Former Brazilian president Jair Bolsonaro underwent a medical procedure on Saturday to treat recurrent hiccups he has been dealing with for months, according to his medical team.
The 70-year-old ex-president, who is serving a 27-year prison sentence for an attempted coup, had been released from prison on Wednesday to undergo surgery for a groin hernia at the DF Star Hospital in Brasilia.
That surgery was performed on Thursday without incident, and Bolsonaro remained hospitalised for several days for evaluation.
During that time, Bolsonaro's medical team determined it was necessary to perform an anesthetic block of the phrenic nerve – which controls the diaphragm – to treat his recurring hiccups.
The procedure on Saturday "went well", according to another of the doctors, Mateus Saldanha.
Birolini said the process took about an hour, adding that "it's not surgery... it does not involve any incisions”.
The right side of the nerve was treated on Saturday, and a procedure to treat the left side of the nerve is set Monday.
"My love just went to the surgical centre to have his phrenic nerve blocked," former first lady Michelle Bolsonaro wrote in an Instagram post on Saturday. "It's been nine months of struggle and anguish with daily hiccups."
In September, Brazil's Supreme Court found Bolsonaro guilty of conspiring to stay in power after losing the 2022 election to leftist Luiz Inacio Lula da Silva, and handed him a 27-year prison sentence.
The coup failed due to a lack of support from top military brass.
The far-right ex-president has claimed his innocence, claiming that he was being persecuted by the Supreme Court.
Bolsonaro was under house arrest from August until his imprisonment on November 22.
Once discharged from the hospital, Bolsonaro will return to serving his sentence at a federal police jail in the capital.
Brazil's Supreme Court on Saturday also ordered house arrest for 10 officials from Bolsonaro's administration who were involved in planning the coup plot, sought legal justification for it, or spread disinformation about it on social media.
The 10 officials had been convicted but were out of prison due to pending appeals.
One of the officials, Silvinei Vasques, was detained in Paraguay on Friday after he allegedly tried to board a flight with false papers.
