Thoracic radiographs from 22 neonatal foals were reviewed to investigate the radiographic appearance of the thorax in normal, immature, and septicemic foals, and in foals with neonatal respiratory distress syndrome. The size and radiographic appearance of intrathoracic structures and abnormal lung opacities were evaluated. The craniocaudal and apicobasilar dimensions of the heart were 5.6–6.3 and 6.7–7.8 times the length of a midthoracic vetebral body, respectively, in normal, immature and septicemic foals. Apicobasilar measurements were greater (8.0–8.7) in the foals with respiratory distress syndrome. Normal foals had clear lung fields within 12 hours of birth. A more marked interstitial pattern was observed in immature and septicemic foals compared to normals. Diffuse air–space (alveolar) pattern with air bronchograms was seen in foals with respiratory distress syndrome. It was concluded from this series that thoracic radiographs taken 24–48 hours after birth may aid differentiation of normal foals, septicemic or immature foals, and foals with respiratory distress syndrome. 相似文献

Objective— To describe laparoscopic removal of a large testicular teratoma in a standing horse.
Study Design— Clinical report.
Animals— Thoroughbred horse (11 months) with a testicular teratoma.
Methods— A unilateral cryptorchid testicle could not be removed by an inguinal approach under general anesthesia because of it s large size. After recovery from general anesthesia, ultrasound evaluation revealed a 24 × 19 cm fluid-filled testicular mass. The mass was removed by paralumbar fossa laparoscopy with the horse in a standing position. After fluid aspiration of the mass, the mesorchium and ductus deferens were ligated with extracorporeal knots and the mass retrieved inside a laparoscopic specimen pouch. Morphologic features were consistent with a teratoma.
Results— Laparoscopic-guided aspiration of fluid from the teratoma decreased mass size and increased ease of manipulation and retrieval. Retrieval of the teratoma in a laparoscopic specimen pouch prevented loss of abdominal insufflation, helped reduce fluid leakage, and potential seeding of neoplastic cells.
Conclusion— Use of laparoscopy for removal of neoplastic cryptorchid testicles offers many advantages including minimal invasiveness and increased safety associated with good visibility of structures.
Clinical Relevance— Standing laparoscopic surgery should be considered for removal of testicular neoplasms in horses. 相似文献

Objective— To report a surgical technique for creation of a urethral conduit using a preputial indirect flap.
Study Design— Case report.
Animals— Male Doberman Pinscher (6 weeks old).
Methods— A urethral conduit was constructed using a multistage preputial indirect flap in a dog with severe perineal hypospadias.
Results— Successful transfer of a perineal located urethral meatus to a more anatomically normal inguinal location was achieved with a preputial flap. The procedure was performed to aid control of recurrent urinary tract infections after anal and urethral separation in a dog with imperforate anus, urethrorectal fistula, and proximal perineal hypospadias.
Conclusions— Creation of a urethral conduit from a tubed bipedicle flap using redundant preputial tissue eliminated fecal contamination of the urethral meatus, aiding control of urinary tract infection. A good functional and cosmetic outcome was achieved.
Clinical Relevance— This technique should be considered in aiding control and prevention of urinary tract infections in dogs with proximal perineal hypospadias where a preputial remnant exists. 相似文献

Objective – To determine the association of blood lactate with outcome and response to transfusion therapy in dogs with idiopathic immune‐mediated hemolytic anemia (IMHA). Design – Retrospective study. Setting – Urban veterinary small animal emergency hospital. Animals – One hundred and seventy‐three client‐owned dogs with IMHA. Interventions – None. Measurements and Main Results – Serial blood lactate concentration, therapeutic interventions, and outcome were recorded. Nonsurvivors were defined as those that died or were euthanized. One hundred and thirty‐three dogs (77%) survived, 35 (20%) were euthanized, and 5 (3%) died. One hundred forty‐five dogs (84%; 145/173) had a lactate concentration above the laboratory reference interval [0.46–2.31 mmol/L] on presentation. Blood lactate at presentation was higher in the nonsurvivors (median 4.8 mmol/L; 0.5–13.6) compared with survivors (median 2.9 mmol/L; 0.3–13.2) (P<0.01). All dogs presenting with hyperlactatemia that normalized (<2.0 mmol/L) within 6 hours of admission survived, whereas, 71% of dogs that had a persistent hyperlactatemia at 6 hours survived (P=0.034). Lactate was positively correlated with age, BUN, and alkaline phosphatase, and inversely correlated with PCV. Receiver operating curve analysis for lactate concentration at admission as a test for outcome had an area under the curve of 0.69 with an optimal lactate cutoff concentration of 4.4 mmol/L correctly predicting outcome 73% of the time (sensitivity 60%, specificity 77%). Conclusions – Lactate concentration at presentation was significantly higher in nonsurvivors than survivors. Lactate was significantly correlated with previously reported outcome variables but lactate concentration at admission, as a predictor for outcome was less than optimal. However, serial lactate concentration measurements may be more predictive as patients with persistent hyperlactatemia 6 hours after admission were less likely to survive. Prospective studies evaluating serial lactate concentration while controlling for other variables may provide further insight into lactate measurement as a prognostic indicator in animals with IMHA. 相似文献
