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)
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)
"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)
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)
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 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)
OBJECTIVES To determine the safety and tolerability of super-selective intra-arterial magnesium sulfate in combination with intra-arterial nicardipine in patients with cerebral vasospasm after subarachnoid hemorrhage. METHODS Patients were treated in a prospective protocol at two teaching medical centers. Emergent cerebral angiography was performed if(More)
Anomalous courses, anastomoses, and origins of the middle meningeal artery have often been described in the literature; however origin from the basilar artery or its branches is exceedingly rare with only five previous reports. We describe a middle meningeal artery originating from a large lateral pontine branch of the basilar artery. The lateral pontine(More)
Cervicocranial arterial dissection (CCAD) occurs when there is a tear in the intimal layer of the carotid or vertebral arteries with subsequent extravasation of blood into the subintimal layers. The dissection may be extradural, intradural, or extend over both segments. The contents of the subintimal layers are highly thrombogenic, and thus, embolism,(More)
