[Congenital hydrocephalus--an analysis of the course of pregnancy, prenatal studies and labor].

An analysis of the pool of our patients revealed few disturbances during pregnancy. In two cases the malformations were possibly due to drugs. Prenatal sonographic diagnostics were performed in one-third of the cases or documented: in 60% of the investigated cases a hydrocephalus was found, this being only 20% of the whole pool. The major part of the births were performed by Caesarean section, mainly because of a prolongation of the birth directly or indirectly due to the large circumference of the head. The hereditary trait of associated malformations and malformations of the central nervous system was frequent. Therefore, we advocate a better prenatal work-up and a birth by planned Caesarean section.
