Midwest Fetal Care Center

Twin-twin transfusion syndrome (TTTS) procedure outcomes

TTTS + MWFCC

The Midwest Fetal Care Center (MWFCC) performed its first fetoscopic laser ablation (FLA) for twin-twin transfusion syndrome (TTTS) in 2008. Led by a team of top medical experts in the field of maternal-fetal medicine and fetal diagnosis and therapy, our program has become one of the highest volume treatment centers for TTTS in the nation and has exceptional outcomes.

Our center performed 132 laser surgeries between July 1, 2017, and Sept. 8, 2021, with 122 delivered and 10 ongoing pregnancies, and an overall survival rate of 86%.

Surgical Outcomes

A summary of Midwest Fetal Care Center’s current clinical outcomes data for the treatment of TTTS is presented here. Our goal is to provide our patients and community the latest TTTS patient outcomes data to support informed decision-making.

We are actively involved in research regarding TTTS and collaborate with other advanced fetal care centers in the U.S. and internationally through the North American Fetal Therapy network (NAFTnet) and the International Fetal Medicine Surgery Society (IFMSS). We submit patient data (with informed consent) to a multi-center collaborative registry hosted by NAFTnet to investigate outcomes of this procedure with the goal of advancing care of families affected by TTTS.
