Abstract
BACKGROUND Decompressive craniectomy is a surgical way to treat intracranial hypertension, by removing a large flap of skull bone. METHOD We report the case of a 48 years old right-handed man presenting an acute ischaemic stroke of all the right sylvian artery area, with rapid clinic deterioration then coma. Severe intracranial hypertension was confirmed by transcranial Doppler. In emergency, we decided to perform a right-side decompressive craniectomy. CONCLUSION Six months later, he is in rehabilitation with "only" a left hemiplegia and a very good relational life. His modified Rankin score is 3. Decompressive craniectomy saved this patient's life, that is why we think this surgical technique must be explained and mastered.

Abstract
Traumatic brain injury according to the World Health Organization estimates that by 2020 will be the third leading cause of morbidity and mortality worldwide. Intracranial hypertension refractory to medical management is the cause of increased mortality in neurotrauma. There are various measures to control intracranial hypertension, including surgical. Decompressive craniectomy has been routinely used to treat intracranial hypertension secondary to cerebral infarction, subarachnoid hemorrhage, intracerebral hemorrhage and trauma. We review the literature to describe the mechanisms, types and indications for this procedure.

Abstract
BACKGROUND Hydrocephalus and intracranial hypertension are rare signs of spinal tumors when presenting in isolation, particularly with benign tumors. CASE DESCRIPTION Herein reported is a case of a 53-year-old woman who presented with headache, blurry vision, communicating hydrocephalus, and intracranial hypertension. No primary intracranial pathology was identified, and there were no clinical signs or symptoms of intraspinal pathology. Lumbar puncture revealed elevated opening pressure, cerebrospinal fluid protein, and suspected tumor cells in the cerebrospinal fluid, thus prompting spinal imaging. A primary lumbar schwannoma was subsequently determined to underlie her symptoms, which resolved with tumor resection. CONCLUSIONS Clinical suspicion of spinal pathology should be maintained in patients with unexplained intracranial hypertension, even in the absence of localizing signs of spinal pathology.

Abstract
Patients with complex, multisutural, and syndromic craniosynostosis (CSO) frequently exhibit intracranial hypertension. The intracranial hypertension cannot be entirely attributed to the craniocephalic disproportion with calvarial restriction because cranial vault expansion has not consistently alleviated elevated intracranial pressure. Evidence has most strongly supported a multifactorial interaction, including venous hypertension along with other pathogenic processes. Patients with CSO exhibit marked venous anomalies, including stenosis of the jugular-sigmoid complex, transverse sinuses, and extensive transosseous venous collaterals. These abnormal intracranial-extracranial occipital venous collaterals might represent anomalous development, with persistence and subsequent enlargement of channels normally present in the fetus, either as a primary defect or as nonregression in response to failure of the development of the jugular-sigmoid complexes. It has been suggested by some investigators that venous hypertension in patients with CSO could be treated directly via jugular foraminoplasty, venous stenting, or jugular venous bypass, although these options are not in common clinical practice. Obstructive sleep apnea, occurring as a consequence of midface hypoplasia, can also contribute to intracranial hypertension in patients with syndromic CSO. Thus, correction of facial deformities, as well as posterior fossa decompression, could also play important roles in the treatment of intracranial hypertension. Determining the precise mechanistic underpinnings underlying intracranial hypertension in any given patient with CSO requires individualized evaluation and management.

