Abstract
BACKGROUND High intracranial pressure (ICP) is the most frequent cause of death and disability after severe traumatic brain injury (TBI). It is usually treated with general maneuvers (normothermia, sedation, etc.) and a set of first-line therapeutic measures (moderate hypocapnia, mannitol, etc.). When these measures fail, second-line therapies are initiated, which include: barbiturates, hyperventilation, moderate hypothermia, or removal of a variable amount of skull bone (secondary decompressive craniectomy). OBJECTIVES To assess the effects of secondary decompressive craniectomy (DC) on outcomes of patients with severe TBI in whom conventional medical therapeutic measures have failed to control raised ICP. SEARCH METHODS The most recent search was run on 8 December 2019. We searched the Cochrane Injuries Group's Specialised Register, CENTRAL (Cochrane Library), Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), Embase Classic + Embase (OvidSP) and ISI Web of Science (SCI-EXPANDED & CPCI-S). We also searched trials registries and contacted experts. SELECTION CRITERIA We included randomized studies assessing patients over the age of 12 months with severe TBI who either underwent DC to control ICP refractory to conventional medical treatments or received standard care. DATA COLLECTION AND ANALYSIS We selected potentially relevant studies from the search results, and obtained study reports. Two review authors independently extracted data from included studies and assessed risk of bias. We used a random-effects model for meta-analysis. We rated the quality of the evidence according to the GRADE approach. MAIN RESULTS We included three trials (590 participants). One single-site trial included 27 children; another multicenter trial (three countries) recruited 155 adults, the third trial was conducted in 24 countries, and recruited 408 adolescents and adults. Each study compared DC combined with standard care (this could include induced barbiturate coma or cooling of the brain, or both). All trials measured outcomes up to six months after injury; one also measured outcomes at 12 and 24 months (the latter data remain unpublished). All trials were at a high risk of bias for the criterion of performance bias, as neither participants nor personnel could be blinded to these interventions. The pediatric trial was at a high risk of selection bias and stopped early; another trial was at risk of bias because of atypical inclusion criteria and a change to the primary outcome after it had started. Mortality: pooled results for three studies provided moderate quality evidence that risk of death at six months was slightly reduced with DC (RR 0.66, 95% CI 0.43 to 1.01; 3 studies, 571 participants; I2 = 38%; moderate-quality evidence), and one study also showed a clear reduction in risk of death at 12 months (RR 0.59, 95% CI 0.45 to 0.76; 1 study, 373 participants; high-quality evidence). Neurological outcome: conscious of controversy around the traditional dichotomization of the Glasgow Outcome Scale (GOS) scale, we chose to present results in three ways, in order to contextualize factors relevant to clinical/patient decision-making. First, we present results of death in combination with vegetative status, versus other outcomes. Two studies reported results at six months for 544 participants. One employed a lower ICP threshold than the other studies, and showed an increase in the risk of death/vegetative state for the DC group. The other study used a more conventional ICP threshold, and results favoured the DC group (15.7% absolute risk reduction (ARR) (95% CI 6% to 25%). The number needed to treat for one beneficial outcome (NNTB) (i.e. to avoid death or vegetative status) was seven. The pooled result for DC compared with standard care showed no clear benefit for either group (RR 0.99, 95% CI 0.46 to 2.13; 2 studies, 544 participants; I2 = 86%; low-quality evidence). One study reported data for this outcome at 12 months, when the risk for death or vegetative state was clearly reduced by DC compared with medical treatment (RR 0.68, 95% CI 0.54 to 0.86; 1 study, 373 participants; high-quality evidence). Second, we assessed the risk of an 'unfavorable outcome' evaluated on a non-traditional dichotomized GOS-Extended scale (GOS-E), that is, grouping the category 'upper severe disability' into the 'good outcome' grouping. Data were available for two studies (n = 571). Pooling indicated little difference between DC and standard care regarding the risk of an unfavorable outcome at six months following injury (RR 1.06, 95% CI 0.69 to 1.63; 544 participants); heterogeneity was high, with an I2 value of 82%. One trial reported data at 12 months and indicated a clear benefit of DC (RR 0.81, 95% CI 0.69 to 0.95; 373 participants). Third, we assessed the risk of an 'unfavorable outcome' using the (traditional) dichotomized GOS/GOS-E cutoff into 'favorable' versus 'unfavorable' results. There was little difference between DC and standard care at six months (RR 1.00, 95% CI 0.71 to 1.40; 3 studies, 571 participants; low-quality evidence), and heterogeneity was high (I2 = 78%). At 12 months one trial suggested a similar finding (RR 0.95, 95% CI 0.83 to 1.09; 1 study, 373 participants; high-quality evidence). With regard to ICP reduction, pooled results for two studies provided moderate quality evidence that DC was superior to standard care for reducing ICP within 48 hours (MD -4.66 mmHg, 95% CI -6.86 to -2.45; 2 studies, 182 participants; I2 = 0%). Data from the third study were consistent with these, but could not be pooled. Data on adverse events are difficult to interpret, as mortality and complications are high, and it can be difficult to distinguish between treatment-related adverse events and the natural evolution of the condition. In general, there was low-quality evidence that surgical patients experienced a higher risk of adverse events. AUTHORS' CONCLUSIONS Decompressive craniectomy holds promise of reduced mortality, but the effects of long-term neurological outcome remain controversial, and involve an examination of the priorities of participants and their families. Future research should focus on identifying clinical and neuroimaging characteristics to identify those patients who would survive with an acceptable quality of life; the best timing for DC; the most appropriate surgical techniques; and whether some synergistic treatments used with DC might improve patient outcomes.

Abstract
Chronic subdural hematoma is a frequent type of hemorrhage, which terminates with mortality if not diagnosed and treated early. The aim of this clinical study is to evaluate the patients with unilateral and bilateral recurrent chronic subdural hematoma. The study group consisted of 13 cases with unilateral and bilateral recurrent chronic subdural hematomas who underwent aggressive wide craniotomy, duraectomy, inner and outer membranectomy, dural border coagulation, incision through cortical vein trace and hang up of dural edge, between 2009 - 2016. All of our patients were diagnosed by preoperative Magnetic Resonance Imaging. We evaluated the age, gender, complaints and neurologic signs, localization and thickness of the hematoma. We can estimate that wide craniotomy, duraectomy and membranectomy is a good option in preventing recurrent chronic subdural hematoma and complications.

