Small and broad-necked aneurysms are generally very difficult to treat using endovascular therapy. The arrival of the low-profile stent (e.g., Low-profile Visualized Intraluminal Support; LVIS) has enabled reconstructive treatment for these aneurysms. In addition, the bulging technique using LVIS is an effective and attractive technique for performing stent-assisted coiling to preserve parent arteries and achieve neck coverage. We report here a patient with a small and wide-necked ruptured basilar artery (BA) top aneurysm, in whom successful treatment was achieved by stent-assisted coiling with LVIS Jr...

BACKGROUND: Because the incidence of schwannoma arising from the parapharyngeal space (PPS) is very low, no studies have analyzed extirpation methods and postoperative neurological complications exclusively in PPS schwannomas. METHODS: The preoperative diagnosis and clinical outcomes of surgical treatment in 21 patients with PPS schwannoma who underwent surgery were investigated. RESULTS: Neurological deficit of the involved nerve developed in all patients regardless of the extirpation method used...

Cardiopulmonary bypass surgery is associated with a high incidence of neurological complications, including stroke, delirium and cognitive impairment. The development of strategies to reduce the incidence of such neurological events has been hampered by the lack of a clear understanding of their pathophysiology. Cerebral autoregulation (CA), which describes the ability of the brain to maintain a stable cerebral blood flow over a wide range of cerebral perfusion pressures despite changes in blood pressure, is known to be impaired in various neurological disorders...

OBJECTIVES: Although open repair is the standard surgical option for dissecting descending thoracic aneurysms (DTAs) and thoraco-abdominal aorta aneurysms (TAAAs), it remains a significant challenge with considerable perioperative morbidity and mortality. We retrospectively analysed early and late outcomes of open repair for these aortic aneurysms. METHODS: Early and late outcomes were investigated for 223 consecutive patients who underwent open repair for dissecting DTA or TAAA between January 2003 and December 2014 (mean age 55 ± 16 years)...

Recent literature strongly challenged indications to perform preventive surgery in unruptured AVM. claiming that invasive AVM treatment is associated with a significant risk of complications and thus conservative management may be a preferable alternative in many patients. On the other hand, the recent improvement of surgical instrumentation and treatment strategies (both surgical and interventional) yielded much better outcomes than those achieved only a decade ago. Therefore, even among the specialists, a wide variety of opinions, concerning the treatment of unruptured AVM, can be found...

Large lobar intracerebral hemorrhages (ICHs) can cause rapid neurological deterioration, and affected patients have low rates of survival and functional independence. Currently, the role of surgical intervention in the management patients with lobar ICHs is controversial. Minimally invasive technologies have been developed which may potentially decrease the operative morbidity of ICH surgery. The aim of this case report is to describe the technical aspects of the use of a novel minimally invasive endoport system, the BrainPath (NICO, Indianapolis, IN, USA), through an eyebrow incision for evacuation of a large lobar hematoma...

Sacral chordomas are slow-growing, indolent, and locally invasive tumors that typically present with pain and neurologic dysfunction. Wide en-bloc surgical excision is the primary treatment, but achieving adequate margins is difficult and surgery is often associated with significant morbidity. Adjuvant radiation therapy (RT) is utilized to decrease the risk of local recurrence or as definitive treatment for nonsurgical candidates. Although chordomas are considered to be relatively radioresistant tumors, several studies have demonstrated tumor response to high-dose proton therapy...

The purpose of this study was to review our experience with a single case of mastoiditis associated with sigmoid sinus thrombosis and increased intracranial pressure, and to review the experience of others through prior publications. We reviewed a case of a 6-year-old boy with an acute otitis media and mastoiditis, with associated ipsilateral sigmoid sinus and contralateral distal transverse sinus thrombosis. Based on the literature and our own experience, we conclude that most children with dural sinus thrombosis from acute otitis media and mastoiditis, in the setting of increased intracranial pressure, attain a good neurological outcome with a conservative neurosurgical approach...

Glioblastoma multiforme (GBM) is a malignant brain tumor with an ominous prognosis. The standard treatment includes maximal safe resection plus adjuvant therapy. Thalamic GBMs, however, are unfavorable for microsurgical removal because of deep location and proximity to critical structures. We present a patient presenting with progressive hemiparesis and decreased consciousness with a large thalamic GBM who underwent subtotal resection through a transsylvian approach. His clinical and neurologic condition improved after surgery and he survived nine months after surgery...

Surgery in and around eloquent brain structures poses a technical challenge when the goal of surgery is maximal safe resection. Magnetic resonance imaging (MRI) has revolutionized the diagnosis and treatment of neurological disorders, but tractography still remains limited in terms of utility because of the requisite manual labor and time required combined with the high risk of bias and inaccuracy. Automated whole brain tractography (AWBT) has simplified this workflow, overcoming historical barriers, and allowing for integration into modern neuronavigation...

BACKGROUND AND PURPOSE: Intrinsic T1-hyperintense signal has recently been reported in the deep gray nuclei on brain MR imaging after multiple doses of gadolinium-based contrast agents. Most reports have included adult patients and excluded those undergoing radiation or chemotherapy. We investigated whether T1 shortening is also observed in children and tried to determine whether radiochemotherapy is a risk factor for this phenomenon. MATERIALS AND METHODS: In this single-center retrospective study, we reviewed clinical charts and images of all patients 18 years of age or younger with ≥4 gadobenate dimeglumine-enhanced MRIs for 6 years...
