Objective —To evaluate hinged circular external fixation for correction of antebrachial deformities in dogs.
Study Design —Uncontrolled clinical trial.
Animal Population —Seven client-owned dogs.
Methods —Six dogs had one radius corrected and one dog had both radii corrected. Preoperative planning included measurement of the craniocaudal and mediolateral angular deformities, rotational deformity, length deficit, origin of deformity, graphical or mathematical determination of the amplitude and direction of the actual limb deformity, and frame assembly.
Results —Preoperatively, function and cosmesis were assessed to be fair to poor in all dogs. Deformity correction started 48 to 60 hours postoperatively and ranged from 0.46 mm to 1.36 mm twice daily. Hospitalization time ranged from 4 to 6 days. Corrections were mostly made by the owners, at home. Lengthening and angular correction ranged from 3 to 38 mm and 18° to 48°. Mean residual deformities were 2.7% of radial length and 2.7°. The time duration with the circular external fixators in place ranged from 29 to 71 days. Two additional surgeries were necessary in one dog because of wire breakage. Mean follow-up was 40 months. Long-term function and cosmesis were good to excellent in all dogs.
Conclusion—Although complications were present in six of seven dogs, the outcome of hinged Ilizarov external fixation was successful in all dogs treated for deformities of the antebrachium.
Clinical Relevance —Despite complex preoperative planning, the placement of hinged circular external fixators is straightforward, and allows precise correction of complex antebrachial deformities with minimal tissue trauma. 相似文献

Hydrothorax was identified in a 14-year-old Siamese cat with a pre-existent perinephric pseudocyst. The pleural fluid was classified as a low-protein transudate. Intrapseudocystic scintigraphy confirmed a direct communication between the pseudocyst and the pleural space. The hydrothorax resolved following pseudocystectomy and unilateral nephrectomy, demonstrating that the psendocyst caused the hydrothorax. 相似文献

Objective— To describe anatomic considerations and arthroscopic technique in horses for arthroscopic removal of palmar/plantar osteochondral fragments from the proximal interphalangeal (PIP) joint. Study Design— Retrospective study. Animals— Adult horses (n=4) with osteochondral fragments of the palmar/plantar PIP joint. Methods— Arthroscopic removal of palmar/plantar osteochondral fragments within the PIP joint was performed with horses in dorsal recumbency under general anesthesia. Medical records of affected horses were reviewed to determine history; physical, lameness, and radiological findings; surgical technique; complications and outcome. Results— Two horses had lameness localized to the PIP joint. Two other horses had lameness suspected, but not confirmed to the pastern region. One of these horses had a history of intermittent lameness, but was not lame on admission. All horses had radiographic evidence of palmar/plantar osteochondral fragmentation within the PIP joint. Fragmentation was located abaxially in 2 horses in the hind limb and axially in 2 horses in the left forelimb. Osteochondral fragments were successfully removed via a palmar/plantar arthroscopic approach in all horses. Three horses returned to previous levels of athletic performance; 1 horse was used for trail riding instead of reining. Conclusions— Arthroscopy of the palmar/plantar pouch of the PIP joint allowed limited assessment of the joint and removal of osteochondral fragments. Clinical Relevance— Arthroscopy of the palmar/plantar PIP joint pouch for assessment and removal of osteochondral fragments is possible and should be considered when lameness is localized to this joint. 相似文献

A retrospective study of 15 dogs and three cats was done to characterize the appearance of meningeal enhancement on magnetic resonance (MR) images of the brain, and to correlate this appearance with its underlying cause. Two patterns of meningeal enhancement (pial and dural) were identified. Enhancement of the pia mater was evident in four dogs and one cat, while enhancement of the dura mater was seen in 11 dogs and 2 cats. A variety of causes of meningeal enhancement were identified, including bacterial and cryptococcal meningitis, plasmacytic meningitis with associated subdural fluid accumulation, granulomatous meningoencephalomyelitis, inflammation secondary to otitis interna, feline infectious peritonitis, and neoplasia. The present study confirms that pial or dural meningeal enhancement may be present on MR images of the brain of dogs or cats in association with a variety of central nervous system diseases. A larger prospective study is required to further establish the incidence of specific patterns of meningeal enhancement seen in association with specific diseases. 相似文献