Abstract
OBJECTIVEDecompressive craniectomy (DC) is an established part of treatment in patients suffering from malignant infarction of the middle cerebral artery (MCA) or traumatic brain injury (TBI). However, no clear evidence for intracranial pressure (ICP)-guided therapy after DC exists. The lack of this evidence might be due to the frequently used, but simplified threshold for ICP of 20 mm Hg, which determines further therapy. Therefore, the objective of this study was to evaluate this threshold's accuracy and to investigate the course of ICP values with respect to neurological outcome.METHODSData on clinical characteristics and parameters of the ICP course on the intensive care unit were collected retrospectively in 102 patients who underwent DC between December 2007 and April 2014 at the authors' institution. The postoperative ICP course in the first 168 hours was recorded and analyzed. From these findings, ICP thresholds discriminating favorable from unfavorable outcome were calculated using conditional inference tree analysis. Additionally, survival analysis was performed using the Kaplan-Meier method. Prognostic factors were assessed via univariate analysis and multivariate logistic regression. Favorable outcome was defined as a score of 0–4 on the modified Rankin Scale.RESULTSMultivariate logistic regression revealed that anisocoria, diagnosis, and ICP values differed significantly between the outcome groups. ICP values in the favorable and unfavorable outcome groups differed significantly (p < 0.001), while the mean ICP of both groups lay below the limit of 20 mm Hg (17.5 and 11.5 mm Hg, respectively). These findings were reproduced when analyzing the underlying pathologies of TBI and MCA infarction separately. Based on these findings, optimized time-dependent threshold values were calculated and found to be between 10 and 17 mm Hg. These values significantly distinguished favorable from unfavorable outcome and predicted 30-day mortality (p < 0.001).CONCLUSIONSThis study systematically evaluated ICP levels in a long-term analysis after DC and provides new, surprisingly low, time-dependent ICP thresholds for these patients. Future trials investigating the benefit of ICP-guided therapy should take these thresholds into consideration and validate them in further patient cohorts.

Abstract
Hypertensive intracerebral hemorrhage (ICH) has high morbidity and mortality rates. Decompressive craniectomy (DC) is generally used for the treatment of cases associated with refractory increased intracranial pressure (ICP). In this study, we investigated the beneficial effects of adding DC and expansive duraplasty (ED) to hematoma evacuation in patients who underwent surgery for large hypertensive ICH. A prospective randomized controlled clinical trial where 40 patients diagnosed having large hypertensive ICH was randomly allocated to either group A or B, each comprised 20 patients. Group A patients, the treatment group, were submitted to hematoma evacuation together with DC and ED, whereas group B patients, the control group, were submitted only to hematoma evacuation. Twenty-three (57.5 %) of the patients were males, with an overall age range of 34-79 years (mean 59.3 years). Preoperative Glasgow Coma Scale (GCS) scores in group A ranged from 4 to 13 (mean 7.1), while in group B it ranged from 4 to 12 (mean 6.8). Postoperative hydrocephalus occurred in 3 (15 %) patients in group A and in 4 (20 %) patients in group B, whereas meningitis occurred in one patient (5 %) in group A. The mortality rate was 2 (10 %) patients in group A as compared to 5 (25 %) patients in group B (p = 0.407). High admission GCS (p = 0.0032), younger age (p = 0.0023), smaller hematoma volume (p = 0.044), subcortical hematoma location (p = 0.041), absent or minimal preoperative (p = 0.0068), and postoperative (p = 0.0031) midline shift as well as absent intraventricular extension of the hematoma (p = 0.036) contributed significantly to a better outcome. Selected patients' subgroups who benefited from adding DC and ED to ICH evacuation were age category of 30 to less than 50 (p = 0.0015) and from 50 to less than 70 (p = 0.00619) as well as immediate preoperative GCS from 6 to 8 (p = 0.000436) and from 9 to 12 (p = 0.00774). At 6 months' follow-up, 14 (70 %) patients of group A had favorable outcome as compared to 4 (20 %) patients of group B (p = 0.0015). Adding DC with ED to evacuation of a large hypertensive hemispheric ICH might improve the outcome in selected group of patients.

Abstract
Patients suffering from uncontrollable intracranial hypertension due to posttraumatic brain swelling (BS) generally either die or survive in an extremely disabled state. Decompressive craniectomy (DC) with dural augmentation may be the best method to assist these patients. However, the efficacy of DC on functional outcomes remains controversial. One of the factors contributing to poor outcomes could be intraoperative brain extrusion, which is an acute potential complication of DC. The authors have adopted a new surgical technique for traumatic BS that can prevent and control massive intraoperative BS (IOS). In the past 3 years, the authors have used a unique technique, called "gradual and controlled decompression", in the treatment of posttraumatic BS. This procedure consists of creating numerous small dural openings and removing clots; enlarging fenestration in the frontal and temporal basal regions to detect and treat brain contusion; making U-shaped, discontinuous, small dural incisions around the circumference of the craniotomy; and performing an augmentation duraplasty through the discontinuous small opening with dural prosthetic substances. This technique has been employed in 23 patients suffering from posttraumatic BS. In all cases, IOS was prevented and controlled through gradual stepwise decompression, and expanded duraplasty was performed successfully. This new surgical approach for posttraumatic BS can prevent severe extrusion of the brain through the craniotomy defect and allows the gradual and gentle release of the subdural space. Further clinical studies should be conducted to estimate the impact of this new technique on morbidity and mortality rates.

Abstract
Abstract:Background:Intracranial hypertension can cause secondary damage after a traumatic brain injury. Aggressive medical management might not be sufficient to alleviate the increasing intracranial pressure (ICP), and decompressive craniectomy (DC) can be considered. Decompressive craniectomy can be divided into categories, according to the timing and rationale for performing the procedure: primary (done at the time of mass lesion evacuation) and secondary craniectomy (done to treat refractory ICP). Most studies analyze primary and secondary DC together. Our hypothesis is that these two groups are distinct and the aim of this retrospective study is to evaluate the differences in order to better predict outcome after DC.Methods:Seventy patients had DC over a period of four years at our center. They were divided into two groups based on the timing of the DC. Primary DC (44 patients) was done within 24 hours of the injury for mass lesion evacuation. Secondary DC (26 patients) was done after 24 hours and purely for the treatment of refractory ICP. Pre-op characteristics and post-op outcomes were compared between the two groups.Results:There was a significant difference in the mechanism of injury, the pupil abnormalities and Marshall grade between primary and secondary DC. There was also a significant difference in outcome with primary DC showing 45.5% good outcome and 40.9% mortality and secondary DC showing 73.1% good outcome and 15.4% mortality.Conclusions:Primary and secondary DC have different indications and patients characteristics. Outcome prediction following DC should be adjusted according to the surgical indication.

