Herniation of the abdominal wall in pregnant mares.

The research focuses on the detection and complications of abdominal wall hernia in four pregnant horses. The findings highlight the challenges in diagnosing the specific abdominal wall lesions while emphasizing the severe abdominal pain caused by the hernia in the horses.

Background and Objective

• The primary objective of this study was to analyze the occurrence and complications related to abdominal wall hernias in pregnant mares (female horses).
• The emphasis was placed on investigating the difficulties in diagnosing the specific abdominal wall lesions antemortem (before death).

Observations and Findings

• The study subjects were four mares that were detected with abdominal wall hernias during pregnancy.
• The mares exhibited signs of ventral deviation of the abdomen, abdominal wall edema (swelling), and pain, all of which are usually indicative of a rupture of the prepubic tendon (a tendon located at the lower part of the abdomen).
• However, upon detailed investigation (necropsy, or post-mortem examination), it was revealed that three out of the four mares did not have a ruptured prepubic tendon as initially suspected but were suffering from herniation of the abdominal wall.

Significance and Impact

• The findings highlighted the intricacies and challenges involved in the accurate diagnosis of abdominal wall lesions in pregnant mares.
• The notable feature was the severe abdominal pain, which got further aggravated by incarceration or entrapment of a viscus (an organ within the abdominal cavity).
• The study, thus, underscores the profound impact of abdominal wall hernia on the health and well-being of pregnant mares and calls for more in-depth research in this field.
