Calixto had travelled 2,000 kilometres (1,250 miles) from her home in Cuiaba to see the surgeon to the stars.
But following the controversial injection of acrylic glass filler, Calixto started feeling ill. Upon arriving at hospital on Sunday, she was suffering from a racing heart-beat and hypertension, and after four heart attacks she died.
Soon after, Furtado disappeared and is now wanted for homicide and criminal association, while his girlfriend, who some media claim was also his assistant, has been detained.
The news has caused shock waves throughout the industry – Brazil is second only to the United States for the number of plastic surgeries carried out.
The Brazilian Plastic Surgery Society (SBPC) was quick to denounce Furtado, saying "the growing invasion of non-specialists in the specialty has provoked more and more fatalities like this one."
"You cannot perform plastic surgery inside an apartment. Many people are selling a dream, a fantasy to patients in an unethical way and people, weakened, are often attracted to low prices, without considering whether or not the conditions are adequate," SBPC president Niveo Steffen told AFP.
