Objective: To determine the effect of arterio-arterial anastomosis on the umbilical arterial flow in mono-chorionic, di-amniotic twin pregnancy. Subjects: Thirty-three women with mono-chorionic, di-amniotic twin pregnancy. Methods: Pulsed Doppler ultrasonographic examination was performed every 4 we...
