Abstract:
Objective To investigate selective pregnancy reduction in second-trimester and its notices. Methods Selective pregnancy reduction in 19 cases of multiple pregnancy during 12～25 gestational age was performed,including 6 cases of twins,1 cases of triplets,1 case of quadruplet and 1 case of sextuplet. Ultrasonographically guided transabdominal intracardiac injection of high concentrate potassium chloride (KCl) solution was used. Results Performances of selective feticide in all twins were successful,except one monochorionic twins. In 11 cases of triplets,one case was aborted,one case was monozygotic triplet. Selective feticide was performed successfully in 7 of the rest 9 cases and the quadruplet Two cases were aborted after the procedure. The sextuplet was aborted after feticide. Conclusion Multifetal pregnancy reduction can be successfully performed in the second trimester without severe maternal complications. But abortion might occur afterwards. It is possible to reduce the abortion rate if monozygotic twin or triplet can be excluded before feticide,choosing the gestational sac which near the fundus,reducing the amniotic fluid volume of the target fetus or postponing feticide.
