BACKGROUND AND PURPOSE Endovascular therapy has increasingly become an acceptable option for treatment of unruptured aneurysms. To better understand the recent trends in the use of and outcomes related to coiling compared with clipping for unruptured aneurysms in the United States, we evaluated the NIS. MATERIALS AND METHODS Hospitalizations for clipping(More)
BACKGROUND AND PURPOSE The rate and outcomes of neurologic complications of patients receiving extracorporeal membrane oxygenation (ECMO) are poorly understood. The purpose of this study was to identify these parameters in ECMO patients. METHODS All patients receiving ECMO were selected from the Nationwide Inpatient Sample between 2001-2011. The rate and(More)
BACKGROUND Crossed cerebellar diaschisis is a rare finding of hemispheric cerebellar depression following contralateral cerebral injury, hypothesized to result from excessive neuronal excitatory synaptic activity along cortico-pontine-cerebellar pathways. The phenomenon is typically observed following ischemic stroke, but has also been characterized during(More)
Internal carotid artery pseudoaneurysm is an uncommon complication of retropharyngeal and parapharyngeal abscess in children. Treatment of the pseudoaneurysm has evolved in recent years from surgical ligation to endovascular techniques. Neurologic sequelae most commonly consist of Horner's syndrome with cerebral ischemia being uncommon. The clinical course(More)
OBJECTIVE Spinal epidural arteriovenous fistulas (SEDAVFs) constitute a rare but treatable cause of vascular myelopathy and are a different subtype from the more common Type I spinal dural AVFs. The purpose of this study was to review a consecutive series of SEDAVFs from a single institution and report on the clinical presentations, functional status, and(More)
BACKGROUND AND PURPOSE Takayasu arteritis is a rare, large-vessel vasculitis that presents with symptoms related to end-organ ischemia. While the extracranial neurovascular manifestations of Takayasu arteritis are well-established, little is known regarding the intracranial manifestations. In this study, we characterize the intracranial and cervical(More)
BACKGROUND AND PURPOSE Among patients with vertebrobasilar dolichoectasia is a subset of patients with disease affecting the anterior circulation as well. We hypothesized that multivessel intracranial dolichoectasia may represent a distinct phenotype from single-territory vertebrobasilar dolichoectasia. The purpose of this study was to characterize clinical(More)
BACKGROUND Contrast-induced encephalopathy (CIE) is a syndrome that may be clinically unrecognized and misdiagnosed as cerebral edema. METHODS Case report and review. RESULTS A 72-year-old woman was admitted for elective endovascular embolization of a 10-mm left anterior communicating artery aneurysm. One hour post-procedure, she acutely developed(More)
BACKGROUND AND PURPOSE Spinal dural arteriovenous fistulas are commonly missed on imaging or misdiagnosed as inflammatory or neoplastic processes. We reviewed a consecutive series of spinal dural arteriovenous fistulas referred to our institution that were missed or misdiagnosed on initial imaging and studied the clinical consequences of missing or(More)
