AMERICAN JOURNAL OF NEURORADIOLOGY. Modifying Flow in the ICA Bifurcation: Pipeline Deployment from the Supraclinoid ICA Extending into the M1 Segment—Clinical and Anatomic Results

E. Nossek, D.J. Chalif, S. Chakraborty and A. Setton

BACKGROUND AND PURPOSE: Utility of the Pipeline Embolization Device extending to the M1 and its clinical and flow consequences at the ICA bifurcation have not been characterized. We analyzed flow modification in cases where a single Pipeline Embolization Device was deployed from the M1 to the distal supraclinoid ICA, covering the A1, for aneurysm treatment.

AMERICAN JOURNAL OF NEURORADIOLOGY. Morphologic and Hemodynamic Risk Factors in Ruptured Aneurysms Imaged before and after Rupture

A. Chien and J. Sayre

BACKGROUND AND PURPOSE: Due to limited information about aneurysm natural history, choosing the appropriate management strategy for an unruptured aneurysm is challenging. By comparing unruptured and ruptured cases, studies have identified a variety of aneurysm morphologic and hemodynamic properties as risk factors for rupture. In this study, we investigated changes in 4 ruptured aneurysms before and after rupture and tested whether previously published risk factors identified a risk before rupture.

AMERICAN JOURNAL OF NEURORADIOLOGY. Risk Factors for Early Hemorrhagic Complications after Endovascular Coiling of Ruptured Intracranial Aneurysms

T. Ohta, K. Murao, K. Miyake, K. Takemoto and K. Nakazawa

BACKGROUND AND PURPOSE: The risk factors of early hemorrhagic complications after endovascular coiling are not well-known. We identified the factors affecting early hemorrhagic complications, defined as any expansion or appearance of hemorrhage shown by head CT in the initial 48 hours after coiling.

AMERICAN JOURNAL OF NEURORADIOLOGY. Vision Outcomes and Major Complications after Endovascular Coil Embolization of Ophthalmic Segment Aneurysms

C.R. Durst, R.M. Starke, J. Gaughen, Q. Nguyen, J. Patrie, M.E. Jensen and A.J. Evans

BACKGROUND AND PURPOSE: As aneurysms arising from the ophthalmic segment of the internal carotid artery increase in size, they can compress the optic nerve, prompting patients to present with visual disturbances. The purpose of this article is to describe the clinical and angiographic results with an emphasis on visual outcomes following the endovascular treatment of ophthalmic segment ICA aneurysms.

AMERICAN JOURNAL OF NEURORADIOLOGY. “Y” and “X” Stent-Assisted Coiling of Complex and Wide-Neck Intracranial Bifurcation Aneurysms

B. Bartolini, R. Blanc, S. Pistocchi, H. Redjem and M. Piotin

BACKGROUND AND PURPOSE: Stent-assisted coiling with two stents has been described in some series for the treatment of complex and wide-neck bifurcation aneurysms. Our aim was to report our experience of a stent-assisted coiling technique with double stents in “Y” and “X” configurations, with emphasis on safety, feasibility, and efficacy.

AMERICAN JOURNAL OF NEURORADIOLOGY. Evaluation of a Metal Artifacts Reduction Algorithm Applied to Postinterventional Flat Panel Detector CT Imaging

D.A. Stidd, H. Theessen, Y. Deng, Y. Li, B. Scholz, C. Rohkohl, M.D. Jhaveri, R. Moftakhar, M. Chen and D.K. Lopes

BACKGROUND AND PURPOSE: Flat panel detector CT images are degraded by streak artifacts caused by radiodense implanted materials such as coils or clips. A new metal artifacts reduction prototype algorithm has been used to minimize these artifacts. The application of this new metal artifacts reduction algorithm was evaluated for flat panel detector CT imaging performed in a routine clinical setting.

