STROKE. Clinical Sciences. The VASOGRADE. A Simple Grading Scale for Prediction of Delayed Cerebral Ischemia After Subarachnoid Hemorrhage

Background and Purpose: Patients are classically at risk of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage. We validated a grading scale—the VASOGRADE—for prediction of DCI.

STROKE. Clinical Sciences. Long-Term Excess Mortality After Aneurysmal Subarachnoid Hemorrhage

Background and Purpose: There is high case-fatality rate and loss of productive life-years related to aneurysmal subarachnoid hemorrhage (aSAH) but data on long-term survival of patients with aSAH are scarce. We aim to evaluate long-term excess mortality and related risk factors after an aSAH event.

STROKE. Clinical Sciences. Recovery to Preinterventional Functioning, Return-to-Work, and Life Satisfaction After Treatment of Unruptured Aneurysms

Background and Purpose: The eventual goal of preventive treatment of unruptured intracranial aneurysms is to increase the number of life years with high life satisfaction. Insight in the time with reduced functioning, working capacity, and life satisfaction after aneurysm treatment is pivotal to balance the pros and cons of preventive aneurysm occlusion.

STROKE. Clinical Sciences. Relative Influence of Capillary Index Score, Revascularization, and Time on Stroke Outcomes From the Interventional Management of Stroke III Trial

Background and Purpose: Until recently, acute ischemic stroke (AIS) trials have failed to show a benefit of endovascular therapy compared with standard therapy, leading some authors to recommend decreasing the time from ictus to revascularization to improve outcomes. We hypothesize that improving patient selection using the capillary index score (CIS) may also be a useful strategy.

STROKE. Clinical Sciences. Reperfusion Within 6 Hours Outperforms Recanalization in Predicting Penumbra Salvage, Lesion Growth, Final Infarct, and Clinical Outcome

Background and Purpose: The relative merits of reperfusion versus recanalization to predict tissue and clinical outcomes in anterior circulation stroke have been previously assessed using data acquired >12 hours postonset. To avoid late-occurring confounders such as non-nutritional reperfusion, futile recanalization and no-reflow phenomenon, we performed ultraearly assessment of reperfusion and recanalization.

STROKE. Clinical Sciences. Is Visual Evaluation of Aneurysm Coiling a Reliable Study End Point?

Background and Purpose: Angiographic occlusion as a surrogate marker of satisfactory aneurysm treatment is commonly used in clinical trials although some pitfalls have to be considered. To investigate the inter-rater reliability of visual rating of aneurysm occlusion as study end point, we performed a systematic review and meta-analysis.

RSNA: Radiology. Stent-assisted Coil Placement for the Treatment of 211 Acutely Ruptured Wide-necked Intracranial Aneurysms: A Single-Center 11-Year Experience

Purpose: To evaluate the safety and angiographic and clinical outcome of stent-assisted coil placement (SACP) for acutely ruptured wide-necked intracranial aneurysms treated in a single center during an 11-year period.

AMERICAN JOURNAL OF NEURORADIOLOGY. Degree of Collaterals and Not Time Is the Determining Factor of Core Infarct Volume within 6 Hours of Stroke Onset

BACKGROUND AND PURPOSE: Growth of the core infarct during the first hours of ischemia onset is not well-understood. We hypothesized that factors other than time from onset of ischemia contribute to core infarct volume as measured by MR imaging.

AMERICAN JOURNAL OF NEURORADIOLOGY. Deconstructive and Reconstructive Techniques in Treatment of Vertebrobasilar Dissecting Aneurysms: A Systematic Review and Meta-Analysis

BACKGROUND AND PURPOSE: Various endovascular techniques have been applied to the treatment of vertebrobasilar dissecting aneurysms, including parent artery preservation with coiling, stent placement or flow diverter placement, and trapping and proximal occlusion. We performed a systematic review and meta-analysis to study clinical and angiographic outcomes of patients undergoing endovascular treatment of vertebrobasilar dissecting aneurysms.

NEUROSURGERY. Morphological Parameters Associated With Middle Cerebral Artery Aneurysms

BACKGROUND: Morphological factors contribute to the hemodynamics of the middle cerebral artery (MCA).

NEUROSURGERY. Time Course and Risk Factors for Myocardial Dysfunction After Aneurysmal Subarachnoid Hemorrhage

BACKGROUND: Myocardial wall motion abnormalities (WMAs) are independent risk factors for a poor outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH).

NEUROSURGERY. A Retrospective Comparison of the Influence of Surgical Clipping and Endovascular Embolization on Recovery of Oculomotor Nerve Palsy in Patients With Posterior Communicating Artery Aneurysms

BACKGROUND: Oculomotor nerve palsy (ONP) is a common symptom of posterior communicating artery aneurysms (PcomAAs). Surgical clipping and endovascular embolization are used to treat PcomAAs with ONP.

NEUROSURGERY. Endovascular Treatment and the Outcomes of Atherosclerotic Intracranial Stenosis in Patients With Hyperacute Stroke

BACKGROUND: The importance of underlying atherosclerotic intracranial artery stenosis (ICAS) in hyperacute stroke patients who receive endovascular therapy remains unknown.

NEUROSURGERY. Time Is Brain and So Is Less Blood: The Hyperacute Period After Intracerebral Hemorrhage

Intracerebral hemorrhage (ICH) is associated with a significant risk of neurological deterioration (ND).1-3 It is estimated that ND can occur in up to 33% of patients with ICH. Large-volume hematomas (>45 mL), hematoma expansion, hypertension, and spot sign on computed tomography (CT) are significant risk factors for developing ND.
