Application analysis of radiofrequency ablation for monochorionic triplet pregnancy

Abstract:

Triplet pregnancies can be divided into various types based on chorionic and amniotic character. Among them， dichorionic triamniotic（DCTA） triplet and monochorionic triamniotic（MCTA） pregnancies have the risk of multiple pregnancies and complications of monochorionic twins due to its monochorionic part. Multifetal pregnancy reduction can improve pregnancy outcomes effectively，and radiofrequency ablation（RFA） is the most commonly performed method. At present，there are few clinical reports on RFA for monochorionic triplet pregnancies and dichorionic triplet pregnancies. This study，through the review of previous studies，has summarized the safety and effectiveness of RFA for triplet pregnancy reduction of DCTA and MCTA，as well as the influence of the timing and indication of reduction on pregnancy outcomes， so as to provide guidance for clinical consultation.
