Pope Francis came so close to death at one point during his 38-day battle in hospital with pneumonia that his doctors considered ending treatment so he could die in peace, the head of the Pope's medical team said.
After a respiratory crisis on February 28 that left Francis nearly choking on vomit, "there was a real risk that he would not make it," said Sergio Alfieri, a doctor at Rome's Gemelli hospital.
"We had to choose whether to stop there and let him go, or go ahead and push him with all possible drugs and therapies, risking more damage to his other organs," Alfieri told Corriere della Sera in an interview published on Tuesday.
"In the end, we took this route," he said.
The 88-year-old pope returned to the Vatican on Sunday after the most serious health crisis of his 12-year papacy.
He was admitted to the Gemelli hospital on February 14 for a bout of bronchitis that turned into double pneumonia, a particularly serious condition for him, as he had pleurisy as a young man and had part of a lung removed.
The Vatican provided an unusual amount of detail in updates on the Pope's condition during his hospital stay, which included four "respiratory crises" involving serious coughing caused by constriction in his airways, similar to asthma attacks.
