Abstract BACKGROUND Ventriculoperitoneal shunt (VP-shunt) is the standard of treatment for idiopathic normal pressure hydrocephalus (iNPH). However, a thorough investigation VP-shunt complications in this population lacking. OBJECTIVE To present analysis and rates progressively occurring during first year after surgery patients with iNPH included European multicenter (EU-iNPH) study. METHODS Patients (n = 142) were prospectively EU-iNPH study by 13 institutions. All received programmable...
In the present study, we aimed to test association between correct function of left ventral white matter pathways and semantic processing (dual stream models for language processing, Hickok & Poeppel, 2004), using a new set tasks during intraoperative electrical stimulation at level. Additionally, evaluated brain regions needed performance on different lesion-symptom analyses (voxel mapping track-wise lesion analysis) in sample 62 candidates awake surgery. We found that vicinity inferior...
OBJECTIVE Subcortical electrical stimulation during brain surgery may allow localization of functionally crucial white matter fibers and thus tailoring the tumor resection according to its functional limits. The arcuate fasciculus (AF) is a bundle connecting frontal, temporal, parietal cortical areas that often disrupted by left lesions. It plays critical role in several cognitive functions related phonological processing, but current intraoperative monitoring methods do not yet mapping this...
Little is known regarding the optimal treatment of ventriculoperitoneal (VP) shunt infections in adults. Our aim was to assess efficacy strategies and identify factors that predict failure.Retrospective, observational study patients aged ≥12 years with VP (1980 -2014). Therapeutic approaches were classified under 4 headings: only antibiotics (OA), one-stage replacement (OSSR), two-stage (TSSR), removal without (SR). The primary endpoint failure strategy, defined as absence definite...
The Supplementary Motor Area (SMA)-located in the superior and medial aspects of frontal gyrus-is a preferential site certain brain tumors arteriovenous malformations, which often provoke so-called SMA syndrome. bulk literature studying this syndrome has focused on two its most apparent symptoms: contralateral motor speech deficits. Surprisingly, little attention been given to working memory (WM) even though neuroimaging studies have implicated cognitive process. Given relevance for...
OBJECTIVE Brain metastases are the most frequent intracranial malignant tumor in adults. Surgical intervention for eloquent areas remains controversial and challenging. Even when not infiltrating intra-parenchymal tumors, can be affected. Therefore, this study aimed to describe role of a functional guided approach resection brain central region. METHODS Thirty-three patients (19 men 14 women) with perirolandic who were treated at authors' institution reviewed. All participants underwent...
The occurrence of seizures after aneurysmal subarachnoid hemorrhage (aSAH) is associated with a poorer functional and cognitive prognosis less favorable quality life. It would be value to promptly identify patients at risk epilepsy optimize follow-up protocols design preventive strategies. Our aim was develop predictive score help stratify in aSAH.
Microsurgical resection of arteriovenous malformations (AVMs) located in the language and motor cortex is associated with risk neurological deterioration, yet electrocortical stimulation mapping has not been widely used.To demonstrate usefulness intraoperative language/motor AVMs.During an 11-year period, was used 12 431 patients (2.8%) undergoing AVM (5 7 AVMs). Language performed under awake anesthesia general anesthesia.Identification a functional enabled its preservation 11 (92%), guided...
To assess improvements in Glasgow Outcome Scale (GOS) and GOS extended (GOSE) scores between 6 months 1 year following severe traumatic brain injury (TBI).One studied 214 adult patients with TBI Coma (GCS) <9 admitted to Intensive Care Unit (ICU). were obtained 12 after 195 subjects. Patients predominantly male (84%) median age was 35 years.Outcome (GOS GOSE at year) better the high GCS score admission (6-8) group than low (3-5). The improvement greater group. At months, 75 had died 120...
Abstract BACKGROUND Intraoperative identification and preservation of the corticospinal tract is often necessary for glioma resection. OBJECTIVE To make a proposal intraoperative management with high-frequency monopolar stimulation technique monitoring tract. METHODS Ninety-two patients operated on assistance stimulation. Clinical neurophysiological data have been related motor status at 3 months to establish prognostic factors deterioration. RESULTS Twenty-one (22.8%) presented alterations...
To investigate decision-making deficits after anterior communicating artery aneurysm (ACoA) rupture and to compare the effects of two treatments.The sample included 40 patients with subarachnoid hemorrhage secondary ruptured ACoA a favorable neurological outcome control group 31 subjects matched by age, sex, years education. Twenty had surgical interventions (clipping) 20 received endovascular treatment. Decision-making was assessed Iowa Gambling Task (IGT). We used Expectancy Valence model...
OBJECT Little attention has been given to the functional challenges of insular approach resection gliomas, despite potential damage essential neural networks that underlie insula. The object this study is analyze subcortical anatomy region when infiltrated by and compare it with normal in nontumoral hemispheres. METHODS Ten postmortem human hemispheres were dissected, isolation inferior fronto-occipital fasciculus (IFOF) uncinate fasciculus. Probabilistic diffusion tensor imaging (DTI)...
OBJECTIVE Most knowledge regarding the anatomical organization of multilingualism is based on aphasiology and functional imaging studies. However, results have still to be validated by gold standard approach, namely electrical stimulation mapping (ESM) during awake neurosurgical procedures. In this ESM study authors describe language representation in a highly specific group 13 multilingual individuals, focusing how age acquisition may influence cortical language. METHODS Thirteen patients...
Contralateral clipping of middle cerebral artery (MCA) aneurysms seems dangerous and ill advised but could become an important technique because the prevalence MCA aneurysms, limitations endovascular therapy, increasing interest in less invasive techniques.To define patient selection, surgical technique, results with contralateral aneurysm clipping.Forty-two patients bilateral were treated either 1 stage a single craniotomy (group 1, 11 patients) or 2 stages 2, 31 patients). Surgical...
Object Olfactory dysfunction has an important impact on quality of life. In patients with subarachnoid hemorrhage (SAH), anosmia mainly been reported after surgery for aneurysms the anterior communicating artery (ACoA). The authors studied whether and how frequently ACoA present smell identification deficits in 2 treatment groups (endovascular surgical treatment). Methods A prospective study was conducted SAH caused by ruptured ACoAs who had a Glasgow Outcome Scale score 1 or 2, comparison...
