Plain-English summary
In this study, three newborn foals were found to have a rare condition where the left lung didn't develop properly, a problem known as pulmonary agenesis. Each foal also had a hernia, which is when an organ pushes through an opening in the muscle or tissue that normally holds it in place, and their right lung was underdeveloped as well. Unfortunately, all three foals died right after birth due to a lack of oxygen caused by these serious birth defects. This is the first time such a condition has been reported in horses.
Abstract
Pulmonary malformations are rare equine congenital anomalies. Over a 3-year timeframe, three cases of left sided pulmonary agenesis were diagnosed in perinatal foals. All three cases were associated with concurrent ipsilateral diaphragmatic herniation and hypoplasia of the right lung lobe. All three foals died immediately following parturition due to perinatal asphyxia associated with the congenital malformations. To the author's knowledge, this is the first report of pulmonary agenesis in the horse.
