Prognostic Value of Various Hemostasis Parameters and Neurophysiological Examinations in Spontaneous Intracerebral Hemorrhage: The IRONHEART Study Protocol
Discussion: If associations between outcomes and the investigated parameters (hemostasis and neurophysiological examinations) are confirmed, results might aid prognosis assessment in this subtype of stroke with particularly high mortality. Improving clinical grading systems on ICH severity and outcomes by including the investigated parameters could help to better guide the management of these patients in the future.

Carotid Artery Free-Floating Thrombus Caused by Paradoxical Embolization From Greater Saphenous Vein Ascending Thrombophlebitis
We report a case of a young woman without cardiovascular risk factors who was admitted to our emergency department with listlessness and altered mental status. The clinical examination revealed right lower limb swelling. Magnetic resonance imaging and contrast-enhanced computed tomographic scans revealed a free floating thrombus of the left internal carotid artery (ICA) with a large bilateral frontal ischemic lesion. The diagnosis of a medium-sized PFO with moderate right-to-left contrast shunting was made after transesophageal echocardiography. No other cardiac sources for embolization were detected, while an ascending th...

Successful recanalization post endovascular therapy is associated with a decreased risk of intracranial haemorrhage: a retrospective study
Background: The risks of intracranial haemorrhage (ICH) post intra-arterial therapy (IAT) for stroke are not well understood. We aimed to study the influence of recanalization status post IAT for anterior circulation stroke and posterior circulation stroke on ICH development. Methods: Retrospective analysis of 193 patients in a prospectively collected database of IAT stroke patients was performed. Successful recanalization was defined as a Thrombolysis in Cerebral Infarction Score of 2b or 3 and symptomatic ICH (SICH) as parenchymal hematoma type 2 (PH2) with neurological deterioration. The association between the recanali...

Association between hemorrhagic transformation after endovascular therapy and poststroke seizures
Summary ObjectiveEndovascular therapy has recently become standard therapy for select patients with acute ischemic stroke. Infarcted brain tissue may undergo hemorrhagic transformation (HT) after endovascular therapy. We investigated the association between HT and occurrence of poststroke seizures in patients treated with endovascular therapy. MethodsConsecutive patients treated with endovascular therapy for acute anterior circulation ischemic stroke were included. HT was assessed with computed tomography/magnetic resonance imaging (CT/MRI) at 24 h after stroke onset. Patients were followed for up to 2 years for seizure oc...

Efficacy of intra-arterial therapy in the elderly requires further study
We salute Dr Ghobrial and colleagues for their important contribution regarding the endovascular management of elderly ischemic stroke patients.1 Although this topic is relatively new to the literature, it is of critical importance to the field of intra-arterial therapy (IAT), given the increasing use of catheter based stroke therapies2 and the expanding population of elderly Americans who are at the highest risk for ischemic stroke. The authors conducted an extensive, retrospective, single center study using chart review that identified elderly patients (aged >75 years) that underwent IAT between 2006 and 2012. Th...

O-025 The Superiority of Thrombectomy over IV rtPA Monotherapy May be Associated with Thrombus Length - Results of the THERAPY Trial
ConclusionExtensive thrombus burden presents a challenge for stroke intervention, posing greater risk of complications and poor clinical outcome. However, this effect is dampened when IAT is the interventional modality, leading to a more favorable prognosis over IV-rtPA alone. This study finding supports the use of aspiration thrombectomy in treatment of extended thrombi, demonstrating relative advantages over thrombolytic monotherapy, and enables better clinical outcomes.DisclosuresR. von Kummer: 2; C; Penumbra, Inc.

Neutrophil-to-Lymphocyte Ratio Is an Independent Predictor for In-Hospital Mortality in Spontaneous Intracerebral Hemorrhage
Background and Purpose: Stroke-associated immunosuppression and inflammation are increasingly recognized as factors that trigger infections and thus, potentially influence the outcome after stroke. Several studies demonstrated that elevated neutrophil-to-lymphocyte ratio (NLR) is a significant predictor of adverse outcomes in patients with ischemic stroke. However, little is known about the impact of NLR on short-term mortality in intracerebral hemorrhage (ICH).Methods: This observational study included 855 consecutive ICH-patients. Patient demographics, clinical, laboratory, and in-hospital measures as well as neuroradiol...

The use of serum glial fibrillary acidic protein test as a promising tool for intracerebral hemorrhage diagnosis in Chinese patients and prediction of the short-term functional outcomes
The objective of this study was to explore the efficacy of glial fibrillary acidic protein (GFAP) in differentiating intracerebral hemorrhage (ICH) from ischemic stroke (IS). Suspicious patients of acute stroke were screened and finally diagnosed by computed tomography and magnetic resonance imaging. Blood samples were collected within 2–6 h after onset of symptoms, and serum GFAP level was determined by ELISA assay. The functional outcome for the patients was determined by modified Rankin Scale (mRS) 90 days after onset of symptoms. 43 ICH patients and 65 IS patients were enrolled. GFAP concentration in ICH group was ...
