  • Duralne karotiko-kavernozne fistule = Dural carotid-cavernous fistulas
    Cvenkel, Barbara ; Dolenc, Vinko V. ; Miloševič, Zoran
    Background. Dural carotid-cavernous sinus fistulas (CCF) communications fed bymeningeal branches of the intracavernous internal carotid artery (ACI) or/and external carotid artery (ACE). In contrast ... to typical CCF, the arteriovenous shunting of blood is usually low flow and low pressure. Spontaneous dural CCF are more common in postmenopausal women. Aetiology is unknown, but congenital malformation or rupture of thin-walled dural arteries within venous sinuses is believed to be the cause. Case reports. 3 cases lacking the typical clinical signs of CCF who had been treated as chronic conjunctivitis, myositis of the extraocular muscle and orbital pseudotumour are presented. Clinical oresentation depends on the direction and magnitude offistular flow and on the anatomy of the collateral branches. If increased blood flow is directed anteriorly in ophthalmic veins the signs of orbito-ocular congestion are present ("red-eyed shunt syndrome"). Drainage primarly in the inferior petrosal sinus may cause painful oculomotor and abducens palsies without signs of ocular congestion ("white-eyed shunt syndrome"). Also different therapeutic approaches as well as possible complications are described. Conclusions. For definite diagnosis angiography is obligatory and is also therapeutic as one third to one half of dural CCF close spontaneously. Because of potential severe eye and systemic complications, surgical intervention is indicated only in cases with uncontrolled secondary glaucoma and hypoxic retinopathy.
