Plain-English summary
A 24-year-old Thoroughbred gelding had trouble breathing for a few days and experienced some nosebleeds before sadly passing away. During the examination after death, veterinarians found that certain blood vessels in the horse's lungs were twisted and enlarged. They discovered that there was an unusual connection between two types of blood vessels in the lungs, which is called a bronchopulmonary artery fistula. This case is notable because it appears to be the first documented instance of this condition in a horse. Unfortunately, the treatment options were not applicable since the horse had already died.
Abstract
A 24-year-old, Thoroughbred gelding presented with difficulty breathing for a few days and intermittent nose bleeding before dying. At necropsy, the bronchoesophageal artery and the bronchial artery that flowed into the left anterior lobe were tortuous and dilated, and it was found that dilated tortuous branches of the bronchial artery ran over the dorsal and ventral surfaces of the left anterior lobe. Histopathologically, an anastomosis between a muscular artery and an elastic artery were demonstrated, which were identified as bronchial and pulmonary arteries, respectively. Based on the gross and histopathological findings, a bronchopulmonary artery fistula was diagnosed. To the best of our knowledge, this is the first case report of a pulmonary vascular anastomosis in a horse.
