Background on Angelina and Angelica Sabuco's Surgery
- Most conjoined twins do not survive pregnancy. The occurrence of conjoined twins is estimated to range from 1 in 50,000 births to 1 in 100,000 births worldwide, and the overall survival rate is approximately 25 percent.
- Separation surgery is performed in the United States about six times per year.
- Angelina and Angelina were classified as thoraco-omphalopagus; they were joined at the chest and abdomen. Their livers, diaphragms, sterni (breast bones), chest and abdominal wall muscles were fused. They had separate hearts, brains, kidneys, stomachs and intestines.
- This was the sixth separation of conjoined twins for lead surgeon Gary Hartman, MD.
- This was the second set of conjoined twins separated at Packard Children’s. Yurelia and Fiorella Rocha-Arias were separated at the hospital in November 2007.
