Endovascular embolization of dural arteriovenous fistula may not be a feasible approach depending on the location and/or surrounding structures. ⋯ Combined techniques are required for the management of complex dural arteriovenous fistula. We report a treatment method that can be used for lesions that cannot be treated by endovascular embolization alone along with some technical pitfalls.

More recent studies have focused on clinical outcomes of operative versus nonoperative treatment in patients with adult spinal deformity (ASD). However, scientific support for ASD surgery is weak. We compared outcomes of operative and nonoperative treatment of ASD with minimum 2-year follow-up in a meta-analysis. ⋯ Our meta-analysis showed that operative treatment has been demonstrated to significantly reduce disability and pain and to improve clinical outcomes compared with nonoperative treatment. Further large, multicenter, well-designed studies are necessary to substantiate our results.

Review Case Reports
Endovascular Retrieval of Migrated Coil within the Distal Middle Cerebral Artery Using Stentriever Device.
Displacement of endovascular coils during endovascular embolization of an intracranial aneurysm is a potentially life-threatening complication. Several methods for coil retrieval have been described, including the use of microsnares and microforceps retrieval devices. With the recent surge of stentriever implementation in the treatment of ischemic stroke, some operators are now using such devices in the retrieval of migrated coils. We present a case of a balloon-assisted coil embolization of a communicating segment internal carotid artery aneurysm, complicated by coil migration far distally into the middle cerebral artery, which was retrieved successfully with a stentriever. To the best of our knowledge, this is the furthest migration of a coil to be successfully retrieved with a stentriever. We review conservative and invasive management of displaced coils and the technical advantages of stentrievers over retrieval devices. ⋯ In certain situations, a stentriever does not mandate complete ensnaring of the target to be retrieved and thus need not always be deployed distal to a migrated coil mass to be successful. Due to the mechanical advantage of strut-engagement, stentrievers can afford to be positioned in relatively suboptimal positions, and this is especially useful in cases involving tortuous and small distal vessels (<2 mm diameter).

Review Meta Analysis
Vessel Wall Imaging of Intracranial Aneurysms: Systematic Review and Meta-analysis.
Vessel wall imaging (VWI) is emerging as a novel imaging tool for the management and risk stratification of patients with intracranial saccular aneurysms. Our objective was to compare the rates of wall enhancement in unstable (ruptured, growing, or symptomatic) and stable aneurysms and assess the ability of VWI with high-resolution magnetic resonance imaging to distinguish between these 2 entities. This study was performed according to Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, and eligible studies were identified through a comprehensive literature review. ⋯ There is a statistically significant association between vessel wall enhancement and aneurysm instability. Importantly, the lack of wall enhancement is a strong predictor of aneurysm stability. VWI could potentially provide new insights in the management of intracranial aneurysms.
