Carotid cavernous fistulas (CCFs) are abnormal connections between the blood vessels that take blood to and from the brain:
The integrity of the cavernous sinus and its dura are particularly important because blood is toxic to a number of nearby sensitive neural tissues.
CCFs are classified as either indirect (type A, or dural) or direct (type B, C, and D).
Indirect CCFs are usually spontaneous and have no known cause.

Embolization is a minimally invasive procedure that involves the threading of a small catheter or tube through a blood vessel in the groin, which is then navigated to blood vessels in the brain to create an emboli or block blood flow.
During embolization, small coils or detachable silicon balloons are guided through the arteries to stop the abnormal blood flow to the CCF.
Gamma Knife radiosurgery is a painless treatment that uses hundreds of highly focused radiation beams to target tumors and lesions within the brain, with no surgical incision.
As the nation's leading provider of Gamma Knife procedures, UPMC has treated more than 12,000 patients with tumors, vascular malformations, pain, and other functional problems.
