Heloísa and Helena Batista da Silva, two-year-old conjoined twin sisters from Roraima, Brazil, died just 14 minutes apart after suffering cardiac arrests during a grueling 15-hour separation surgery, according to hospital medical staff. The procedure marked the fifth and final operation for the toddlers, who were born craniopagus—a rare condition where twins are joined at the head, sharing brain tissue and blood vessels—occurring in approximately one out of every 2.5 million live births worldwide.
Medical Background and Previous Procedures
For the past two years, the sisters were monitored by a specialized medical team at a Brazilian hospital, representing the third set of craniopagus twins treated at the facility. Over the preceding year, the toddlers had successfully completed four prior surgeries. According to hospital records, the first three procedures successfully separated 75 percent of the shared brain tissue and blood vessels. During the fourth operation, doctors utilized tissue expanders to increase the skin necessary for closing the children’s skulls ahead of the final separation.
More than 50 medical and support staff members participated in the multi-hour final intervention. The nation’s public healthcare system fully funded all treatments, sparing the family any financial cost.
Surgical Complications and Cause of Death
Shortly after surgeons successfully separated the sisters, their conditions rapidly deteriorated. According to the medical team, the youngsters suffered haemodynamic instability, which describes insufficient blood flow to vital organs that can trigger multiple organ failure. During the crisis, one twin developed low blood pressure while the other experienced high blood pressure. Both girls suffered cardiac arrests just 14 minutes apart. Doctors attempted resuscitation for 25 minutes before pronouncing them dead.
Jayme Farina Júnior, a plastic surgeon on the medical team, explained that the children had endured chronic illness throughout their lives, leaving their physical systems severely weakened. “They had many bouts of pneumonia, they had a tracheostomy, they needed a gastrostomy for feeding, and they had episodes that also weakened their bodies,” Dr. Farina Júnior stated. “But at the moment of the final separation, their bodies could not withstand this instability, and then they progressed to cardiac arrest.”
Family Response and Burial
The day following the surgery, the sisters were laid to rest near their family home. Amarildo Batista da Silva, the girls’ father, publicly thanked the hospital staff and doctors who attempted to save his daughters, emphasizing that he holds no blame toward the medical team.
“Every child you lose is a defeat, every child you manage to save is a victory,” the father stated. “I am sure you have far more victories than defeats, so this does not become a defeat.”
Did You Know?
Craniopagus conjoined twins represent an extremely rare medical phenomenon. The vast majority of these infants are either stillborn or pass away within the first 24 hours of life. According to current medical data, survival rates for separating twins with this specific condition range between 50 and 60 percent for at least one twin.
Frequently Asked Questions
What is craniopagus conjoined twins?
Craniopagus twins are joined at the head, sharing brain tissue and blood vessels.
How rare is the condition?
According to medical data, craniopagus births occur in approximately one out of every 2.5 million live births globally.
What causes mortality during separation surgeries?
As noted by treating physicians, severe haemodynamic instability, blood pressure fluctuations, and cardiac arrest stemming from weakened physical constitutions present critical risks during complex neural separation procedures.
