Total 145 selective termination of complicated monochorionic multiple pregnancies were conducted successfully, 116 through fetal abdomen and 29 through fetal back. 133 procedures were carried out in MC twins and 11 in triplets with a MC pair and 1 MC quadruplet.Figure 1 shows the Color Doppler before and after ablation of the two needle insertion angles.
