Causes of direct carotid cavernous fistula?

summary

Direct carotid cavernous fistula refers to the rupture of the artery wall of the cavernous sinus segment of the internal carotid artery, which makes it form abnormal arteriovenous communication directly with the cavernous sinus, accounting for 75% - 84% of carotid cavernous fistula. It is more common in trauma or ruptured aneurysm in the cavernous sinus. Causes of direct carotid cavernous fistula? Next, I'd like to share my views with you.

First, the skull base fracture caused by head injury or head crush injury caused by motorcycle traffic accident, especially when the fracture of temporal bone and sphenoid bone affects the carotid artery, the fracture fragments pierce the internal carotid artery wall of cavernous sinus; Or orbital stab injury or shrapnel injury, often a single large break.

Second: percutaneous puncture of trigeminal semilunar ganglion for radiofrequency treatment of trigeminal neuralgia, transsphenoidal sinusotomy for chronic sinusitis, transsphenoidal pituitary tumor resection, Fogarty catheter for internal carotid artery thrombectomy, and temporal posterior trigeminal rhizotomy (Frazier operation) can also cause iatrogenic injury.

Third, about 60% of the spontaneous direct CCSF had lesions in the middle of the internal carotid artery wall, including cavernous sinus internal carotid aneurysms, fibromuscular dysplasia, Ehlers Danlos syndrome type IV, Marfan syndrome, neurofibromatosis, delayed osteogenesis, pseudoxanthomatosis, viral arteritis and primitive trigeminal artery residue.
