NEUROSURGERY. Initial Experience of a Novel Sheath Guide for Transbrachial Coil Embolization of Cerebral Aneurysms in the Anterior Cerebral Circulation

Iwata, Tomonori MD; Mori, Takahisa MD, PhD; Tajiri, Hiroyuki MD; Miyazaki, Yuichi MD; Nakazaki, Masahito MD; Mizokami, Koji MD

BACKGROUND: The transfemoral approach is a common technique for coil embolization of cerebral aneurysms in the anterior cerebral circulation. However, it is difficult to advance a guiding catheter into the carotid artery via the femoral route in patients with a tortuous aortic arch, an unfavorable supra-aortic takeoff, aortic diseases, or occlusion of the femoral artery.

NEUROSURGERY. Flat-Panel Fluoroscopy O-arm–Guided Percutaneous Radiofrequency Cordotomy: A New Technique for the Treatment of Unilateral Cancer Pain

Collins, Kelly L. MD; Patil, Parag G. MD, PhD

BACKGROUND: Percutaneous radiofrequency cordotomy (PRFC) involves controlled ablation of the anterolateral quadrant of the spinal cord, thereby relieving pain. Evolving from a morbid open surgery, the procedure has been modernized through the application of physiological target confirmation, well-regulated thermal ablation, and improved intraoperative imaging.

NEUROSURGERY. Magnetic Resonance Imaging Assessment of Cerebral Arteriovenous Malformation Obliteration After Stereotactic Radiosurgery

BACKGROUND: Stereotactic radiosurgery is ideal for treating small cerebral arteriovenous malformations (AVMs) that are surgically inaccessible. However, given the inherent delay of AVM obliteration and the potential for radiosurgical failure, detailed evaluation of the neurovascular architecture is necessary to monitor persistence of residual flow. Modern imaging systems such as magnetic resonance imaging (MRI) and angiography allow clinicians to assess transnidus flow after radiosurgical intervention.

NEUROSURGERY. Anatomic Risk Factors for Middle Cerebral Artery Aneurysm Rupture: Computed Tomography Angiography Study of 1009 Consecutive Patients

Elsharkawy, Ahmed MD*,‡; Lehečka, Martin MD, PhD*; Niemelä, Mika MD, PhD*; Kivelev, Juri MD, PhD*; Billon-Grand, Romain MD*,§; Lehto, Hanna MD*; Kivisaari, Riku MD, PhD*; Hernesniemi, Juha MD, PhD*

BACKGROUND: The middle cerebral artery (MCA) is the most frequent location for unruptured intracranial aneurysms. Controversy remains as to which unruptured MCA aneurysms should be treated prophylactically.

NEUROSURGERY. Neuroform Intracranial Stenting for Aneurysms Using Simple and Multi-stent Technique Is Associated With Low Risk of Magnetic Resonance Diffusion-Weighted Imaging Lesions

Heller, Robert S. MD; Dandamudi, Venkata MD; Calnan, Daniel PhD; Malek, Adel M. MD, PhD

BACKGROUND: Detection of procedural thromboembolism by diffusion-weighted magnetic resonance imaging (MR-DWI+) can help identify and mitigate endovascular risk factors. Data remain scant on procedural MR-DWI+ following the use of the Neuroform open-cell design stent in aneurysm embolization.

NEUROSURGERY. Early vs Delayed Cerebral Infarction After Aneurysm Repair After Subarachnoid Hemorrhage

Kumar, Abhay MD†; Brown, Robert MD†; Dhar, Rajat MD†; Sampson, Tomoko MD†; Derdeyn, Colin P. MD‡; Moran, Christopher J. MD‡; Diringer, Michael N. MD†,§

BACKGROUND: Cerebral infarction is a major contributor to poor outcome after subarachnoid hemorrhage (SAH). Although usually considered a complication of delayed cerebral ischemia, infarcts may also occur early, in relation to initial brain injury or aneurysm-securing procedures.

