BACKGROUND AND PURPOSE Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) is a marker of unstable atherosclerotic plaque, and is predictive of both primary and secondary stroke in population-based studies. METHODS We conducted a prospective study of patients with acute TIA who presented to the ED. Clinical risk scoring using the ABCD(2) score was(More)
"Diffuse correlation spectroscopy" (DCS) is a technology for non-invasive transcranial measurement of cerebral blood flow (CBF) that can be hybridized with "near-infrared spectroscopy" (NIRS). Taken together these methods hold potential for monitoring hemodynamics in stroke patients. We explore the utility of DCS and NIRS to measure effects of head-of-bed(More)
BACKGROUND AND PURPOSE A 6-point scoring system (ABCD) was described recently for stratifying risk after transient ischemic attack (TIA). This score incorporates age (A), blood pressure (B), clinical features (C), and duration (D) of TIA. A score <4 reportedly indicates minimal short-term stroke risk. We evaluated this scoring system in an independent(More)
Non-traumatic or spontaneous intracerebral hemorrhage (ICH) is defined as intra-parenchymal bleeding with or without extension into the ventricles and rarely into the subarachoid space. Primary ICH in most cases is associated with chronic hypertension. Acute hypertension is associated with hematoma expansion, and poor neurological outcome. The treatment of(More)
BACKGROUND We sought to determine whether measurement of D-dimer (DD) would improve risk stratification after transient ischemic attack (TIA). METHODS We enrolled 167 patients with acute TIA in a prospective observational study. DD was measured using rapid enzyme-linked immunosorbent assay. The primary outcome measure was a composite end point consisting(More)
OBJECTIVE Tenecteplase (TNK) is a third-generation thrombolytic agent. We evaluated the safety and feasibility of intra-arterial (IA) administration of TNK in patients with acute ischemic stroke. METHODS Patients who received endovascular treatment for acute ischemic stroke were identified from prospectively collected databases at three university(More)
OBJECTIVE The results of prematurely terminated stenting and aggressive medical management for preventing recurrent stroke in intracranial stenosis (SAMMPRIS) due to excessively high rate of stroke and death in patients randomized to intracranial stent placement is expected to affect the practice of endovascular therapy for intracranial atherosclerotic(More)
BACKGROUND In the treatment of acute ischemic stroke, intravenous (IV) recombinant tissue plasminogen (rt-PA) and intraarterial (IA) interventions are often combined. However, the optimal dose of IV rt-PA preceding endovascular treatment has not been established. METHODS Studies that used combined IV and IA thrombolysis were identified from a search of(More)
OBJECTIVE The results of Interventional Management of Stroke (IMS) III, Magnetic Resonance and REcanalization of Stroke Clots Using Embolectomy (MR RESCUE), and SYNTHESIS EXPANSION trials are expected to affect the practice of endovascular treatment for acute ischemic stroke. The purpose of this report is to review the components of the designs and methods(More)
OBJECTIVE To report experience with intra-arterial (IA) calcium channel blocker (nicardipine) in patients with acute ischemic stroke with and without reteplase, mechanical thrombectomy (snare), and primary angioplasty to achieve maximal recanalization. Selective delivery of calcium channel blocker may improve perfusion and possibly provide neuroprotection(More)
