title: The acardiac twin: a case report using color Doppler ultrasonography.
abstract: The use of color Doppler sonography has expanded our understanding of the normal and abnormal pregnancy. A case is presented here in which color Doppler imaging was utilized to confirm a long-held theory concerning the strikingly abnormal dynamics of arterial flow to an acardiac twin and observations are also presented concerning the possible route of venous return contrary to presumed theories established within the literature.
