AMERICAN JOURNAL OF NEURORADIOLOGY. Thrombus Attenuation Does Not Predict Angiographic Results of Mechanical Thrombectomy with Stent Retrievers

U. Yilmaz, C. Roth, W. Reith and P. Papanagiotou

BACKGROUND AND PURPOSE: Mechanical thrombectomy with stent retrievers in acute stroke has emerged as a promising new technique, with the highest recanalization rate of the therapeutic procedures available thus far. However, in up to 20% of the cases, mechanical thrombectomy with stent retrievers results in poor angiographic outcomes, with Thrombolysis in Cerebral Infarction scores ≤2a. The purpose of this study was to investigate whether thrombus attenuation on the initial CT scan can predict the angiographic outcome of the recanalization procedure in MCA occlusions.

AMERICAN JOURNAL OF NEURORADIOLOGY. Stent-Assisted Coiling in Endovascular Treatment of 500 Consecutive Cerebral Aneurysms with Long-Term Follow-Up

S. Geyik, K. Yavuz, N. Yurttutan, I. Saatci and H.S. Cekirge

BACKGROUND AND PURPOSE: Stent-assisted coil embolization has become one of the most preferred techniques in the treatment of wide-neck intracranial aneurysms; however, long-term patency and safety of the self-expanding neurostents and their role in durability of the endovascular treatment has remained ambiguous. We sought to retrospectively examine the long-term results of self-expanding stent usage in conjunction with coil embolization in treatment of wide-neck cerebral aneurysms.

AMERICAN JOURNAL OF NEURORADIOLOGY. WEB Intrasaccular Flow Disruptor—Prospective, Multicenter Experience in 83 Patients with 85 Aneurysms

C. Papagiannaki, L. Spelle, A.-C. Januel, A. Benaissa, J.-Y. Gauvrit, V. Costalat, H. Desal, F. Turjman, S. Velasco, X. Barreau, P. Courtheoux, C. Cognard, D. Herbreteau, J. Moret and L. Pierot

BACKGROUND AND PURPOSE: The safety and efficacy of WEB flow disruption have been analyzed in small, retrospective series. The object of this study was to evaluate the safety and efficacy of WEB flow disruption in a large, multicenter, prospectively collected population.

AMERICAN JOURNAL OF NEURORADIOLOGY. Contrast-Enhanced Time-Resolved MRA for Follow-Up of Intracranial Aneurysms Treated with the Pipeline Embolization Device

S.R. Boddu, F.C. Tong, S. Dehkharghani, J.E. Dion and A.M. Saindane

BACKGROUND AND PURPOSE: Endovascular reconstruction and flow diversion by using the Pipeline Embolization Device is an effective treatment for complex cerebral aneurysms. Accurate noninvasive alternatives to DSA for follow-up after Pipeline Embolization Device treatment are desirable. This study evaluated the accuracy of contrast-enhanced time-resolved MRA for this purpose, hypothesizing that contrast-enhanced time-resolved MRA will be comparable with DSA and superior to 3D-TOF MRA.

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. Endovascular Treatment of Ophthalmic Artery Aneurysms: Assessing Balloon Test Occlusion and Preservation of Vision in Coil Embolization

J.H. Ahn, Y.D. Cho, H.-S. Kang, J.E. Kim, W.-S. Cho, S.C. Jung, C.H. Kim and M.H. Han

BACKGROUND AND PURPOSE: ICA–ophthalmic artery aneurysms have unique configurations corresponding to relative risks of ophthalmologic morbidities. Presented herein are clinical and radiologic outcomes of coil embolization in ophthalmic artery 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.
