Spontaneous remission of double pulsatile umbilical venous flow in twin-twin transfusion syndrome: a case report.

Abstract
Double umbilical pulsatile venous flow is a rare event generally associated with fetal right heart failure. We observed, at 21 weeks' gestation, this venous flow pattern in a case of twin-twin transfusion syndrome occurring in the recipient twin affected by severe hydrops. In spite of a spontaneous remission of fetal hydrops at 30 weeks, the fetus died suddenly in utero, 2 weeks later. We hypothesized that this unexpected event was related to reversed acute twin-twin transfusion, and concluded that fetal hydrops remission in twin-twin transfusion syndrome must not be considered as a reassuring prognostic index but as an indication of the need for continuing biophysical monitoring.
