In the recent edition of Equine Veterinary Education, the case report of a 24-day-old Friesian colt who died suddenly was published by a group of veterinarians from the Western College of Veterinary Medicine in Saskatoon, Canada. This very young colt had an uneventful delivery and nursed well at birth, had a normal IgG and physical examination findings. He was found dead in the afternoon following a thunderstorm, lying on his left side with no signs of a struggle.
Physical examination of the foal showed no abnormalities and the body of the foal was transported quickly such that a necropsy was performed very shortly after death. Findings included blood in the chest cavity a with a rupture of the aorta at the aortic root. Histopathology also showed the presence of two bacteria in the large colon, but this was considered to be an incidental finding, although of interest due to the type and location of these two bacteria.
Relevance: This case study and the accompanying clinical commentary help to bring to the forefront the issue of aortic rupture in the Friesian horse to any veterinarian reading this journal. Some of the references sited for this case study include articles by some researchers familiar to us all (Drs. Ploeg, Delasalle and Back). Knowledge is power and education of the veterinary community with issues such as this helps all of us do a better job of caring for these wonderful horses.