AMERICAN JOURNAL OF NEURORADIOLOGY. Treatment of Supratentorial Spontaneous Intracerebral Hemorrhage Using Image-Guided Minimally Invasive Surgery: Initial Experiences of a Flat Detector CT–Based Puncture Planning and Navigation System in the Angiographic Suite

Z. Yang, B. Hong, Z. Jia, J. Chen, J. Ge, J. Han, J. Beilner, Y. Zhang, Y. Fang and J. Liu

BACKGROUND AND PURPOSE: The intracerebral hemorrhage drainage through minimally invasive approach is emerging as an alternative for traditional craniotomy, due to its improved survival rate and reduced complication rate. In this study, we investigated the feasibility and safety of a flat detector CT–based puncture planning and navigation system for minimally invasive hematoma drainage on patients with intracerebral hemorrhage.

AMERICAN JOURNAL OF NEURORADIOLOGY. Leukoaraiosis Predicts a Poor 90-Day Outcome after Endovascular Stroke Therapy

J. Zhang, A.S. Puri, M.A. Khan, R.P. Goddeau Jr and N. Henninger

BACKGROUND AND PURPOSE: Leukoaraiosis is a common finding among patients with ischemic stroke and has been associated with poor stroke outcomes. Our aim was to ascertain whether the severity of pre-existing leukoaraiosis is associated with outcome in patients with acute ischemic stroke who are treated with endovascular stroke therapy.

AMERICAN JOURNAL OF NEURORADIOLOGY. Mechanical Embolectomy for Acute Ischemic Stroke in the Anterior Cerebral Circulation: The Gothenburg Experience during 2000–2011

A. Rentzos, C. Lundqvist, J.-E. Karlsson, V. Vilmarsson, K. Schnabel and G. Wikholm

BACKGROUND AND PURPOSE: Intra-arterial treatment of proximal occlusions in the cerebral circulation have become an important tool in the management of acute ischemic stroke. Our goal was to evaluate the safety and efficacy of intra-arterial acute ischemic stroke treatment performed in our institution in consecutive patients with anterior circulation occlusion during 2000–2011.

AMERICAN JOURNAL OF NEURORADIOLOGY. Endovascular Treatment of Internal Carotid Artery Bifurcation Aneurysms: A Single-Center Experience and a Systematic Review and Meta-Analysis

S.F. Morales-Valero, W. Brinjikji, M.H. Murad, J.T. Wald and G. Lanzino

BACKGROUND AND PURPOSE: Endovascular coiling of internal carotid artery bifurcation aneurysms can be challenging due to unfavorable morphologic features. With improvements in endovascular techniques, several series have detailed the results and complications of endovascular treatment of aneurysms at this location. We performed a systematic review and meta-analysis of published series on the endovascular treatment of ICA bifurcation aneurysms, including a tertiary referral center experience.

AMERICAN JOURNAL OF NEURORADIOLOGY. A Single Pipeline Embolization Device is Sufficient for Treatment of Intracranial Aneurysms

N. Chalouhi, S. Tjoumakaris, J.L.H. Phillips, R.M. Starke, D. Hasan, C. Wu, M. Zanaty, D. Kung, L.F. Gonzalez, R. Rosenwasser and P. Jabbour

BACKGROUND AND PURPOSE: The Pipeline Embolization Device has emerged as an important treatment option for intracranial aneurysms. The number of devices needed to treat an aneurysm is uncertain and is the subject of vigorous debate. The purpose of this study was to compare rates of complications, aneurysm occlusion, and outcome in patients treated with a single-versus-multiple Pipeline Embolization Devices.

AMERICAN JOURNAL OF NEURORADIOLOGY. Building Multidevice Pipeline Constructs of Favorable Metal Coverage: A Practical Guide

M. Shapiro, E. Raz, T. Becske and P.K. Nelson

BACKGROUND AND PURPOSE: The advent of low-porosity endoluminal devices, also known as flow diverters, exemplified by the Pipeline in the United States, produced the greatest paradigm shift in cerebral aneurysm treatment since the introduction of detachable coils. Despite robust evidence of efficacy and safety, key questions regarding the manner of their use remain unanswered. Recent studies demonstrated that the Pipeline device geometry can dramatically affect its metal coverage, emphasizing the negative effects of oversizing the device relative to its target vessels. This follow-up investigation focuses on the geometry and coverage of multidevice constructs.
