Felipe Massa has expressed his gratitude to Budapest's AEK hospital, which treated him after his horror accident at the Hungarian Grand Prix.

"I am convinced that the speed and the quality of the treatment I received at the AEK hospital was fundamental to reducing the duration of my convalescence," the 28-year-old, who is now recovering in Brazil, wrote in an email read out at a ceremony in Budapest on Monday.

A representative from the Brazilian sports ministry, Ricardo Leyser Goncalves, also thanked Hungary for the "attentive and professional" care that Massa had received in Budapest.

"Thanks to the professional excellence and the kindness (of the staff), this story has had a good ending," Goncalves said at the event, noting the shock felt in Brazil after the fatal accident of Ayrton Senna in 1994.

"All of Brazil could relax that Felipe Massa was in good hands," he added.

Formula One boss Bernie Ecclestone also expressed his gratitude for the "super hospital" in an email, remarking that "if I have an accident, I want to be taken to AEK."

Massa suffered severe head injuries when he was struck at around 250 km/h by a spring that flew off compatriot Rubens Barrichello's Brawn car during qualifying for the Hungarian Grand Prix on July 25.

The driver underwent surgery on his fractured skull and was flown to Brazil after nine days of convalescence at the AEK hospital.
