Multifetal pregnancy reduction: a Belgian experience.

Multifetal pregnancy reductions were performed during the first trimester of pregnancy in 26 patients. Transabdominal intrathoracic KC1 injections were performed in 23 cases, and transcervical aspirations in 3 cases. There were 4 miscarriages (15%) during the second trimester, 18 pregnancies ended in 33 births, 4 pregnancies are going on uneventfully and are beyond 32 weeks. There was no maternal morbidity related to the procedure; fetal morbidity has been mild.