Abstract
OBJECTIVE Women taking combined hormonal contraceptives (CHCs) are generally considered to be at low risk for cerebral venous thrombosis (CVT). When it does occur, however, intensive care and neurosurgical management may, in rare cases, be needed for the control of elevated intracranial pressure (ICP). The use of nonsurgical strategies such as barbiturate coma and induced hypothermia has never been reported in this context. The objective of this study is to determine predictive factors for invasive or surgical ICP treatment and the potential complications of nonsurgical strategies in this population. METHODS The authors conducted a 2-center, retrospective chart review of 168 cases of CVT in women between 2000 and 2012. Eligible patients were classified as having had a mild or a severe clinical course, the latter category including all patients who underwent invasive or surgical ICP treatment and all who had an unfavorable outcome (modified Rankin Scale score ≥ 3 or Glasgow Outcome Scale score ≤ 3). The Mann-Whitney U-test was used for continuous parameters and Fisher's exact test for categorical parameters, and odds ratios were calculated with statistical significance set at p ≤ 0.05. RESULTS Of the 168 patients, 57 (age range 16-49 years) were determined to be eligible for the study. Six patients (10.5%) required invasive or surgical ICP treatment. Three patients (5.3%) developed refractory ICP > 30 mm Hg despite early surgical decompression; 2 of them (3.5%) were treated with barbiturate coma and induced hypothermia, with documented infectious, thromboembolic, and hemorrhagic complications. Coma on admission, thrombosis of the deep venous system with consecutive hydrocephalus, intraventricular hemorrhage, and hemorrhagic venous infarction were associated with a higher frequency of surgical intervention. Coma, quadriparesis on admission, and hydrocephalus were more commonly seen among women with unfavorable outcomes. Thrombosis of the transverse sinus was less common in patients with an unfavorable outcome, with similar distribution in patients needing invasive or surgical ICP treatment. CONCLUSIONS The need for invasive or surgical ICP treatment in women taking CHCs who have CVT is partly predictable on the basis of the clinical and radiological findings on admission. The use of nonsurgical treatments for refractory ICP, such as barbiturate coma and induced hypothermia, is associated with systemic infectious and hematological complications and may worsen morbidity in this patient population. The significance of these factors should be studied in larger multicenter cohorts.

Abstract
RATIONALE Primary central nervous system lymphoma (PCNSL) is a rare disease. Studies of PCNSL in patients with rheumatic diseases are lacking. Neither clinical symptoms nor radiographic manifestation is specific to PCNSL. Therefore, it could be misdiagnosed with other diseases such as brain tumors. Chemotherapy is the primary treatment for PCNSL, while the role of surgery remains controversial. PATIENT CONCERNS We reported a 39-year-old woman with systemic lupus erythematosus (SLE) developed PCNSL after 15-year treatment with multiple immunosuppressants. DIAGNOSES Cranial magnetic resonance imaging (MRI) showed multi-focal lesions with ring-like enhancement post-contrast in the right hemisphere, which mimicked glioma radiographically. Owing to the severe symptoms of intracranial hypertension, gross tumor resection was performed. Pathological exam showed perivascular infiltration of atypical lymphoid cells with CD20 and Epstein-Barr virus (EBV) -encoded RNA (EREB) positive. The patient was diagnosed with diffuse large B-cell lymphoma (DLBCL). INTERVENTIONS The patient received six cycles of chemotherapy and autologous stem cell transplantation (ASCT) subsequently. OUTCOMES The patient remained complete remission until this article was written. LESSONS PCNSL in immunocompromised hosts may present heterogeneous contrast enhancement, which should be differentiated from other diseases especially high-grade glioma.

Abstract
CONTEXT Pseudotumor cerebri occurs when there is an increase in intracranial pressure without an underlying cause, usually leading to loss of vision. It is most commonly observed in obese women of child-bearing age. CASE REPORT A 46-year-old woman presented at our service with idiopathic intracranial hypertension that had been diagnosed two years earlier, which had led to chronic refractory headache and an estimated 30% loss of visual acuity, associated with bilateral papilledema. She presented partial improvement of the headache with acetazolamide, but the visual loss persisted. Her intracranial pressure was 34 cmH2O. She presented a body mass index of 39.5 kg/m2, also associated with high blood pressure. Computed tomography of the cranium with endovenous contrast did not show any abnormalities. She underwent Roux-en-Y gastric bypass with uneventful postoperative evolution. One month following surgery, she presented a 24% excess weight loss. An ophthalmological examination revealed absence of visual loss and remission of the papilledema. There were no new episodes of headache following the surgery. There was also complete resolution of high blood pressure. The intracranial pressure decreased to 24 cmH2O, six months after the surgery. CONCLUSION Although the condition is usually associated with obesity, there are few reports of bariatric surgery among individuals with pseudotumor cerebri. In cases studied previously, there was high prevalence of resolution or improvement of the disease following bariatric surgery. There is no consensus regarding which technique is preferable. Thus, further research is necessary in order to establish a specific algorithm.

