Compound presentation occurs when the part of the fetus closest to the birth canal (usually the head) presents with an extremity next to it (usually hand or arm) (1). This condition is extremely rare; it’s estimated to affect less than 0.004% of pregnancies.
What causes compound presentation?
Compound presentation can occur as a result of (1):
- The fetal limb becoming trapped below the fetal head
- The fetus not fully occupying the pelvis for some reason, possibly because it is:
- Small for gestational age
- The pelvis is large for fetal size
- The patient presents with polyhydramnios
- The fetus is premature
- There are multiple babies
- Membranes that ruptured while the fetus is still high (premature rupture of membranes), which can allow amniotic fluid to push a limb down before the head
- In the case of multiples, a head of one baby exiting alongside of the other baby’s limb
Diagnosing compound presentation
It’s possible to discover compound presentation on an ultrasound examination before delivery. Right before or during delivery, it may be diagnosed when an irregular form is found next to or in advance of the head or breech during a pelvic exam.
The doctor can confirm compound presentation with either physical examination or ultrasound examination. It is possible for a transverse lie or breech presentation to be misdiagnosed as a compound presentation involving the foot and head. This may require an ultrasound or digital examination to confirm.
Treating compound presentation
Because compound presentation is such a rare finding and its management depends a great deal on patient-specific circumstances, there isn’t much data available to guide general management of the condition.
It is possible that the baby could reposition as labor continues. Commonly, the extremity will retract during labor.
But it is also likely that compound presentation will result in dystocia and arrested labor. If compound presentation does not resolve with gentle pressure or on its own, baby should be promptly delivered via C-section (1).
Birth complications associated with compound presentation
- Arrested labor
- Dystocia
- Cord prolapse
- Injury to the presenting extremity
