Multiple Pregnancy Clinical Trial
Official title:
Early Fetal Reduction Through a Transvaginal Ultrasound Guided Approach in Multifetal Pregnancies: Mechanical Disruption Against Potassium Chloride Injection. A Randomized Controlled Trial
In this study multifetal pregnancy reduction (to twins) will be carried out through a transvaginal route, at an early gestational age (6 weeks - 9weeks + 6days) using 2 methods: mere mechanical disruption against potassium chloride injection. The 2 methods will be compared regarding the efficacy, complications and pregnancy outcome.
The incidence of multifetal gestations has increased dramatically over the past several decades. Multiple pregnancies are frequently complicated by maternal and fetal morbidities and mortalities. Data show that the incidence of morbidity and mortality correlate with fetal number. In the United Kingdom, the single embryo transfer policy has reduced the incidence of multifetal gestation. Also, in the United States the ASRM (American society of reproductive medicine) has revised the guidelines to optimize the number of transferred embryos during IVF. However in Egypt, transfer of 3 to 4 embryos is still practiced. The procedure of fetal reduction aims to decrease the occurrence of maternal and perinatal morbidities related to multifetal gestations. It can be carried out transvaginally or transabdominally under ultrasound guidance. It may be done by potassium chloride injection through needle injection, mere mechanical disruption by a needle, or by radiofrequency ablation. In this study multifetal pregnancy reduction will be carried out through transvaginal route, at an early gestational age (6 weeks - 9weeks + 6days), and compare the efficacy, complications and pregnancy outcome using mere mechanical disruption against potassium chloride injection. ;
