In a statement released to the press, Stone said, "I would like to thank my fans for their love and support and the miraculous power of prayer. I am forever grateful."
The 43-year-old Basic Instinct star was brought to the hospital by her husband, San Francisco Chronicle executive editor Phil Bronstein, on Sept. 30 after suffering severe headaches.
Stone underwent an angiogram and it was determined that the likely cause was a tiny aneurysm that required no treatment.
"Sharon Stone is completely intact neurologically and she will have no medical restrictions on her personal or professional activities," said Dr. Michael Lawton, chief of cerebrovascular surgery at UCSF, in a written statement.
A team of surgeons last week performed an endovascular coil embolization, which involves inserting a catheter in the groin and using it to place a "mass of coils" that blocks blood flow through the artery, Michael Lawton, chief of cerebrovascular surgery at the University of California, San Francisco told The Associated Press.
Doctors feared at first that a weakened blood vessel had burst, but two tests found no such aneurysm, said Berger
An aneurysm is a ballooning-out of the wall of an artery, vein or the heart due to weakening of the wall by disease. It can be caused by injury or an abnormality present at birth and are often caused or aggravated by high blood pressure.
