What are the main clinical signs of direct carotid cavernous fistula?
Signs and symptoms Direct carotid-cavernous fistulas are characterized by the triad of pulsatile proptosis, chemosis, and intracranial whistling. There is severe conjunctival congestion, hemorrhagic chemosis, ptosis, and pulsatile proptosis accompanied by a whistling.
What causes carotid cavernous fistula?
Carotid cavernous fistula (CCF) results from abnormal communication between previously normal carotid artery and cavernous sinus. The most common (70%-90%) etiology of direct CCF is trauma from a basal skull fracture resulting in tear in the internal carotid artery (ICA) within the cavernous sinus.
How is a carotid cavernous fistula diagnosed?
Carotid cavernous fistulas can be diagnosed by imaging studies such as: CT scan. MRI scan. Angiogram.
Is carotid cavernous fistula an emergency?
Introduction. A carotid-cavernous sinus fistula (CCF) is a rare condition well known in the neurosurgical field, but not well published in emergency medicine literature. Whether post-traumatic or spontaneous in nature, the symptoms related to CCFs are insidious and potentially severe.
What causes cavernous sinus fistula?
This type is sometimes also called trauma carotid cavernous fistula. It is a hole or tear in a branch of your carotid artery inside the cavernous sinus. This tear is called a fistula, and it is usually caused by accident or injury, including: Being hit in the head.
What is sinus and fistula?

Can you live with fistula?
Although fistulas are associated with IBD, they can occur several years before the condition is diagnosed. While rarely life-threatening, fistulas can decrease people’s quality of life and often need combined medical and surgical treatment.
What is carotid cavernous fistula?
Carotid-cavernous fistula (CCF) is an abnormal connection between the carotid artery and/or its branches and a large vein called the cavernous sinus. The cavernous sinus is located behind the eye and receives blood from brain, orbit, and pituitary gland.
How is CC fistula treated?
Carotid Cavernous Fistula Treatment
- Clipping the fistula. Surgery is an option for some fistulas.
- Fistula ligation. This procedure uses a stitch to tie off the artery and stop the blood flow.
- Radiosurgery. This treatment is surgery that uses radiation to close the fistula.
- Endovascular embolization.
