Understanding Carotid Cavernous Fistula
A carotid cavernous fistula (CCF) is a rare condition. It happens when the carotid artery and the cavernous sinus connect in a way they shouldn’t. There are two main types, each with its own effects on patients.
Definition and Types
CCFs are either direct CCF or indirect CCF. A direct CCF means a direct link between the carotid artery and the cavernous sinus. This usually happens from injuries or aneurysm bursts. Indirect CCF, or dural CCF, has many small connections. It can start on its own or from various causes. Carotid Cavernous Fistula Radiology
Causes and Risk Factors
