Mariana, who was supposed to have represented Brazil at the Miss World beauty pageant was diagnosed with a urinary infection and the doctors had to amputate both of her hands and feet in order to save her vital organs. A difficult infection caused septicaemia, which clogged her veins and cut of f circulation.
Mariana was admitted at the Intensive Care Unit of the Brazilian Doria Silva hospital. After she had her hands and feet amputated on Tuesday, Mariana has to have additional surgery on Wednesday, urgently.
