Does sonographic assessment of fetal head flexion in occiput posterior fetuses at start of second stage of labor predict persistent occiput posterior position?: prospective study.

Our data shows that within a population of women with fetal OP position at the beginning of the second stage of labor the sonographic fetal attitude measured by means of the CCA might help in the identification of fetuses at risk of persistent OP position. Such findings can be useful for patient counselling when OP position is diagnosed at full cervical dilatation. Further studies should investigate if the CCA might select patients who may benefit from manual rotation of the fetal head. This article is protected by copyright. All rights reserved.
