          Abstract

          Aims

          Carotid-cavernous fistulas (CCFs) are abnormal communications between the carotid arterial system and the cavernous sinus that occur mainly in elderly. Occasionally, treatment of indirect CCFs with conventional endovascular approach through large veins or the inferior petrosal sinus may not be possible. In these cases, a direct surgical cut down on to the superior ophthalmic vein (SOV) is necessary. We describe three such cases of embolization of CCFs through SOV, and their results.

          Methods

          A retrospective case notes review of treated patients over the past 10 years in one tertiary center constituted our methodology.

          Results

          The fistulas in two cases were successfully coiled with complete obviation of symptoms and signs. The third case was complicated due to difficulty in canulating a deeply seated vein and so had to be abandoned and catheterized through contralateral superior petrosal sinus and treated with liquid embolic material Onyx ® successfully.

          Conclusion

          In cases where conventional access to the cavernous sinus may not be possible due to local variations of anatomy, multidisciplinary surgical approaches via the SOV provide an alternative route to successfully and safely close a CCF. However, unexpected anatomical variations could also be encountered within the SOV for which the surgeon should be prepared.

          Classification and treatment of spontaneous carotid-cavernous sinus fistulas.

          An anatomical-angiographic classification for carotid-cavernous sinus fistulas is introduced and a series of 14 patients with spontaneous carotid-cavernous sinus fistulas is reviewed to illustrate the usefulness of such a classification for patient evaluation and treatment. Fistulas are divided into four types: Type A are direct high-flow shunts between the internal carotid artery and the cavernous sinus; Type B are dural shunts between meningeal branches of the internal carotid artery and the cavernous sinus; Type C are dural shunts between meningeal branches of the external carotid artery and the cavernous sinus; and Type D are dural shunts between meningeal branches of both the internal and external carotid arteries and the cavernous sinus. The anatomy, clinical manifestations, angiographic evaluation, indications for therapy, and therapeutic options for spontaneous carotid-cavernous sinus fistulas are discussed.

            Carotid-cavernous fistulas.

            Carotid-cavernous fistulas (CCFs) are vascular shunts allowing blood to flow from the carotid artery into the cavernous sinus. The characteristic clinical features seen in patients with CCFs are the sequelae of hemodynamic dysfunction within the cavernous sinus. Once routinely treated with open surgical procedures, including carotid ligation or trapping and cavernous sinus exploration, endovascular therapy is now the treatment modality of choice in many cases. The authors provide a review of CCFs, detailing the current classification and clinical management of these lesions. Therapeutic options including conservative management, open surgery, endovascular intervention, and radiosurgical therapy are presented. The complications and treatment results as reported in the contemporary literature are also reviewed.

              Dural carotid cavernous fistula: definitive endovascular management and long-term follow-up.

              To describe the endovascular treatment and clinical outcome in patients with indirect carotid cavernous fistulas (CCFs) over a 15-year period. To our knowledge, this is the largest series in the medical literature. Interventional case series. A retrospective evaluation of 135 consecutive patients who underwent examination and treatment for indirect CCF was performed. Patients received independent evaluations by ophthalmologists, neurologists, or neuro-ophthalmologists before, during, and after endovascular treatment. Patients initially received noninvasive imaging followed by cerebral arteriography for definitive diagnosis and stratification by angiographic risk factors. Endovascular treatment was performed in 133 (98%) patients and clinical follow-up was achieved in 135 (100%) patients on an average of 56 +/- 4.3 months (range: 2 months-14 years). Angiographic follow-up was performed in 72 (54%) patients with ongoing symptoms or a history of fistula with high-risk angiographic features. Arteriographic cure with long-term clinical outcome is summarized by modified Rankin scale (mRS) and Barthel index (BI). At a mean follow-up of 56 months, 121 (90%) patients were clinically cured. At latest clinical follow-up, 131 (97%) patients showed good recovery (mRS, 1-2; BI 90-100), one (1%) had moderate disability (mRS, 3; BI, 50-60), and three (2%) (mRS, 4; BI, 40-50) were severely disabled. Procedure-related permanent morbidity was 2.3%. There was no operative mortality. With the observed favorable outcomes and low rate of procedural morbidity in this patient population with long-term angiographic and clinical follow-up, endovascular therapy should be the primary treatment for patients with indirect (dural) fistulas of the cavernous sinus.