Abstract
Contralateral acute subdural hematoma (ASDH) occurring after removal of traumatic ASDH is a rare, but nearly devastating postoperative complication. We treated a 26-year-old male who developed a contralateral ASDH shortly after craniectomy for evacuation of a traumatic ASDH. Burr-hole craniotomy was performed before decompressive craniectomy, and the bleeding source was a cortex artery within the frontal lobe contusion. Despite supportive therapy with barbiturate and mild hypothermia he expired 3 days later of brain death. Literature review suggests that the old are more susceptible to contralateral ASDH following evacuation of traumatic ASDH. Contralateral ASDH following evacuation of traumatic ASDH is a rare but potentially lethal complication, so neurosurgeons should try to detect such contralateral hematoma formation and prevent clinical deterioration.

Abstract
Intracerebral hemorrhage (ICH) is devastating, with high mortality rates, but its optimum management has not been fully established. Decompressive hemicraniectomy is a surgical procedure used to relieve the malignant elevation of intracranial pressure. The application of decompressive hemicraniectomy in patients with hemispheric ICH has been much less common, although several studies have shown the usefulness of this procedure for large hemispheric ICH. In this review, the present knowledge of the safety and efficacy of this procedure are evaluated. The authors conclude that decompressive hemicraniectomy with hematoma evacuation for large ICH might be a safe and effective procedure in patients with severely disturbed consciousness and large hematoma volume.

Abstract
Hemispheric hypertensive intracerebral hemorrhage (ICH) has a high mortality rate. Decompressive craniectomy (DC) has generally been used for the treatment of severe traumatic brain injury, aneurysmal subarachnoid hemorrhage, and hemispheric cerebral infarction. However, the effect of DC on hemispheric hypertensive ICH is not well understood. To investigate the effects of DC for treating hemispheric hypertensive ICH, we retrospectively reviewed the clinical and radiological findings of 21 patients who underwent DC for hemispheric hypertensive ICH. Eleven of the patients were male and 10 were female, with an age range of 22-75 years (mean, 56.6 years). Their preoperative Glasgow Coma Scale scores ranged from 3 to 13 (mean, 6.9). The hematoma volumes ranged from 33.4 to 98.1 mL (mean, 74.2 mL), and the hematoma locations were the basal ganglia in 10 patients and the subcortex in 11 patients. Intraventricular extensions were observed in 11 patients. With regard to the complications after DC, postoperative hydrocephalus developed in ten patients, and meningitis was observed in three patients. Six patients had favorable outcomes and 15 had poor outcomes. The mortality rate was 10 %. A statistical analysis showed that the GCS score at admission was significantly higher in the favorable outcome group than that in the poor outcome group (P = 0.029). Our results suggest that DC with hematoma evacuation might be a useful surgical procedure for selected patients with large hemispheric hypertensive ICH.

Abstract
BACKGROUND The occurrence of a contralateral acute epidural hematoma (AEDH) following removal of an acute subdural hematoma (ASDH) is a rare but nearly devastating postoperative complication. Here, we describe a series of five patients with contralateral AEDH and provide a review of the literature to elucidate the characteristics and improve management of these patients. METHODS A total of 386 patients underwent ASDH evacuations in our hospital between August 2008 and July 2011. Five of these patients (1.3 %) developed AEDH that required surgery. Thirty-two additional patients were identified by a search of the PubMed database. Clinical features, surgical treatment, and outcomes (scored by Glasgow outcome scale, GOS) of the collective 37 AEDH cases were analyzed retrospectively. RESULTS Contralateral AEDH after ASDH evacuation occurred in 27 males (73 %) and 10 females (27 %) (mean age: 35.9 ± 14.2 years). Twenty-six patients (70 %) had unfavorable outcomes (GOS 1-3), and 11 patients (30 %) had favorable outcomes (GOS 4-5). Contralateral skull fractures and intraoperative acute brain swelling occurred in 30 (81 %) and 28 (76 %) patients, respectively. The preoperative Glasgow coma score (GCS) was significantly associated with outcome (p < 0.05). CONCLUSIONS Lower preoperative GCS score is an independent risk factor for prognosis of contralateral AEDH after ASDH. Postoperative management should include assessment of AEDH in patients treated for contralateral skull fractures and who experienced intraoperative acute brain swelling. We recommend early decompression with a burr-hole craniotomy, immediately followed by a decompressive craniectomy. This strategy provides gradual decompression, while advancing the initial surgical time and preventing the suddle decreased tamponade effect. As such, it may help decrease the risk of contralateral AEDH associated with decompression.

Abstract
OBJECTIVE AND BACKGROUND Linguistic function is one of vulnerable aspects of traumatic brain injury (TBI) which may have destructive effects on patients' communicative activities and daily life, years following trauma. This paper attempts to answer the controversy whether surgery affects increase and decrease of linguistic impairment or not. MATERIALS AND METHODS Two hundred forty-one TBI patients aged 18-65 with abnormal CT findings and at least 20 minute post-trauma amnesia (PTA), who were conscious at discharge, participated in this study. Based on operative intervention, the samples were divided into two groups: operative and nonoperative. Cognitive and aphasic deficits were inspected formally and pragmatic disorder was informally appraised at discharge. RESULTS The groups had no significant differences in aphasia incidence and language pragmatic impairment, though they were significantly distinctive in aphasia subcategories and cognitive deficit after trauma. Fluent aphasia was more common in both groups alike. In aphasia subcategories, however, transcortical sensory aphasia (TSA) in operative and anomia in nonoperative group were the most prevalent. Several variables appeared strikingly related to higher aphasia in operative groups as follows: moderate to severe injury, 18-35 and over 50 years of age, more than 1 week PTA, intracranial surgery of multiple lesions in left or bilateral hemisphere fronto-temporal cortex plus post-trauma cognitive and pragmatic impairments, and diffuse axonal injuries. DISCUSSION Almost certainly, meaningful drop of cognitive function post surgery roots back in significant loss of initial consciousness level. Related factors to postoperative aphasia suggest taking policies through surgery intervention. Discerning the indispensable contributions of neurosurgeons, neurolinguists, and neuroscientists, results inspire more clinical future studies.

