Cervix: trauma - repair

Contributor(s): David Moll

Introduction

  • The cervix is the last physical barrier to the uterus and has a vital role in uterine defense.
  • The cervix is made up of longitudinal muscle along its body and circular muscle at the internal and external os.
  • The shape and function of the cervix is determined by hormonal control.

Uses

  • Trauma to the cervix occurs most commonly at foaling; especially if induced, protracted, assisted or where fetotomy is performed   Cervix: trauma  .
  • Occasionally damage may occur at breeding.
  • Cervical damage may go undetected and result in decreased fertility with conception failure and early fetal loss   Abortion: early embryonic / fetal death  .
  • Cervical tears are typically wedge-shaped with the apex pointing anteriorly.
  • Most tears occur on the dorsal cervical body.
  • Cervical lacerations which are extensive or deep must be repaired surgically.

Disadvantages

  • Visualization may be difficult and requires adequate retraction of the cervix and the use of a light source.
  • Repair of ventral tears is more difficult and may require general anesthesia   Anesthesia: general - overview  and dorsal recumbency for adequate visualization of defect.

Prognosis

  • Good for small, single linear tears which don't tend to recur.
  • Guarded for future breeding in all mares with major cervical damage.
