摘要:

Anastomotic leakage was noted to occur at the junction of the staple lines used to create the stoma during small intestine side‐to‐side anastomosis. The anastomosis was performed in a clinical equine patient by joining the lateral surfaces of the intestinal segments using a gastrointestinal anastomosis stapling instrument (GIA). The cause of this problem was investigated by performing six anastomoses in the jejunum of a single anesthetized adult horse using the GIA; three anastomoses were created by joining the antimesenteric edges of the bowel segments and three anastomoses were created by joining the lateral surfaces of the bowel segments. Bowel segments were then dissected to examine the stoma and the integrity of the staple lines. No defects were detected in anastomoses performed by joining the antimesenteric edges. Anastomoses performed by joining the lateral surfaces all had a defect at the junction of the double rows of staples used to create the stoma. Such defects would have allowed leakage of fluid and/or ingesta at the anastomotic s

摘要:

Priapism occurred in a stallion after the administration of acetylpromazine. When conservative measures failed, the corpus cavernosum penis (CCP) was drained and irrigated, and a vascular shunt between the erectile bodies was created. Subsidence of erection resulted, but subsequently, the stallion was unable to retract or erect the penis. The stallion was castrated and the penis was surgically retracted into the sheath.

摘要:

Positive cultures were obtained from 60 equine orthopedic cases during a 12 year period (1974–1985). These cases consisted of 34 long or cuboidal bone fractures, 13 arthrotomy/arthroscopy procedures for removal or internal fixation of a fracture, 7 proximal splint bone fractures, and 6 facial or mandibular fractures. Excluding the 13 arthrotomies, only 10 (21%) of the 47 were open fractures. Multiple organisms were isolated from 36 cases (20 long or cuboidal bone fractures, 7 splint bone fractures, 5 mandibular fractures, and 4 intra‐articular fractures). Of the 142 isolates, 35 (24%) were members of the family Enterobacteriaceae, 33 (23%)Streptococcusspp., and 25 (18%)Staphylococcusspp. with the majority being coagulase positive (65%). Other organisms isolated werePseudomonasspp. (16, 11%), obligate anaerobes (11, 7%), andActinobacillusspp. (7, 5%). The remaining 10% consisted ofPasteurellaspp.,Bacillusspp.,Corynebacteriumspp.,Micrococcusspp., andActinomycesspp. When comparing results between two time periods (1974–1979 and 1980–1985) there was an increase in the percentage of coagulase positive staphylococci isolates resistant to all antimicrobics tested except oxacillin and amikacin, andEscherichia coliisolates were resistant to all but amikacin. ForPseudomonasspp., resistance to gentamicin increased in the second time period (1980–1986). During the initial time period (1974–1979) culture tests for obligate anerobes were not conducted until 1975. No anerobes were cultured during those initial 5 years; however, one third of those isolated after 1980 were resistant to penicillin and ampicillin. There were no cases of apparent acquired resistance against the antimicrobial agents used during therapy when comparing the susceptibility patterns of the organisms cultured perioperatively to those obtained at impl

摘要:

Fourteen dogs were presented with caudal cruciate ligament (CaCL) rupture without concurrent cranial cruciate ligament (CrCL) rupture. The history usually included moderate to severe trauma. Presenting signs included lameness, positive drawer sign, and additional orthopedic injuries. A final diagnosis of CaCL rupture was made during surgical exploration of the joint in 12 of the dogs. In nine of the dogs, this diagnosis was not included in the preoperative differential diagnoses, and seven of the dogs were misdiagnosed as sustaining CrCL rupture. Methods of treatment included intracapsular and extracapsular stabilization. Follow‐up time ranged from 3 weeks to 7 years. Function of the limbs was good regardless of surgical procedure chosen and did not appear to depend upon stifle stabilit

摘要:

