BACKGROUND: Trigeminal nerve atrophy and neurovascular compression (NVC) are frequently observed in classical trigeminal neuralgia (CTN). OBJECTIVE: To determine whether nerve characteristics contribute to Gamma Knife (Elekta AB, Stockholm, Sweden) surgery (GKS) outcomes in unilateral CTN without previous surgery. METHODS: From 2006 to 2012, 67 patients with unilateral CTN without previous surgery received GKS with a maximal dose of 90 Gy delivered to the trigeminal nerve juxta brainstem...

BACKGROUND: Brain cavernous angiomas with symptomatic hemorrhage (CASH) are uncommon but exact a heavy burden of neurological disability from recurrent bleeding, for which there is no proven therapy. Candidate drugs to stabilize the CASH lesion and prevent rebleeding will ultimately require testing of safety and efficacy in multisite clinical trials. Much progress has been made in understanding the epidemiology of CASH, and novel biomarkers have been linked to the biological mechanisms and clinical activity in lesions...

BACKGROUND: Stenting and flow diversion for aneurysmal sub arachnoid hemorrhage (aSAH) require the use of dual antiplatelet therapy (DAPT). OBJECTIVE: To investigate whether DAPT is associated with hemorrhagic complication following placement of external ventricular drains (EVD) in patients with aSAH. METHODS: Rates of radiographically identified hemorrhage associated with EVD placement were compared between patients who received DAPT for stenting or flow diversion, and patients who underwent microsurgical clipping or coiling and did not receive DAPT by way of a backward stepwise multivariate analysis...

BACKGROUND: Surgery remains an integral part of the treatment of medulloblastoma. We present our experience with repeat surgery for this tumor before initiation of adjuvant therapy. OBJECTIVE: To report what was found intraoperatively and where at time of second-look surgery and detail any postoperative events or readmissions within 90 days of surgery. METHODS: Two separate institutional databases were queried to identify patients who underwent repeat resection of suspected residual medulloblastoma from January 2003 to January 2017...

Currently, there is an incomplete understanding of the molecular pathogenesis of meningiomas, the most common primary brain tumor. Several familial syndromes are characterized by increased meningioma risk, and the genetics of these syndromes provides mechanistic insight into sporadic disease. The best defined of these syndromes is neurofibromatosis type 2, which is caused by a mutation in the NF2 gene and has a meningioma incidence of approximately 50%. This finding led to the subsequent discovery that NF2 loss-of-function occurs in up to 60% of sporadic tumors...

BACKGROUND: Examining the costs of single- and multilevel anterior cervical discectomy and fusion (ACDF) is important for the identification of cost drivers and potentially reducing patient costs. A novel tool at our institution provides direct costs for the identification of potential drivers. OBJECTIVE: To assess perioperative healthcare costs for patients undergoing an ACDF. METHODS: Patients who underwent an elective ACDF between July 2011 and January 2017 were identified retrospectively...

BACKGROUND: Ten-year follow-up data from the US Food and Drug Administration investigational device exemption trial comparing BRYAN® Cervical Disc (Medtronic, Dublin, Ireland) arthroplasty to anterior cervical discectomy and fusion (ACDF) demonstrated that disc arthroplasty maintained range of motion and improvements in overall success and neck disability. OBJECTIVE: To compare the 10-yr rates of symptomatic adjacent level disease requiring surgery (SALDRS). METHODS: Prospective randomized trial data were analyzed comparing BRYAN® Cervical Disc arthroplasty to ACDF for single-level cervical disc disease with concordant radiculopathy or myelopathy with clinicoradiographic analysis at 10 yr...

BACKGROUND: Cytoreductive surgery is considered controversial for primary central nervous system lymphoma (PCNSL). OBJECTIVE: To investigate survival following craniotomy or biopsy for PCNSL. METHODS: The National Cancer Database-Participant User File (NCDB, n = 8936), Surveillance, Epidemiology, and End Results Program (SEER, n = 4636), and an institutional series (IS, n = 132) were used. We retrospectively investigated the relationship between craniotomy, prognostic factors, and survival for PCNSL using case-control design...

BACKGROUND: Increased body mass index (BMI) may be protective against cerebral ischemia in certain clinical contexts. OBJECTIVE: To investigate whether increased BMI was associated with delayed cerebral ischemia (DCI) and subsequent infarction after aneurysmal subarachnoid hemorrhage (aSAH). METHODS: We retrospectively reviewed the clinical course of patients presenting to our institution for management of aSAH. Patient were segregated according to BMI< or ≥29...

BACKGROUND: It is assumed that high pore densities in flow diverters (FDs) are beneficial for intracranial aneurysm (IA) healing. However, various animal studies are not conclusive on the issue, suggesting that other factors are in play. One important factor might be wall apposition. OBJECTIVE: To (1) determine the relationship between FD pore density and aneurysm occlusion, and (2) determine the relationship between FD wall apposition and aneurysm occlusion. METHODS: Saccular aneurysms were microsurgically created in the aorta of 36 Wistar rats...

BACKGROUND: Patient satisfaction ratings are increasingly used for hospital rankings, referral base and physician reimbursement. As such, online physician rating websites (PRWs) are quickly becoming a topic of interest. OBJECTIVE: To analyze the distribution of neurosurgeons' ratings on the 3 most widely used PRWs, and examine factors associated with positive and negative ratings. METHODS: We used a key term search to identify board-certified neurosurgeons on 3 widely used PRWs: RateMD...

BACKGROUND: Image guidance is a promising technology that could lead to lower rates of premature shunt failure by decreasing the rate of inaccurate proximal catheter placement. OBJECTIVE: To perform a detailed radiographic analysis of ventricular size using 3 well-described methods and compare proximal revision rates. METHODS: Our shunt surgery research database was queried to identify procedures (new placement or revision) where frameless stereotactic electromagnetic neuronavigation was used (January 2010-June 2016)...

BACKGROUND: Brain tumors in the first year of life are rare and their management remains challenging. OBJECTIVE: To report on the contemporary management of brain tumors in infants with reference to previous series from our institution. METHODS: Retrospective cohort study design.

BACKGROUND: The Neurologic Assessment in Neuro-Oncology (NANO) scale is a standardized objective metric designed to measure neurological function in neuro-oncology. Current neuroradiological evaluation guidelines fail to use specific clinical criteria for progression. OBJECTIVE: To determine if the NANO scale was a reliable assessment tool in glioblastoma (GBM) patients and whether it correlated to survival. METHODS: Our group performed a retrospective review of all patients with newly diagnosed GBM from January 1, 2010, through December 31, 2012, at our institution...
