伴内脏脱垂的 Ⅳ 级阴道脱垂，母绵羊

This ewe was previously diagnosed with a grade II vaginal prolapse. Despite placement of a retention suture, the ewe continued to strain, resulting in rupture of the vaginal wall and subsequent evisceration. The resulting trauma elevated the prolapse grade from II to IV. Treatment in this case was humane euthanasia.
