Compound presentation is an obstetric condition where an extremity, such as a hand or foot, presents alongside the main presenting part of the fetus, typically the head or breech, during labor. This condition can complicate the delivery process and requires careful management to ensure the safety of both the mother and the fetus.

Pathophysiology

In a normal vertex presentation, the fetal head is the first part to engage and descend through the maternal pelvis. However, in compound presentation, an extremity such as a hand or foot accompanies the head or breech. This can occur due to several factors, including malposition of the fetus, polyhydramnios, or premature rupture of membranes. The presence of an extremity can interfere with the normal mechanics of labor, potentially leading to dystocia or prolonged labor.

Etiology

Compound presentation is often associated with conditions that allow increased fetal mobility or malpositioning. These include:

• Premature rupture of membranes
• Polyhydramnios
• Multiple gestation
• Preterm labor
• Abnormal fetal lie or presentation

Clinical Presentation

The diagnosis of compound presentation is typically made during labor. Clinically, it may be suspected if there is an abnormal progression of labor or if an extremity is palpated alongside the presenting part during a vaginal examination.

Diagnosis

Diagnosis is confirmed through:

• Physical examination: Palpation of an extremity alongside the presenting part.
• Ultrasound: Visualization of the fetal position and confirmation of the presence of an extremity alongside the presenting part.

Management

The management of compound presentation depends on the specific circumstances and the progression of labor. Options include:

• Expectant management: In some cases, the extremity may retract spontaneously, allowing for normal labor progression.
• Manual repositioning: Attempting to gently reposition the extremity away from the presenting part.
• Cesarean section: Indicated if there is fetal distress, failure to progress, or if manual repositioning is unsuccessful.

Prognosis

With appropriate management, the prognosis for both the mother and fetus is generally good. However, careful monitoring is essential to prevent complications such as fetal distress or birth trauma.

Complications

Potential complications of compound presentation include:

• Prolonged labor
• Fetal distress
• Increased risk of cesarean delivery
• Birth trauma