Abstract
INTRODUCTION Diffuse brain edema has been described as a major cause of intracranial hypertension (IH) following traumatic brain injury (TBI), and several studies suggest that it may be more frequent in children than in adults. While most cases of IH following TBI are present from the beginning, several studies have described a subgroup of patients with delayed elevations in intracranial pressure (ICP). METHODS Retrospective review of severe pediatric TBI cases admitted to a single institution during a 6-year period. Patients were classified into three groups, based on the temporal evolution of ICP: patients who evolved without IH, patients who had IH at admission and patients with delayed IH. A risk factor analysis was performed to find differences between these groups. RESULTS 31 cases of severe pediatric TBI were analyzed. 13 patients were female and 18 male, with an average age of 8.9 years. 4 patients met the described criteria for delayed IH; the only significant risk factor was presence of edema at the initial brain CT (p = 0.008). 3 additional patients presented clinical deterioration after 48 h and signs of brain edema in the CT, after ICP monitoring had been discontinued. CONCLUSIONS Late-onset IH is a relatively common clinical condition in the pediatric population with severe TBI (present in 13% of the cases in our series), and the presence of a Marshall III CT scan at admission is a significant risk factor for this condition. Pediatric patients may benefit from a more prolonged period of ICP monitoring than adults, and the lack of amelioration of brain edema at follow-up brain CT (even with normal ICP values) may be an indication that more prolonged monitoring is needed.

Abstract
Decompressive craniectomy is one therapeutic option for severe traumatic brain injury (TBI), and it has long been used for the treatment of patients with malignant post-traumatic brain edema. A lack of definitive evidence, however, prevents physicians from drawing any conclusions about the effects of decompressive craniectomy for the treatment of TBI. Therefore, the aim of the present study was to investigate the influence of decompressive craniectomy on post-traumatic brain edema formation. The aquaporin-4 (AQP4) water channel is predominantly expressed in astrocytes, and it plays an important role in the regulation of brain water homeostasis. In the present study, we investigated the time course of AQP4 expression and the water content of traumatized cortex following decompressive craniectomy after TBI. Adult male Sprague-Dawley rats (300-400 g) were subjected to lateral fluid percussion injury using the Dragonfly device. The effect of decompressive craniectomy was studied in traumatized rats without craniectomy (closed skull, DC-), and in rats craniectomized immediately after trauma (DC+). AQP4 expression was investigated with a Western blot analysis and immunohistochemistry. Brain edema was measured using the wet weight/dry weight method. At 48 h after TBI, AQP4 expression of the DC- group was significantly increased compared with the DC+ group (p < 0.01). In addition, the cortical water content of the DC- group was significantly increased compared to the DC+ group at the same time point (p < 0.05). The present results suggest that decompressive craniectomy may affect AQP4 expression and reduce brain edema formation after TBI.

Abstract
Decompressive craniectomy (DC) is the surgical management removing part of the skull vault over a swollen brain used to treat elevated intracranial pressure that is unresponsive to maximal medical therapy. The commonest indication for DC is traumatic brain injury (TBI) or middle cerebral artery (MCA) infarction, though DC has been reported to have been used for treatment of aneurysmal subarachnoid haemorrhage and venous infarction. Despite an increasing number of reports supportive of DC, the controversy over the suitability of the procedure and criteria for patient selection remains unresolved. Although the majority of published studies are retrospective, the recent publication of several randomised prospective studies prompts a re-evaluation of the use of DC. We review the literature concerning the pathophysiology, indication, surgical techniques and timing, complications and long-term effects of DC (including reversal with cranioplasty), in order to rationalise its use. We conclude that at the time of this review, though we cannot support the routine use of DC in TBI or MCA stroke, there is evidence that early and aggressive use of DC in TBI patients with intracranial haematomas or younger malignant MCA stroke patients may improve outcome. Though the results of the DECRA trial suggest that primary DC may worsen outcome, the decision to perform DC after diffuse TBI is still individualised. We await the results of the RESCUEicp trial to ascertain whether an evidence-based protocol for its use can be agreed in the future.

Abstract
BACKGROUND The aim of this study was to compare the predicted outcome with observed outcome in those patients who have had a unilateral decompressive craniectomy following evacuation of an intracranial mass lesion and to consider some of the ethical issues that need to be addressed when performing life-saving but non-restorative surgery. METHODS By using the web-based outcome prediction model developed by the CRASH trial collaborators predicted and observed outcomes were compared for those patients who had had a unilateral decompression after evacuation of a mass lesion in the two major neurotrauma hospitals in Western Australia between 2004 and 2008. Three cases were selected with differing outcome predictions. RESULTS For the three selected cases the predicted risk of an unfavourable outcome at 6 months was 65.8%, 78.9% and 91.3%, respectively. For the 11 patients in this cohort with an outcome prediction between 61% and 70%, the observed outcome at 18 months (GOS) was: 5 had a good outcome, 4 were moderately disabled, and 3 were severely disabled. For the ten patients with an outcome prediction between 90-100%, observed outcome confirmed: one patient was moderately disabled, four patients were severely disabled, one patient was in a permanent vegetative state, and four patients had died. CONCLUSION As the index of injury severity (as adjudged by the CRASH outcome prediction model) increases, clinical decision making and discussion with surrogates must reflect the evidence provided by observed outcome, prior to life-saving but potentially non-restorative decompressive surgery.

Abstract
Decompressive craniectomy is a neurosurgical technique in which a portion of the skull is removed to reduce intracranial pressure. The rationale for this procedure is based on the Monro-Kellie Doctrine; expanding the physical space confining edematous brain tissue after traumatic brain injury will reduce intracranial pressure. There is significant debate over the efficacy of decompressive craniectomy despite its sound rationale and historical significance. Considerable variation in the employment of decompressive craniectomy, particularly for secondary brain injury, explains the inconsistent results and mixed opinions of this potentially valuable technique. One way to address these concerns is to establish a consistent methodology for performing decompressive craniectomies. The purpose of this paper is to begin accomplishing this goal and to emphasize the critical points of the hemicraniectomy and bicoronal (Kjellberg type) craniectomy.

