Topic:Necropsy
Necropsy, also known as an autopsy, is a systematic examination of a horse's body after death to determine the cause of death and evaluate any disease or injury. This procedure involves a thorough assessment of the horse's organs and tissues, often including histopathological analysis to identify abnormalities at the microscopic level. Necropsy can provide valuable insights into equine health issues, contributing to a better understanding of disease processes, management practices, and potential preventive measures. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, findings, and implications of necropsy in equine veterinary science.
Haemangioendothelioma in domestic animals. The study comprises 49 dogs, 2 horses, and 2 cows with haemangioendothelioma, which have been subjected to autopsy over a period of 26 years. Most of the dogs were old, and there is an over-representation of male dogs. The results also indicate that the Alsation breed of dog is particularly susceptible to these tumours, as is the Boxer to some extent. The disease was in most cases of short duration and the most common clinical symptoms were sluggishness, fever, generalized anaemia, breathing difficulties, increased thirst, and leuco-cytosis. Most of the dogs fell ill and were subjected to auto...
Microscopic lesions in the hearts of aged horses and mules. The hearts of 23 aged equids (18 horses and 5 mules) were examined histologically. Major findings included arteriolosclerosis and intimal bodies in small muscular arteries, myocarditis, myocardial fibrosis, fatty metamorphosis of myocardial and Purkinje fibers, myocytolysis, and basophilic (mucinous) degeneration of myocardium. Lesions less frequently seen included chronic fibrotic valvulitis, acute myocardial necrosis, sarcosporidiosis, and hemosiderosis. Single cases of malignant melanoma, cartilaginous metaplasia of the I-V septum, mineralization of connective tissue in the I-V septum, and ...
Functional and morphologic pathology of equine aortic insufficiency. Twelve horses and 3 mules with grade II or louder prolonged diastolic murmurs were selected for functional and histopathologic study. Aortic insufficiency was demonstrated in all mules and in all except two horses on the basis of murmurs, jet lesions and/or pathologic and incompetent valve cusps. In 15 control animals lesions resulting in aortic insufficiency were not found.
A thick fibrous band was present on all aortic valve cusps judged to be definitely insufficient. This band occurred at the line of valvular closure, parallel to the free edge, and allowed eversion of the peripheral portio...
[A gastrointestinal stromal tumour of the caecum in a pony with colic]. A 25-year-old pony mare was presented to the clinic with preliminarily reported severe acute colic. The pony during the previous week had shown inappetence, apathy and fever of unknown origin. Clinical examination and placement of a gastric tube were indicative of a secondary gastric dilation. Rectal exploration found moderate caecal meteorism with a tensed and painful medial taenia as well as a dilated and fluid-filled small intestine. In addition, a solid, mobile, non-painful structure of approximately 10 cm diameter was palpated ventrally. A hyperechogenic mass close to the caecum was detec...
Prevalence of large endoparasites at necropsy in horses infected with Population B small strongyles in a herd established in Kentucky in 1966. Two closed horse herds (Old Lot 4 and Field 24), infected since 1966 with Population B small strongyles resistant to thiabendazole (TBZ) and phenothiazine (PTZ), were terminated in February, March, and May, 2005. At necropsy, only the large endoparasites were identified and counted. The number of horses on pasture was 14 (239 days of age to 23 years old) for Old Lot 4 and two (3 to 20 years old) for Field 24. The time of the last antiparasitic treatment, relative to the year (2005) of necropsy, was 26 years for Old Lot 4 and 9 years for Field 24 horses. Gasterophilus intestinalis third instars...
A retrospective study of the prevalence in equine postmortems of cranial mesenteric arteritis caused by Strongylus vulgaris in Alberta (2010 to 2022). is one of the most pathogenic nematodes affecting equids. Larval migration through the cranial mesenteric artery (CMA) with attendant arteritis and thromboembolism can result in fatal non-strangulating intestinal infarction. Once considered a historical disease, recent studies have described the reemergence of this pathogen in several European countries; however, little is known of the current prevalence of in the Canadian horse population. Unassigned: To determine the prevalence of active cranial mesenteric arteritis in horses submitted for postmortem examination to the Diagnostic Services...
