Direct Carotid Cavernous Fistula

Direct carotid-cavernous fistulas (CCFs) secondary to a ruptured intracavernous carotid aneurysm (ICCA) are usually high-flow lesions. On very rare occasions, a ruptured ICCA may present as a low-flow CCF, which poses a diagnostic and therapeutic dilemma whether the aneurysm and the observed fistula are causally related. Herein, we describe a rare case in which a ruptured ICCA resulted in a low-flow CCF. We demonstrated our approach to clarify this clinical scenario, and also propose a possible pathomechanism to explain the existence of low-flow direct CCF.

Background. Carotid-cavernous fistulas are abnormal communications between carotid arteries or their branches and the cavernous system caused mostly by trauma. Posttraumatic fistulas represent 70% of all carotid-cavernous fistulas and they are mostly high-flow shunts (type A). This type gives characteristic eye symptoms. Case report. This paper presents a 44-year old male patient with carotidcavernous fistula as a result of penetrating head injury. In clinical presentation the patient had exophthalmos, conjunctival chemosis and weakening of vision on the right eye, headache and diplopia. Digital subtracted angiography showed high-flow carotid-cavernous fistula, which was vascularised from the left carotid artery and from vertebrobasilar artery. Endovascular embolization with platinum coils was performed through the transarterial route (endoarterial approach). Check angiogram confirmed that the fistula was closed and that no new communications developed. Conclusion. Embolization of complex carotidcavernous fistula type A was successfully performed with platinum coils by endovascular approach.

Stenting Procedure

We describe an unconventional endovascular approach in a young patient with large high-flow traumatic carotid cavernous fistula that could not be treated by detachable balloon procedure. Two coronary stent-grafts were used to close the large tear of internal carotid artery. After the failure of stenting procedure, the fistula was successfully treated by trapping with two detachable balloons.

We encountered 8 cases of high-flow and direct carotid cavernous fistula (CCF) since 1994. Four patients were treated with transarterial fistula occlusions using detachable balloons before 1997. Complete obliteration of CCFs with preservation of internal carotid artery (ICA) were achieved in all 4 cases using each one balloon. Three cases were approached to the fistulas via the percutaneous transfemoral approach, but one aged patient needed a direct carotid puncture because of her tortuous vessels. Meanwhile, transvenous embolizations with detachable coils (DCs); Guglielmi detachable coil (GDC), interlocking detachable coil (IDC) and fibered platinum coil were attempted in four cases after 1997; in 2 cases after failure of transarterial approach and in 2 as initial form of treatment. All 4 cases were successfully approached to the cavernous sinuses (CS) through the inferior petorosal sinus (IPS). At first we intended to block dangerous outflow points for the superior ophthalmic vein (SOV), cortical venous reflux (CVR) and contra-lateral CS. And then obliteration of the fistulas were performed with tight packing of GDCs covering the outside of the ICA. At this time, the arteriovenous shunts were disappeared abruptly, so we finished all procedure without occlusion of IPS. We compared the two methods and concluded that the transvenous embolizaton with DCs is an useful alternative of transarterial detachable balloon therapy of high flow CCF, especially when transarterial approach is difficult or proper balloons are not available.

Direct Carotid Cavernous Fistula

The development of a high-flow carotid-cavernous fistula from the rupture of a large cavernous aneurysm successfully embolized by coils is rare. A 50-year-old male patient developed a high-flow carotid-cavernous fistula 48 hours after successful coiling of a large left cavernous aneurysm, presumably due to rupture of a focal dissection at or close to the neck of the aneurysm. He initially responded to daily self-compression of the left common carotid artery, but the fistula recurred. After failing to approach the fistula site via transvenous route, balloon trapping of the internal carotid artery was planned. Prior to its placement for functional occlusion test, the detachable balloon slipped into the fistula site and occluded it. It was thereafter detached in this position. The sequence of events, a large cavernous aneurysm spontaneous ruptured after coiling, suggested dissecting process or disease. We address in the report the complexity of the endovascular management of this rare association.

Balloon Occlusion Technique

A 62-year-old man with a traumatic high-flow right carotid-cavernous fistula was treated by transarterial balloon occlusion technique. However, because of the relatively small size of the fistula, the balloon could not enter into the cavernous sinus via the fistula. During the procedure, the shunt flow decreased significantly, and we stopped the procedure. Follow-up angiography performed 14 days after the procedure showed complete occlusion of the fistula with a small residual pseudoaneurysm. One year later, the pseudoaneurysm had decreased in size. Repeated transient decrease and stagnancy of blood flow at the fistula during the balloon procedure may have played an important role in the thrombosis in this patient.
