‐β, IGF‐I, GH, or IGF‐I + GH. All subgroups that received GH had significantly greater (P<.0001) median body weight gains when compared with subgroups not receiving GH. L‐arginine HCL when added to IGF‐I negated the positive effects of IGF‐I on both flap survival and weight gain. Although the rats in all subgroups from groups 1 and 2 had an increase in mean percent skin flap survival when compared with the water alone subgroup, only rats receiving IGF‐I, or the combination of ARG with either TGF‐β or GH, had statistically significant enhanced skin flap survival. Rats in group 3 did not show an increase in skin flap surviv

摘要:

Eleven mares and four mules were ovariectomized by a ventral abdominal laparoscopic technique. This approach required tilting the operative table about 30 degrees elevating the pelvis to allow observation of the ovaries. A triangulation technique with a single laparoscopic portal and four instrument portals was used. The ovarian pedicles were ligated and the ovaries were removed through a single enlarged instrument portal. Females ranged in age from 5 months to 18 years. Mean operative time was 44 minutes (range 20 to 90 minutes); mean operative time of the last seven animals was 26 minutes. Signs of abdominal pain occurred in three mules and one mare in the immediate postoperative period. Peritoneal fluid collected from six animals 48 hours after surgery had a mean leukocyte count of 34,463/μL: (range, 21,000 to 62,800/μL), mean protein concentration of 3.1 g/dL (range, 2.2 to 4.6 g/dL), and mean differential leukocyte count of 74% neutrophils and 26% mononuclear cells. The animals were confined for 2 weeks after surgery. Signs of estrus were observed in two mares within 6 months after ovariectomy. All owners reported satisfaction with the results of laparoscopic ovariectomy. The ventral abdominal laparoscopic approach permitted efficient and safe ovariectomy of foals and adult

摘要:

Tube cystostomy was used to treat 13 goats and two sheep with obstructive urolithiasis. The cystostomy tube was intermittently occluded 3 to 4 days after placement to determine if urine could be voided through the urethra. If the animal showed no discomfort during urination after the cystostomy tube had been occluded for several days, the tube was removed. This procedure was successful in relieving urethral obstruction in 12 animals. The mean time until the animal could urinate freely and until the cystostomy tube was removed was 11.5 and 14.4 days respectively. Follow‐up was available for 10 animals; seven were alive with no recurrence of urinary obstruction. One goat died from causes unrelated to urinary obstruction 1 year postoperatively. One goat died from unknown causes, and one goat died after urinary obstruction recurre

摘要:

Complications of celiotomy incisions were evaluated retrospectively in 274 horses that survived at least 1 month after surgery, or died or were euthanatized within 1 month of surgery, as a direct result of these complications. Horses were divided into four groups; group A, a ventral median celiotomy for intestinal disease; group B, ventral median celiotomy for nonintestinal disease; group C, repair of an umbilical hernia; and group D, celiotomy in a region other than the midline. Specific incisional complications were peri‐incisional edema, drainage, incisional abscess, suture sinus, and dehiscence. Incision‐related complications occurred in 30% of the horses (group A, 40%; group B 18%; group C, 7%; and group D, 88%). Complications occurred more frequently in group D than group A (P=.009), which were higher than in groups B and C (P<.00001). Incisional hernia occurred in 28 of 256 (11%) horses that survived at least 4 months and were available for follow‐up. Hernia formation was more common (P<.00001) in horses that had other incisional complications (23 horses) than those without (5 horses). Serous or purulent incisional drainage, were more likely to be associated with hernia formation than was serosanguineous drainage or other incisional complica

摘要:

Jejunojejunal intussusception occurred after jejunal resection and stapled functional end‐to‐end anastomosis in two pony mares. In both mares, the lead point of the intussusception was the stapled functional end‐to‐end (FEE) anastomosis. The stapled free ends of jejunum were oversewn with an inverting suture pattern. A possible explanation for development of the intussusception was the acute angle created in the intestine by the FEE anastomsis. This angulation may have impaired flow of ingesta causing motility changes that predisposed the site to intussusception. Because the oversewn blind intestinal ends acted as the lead point for formation of the intussusception, it may be inadvisable to oversew the stapled anastomot

摘要:

We prospectively studied 18 dogs that presented for exploratory stifle arthrotomy, with or without meniscectomy, and lateral extracapsular stabilization as a result of cranial cruciate ligament rupture. Dogs were premedicated with acepromazine, induced with thiopental, and maintained with halothane in oxygen. Preoperatively, dogs were assigned to one of three groups. Group 1 (n = 6) received intra‐articular morphine (0.1 mg/kg diluted in 1 mL/10 kg body weight of saline) and epidural saline (1 mL/5 kg body weight saline plus the volume of saline representing 0.1 mg/kg of morphine). Group 2 (n = 6) received intra‐articular saline (1 mL/10 kg body weight of saline plus the volume of saline representing 0.1 mg/kg of morphine) and epidural saline (1 mL/5 kg body weight saline plus the volume of saline representing 0.1 mg/kg of morphine). Group 3 (n = 6) received intra‐articular saline (1 mL/10 kg body weight of saline plus the volume of saline representing 0.1 mg/kg of morphine) and epidural morphine (0.1 mg/kg of morphine diluted in 1 mL/5 kg body weight saline). The efficacy of each analgesia regimen was evaluated for 6 hours postoperatively with a pain score based on subjective and objective variables. Serum Cortisol and blood glucose concentrations were measured. Butorphanol was used to provide analgesia as needed based on a predetermined maximum pain score. Supplemental analgesics were required postoperatively every 2 to 3 hours for 6 hours in all dogs that did not initially receive analgesics (group 2). Pain scores were significantly lower in dogs administered morphine intra‐articularly (group 1) and epidurally (group 3) at 30 minutes and 30, 120, and 360 minutes, respectively, compared with dogs that did not initially receive analgesics (group 2). One dog in group 1 and one dog in group 3 required supplemental analgesia with butorphanol. There was no difference between analgesia produced by intra‐articular morphine compared with that of epidural morphine. Side effects after intra‐articular or epidural morphine were not observed. Intra‐articular administration of morphine can produce effective analgesia in dogs comparable with that produced by epidural administratio
