[Selective foeticidium using YAG laser]

Twin-to-twin transfusion syndrome was found by ultrasound in monochorionic diamniotic twins in week 20. The donor had hydrocephalus and the recipient was normal. Selective foeticide was performed by coagulating the vessels of the umbilical cord of the donor with a YAG-laser. The pregnancy continued without complications and a healthy girl was born in week 34. The birth weight was 2935 g. Psychomotor development was normal at the age of six months.
