Unilateral Direct Carotid Cavernous Fistula Causing Bilateral Ocular Manifestation
نویسندگان
چکیده
Unilateral carotid cavernous fistula presents with ipsilateral ocular findings. Bilateral presentation is only seen in bilateral fistulas, usually associated with indirect (dural) carotid cavernous fistulas. Direct carotid cavernous fistulas are an abnormal communication between the internal carotid artery and the cavernous sinus. They typically begin with a traumatic disruption in the artery wall into the cavernous sinus, presenting with a classic triad of unilateral pulsatile exophthalmos, cranial bruit and episcleral venous engorgement. We report the case of a 38-year-old male with traumatic right carotid cavernous sinus fistula and bilateral ocular presentation successfully treated by interventional neuroradiology.

Direct fistulas between the internal carotid artery and the cavernous sinus are mostly posttraumatic and are due to laceration of the carotid siphon or rupture of its intracavernous branches (1]. The fistula is usually unilateral but can be bilateral [1 , 2]. In general , only one communication occurs betwe~n the carotid siphon and the cavernous sinus, as was shown in a large number of cases wh...

متن کاملCarotid cavernous fistula in a patient with Graves' ophthalmopathy.
The clinical manifestations of carotid cavernous fistula, an abnormal arteriovenous connection between the cavernous sinus and the carotid artery, can closely mimic the cardinal signs of Graves' ophthalmopathy, an inflammatory disorder of the orbit usually associated with autoimmune thyroid disease. Therefore, carotid cavernous fistulas are generally considered in the differential diagnosis of ...
متن کاملCarotid cavernous fistula: embolization via a bilateral superior ophthalmic vein approach.
We report the case of a 74-year-old woman with a complex indirect (Barrow D) carotid cavernous sinus fistula. The patient was treated incrementally and finally cured by a rarely reported bilateral retrograde direct transvenous approach via the superior ophthalmic vein. The treatment of the complex carotid cavernous fistula with multiple bilateral fistula points showed additional complexity due ...
متن کاملCarotid cavernous fistula due to a ruptured intracavernous aneurysm of the internal carotid artery: treatment with selective endovascular occlusion of the aneurysm.
Intracavernous carotid artery aneurysms causing a carotid-cavernous fistula (CCF) are rare. These aneurysms usually cause neurological symptoms due to gradual expansion without rupture. If they do rupture they most often lead to a CCF instead of bleeding into the subarachnoid space. A patient is described with a ruptured intracavernous aneurysm causing a CCF resulting in acute onset of unilater...
