The Brianna Marie Foundation has sponsored Dr. Quintero and his team in the conduction of outcome studies on complicated monochorionic multiple pregnancies. We completed phase one of this trial in December 2015 and began phase two in June 2016. The final report was submitted for journal submission in August 2017 and estimated to be published fully in late 2017.The purpose of these studies is to assess the merits of different management options in these complicated pregnancies. While antenatal expectant or medical management may be of help in some of these pregnancies, in utero endoscopic surgery (also known as FETAL THERAPIES/ SURGERIES) may be warranted in others to offer the babies a better chance to survive and to have a better quality of life. An assessment of the outcomes of such pregnancies will allow Dr. Quintero and his team to share with the rest of the scientific community the achievements and potential shortcomings of such surgeries long term.
