Fluorescent Molecular Peroxidation Products: A Prognostic Biomarker of Early Neurologic Deterioration After Thrombolysis Clinical Sciences
Conclusions— FMPPs might be a valuable biomarker of poor early neurological outcome and be related to the appearance of symptomatic intracranial hemorrhage in tissue plasminogen activator–treated patients, one of the most feared neurological complications after thrombolytic treatment of acute ischemic stroke.

Nascent Deep Microbleeds and Stroke Recurrences
This study investigated the contributions of nascent deep MBs to stroke recurrence.Methods: We prospectively analyzed nascent deep MBs in patients admitted to our hospital who were treated for index strokes between April 2004 and November 2009. The number of nascent deep MBs was counted on T2∗-weighted MRI scans around 1 year after the index strokes, and compared to previous MRIs on admission. Stroke recurrence–free rate curves were generated using the Kaplan–Meier method using the log-rank test. The odds ratio for nascent deep MBs was derived using a multivariate logistic regression model that was based on recurren...

Intravenous Thrombolysis Resulting In Acute Ischemic Stroke Recanalization Can Lead To Cerebral Hyperperfusion Syndrome (P7.123)

Investigating the Utility of Previously Developed Prediction Scores in Acute Ischemic Stroke Patients in the Stroke Belt
Conclusions: Our study demonstrated that although highly predictive of outcome in the original study design treatment groups, prediction scores may not generalize to all patient samples, highlighting the importance of validating prediction scores in diverse samples.

MRI Guiding of the Middle Cerebral Artery Occlusion in Rats Aimed to Improve Stroke Modeling
AbstractThe middle cerebral artery occlusion (MCAO) model in rats closely imitates ischemic stroke and is widely used. Existing instrumental methods provide a certain level of MCAO guidance, but monitoring of the MCA-occluding intraluminal filament position and possible complications can be improved. The goal of this study was to develop a MRI-based method of simultaneous control of the filament position, blood flow in the intracranial vessels, and hemorrhagic complications. Rats were subjected to either MRI-guided MCAO (group 1,n = 51) or MCAO without MRI control (group 2,n = 38). After operation, group 1 rats wer...

Effects of Candesartan in the Acute Phase of Intracerebral Hemorrhage
Background and Purpose: Uncertainty persists over the effects of blood pressure-lowering treatment in acute intracerebral hemorrhage (ICH). We assessed the effects of treatment with candesartan in acute ICH and according to different types of hematoma. Methods: Post-hoc analysis of the Scandinavian Candesartan Acute Stroke Trial, a randomized- and placebo-controlled, double-masked trial of candesartan in patients with any stroke within the acute phase (

Intravenous Tissue Plasminogen Activator Therapy for an Acute Ischemic Stroke Patient with Later Diagnosed Unilateral Moyamoya Syndrome
We report the use of intravenous tissue plasminogen activator (t-PA) therapy in a 38-year-old patient who was later diagnosed with unilateral moyamoya syndrome. The patient had a sudden onset of unconsciousness, vomiting, dysarthria, and tetraparesis. A neurologic examination revealed consciousness disturbance, right central facial nerve palsy, dysarthria, and tetraparesis with bilateral exotropia and horizontal gaze palsy. A magnetic resonance imaging scan on admission did not reveal fresh cerebral infarction or hemorrhage, but magnetic resonance angiography revealed severe stenosis at the terminal portion of left interna...

CSF and Serum Biomarkers Focusing on Cerebral Vasospasm and Ischemia after Subarachnoid Hemorrhage.
Authors: Jung CS, Lange B, Zimmermann M, Seifert V Abstract Delayed cerebral vasospasm (CVS) and delayed cerebral ischemia (DCI) remain severe complications after subarachnoid hemorrhage (SAH). Although focal changes in cerebral metabolism indicating ischemia are detectable by microdialysis, routinely used biomarkers are missing. We therefore sought to evaluate a panel of possible global markers in serum and cerebrospinal fluid (CSF) of patients after SAH. CSF and serum of SAH patients were analyzed retrospectively. In CSF, levels of inhibitory, excitatory, and structural amino acids were detected by high-performan...

Endovascular treatment for M2 occlusions in the era of stentrievers: a descriptive multicenter experience
Conclusions Endovascular treatment of M2 MCA occlusion with stentrievers seems safe. Induced recanalization may double the chances of achieving a favorable outcome, especially for patients with moderate or severe deficit.

Intravenous Thrombolysis for Acute Ischemic Stroke in Patients with Thrombocytopenia (P4.264)
Conclusions:IV rtPA for AIS might be safe in patients with platelet count <100,000/mm3 and it is reasonable not to delay IV rtPA administration while waiting for the platelet count result, unless there is strong suspicion for abnormal platelet count .Disclosure: Dr. Mowla has nothing to disclose.

Subacute Elevation of Plasma Level of Caspase-Cleaved Cytokeratin-18 is Associated with Hemorrhagic Transformation and Functional Outcome in Ischemic Stroke
Background: Caspase-cleaved cytokeratin-18 (CCCK-18) is an apoptosis marker. Here, we analyzed the relationship between plasma level of CCCK-18 in the acute and subacute stage of ischemic stroke and early and late functional outcome. Besides, correlation among CCCK-18 and complications, such as hemorrhagic transformation (HT) were also explored. Methods: Plasma concentration of CCCK-18 was investigated in 54 patients at admission and poststroke 72 hours. HT was evaluated by CT scans on 24 poststroke hours.

Cardiac Arrhythmias and Acute Cerebrovascular Events: A Case of QT Prolongation and Torsades de Pointes Early After Right Insular Stroke
Stroke involving some areas of the cerebral hemisphere, such as insula, amygdala, and lateral hypothalamus, may cause changes in autonomic control of cardiac function. A 58-year-old woman presented to the emergency department for acute onset of left facial-brachial-crural hemiparesis and dysarthria. A brain CT scan showed subacute ischemic lesion with hemorrhagic infarction in right insular-rolandic cortex. Over the next few days ECG showed severe bradycardia with elongation of QTc, significative pauses (5 seconds), runs of nonsustained ventricular tachycardia and torsades de pointes.