Splenectomy was performed in 15 crossbred dogs; hilar vessel ligation was used in eight dogs (group 1) and splenic and short gastric artery ligation were used in seven (group 2). Blood flow to six sites along the greater and lesser curvatures of the stomach was recorded with radioactive tracer microspheres. A significantly higher blood flow was recorded in group 2 for the site supplied by the right gastroepiploic artery (p = 0.0441). There was no difference between the groups for the site supplied by the left gastroepiploic and short gastric arteries. Histologically, there was no difference in gastric tissue samples from four sites. Splenic and short gastric artery ligation did not compromise stomach blood flow or the integrity of the stomach wall, and may be superior for splenectomy because of its relative simplicity and potentially shorter operative time. 相似文献

Intra-abdominal pressure (IAP) was indirectly measured, using a transurethral catheterization technique, in 20 client-owned dogs before and after elective ovariohysterectomy. Mean preoperative IAP was 4.50 ± 0.44 cm H2 O. Elective abdominal surgery caused significant elevations in mean postoperative IAP (mean 7.50 ± 0.45 cm H2 O, range 0 to 15 cm H2 O) that persisted for at least 24 hours. However, the increase in IAP caused no clinically evident complications; thus, after elective abdominal surgery an elevation in IAP up to 15 cm H2 O is to be expected. Intra-abdominal pressure was also measured in 20 consecutive clinical cases with gross abdominal distension, before or after laparotomy, or both. Included in this group were dogs with gastric dilation and volvulus, closed pyometra, hemoperitoneum, acute ascites, and diaphragmatic hernias. All dogs with gross abdominal distension had an elevated IAP (> 16 cm H2 O) either before or after surgery. Severe elevations of IAP were associated with anuria in two dogs, necessitating surgical decompression; one with hemoperitoneum (47 cm H2 O) and one after repair of a chronic diaphragmatic hernia (30 cm H2 O). 相似文献

The effects of intravenously administered atropine (0.2 mg/kg) and glycopyrrolate (0.01 mg/kg) on heart rate were studied in 10 conscious mature goats. In a drug cross-over fashion, either atropine, glycopyrrolate, or 0.9% saline solution was administered using the same volume (0.05 mL/kg). Atropine and glycopyrrolate caused a significant increase in heart rate ( P <.05), whereas saline solution (0.09%) did not. The mean percent changes in heart rate from baseline were similar for atropine and glycopyrrolate up to 14 minutes after administration. Thereafter, glycopyrrolate had a significantly greater mean change in heart rate than atropine, ie, up to 29 minutes ( P <.05). Within the atropine group, the mean percentage changes in heart rate became significantly lower compared with the initial increase (1 minute) starting at 11 minutes. For the glycopyrrolate group, the mean percent changes became significantly lower starting at 27 minutes. Glycopyrrolate and atropine had a mean percentage change in heart rate of greater than 1.0%, up to 31 and 22 minutes, respectively. At the doses used, glycopyrrolate had longer duration of action than atropine but the magnitude of increase was similar. 相似文献

Nasal cavity radiographs and CT images from 31 dogs with nasal cavity cancer were compared. All dogs had abnormal clinical signs relating to -nasal cancer and histologic confirmation of malignant nasal cavity neoplasia. No dog had cyto reductive surgery prior to imaging. All radiographic and CT examinations were abnormal. CT was more accurate than radiographs in identifying unilateral versus bilateral nasal cavity disease and tumor extension into adjacent structures such as the cranial cavity, hard palate, and pterygopala-tine fossa. The improved accuracy of CT in these respects was not of benefit in the confirmation of nasal cavity disease because radiographs were abnormal in every instance. However, CT may be useful for more accurate tumor staging, predicting possible treatment-related complications, and planning of surgery and radiation therapy. It was also determined that one dorsally located radiation therapy portal bounded laterally by the medial ocular canthi, as described in previous reports, would not have been adequate for encompassing all abnormal tissue in 28 of the 31 dogs evaluated. 相似文献

Subtotal dorsal cervical laminectomy was used to relieve spinal cord compression due to cervical vertebral malformation in 16 horses. The majority were Thoroughbred or Quarter Horse males, 1 to 4 years old. The caudal cervical vertebrae were involved in all but two instances. A Funkquist type B laminectomy was performed and the defect filled with a free autogenous nuchal fat graft. All horses recovered from surgery without complication or deterioration in neurological status. Neurological improvement occurred in 12 cases, including six that became sound. Three horses fractured a vertebral articular process and were euthanized. A modification to the shape of the laminectomy was adopted to reduce this complication. 相似文献
