Recently, selective termination is employed in multifetal pregnancies, in the presence of an abnormal fetus, or in the complication of twin pregnancies. The purpose of this study is to evaluate effectiveness, safety of the tailored selective termination in multifetal pregnancies. METHODS: This study was retrospective and involved six cases. Indication of termination were 3 cases of structural anomalies (anencephaly, encephalocele, body stalk anomaly), 1 case of chromosomal anomaly (21 trisomy) and 2 cases of monochorionic twin complications (acardiac twin, twin to twin transfusion syndrome). RESULTS: We used KCL injection in 4 cases, they were all confirmed dichorionic twin, and in 2 cases of monochorionic twin, we used alcohol ablation of intra-abdominal umbilical artery in 1 case, and radiofrequency ablation of the cord in 1 case. CONCLUSION: All procedures were successful, and all normal infants were delivered in 3rd trimester. Tailored selective termination in 2nd trimester is effective and safe in abnormal multifetal pregnancies.
