Topic:Case Reports
Case reports in equine medicine provide detailed accounts of individual horses' clinical presentations, diagnostic processes, treatments, and outcomes. These reports are valuable for documenting rare conditions, novel treatment approaches, or unique clinical insights that may not be captured in larger studies. By focusing on individual cases, these reports contribute to the broader understanding of equine health and disease management. They often include comprehensive information on the horse's history, clinical findings, diagnostic tests, therapeutic interventions, and follow-up evaluations. This page assembles peer-reviewed case reports and scholarly articles that explore diverse aspects of equine health, offering insights into specific medical scenarios and their implications for veterinary practice.
Dropsy of the fetal sacs in mares: induced and spontaneous abortion. Eight cases of severe dropsy of the fetal sacs have been observed in mares. All were in multiparous mares whose ages ranged from five to 20 years and who were 7 1/2 to 10 3/4 months pregnant. Abortion started spontaneously in four cases and had to be induced in the remaining four by manual dilation of the cervix, rupture of the tough allantochorion and the siphoning off of 120 to 220 litres of allantoic fluid. The amnion was normal. Dystocia, due to uterine inertia, occurred in all eight cases, one hydrocephalic fetus needing fetotomy. All fetuses were alive at delivery although four were tera...
Lamellar corneal transplantation in the horse. Surgical correction of corneal opacities in horses has rarely been documented in detail and is still reported to be in the experimental stage. For this reason, studies of lamellar keratoplasty were conducted on the equine eye using a modified trephine with an adjustable inside quard for grafting of identical discs from the donor and the recipient cornea. Fourteen transplantations, seven with homografts and seven with heterografts, 15 and 9 mm in diameter, were performed. Sharp-edged, vertical, and regular outlined wound margins of the graft and host are essential for good adaptation and healin...
The importance of blood gas measurement in the diagnosis of an intraventricular septal defect in a horse: a case report. An 18 month Thoroughbred gelding was diagnosed on cardiac catheterization as having an interventricular septal defect. Right side cardiac blood pressures were within the normal range and confirmation of the diagnosis came from changes in the blood pO2 and pCO2 between the right atrium and right ventricle. The significance of these values is discussed.
Diaphragmatic hernia in horses. The clinical and necropsy findings of three cases of diaphragmatic hernia admitted to Ontario Veterinary College between September 1973 and August 1974 are described. The physical signs of these and other reported cases are discussed, as are methods of diagnosis. Definitive diagnosis is best arrived at by exploratory laparotomy.
Rostral displacement of the palatopharyngeal arch: a case report. A horse with rostral displacement of the palatopharyngeal arch was found to have a bilaterally symmetrical deformity of the laryngeal area. Both left and right cricopharyngeal muscles were absent. The shape of the thyroid cartilage was grossly abnormal and vestiges of the cricothyroid muscles were attached only to the cricoid cartilage. It was suggested that such an anomaly could have resulted from aberrant development of the fourth branchial arch.
Four cases of Tyzzer’s disease in foals in England. A rodent pathogen, Bacillus piliformis, has been recognised as causing a rapidly fatal hepatitis in 4 foals in England. The disease in foals has been recognised in America since 1973. A clinico-pathological account of the 4 cases is given and the differential diagnosis discussed. The 4 foals' ages fell within a very narrow range (24-34 days). Some of the properties of this unusual intracellular pathogen are reviewed. For the first time in the equine the bacillus was seen in association with myocardial lesions. There are marked differences in the epidemiology of the disease in the mouse and in ...
Urethral sphincterotomy for delivery of vesical calculus in the mare: a case report. A case of vesical calculus in which haematuria was not a presenting sign is described. Methods of removal of vesical calculi are discussed. In this case, urethral sphincterotomy facilitated delivery.
Epidermoid cyst of the brain in the horse. An aged Connemara mare had a neurological illness lasting 3 weeks and characterised by episodes of dullness, head-pressing, staggering gait and hyperexcitability. The signs recurred at intervals of 3 to 4 days, with intervening periods of apparent normality. Post-mortem examination revealed an epidermoid cyst on the dorsal surface of the occipital lobe of the left cerebral hemisphere. The cyst was lined by stratified squamous epithelium and contained desquamated keratinised material and blood. The lesion is considered to be a congenital malformation which enlarges and produces space-occupying ...
Fractures of the pedal bone in the horse. A series of 79 fractures of the pedal bone in various types of horses are reported and the clinical features described. The fractures were of 3 types--intra-articular or extra-articular, involving the wing of the pedal bone, and fractures of the extensor process. Forty-five horses with a fractured wing of the pedal bone were treated conservatively and 11 by immobilisation of the bony fragment with a compression screw. Conservative treatment was usually successful in the extra-articular fractures. Intra-articular fractures treated conservatively in animals under 3 years had a good prognosis. Th...
Villonodular synovitis of the equine metacarpophalangeal joint. Villonodular synovitis was diagnosed as the cause of lameness in 14 horses. The diagnosis was based on the history, clinical signs, and arthrographic findings. Treatment consisted of surgical excision and radiation therapy. The response to treatment was favorable in 13 horses.
Neuropathological changes associated with the neonatal maladjustment syndrome in the thoroughbred foal. A neuropathological investigation was carried out on the brains of 18 foals suffering from the neonatal maladjustment syndrome and results were compared with those obtained from the brains of nine foals dying from other causes. Necrosis of the cerebral cortex of an ischaemic nature was found in nine of the neonatal maladjustment foals, frequently accompanied by local haemorrhage. In three of this group of foals there was also necrosis in the diencephalon and brain stem. In the brains of the nine other affected foals there was haemorrhage in the cerebrum and sometimes in the brain stem and cere...
