[Rupture of a cerebral aneurysm and pregnancy: apropos of a case of neurosurgical intervention during pregnancy].

The authors report a case of an aneurysm of the posterior cerebral artery that was operated on after 28 weeks of amenorrhoea without any sequelae for the mother or the fetus. The article gives precise details of the neurosurgical procedures carried out in this pregnant woman and how and what neurosurgical anaesthesia was administered while the aneurysm was cured and the pregnancy continued. Finally the obstetrical and neurosurgical care is discussed. The neurosurgeons decided on the operation in view of the neurological findings. Once the neurosurgical decision has been made, the obstetrical procedures depend practically on the length of amenorrhoea. Briefly, we would suggest the following: before 31 weeks of amenorrhoea: curing the aneurysm and going on with the pregnancy; after 32 weeks of amenorrhoea: first to carry out a caesarean section and during the same operation to treat the vascular malformation.
