BACKGROUND Neuroform stent-assisted coil embolization facilitates the endovascular treatment of wide-necked intracranial aneurysms. However, the safety and efficacy of its long-term use have not been fully elucidated. OBJECTIVE To retrospectively examine the long-term results of Neuroform stent usage in conjunction with coil embolization in wide-necked(More)
Neurofibromatosis type 2 (NF2) is an autosomal dominant syndrome with a prevalence of approximately 1 in 30,000. NF 2 is characterized by bilateral vestibular schwannomas, as well as meningiomas, ependymomas and gliomas. Currently, surgical resection and radiotherapy represent the mainstay of treatment, although new studies suggest a role for certain(More)
The existing literature on preoperative spine tumor embolization is limited in size of patient cohorts and diversity of tumor histologies. This report presents our experience with preoperative embolization of hypervascular thoracic, lumbar, and sacral spinal column tumors in the largest series to date. We conducted a retrospective review of 228 angiograms(More)
During the past few decades, there have been significant advances in the understanding of spinal vascular lesions, mainly because of the evolution of imaging technology and selective spinal angiography techniques. In this article, we discuss the classification, pathophysiology, and clinical manifestations of spinal vascular lesions other than DAVFs and(More)
OBJECTIVE To report a case of florid Cushing's hormone (ACTH) secretion related to the presence of an esthesioneuroblastoma (ENB). METHODS We present clinical, laboratory, and pathologic findings in a 36-year-old Caucasian man presenting with Cushing's syndrome. Results of computed tomography (CT), magnetic resonance imaging (MRI), positron emission(More)
BACKGROUND Cerebral vasospasm (VSP) is a major cause of morbidity and mortality associated with subarachnoid hemorrhage. The current endovascular paradigm for VSP refractory to medical therapy is to perform angioplasty for proximal vessel VSP and vasodilator infusion for distal vessel VSP. OBJECTIVE To report our experience with a large series of balloon(More)
Anoxic brain injury carries a poor prognosis. Therefore, a diagnostic tool sensitive enough to predict its outcome is needed. The authors describe the case of a 51-year-old woman who suffered cardiorespiratory arrest. Electroencephalography, somatosensory evoked potentials, and magnetic resonance imaging did not prove to be useful in establishing a(More)
Study Question: In patients with acute ischemic stroke, large vessel occlusion in the anterior circulation, and limited core infarct, what is the efficacy and safety of rapid revascularization with stent retrievers in conjunction with intravenous (IV) tissue plasminogen activator (tPA) versus IV tPA alone? In 2013, there were three major trials that were(More)
OBJECTIVE We introduce a technique that uses intraoperative flat-panel detector computed tomography (FD-CT) and three-dimensional rotational angiography (3D-RA) acquired in the hybrid operative suite to provide full neuronavigation capabilities during cerebrovascular surgery without the use of preoperative imaging studies. METHODS An Artis Zeego FD system(More)
