A case of monochorionic‐diamnionic twin was diagnosed as feto‐fetal transfusion at 19 weeks gestation. We performed amniocentesis to reduce the fluid and amnioseptostomy. The discodancy of amniotic fluid was remarkably dissolved for long period. At 25 weeks gestation, we started tocolysis by ritodrine and magnesium sulfate drip infusion. During the uterine contraction, we detected increased preload index on recipient fetus by evaluation of the flow of inferior caval vein and reverse end‐diastolic flow of umbilical artery on donor fetus and these unfavorable findings disappeared a few minutes after the uterine contraction improved. These findings suggest that uterine contraction is absolute risk factor for feto–fetal transfusion syndrome because they worsen blood flow on both fetuses. (1) Kanzaki T, Chiba Y.
