Intracranial stent placement assists in the coiling of wide-neck aneurysms and aids in reconstructing and protecting the parent artery. In this study, we analyze our experience in the use of the Neuroform system. AJNR Am J Neuroradiol 2011 32: 31-136 originally published online on October 21, 2010, 10.3174/ajnr.A2245.
Hemodynamics are thought to play an important role in the mechanisms of aneurysm pathogenesis, progression, and rupture. The purpose of this study was to define quantitative measures related to qualitative flow characteristics previously analyzed and to investigate their relationship to aneurysm rupture. AJNR Am J Neuroradiol 2011 32: 145-151originally published online on December 2, 2010, 10.3174/ajnr.A2419.
Retrievable stents combine the high recanalization rate of stents and the capability of removing the thrombus offered by mechanical thrombectomy devices. We hypothesized that retrievable stents shorten time to recanalization in the multimodal approach for endovascular stroke treatment.

Flow-diverter stents are an alternative treatment for challenging and recurrent aneurysms. Thrombosis of the sac is thought to induce perianeurysmal brain inflammation, but such phenomena have never been studied in flow-diverter devices. We developed imaging data to explain the clinical exacerbation of symptoms after flow-diversion treatment.

Until now, endovascular treatment of symptomatic atherosclerotic stenosis in small intracranial arteries (< = 2.5 mm) was limited. We evaluated the safety and efficacy of the treatment by using Wingspan stents in arteries of this caliber. AJNR Am J Neuroradiol 2012 33: 343-347originally published online on December 15, 2011, 10.3174/ajnr.A2772.
There are only a few reports on the feasibility and safety of stents used in the PICA, and clinical and angiographic follow-up results have not been fully addressed. We report our experiences of treating PICA origin or vertebral arteryPICA lesions by using self-expanding stents as adjuvant or rescue therapy with angiographic and clinical follow-up results. AJNR Am J Neuroradiol 2012 33: 348-352originally published online on November 3, 2011, 10.3174/ajnr.A2741.
Wide-neck bifurcating aneurysms are increasingly treated with intracranial stent-assisted coiling by using shape-memory alloy microstents. We sought to investigate the short- and long-term effects of intracranial stent implantation on the geometry and angular conformation of the stent-coiled vascular bifurcation. AJNR Am J Neuroradiol 2012 33: 649-654originally published online on December 22, 2011, 10.3174/ajnr.A2841.
The limitations of the medical management of symptomatic intracranial arterial stenosis (SIAS) have encouraged the development of new strategies, such as endovascular treatment. In this study, the authors report and analyze a series of 63 endovascular procedures in which the Wingspan stent system was used. JNS October 2011, Volume 115, Issue 4. J Neurosurg 115:686–693, 2011
The purpose of this ongoing study is to compare the safety and efficacy of microsurgical clipping and endovascular coil embolization for the treatment of acutely ruptured cerebral aneurysms and to determine if one treatment is superior to the other by examining clinical and angiographic outcomes. The authors examined the null hypothesis that no difference exists between the 2 treatment modalities in the setting of subarachnoid hemorrhage (SAH). The current report is limited to the clinical results at 1 year after treatment. JNS January 2012, Volume 116, Issue 1. J Neurosurg 116:135–144, 2012

The use of Onyx in the treatment of intracranial AVMs has increased the cure rate of endovascular embolization compared with the use of liquid adhesive agents. Inadvertent occlusion of the draining veins before the complete exclusion of the nidus constitutes a major risk of bleeding. We report a case series using the technique of double simultaneous arterial catheterization as an approach to achieve the complete exclusion of the nidus before reaching the venous drainage, through a more controlled hemodynamic filling. AJNR Am J Neuroradiol 2011 32: 152-158originally published online on October 21, 2010, 10.3174/ajnr.A2247.
Background and Purpose—The purposes of this study were to track mortality and rehospitalizations over 5 years poststroke in a stroke cohort (SC) and compare long-term risks of complications to a matched nonstroke cohort (NSC).

ISRs remain a major issue in the endovascular management of ICAD, requiring retreatment by reangioplasty. The aim of the present study was to evaluate the technical feasibility, safety, and efficiency of the novel DEBs for neurovascular ISRs.

Introduction Magnetic resonance angiography (MRA) screening for recurrence of a coiled intracranial aneurysm and formation of new aneurysms long-term after coiling may induce anxiety and depression. In coiled patients, we evaluated effects on mood and level of anxiety from longterm follow-up MRA in comparison to general population norms. Neuroradiology (2011) 53:343–348.

Introduction The aim of this study was to introduce and assess a new magnetic resonance (MR) technique for selective peripheral nerve imaging, called “subtraction of unidirectionally encoded images for suppression of heavily isotropic objects” (SUSHI).
