Recently, twin pregnancies have increased. Selective feticide was proposed to achieve a good outcome of pregnancy. This study aimed to evaluate the performance of feticide in twin pregnancy with fetal anomaly.  \nMethods: This was a retrospective study enrolled from 2009 to 2018. A total of 68 pregnancies with fetal anomalies received feticide. Potassium chloride was injected into the left ventricle to induce fetal asystole. Maternal and fetal characteristics of 16 dichorionic twins were documented to compare before and after 24th gestational week.  \nResults: All pregnant women received feticide without any maternal or fetal complication. The reasons for choosing feticide were divided into four groups, including morphologic defect (61 .8%), genetic-chromosomal abnormality (30 .9%), obstetrical complication (5 .9%), and maternal request (1 .5%) . Mean gestational age at delivery was significantly higher in dichorionic twins who underwent selective feticide before than after 24th gestational week (36 .7 vs 33.4, p = 0.04) .  \nConclusion: Intracardiac injection of potassium chloride was effective for feticide and safe for mothers and fetuses. Selective feticide served as an alternative approach for twin pregnancy with fetal anomaly after sufficient discussion.  \nKeywords: Dichorionic twin; Feticide; Fetal anomaly; Late trimester; Potassium chloride  \n1. INTRODUCTION  \nThe gradual evolution of high-resolution ultrasound sonography (US) and prenatal diagnostic technique has assisted in the early diagnosis of fetal abnormality. However, certain diseases are lately identified in the second or third trimester. Induced feticide is necessary for avoiding the termination of pregnancy with a viable fetus.1 Feticide refers to causing the death of a fetus, which is generally conducted prior to mid-to late-second trimester of pregnancy. Parents could opt for feticide before termination of pregnancy to relieve themselves of the unwarranted legal, financial or emotional burden.  \nIn recent years, the number of twin pregnancies has increased gradually, and more complications have been observed in mothers and fetuses.2 Twin pregnancy achieved a higher rate of chromosomal or structural abnormality than a singleton pregnancy.3 Therefore, selective feticide is considered a way to avoid giving  \n*Address correspondence.
