Iatrogenic Dural Arteriovenous Fistula after Superficial Temporal Artery to Middle Cerebral Artery Anastomosis: A Case Report.

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.

Clinical and Angiographic Outcomes of Wide-necked Aneurysms Treated with the Solitaire AB Stent.

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.

Efficacy of the Disappearance of Lateral Spread Response before and after Microvascular Decompression for Predicting the Long-Term Results of Hemifacial Spasm Over Two Years.

Objective: The purpose of this large prospective study is to assess the association between the disappearance of the lateral spread response (LSR) before and after microvascular decompression (MVD) and clinical long term results over two years following hemifacial spasm (HFS) treatment.

Methods: Continuous intra-operative monitoring during MVD was performed in 244 consecutive patients with HFS. Patients with persistent LSR after decompression (n=22, 9.