Abstract
After traumatic brain injury, decompressive craniectomy (DC) is a second-tier, late therapy for refractory intracranial hypertension. We hypothesize that early DC, based on CT evidence of intracranial hypertension, improves intracranial pressure (ICP) and cerebral perfusion pressure (CPP). From September 2008 to January 2015, 286 traumatic brain injury patients requiring invasive ICP monitoring at a single Level I trauma center were reviewed. DC and non-DC patients were propensity score matched 1:1, based on demographics, hemodynamics, injury severity score (ISS), Glasgow Coma Scale (GCS), transfusion requirements, and need for vasopressor therapy. Data are presented as M ± SD or median (IQR) and compared at P ≤ 0.05. The study population was 42 ± 17 years, 84 per cent male, ISS = 29 ± 11, GCS = 6(5), length of stay (LOS) = 32(40) days, and 28 per cent mortality. There were 116/286 (41%) DC, of which 105/116 (91%) were performed at the time of ICP placement. For 50 DC propensity matched to 50 non-DC patients, the midline shift was 7(11) versus 0(5) mm (P < 0.001), abnormal ICP (hours > 20 mm Hg) was 1(10) versus 8(16) (P = 0.017), abnormal CPP (hours < 60 mm Hg) was 0(6) versus 4(9) (P = 0.008), daily minimum CPP (mm Hg) was 67(13) versus 62(17) (P = 0.010), and daily maximum ICP (mm Hg) was 18(9) versus 22(11) (P < 0.001). However, LOS [33(37) versus 25(34) days], mortality (24 versus 30%), and Glasgow Outcome Score Extended [3.0(3.0) versus 3.0(4.0)] did not improve significantly. Early DC for CT evidence of intracranial hypertension decreased abnormal ICP and CPP time and improved ICP and CPP thresholds, but had no obvious effect on the outcome.

Abstract
Introduction Insertion of external ventricular drain (EVD) is a widely accepted, routinely performed procedure for treatment of hydrocephalus and raised intracranial pressure. The purpose of this study was to investigate whether a surgeon's experience affects the associated complication rate. Methods This retrospective study included all adult patients undergoing EVD insertion at a single centre between July 2013 and June 2015. Medical records were retrieved to obtain details on patient demographics, surgical indication, risk factors for infection and use of anticoagulants or antiplatelets. Surgeon experience, operative time, intraoperative antibiotic prophylaxis, need for revision surgery and EVD associated infection were examined. Information on catheter tip position and radiological evidence of intracranial haemorrhage was obtained from postoperative imaging. Results A total of 89 patients were included in the study. The overall infection, haemorrhage and revision rates were 4.8%, 7.8% and 13.0% respectively, with no significant difference among surgeons of different experience. The mean operating time for patients who developed an infection was 22 minutes while for those without an infection, it was 33 minutes (p=0.474). Anticoagulation/antiplatelet use did not appear to increase the rate of haemorrhage. The infection rate did not correlate with known risk factors (eg diabetes and steroids), operation start time (daytime vs out of hours) or duration of surgery although intraoperative (single dose) antibiotic prophylaxis seemed to reduce the infection rate. There was also a correlation between longer duration of catheterisation and increased risk of infection. Conclusions This is the first study demonstrating there is no significant difference in complication rates between surgeons of different experience. EVD insertion is a core neurosurgical skill and junior trainees should be trained to perform it.

Abstract
BACKGROUND The current surgical treatment of choice for refractory intracranial hypertension after traumatic brain injury (TBI) is decompressive craniectomy. Despite efficacy in control of intracranial pressure (ICP), its contribution to an improved outcome is debatable. CASE DESCRIPTION We describe a case of refractory intracranial hypertension successfully managed with cisternostomy. The rationale for this surgical technique is discussed, with a focus on the pathophysiologic processes underlying elevated ICP and its improvement after surgery. CONCLUSION Cisternostomy proved to have an immediate effect in controlling ICP and improving brain oxygenation and metabolism.

