Abstract
PURPOSE The study aimed to investigate factors associated with in-hospital mortality in children diagnosed with tuberculous meningitis (TBM) hydrocephalus and HIV co-infection undergoing cerebrospinal fluid diversion procedures and their complications. METHODS Data were collected retrospectively and prospectively between 2007 and 2022. Data collected included demographics, clinical characteristics, antiretroviral therapy (ART) status, biochemistry results, CD4 count, radiology findings, CSF diversion procedures (and complications), length of hospital stay (LOHS), and in-hospital mortality. RESULTS Thirty-one children were included, with a mean age of 6.7 ± 5.3 years and 67.7% males. Median admission Glasgow Coma Scale (GCS) was 11 (IQR 9-15). Hypertonia (64.5%) and seizures (51.6%) were frequently observed clinical characteristics. Sixty-one percent of children were on ART. Cerebral infarcts and extra-meningeal TB were diagnosed in 64.5% and 19.3% of cases, respectively. The median CD4 count was 151 (IQR 70-732) cells/µL. Surgical procedures included ventriculoperitoneal shunt (VPS) in 26 cases and endoscopic third ventriculostomy (ETV) in five children. VPS complication rate was 27%. No complications were reported for ETV. Median LOHS was 7 days (IQR 4-21). Eleven children (35.5%) died during admission. Factors associated with mortality included GCS (p = 0.032), infarcts (p = 0.004), extra-meningeal TB (p = 0.003), VPS infection (p = 0.018), low CD4 count (p = 0.009), and hyponatremia (p = 0.002). No statistically significant factors were associated with VPS complications. CONCLUSION TBM hydrocephalus in HIV-infected children carries a high mortality. Clinicians in high-prevalence settings should have a high suspicion index and institute early treatment.

The Outcome of Surgical Intervention (Ventriculoperitoneal Shunt and Endoscopic Third Ventriculostomy) in Patients With Hydrocephalus Secondary to Tuberculous Meningitis: A Systematic Review. Cureus 2022; 14:e25317.

Abstract
The objective of this study is to analyze the outcome of the safety and efficiency of the surgical interventions (ventriculoperitoneal shunt [VPS] and endoscopic third ventriculostomy [ETV]) in patients with hydrocephalus due to tuberculous (TB) meningitis. A systematic literature search has been conducted using PubMed, Google Scholar, PMC, and ScienceDirect databases from 2001 to 2022 April. A total of 16 studies have been included, irrespective of their design. These studies include patients diagnosed with hydrocephalus secondary to TB meningitis (TBM) treated with VPS or ETV. A systematic review was conducted to determine the efficiency of surgical procedures based on the outcomes and complications associated with these procedures. A total of 2207 patients (aged one month to 68 years) have been included in this study, out of which 1723 underwent VPS and 484 underwent ETV. The overall success rate in the VPS group varied from 21.1% to 77.5%. The overall success rate in the ETV group ranged from 41.1% to 77%. The overall complications rate in the VPS group varied from 10% to 43.8%, and the complications rate in the ETV group varied from 3.8% to 22.5%. After ruling out the significant differences in the average percentages of outcomes and complications followed by VPS and ETV, ETV is suggested in patients with chronic phases of illness because the chances of ETV failure are high during the initial stage. The uncertainty of the ETV gradually decreases over time. To attain favourable long-term outcomes with ETV in patients with TBM hydrocephalus (TBMH), ETV should be performed after chemotherapy, anti-tubercular treatment, and steroids. In addition, ETV is considered beneficial over VP shunt as associated long-term complications are significantly less compared to VP shunt. In contrast, VP shunt is suggested as a modified Vellore grading which shows a more favourable outcome in patients with acute illness than ETV.

