Fetal Surgery Maria 23 weeks into Maria Meza’s pregnancy, twins Addison and Addilyn Marquez were diagnosed with a serious condition called twin-to-twin transfusion syndrome. In this rare condition, blood vessels that connect identical twins grow unevenly in the womb, causing one fetus to receive too much blood, and one to get too little. It can be deadly for both infants. Our innovative fetal surgery program was a lifesaver. Ramen Chmait, MD, director of fetal surgery, operated on the girls before they were born. In the delicate, and ultimately successful operation, high-precision laser energy was used to carefully seal off the connection between the blood vessels. Today, the twins are healthy, energetic 1-year-olds! “I have no words to describe the gratitude that I have for Dr. Chmait and the rest of the staff,” says Maria. “I can never repay the gift you have given us. Thank you from the bottom of my heart."
