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.
Equine carpal surgery: A review of 89 cases and evaluation of return to function. During a 6-year period, carpal arthrotomies were performed on 89 horses with carpal fractures. Fifty-two percent of the fractures involved the left forelimb; the 3rd carpal bone was most often involved (42%), followed by the radial carpal bone (30%). The effect of surgery on the performance of a subgroup of 48 thoroughbreds was evaluated by comparing the number of starts, level of racing (claiming value), and earnings for the 12 months of racing preceding and following arthrotomy. The data indicated that carpal arthrotomy in the Thoroughbred carries with it a favorable prognosis inasmuch as 80...
Persistent dorsal displacement of the soft palate associated with epiglottic shortening in two horses. Persistent dorsal displacement of the soft palate was diagnosed in 2 Thoroughbred horses examined because of decreased exercise tolerance and a respiratory noise during strenuous exercise. The persistent dorsal displacement of the soft palate was caused by an epiglottis that was approximately 2/3 normal size, and thus was incapable of maintaining the soft palate in a normal subepiglottic position. Contrast pharyngography suggested a primary epiglottic abnormality. Visual assessment of the lesion was accomplished by exploratory ventral laryngotomy and endoscopy of the oropharynx per os. Surgica...
Clinical, morphological and endocrinological aspects of cryptorchidism in the horse. The authors analysed clinical, histological and hormonal data obtained from 205 cryptorchid horses. The majority of the unilaterally and bilaterally retained testes were located in the inguinal canal; however, the ratio of inguinal vs abdominal retention appeared to decrease with advancing age. In unilateral cryptorchidism, a pronounced preference was noted for left abdominal retention, whereas for inguinal cryptorchids, the retained testes occurred equally on both sides. Right inguinal retention was found to decrease with advancing age. Histology of cryptorchid testes revealed apparently norm...
Infection of the central nervous system of horses with equine herpesvirus serotype 1. During the last 2 years different equine herpesviruses serotype 1 strains have been isolated from cases of paretic or paralytic disease among horses in the Federal Republic of Germany. In this paper the available information is collated and briefly reviewed. A short description of the symptoms and the possible mechanism of the pathogenesis are given.
Actinobacillus lignieresii infection after a horse bite. Perforation is the most serious complication of fibreoptic endoscopy.1
The commonest site of perforation during upper gastrointestinal
endoscopy is the oesophagus,' but predisposing factors have not been
fully documented. We report a retrospective survey of major endoscopy
units in the United Kingdom and attempt to identify the factors associated with oesophageal perforation.
Surgical management of uterine torsion in the mare: a review of 26 cases. Uterine torsion was diagnosed in 26 mares of various breeds. The mean duration of gestation was 9.6 months. The most common clinical history was intermittent unresponsive colic of varying duration. Diagnosis of uterine torsion was confirmed by rectal palpation, and surgical correction was achieved in most cases by standing flank laparotomy and manual repositioning of the gravid uterus. Recumbent laparotomy was used only if the mare was intractable, the uterus was ruptured, or hysterotomy was indicated. Of 20 foals determined to be alive during surgery, 14 (70%) were subsequently born alive.
Uterine prolapse in a mare. A prolapsed uterus in a mare and the techniques to successfully replace the organ and prevent complications such as shock, laminitis and metritis are described.
Treatment of equine phycomycosis by immunotherapy and surgery. Treatment of equine phycomycosis with a vaccine derived from ultrasonicated hyphae of Hyphomyces destruens was attempted in 30 cases of clinical hyphomycosis, 10 cases of hyphomycosis following unsuccessful surgery and 5 cases of basidiobolomycosis. Approximately 53% of animals with clinical hyphomycosis were cured after vaccination, while a further 33% clinically improved. All horses with hyphomycosis treated within 2 weeks of unsuccessful surgery were cured. There was no response to vaccination with a Hyphomyces preparation in horses with basidiobolomyucosis, while surgery alone resulted in ...
Anatomy and therapeutic resection of the peroneus tertius muscle in a foal. A foal with a congenital flexure deformity of the right hock was unable to walk because of an abnormally short peroneus tertius (PT) muscle. Tension on the muscle origin and insertions limited the dorsal angle of hock extension to a 70-degrees arc. The intrauterine position of the fetus probably caused the defect. All the PT attachments were dissected in several other limbs, and illustrations made from these dissections were used to study the anatomy and surgical approach. Immediately after resection of the PT muscle, the foal's right hock extended an additional 30 degrees. Two months later, t...
Acute hemolytic anemia, methemoglobinemia, and heinz body formation associated with ingestion of red maple leaves by horses. From June 1975 through June 1979, acute hemolytic anemia developed in 11 horses from 7 New York farms. Of the 7 horses that died, 6 had methemoglobinemia. In the 4 horses that recovered, methemoglobinemia was not observed. but Heinz body formation was seen in 3 of the 4. On 2 of the premises involved, frank methemoglobinemia was observed concurrently with Heinz body formation, suggesting a relationship between the pathogenesis of methemoglobinemia and Heinz body formation in the hemolytic process. In addition to the 11 cases described, 22 clinically similar cases were reported to us during the...
Congenital duodenal stenotic diaphragm in the foal. A two-month-old female foal with duodenal stenosis is described. The foal was in poor condition and showed an abnormal stable behaviour. She stood preferably with her head stretched out and reposing on the mare's back or on the stable ridge. Salivation was an important symptom. Clinical and radiological examination of the oral cavity, the pharynx, and the oesophagus showed no abnormalities, except for the antiperistaltic wave along the oesophagus. Because of her bad condition the filly was euthanized. At post mortem examination, apart from leukoplakia, an erosive ulcerative inflammation was fo...

Laryngeal paralysis in Arabian foals associated with oral haloxon administration. Bilateral laryngeal paralysis is described in 5 Arabian and part-Arabian foals aged between 23 and 35 days. Tracheotomies resulted in complete relief of dyspnoea. Two cases showed recovery of abductor function of the right arytenoid cartilage after 3 weeks and one of these cases later recovered left abductor function. Four of the foals were autopsied at various times from one week to 6 months after the onset of respiratory obstruction. Histology of the recurrent laryngeal nerves showed active Wallerian degeneration and loss of nerve fibres in many fascicles in cases affected for one to 2 weeks...
