"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)
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)
We describe a case of traumatic pseudoaneurysm of the middle meningeal artery in a patient after a head trauma. The aneurysm was found incidentally and resolved spontaneously without any intervention; this outcome suggests that middle meningeal artery aneurysm may not require treatment in all cases and can be followed conservatively with follow-up(More)
BACKGROUND Lenticulostriate artery (LSA) aneurysms are uncommon. Most reported cases have been surgically treated. There are only three reports of LSA aneurysms treated with endovascular techniques. CASE DESCRIPTION We report the case of a 49-year-old man who presented with a hemorrhage in the basal ganglia. An angiogram revealed a distal LSA aneurysm in(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)
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)
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)
