Plain-English summary
A mature mare developed a serious condition called an intramural hematoma, which is a collection of blood inside the wall of her intestine, affecting a 40-centimeter section of her jejunum (a part of the small intestine). This caused her to have colic, which is severe abdominal pain, and led to an intestinal blockage. The affected part of her intestine was surgically removed, and she had a successful recovery. However, four years later, she experienced colic again due to a different issue involving twisting of the intestine and scar tissue from previous surgeries. While the exact cause of the initial hematoma wasn't clear, it was thought that it might have been related to a parasite that can affect horses. Overall, the mare recovered completely from the first surgery.
Abstract
An intramural hematoma involving a 40-cm segment of the distal portion of the jejunum caused intestinal obstruction and colic in a mature mare. The involved intestine was resected, and an end-to-end anastomosis was performed. The mare recovered completely, but 4 years later had colic caused by incarceration and volvulus of the distal portion of the jejunum, involving fibrous abdominal adhesions. The cause of hematoma was not identified; however, rupture of an intramural vessel after migration of Strongylus vulgaris larvae was considered a possibility because of the histologic observation of an intense eosinophilic infiltrate in the region. Vascular rupture caused by blunt abdominal trauma was considered unlikely. Previous descriptions of intramural hematoma in the horse have been confined to the small colon.