Abstract
BACKGROUND The close correlation between intracerebral pressure (ICP) and immunologic responses has been well described, but the role of T lymphocytes in this process remains unknown. This study targeted the relationship of circulating T lymphocytes and ICP in patients with intracerebral hemorrhage (ICH). METHODS Between October 2015 and October 2016, consecutive patients age 18-65 years with ICH were enrolled. ICP values were recorded hourly for 5 days, and the screened patients were divided into 2 groups based on ICP: the elevated ICP group (ICP >20 mmHg) and normal ICP group (ICP ≤20 mmHg). Peripheral blood was collected on admission and T lymphocyte subpopulations were analyzed by flow cytometry. Glasgow Coma Scale score on admission and Glasgow Outcome Scale (GOS) score at 30 days after ICH were analyzed. RESULTS A total of 44 patients were enrolled, including 18 patients in the elevated ICP group and 26 in the normal ICP group. Both CD3+ and CD4+ T lymphocyte counts were higher in the elevated ICP group (P = 0.004 and 0.000, respectively). The CD8+ T lymphocyte count was not significantly different between the 2 groups (P = 0.751). There were correlation trends between the maximum ICP value and CD3+ lymphocyte count (P = 0.003), CD4+ T lymphocyte count (P = 0.000), and the CD4+/CD8+ T lymphocyte ratio (P = 0.000). The area under the curve (AUC) of CD4+/CD8+ T lymphocyte ratio was the largest among them (P = 0.011 and 0.033), with a significant cutoff value and good specificity and sensitivity. There was a close correlation between the CD4+/CD8+ T lymphocyte ratio and the 30-day GOS score (P = 0.003, AUC = 0.812). CONCLUSIONS The CD4+/CD8+ T lymphocyte ratio may be a valuable indicator for predicting postoperative ICP and the short-term prognosis after ICH.

Abstract
OBJECTIVES To find the correlation between radiologically proven improvement in cerebral hemodynamics with clinical improvement in patients undergoing cranioplasty. MATERIAL AND METHODS The study is a prospective observational study of 10 cases, in M S Ramaiah Institute of Neurosciences, involving patients treated by a decompressive craniectomy for intractable intra cranial hypertension either due to trauma or stroke and afterwards underwent cranioplasty. RESULTS Of the 10 patients, 70% patients showing significant improvement in motor functions on Barthel index scale, 60% patients showed improvement in speech, mean duration from date of decompressive craniectomy to cranioplasty being 122.4days. Cerebral perfusion was remarkably better after cranioplasty, as demonstrated decrease in the Pulsatility index on the ipsilateral side of decompression on Trans cranial Doppler (<0.73 mean). This data also favored improved cerebral blood flow and permeability on the CT perfusion with increase in cerebral blood flow (CBF), Cerebral Blood Volume (CBV) and decrease in Time to Peak (TTP) and a positive outcome when correlated with Barthel index with P-values of 0.093, 0.017 and 0.001 respectively. CONCLUSION Cranioplasty influences the cerebral hemodynamics after cranioplasty and has a positive correlation on the functional outcome and cerebral blood flow in the MCA territory.

Abstract
OBJECTIVE To study efficacy and safety of prophylactic levetiracetam (LEV) administration in adults undergoing cranioplasty. METHODS We prospectively enrolled and randomly divided 200 adults undergoing cranioplasty into 2 groups: LEV (prophylactic LEV for 24 weeks) and control (no prophylactic antiepileptic drugs). Demographic and clinical characteristics; occurrence of postoperative seizure; changes in IQ, memory quotient, and activities of daily living scores; and postoperative side effects during hospital stay were analyzed at 2-, 24-, and 48-week follow-up visits. RESULTS Significant differences were found between groups in both early-stage seizures in the initial 2 weeks and late-stage seizures in the 3-24 weeks after cranioplasty (P < 0.05). Postoperative seizures occurred in 17.0% in the control group and 4.1% in the LEV group 48 weeks after cranioplasty, which was found to be significant (P = 0.0020). Patients with abnormal preoperative or postoperative electroencephalography (EEG) with spikes or sharp waves presented with an increased number of postoperative seizures compared with patients with normal EEG readings at 48 weeks. Significant differences were found between patients with postoperative seizures and patients without postoperative seizures in regard to changes in IQ, memory quotient, activities of daily living, and patient satisfaction scores (P < 0.01). No significant difference was found in side effects between the 2 groups. CONCLUSIONS Postoperative seizure is a common complication of cranioplasty, especially in patients with preoperative or postoperative abnormal EEG with spikes or sharp waves. Prophylactic LEV administration significantly reduced postcranioplasty seizures during LEV usage and had few side effects.

