摘要:

Radiographs of the navicular bone in 523 sound horses were reviewed. Detailed evaluation criteria were used. The incidence of radiographic changes and variations in normal horses were recorded. Results were tested for right‐left limb difference and for age relationship. Variation in shape and bone structure was commonly seen in the navicular bone. Radiographic changes with an incidence of less than 2% included flexor cortex defects and calcification on the flexor surface. Fragments at the distal navicular bone border, calcification in the impar ligament and enthesiophytes at the proximal border were radiographic findings with an incidence of 2% to 10%. Abnormal canals at the distal border were found in 11% horses. Elongation of the lateral proximal extremity was commonly found. The mean width of the flexor cortex was 3.6 m

摘要:

Radiographic examination of all four metatarso‐ and metacarpophalangeal joints was performed on 753 Standardbred yearlings. Ununited proximoplantar tuberosity of the proximal phalanx was seen in 18 (2.4%) of the horses. All ununited tuberosities were in the pelvic limb. The condition was seen laterally in 16 horses while one horse had the medial and lateral tuberosities affected and another only the medial tuberosity. Upon follow‐up examination it was apparent that 12 ununited proximoplantar tuberosities in 11 horses had united to the proximal phalanx after 6–12 months. A worsening of the condition was seen in 4 horses, and one horse had unchanged radiographic findings after 7 months. Lameness had not been observed in any horse prior to the first examin

摘要:

Acute pelvic limb paralysis occurred in a racing Greyhound after a traumatic incident. During myelography, a dorsal laceration of the dura mater was detected at T12–13. Immediate hemilaminectomy was performed at T12–13, but neurologic status did not improve. At necropsy there was epidural and subdural hemorrhage at the T12–13interspace, and malacia and swelling of the spinal cord at that level. Intramedullary hemorrhage, malacia, and free fibrocartilaginous material characterized histopathology of the lesion. Possible mechanisms of the traumatic disk extrusion are disc

摘要:

This paper describes coarctation of the aorta with a large fusiform post‐stenotic aneurysm in a 6 year old Great Dane. No clinical signs were attributable to the lesion, which was an incidental finding. The radiological and pathological features of aortic coarctation are describe

摘要:

A vulvovaginal discharge following parturition in a bitch is often a cause of concern to owners and clinicians, especially if whelping was complicated in any way. Ultrasonography could potentially distinguish between normal and abnormal postpartum uterine states because the uterine wall and luminal contents can be imaged in detail. Five normal bitches were examined to determine the normal ultrasonographic appearance of the postpartum uterus and the sensitivity of ultrasonography in detecting the involuting uterus, comparing this sensitivity with that of radiography. Ultrasonography was done at 1, 4, 8, 12, 18 and 24 days postpartum, radiography at 1, 4, 8, 12 and 18 days postpartum. By 12 days postpartum, the uterus could not be seen on radiographs, while at 24 days postpartum the uterus was still sonographically identifiable. The ultrasonographic characteristics of the involuting uterus are described.

摘要:

A 7‐week‐old Appaloosa filly was admitted for persistent urinary incontinence since birth. Vaginal speculum examination revealed urine flowing from an opening in the right vaginal wall. Cystoscopy demonstrated that the ureters did not terminate at the bladder. The endoscope passed easily from the vagina directly into a dilated right ureter. An excretory urogram confirmed the vaginal termination of at least one ureter, based upon extensive filling of the vagina with contrast media in the absence of bladder filling. Bilateral hydroureter and dilated renal pelves were demonstrated both by excretory urography and by ultrasonography. Euthanasia was requested by the owner in lieu of attempted surgical correction. At necropsy, it was confirmed that the right ureter entered the vagina and the left ureter terminated at the urethra. The diagnosis of bilateral ectopic ureter in this foal was suggested by the history and clinical signs, supported by endoscopy and ultrasonography, and confirmed by excretory urography and necropsy. This case establishes the value of diagnostic imaging techniques in the antemortem diagnosis of ectopic ure
