Spontaneous umbilical flow cessation in an acardiac fetus may optimize outcomes for the normal twin.
Case Report (n=1)
Reports a rare case of spontaneous cessation of umbilical blood flow in an acardiac fetus, discussing management to optimize outcomes for the normal twin.

Suggests expectant management may suffice in select acardiac twin cases; leaves open identification of predictors for spontaneous cessation.
The acardiac fetus is a rare entity found only in monozygotic multiple pregnancy. Although the acardiac fetus is non-viable, the perinatal mortality rate for the normal fetus may be as high as 50 per cent, and is usually associated with fetal heart failure and hydrops fetalis, or as the result of prematurity. In this communication, we describe a case of spontaneous cessation of blood flow to an acardiac fetus and discuss the management of this condition with special reference to optimizing the outcome for the normal fetus.

Cox et al. (1992) conducted a case report in Acardiac fetus in a twin pregnancy (n=1). Spontaneous cessation of umbilical blood flow was evaluated. Spontaneous cessation of umbilical blood flow occurred in an acardiac fetus of a twin pregnancy, highlighting a rare natural course that may optimize the outcome for the normal fetus.
