“…Tachycardia, tachypnoea, congested mucous membranes, prolonged capillary refill time, and "toxic line" were recorded. Similar signs (except for congested mucous membrane) were reported in the previous case report described in the nonpregnant mare (Steward et al 2018). These clinical signs are common in SISO (Withers and Mair 2008) and a definitive diagnosis can be made after additional diagnostic tests.…”

“…Two cases have been reported in pregnant mares (Becht and McIlwraith 1980;Freeman and Schaeffer 2011). Recently, this pathology was reported in a nonpregnant mare with two past pregnancies without a history of dystocia (Steward et al 2018).…”

“…The degree of severity in SISO depends on the obstruction site, the time and degree of strangulation (Datt and Usenik 1975). Based on the strangulation site, one of the most rarely reported cause is SI herniation through the broad ligament (Steward et al 2018). This pathology can occur in pregnant mares during late gestation, when the foal reaches a size that could influence the uterus position and SI migration into a created defect (Steward et al 2018).…”

“…Two cases were reported in pregnant mares, one of which was described as a SI herniation through the mesometrium at 8 month of gestation (Becht and McIlwraith 1980), whereas the other was only briefly mentioned in a study by Freeman and Schaeffer (2011). The forth case was a SI herniation through the mesometrium in a nonpregnant mare with a history of 2 normal pregnancies (Steward et al 2018). Given the rarity of this lesion, this case report describes in detail the clinical signs and pathological outcomes in a nonpregnant mare with SI herniation through the broad ligament, providing novel insights in diagnosis, possible treatment options and prevention.…”

Small intestinal herniation through the broad ligament in a mare outside of the gestation period – a case report

A Furioso-North Star mare, aged 8 years, was examined for colic signs. The mare had a history of dystocia and post partum vaginal lacerations, acute endometritis and laminitis approximately one year before the admission for colic. Signs of persistent abdominal pain, moderate distended abdomen, non-passage of manure, fever, tachycardia, tachypnoea, congested mucus membranes, and “toxic line” were recorded. No intestinal borborygmi were present in the four quarters of the abdomen. On rectal examination, the colon, the ventral band of the caecum, the right ovary and the uterine horn were palpated on the right side of the abdomen. The spleen, the nephrosplenic ligament, the left ovary and a firm, distended and painful small intestine (SI) loop were palpated on the left side. The left uterine horn and the adjacent broad ligament were not detectable. Percutaneous abdominal ultrasound evaluation revealed a large amount of fluid in the abdominal cavity, SI distention and absence of peristalsis. Abdominocentesis yielded approximately 20 ml of red-tinged peritoneal fluid with increased mean protein concentration (5.2 mg/dl), white blood cell count (12,550 cells/μl), and lactate (14 mmol/dl). A presumptive diagnosis of SI strangulation was made. Surgical resection of the affected intestinal loops was recommended. Due to poor prognosis and financial limitations, the mare was euthanized. Post mortem macroscopic diagnosis was a herniation of 3 metres of the mid-jejunum through the left mesometrium, resulting in a complete and complicated strangulation. To prevent this type of SI strangulation, we recommend transrectal palpation of the urogenital tract (including the broad ligament) after foaling. If a defect is identified, we recommend flank laparoscopy for correction.

SummaryThis report describes segmental ischaemic necrosis of the small intestine 4 days after foaling in a 9‐year‐old Arabian mare. The jejunal mesentery was avulsed from the intestine in two locations for 20 and 200 cm, resulting in intestinal necrosis, in the absence of entrapment or strangulation. This case highlights the need to consider the possibility of mesenteric injury when a post‐partum mare presents mild signs of abdominal pain.

A 13-year-old multiparous Quarter Horse mare was presented to the Michigan State University’s, Large Animal Emergency service for dystocia. Clinical evaluation revealed a minimally dilated cervix on vaginal examination, with a palpable deceased fetus. Postmortem evaluation following owner-elected humane euthanasia revealed a circumferential, tan, fibrous band at the base of the uterine body that constricted the uterus and was adhered to the left and right ovaries. A routine histologic section of the incarcerating cord attached to the ovary consisted predominately of dense fibrous connective tissue, large blood vessels, and a central oviduct suggestive of a rent in the broad ligament. To the authors’ knowledge, this is the first case report to describe uterine body constriction that precluded vaginal delivery of a fetus in a late gestation mare.