J Pediatr Neurosci 2021; 16:106-112. [PMID: 35018177 PMCID: PMC8706600 DOI: 10.4103/jpn.jpn_286_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Revised: 10/27/2020] [Accepted: 02/11/2021] [Indexed: 11/04/2022] Open
Abstract
Objective Hydrocephalus is one of the most common complications of tuberculous meningitis. Various cerebrospinal fluid diversion procedures, endoscopic third ventriculostomy (ETV) and shunt surgery, are performed for the management of the hydrocephalus associated with tuberculous bacterial meningitis (TBM). There is decreased clarity on the type of procedure to be done. So, this study aims at generating knowledge to understand the conditions in which either of the two procedures, ETV and shunt surgery, is a better option and to develop good practice guidelines for the treatment of tubercular meningitis hydrocephalus (TBMH). Materials and Methods A systematic search of literature was performed by using PubMed and Cochrane Central Register of Controlled Trials (CENTRAL) for articles published from January 2001 to April 2020. A total of 15 studies were included irrespective of their design and having diagnosis with TBMH treated with ventriculoperitoneal shunt surgery (VPS) or ETV. Then, a systemic review was done regarding outcomes, complications, and recommendations made in different studies. Results The total number of patients diagnosed with TBMH was 603; among them, 348 patients had VPS and 255 patients had ETV. In the VPS group, the patient's good outcome varied from 25% to 68% and complication rate ranged from 10% to 43.8%. The average percentage of good outcome in the VPS group was 51.8%. In the ETV group, the patient's good outcome varied from 41% to 77% and complication rate ranged from 10% to 23.5%. The average percentage of good outcome in the ETV group was 68%. There was a significant difference in the average percentage of good outcome in the ETV versus the VPS shunt group (P-value was 0.008). Conclusion There was a significant difference in the average percentage of good outcome after ETV than VPS, and complication rate was also slightly lower after ETV than VPS during the chronic phase of illness. So during the acute phase of illness VPS placement is preferred whereas in the chronic burnout phase ETV is preferred because poor anatomy leads to more complications with ETV during the acute phase of the disease.

Neurosurg Rev 2020; 44:2201-2209.

Abstract
Because ventriculoperitoneal shunt (VPS) insertion for patients with hydrocephalus from tuberculous meningitis (TBM) can be complicated by shunt infection and malfunction, endoscopic third ventriculostomy (ETV) has been proposed as an alternative. The aim of this review was to determine the success, technical failure, and complication rates of ETV in TBM in a meta-analysis and determine which factors are predictive of outcome. The PubMed, Scopus, and CENTRAL databases were searched from inception to April 2020 for case series, cohort studies, or randomized controlled trials reporting success, technical failure, or complication rates. For studies with individual patient data available, logistic regression analysis was done to determine whether age, sex, clinical grade, and type of hydrocephalus on imaging was predictive of outcome. Eight studies with a total of 174 patients were included in the review. Using random-effects modeling, the pooled estimate of success rate was 59% (95% CI 50-68%), with low heterogeneity (I2 = 30%). The technical failure and complication rates were 5% and 15%, respectively, but these variables had moderate heterogeneity. In 36 patients with individual patient data, a non-communicating type of hydrocephalus on imaging was associated with an odds ratio of 5.90 (95% CI 1.1-32.9, p = 0.043) for success. In summary, ETV for TBM had a pooled success rate of 59%, technical failure rate of 5%, and complication rate of 15%. An imaging finding of non-communicating hydrocephalus was associated with increased success. High-quality randomized, prospective studies using VPS insertion as control are needed to further define the role of ETV in TBM.

Abstract
The assessment and management of tuberculous meningitis (TBM) is often complex, yet no standardised approach exists, and evidence for the clinical care of patients, including those with critical illness, is limited. The roles of proformas and checklists are increasing in medicine; proformas provide a framework for a thorough approach to patient care, whereas checklists offer a priority-based approach that may be applied to deteriorating patients in time-critical situations. We aimed to develop a comprehensive assessment proforma and an accompanying 'priorities' checklist for patients with TBM, with the overriding goal being to improve patient outcomes. The proforma outlines what should be asked, checked, or tested at initial evaluation and daily inpatient review to assist supportive clinical care for patients, with an adapted list for patients in critical care. It is accompanied by a supporting document describing why these points are relevant to TBM. Our priorities checklist offers a useful and easy reminder of important issues to review during a time-critical period of acute patient deterioration. The benefit of these documents to patient outcomes would require investigation; however, we hope they will promote standardisation of patient assessment and care, particularly of critically unwell individuals, in whom morbidity and mortality remains unacceptably high.

