JOURNAL OF VASCULAR SURGERY. Assessing the impact of distal protection filter design characteristics on 30-day outcomes of carotid artery stenting procedures

Natasha A. Loghmanpour, MS, Gail M. Siewiorek, PhD, Kelly M. Wanamaker, MD, Satish C. Muluk, MD, Rabih Chaer, MD, Mark H. Wholey, MD, Ender A. Finol, PhD

Objective: This study aims to review retrospectively the records of patients treated with carotid artery stenting (CAS) to investigate the potential correlations between clinical variables, distal protection filter (DPF) type and characteristics, and 30-day peri-/postprocedural outcomes.

STROKE. High-Risk Plaque for Carotid Artery Stenting Evaluated With 3-Dimensional T1-Weighted Gradient Echo Sequence

Hiroshi Tanemura, MD; Masayuki Maeda, MD, PhD; Naoki Ichikawa, MD; Yoichi Miura, MD; Yasuyuki Umeda, MD, PhD; Seiji Hatazaki, MD, PhD; Naoki Toma, MD, PhD; Fumio Asakura, MD, PhD; Hidenori Suzuki, MD, PhD; Hiroshi Sakaida, MD, PhD; Satoshi Matsushima, MD, PhD; Waro Taki, MD, PhD

Background and Purpose—Preventing cerebral embolisms is a major concern with carotid artery stenting (CAS). This study evaluated 3-dimensional T1-weighted gradient echo (3D T1GRE) sequence to predict cerebral embolism related to CAS.

AMERICAN JOURNAL OF NEURORADIOLOGY. Efficacy and Safety of Flow Diversion for Paraclinoid Aneurysms: A Matched-Pair Analysis Compared with Standard Endovascular Approaches

G. Lanzino, E. Crobeddu, H.J. Cloft, R. Hanel and D.F. Kallmes

BACKGROUND AND PURPOSE: Flow diversion is a new strategy for the treatment of complex paraclinoid aneurysms. However, flow diverters have, to date, not been tested in direct comparison with other available treatments. We present a matched-pair comparison of paraclinoid aneurysms treated with the PED versus other endovascular techniques.

NEURORADIOLOGY. Stents and flow diverters in the treatment of aneurysms: device deformation in vivo may alter porosity and impact efficacy

Fabrice Bing, Tim E. Darsaut, Igor Salazkin, Alina Makoyeva, Guylaine Gevry, Jean Raymond

Introduction: High-porosity (HP) and flow-diverting (FD) stents are increasingly used to treat intracranial aneurysms. In vivo device deformations and their impact on the porosity of the segment of device lying over the aneurysm neck remain inadequately characterized.

AMERICAN JOURNAL OF NEURORADIOLOGY. Effect of Cilostazol in Preventing Restenosis after Carotid Artery Stenting Using the Carotid Wallstent: A Multicenter Retrospective Study

K. Takayama, T. Taoka, H. Nakagawa, K. Myouchin, T. Wada, M. Sakamoto, K. Furuichi, S. Iwasaki, S. Kurokawa and K. Kichikawa

BACKGROUND AND PURPOSE: Restenosis after CAS is a postoperative problem, with a reported frequency of approximately 2%–8%. However differences in stent design, procedure, and the antiplatelet agent appear to affect the incidence of restenosis. We assessed the frequency of restenosis and the effect of the antiplatelet agent CLZ in preventing restenosis after CAS by the standard procedure using the CWS.

STROKE. Is Intra-Arterial Thrombolysis Beneficial for M2 Occlusions? Subgroup Analysis of the PROACT-II Trial

Ralph Rahme, MD; Todd A. Abruzzo, MD; Renee’ Hebert Martin, PhD; Thomas A. Tomsick, MD; Andrew J. Ringer, MD; Anthony J. Furlan, MD; Janice A. Carrozzella, RN; Pooja Khatri, MD, MSc

Background and Purpose—The role of endovascular therapy for acute M2 trunk occlusions is debatable. Through a subgroup analysis of Prolyse in Acute Cerebral Thromboembolism-II, we compared outcomes of M2 occlusions in treatment and control arms.

STROKE. A Randomized Controlled Trial of Prophylactic Intra-aortic Balloon Counterpulsation in High-Risk Aneurysmal Subarachnoid Hemorrhage

Diederik Olivier Bulters, FRCS(SN); Anthony A. Birch, PhD; Edward Hickey, FRCS(C); Ian Tatlow; Karen Sumner, BNS(Hons); Robert Lamb, FRCS; Dorothy Lang, FRCS

Background and Purpose—To assess whether prophylactic postoperative intraaortic balloon counterpulsation (IABC) reduces the risk of poor outcome because of vasospasm following aneurysmal subarachnoid haemorrhage relative to conventional hypervolemic therapy (HT).

NEURORADIOLOGY. Is general anaesthesia preferable to conscious sedation in the treatment of acute ischaemic stroke with intra-arterial mechanical thrombectomy? A review of the literature

N. John, P. Mitchell, R. Dowling, B. Yan

Introduction: Intra-arterial mechanical thrombectomy (IAMT) is an endovascular technique that allows for the acute retrieval of intravascular thrombi and is increasingly being used for the treatment of acute ischaemic stroke (AIS). There are currently two anaesthetic options during IAMT: general anaesthesia (GA) and conscious sedation (CS). The decision to use GA versus CS is the source of controversy, as it requires careful balance between patient pain, movement and airway protection whilst minimising time delay and haemodynamic fluctuations. This review examines and summarises the evidence for the use of GA versus CS in the treatment of AIS by IAMT.

NEUROSURGERY. Transfemoral Transarterial Onyx Embolization of Carotid Body Paragangliomas: Technical Considerations, Results, and Strategies for Complication Avoidance

Kalani, M. Yashar S. MD, PhD; Ducruet, Andrew F. MD; Crowley, R. Webster MD; Spetzler, Robert F. MD; McDougall, Cameron G. MD; Albuquerque, Felipe C. MD

BACKGROUND: The association of carotid body paragangliomas with neurovascular structures can cause cranial nerve injury and significant intraoperative blood loss. Preoperative embolization may be performed either percutaneously or transarterially.

NEUROSURGERY. Double Arterial Catheterization Technique for Embolization of Brain Arteriovenous Malformations With Onyx

Renieri, Leonardo MD; Consoli, Arturo MD; Scarpini, Giulia MD; Grazzini, Giulia MD; Nappini, Sergio MD; Mangiafico, Salvatore MD

BACKGROUND: Arteriovenous malformation (AVM) treatment is multidisciplinary, and the patient may undergo embolization, neurosurgery, or radiosurgery combined. Great improvement in endovascular techniques was provided by the introduction of Onyx with different kinds of approach.

NEUROSURGERY. Transvenous Coil Embolization of an Intraorbital Arteriovenous Fistula: Case Report and Review of the Literature

Williamson, Richard W. MD; Ducruet, Andrew F. MD; Crowley, R. Webster MD; McDougall, Cameron G. MD; Albuquerque, Felipe C. MD

BACKGROUND AND IMPORTANCE: Purely intraorbital arteriovenous fistulas (AVFs), which are rare vascular malformations that clinically mimic carotid-cavernous fistulas (CCFs), involve a fistula from the ophthalmic artery to 1 of the draining ophthalmic veins. We describe a case of an intraorbital AVF treated with transvenous endovascular coil embolization via the inferior petrosal sinus (IPS) route and review the literature on this rare entity.
