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.
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.
Signs and tests
Physical examination confirms that the swelling is a caput succedaneum. No testing is necessary.
Treatment
No treatment is necessary, and it usually heals spontaneously within a few days.
Expectations (prognosis)
Complete recovery can be expected, with the scalp regaining its normal contour.
Complications
Jaundice can result as the bruise breaks down into bilirubin .
Calling your health care provider
This condition is usually noticed immediately after delivery of the child, so no call is necessary -- unless you have additional questions.
Prevention
A caput succedaneum is considered a normal side effect of delivery. No active preventive measures are recommended.