Abstract
OBJECTIVE To characterize shifts from the 1960s to the first decade in the 21st century as to diagnostics, case-mix, and surgical management of pediatric patients undergoing permanent CSF diversion procedures. METHODS One hundred and thirty-four patients below 15 years of age were the first time treated with CSF shunt or ETV for hydrocephalus or idiopathic intracranial hypertension (IIH) in 2009-2013. This represents our current practice. Our previously reported cohorts of shunted children 1967-1970 (n = 128) and 1985-1988 (n = 138) served as backgrounds for comparison. RESULTS In the 1960s, ventriculography and head circumference measurements were the main diagnostic tools; ventriculoatrial shunt was the preferred procedure (94 %), neural tube defect (NTD) was the leading etiology (33 %), and overall 2-year survival rate was 76 % (non-tumor survival 84 %). In the 1980s, computerized tomography (CT) was the preferred diagnostic imaging tool; ventriculoperitoneal shunt (VPS) had become standard (91 %), the proportion of NTD children declined to 17 %, and the 2-year survival rate was 91 % (non-tumor survival 95 %). Hydrocephalus caused by intracranial hemorrhage had, on the other hand, increased from 7 to 19 %. In the years 2009-2013, when MRI and endoscopic third ventriculocisternostomy (ETV) were matured technologies, 73 % underwent VPS, and 23 % ETV as their initial surgical procedure. The most prevalent etiology was CNS tumor (31 %). The proportion of NTD patients was yet again halved to 8 %, while intracranial hemorrhage was also reduced to 12 %. In this last period, six children were treated with VPS for Idiopathic Intracranial Hypertension (IIH) due to unsatisfactory response to medical treatment. They all had headache, papilledema, and visual disturbances and responded favorably to treatment. The 2 years of survival was 92 % (non-tumor survival 99 %). In contrast to the previous periods, there was no early shunt related mortality (2 years). Aqueductal stenosis was a small but distinctive group in all cohorts with 5, 6 and 3 % respectively. CONCLUSIONS The case-mix in pediatric patients treated with permanent CSF diversion has changed over the last half-century. With the higher proportion of children with CNS tumor patients and inclusion of the IIH children, the median age at initial surgery has shifted substantially from 3.2 to 14 months. Between the 1960s and the current cohort, 2 years of all-cause mortality fell from 24 to 8 %. Prolonged asymptomatic periods, extending 15 years, were relatively common. Nevertheless, 18 patients experienced shunt failure more than 15 years after last revision, and first-time shunt failure has been observed 29 years after initial treatment. This underscores the importance of life-long follow-up.

