Literature data indicate that rupture of arterovenous malformations is 4 times more frequent in pregnant women. The Authors present a case of cerebral hemangioma of the third medium anterior of the corpus callosum diagnosed in a patient at the 28th gestational week by Magnetic Resonance scan. The patient underwent elective caesarean section under peripheral anesthesia (peridural and spinal block by Bupivacaine) and delivered a male infant 4560 gr, 52 cm. The postoperative course was uneventful. The arterovenous malformation constituted an important anesthesiologic risk factor but the Authors conclude that caesarean section can be safely performed with a very careful anesthesiological time schedule and a reliable haemodynamic monitoring.
