BUENOS AIRES, Oct. 8 (Xinhua) -- Argentine President Cristina Fernandez underwent successful surgery Tuesday to treat brain hematoma, the presidency's spokesman said, based on the first medical report on the outcome.
"The surgery was satisfactory without complications, it went very well," said Fernandez's spokesman Alfredo Scoccimarro in a statement. "She thanked her medical team and all the people who prayed for her. She is in a very good mood."
The next medical report will be issued Wednesday, the spokesman added.
The operation, which lasted almost two hours, took place Tuesday morning at the Favaloro Foundation's University Hospital, in the capital Buenos Aires.
The office of the presidency also released the medical report on its website.
Due to the operation, the powers of the presidency were transferred Monday, for a 30-day period, to Vice President Amado Boudou.
Fernandez's hematoma, swelling caused by a collection of blood, is believed to have been caused by an Aug. 12 head injury.
Outside the hospital, supporters of the ruling party gathered to express their support for the president.
