BACKGROUND AND PURPOSE Simultaneous traumatic carotid-cavernous fistulas(TCCFs) and traumatic cerebral aneurysms (TCAs) of the internal carotid artery (ICA) are rare. We describe the pitfalls of detecting a TCA before TCCF occlusion and the endovascular management of the TCA and TCCF. METHODS Over 12 years, 156 patients with TCCFs were treated at our institute. In four men (mean age, 34 years), associated TCAs were detected before (n = 1) or after (n = 3) endovascular occlusion of the TCCFs. Causes for the missed detection of the TCA before TCCF occlusion were masking by a parent artery and fistula drains (n = 1), steal phenomenon (n = 1), and a latent period (n = 1). The TCAs were in the supraclinoid ICA (n = 3) or the paraophthalmic artery (n = 1). Three TCAs were treated with the endosaccular placement of electrodetachable coils. RESULTS Two TCCFs and associated TCAs were successfully occluded with preservation of the ICA. The paraophthalmic TCA was treated with coil occlusion of the TCA and TCCF. Spontaneous fatal rupture of the TCA occurred in one patient after subtotal TCCF occlusion. No notable procedure-related complication was observed in the other three patients. CONCLUSION TCAs may be difficult to detect before treatment of the TCCF because it may be overlooked, a latent period may occur, flow may be shunted, or they may be masked by a nearby parent artery or fistula drains. As soon as a TCA is found, endovascular management should be initiated promptly.

The location of the original sites of the lesions was studied in 22 non-traumatic and 21 traumatic intracavernous carotid aneurysms in which the neck of the aneurysm was confirmed, and also in 23 traumatic carotid-cavernous fistulas in which the location of the fistula was identified. In the cavernous sinus, common sites of non-traumatic and traumatic carotid aneurysms as well as traumatic caro...

BACKGROUND Endovascular embolization represents the method of choice for the treatment of carotid-cavernous fistulas (CCFs). METHODS We report our experience using the endovascular technique in 24 patients harboring 25 CCFs treated between October 1994 and April 2010, with an emphasis on the role of detachable balloons for the treatment of direct CCFs. RESULTS Of the 16 patients who present...

Endovascular targeted coil embolization using dual vessel approach for traumatic direct carotid- cavernous fistula following severe head trauma: technical notes

Direct carotid cavernous fistulas (dCCFs) represent different entitles from spontaneous cavernous sinus (CS) dural arteriovenous fistulas (CSAVFs). Traumatic dCCFs are direct arteriovenous communications between the internal carotid artery (ICA) and cavernous sinus, resulting from a traumatic tear of the horizontal or posterior ascending intracavernous segment of the ICA by skull fracture fragm...
