High risk pregnancy in a patient with angioma of the corpus callosum.

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.

[Agenesis of the right carotid in a subject with dextrocardia. Diagnostic imaging in 1 case with unique characteristics]. / Agenesia della carotide destra in un soggetto con destrocardia. Imaging diagnostico di 1 caso con caratteristiche uniche.

A man aged 51 with dextrocardia and right common and internal carotid artery agenesis is described. Cerebral blood flow is allowed internally by the left carotid and left vertebral antegrade flow, while right artery has only the function to drain the blood from the left side of vertebral system. A small external right carotid does exist, but it is separated from the cerebral hemodynamics. Diagnosis of dextrocardia was made on the basis of the standard chest X-ray, that of carotid agenesis on the basis of selective digital arteriography, color-Doppler and magnetic resonance. The diagnosis of congenital agenesis was based on the absence of a foramen caroticus and of a canalis caroticus. Large anasthomosis between the left and right side of cerebral system permit a normal perfusion to left cerebral hemispherium and a quite normal life.
