Fetal head entrapment within the lower uterine segment

Abstract Fetal head entrapment by a uterine scar or adhesion is a rare obstetric complication. We present a case of a uterine constriction diagnosed in pregnancy that resulted in confinement of the fetal head to the lower uterine segment. The developing fetus ultimately suffered growth restriction of the head and was delivered after the mother experienced preterm premature rupture of membranes (PROM). Severe adhesions of the lower uterine segment were confirmed during the patient’s classical cesarean section.
