RESUMEN

Dural arteriovenous fistulas (AVFs) are uncommon, representing only 10% to 15% of all intracranial AVFs. Here we present the case of a patient with cerebral infarction who experienced a dural AVF after craniotomy for superficial temporal artery (STA) to middle cerebral artery (MCA) bypass surgery. A 48-year-old man presented with dysarthria and right side hemiparesis. A brain magnetic resonance imaging scan revealed multiple acute infarctions and severe stenosis of the left MCA. Therefore, STA-MCA bypass surgery was performed. A follow-up angiography performed 2 weeks after the surgery showed an abnormal vascular channel from the left middle meningeal artery (MMA) to the middle meningeal vein (MMV) just anterior to the border of the craniotomy margin. This fistula originated from a screw used for cranial fixation. The screw injured the MMA and MMV, and this resulted in the formation of a fistula. The fistula was successfully treated with transarterial embolization. Surgeons should be careful when fixing bones with screws and plates as fistulas can develop if vessels are injured.

RESUMEN

OBJECTIVE: This study investigated the clinical and angiographic outcomes of treatment with stent-assisted coil embolization using the Solitaire AB stents for wide-necked intracranial aneurysms. METHODS: From October 2010 to December 2011, 22 patients with aneurysms were treated with the Solitaire AB stent. One patient with a dissecting aneurysm was excluded, thus 21 patients with 21 wide-necked saccular aneurysms were included in this study. The technical success rate, procedure-related complications, initial and follow-up angiographic results, and clinical outcomes were retrospectively collected. RESULTS: The locations of aneurysms were as follows: paraclinoid in 14, distal internal carotid artery in 4, and vertebral artery in 3 patients. All aneurysms were unruptured and less than 10 mm-sized. The mean dome-to-neck ratio of the aneurysms was 1.00 (range: 0.45-1.81). The mean follow-up duration was 12.1 (7-15) months after the initial procedure. The technical success rate was 21 (95.5%) of 22 patients with aneurysms. Fortunately, there were no procedure-related complications. Follow-up angiography showed that the rate of complete occlusion was 57.1%, neck remnants 38.1%, and incomplete occlusion 4.8%. CONCLUSION: We suggest that using Solitaire AB stent is technically feasible and safe in the stent-assisted coil embolization for wide-necked saccular intracranial aneurysms. To evaluate the long-term effects of this stent, further follow-up angiography is needed.
