OBJECT Intracranial atherosclerotic disease (ICAD) carries a high risk of stroke. Evaluation of ICAD has focused on assessing the absolute degree of stenosis, although plaque morphology has recently demonstrated increasing relevance. The authors provide the first report of the use of ultra-high-resolution C-arm cone-beam CT angiography (CBCT-A) in the(More)
Object The traditional methods for managing symptomatic chronic subdural hematoma (SDH) include evacuation via a bur hole or craniotomy, both with or without drain placement. Because chronic SDH frequently occurs in elderly patients with multiple comorbidities, the bedside approach afforded by the subdural evacuating port system (SEPS) is an attractive(More)
OBJECTIVE Headache and neck pain are common postpartum symptoms. However, these symptoms can rarely be associated with internal carotid artery and vertebral artery dissections. We aimed to review five cases of postpartum cervical artery dissection and to review the clinical course of previously reported cases. METHODS Patients with postpartum dissections(More)
BACKGROUND AND PURPOSE The middle cerebral artery (MCA) bifurcation is a preferred site for aneurysm formation. Wider bifurcation angles have been correlated with increased risk of aneurysm formation. We hypothesized a link between the presence of MCA aneurysms and the angle morphology of the bifurcation. METHODS Three-dimensional rotational angiography(More)
Adolescent users of 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) may escalate their dose because of the development of tolerance. We examined the influence of intermittent adolescent MDMA exposure on the behavioral, physiological, and neurochemical responses to a subsequent MDMA "binge" or to a 5-hydroxytryptamine(1A) (5-HT(1A)) receptor challenge.(More)
BACKGROUND Although intracranial stenting has been associated with in-stent stenosis, the vascular response of cerebral vessels to the deployment of the Enterprise vascular reconstruction device is poorly defined. OBJECTIVE To evaluate the change in parent vessel caliber that ensues after Enterprise stent placement. METHODS Seventy-seven patients with(More)
Epidermoid cysts are rare lesions accounting for 1% of intracranial tumors with approximately 50% located within the cerebello-pontine angle (CPA). Resection is complicated by their close anatomical relation to critical neurovascular structures and their tendency to be densely adherent making complete removal a significant neurosurgical challenge. We(More)
UNLABELLED OBJECT.: The benefits of treating intracranial aneurysms in the region of the anterior visual pathways are well understood. However, the adverse effects of endovascular stenting across the ophthalmic artery have received little attention. The authors reviewed their experience with patients who had stents deployed across the ophthalmic artery(More)
Several stent-supported coiling techniques have been devised for treating wide-necked bifurcation aneurysms including the Y-stent and waffle-cone constructs. The Y-stent technique is not technically possible with obtusely oriented daughter vessels, and the waffle-cone method is inadequate for aneurysms with necks exceeding the stent's maximal expansion(More)
Arachnoid cysts are common, accounting for approximately 1% of intracranial mass lesions. Most are congenital, clinically silent, and remain static in size. Occasionally, they increase in size and produce symptoms due to mass effect or obstruction. The mechanism of enlargement of arachnoid cysts is controversial. One-way slit valves are often hypothesized(More)
