Acute polyhydramnios complicating monozygous twin pregnancies--case report.

Two cases of acute polyhydramnios complicating twin pregnancies were treated with repeated amniocentesis for the relief of extreme abdominal discomfort and to prevent imminent premature labor. The procedure was found to be safe and resulted in prolonging the pregnancies by 14 to 11 days respectively. This management, with the addition of tocolysis and close fetal surveillance (which resulted in 2/4 living children) can offer some hope in an otherwise hopeless situation.
