We describe our preliminary experience on the feasibility of using the Willis covered stent in patients with carotid-cavernous fistulas (CCFs). Eleven consecutive patients with post-traumatic CCFs referred for treatment with Willis covered stents were enrolled into this prospective study, and were subsequently followed-up at our hospital. Data on technical success, initial and final angiographic results, mortality, morbidity and final clinical outcome, was collected, with follow-up performed at one, three, six and 12 months, and yearly thereafter. Deployment of the covered stents was technically successful in all patients. Angiographic results following stent placement showed a complete occlusion in eight patients with ten CCFs, and an incomplete occlusion in three. No adverse events occurred either during or after the procedure. Angiographic follow-up (mean 14.73 ± 6.77 months) revealed complete occlusion and no obvious in-stent stenosis in all patients. Clinical follow-up (mean 17.73 ± 6.48 months) demonstrated full recovery in ten patients, and improvement in one. These preliminary results indicate that the use of the Willis covered stent is a feasible procedure, and that it may therefore serve as an alternative treatment for CCFs. Longer follow-up assessments and an expanded clinical trial are needed.
