Background

Breech presentation occurs when the fetus presents to the birth canal with buttocks or feet first. This presentation creates a mechanical problem in delivery of the fetus.

Pathophysiology

The buttocks and feet of the fetus do not provide an effective wedge to block and dilate the cervix. The umbilical cord may prolapse, and/or the head may get trapped during delivery.

The 3 types of breech presentation are as follows:

  • Frank (65%): Hips of the fetus are flexed, and knees are extended.
  • Complete (10%): The hips and knees of the fetus are flexed.
  • Incomplete (25%): The feet or knees of the fetus are the lowermost presenting part.
    • Single footling: One of the lower extremities is lowermost.
    • Double footling: Both of the lower extremities are lowermost.

Epidemiology

Frequency

United States

Incidence is correlated to gestational age (see Table 1 below). However, the overall frequency is 3-4% at delivery.[1]

Mortality/Morbidity

  • Many complications can result from breech presentation. They are generally related to complications of the fetal abnormalities that may be the primary reason for the breech presentation and those related to umbilical cord compression resultant from abnormal progression through the maternal pelvis.
  • Increased birth trauma: As the duration of umbilical cord compression increases, the practitioner tries to deliver the infant more rapidly than advisable, thus increasing the incidence of birth trauma.
  • Incidence of prolapsed umbilical cord depends on type of breech presentation.
    • Footling, 17% incidence
    • Complete, 5% incidence
    • Frank, 0.5% incidence
  • Umbilical cord abnormalities: Cord length may be reduced, and, in footlings, there is an increased risk of the cord coiling around the legs of the fetus.

Footling breech presentation. Once the feet have delivered, one may be tempted to pull on the feet. However, a singleton gestation should not be pulled by the feet because this action may precipitate head entrapment in an incompletely dilated cervix or may precipitate nuchal arms. As long as the fetal heart rate is stable and no physical evidence of a prolapsed cord is evident, management may be expectant while awaiting full cervical dilation.
Assisted vaginal breech delivery. Thick meconium passage is common as the breech is squeezed through the birth canal. This is usually not associated with meconium aspiration because the meconium passes out of the vagina and does not mix with the amniotic fluid.
Assisted vaginal breech delivery. The Ritgen maneuver is applied to take pressure off the perineum during vaginal delivery. Episiotomies are often performed for assisted vaginal breech deliveries, even in multiparous women, to prevent soft tissue dystocia.
Assisted vaginal breech delivery. No downward or outward traction is applied to the fetus until the umbilicus has been reached.
Assisted vaginal breech delivery. With a towel wrapped around the fetal hips, gentle downward and outward traction is applied in conjunction with maternal expulsive efforts until the scapula is reached. An assistant should be applying gentle fundal pressure to keep the fetal head flexed.
Assisted vaginal breech delivery. After the scapula is reached, the fetus should be rotated 90° in order to deliver the anterior arm.
Assisted vaginal breech delivery. The anterior arm is followed to the elbow, and the arm is swept out of the vagina.
Assisted vaginal breech delivery. The fetus is rotated 180°, and the contralateral arm is delivered in a similar manner as the first. The infant is then rotated 90° to the backup position in preparation for delivery of the head.
Assisted vaginal breech delivery. The fetal head is maintained in a flexed position by using the Mauriceau maneuver, which is performed by placing the index and middle fingers over the maxillary prominence on either side of the nose. The fetal body is supported in a neutral position, with care to not overextend the neck.
Piper forceps application. Piper forceps are specialized forceps used only for the after-coming head of a breech presentation. They are used to keep the fetal head flexed during extraction of the head. An assistant is needed to hold the infant while the operator gets on one knee to apply the forceps from below.
Assisted vaginal breech delivery. Low 1-minute Apgar scores are not uncommon after a vaginal breech delivery. A pediatrician should be present for the delivery in the event that neonatal resuscitation is needed.