Abstract
The two main manifestations of brain tuberculosis that require surgery are hydrocephalus associated with tuberculous meningitis (TBMH) and brain tuberculomas. TBMH most often responds to medical therapy but surgery is required promptly for those who fail medical therapy. Both ventriculoperitoneal (VP) shunt and endoscopic third ventriculostomy (ETV) are valid options although the latter is more often successful in patients with chronic hydrocephalus than in those with acute meningitis. Patients with TBMH are more prone to complications following VP shunt than other patients. The outcome of these patients is determined by the Vellore grade (I to IV) of the patients prior to surgery with those in good grades (I and II) having a better outcome and those in the worst grade (IV) having a high mortality in excess of 80 %. Patients with brain tuberculomas present clinically with features of a brain mass, indistinguishable clinically from other pathologies. CT and MR features might provide a probable diagnosis of a tuberculoma but most often a histological diagnosis is desirable. Empiric medical therapy is reserved for a small number of patients. Although the treatment of brain tuberculomas is essentially medical, surgery is required when the diagnosis is in doubt, to reduce raised intracranial pressure or local mass effect and to obtain tissue for culture and sensitivity studies. Stereotactic biopsy, stereotactic craniotomy and excision of superficial small tuberculomas and microsurgery are all procedures used to manage brain tuberculomas. The outcome in patients with brain tuberculomas is good if the tuberculous bacillus is sensitive to the anti-tuberculous therapy. The duration of therapy is debated but we suggest at least 18 months of combination therapy with three or four anti-tuberculous drugs and continue the therapy till the tuberculoma has resolved on neuro-imaging.

Abstract
Hydrocephalus is a very common disease in developing countries. Congenital aqueductal obstruction and post-inflammatory hydrocephalus come on the top of the list of causes of hydrocephalus. Till the recent introduction of cranial endoscopy and despite their frequent complications, shunts were considered as the mainstream treatment for this disease. Endoscopic third ventriculostomy (ETV), especially for obstructive hydrocephalus, introduced a new era of treatment that is free of lifetime shunt dependency. This study was done to assess the efficacy of ETV for treating post-inflammatory hydrocephalus in a unique group of patients thus preventing—if possible—the lifetime shunt dependency and suffering. ETV was tried as a first-line therapy in 35 children (23 males and 12 females) with hydrocephalus proved to be secondary to intracranial infection. Mean age was 9.2 months (4-15). Twenty-four patients (68.6%) were below the age of 6 months while 11 patients (31.4%) were above 6 months. Twenty-five patients (71.4%) had a head circumference of 3 cm and 10 patients (28.6%) had a 5 cm or more increase in the head circumference above the 95th percentile. All the patients included were followed postoperatively with regular clinical, computerized tomography (CT), and magnetic resonance imaging (MRI) examinations as well as cerebrospinal fluid (CSF) analysis and culture. The overall success of ETV was 55.9% (19/34). Nine (81.9%) out of the 11 patients that were endoscopically documented to have aqueductal obstruction showed improvement. While out of the 23 patients with patent aqueduct, only 10 patients (43.4%) had improved. Procedure-related complications were not encountered. CSF leakage from the surgical wound occurred in three patients and mild CSF infection occurred in one patient. ETV is a simple, safe, and effective method in treating not only obstructive hydrocephalus due to non-inflammatory etiology, but also post-inflammatory hydrocephalus especially when the aqueduct is obstructed. An overall 50% improvement in our study and even more in other series encourage the trial of getting rid of the lifetime shunt complications and suffering.

Abstract
OBJECTIVE This study aims at generating knowledge to understand the conditions in which either of the two procedures (endoscopic third ventriculostomy (ETV) and shunt) are better options and to develop good practice guidelines for the treatment of tubercular meningitis (TBM) hydrocephalus. METHODS This study was conducted on 48 patients in pediatric age group (less than or equal to 18 years) of TBM hydrocephalus. The patients were randomized to one of the cerebrospinal fluid diversion procedures (ETV or shunt). The two procedures were compared for their outcome, both radiologically and clinically. RESULTS Twenty-four cases underwent shunt, out of which 13 (68%) cases were successful. Twelve (70.3%) cases belonged to grade 3, while one case was of grade 1. In ETV group, 10 (42%) cases had a successful outcome, out of which 7 (38.8%) cases were in grade 3, while 1 case each belonged to grades 1, 2, and 4. Incidence of ETV failure was more in younger age group, i.e., <2 years (n = 7), while no such correlation with age was found in shunt cases. CONCLUSION Though with the present study it looks like that the relative risk of ETV failure is higher than that for shunt, but the risk becomes progressively lower with time. Therefore, if patients survive the early high-risk period, they could experience a long-term survival advantage devoid of life-long shunt-related complications. Though for definitive comparison, a long-term study is needed.

