caput succedaneum
Pronunciation: KAP-ut suk-se-DAY-nee-um
Swelling of the fetal scalp that crosses suture lines, caused by pressure during vaginal delivery.
Full Definition
Caput succedaneum is a benign condition characterized by swelling of the soft tissues of the fetal scalp that occurs during labor and delivery. Unlike cephalohematoma, this swelling crosses suture lines and is caused by pressure from the cervix and vaginal walls during passage through the birth canal. The swelling is typically present at birth and resolves spontaneously within 24-48 hours without treatment. It represents edema of the scalp tissues rather than bleeding and is more common after prolonged labor or vacuum-assisted deliveries. The condition is generally harmless but should be distinguished from more serious conditions like cephalohematoma.
Usage
Usage note: Latin term; distinguish from cephalohematoma which does not cross suture lines.
