Caput succedaneum

• Overview
• Symptoms
• Treatment
• Prevention

Definition:

Caput succedaneum is a diffuse swelling of the scalp in a newborn caused by pressure from the uterus or vaginal wall during a head-first (vertex) delivery.

Alternative Names:

Caput

Causes, incidence, and risk factors:

A caput succedaneum is caused by the mechanical trauma of the initial portion of scalp pushing through a narrowed cervix . The swelling may be on any portion of the scalp, may cross the midline (as opposed to a cephalhematoma), and may be discolored because of slight bleeding in the area. There may also be molding of the head, which is common in association with a caput succedaneum.
