Plain-English summary
A 4-year-old male thoroughbred horse was found to have a serious condition called a dissecting aortic aneurysm, which is a tear in the wall of the aorta, the main blood vessel. Two weeks before the horse died suddenly, it had shown signs of inflammation in its right thigh and had a fever. During the examination after death, doctors found that the aneurysms extended about 40 centimeters along the aorta, and there was a tear in the inner layer of the aorta that led to bleeding around the heart, causing it to stop functioning. Unfortunately, this condition resulted in the horse's sudden death.
Abstract
A case of dissecting aortic aneurysm in a 4-year-old male thoroughbred horse is reported. The horse had a history of inflammation in the right thigh and a fever 2 weeks before sudden death. At necropsy, aortic aneurysms were observed from the aortic valve to the aortic arch, spreading over a distance of 40 cm. An irregular rupture of the intima of the ascending aorta was located in the cardiac side of a ramification to the tunica branchiocephalicus communis. An intramural haematoma, apparent on the cut surface and in the pericardium, had caused cardiac tamponade and sudden death.
