STROKE. Clinical Sciences. Early Detection and Quantification of Cerebral Venous Thrombosis by Magnetic Resonance Black-Blood Thrombus Imaging

Qi Yang, MD, PhD*; Jiangang Duan, MD, PhD*; Zhaoyang Fan, MD, PhD*; Xiaofeng Qu, MD, PhD; Yibin Xie, PhD; Christopher Nguyen, PhD; Xiangying Du, MD, PhD; Xiaoming Bi, PhD; Kuncheng Li, MD, PhD; Xunming Ji, MD, PhD; Debiao Li, PhD

Background and Purpose: Early diagnosis of cerebral venous thrombosis (CVT) is currently a major clinical challenge. We proposed a novel magnetic resonance black-blood thrombus imaging technique (MRBTI) for detection and quantification of CVT.

STROKE. Clinical Sciences. Admission Hyperglycemia and Clinical Outcome in Cerebral Venous Thrombosis

Susanna M. Zuurbier, MD*; Sini Hiltunen, MD*; Turgut Tatlisumak, MD, PhD; Guusje M. Peters, BSc; Suzanne M. Silvis, MD; Elena Haapaniemi, MD, PhD; Nyika D. Kruyt, MD, PhD; Jukka Putaala, MD, PhD; Jonathan M. Coutinho, MD, PhD

Background and Purpose: Admission hyperglycemia is associated with poor clinical outcome in ischemic and hemorrhagic stroke. Admission hyperglycemia has not been investigated in patients with cerebral venous thrombosis.

STROKE. Clinical Sciences. Radiosurgery for Cerebral Arteriovenous Malformations in A Randomized Trial of Unruptured Brain Arteriovenous Malformations (ARUBA)-Eligible Patients

Dale Ding, MD; Robert M. Starke, MD, MSc; Hideyuki Kano, MD; David Mathieu, MD; Paul Huang, MD; Douglas Kondziolka, MD; Caleb Feliciano, MD; Rafael Rodriguez-Mercado, MD; Luis Almodovar, MD; Inga S. Grills, MD; Danilo Silva, MD; Mahmoud Abbassy, MD; Symeon Missios, MD; Gene H. Barnett, MD; L. Dade Lunsford, MD; Jason P. Sheehan, MD, PhD

Background and Purpose: The benefit of intervention for patients with unruptured cerebral arteriovenous malformations (AVMs) was challenged by results demonstrating superior clinical outcomes with conservative management from A Randomized Trial of Unruptured Brain AVMs (ARUBA). The aim of this multicenter, retrospective cohort study is to analyze the outcomes of stereotactic radiosurgery for ARUBA-eligible patients.

STROKE. Clinical Sciences. Ankle-Brachial Index and Recurrent Stroke Risk. Meta-Analysis

Ja Bin Hong, BSc*; Christopher O. Leonards, BA*; Matthias Endres, MD; Bob Siegerink, PhD; Thomas G. Liman, MD, MSc

Background and Purpose: The ankle-brachial index (ABI) is a fast, cheap, noninvasive indicator of atherosclerotic burden that may also be a predictor of stroke recurrence. In this systematic review and meta-analysis, we sought to explore ABI’s merit as a marker for stroke recurrence and vascular risk by synthesizing the data currently available in stroke literature.

SPRINGER. CT angiography versus 3D rotational angiography in patients with subarachnoid hemorrhage

R. S. Bechan, S. B. van Rooij, M. E. Sprengers, J. P. Peluso, M. Sluzewski, C. B. Majoie, W. J. van Rooij

Introduction: CT angiography (CTA) is increasingly used as primary diagnostic tool to replace digital subtraction angiography (DSA) in patients with subarachnoid hemorrhage (SAH). However, 3D rotational angiography (3DRA) has substituted DSA as a reference standard. In this prospective observational study, we compare CTA with 3DRA of all cerebral vessels in a large cohort of patients with SAH.

