Introduction

  • This article describes the technique used to perform a cesarean section and discusses the decision making processes involved in determining when a cesarean section is appropriate.  
  • Please be aware that this information is designed to be a useful guide for the veterinary surgeon, but is not prescriptive.  The decision making process will very much depend on the individual case and its unique circumstances. 

Uses

Maternal dystocia
  • Expulsive defect:
    • Myometrial defect:
      • Primary uterine inertia (inability of the uterus to contract sufficiently).
      • Secondary uterine inertia (decreased effectiveness of uterine contractions as parturition progresses).
    • Defective or inadeqate straining.
  • Inadequate birth canal:
    • Failure of cervix, soft tissues or ligaments to relax.
    • Uterine torsion; definitely if  complete torsion (>2700).
    • Obstruction of birth canal, eg pelvic fracture.
  • Inadequate pelvic diameter*
Fetal dystocia
  • Fetal oversize:
    • Normal but large*.
    • Defective or monster calf.
  • Faulty disposition or alignment:
    • Abnormal presentation.
    • Abnormal position.
    • Abnormal posture.
  • Fetal death.
  • Signs of fetal distress.
*these two factors combined or separately can be described as fetomaternal disproportion.

Elective cesarean
  • History of previous dystocia or cesarean.
  • Predictable dystocia due to breed predisposition, eg Belgian blue cattle Belgian blue cattle or misalliance, eg heifer too small when mated.

Advantages of performing the procedure

  • Increased chance of a live calf if intervention is performed early.
  • Reduced chance of secondary complications to cow, eg peripheral neuropathies.

Disadvantages

  • Cost.
  • Risk of surgical and post-surgical complications in the dam, including death.
  • May reduce subsequent fertility of dam.
  • Anesthetic depression of calf (if sedative used).
