Maternal cerebral circulation in normal and abnormal pregnancies

Background. Abnormal pregnancies are usually associated with an impairment of maternal cerebral circulation which is mainly a consequence of generalized vasospasm and cerebral edema. The pathogenesis of vasospasm has still been a matter of controversy. The aim of this study was to evaluate maternal cerebral blood flow velocity (CBFV) changes in normal and abnormal pregnancies, and to correlate CBFV findings with the severity of symptoms in abnormal pregnancies.