Abstract
BACKGROUND The effect of decompressive craniectomy on clinical outcomes in patients with refractory traumatic intracranial hypertension remains unclear. METHODS From 2004 through 2014, we randomly assigned 408 patients, 10 to 65 years of age, with traumatic brain injury and refractory elevated intracranial pressure (>25 mm Hg) to undergo decompressive craniectomy or receive ongoing medical care. The primary outcome was the rating on the Extended Glasgow Outcome Scale (GOS-E) (an 8-point scale, ranging from death to "upper good recovery" [no injury-related problems]) at 6 months. The primary-outcome measure was analyzed with an ordinal method based on the proportional-odds model. If the model was rejected, that would indicate a significant difference in the GOS-E distribution, and results would be reported descriptively. RESULTS The GOS-E distribution differed between the two groups (P<0.001). The proportional-odds assumption was rejected, and therefore results are reported descriptively. At 6 months, the GOS-E distributions were as follows: death, 26.9% among 201 patients in the surgical group versus 48.9% among 188 patients in the medical group; vegetative state, 8.5% versus 2.1%; lower severe disability (dependent on others for care), 21.9% versus 14.4%; upper severe disability (independent at home), 15.4% versus 8.0%; moderate disability, 23.4% versus 19.7%; and good recovery, 4.0% versus 6.9%. At 12 months, the GOS-E distributions were as follows: death, 30.4% among 194 surgical patients versus 52.0% among 179 medical patients; vegetative state, 6.2% versus 1.7%; lower severe disability, 18.0% versus 14.0%; upper severe disability, 13.4% versus 3.9%; moderate disability, 22.2% versus 20.1%; and good recovery, 9.8% versus 8.4%. Surgical patients had fewer hours than medical patients with intracranial pressure above 25 mm Hg after randomization (median, 5.0 vs. 17.0 hours; P<0.001) but had a higher rate of adverse events (16.3% vs. 9.2%, P=0.03). CONCLUSIONS At 6 months, decompressive craniectomy in patients with traumatic brain injury and refractory intracranial hypertension resulted in lower mortality and higher rates of vegetative state, lower severe disability, and upper severe disability than medical care. The rates of moderate disability and good recovery were similar in the two groups. (Funded by the Medical Research Council and others; RESCUEicp Current Controlled Trials number, ISRCTN66202560 .).

Abstract
OBJECTIVE To verify if the size of the bone flap and the bone window area may have an impact on the outcome of decompressive craniectomy. PATIENTS AND METHODS From February 2012 to February 2014, 42 patients with acute intracranial hypertension were enrolled in this study. We conducted standard craniotomy and decompressive hemicraniectomy on all patients. The intracranial pressure was measured before the hemicraniectomy operation, at the time of bone flap removal, at the time of the incision of the dura mater and 24 hours after the operation. RESULTS Intracranial pressure readings at the time of bone flap removal, incising dura mater and 24 hours postoperation were significantly lower than the pressure measured before the operation. The highest pressure was recorded at the time of the dura mater incision followed by pressure recorded at 24 hours post-operation and at the time of bone flap removal. The lowest pressure was recorded during the preoperative period. Postoperative GOSE and GCS scores were significantly higher than those scores recorded before the operation. A positive correlation between the diameter of the bone disc and the amount of drop in pressure at 24 h post-operation was detected. Also, the bone window area showed a positive correlation with the amount of drop in pressure at 24 h post-operation. CONCLUSIONS The bone flap decompressive craniectomy is safe and effective, and the depressurizing range has a positive correlation with the diameter of the bone disc and the area of the bone window.

Abstract
BACKGROUND Decompressive craniectomy procedures are performed in patients with malignant intracranial hypertension. A bone flap is removed to relieve pressure. Later, a second operation is performed to reconstruct the skull after brain swelling has resolved. This surgical treatment would be improved if it were possible to perform a single operation that decompressed the brain acutely and eliminated the need for a second operation. To design a device and procedure that achieve this objective, it is essential to understand how the brain swells after a craniectomy procedure. METHODS We identified 20 patients with ischemic stroke who underwent a decompressive hemicraniectomy operation. Skull defect morphology and postoperative brain swelling were measured using computed tomography scan data. Additional intracranial volume created by placing a hypothetical cranial plate implant offset from the skull surface by 5 mm was measured for each patient. RESULTS The average craniectomy area and brain herniation volume was 9999 ± 1283 mm2 and 30.48 ± 23.56 mL, respectively. In all patients, the additional volume created by this hypothetical implant exceeded the volume of brain herniation observed. CONCLUSIONS These findings show that a cranial plate with a 5-mm offset accommodates the brain swelling that occurs in this patient population.

