摘要:

Extended‐hip ventrodorsal pelvic radiographs performed on 16 dogs after femoral head and neck excision, with (n = S) and without (n = 8) biceps femoris interpositional muscle flaps, were used to estimate the relative amount of soft tissue interposition between the femoral ostectomy site and acetabulum. A linear measurement was made of the shortest distance between the femoral ostectomy and the acetabulum. The linear measurement was capable of determining the presence of biceps femoris muscle flaps in most dogs prior to flap atrophy or necrosis, but failed to be predictive of limb function as determined by functional limb usage grading, force plate analysis, and thigh circumference measurement

摘要:

Twenty‐one dogs with histopathologically confirmed hemangiosarcoma were evaluated by thoracic radiography for metastatic disease. All dogs had histopathologic examinations of the lungs within two weeks of thoracic radiography. Fourteen dogs had histopathologic evidence of pulmonary hemangiosarcoma; metastatic disease was detected radiographically in eleven of these dogs. The most common radiographic pattern was that of poorly defined small coalescing nodules (8 dogs); other radiographic patterns included well‐circumscribed nodules (3 dogs) and alveolar infiltrates secondary to hemorrhage (2 dogs). Differential diagnoses for diffuse, poorly defined, coalescing pulmonary opacities should include hemangiosarcoma in addition to edema, lymphoma, systemic mycoses, fibrosis, allergy, toxicosis, and carcino

摘要:

Compartment syndrome is an elevation of interstitial pressure in a closed osseofascial compartment that results in microvascular compromise. This report documents a clinical syndrome in the crus of a fourteen‐month‐old intact male Labrador Retriever which was consistent with trauma‐induced compartment syndrome. A six month history of recurring trauma or complications resulted in the need for referral. Survey radiography and ultrasonography aided in the diagnosis, but the definitive answer was provided by femoral angiography. The patient was successfully treated and was discharged with normal limb function. One year later, there were no complications observed. Compartment syndrome is not uncommon in humans, and is routinely considered in certain blunt and most penetrating traumas. However, few reports of this complication in animals are

摘要:

Contrast medium opacification of the spinal central canal after cisterna magna or lumbar puncture caudal to the 5th lumbar vertebra was an unusual observation during myelography. Incidental central canal opacification was more likely to occur in normal dogs or dogs with spinal cord pathology during lumbar puncture cranial to the 5th lumbar vertebra. Preferential contrast medium migration into the central canal, particularly if injected rapidly, may lead to deterioration in neurologic status. Placement of the spinal needle in the central canal during cisterna magna myelography was necessary to document the presence of hydromyelia. Case histories illustrating the above conditions were given and their significance discussed.

摘要:

Computed tomography (CT) was performed on 3 normal Rambouillet sheep and 6 Rambouillet sheep affected with neuronal ceroid lipofuscinosis. Characteristic lesions seen in the brain of affected sheep included dramatically enlarged lateral ventricles and reduced cerebral thickness. The lesions were seen in sheep as young as 4 months of age. Antemortem CT observations correlated well with postmortem findings in this model of Neuronal Ceroid Lipofuscinosis.

摘要:

Intraoperative spinal ultrasonography was performed in cervical and lumbar spine of 2 and 5 normal dogs, respectively, following ventral slot technique or dorsal or hemilamenectomy. The dura was hyperechoic, while the parenchyma was hypoechoic. The subarachnoid space was anechoic. An echogenic line was present in the center of the spinal cord, as seen in human. Pulsation of the spinal cord was noted during M‐mode imaging. Clinical findings of one dog with thoracolumbar disk herniation and one with thoracic vertebral fracture/subluxation confirmed the usefulness of intraoperative spinal ultrasonography for real time evaluation of spinal canal spatial abnormalities (mass lesion and degree of spinal cord compression on scanning planes) and spinal cord motion. Follow‐up ultrasound examinations were possible from 6 days postoperativ