Abstract
PURPOSE Diabetic ketoacidosis (DKA), a well-known complication of diabetes mellitus, is associated with severe diffuse cerebral edema leading to brain herniation and death. Survival from an episode of symptomatic cerebral edema has been associated with debilitating neurological sequelae, including motor deficits, visual impairment, memory loss, seizures, and persistent vegetative states. A review of the literature reveals scant information regarding the potential surgical options for these cases. The authors present their case in which they used a craniectomy to treat this life-threatening condition. METHODS After reportedly suffering nausea and vomiting, a 12-year-old male presented to the emergency room with lethargy and was diagnosed with acute DKA. After appropriate treatment, the patient became comatose. A CT scan revealed diffuse cerebral edema. To decrease intracranial pressure and prevent further progression of brain herniation, a bifrontal decompressive craniectomy with duraplasty was performed. RESULTS The patient's neurological function gradually improved, and he returned to school and his regular activities with only minimal cognitive deficits. CONCLUSION Given the high mortality and morbidity associated with DKA-related edema, we believe decompressive craniectomy should be considered for malignant cerebral edema and herniation syndrome.

Abstract
Refractory intracranial hypertension is a leading cause of poor neurological outcomes in patients with severe traumatic brain injury. Decompressive craniectomy has been used in the management of refractory intracranial hypertension for about a century, and is presently one of the most important methods for its control. However, there is still a lack of conclusive evidence for its efficacy in terms of patient outcome. In this article, we focus on the technical aspects of decompressive craniectomy and review different methods for this procedure. Moreover, we review technical improvements in large decompressive craniectomy, which is currently recommended by most authors and is aimed at increasing the decompressive effect, avoiding surgical complications, and facilitating subsequent management. At present, in the absence of prospective randomized controlled trials to prove the role of decompressive craniectomy in the treatment of traumatic brain injury, these technical improvements are valuable.

Abstract
OBJECTIVE Adequate management of increased intracranial pressure (ICP) is critical in patients with traumatic brain injury (TBI), and decompressive craniectomy is widely used to treat refractory increased ICP. The authors reviewed and analyzed complications following decompressive craniectomy for the management of TBI. METHODS A total of 89 consecutive patients who underwent decompressive craniectomy for TBI between February 2004 and February 2009 were reviewed retrospectively. Incidence rates of complications secondary to decompressive craniectomy were determined, and analyses were performed to identify clinical factors associated with the development of complications and the poor outcome. RESULTS Complications secondary to decompressive craniectomy occurred in 48 of the 89 (53.9%) patients. Furthermore, these complications occurred in a sequential fashion at specific times after surgical intervention; cerebral contusion expansion (2.2 ± 1.2 days), newly appearing subdural or epidural hematoma contralateral to the craniectomy defect (1.5 ± 0.9 days), epilepsy (2.7 ± 1.5 days), cerebrospinal fluid leakage through the scalp incision (7.0 ± 4.2 days), and external cerebral herniation (5.5 ± 3.3 days). Subdural effusion (10.8 ± 5.2 days) and postoperative infection (9.8 ± 3.1 days) developed between one and four weeks postoperatively. Trephined and post-traumatic hydrocephalus syndromes developed after one month postoperatively (at 79.5 ± 23.6 and 49.2 ± 14.1 days, respectively). CONCLUSION A poor GCS score (≤ 8) and an age of ≥ 65 were found to be related to the occurrence of one of the above-mentioned complications. These results should help neurosurgeons anticipate these complications, to adopt management strategies that reduce the risks of complications, and to improve clinical outcomes.

Abstract
INTRODUCTION The purpose of this study was to assess the role of decompressive craniectomy (DC) inpatients with post-traumatic intractable intracranial hypertension (ICH) in the absence of an evacuable intracerebral haemorrhage. METHODS Retrospective study at LAC+USC Medical Centre including patients who underwent DC for post-traumatic malignant brain swelling or ICH without space occupying haemorrhage, during the period 01/2004 to 12/2008. The analysis included the effect of DC on intracranial pressure (ICP) and timing of DC on functional outcomes and survival. RESULTS Of 106 patients who underwent DC, 43 patients met inclusion criteria. Of those, 34 were operated within the first 24 h from admission. DC decreased the ICP significantly from 37.8 ± 12.1 mmHg to 12.7 ± 8.2 mmHg in survivors and from 52.8 ± 13.0 to 32.0 ± 17.3 mmHg in non-survivors. Overall 25.6%died (11 of 43), and 32.5% (14 of 43) remained in vegetative state or were severely disabled. Favourable outcome (Glasgow Outcome Scale 4 and 5) was observed in 41.9% (18 of 43). No tendency towards either increased or decreased incidence in favourable outcome was found relative to the time from admission to DC.Six of the 18 patients (33.3%) with favourable outcome were operated on within the first 6 h. CONCLUSIONS DC lowers ICP and raises CPP to high normal levels in survivors compared to non-survivors.The timing of DC showed no clear trend, for either good neurological outcome or death. Overall, the survival rate of 74.4% is promising and 41.9% had favourable neurological outcome.

Abstract
BACKGROUND There is currently much interest in the use of decompressive craniectomy for patients with severe head injury. A number of studies have demonstrated that not only can the technique lower intracranial pressure but can also improve outcome. Whilst many patients who would otherwise have died or had a poor outcome now go on to make a good recovery, there is little doubt that complications can have a very significant impact on long term outcome. METHODS By using the corticosteroid randomisation after significant head injury (CRASH) collaborators outcome prediction model, three patients were selected who had a similar outcome prediction. All three patients developed intracranial hypertension following trauma and had a decompressive craniectomy. RESULTS Despite having a similar outcome prediction only one patient made an uneventful recovery. The remaining two patients suffered significant complications. CONCLUSIONS This report illustrates the potential clinical applications and limitations of an outcome prediction model and demonstrates the impact that complications can have on eventual outcome.