Abstract
OBJECTIVE To determine the safety and efficacy of endoscopic optic nerve sheath fenestration (ONSF) for the reversal of papilledema in intracranial venous hypertension. MATERIAL AND METHOD A retrospective chart review was performed on two consecutive patients who underwent endoscopic ONSF. Presenting symptoms, neuro-ophthalmological work-ups, including visual acuity (VA), visual field charting (VF), optical coherence tomography (OCT) and MRI as well as magnetic resonance venography (MRV) were recorded. Cerebrospinal fluid pressure was also measured preoperatively in both individuals. Visual improvement was assessed by comparing with preoperative ophthalmological findings. RESULTS This report is the first endoscopic ONSF study focusing on treatment of papilledema resulting from intracranial venous hypertension (tumor compressing transverse sigmoid junction in the first patient and venous sinus stenosis in the second patient). ONSF was performed on both sides of the first patient and on the right optic nerve of the second patient with showing reduction of papilledema on both eyes. Papilledema was improved in both individuals. Vision improved more in the first patient than in the second whom had pre-existing optic nerve atrophy. CONCLUSION Endoscopic optic nerve sheath fenestration is an effective and safe procedure to revert visual loss or to stabilize vision in patients presenting with visual loss caused by intracranial venous hypertension.

Abstract
A report of intracranial hypertension in unruptured cerebral arteriovenous malformation (AVMs) is presented. A 16-years-old obese female presented with a first episode of acute severe headache and papilledema. Non-contrasted computer tomography scan demonstrated no evidence of hemorrhage or hydrocephalus. The magnetic resonance imaging brain shows the unruptured AVMs at right temporal area. The AVMs was urgently embolized by glue. Headache completely disappeared within two weeks. The papilledemagradually improved within two weeks and completely recovered within six weeks. Patients with unruptured AVMs should undergo early intervention, either by means of surgical excision or embolization, so as to avoid the permanent deficits of optic nerve such as decreased visual acuity and impaired visual field and optic atrophy.

Abstract
Paradoxical herniation (PH) is a life-threatening emergency after decompressive craniectomy. In the current study, we examined patient survival in patients who developed PH after decompressive craniectomy versus those who did not. Risk factors for, and management of, PH were also analyzed. This retrospective analysis included 429 consecutive patients receiving decompressive craniectomy during a period from January 2007 to December 2012. Mortality rate and Glasgow Outcome Scale (GOS) were compared between those who developed PH (n = 13) versus those who did not (n = 416). A stepwise multivariate logistic regression analysis was carried out to examine the risk factors for PH. The overall mortality in the entire sample was 22.8%, with a median follow-up of 6 months. Oddly enough, all 13 patients who developed PH survived beyond 6 months. Glasgow Coma Scale did not differ between the 2 groups upon admission, but GOS was significantly higher in subjects who developed PH. Both the disease type and coma degree were comparable between the 13 PH patients and the remaining 416 patients. In all PH episodes, patients responded to emergency treatments that included intravenous hydration, cerebral spinal fluid drainage discontinuation, and Trendelenburg position. A regression analysis indicated the following independent risk factors for PH: external ventriculostomy, lumbar puncture, and continuous external lumbar drainage. The rate of PH is approximately 3% after decompressive craniectomy. The most intriguing findings of the current study were the 0% mortality in those who developed PH versus 23.6% mortality in those who did not develop PH and significant difference of GOS score at 6-month follow-up between the 2 groups, suggesting that PH after decompressive craniectomy should be managed aggressively. The risk factors for PH include external ventriculostomy, ventriculoperitoneal shunt, lumbar puncture, and continuous external lumbar drainage.

Abstract
Substantiation of the shunt failure diagnosis and subsequent consideration of indications for surgical elimination of the malfunction is a laborious and challenging process. Identification of a malfunction in doubtful cases requires, in addition to standard examinations, extra diagnostic procedures, which may delay making a decision for several weeks to several months. The article describes a case of mechanical CSF shunt malfunction (breakage and failure of a peritoneal catheter in a 7-year-old girl) with intracranial hypertension symptoms, but without typical enlargement of the brain ventricles. According to the medical history, congenital hydrocephalus in the child was accompanied by an inflammatory process of bacterial and viral etiology. The absence of brain ventricle enlargement was shown not to exclude a probability of shunt malfunction. In this case, a specific phenomenon, an intraparenchymatous cerebrospinal fluid "lake" surrounding a ventricular catheter, was observed. Shunting recovery did not lead to a significant reduction in the phenomenon size. Causes underlying this phenomenon require further investigation.

