Even though endovascular coils have been widely used for the treatment of intracranial aneurysms, the cellular and molecular responses of aneurysms to the coils after embolization remain poorly understood. The aim of the present study was to understand the mechanism of apoptosis in aneurysms embolized with platinum coils in the rabbit model of elastase-induced aneurysms. ⋯ Activation of apoptosis in aneurysms after embolization with platinum coils is induced by both tumor necrosis factor-alpha-mediated extrinsic and Bcl-2-mediated intrinsic pathways.

Randomized Controlled Trial
Therapeutic benefit of low-dose clopidogrel in patients undergoing carotid surgery is linked to variability in the platelet adenosine diphosphate response and patients' weight.
We have previously shown that a single 75-mg tablet of clopidogrel, taken before carotid endarterectomy, significantly reduces postoperative embolization, a marker of thromboembolic stroke. This study explores the antiplatelet effect of this submaximal dose. ⋯ These results explain how a single 75-mg dose of clopidogrel produces a significant clinical impact on embolization.

Randomized Controlled Trial Multicenter Study
Sequential-design, multicenter, randomized, controlled trial of early decompressive craniectomy in malignant middle cerebral artery infarction (DECIMAL Trial).
There is no effective medical treatment of malignant middle cerebral artery (MCA) infarction. The purpose of this clinical trial was to assess the efficacy of early decompressive craniectomy in patients with malignant MCA infarction. ⋯ In this trial, early decompressive craniectomy increased by more than half the number of patients with moderate disability and very significantly reduced (by more than half) the mortality rate compared with that after medical therapy.

Randomized Controlled Trial Multicenter Study
Decompressive Surgery for the Treatment of Malignant Infarction of the Middle Cerebral Artery (DESTINY): a randomized, controlled trial.
Decompressive surgery (hemicraniectomy) for life-threatening massive cerebral infarction represents a controversial issue in neurocritical care medicine. We report here the 30-day mortality and 6- and 12-month functional outcomes from the DESTINY trial. ⋯ DESTINY showed that hemicraniectomy reduces mortality in large hemispheric stroke. With 32 patients included, the primary end point failed to demonstrate statistical superiority of hemicraniectomy, and the projected sample size was calculated to 188 patients. Despite this failure to meet the primary end point, the steering committee decided to terminate the trial in light of the results of the joint analysis of the 3 European hemicraniectomy trials.

Migraine with aura is associated with ischemic stroke, but few studies have investigated the clinical and anatomic features of this association. We assessed the association of probable migraine with and without visual aura with ischemic stroke within subgroups defined by stroke subtype, vascular territory, probable migraine characteristics, and other clinical features. ⋯ PMVA was associated with an increased risk of stroke, particularly among women without other medical conditions associated with stroke. Behavioral risk factors, specifically smoking and oral contraceptive use, markedly increased the risk of PMVA, as did recent onset of PMVA.
