Diego Maradona was taken to a hospital in La Plata, Argentina on Monday for anemia and dehydration.
He was then taken to a hospital in Buenos Aires and early on Tuesday his personal doctor said his condition had improved.
But later on Tuesday, the blood clot in the brain was discovered on X-ray and it was decided to operate.
The procedure, which posed a risk due to Maradona's general health, lasted 80 minutes.
Prior to the operation, the doctor Leopoldo Luque, who was also the one who performed the operation, had said that it was a routine operation.
- The next step is observation, but it is controlled.
Then it depends on how he recovers.
It is not very complicated, but it is after all brain surgery, says Luque.
About 50 fans had gathered outside the hospital in Buenos Aires and when the news spread that the operation had gone well, it was celebrated and they shouted "Diego!
Diego! ”
The Argentine has previously suffered two heart attacks and he has also had liver problems.
Diego Maradona is now the coach of the Argentine Gimnasia y Esgrima.
He met the players at the team's training facility in connection with his 60th birthday last Friday, but is said to have had major problems walking and stayed for only half an hour.
