Background and Purpose—Carotid artery stenting (CAS) is an alternative to carotid endarterectomy (CEA) for stroke prevention. The value of this therapy relative to CEA remains uncertain.

Introduction: The possibility of recanalization and the need for retreatment are the most important limitations of intracranial aneurysm embolization. The purpose of the study was to compare the size of aneurysm remnants measured at follow-up with three-dimensional digital subtracted angiography (3D-DSA) and magnetic resonance angiography (MRA).

BACKGROUND AND PURPOSE: The natural history of cerebral aneurysms is thought to be governed by multifactorial processes involving hemodynamics, biomechanics, mechanobiology, and perianeurysmal environment. The purpose of this study was to highlight the importance of considering the influence of contacts with perianeurysmal environment structures on the hemodynamics and geometric evolution of intracranial aneurysms.

Object: The development of multimodality approaches for the treatment of cerebral arteriovenous malformations (AVMs), including microsurgery, endovascular therapy, and radiosurgery, has shifted modern treatment paradigms in the last 10 years. This study examines these changes in detail from a nationwide perspective. Neurosurgical Focus. Jul 2012 / Vol. 33 / No. 1 / Page E11.
Introduction: At present, the risk of future hemorrhage or ischemic insult from vertebral artery (VA) dissection cannot be estimated from available imaging data. We investigated the relationship between symptoms and the angiographic patterns of the dissecting site on balloon test occlusion (BTO) to develop guidelines for clinical decision-making.

The authors present the case of a patient who presented acutely with aneurysmal subarachnoid hemorrhage (SAH) and a contralateral iatrogenic dural arteriovenous fistula (DAVF). Diagnostic angiography was performed, revealing a right-sided middle cerebral artery (MCA) aneurysm and a left-sided DAVF immediately adjacent to the entry of the ventriculostomy and bur hole site. A craniotomy was performed for clipping of the ruptured MCA aneurysm, and the patient subsequently underwent endovascular obliteration of the DAVF 3 days later. The authors present their treatment of an iatrogenic DAVF in a patient with an aneurysmal SAH, considerations in management options, and a literature review on the development of iatrogenic DAVFs.

The therapy of acute stroke has advanced dramatically over the last 15 years with the use of intravenous tPA and intra-arterial catheter-based revascularization techniques. At their best, these therapies allow the physician to arrest the progression of what would otherwise become a devastating stroke. Yet, the majority of patients with stroke still do not benefit from these therapies either because the brief time window of benefit and safety imposes administrative, medical, and logistical demands that have not been met or because, even when applied early, these therapies are effective in only some patients. Therefore, it is important that we expand access to and implement currently available therapies as efficiently as possible. In addition, we must continue to refine these therapies and to develop new ones. This review provides a focused update on the current therapy of acute stroke.

Object: The association of aneurysms and cerebral arteriovenous malformations is well established in the literature. Aside from a small number of case reports and small patient series, this association has not been well explored with cerebral dural arteriovenous fistulas (DAVFs). This study was designed to elucidate this relationship in the authors own patient cohort with DAVFs. Neurosurgical Focus. May 2012 / Vol. 32 / No. 5 / Page E2. DOI: 10.3171/2011.12.FOCUS11336.
BACKGROUND: Untreated patients with symptomatic neonatal presentation of vein of Galen aneurismal malformations (VGAMs) carry almost 100% morbidity and mortality. Medical management and endovascular techniques for neonatal treatment have significantly evolved. OBJECTIVE: To evaluate the clinical and angiographic outcomes of modern management of neonates with refractory heart failure from VGAMs. Neurosurgery: May 2012 - Volume 70 - Issue 5 - p 1207–1214 doi: 10.1227/NEU.0b013e3182417be3.

Carotid-cavernous fistulas (CCFs) are vascular shunts allowing blood to flow from the carotid artery into the cavernous sinus. The characteristic clinical features seen in patients with CCFs are the sequelae of hemodynamic dysfunction within the cavernous sinus. Once routinely treated with open surgical procedures, including carotid ligation or trapping and cavernous sinus exploration, endovascular therapy is now the treatment modality of choice in many cases. The authors provide a review of CCFs, detailing the current classification and clinical management of these lesions. Therapeutic options including conservative management, open surgery, endovascular intervention, and radiosurgical therapy are presented. The complications and treatment results as reported in the contemporary literature are also reviewed. Neurosurgical Focus. May 2012 / Vol. 32 / No. 5 / Page E9. DOI: 10.3171/2012.2.FOCUS1223.
Case Presentation: A 74-year-old woman presents to the emergency department with bruising. She takes warfarin for atrial fibrillation. She has recently begun taking trimethoprim/sulfamethoxazole. Her international normalized ratio (INR) is reported as 8.6. Circulation. 2012; 125: 2944-2947 doi: 10.1161/CIRCULATIONAHA.111.081489. Copyright © 2012 American Heart Association, Inc.