Abstract
Tuberculous meningitis is especially common in young children and people with untreated HIV infection, and it kills or disables roughly half of everyone affected. Childhood disease can be prevented by vaccination and by giving prophylactic isoniazid to children exposed to infectious adults, although improvements in worldwide tuberculosis control would lead to more effective prevention. Diagnosis is difficult because clinical features are non-specific and laboratory tests are insensitive, and treatment delay is the strongest risk factor for death. Large doses of rifampicin and fluoroquinolones might improve outcome, and the beneficial effect of adjunctive corticosteroids on survival might be augmented by aspirin and could be predicted by screening for a polymorphism in LTA4H, which encodes an enzyme involved in eicosanoid synthesis. However, these advances are insufficient in the face of drug-resistant tuberculosis and HIV co-infection. Many questions remain about the best approaches to prevent, diagnose, and treat tuberculous meningitis, and there are still too few answers.

Abstract
BACKGROUND Hydrocephalus of tubercular origin is one of the most dreaded and difficult to manage complications of brain tuberculosis. Traditionally, the management has been ventriculoperitoneal shunting, but in recent years emerging interest is in endoscopic ventriculostomy. In this article, we discuss the management protocol of hydrocephalus in various stages of disease. METHODS A total of 424 cases of tubercular origin hydrocephalus were managed between years 2000 and 2009. Initially the cases were managed by ventriculoperitoneal shunting, which was followed by use of endoscopic third ventriculostomy. Drug-resistant cases were also encountered and managed according to drug sensitivity. RESULTS The results provided through evaluation of retrospective data showed a high mortality in cases of hydrocephalus of acute origin if endoscopic third ventriculostomy was performed. The cerebrospinal fluid protein level and neurological status of the patient determined the success or failure of the procedure. For better management, patients were divided into six groups and their management underlined. CONCLUSION The cases of tubercular meningitis with aqueductal stenosis presenting in early stages should be given a trial of endoscopic third ventriculostomy where chronic burnt-out cases or cases with communicating hydrocephalus should be managed by ventriculoperitoneal shunting.

Abstract
OBJECTIVE The role of Ommaya reservoir implantation in children with tuberculous meningitis hydrocephalus (TBMH) has been seldomly reported. Therefore, we performed this study to determine the role of the Ommaya reservoir in the treatment of children with TBMH. METHODS We retrospectively analyzed the effects of Ommaya reservoir implantation in 12 children with TBMH. Intracapsular puncture of the reservoir was performed for draining the cerebrospinal fluid and the TBM was treated by intraventricular injection of isoniazid. RESULTS The ideal treatment outcome was observed in nine (75 %) of the 12 children; two (16.7 %) children developed serious disabilities and one of them (8.3 %) eventually died. The treatment method was effective for all six (100 %) children with Palur grade II TBM but showed no effect in three (50 %) children with grade III and IV TBM. The number of leukocytes in the cerebrospinal fluid decreased to 20 × 10(6)/L (75 %) within 2 weeks after implantation of the reservoirs. Finally, the Ommaya reservoirs in eight children were removed but were retained in four children. Four children had to undergo ventriculoperitoneal shunt. CONCLUSION Ommaya reservoir implantation has been shown to be effective in treating children with TBMH. This method may be largely suitable for children with early grade II TBM or partly in children with grade III TBM who have mild or moderate hydrocephalus that can alleviate after short-term treatment. Thus, a good proportion of children who undergo Ommaya reservoir implantation can avoid ventriculoperitoneal shunt surgery.

