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)
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)
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)
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)
Percutaneous stenting techniques are becoming more commonly used for treatment of carotid artery disease. One outcome of particular concern is in-stent restenosis. Indications for treatment of in-stent restenosis are not clearly defined. Use of traditional balloon angioplasty with or without stent placement is still considered the first option. Cutting(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)
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)
INTRODUCTION Acute carotid artery occlusion carries a high morbidity and mortality. Acute angioplasty and stenting is a feasible option with little known about the long term outcome. Limiting factor for this approach is hyperperfusion syndrome or hemorrhagic infarction. Spontaneous early or late recanalization for extracranial vessel is in the range of 5%(More)
INTRODUCTION Approximately 20-30% of the patients with acute ischemic stroke do not have any occlusion demonstrated on initial digital subtraction angiography (DSA). We sought to determine the risk and rates of cerebral infarction and favorable neurological outcome in this group of acute ischemic stroke patients. MATERIALS AND METHODS Patients were(More)
Giant cell arteritis (GCA) is the most common form of systemic vasculitis in adults. Patients usually present with headache and visual symptoms, and have an elevated erythrocyte sedimentation rate. It has been reported that 3-4% of patients with GCA develop ischemic events secondary to vertebral artery stenosis or occlusion. The mainstay of therapy of GCA(More)