Abstract
OBJECTIVE To assess the intracranial hemodynamic modifications induced by a decompressive craniectomy (DC) after severe traumatic brain injury (TBI), using transcranial Doppler (TCD) ultrasonography and intracranial pressure (ICP) sensor. Mortality rate and neurological outcomes were also evaluated after this procedure. DESIGN A prospective study was carried out on 26 TBI patients, measuring transcranial Doppler and ICP before, immediately after, and 48 hours after the DC, allowing for statistical analysis of hemodynamic changes. The mortality rate and the neurological outcomes were assessed. MEASUREMENTS AND RESULTS After DC, ICP decreased from 37+/-17 to 20+/-13 mm Hg (P=0.0003). The global cerebral blood flow was modified with diastolic velocities rising from 23+/-15 to 31+/-13 cm/s (P=0.0038) and a pulsatility index decreasing from 1.70+/-0.66 to 1.18+/-0.37 (P=0.0012). This normalization of the global cerebral hemodynamics after the DC was immediate, symmetric, and constant during the first 48 hours. Outcome was evaluated at 6 months: good recovery or moderate disability was observed in 11 patients (42%), persistent vegetative state in 7 patients (27%), and 8 patients died (31%). CONCLUSIONS The DC results in a significant, immediate, and durable improvement of ICP associated with a normalization of cerebral blood flow velocities in most TBI patients with refractory intracranial hypertension.

We included in this retrospective study 7 patients who underwent in situ floating resin cranioplasty for cerebral decompression between December 2006 and March 2008. Of these patients, 3 patients had traumatic brain injury, 3 cerebral infarction, and one subarachnoid hemorrhage due to aneurysmal rupture. In situ floating resin cranioplasty for cerebral decompression can reduce complications related to the absence of a bone flap and allow reconstruction by secondary cranioplasty without difficulty. Furthermore, it provides cerebral protection and selectively eliminates the need for secondary cranioplasty in elderly patients or patients who have experienced unfavorable outcome.

Abstract
Analysis of slow waves in arterial blood pressure (ABP) and intracranial pressure (ICP) has been used as an index to describe cerebrovascular pressure-reactivity. It has been previously demonstrated that the pressure-reactivity index (PRx) can be used to reflect global cerebrovascular reactivity with changes in ABP. A positive PRx signifies a positive association between ABP and ICP, indicating a non-reactive vascular bed, while a negative PRx is reflective of intact cerebral autoregulation, where ABP waves provoke inversely correlated waves in ICP. To date, there has been no characterization of pressure-reactivity following decompressive craniectomy. In this prospective observational study, 33 patients who underwent surgery for acute brain injury with mass lesions for which the bone flap was left out were studied. The PRx was calculated as a moving correlation coefficient between 30 consecutive samples of values of ICP and ABP averaged for a period of 10 s. The time profiles of mean PRx values at 6-hourly intervals were analysed and compared with that in seven patients treated by medical therapy alone. The initial mean PRx 6 h after surgery was positive, indicative of disturbed pressure-reactivity. With time, PRx trended towards a more negative value, suggestive of an improving cerebrovascular autoregulatory reserve. The mean PRx 24 h after surgery was 0.28 (+/-0.26), while the mean PRx 72 h after surgery was 0.15 (+/-0.25) (p = 0.012). In contrast, the mean PRx in patients that were not decompressed did not change significantly with time (p = 0.357). Surgery in acute brain injury for which the bone flap is left out in anticipation of raised intracranial pressure in the postoperative period leads to an improved PRx as compared with controls. Craniectomy in this situation may have a contribution to the restoration of disturbed cerebrovascular pressure-reactivity.

Abstract
Decompressive hemicraniectomy is well accepted for the surgical treatment of intractable intracranial hypertension in cases in which medical management fails. Although it is performed as a life-saving procedure when death is imminent from intracranial hypertension, little is known about the functional outcomes for these patients on long-term follow-up. In this study, the authors performed a systematic review of the literature to examine neurological outcome after hemicraniectomy. A literature search revealed 29 studies that reported outcomes using GOS scores. The GOS scores were transformed to utility values for quality of life using a conversion method based on decision analysis modeling. Based on the literature, 1422 cases were analyzed. The average 6-month-postoperative mortality rate was 28.2%. The mean QOL value among survivors was 0.592, which corresponds roughly to a GOS score of 4. Although more studies are needed for validation of long-term neurological outcome after hemicraniectomy, the assumption that most patients remain in a vegetative state after this intervention is clearly incorrect.

Abstract
Decompressive surgery has since long been a promising therapeutic approach for patients with acute severe brain injury at risk to develop severe brain edema. The underlying rationale of removing part of the cranium is to create space for the expanding brain to prevent secondary damage to vital brain tissue. However, until recently, randomized controlled trials that demonstrate the efficacy of decompressive surgery or benefit for outcome were missing. This has changed since the results of 3 randomized trials on hemicraniectomy in malignant infarction of the middle cerebral artery have been published in 2007. In this article, the current evidence for decompressive surgery in the treatment of cerebral ischemia, intracranial hemorrhage, traumatic brain injury, inflammatory diseases, or severe metabolic derangements is reviewed. Although there is increasing evidence for the efficacy of decompressive surgery in reducing intracranial pressure and even mortality, a critical point remains the definition of good or acceptable outcome.

Abstract
BACKGROUND Many previous studies have reported that decompressive craniectomy has improved clinical outcomes in patients with intractable increased intracranial pressure (ICP) caused by various neurosurgical diseases. However there is no report that compares the effectiveness of the procedure in the different conditions. The authors performed decompressive craniectomy following a constant surgical indication and compared the clinical outcomes in different neurosurgical diseases. MATERIALS AND METHODS Seventy five patients who underwent decompressive craniectomy were analysed retrospectively. There were 28 with severe traumatic brain injury (TBI), 24 cases with massive intracerebral haemorrhage (ICH), and 23 cases with major infarction (MI). The surgical indications were GCS score less than 8 and/or a midline shift more than 6 mm on CT. The clinical outcomes were assessed on the basis of mortality and Glasgow Outcome Scale (GOS) scores. The changes of ventricular pressure related to the surgical intervention were also compared between the different disease groups. FINDINGS Clinical outcomes were evaluated 6 months after decompressive craniectomy. The mortality was 21.4% in patients with TBI, 25% in those with ICH and 60.9% in MI. A favourable outcome, i.e. GOS 4-5 (moderate disability or better) was observed in 16 (57.1%) patients with TBI, 12 (50%) with ICH and 7 (30.4%) with MI. The change of ventricular pressure after craniectomy and was 53.2 (reductions of 17.4%) and further reduced by 14.9% (with dural opening) and (24.8%) after returning to its recovery room, regardless of the diseases group. CONCLUSIONS According to the mortality and GOS scores, decompressive craniectomy with dural expansion was found to be more effective in patients with ICH or TBI than in the MI group. However, the ventricular pressure change during the decompressive craniectomy was similar in the different disease groups. The authors thought that decompressive craniectomy should be performed earlier for the major infarction patients.

