Twin-twin Transfusion Syndrome: Olivia and Stella's Story

Five-year-old identical twins Stella and Olivia DeFilippis are full of giggles, and love to make each other laugh.

The girls delight in the fact that almost everyone they meet has a hard time telling them apart. But before they were born, there was a very significant difference that meant a life or death situation for one or both of the twins.

Olivia and Stella were diagnosed in utero with twin-twin transfusion syndrome (TTTS), a life-threatening condition in which blood circulates unequally between the twins. One baby receives too much blood and nutrients, while the other doesn't get enough.

Their parents, Trista and Chris, turned to The Children’s Hospital of Philadelphia where a team of fetal medicine experts had extensive experience treating TTTS. Trista and the twins underwent a minimally invasive fetal surgery procedure called fetoscopic laser ablation to disconnect the communicating blood vessels and stop the unequal flow of blood. The goal is to halt the progression of TTTS.
