Caudal vena cava thrombosis-like syndrome in a horse.

Abstract: A 9-year-old Quarter horse was presented for chronic refractory pneumonia. On necropsy, an hepatic abscess, caudal vena cava thrombosis, pulmonary thromboembolism, and embolic pneumonia were identified. Similar lesions have been reported in cattle as caudal vena cava thrombosis syndrome, however this syndrome has not previously been reported in horses. Un cheval Quarter horse âgé de 9 ans est présenté pour une pneumonie réfractaire chronique. À la nécropsie, un abcès hépatique, une thrombose de la veine cave caudale, un thromboembolisme pulmonaire et une pneumonie embolique ont été identifiés. Des lésions semblables ont été signalées chez le bétail comme étant le syndrome de la thrombose de la veine cave caudale; cependant, ce syndrome n’avait pas déjà été signalé chez les chevaux.

This research explores a case of a 9-year-old Quarter horse suffering from persistent pneumonia. Upon examination, the horse was discovered to have a unique combination of health issues that were previously identified as caudal vena cava thrombosis syndrome in cattle, but not in horses.

Objective of the Study

  • The underlying objective of the study is to investigate the unusual health complications in a Quarter horse. Specifically, it attempts to identify whether the symptoms and conditions prevalent in the horse are synonymous with caudal vena cava thrombosis syndrome, which is typically identified in cattle but not previously documented in horses.

About the Case

  • The subject of the study is a 9 years-old horse of the Quarter breed. The horse was initially presented in a condition of chronic refractory pneumonia that was not improving over time.
  • Eventually, the horse underwent a necropsy—a post-mortem examination to determine the cause of illness or death. From this process, several health issues were discovered within the horse.

Findings from the Necropsy

  • Firstly, the horse was identified to have an hepatic abscess. An hepatic abscess is a collection of pus within the liver typically resulting from a bacterial infection.
  • Secondly, caudal vena cava thrombosis was found in the horse. Caudal vena cava thrombosis is a condition where a blood clot forms in the caudal vena cava—the large vein that carries deoxygenated blood from the lower half of the body back to the heart.
  • Thirdly, pulmonary thromboembolism was identified. This condition occurs when one or more arteries in the lungs become blocked by a blood clot.
  • Lastly, the condition of embolic pneumonia was found. This form of pneumonia is caused by emboli—objects originating elsewhere in the body and being transported by the blood supply to the lungs—where they can then cause infection.

Significance of the Findings

  • What makes these findings unique is that this combination of conditions resembles a syndrome known as caudal vena cava thrombosis syndrome, which has been reported in cattle, but not in horses before this case.
  • Thus, this research signifies a potentially new understanding of horse health, allowing for better insight and precautionary measures for horse carers and veterinarians.
