Persistent brow presentation: a new approach to management.
When the fetal vertex is extended on the spinal column and the brow becomes the presenting part, it is termed "brow presentation." Persistent brow presentation occurs when there is no spontaneous conversion after the onset of active labor. Since there is a risk in the vaginal delivery of such fetuses, it should not be attempted where there is known maternal disease or evidence of acute or chronic intrauterine fetal distress. During labor, cesarean section is indicated if there is cephalopelvic disproportion, if the fetal head is not in the frontoanterior position, if there is abnormal labor, or if there is evidence of fetal distress. Continuous lumbar epidural anesthesia should be given, and only manual conversion is used. The fetus is monitored continuously.
