This study analyzed 156 cases of fetal hydrocephalus treated at Osaka National Hospital from 1992 to 2011 to review current methods for diagnosing and treating fetal hydrocephalus, and for estimating its clinical outcome. This was a retrospective study of a single institute (Osaka National Hospital). Of 156 cases in total, 37% were diagnosed as isolated ventriculomegaly, 50% as another type of malformation (36 cases of myelomeningocele, six of holoprosencephaly, three of DandyeWalker syndrome, one case of Joubert syndrome, 12 of arachnoid cyst, nine of encephalocele, three of atresia of Monro and eight of corpus callosum agenesis, and 13% as secondary hydrocephalus. Diagnoses were made between 13 and 40 weeks of gestation (average 27 weeks). Diagnosis was made before 21 weeks of gestation in 24% of cases, from the first day of 22 weeks to the sixth day of 27 weeks in 27%, and after the first day of 28 weeks in 49%. With the exclusion of 17 aborted cases and 40 cases in which the patients were too young to evaluate or lost during follow-up, the final outcome was analyzed for 90 cases. Of these, 17% of the patients died, 21% showed severe retardation, 13% moderate retardation, 26% mild retardation, and 23% showed a good outcome. The long-term outcome was mostly influenced by the basic disease and accompanying anomaly. The time of diagnosis showed no correlation with outcome. Hydrocephalus associated with arachnoid cyst, atresia of Monro, and corpus callosum agenesis, and hydrocephalus due to fetal intracranial hemorrhage, resulted in good outcomes. By contrast, holoprosencephaly, hydrocephalus associated with encephalocele, syndromic hydrocephalus, and hydrocephalus due to fetal virus infection led to poor outcomes. For accurate diagnosis and proper counseling, established protocols are important for the diagnosis and treatment of fetal hydrocephalus, including not only fetal sonography, fetal magnetic resonance imaging, and TORCH (toxoplasma, rubella, cytomegalovirus, herpes simplex) screening test, but also chromosomal and gene testing.
Fetal therapy for congenital hydrocephalus—where we came from and where we are going
Child's Nervous System
Despite unfavorable outcomes during the early experience with in utero intervention for congenital hydrocephalus, improvements in prenatal diagnosis, patient selection, and fetal surgery techniques have led to a renewed interest in fetal intervention for congenital hydrocephalus. Research studies and clinical evidence shows that postnatal cerebrospinal fluid diversion to release intraventricular pressure and cerebral mantle compression usually arrives late to avoid irreversible brain damage. Make sense to decompress those lateral ventricles as soon as possible during the intrauterine life when hydrocephalus is antenatally detected. We present a historical review of research in animal models as well as clinical experience in the last decades, traveling until the last years when some research fetal therapy groups have made significant progress in recapitulating the prenatal intervention for fetuses with congenital obstructive hydrocephalus.

Congenital hydrocephalus: gestational and neonatal outcomes
Archives of Gynecology and Obstetrics, 2010
Purpose To evaluate gestational and neonatal outcomes in pregnancies complicated by fetal hydrocephalus. Methods Retrospective analysis of 287 cases of fetal hydrocephalus followed at the Fetal Medicine Unit of the University of Campinas in the period of 1996 to 2006. Results Mean maternal age was 25 years, mean gestational age at diagnosis was 27 weeks. There were 50 cases of isolated ventriculomegaly, 95 cases of Chiari II malformation and 142 cases of ventriculomegaly associated with other malformations. Preterm delivery and vaginal delivery were more frequent in the group of ventriculomegaly associated with other malformations. Cardiac, skeletal and renal malformations were the most common associated malformations. Cesarean section was common (95%) in the Chiari II group. Fetal and neonatal death occurred more frequently (29 and 68%, respectively) in the group of ventriculomegaly associated with other malformations. Chromosomal anomalies were present in 15% of 165 investigated cases.

The aim of this study was to draw the attention of specialists faced with fetal hydrocephalus in the postnatal period to the possibilities of prenatal diagnosis and further monitoring by studying isolated and syndrome cases in fetuses. One hundred and nine fetuses from a total of 2238 autopsies were the subject of observation in this study. In 64 (58.7%) of the studied fetuses, isolated hydrocephalus was found, while the other 45 cases were associated with the following malformations: Arnold-Chiari type II, Dandy-Walker, stenosis of the aqueductus sylvii, agenesis of corpus callosum (partial and total) and numerical chromosomal aberrations such as trisomy 13, 15 and 18. In cases of isolated hydrocephalus and a stable condition of the fetus, it is possible to wait until the term, or to induce labor without danger to the child, followed by a shunting intervention.
Intrauterine hydrocephalus and ventriculomegaly: associated anomalies and fetal outcome
Canadian Journal of Neurological Sciences, 1985
Advances in fetal diagnostic techniques have opened many areas to prenatal anatomical scrutiny. Intrauterine hydrocephalus and ventriculomegaly are conditions which are readily diagnosed. Fetal intervention has been undertaken in humans in order to minimize the craniofacial disfigurement and to maximize the growth potential of the brain. To justify such an approach, the significance of all anomalies should be recognized prior to treatment. The authors have reviewed 41 cases of hydrocephalus diagnosed in utero in order to define associated anomalies and patient outcome. 75% of our personal series and 72% of the reviewed literature cases had other anomalies of the central nervous system. Other system malformations, some of which proved fatal, were seen commonly. Prenatal diagnostic techniques did not always reveal these additional problems. The outcome of these pregnancies is not good. Approximately one third of these fetuses have survived to be treated postnatally and to be followed ...

The natural history, medical management, and outcome in infants with progressive posthemorrhagic hydrocephalus after intraventricular hemorrhage were studied prospectively. Infants with asymptomatic severe posthemorrhagic hydrocephalus were managed with a predetermined protocol. Outcome between groups at 1 to 2 years and at more than 3 years was compared. The natural history study, restricted to the inborn population, revealed that posthemorrhagic hydrocephalus developed in 53 of 409 infants with intraventricular hemorrhage. The progression of hydrocephalus either was arrested or regressed in 35 of 53 infants; progression to severe hydrocephalus occurred in 18 of 53 infants. The severe posthemorrhagic hydrocephalus was asymptomatic in 16 of 18 infants. The management and outcome study included both inborn and outborn infants. Of 50 infants, 12 had symptomatic severe hydrocephalus and 38 had asymptomatic severe hydrocephalus. The 16 infants managed with close observation were as likely to remain shunt free as the 22 infants managed with serial lumbar punctures. Of 38 infants, 20 were managed without shunts. At 3 to 6 years, the outcome of infants in the close observation group did not differ from that in the lumbar puncture group. Long-term outcome of infants with progression to asymptomatic severe hydrocephalus did not differ from that of infants in whom disease progression was arrested. Poor outcome in infants with intraventricular hemorrhage and subsequent posthemorrhagic hydrocephalus was related to severity of hemorrhage and gestational age at birth less than 30 weeks. Because long-term outcome of infants with severe hydrocephalus did not differ from that of infants in whom the progression of hydrocephalus was arrested or whose condition improved before hydrocephalus became severe, we currently attempt medical management of these infants.
