[Anesthesia for nonobstetric surgery during pregnancy: cerebrovascular disease].

The incidence of intracranial hemorrhage is approximately 1-5 in 10,000 pregnancies. In Japan, it is reported that 184 such cases occurred and 10 of them died in 2006. Neurosurgery during pregnancy is required infrequently however a multidisciplinary approach is mandated and anesthesiologists need to modify neuroanesthetic and obstetric practices to accommodate the safety requirements of the mother and fetus. Following the physiologic changes of pregnancy and fetal considerations in nonobstetric surgery during pregnancy, we present the maternal and fetal considerations in anesthesia for intracranial hemorrhage.
