Clinical Outcome of Patients with Poor-Grade Aneurysmal Subarachnoid Hemorrhage with Bundled Treatments: A Propensity Score-Matched Analysis
Poor-grade aneurysmal subarachnoid hemorrhage (aSAH), defined as Hunt and Hess (HH) grades IV and V, is a challenging disease because of its high mortality and poor functional outcomes. The effectiveness of bu...

Endovascular Treatment of Intracranial Aneurysms Using a Microcatheter Protection
Stent protective or balloon remodeling techniques have enabled coil embolization of complexly configured aneurysms. Still, the utility of such methods may be limited in some small-caliber and/or inherently tor...

Endovascular Treatment of Fenestration-related Aneurysms
Endovascular treatment of fenestration-related aneurysms (FAs) is prone to technical challenges, given the inherent complexities. Herein, we have analyzed FAs in terms of angioarchitectural characteristics and...

Endovascular treatment of medullary bridging vein-draining dural arteriovenous fistulas: foramen magnum vs. craniocervical junction lesions
Dural arteriovenous fistulas (AVFs) draining to medullary bridging vein (MBV) are located at foramen magnum (FM) and craniocervical junction (CCJ). Such fistulas are rare but pose a challenge to endovascular m...

Delayed Progression to Major Recanalization in Coiled Aneurysms with Minor Recanalization at 36-Month Follow-up
The aim was to monitor aneurysms that show imaging evidence of minor recanalization 36 months after coil embolization and to determine the rate and related risk factors of major recanalization during more prol...

Does Systemic Hypertension Impact Recanalization of Coiled Aneurysms?
It is well known that hypertension is a significant factor in the formation, growth, and rupture of aneurysms and recanalization of coiled aneurysms is affected by hemodynamic stress. At present, however, the ...

Neurological Pupil Index as an Indicator of Neurological Worsening in Large Hemispheric Strokes
Cerebral herniation due to brain edema is the major cause of neurological worsening in patients suffering large hemispheric strokes. In this study, we investigated whether quantitative pupillary response could...

Growth of Asymptomatic Intracranial Fusiform Aneurysms
Growth of intracranial fusiform aneurysms (IFA) may become clinically problematic through a mass effect or rupture. We investigated the growth rate and factors contributing to growth in asymptomatic untreated ...

Correction to: Does stent type impact coil embolization outcomes in extended follow-up of small-sized aneurysms (< 10 mm)?
The original version of this article contained a mistake in Fig. 4: Fig. 4a and d were interchanged. The correct figure is shown below. The original article has been corrected.

Does stent type impact coil embolization outcomes in extended follow-up of small-sized aneurysms (< 10 mm)?
Self-expandable stents have enabled endovascular treatment of wide-necked aneurysms (ordinarily viewed as technically prohibitive), with favorable outcomes. However, the impact of stent type on occlusive stabi...

Ruptured Aneurysms of Collateral Vessels in Adult Onset Moyamoya Disease with Hemorrhagic Presentation
Strategies for treating intracranial aneurysms of collateral vessels in adult onset moyamoya disease (MMD) remain unclear, because overall case numbers are limited and data on long-term outcomes are lacking. T...

Growth of Untreated Unruptured Small-sized Aneurysms (≺7mm): Incidence and Related Factors
The need to treat small (<7 mm) unruptured aneurysms is still controversial, despite data collected through several large cohort studies. Such lesions typically are incidental findings, usually followed for po...

Modified coil protection for proper coil frame configuration in wide-necked aneurysms
Although various protective techniques for treating wide-necked intracranial aneurysms currently exist and continue to evolve, their utility may be limited in some lesions with complex configurations, small-ca...

Article
Progressive thrombosis of small saccular aneurysms filled with contrast immediately after coil embolization: analysis of related factors and long-term follow-up
Although it is well-known that incomplete occlusion of aneurysms after coil embolization predisposes to later recanalization, not all aneurysms will be fully occluded by coiling. In follow-up, we evaluated out...

Morphology and related hemodynamics of the internal carotid arteries of moyamoya patients
Morphological studies investigating the intracranial-extradural internal carotid artery with moyamoya disease have not been reported. We designed this case–control study to investigate the morphological differ...

Article
Modified protection using far proximal portion of self-expandable closed-cell stents for embolization of wide-necked intracranial aneurysms
Stent-assisted embolization is sometimes limited in wide-necked aneurysms involving the acute-angled origins of tortuous branching arteries, and occasionally, Y-shaped stenting is required to remedy the sweepi...

Mid-term outcome of intracranial aneurysms treated with HydroSoft coils compared to historical controls treated with bare platinum coils: a single-center experience
HydroSoft (MicroVention, Aliso Viejo, CA), a hydrogel-platinum coil hybrid device, is one of various efforts to overcome recanalization of coiled intracranial aneurysms. The purpose of this study was to evalua...