Abstract
PURPOSE The purpose of this paper was to study the feasibility of endoscopic third ventriculostomy (ETV) as a treatment modality in patients with hydrocephalus of tubercular origin. MATERIALS AND METHODS Literature on ETV in hydrocephalus of tubercular origin has been reviewed, and we have gathered experiences of neurosurgeons from various institutions in our country practicing ETV. RESULTS Hydrocephalus, a common complication of tubercular meningitis, may be of communicating type or of obstructive variety. The communicating type is treated by medical therapy in 70-92% cases, whereas the obstructive type requires surgical intervention. The outcome of surgery depends upon gradation of disease. Shunting however has been a nightmare for neurosurgeons treating such patients (Smyth et al., Pediatr Neurosurg 39: 258-263, 2003). The shunts tend to get blocked with debris. Having found ETV as a successful modality of treatment in obstructive hydrocephalus of other etiology, neurosurgeons have attempted it in hydrocephalus of tubercular origin. Though various authors have had a success rate of 65-68%, failure has been quite high in acute cases due to thickening of the floor of third ventricle and distorted anatomy. The success rate is higher in chronic and burnt out cases. CONCLUSION Tubercular meningitic hydrocephalus is difficult to treat endoscopically as compared with other forms of meningitic hydrocephalus and requires adequate expertise and experience, especially in acute cases. Therefore, one would be justified in avoiding the use of ETV in acute cases and wait till patient presents with a failed shunt. Use of ETV in subacute and chronic cases seems to be justified as the first line of treatment.

Abstract
Tuberculous meningitis (TBM) is the most lethal form of tuberculosis; mortality is high and survivors are often left neurologically disabled. Several factors contribute to this poor outcome, including cerebrovascular involvement with ensuing brain ischemia, hydrocephalus and raised intracranial pressure, direct parenchymal injury, hyponatremia, and seizures. However, there is little standardisation of management with respect to these aspects of care across different centers, largely because the evidence base for much of the supportive treatment of patients with TBM is poor, leading to substantial differences in management protocols. This review emphasizes some of the uncertainties and controversies pertinent to the surgical treatment of hydrocephalus in TBM and the medical supportive management of the patient during the acute phase of the illness, with the aims of raising awareness and stimulating debate. The focus is on the management of hyponatremia, cerebral hemodynamics and intracranial pressure, medical and surgical treatment for hydrocephalus, and the intensive care management of patients in the acute severe stage of the illness. Very little data are available to address these issues with good evidence and so institutional preferences are common; this is perhaps most notable for the management of hydrocephalus, and so in this the review highlights our personal practice. The brain needs protection while the source of the illness is addressed. Without attention to these aspects of management there will always be a limit to the effectiveness of antimicrobial therapy in TBM, so there is a strong imperative for the controversies to be resolved and the limitations of our current care to be addressed. Existing protocols should be rigorously examined and novel strategies to protect the brain should be explored. To this end, a prospective, multi-disciplinary and multi-centered approach may yield answers to the questions raised in this review.

Abstract
HIV-associated tuberculous meningitis (TBM) poses significant diagnostic and therapeutic challenges and carries a dismal prognosis. In this review, we present the clinical features and management of HIV-associated TBM, and compare this to disease in HIV-uninfected individuals. Although the clinical presentation, laboratory findings and radiological features of TBM are similar in HIV-infected and HIV-uninfected patients, some important differences exist. HIV-infected patients present more frequently with extra-meningeal tuberculosis and systemic features of HIV infection. In HIV-associated TBM, clinical course and outcome are influenced by profound immunosuppression at presentation, emphasising the need for earlier diagnosis of HIV infection and initiation of antiretroviral treatment.

Abstract
Tuberculous meningitis is the most dangerous form of tuberculosis, yet our understanding of disease pathogenesis is based upon studies performed in the 1920s, our diagnostic methods are dependent upon those developed in the 1880 s, and our treatment has advanced little since the introduction of isoniazid in the 1950s. The authors focus this review on three important questions. First, how does Mycobacterium tuberculosis reach the brain? Second, what is the best way of identifying patients who require early empiric antituberculosis therapy? Third, what is the best way of managing tuberculous hydrocephalus?