Abstract
INTRODUCTION Idiopathic intracranial hypertension (IIH) is a rare condition that is often managed conservatively. In patients with aggressive progression of the disease surgical options are considered. There are few data on the outcomes of these patients when surgically managed. We describe our experience of surgically managed IIH and the outcomes of these patients, in particular the surgical revision rate and interventions required for resolution of symptoms. METHODS A retrospective review of all patient files coded with benign intracranial hypertension, idiopathic intracranial hypertension or pseudotumour cerebri was undertaken. Files were searched with the date of diagnosis and the date these patients were referred for surgical intervention. The surgical interventions and complications were then documented and note was made of the number of inpatient admissions and days spent in hospital. RESULTS From 2000-2013, 79 patients were identified as patients with IIH that had required surgical intervention; 52 % required further surgical intervention. The average number of surgical interventions was 5.6. For patients requiring further intervention the average number of surgical interventions was 8.6. On average patients with IIH also spent 42 inpatient days in neurosurgical beds, whilst those patients who required further intervention spent 63 days on average in neurosurgical beds. The length of the average individual admission was longer for patients requiring repeated surgical interventions. CONCLUSION Based on our experience, patients that require surgical management of IIH frequently require further surgical interventions to control symptoms and manage complications of CSF diversion surgery. Those that require such further intervention on average will have six further operations and spend significantly longer in hospital. Lumboperitoneal (LP) shunting is an effective first line surgical intervention for 52 % of our patient cohort. This sub-group of patients therefore requires specialist neurosurgical input for this long-term and challenging pathological process.

Abstract
Decompressive craniotomy (DC) in children is a life-saving procedure for the treatment of refractory intracranial hypertension related to traumatic, ischemic and infectious lesions. Different surgical procedures have been proposed including uni or bilateral hemicraniectomy, bi-frontal, bi-temporal, or bi-parietal craniotomies. DC can avoid the cascade of events related to tissue hypoxia, brain perfusion reduction, hypotension and the evolution of brain edema that can be responsible for brain herniation. The monitoring of intracranial pressure (ICP) is very important to take a decision as well as the value of Trans cranial Doppler (TCD). Repeated TCD in the intensive care unit give important information about the decrease of the cerebral perfusion pressure (CPP) and facilitates the decision making. The important question is about how long time we have to wait before to perform the DC. Three conditions can be distinguished: 1) ICP stable and TCD with good parameters: the decision can be postponed; 2) ICP>20 mmHg with good TCD and without clinical signs of deterioration: the decision can be postponed; 3) ICP>20 mmHg with altered CPP and degraded TCD value and clinical signs of brain herniation: the surgical procedure is indicated. The decision of a ventricular drainage can also be discussed but in cases of slit ventricles it is preferable to realize a DC to avoid the problems of multiple taps without finding the ventricular system. In some very specific situations, DC has to be contraindicated. The first one is a prolonged cardiopulmonary arrest with a no-flow longer than 15 minutes and irreversible lesions on the TCD or on the CT-scan. The second most common situation is a patient with GCS of 3 on admission associated with bilaterally fixed dilated pupils. In this case TCD is very useful to document the decrease or the absence of diastolic flux that indicates a very poor cerebral perfusion. In case of severe polytraumatism with multiorgan failure, especially in very severe hemorrhagic shock with incontrollable coagulopathy, the realization of DC is definitely hazardous with y a high risk of cardiac arrest during the surgical procedure. The decision to realize a hemicraniectomy or a bi-frontal craniotomy is related to the presence or not of associated traumatic lesions as hemorrhagic contusions or a sub-dural or extradural hematoma. In cases of diffuse cerebral edema the bi-frontal bone flap is indicated. In all cases a closure of the dura mater with a large dural patch has to be performed avoiding compression of the nervous system. Our results showed a mortality rate of 18%. Eighty percent of the survivors have a good quality of life but only 43% in a scholar age could attend a normal program. Patients treated with DC need a long follow-up and an important rehabilitation program to improve their quality of life. Our report shows that DC in children is effective to control the post-traumatic intracranial hypertension but a long follow-up is recommended to access the sequels and quality of life of these patients.
