Abstract

Simultaneous transabdominal injection of potassium chloride (KC1) assisted by transvaginal ultrasonographic guidance was evaluated in 5 patients who conceived due to various assisted reproductive techniques and ovarian stimu-lation. All 5 underwent first-trimester fetal reduction for multiplicity of high- order pregnancies. Four sets of triplets were reduced to twin, and 1 twin pregnancy was reduced to a singleton. Less than 2 ml of 2 mEq/ml KC1 per fetus was needed for each case. No fetal or maternal complications nor technical failure attributable to the procedure were recorded. All pregnancies were delivered ≥35 weeks of gestation. Transabdominal fetal reduction using simultaneous transvaginal ultrasonographic guidance for selective feticide combines the benefits of both the transabdominal and transvaginal approaches, mainly in selected cases in which some experts prefer the abdominal route, but find it technically difficult to practice. Further experience is needed to confirm our encouraging preliminary results before drawing any definitive conclusions.