The strength and holding power of four pin designs for use with half pin (type I) external skeletal fixation were evaluated. Pins that were tested were fully threaded, nonthreaded, two cortices partially threaded, and one cortex partially threaded. The study involved three parts: (1) resistance of the pins to axial extraction immediately after insertion; (2) resistance of the pins to axial extraction 8 weeks after being inserted into the tibiae of live dogs; and (3) resistance of the pins to bending load. Pins with threads engaging two cortices were more resistant to axial extraction than nonthreaded pins in both the acute (p<0.0001) and chronic (p<0.0001) studies. Nonthreaded pins were more resistant to bending than fully threaded and two cortices partially threaded pins (p<0.0005). One cortex partially threaded pins possessed similar bending strength to nonthreaded pins (p = 0.21) and had 5.3 times more resistance to axial extraction in the acute study (p<0.0001) and 6.9 times more in the chronic study (p<0.0001). Though one cortex partially threaded pins were not as resistant to axial extraction as pins with threads engaging two cortices (p<0.0001), they were more resistant to bending loads (p<0.0005). Loss of holding power and pin failure are two of the most serious problems associated with fracture stabilization using external skeletal fixation. The results of this study suggest that one cortex partially threaded pins are better at maintaining holding power and resisting bending and breaking than nonthreaded pins. With some compromise in holding power, they are also better at resisting failure than pins with threads engaging two cortices.

摘要:

Persistent nonchylous pleural effusion followed thoracic duct ligation for chylothorax in a dog. Attempts at tetracycline pleurodesis twice failed to reduce the quantity of pleural effusion. Repeated thoracentesis caused malnutrition and hypoproteinemia. A modified Denver® peritoneal‐venous shunt was implanted to internally drain the pleural fluid into the peritoneal cavity. Normal body weight and plasma protein concentration were regained in 40 days. Digital compression of the pump chamber alleviated the signs of respiratory compromise, without complication. At 50 weeks post‐installation, a proteina‐ceous clot obstructed the original efferent pump valve, necessitating shunt replacement. Eight weeks after replacement, the dog was asympt

摘要:

Axial pattern flaps based upon the genicular branch of the saphenous artery and medial saphenous vein were developed in eight dogs. On one hind limb of each dog, the experimental flap was raised and immediately transferred to a cutaneous defect created over the lateral aspect of the lower limb distal to the stifle. A control flap was elevated and transferred on the opposite hind limb with the genicular branches of the saphenous artery and vein ligated and divided at the base of the flap. Eighty‐nine per cent of the length of the flap survived in those flaps in which the genicular vessels were left intact, whereas only 54% of the flap's length survived in the control flaps. Postoperatively, all dogs were bearing weight on the limbs normally. The genicular axial pattern flap may have special clinical application in cases of cutaneous defects involving the lateral aspect of the tibi

摘要:

Sixteen normal 20 to 30 kg dogs had standard femoral head and neck excision (8 dogs) or femoral head and neck excision with interposition of a biceps muscle flap (8 dogs). Lameness lessened at week 6, and did not differ between groups; neither group returned to a completely normal gait. Weightbearing decreased on the operated pelvic limb compared to controls (forceplate analysis). Weightbearing force of the muscle flap dogs was significantly less at weeks 6 and 16 than that of the standard femoral head and neck excision dogs. The operated limb of both groups was shortened; shortening was significantly greater for the muscle flap group. Hip extension was limited in both groups. Both groups had decreased (more acute) hip, stifle, and hock angles measured in standing position. Thigh muscle atrophy was more pronounced in the muscle flap group at week 6. More soft tissue was interposed in the muscle flap group at necropsy compared to the group with standard femoral head and neck excision, but the difference was not statistically significant. Skeletal muscle fibers were present in the interposed fibrous connective tissue of the muscle flap group, and the healed surfaces were smoother than those of the standard femoral head and neck excision group.

摘要:

Although techniques for the perioperative management of patients undergoing mitral valve replacement have been well established in humans, the use of these techniques has not been widely accepted in veterinary practice. The purpose of this study is to demonstrate that low morbidity and mortality could be achieved in the dog undergoing mitral valve replacement. Nine mongrel dogs (25–45 kg body weight) were subject to left thoracotomy and mitral valve replacement using cardiopulmonary bypass (CPB). The average time on CPB was 1 hour with an aortic cross‐clamping time of 40 minutes using chemically induced cardiac arrest. CPB was performed under conditions of moderate systemic hypothermia (28–30° C) and hemodilution (hematocrit, 25–35%). Operative mortality was 22% (2/9) with one death from excessive bleeding and the other from cerebral air embolism. All other animals recovered and were clinically normal 3 weeks after surgery. The authors conclude that successful mitral valve replacement is possible in the l

摘要:

Thirty seven dogs and cats were subjected to lobectomy, partial lobectomy, or pneumo‐nectomy using stapling equipment. The most common indication was neoplasia. No operative, perioperative, or long‐term deaths could be attributed to the use of staples; complications were minimal. Staple resection was believed to be safe, fast, and efficient for removal of various segments of canine and feline l
