Doppler sonographic demonstration of arterio-venous anastomosis in monochorionic twin gestation.
Arterio-venous connections, which are known to occur in monochorionic twin placentae and are a mechanism for the development of twin-to-twin transfusion syndrome, can be demonstrated in utero by means of targeted sonography with the use of spectral and color flow Doppler techniques.
