The Siena University Hospital has released an update on the condition of Alex Zanardi - the former Formula 1 driver remaining in intensive care following a road accident on Friday.
Zanardi had been competing in a handcycling event on Friday, when he was involved in an accident with a 'heavy vehicle'.
The 53-year-old Italian was airlifted to hospital where, upon arrival, he underwent a two-and-a-half hour surgery.
An update from the hospital on Saturday morning read:
“The Health department of Siena AOU informs that the patient underwent a delicate neurosurgery on the evening of 19 June, and was subsequently transferred to the ICU, has stable metabolic and haemodynamic parameters.
“He is intubated and supported by artificial ventilation while the neurological picture remains serious.”
Zanardi, who has become a successful Paralympic athlete since losing both his legs in a 2001 CART accident, competed most famously for Williams in the 1999 Formula 1 season.
