Objectives: The results at 30 days of early carotid endarterectomy (/=60% NASCET) were studied with a neurological audit.
Objectives: The recent creation of vascular neurology units (“stroke centers”) allowed the improvement of the management of the patients presenting a stroke (CVA), by decreasing the times of access to intravenous (IV) thrombolysis. The aim of this study was to show the feasibility, in the absence of specific recommendations, of the early surgical treatment of symptomatic carotid stenoses diagnosed after IV thrombolysis.
OBJECT: Using a database that enabled longitudinal follow-up, the authors assessed the long-term outcomes of unruptured cerebral aneurysms repaired by clipping or coiling.
OBJECT: The stroke rate, management, and outcome after blunt cerebrovascular occlusion (Biffl Grade IV injury) is not well defined, given the rarity of the disease. Both hemodynamic failure and embolic mechanisms have been implicated in the pathophysiology of subsequent stroke after blunt cerebrovascular occlusion. In this study, the authors evaluated their center´s experience with Biffl Grade IV injuries, focusing on elucidating the mechanisms of stroke and their optimal management.
OBJECT: Traumatic aneurysms occur in 10% of extracranial blunt traumatic cerebrovascular injuries (TCVI). The clinical consequences and optimal management of traumatic aneurysms are poorly understood.
OBJECT: Most patients with asymptomatic intracranial aneurysms treated with endovascular methods are closely observed overnight in an intensive care unit setting for complications, including ischemic and hemorrhagic stroke, cardiac dysfunction, and groin access complications. The purpose of this study was to analyze the timing, nature, and rate of in-house postoperative events.
OBJECT: As medical costs continue to rise during a time of increasing medical resource utilization, both hospitals and physicians must attempt to limit superfluous health care expenses. Neurointerventional treatment has been shown to be costly, but it is often the best treatment available for certain neuropathologies. The authors studied the effects of 3 policy changes designed to limit the costs of performing neurointerventional procedures at the University of Michigan.
OBJECT: Vertebrobasilar fusiform aneurysms (VFAs) are rare lesions characterized by abnormal dilation and tortuosity of the vertebral and/or basilar arteries. Untreated, these aneurysms have a tendency to progress, often resulting in neurological symptoms or rupture leading to subarachnoid hemorrhage. The microsurgical treatment of these lesions can be difficult due to their location and the circumferential involvement of the arteries. These features make microsurgical treatment prone to high morbidity. The Pipeline Embolization Device (PED) has gained popularity for the treatment of aneurysms of the internal carotid artery. Its use in the posterior circulation has been limited, likely due to a fear of perforating artery occlusion.
OBJECT: Intracranial aneurysms, especially those of the cavernous segment of the internal carotid artery (ICA), can present with cranial nerve (CN) palsies. The Pipeline Embolization Device (PED) has demonstrated safety and efficacy in the treatment of cerebral aneurysms by flow diversion, but little data exist reporting the outcomes of cranial neuropathies following treatment with the device.
OBJECT: The endovascular treatment of wide-necked aneurysms can be technically challenging due to distal coil migration or impingement of the parent vessel. In this paper, the authors illustrate an alternative method for the treatment of wide-necked intracranial aneurysms using a dual microcatheter technique.
OBJECT: Aneurysm recurrence after coil therapy remains a major shortcoming in the endovascular management of cerebral aneurysms. The need for long-term imaging follow-up was recently investigated. This study assessed the diagnostic yield of long-term digital subtraction angiography (DSA) follow-up and determined predictors of delayed aneurysm recurrence and retreatment.
BACKGROUND: Cerebral hyperperfusion syndrome sometimes occurs after carotid revascularization in patients with severe hemodynamic failure. To prevent cerebral hyperperfusion syndrome, cerebral hyperperfusion phenomenon (CHP) must be detected early. Single-photon emission computed tomography (SPECT) is useful for detecting CHP, but it is impractical on a daily basis. A tool with high availability to find CHP is desired.
BACKGROUND: Flow-diverting stents offer a promising treatment option for complex aneurysms.
BACKGROUND: Long-term outcomes associated with endovascular and surgical treatments for unruptured intracranial aneurysms are not well studied to date.
BACKGROUND: Accurate projection of implanted subdural electrode contacts in presurgical evaluation of pharmacoresistant epilepsy cases by invasive electroencephalography is highly relevant. Linear fusion of computed tomography and magnetic resonance images may display the contacts in the wrong position as a result of brain shift effects.
