Risk of Fetal Loss After Chorionic Villus Sampling in Twin Pregnancy Derived From Propensity Score Matching Analysis

摘要

(Abstracted from Ultrasound Obstet Gynecol 2022;59:162–168) Chorionic villus sampling (CVS) and its procedure-related risk of fetal loss in twin pregnancy have not been investigated in a randomized controlled trial setting. Authors of previous studies have concluded that only investigation of low-risk pregnancies could demonstrate the true effect of CVS.
