Objective.Analysis of the cause of intrauterine death of one fetus of twin and to evaluate the outcome of conservative management of twin pregnancy with single fetal death. Method.A retrospective review was undertaken on PUMC hospital records of women who delivered twin between Jan. 1987 and Dec. 1998. Result.During the recent 12 years

99 pregnant women were documented as twin pregnancies. Of the twin pregnancies during this period

13 were complicated by a single intrauterine death. Four women suffered this complication during their first trimester. In the remain 9 cases one fetus died during second or third trimester. The cesarean section was given in three pregnant women soon after a single intrauterine death because of the survival fetal distress. No consumptive coagulopathy was apparent in all 13 pregnant women. It is wise that the pregnancy was managed conservatively

with regular coagulation parameters obtained. Conclusion.Our results support conservative management in twin pregnancies complicated by single fetal death.
