Two-year-old conjoined twin girls, Heloísa and Helena Batista da Silva, die during or shortly after their fifth surgery to separate them, which takes place on August 15. The reports say the operation ends with fatal complications while the twins are on the operating table.

The case is presented as the latest in a series of prior attempts to separate the twins, described as involving earlier surgeries. The outlet reporting the story characterizes the August operation as the twins’ final separation surgery, underscoring the persistence of medical efforts despite repeated challenges. Details on the specific medical cause of death or the nature of the complications are not provided in the supplied accounts.

Across the available sources, the emphasis is the same: the twins are conjoined, the separation surgery is the fifth attempt, it occurs on August 15, and the girls die during the procedure. With only these two entries provided, there are no meaningful differences in reported facts or interpretations to reconcile.