AMERICAN JOURNAL OF NEURORADIOLOGY. Flow-Diverter Stents for the Treatment of Saccular Middle Cerebral Artery Bifurcation Aneurysms

J. Caroff, H. Neki, C. Mihalea, F. D´Argento, H. Abdel Khalek, L. Ikka, J. Moret and L. Spelle

BACKGROUND AND PURPOSE: The flow-diverter stent has been proved a feasible, safe, and efficient technique, particularly for the treatment of large and broad-neck carotid siphon aneurysms. Wide-neck bifurcation aneurysms remain, in some cases, a challenge for neurointerventionalists. We report the outcomes of the treatment of saccular middle cerebral artery bifurcation aneurysms with flow diversion in our institution.

AMERICAN JOURNAL OF NEURORADIOLOGY. The Revascularization Scales Dilemma: Is It Right to Apply the Treatment in Cerebral Ischemia Scale in Posterior Circulation Stroke?

C. Jung, W. Yoon, S.J. Ahn, B.S. Choi, J.H. Kim and S.H. Suh

BACKGROUND AND PURPOSE: Although various revascularization scales are used in the angiographic evaluation of acute ischemic stroke, observer reliability tests of these scales have been rarely performed for posterior circulation stroke. We aimed to evaluate inter- and intraobserver variability of 2 scales, the modified Treatment in Cerebral Ischemia and the Arterial Occlusive Lesion, in posterior circulation stroke.

AMERICAN JOURNAL OF NEURORADIOLOGY. Stent Retriever Thrombectomy in Patients Who Are Ineligible for Intravenous Thrombolysis: A Multicenter Retrospective Observational Study

F. Dorn, S. Prothmann, M. Patzig, H. Lockau, C. Kabbasch, O. Nikoubashman, T. Liebig, C. Zimmer, H. Brückmann, M. Wiesmann, H. Stetefeld, H. Poppert, A. Reich, L. Kellert and G. Fesl

BACKGROUND AND PURPOSE: Intravenous thrombolysis with rtPA is the standard of care for patients with acute ischemic stroke within 4.5 hours after symptom onset. However, a considerable number of patients are ineligible for IV thrombolysis due to various contraindications. Recent studies have proved the superiority of mechanical thrombectomy for patients with large-vessel occlusions in combination with IV rtPA compared with IV rtPA alone. We aimed to demonstrate the efficacy of mechanical thrombectomy for patients who are ineligible for IV rtPA.

AMERICAN JOURNAL OF NEURORADIOLOGY. High-Resolution C-Arm CT and Metal Artifact Reduction Software: A Novel Imaging Modality for Analyzing Aneurysms Treated with Stent-Assisted Coil Embolization

I. Yuki, Y. Kambayashi, A. Ikemura, Y. Abe, I. Kan, A. Mohamed, C. Dahmani, T. Suzuki, T. Ishibashi, H. Takao, M. Urashima and Y. Murayama

BACKGROUND AND PURPOSE: Combination of high-resolution C-arm CT and novel metal artifact reduction software may contribute to the assessment of aneurysms treated with stent-assisted coil embolization. This study aimed to evaluate the efficacy of a novel Metal Artifact Reduction prototype software combined with the currently available high spatial-resolution C-arm CT prototype implementation by using an experimental aneurysm model treated with stent-assisted coil embolization.

AMERICAN JOURNAL OF NEURORADIOLOGY. Cerebral Angiography for Evaluation of Patients with CT Angiogram-Negative Subarachnoid Hemorrhage: An 11-Year Experience

J.J. Heit, G.T. Pastena, R.G. Nogueira, A.J. Yoo, T.M. Leslie-Mazwi, J.A. Hirsch and J.D. Rabinov

BACKGROUND AND PURPOSE: CT angiography is increasingly used to evaluate patients with nontraumatic subarachnoid hemorrhage given its high sensitivity for aneurysms. We investigated the yield of digital subtraction angiography among patients with SAH or intraventricular hemorrhage and a negative CTA.