British Infection Society guidelines for the diagnosis and treatment of tuberculosis of the central nervous system in adults and children. J Infect 2009; 59:167-87. [PMID: 19643501 DOI: 10.1016/j.jinf.2009.06.011] [Citation(s) in RCA: 316] [Impact Index Per Article: 21.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2009] [Revised: 06/26/2009] [Accepted: 06/26/2009] [Indexed: 12/14/2022]
Abstract
SUMMARY AND KEY RECOMMENDATIONS: The aim of these guidelines is to describe a practical but evidence-based approach to the diagnosis and treatment of central nervous system tuberculosis in children and adults. We have presented guidance on tuberculous meningitis (TBM), intra-cerebral tuberculoma without meningitis, and tuberculosis affecting the spinal cord. Our key recommendations are as follows: 1. TBM is a medical emergency. Treatment delay is strongly associated with death and empirical anti-tuberculosis therapy should be started promptly in all patients in whom the diagnosis of TBM is suspected. Do not wait for microbiological or molecular diagnostic confirmation. 2. The diagnosis of TBM is best made with lumbar puncture and examination of the cerebrospinal fluid (CSF). Suspect TBM if there is a CSF leucocytosis (predominantly lymphocytes), the CSF protein is raised, and the CSF:plasma glucose is <50%. The diagnostic yield of CSF microscopy and culture for Mycobacterium tuberculosis increases with the volume of CSF submitted; repeat the lumbar puncture if the diagnosis remains uncertain. 3. Imaging is essential for the diagnosis of cerebral tuberculoma and tuberculosis involving the spinal cord, although the radiological appearances do not confirm the diagnosis. A tissue diagnosis (by histopathology and mycobacterial culture) should be attempted whenever possible, either by biopsy of the lesion itself, or through diagnostic sampling from extra-neural sites of disease e.g. lung, gastric fluid, lymph nodes, liver, bone marrow. 4. Treatment for all forms of CNS tuberculosis should consist of 4 drugs (isoniazid, rifampicin, pyrazinamide, ethambutol) for 2 months followed by 2 drugs (isoniazid, rifampicin) for at least 10 months. Adjunctive corticosteroids (either dexamethasone or prednisolone) should be given to all patients with TBM, regardless of disease severity. 5. Children with CNS tuberculosis should ideally be managed by a paediatrician with familiarity and expertise in paediatric tuberculosis or otherwise with input from a paediatric infectious diseases unit. The Children's HIV Association of UK and Ireland (CHIVA) provide further guidance on the management of HIV-infected children (www.chiva.org.uk). 6. All patients with suspected or proven tuberculosis should be offered testing for HIV infection. The principles of CNS tuberculosis diagnosis and treatment are the same for HIV infected and uninfected individuals, although HIV infection broadens the differential diagnosis and anti-retroviral treatment complicates management. Tuberculosis in HIV infected patients should be managed either within specialist units by physicians with expertise in both HIV and tuberculosis, or in a combined approach between HIV and tuberculosis experts. The co-administration of anti-retroviral and anti-tuberculosis drugs should follow guidance issued by the British HIV association (www.bhiva.org).

Abstract
OBJECTIVE Tuberculous meningitis (TBM) is a massive global problem. The mortality and morbidity associated with the severe form of the disease are exceptionally high. Even when increased intracranial pressure is treated and full conventional therapy is commenced, cerebral ischemia can develop and is associated with a particularly poor prognosis. We sought to evaluate our experience with two patients with severe TBM and cerebral oxygenation monitoring. DESIGN Case report. SETTING Red Cross Children's Hospital, Cape Town. PATIENTS Two comatose patients with TBM. INTERVENTIONS Targeted interventions against low cerebral oxygenation in one patient. MEASUREMENTS AND MAIN RESULTS Cerebral tissue oxygenation (Ptio2) was measured. In both patients, Ptio2 monitoring demonstrated delayed cerebral ischemia despite the institution of full conventional therapy and the control of intracranial pressure. These data confirm that the vascular involvement in TBM is potentially progressive and that failure to diagnose infarction initially is not merely due to a delay in the radiologic appearance. The first patient developed extensive infarction, consistent with Ptio2 readings, and subsequently died after treatment withdrawal. Intervention in the second patient successfully reversed a precipitous decline of the Ptio2 readings and may have prevented infarction in this patient. CONCLUSIONS The development of delayed cerebral ischemia in TBM despite treatment is confirmed in these two patients. The reversal of a decline in Ptio2 readings suggests a possible benefit for cerebral oxygenation monitoring in selected patients with severe TBM.
