Segmental ischemic necrosis of the small intestine in two postparturient mares.

The research discusses two cases of female horses (mares) which encountered a condition of reduced blood flow leading to the death of tissue, or necrosis, in certain segments of their small intestines after giving birth.

Research Background and Case Presentation

• The cases involve two mares which developed a serious intestinal condition known as segmental ischemic necrosis after parturition, or childbirth. This condition is considered critical as it refers to the death of tissues in the intestines due to inadequate blood supply.
• The study draws attention to postparturition issues in mares that can potentially affect their overall health and productivity as broodmares.

Findings and Animal Response

• In the first case, a part of the small intestine’s supportive tissue called ‘mesentery’ is believed to have torn during parturition. Following this, necrosis developed in a 52-cm long segment of the ‘jejunum’, a midsection of the small intestine.
• In the second mare, the upper portion of the ileum, another part of the small intestine, tore during childbirth resulting in necrosis in a similarly long section of the intestine.
• Three weeks after the event, a 40-cm section of the lower part of the small intestine again got stuck within the tear in the mesentery, leading to a full circle or 360-degree twist on its mesenteric base. This condition is known as volvulus, a life-threatening condition if not treated promptly.

Intervention and Outcome

• The critical condition of the affected mares was addressed sensibly by performing a ‘resection’. This surgical procedure involves removing part or all of the affected intestine to prevent further complications.
• The successful treatment led to their recovery, and both mares returned to function as broodmares, which indicates that they were capable of breeding again.

This research emphasizes the importance of being alert to health issues in postparturient mares, and it underscores the effectiveness of surgical interventions in the management of serious complications.
