Conjoined Twin Dies After Separation Surgery
12 Jan
Summary
- One conjoined twin died from cardiac arrests during surgery.
- His brother also failed to survive emergency separation surgery.
- The twins shared three legs and were joined at multiple body parts.

Tragically, one conjoined twin, Marcos, has died after experiencing successive cardiac arrests just two days after his birth. His brother, Mateus, subsequently underwent an emergency separation surgery in an attempt to save him. Despite the surgery being technically successful, doctors confirmed that Mateus also did not survive.
The conjoined twins, who were joined at the chest, abdomen, and pelvis and shared three legs, were born on Tuesday in Goiania, Brazil. Their mother, Raylane Siqueira de Oliveira, and father, Maycon Alex Rodrigues, had traveled from their home in Canarana for the high-risk delivery. The couple had previously expressed shock upon learning of the conjoined twins during a routine ultrasound.
This heartbreaking event echoes a previous tragedy in Goiania on Christmas Eve, where another conjoined twin, Aruna Rodrigues, died seven months after a complex separation surgery from her sister Kiraz, who had died shortly after the operation. The same lead surgeon, Zacharias Calil, was involved in both cases, expressing deep sadness and solidarity with the grieving families.