NEUROSURGERY. Perioperative Complications After Carotid Artery Stenting: A Contemporary Experience From the University at Buffalo Neuroendovascular Surgery Team

Dumont, Travis M. MD*,‡; Wach, Michael M. BS‡; Mokin, Maxim MD, PhD*,‡; Sorkin, Grant C. MD*,‡; Snyder, Kenneth V. MD, PhD*,‡,§,‖; Hopkins, L. Nelson MD*,‡,§,‖,¶; Levy, Elad I. MD*,‡,§; Siddiqui, Adnan H. MD, PhD*,‡,§

BACKGROUND: Technological advances have resulted in diminishing perioperative complications reported during carotid artery stenting (CAS) trials. Because trial experience lags behind technological advances, an understanding of the incidence of perioperative complications after CAS remains in flux.

NEUROSURGERY. Endovascular Treatment of Complex Aneurysms at the Vertebrobasilar Junction With Flow-Diverting Stents: Initial Experience

Meckel, Stephan MD*; McAuliffe, William MD‡; Fiorella, David MD§; Taschner, Christian A. MD*; Phatouros, Constantine MD‡; Phillips, Timothy John MD‡; Vasak, Paul¶; Schumacher, Martin MD*; Klisch, Joachim MD¶

BACKGROUND: Large or giant complex vertebrobasilar junction aneurysms have a dismal natural history and are often challenging to treat with standard endovascular or neurosurgical techniques.

NEUROSURGERY. A Multicenter Study of Stent-Assisted Coiling of Cerebral Aneurysms With a Y Configuration

Fargen, Kyle M. MD, MPH*; Mocco, J MD, MS‡; Neal, Dan MS*; Dewan, Michael C. MD‡; Reavey-Cantwell, John MD, MS§; Woo, Henry H. MD¶; Fiorella, David J. MD¶; Mokin, Maxim MD, PhD‖; Siddiqui, Adnan H. MD, PhD||; Turk, Aquilla S. DO#; Turner, Raymond D. MD#; Chaudry, Imran MD#; Kalani, M. Yashar S. MD, PhD**; Albuquerque, Felipe MD**; Hoh, Brian L. MD*

BACKGROUND: Stent-assisted coiling with 2 stents in a Y configuration is a technique for coiling complex wide-neck bifurcation aneurysms.

NEUROSURGERY. Volumetric Analysis of Intracranial Arteriovenous Malformations Contoured for CyberKnife Radiosurgery With 3-Dimensional Rotational Angiography vs Computed Tomography/Magnetic Resonance Imaging

Veeravagu, Anand MD†; Hansasuta, Ake MD§; Jiang, Bowen MD†; Karim, Aftab S. MD†; Gibbs, Iris C. MD‡; Chang, Steven D. MD†

BACKGROUND: Accurate target delineation has significant impact on brain arteriovenous malformation (AVM) obliteration, treatment success, and potential complications of stereotactic radiosurgery.

NEUROSURGERY. Diagnostic Yield of Cerebral Angiography in Patients With Computed Tomography-Negative, Lumbar Puncture-Positive Subarachnoid Hemorrhage

Chalouhi, Nohra MD; Witte, Samantha BA; Penn, David L. MS; Soni, Pranay BS; Starke, Robert M. MD; Jabbour, Pascal MD; Gonzalez, L. Fernando MD; Dumont, Aaron S. MD; Rosenwasser, Robert MD; Tjoumakaris, Stavropoula MD

BACKGROUND: Cerebral angiography is generally recommended in patients with subarachnoid hemorrhage (SAH) by positive lumbar puncture (LP) but negative findings on computed tomography (CT). Existing data on the yield of angiography in these patients are very limited.

THE LANCET NEUROLOGY. Effect of intermittent pneumatic compression on disability, living circumstances, quality of life, and hospital costs after stroke: secondary analyses from CLOTS 3, a randomised trial

CLOTS (Clots in Legs Or sTockings after Stroke) Trials Collaboration†

Background: The results of the CLOTS 3 trial showed that intermittent pneumatic compression (IPC) reduced the risk of deep vein thrombosis and improved survival in immobile patients with stroke. IPC is now being widely used in stroke units. Here we describe the disability, living circumstances, quality of life, and hospital costs of patients in CLOTS 3.
