Vagina: trauma

pequis

Introduction

  • Vagina is less commonly traumatized than the cervix Cervix: trauma or vulva at foaling but can be damaged at breeding.
  • Cause: include trauma to the vaginal wall by the foal's foot and obstetric damage; failure to perform episiotomy (reversal) of Caslick's Vulva: Caslick operation prior to foaling; natural breeding accidents.
  • Signs: range from unnoticed injuries with fresh blood on the dismounting stallion's penis to acute peritonitis. Rarely, bowel will prolapse through the damaged vagina. Rectovaginal fistulae Perineum: trauma and perineal tears can form if the hoof penetrates the rectum as well as the vagina.
  • Treatment: varies depending on position, degree and cause of the laceration but can include:
  • Surgical repair in the standing animal.
  • Sedated animal under epidural anesthesia Anesthesia: epidural after infusing antibiotics into the peritoneum through the deficit in the vaginal wall.

Pathogenesis

Etiology

  • Dystocia Reproduction: dystocia - foal's foot perforation/ripping of vaginal wall anywhere from cervix caudally.
  • Obstetric intervention, eg assisted foaling Reproduction: foaling management, embryotomy.
  • Breeding injuries (natural) due to over-forceful penetration of vagina by stallion's penis: this most commonly damages the cranial vagina. Can be associated with a large penis compared to the size of mare.

Pathophysiology

  • Subsequent to foaling or copulation.
