In a previous study we reported the outcome of 528 trichorionic triplet pregnancies and 167 DCT pregnancies managed expectantly or by fetal intracardiac injection of KCl for ER to twins or singletons [1] . In this study we present the technique and outcome of 22 DCT pregnancies undergoing ultrasound-guided laser ablation of the pelvic vessels of one of the monochorionic twins.