Surgical complications secondary to decompressive craniectomy in patients with a head injury: a series of 108 consecutive cases. Acta Neurochir (Wien) 2008; 150:1241-7; discussion 1248.

Abstract
BACKGROUND Decompressive craniectomy is an important method for managing refractory intracranial hypertension in patients with head injury. We reviewed a large series of patients who underwent this surgical procedure to establish the incidence and type of postoperative complications. METHODS From 1998 to 2005, decompressive craniectomy was performed in 108 patients who suffered from a closed head injury. The incidence rates of complications secondary to decompressive craniectomy and risk factors for developing these complications were analysed. In addition, the relationship between outcome and clinical factors was analysed. FINDINGS Twenty-five of the 108 patients died within the first month after surgical decompression. A lower GCS at admission seemed to be associated with a poorer outcome. Complications related to surgical decompression occurred in 54 of the 108 (50%) patients; of these, 28 (25.9%) patients developed more than one type of complication. Herniation through the cranial defect was the most frequent complication within 1 week and 1 month, and subdural effusion was another frequent complication during this period. After 1 month, the "syndrome of the trephined" and hydrocephalus were the most frequent complications. Older patients and/or those with more severe head trauma had a higher occurrence rate of complications. CONCLUSIONS The potential benefits of decompressive craniectomy can be adversely affected by the occurrence of complications. Each complication secondary to surgical decompression had its own typical time window for occurrence. In addition, the severity of head injury was related to the development of a complication.

Abstract
Decompressive Craniectomy (DC) is used to treat elevated intracranial pressure that is unresponsive to conventional treatment modalities. The underlying cause of intracranial hypertension may vary and consequently there is a broad range of literature on the uses of this procedure. Traumatic brain injury (TBI), middle cerebral artery (MCA) infarction, and aneurysmal subarachnoid hemorrhage (SAH) are three conditions for which DC has been predominantly used in the past. Despite an increasing number of reports supportive of DC, the controversy over the suitability of the procedure and criteria for patient selection remains unresolved. Although the majority of published studies is retrospective, the recent publication of several randomized prospective studies prompts a reevaluation of the utility of DC. We review the literature concerning the use of DC in TBI, MCA infarction, and SAH and address the evidence regarding common questions pertaining to the timing of and laterality of the procedure. We conclude that at the time of this review, there still remains insufficient data to support the routine use of DC in TBI, stroke or SAH. There is evidence that early and aggressive use of DC in good-grade patients may improve outcome, but the notion that DC is indicated in these patients is contentious. At this point, the indication for DC should be individualized and its potential implications on long-term outcomes should be comprehensively discussed with the caregivers.

Abstract
BACKGROUND Usually, decompressive craniectomy (DC) in patients with increased intracranial pressure (ICP) is combined with resection of the dura and large-scale duroplasty. However, duroplasty is cumbersome, lengthens operation time and requires heterologous or autologous material. In addition, the swelling brain could herniate into the duroplasty with kinking of the superficial veins at the sharp cutting edges and subsequent ICP exacerbation. Several longitudinal durotomies avoid these limitations, but it remains a matter of discussion if durotomies reduce ICP sufficiently. METHODS DC was performed in ten patients (mean age 45 years) with increased ICP after head trauma or subarachnoid hemorrhage. After craniectomy, the dura was opened by three to four durotomies from midline to the temporal base. Duration of surgical procedure and ICP during each surgical step and postoperatively were recorded. FINDINGS Mean duration of surgery was 90 +/- 10 min. ICP prior to skin incision was 39 +/- 12 mmHg and dropped to 22 +/- 9 mmHg after craniectomy. During durotomy ICP decreased stepwise and reached stable values of 12 +/- 6 mmHg at the end of surgery. On days 1-10 after surgery, ICP values ranged between 12-17 mmHg. CONCLUSION This study showed that durotomy is a fast and easy, but likewise effective method to lower ICP further after craniectomy.

Abstract
The overall degree by which different patients may benefit from decompressive craniectomy (DC) remains controversial. In particular, the prognostic value of age has been investigated by very few studies. Many authors state there is no significant benefit in performing a DC in severe head injury after a certain age limit, with most placing the limit at 30-50 years of age. Between 1994 and 2004, 55 patients underwent DC at our institution. Advanced age did not constitute a contraindication to surgery for both ethical and cultural reasons. Thus, the data obtained were not biased by a selection of patients based on age. We analyzed potential predictors of outcome after DC, including sex, age, Glasgow Coma Scale (GCS), and presence of mass lesion. Chi-square test was used to compare categorical variables. The independent contribution of predictive factors to outcome was studied using logistic regression analysis. Initial GCS score was found to be an independent predictor of outcome (p = 0.001). No difference in the outcome was observed between patients with GCS 6-8 and GCS 9-15. These two groups have a better prognosis than patients with GCS 3-5. Logistic regression analysis showed age as an independent predictive factor to outcome (p = 0.005). A difference in outcome exists among patients over 65 and patients aged <or=65, while groups aged <40 and 40-65 showed no difference in outcome. Based on these findings, we believe that the age limit for performing DC should be revised.

Abstract
✓Decompressive craniectomy to relieve cerebral edema and intracranial hypertension due to traumatic brain injury is a generally accepted practice; however, the procedure remains controversial because of its uncertain effects on outcome, specific complications such as the syndrome of the sinking skin flap, and the need for subsequent cranioplasty. The authors developed a novel craniotomy technique using titanium bone plates in a hinged fashion, which maintains cerebral protection while reducing postoperative complications and eliminating subsequent cranioplasty procedures.
The authors conducted a retrospective review of data obtained in all consecutive patients who had undergone post-traumatic cerebral decompression craniotomy using the hinge technique at a Level I trauma facility between 1990 and 2004.
Twenty-five patients, most of whom were male (88%) and Caucasian (88%) with a mean age of 38.2 ± 16.1 years, underwent the hinge craniotomy. The in-hospital mortality rate was 48%, and good cerebral decompression was achieved. None of the patients required surgery for flap replacement. Long-term follow-up data showed that one patient required subsequent cranioplasty due to infection and one patient presented with cranial deformities. None of the patients presented with bone resorption or sinking flap syndrome.
The hinge technique effectively prevents procedure-related morbidity and the need for subsequent surgical bone replacement otherwise introduced by traditional decompressive craniectomy. A randomized controlled trial is required to substantiate these findings.

