Onyx embolization of cerebral arteriovenous malformations (AVM) has become increasingly common. We explored the risk of seizures after Onyx use.A retrospective review was conducted of 20 patients with supratentorial brain arteriovenous malformation (AVM) who received Onyx embolization between 2006 and 2009. Baseline demographics, clinical history, seizure(More)
BACKGROUND Aneurysmal subarachnoid hemorrhage (SAH) with associated intracerebral hemorrhage (ICH) is often treated with concomitant surgical clipping and ICH evacuation. The aim of this study was to determine if aneurysm coiling followed by ICH evacuation is a viable alternative treatment. METHODS A retrospective review was conducted between July 2000(More)
OBJECTIVE Endoscopic skull base surgery has become increasingly popular among the skull base surgery community, with improved illumination and angled visualization potentially improving tumor resection rates. Intraoperative MRI (iMRI) is used to detect residual disease during the course of the resection. This study is an investigation of the utility of 3-T(More)
IgG4-related pachymeningitis is a serious inflammatory condition that can present with symptoms of mass effect and focal deficits. The first-line therapy is steroids and second-line is chemotherapy (methotrexate, azathioprine, etc.). We describe a patient with IgG4-related pachymeningitis in whom steroid use was contraindicated and methotrexate was(More)
OBJECT Approximately 250 million surgical procedures are performed annually worldwide, and data suggest that major complications occur in 3%-17% of them. Many of these complications can be classified as avoidable, and previous studies have demonstrated that preoperative checklists improve operating room teamwork and decrease complication rates. Although the(More)
Among the major complications of transsphenoidal surgery, less attention has been given to severe postoperative epistaxis, which can lead to devastating consequences. In this study, we reviewed 551 consecutive patients treated over a 4 year period by the senior author to evaluate the incidence, risk factors, etiology and management of immediate and delayed(More)
OBJECTIVE Stent-assisted coiling (SAC) of unruptured intracranial aneurysms is a treatment alternative to clipping or coiling, although high complication and procedure-related mortality rates have been reported. METHODS A retrospective study was conducted of patients undergoing SAC, coiling or clipping of unruptured intracranial aneurysms between 2003 and(More)
Ommaya reservoirs are routinely placed for the administration of intrathecal chemotherapy or antibiotics. There is scant literature that addresses the functionality of an Ommaya catheter placed exclusively within a cavum septum pellucidum (CSP). In this case, the authors placed an Ommaya reservoir in a 30-year-old man with Burkitt lymphoma in the CNS for(More)
BACKGROUND Little current data exists regarding outcome, cost, and length of stay (LOS) after subdural hemorrhage (SDH). We sought to examine predictors of discharge disposition, ICU and hospital LOS and direct, indirect, ICU, surgical, and diagnostic costs for SDH. METHODS A retrospective review was conducted of 216 SDH patients, aged >18 years admitted(More)
