Safety and efficacy of intravenous thrombolysis in stroke patients with recent transient ischemic attack are hotly debated. Patients suffering transient ischemic attack may present with diffusion-weighted imaging lesions, and although normal computed tomography would not preclude thrombolysis, the concern is that they may be at higher risk for hemorrhage postthrombolysis treatment. Prior ipsilateral transient ischemic attack might provide protection due to ischemic preconditioning. We assessed post-thrombolysis outcomes in stroke patients who had prior transient ischemic attack. © 2011 The Authors. International Journal of Stroke.

Small clinical series have reported the safety of intravenous thrombolysis in ischemic stroke related to extracranial internal carotid dissection. However, no studies specifically analyzing the effects on stroke outcome are available. Aims Our goal was to evaluate whether patients with ischemic stroke related to extracranial internal carotid dissection obtain any benefit from intravenous thrombolysis. Copyright © 2011 The Authors.

Acute occlusions of the large intracranial arteries are relatively resistant to intravenous thrombolysis. Therefore, multimodal approaches combining intravenous thrombolysis with endovascular mechanical recanalization are increasingly being applied. In this setting, intravenous thrombolysis may facilitate subsequent mechanical thrombectomy. To test this hypothesis, we analyzed the influence of intravenous thrombolysis on net intervention time in subsequent endovascular mechanical recanalization. Methods In this retrospective single-center analysis,wecompared net intervention time with and without preceding intravenous thrombolysis in patients treated by endovascular mechanical recanalization between 01/2003 and 06/2010. The net intervention timewas defined as the interval between the onset of endovascular thrombus manipulation and successful vessel recanalization.

Cerebral small vessel disease is difficult to directly visualize in vivo. Therefore, we rely on radiological phenotypes as surrogate markers of disease. The principal phenotypes of clinical interest are small, deep brain infarcts, cerebral white matter lesions, deep brain haemorrhages, and cerebral microbleeds. The causes or mechanisms underlying these phenotypes are understood in varying degrees of detail. This review aims to summarize recent knowledge regarding these phenotypes and place it in context with classical clinicopathological observations to provide mechanistic, clinical, and therapeutic insights into small vessel disease.

Background and Purpose—Significantly increased blood pressure (BP) is common in patients receiving intravenous thrombolysis (IVT). We aimed to investigate frequency of pre- and post-treatment elevated BP and its relation to intracerebral hemorrhage (ICH) and symptomatic ICH (sICH), respectively.

BACKGROUND AND PURPOSE: Carotid IPH can be detected with MR imaging. The aim of this study was to determine the safety of CAS using an emboli protection device in patients with severe carotid artery stenosis and MR imaging–depicted carotid IPH.

BACKGROUND: It is not clear whether treatment modality (clipping or coiling) affects the risk of seizures after treatment for cerebral aneurysms. OBJECTIVE: To determine whether there is an increased risk of seizures after clipping vs coiling. Neurosurgery: September 2011 - Volume 69 - Issue 3 - pp 644-650 doi: 10.1227/NEU.0b013e31821bc46d.

SUMMARY: The Outreach DAC is an intermediate-sized catheter designed for use with the Merci clot retriever in acute stroke. We investigated its utility as an adjunctive device during AVM pedicle embolization. In the author s opinion, the DAC provided additional guide-catheter and microcatheter support, improved selective angiographic visualization of AVM angioarchitecture, aided microcatheter removal from its embedded position in the AVM Onyx cast, and enhanced local microcatheter control and safety, compared with embolization with the guide and microcatheter alone.

BACKGROUND AND PURPOSE: In clinical practice, durability of occlusion following coil embolization is superior in densely packed, compared with loosely packed, aneurysms. In a rabbit model, we probed, by using proteomics tools, the biologic mechanisms associated with densely packed and completely occluded aneurysms, compared with loosely packed and incompletely occluded aneurysms, to explore the biologic mechanisms of intra-aneurysmal healing following embolization.

Endovascular treatment for a wide-neck anterior communicating artery (AcomA) aneurysm remains technically challenging. Stent-assisted embolization has been proposed as an alternative of treatment of complex aneurysms. The X-configuration double-stent-assisted technique was used to achieve successful coiling of wideneck AcomA aneurysm. Implanted stent can alter intraarterial flow. Follow-up angiograms 4 months later showed flow changes due to used X-technique of stents implantation and filling of the anterior cerebral artery from the opposite internal carotid artery.

Background and Purpose—The development of comprehensive stroke centers within hub-and-spoke stroke networks offers the opportunity to increase the proportion of acute ischemic stroke patients treated with intra-arterial therapies (IAT). Interhospital transfer delays will be critical in evaluating the success of this strategy. Stroke. 2011; 42: 1626-1630 Published online before print April 28, 2011.

Atherosclerotic intracranial arterial stenosis is an important cause of stroke that is increasingly being treated with percutaneous transluminal angioplasty and stenting (PTAS) to prevent recurrent stroke. However, PTAS has not been compared with medical management in a randomized trial. This article (10.1056/NEJMoa1105335) was published on September 7, 2011, at NEJM .org.

The objective of this study was to compare the cerebral embolic load of filter-protected versus proximal balloon– protected carotid artery stenting (CAS).

Background and Purpose—Oral anticoagulants are effective at reducing stroke compared with aspirin in atrial fibrillation patients older than 75 years. Although the benefits of reduced stroke risk outweigh the risks of bleeding, the cost effectiveness of warfarin in this patient population has not yet been established.

BACKGROUND AND PURPOSE: Patients with ruptured brain AVMs are at considerable risk of repeat hemorrhage, particularly when associated intranidal or flow-related aneurysms are present. There is controversy about the timing of diagnosis and treatment of patients with hemorrhagic stroke. We present our results of endovascular treatment of ruptured AVMs in the acute phase.