Abstract
Large cranial defects resulting from decompressive craniectomy performed for refractory intracranial hypertension after head trauma is one of the indications for cranioplasty, and this procedure is commonly performed 3 months after craniectomy. However, the large cranial defect would lead to the kinds of complications early during the phase of these patients' recovery, which would go against rehabilitation. This study retrospectively reviewed 23 patients undergoing early cranioplasty (5-8 weeks after craniectomy) in the last 4 years with a detailed choice of patients, outcome of complications after head trauma and large craniectomy, as well as assessment of prognosis. The early outcome (1 month later) revealed most of the patients who had conscious disturbance before the cranioplasty recovered their consciousness and presented an improved neurologic function. The long-dated prognosis (18 months later) revealed that 17 patients were good (independent patients) in this series (74%), whereas four patients survived with a severe disability (17%) and two remained in a vegetative state (9%). No dead patients or intracranial infection after the procedure were found in this study. Most patients' complications were relieved after the cranioplasty with improvements of symptoms or image of computed tomography scan. In conclusion, we consider that with the appropriate choice of patients and materials, early cranioplasty for large cranial defects after decompressive craniectomy would be safe and helpful for the improvement of patients' neurologic function and prognosis. To our knowledge, this series may be the first detailed report in English about early cranioplasty after decompressive craniectomy. We are going to perform prospective and retrospective contrastive studies to further confirm the effects of this procedure on the patients with large cranial defects after decompressive craniectomy.

Abstract
Intracerebral haemorrhage (ICH) accounts for 15 to 20% of strokes. The condition carries a higher morbidity and mortality than occlusive stroke. Despite considerable research effort, no therapeutic modality either medical or surgical has emerged with clear evidence of benefit other than in rare aneurysmal cases. Intracerebral haemorrhages can be divided into those that arise from pre-existing macroscopic vascular lesions - so called "ictohaemorrhagic lesions", and those that do not; the latter being the commoner. Most of the research that has been done on the benefits of surgery has been in this latter group. Trial data available to date precludes a major benefit from surgical evacuation in a large proportion of cases however there are hypotheses of benefit still under investigation, specifically superficial lobar ICH treated by open surgical evacuation, deeper ICH treated with minimally invasive surgical techniques, and decompressive craniectomy. When an ICH arises from an ictohaemorrhagic lesion, therapy has two goals: to treat the effects of the acute haemorrhage and to prevent a recurrence. Three modalities are available for treating lesions to prevent recurrence: stereotactic radiosurgery, endovascular embolisation, and open surgical resection. As with ICH without an underlying lesion there is no evidence to support surgical removal of the haemorrhage in most cases. An important exception is ICHs arising from intracranial aneurysms where there is good evidence to support evacuation of the haematoma as well as repair of the aneurysm.

Abstract
Severe traumatic brain injury (TBI) is one of the major causes of death in younger age groups. In Umeå, Sweden, an intracranial pressure (ICP) targeted therapy protocol, the Lund concept, has been used in treatment of severe TBI since 1994. Decompressive craniectomy is used as a protocol-guided treatment step. The primary aim of the investigation was to study the effect of craniectomy on ICP changes over time in patients with severe TBI treated by an ICP-targeted protocol. In this retrospective study, all patients treated for severe TBI during 1998-2001 who fulfilled the following inclusion criteria were studied: GCS <or= 8 at intubation and sedation, first recorded cerebral perfusion pressure (CPP) of >10 mm Hg, arrival within 24 h of trauma, and need of intensive care for >72 h. Craniectomy was performed when the ICP could not be controlled by evacuation of hematomas, sedation, ventriculostomy, or low-dose pentothal infusion. Ninety-three patients met the inclusion criteria. Mean age was 37.6 years. Twenty-one patients underwent craniectomy as a treatment step. We found a significant reduction of the ICP directly after craniectomy, from 36.4 mm Hg (range, 18-80 mm Hg) to 12.6 mm Hg (range, 2-51 mm Hg). During the following 72 h, we observed an increase in ICP during the first 8-12 h after craniectomy, reaching approximately 20 mm Hg, and later levelling out at approximately 25 mm Hg. The reduction of ICP was statistically significant during the 72 h. The outcome as measured by Glasgow Outcome Scale (GOS) did not significantly differ between the craniectomized group (DC) and the non-craniectomized group (NDC). The outcome was favorable (GOS 5-4) in 71% in the craniectomized group, and in 61% in the non-craniectomized group. Craniectomy is a useful tool in achieving a significant reduction of ICP overtime in TBI patients with progressive intracranial hypertension refractory to medical therapy. The procedure seems to have a satisfactory effect on the outcome, as demonstrated by a high rate of favorable outcome and low mortality in the craniectomized group, which did not significantly differ compared with the non-craniectomized group.

Abstract
Brain edema is a common pathophysiological process seen in many neurosurgical conditions. It can be localized in relation to focal lesions or generalized in diffuse types of brain injury. In addition to local adverse effects occurring at a cellular level, brain edema is associated with raised intracranial pressure (ICP), and both phenomena contribute to poor outcome in patients. One of the goals in treating patients with acute neurosurgical conditions in intensive care is to control brain edema and maintain ICP below target levels. The mainstay of treatment is medical therapy to reduce edema, but in certain patients--for example, those with diffuse severe traumatic brain injury (TBI) and malignant middle cerebral artery infarction--such treatment is not effective. In these patients, opening the skull (decompressive craniectomy) to reduce ICP is a potential option. In this review the authors discuss the role of decompressive craniectomy as a surgical option in patients with brain edema in the context of a variety of pathological entities. They also address the current evidence for the technique (predominantly observational series) and the ongoing randomized studies of decompressive craniectomy in TBI and ischemic stroke.
