Abstract
BACKGROUND AND OBJECTIVE At present, there is no consensus regarding the most optimal dural substitute to use for duroplasty in primary decompressive craniectomy (PDC) for traumatic brain injury (TBI). The author's objective was to conduct a retrospective analysis comparing 2 techniques of PDC: duroplasty using anterior-based vascularized galea pericranium (VP group) with synthetic dural substitute duroplasty (SR group). METHODS From April 2015 to February 2022, 379 craniotomies were done for TBI. The outcome of eligible 97 consecutive patients receiving PDC treatment were examined. Out of 97, 60 received vascularized galea pericranium and 37 received synthetic dural graft for dural augmentation. Propensity matching generated 28 pairs (56 patients) for analysis. The primary outcome was extended Glasgow Outcome Scale (GOS-E) measured at 6 months after injury. Secondary outcomes included were incidence of surgical complications (neurosurgical site infections, and hemorrhagic and hydrodynamic complications), surgical time, days in intensive care unit, hospital length of stay, hospital mortality, and GOS-E at 1 year after injury. RESULTS Patients in VP group, compared with those in SR group had better GOS-E score at 6 months (P = .011) and 1 year (P = .026). Hospital mortality (P = .342), days in intensive care unit (P = .574), hospital stay (P = .155), surgical time (P = .131), medical and surgical complications including neurosurgical infections, and hemorrhagic and hydrodynamic complications did not differ significantly in both groups. Complication of brain abscess was found exclusively in the SR group (P = .327). CONCLUSION In this retrospective study, adults who underwent PDC for TBI using anterior-based vascularized galea pericranial graft were associated with better clinical outcomes at 6 months and 1 year compared with standard repair group using synthetic dural substitute (G patch).

Abstract
Traumatic brain injury (TBI)-induced intracerebral hematoma is a major driver of secondary injury pathology such as neuroinflammation, cerebral edema, neurotoxicity, and blood-brain barrier dysfunction, which contribute to neuronal loss, motor deficits, and cognitive impairment. Cluster of differentiation 47 (CD47) is an antiphagocytic cell surface protein inhibiting hematoma clearance. This study was designed to evaluate the safety and efficacy of blockade of CD47 via intravenous (i.v.) administration of anti-CD47 antibodies following penetrating ballistic-like brain injury (PBBI) with significant traumatic intracerebral hemorrhage (tICH). The pharmacokinetic (PK) profile of the anti-CD47 antibody elicited that antibody concentration decayed over 7 days post-administration. Blood tests and necropsy analysis indicated no severe adverse events following treatment. Cerebral hemoglobin levels were significantly increased after injury, however, anti-CD47 antibody administration at 0.1 mg/kg resulted in a significant reduction in cerebral hemoglobin levels at 72 h post-administration, indicating augmentation of hematoma clearance. Immunohistochemistry assessment of glial fibrillary acidic protein (GFAP) and ionized calcium-binding adaptor molecule 1 (IBA1) demonstrated a significant reduction of GFAP levels in the lesion core and peri-lesional area. Based on these analyses, the optimal dose was identified as 0.1 mg/kg. Lesion volume showed a reduction following treatment. Rotarod testing revealed significant motor deficits in all injured groups but no significant therapeutic benefits. Spatial learning performance revealed significant deficits in all injured groups, which were significantly improved by the last testing day. Anti-CD47 antibody treated rats showed significantly improved attention deficits, but not retention scores. These results provide preliminary evidence that blockade of CD47 using i.v. administration of anti-CD47 antibodies may serve as a potential therapeutic for TBI with ICH.

Abstract
OBJECTIVE To date, there is no consensus on the surgery strategies of cranioplasty (CP) and ventriculoperitoneal shunt (VPS) placement. This meta-analysis aimed to investigate the safety of staged and simultaneous operation in patients with comorbid cranial defects with hydrocephalus to inform future surgery protocols. METHODS A meta-analysis of PubMed, Ovid, Web of Science, and Cochrane Library databases from the inception dates to February 8, 2023 adherent to PRISMA guidelines was conducted. The pooled analyses were conducted using RevMan 5.3 software. The outcomes included postoperative infection, reoperation, shunt obstruction, hematoma, and subdural effusion. RESULTS Of the 956 studies initially retrieved, 10 articles encompassing 515 patients were included. Among the total patients, 193 (37.48%) and 322 (62.52%), respectively, underwent simultaneous and staged surgeries. The finding of pooled analysis indicated that staged surgery was associated with lower rate of subdural effusion (14% in the simultaneous groups vs. 5.4% in the staged groups; OR = 2.39, 95% CI: 1.04-5.49, p = 0.04). However, there were no significant differences in overall infection (OR = 1.92, 95% CI: 0.74-4.97, p = 0.18), central nervous system infection (OR = 1.50, 95% CI: 0.68-3.31, p = 0.31), cranioplasty infection (OR = 1.58, 95% CI: 0.50-5.00, p = 0.44), shunt infection (OR = 1.30, 95% CI: 0.38-4.52, p = 0.67), reoperation (OR = 1.51, 95% CI: 0.38-6.00, p = 0.55), shunt obstruction (OR = 0.73, 95% CI: 0.25-2.16, p = 0.57), epidural hematoma (OR = 2.20, 95% CI: 0.62-7.86, p = 0.22), subdural hematoma (OR = 1.20, 95% CI: 0.10-14.19, p = 0.88), and intracranial hematoma (OR = 1.31, 95% CI: 0.42-4.07, p = 0.64). Moreover, subgroup analysis failed to yield new insights. CONCLUSIONS Staged surgery is associated with a lower rate of postoperative subdural effusion. However, from the evidence of sensitivity analysis, this result is not stable. Therefore, our conclusion should be viewed with caution, and neurosurgeons in practice should make individualized decisions based on each patient's condition and cerebrospinal fluid tap test.

Abstract
BACKGROUND As ground-level falls (GLFs) are a significant cause of mortality in elderly patients, field triage plays an essential role in patient outcomes. This research investigates how machine learning algorithms can supplement traditional t-tests to recognize statistically significant patterns in medical data and to aid clinical guidelines. METHODS This is a retrospective study using data from 715 GLF patients over 75 years old. We first calculated P-values for each recorded factor to determine the factor's significance in contributing to a need for surgery (P < .05 is significant). We then utilized the XGBoost machine learning method to rank contributing factors. We applied SHapley Additive exPlanations (SHAP) values to interpret the feature importance and provide clinical guidance via decision trees. RESULTS The three most significant P-values when comparing patients with and without surgery are as follows: Glasgow Coma Scale (GCS) (P < .001), no comorbidities (P < .001), and transfer-in (P = .019). The XGBoost algorithm determined that GCS and systolic blood pressure contribute most strongly. The prediction accuracy of these XGBoost results based on the test/train split was 90.3%. DISCUSSION When compared to P-values, XGBoost provides more robust, detailed results regarding the factors that suggest a need for surgery. This demonstrates the clinical applicability of machine learning algorithms. Paramedics can use resulting decision trees to inform medical decision-making in real time. XGBoost's generalizability power increases with more data and can be tuned to prospectively assist individual hospitals.

Abstract
Introduction Decompressive craniectomy (DC) can save brain tissue, but unfortunately it has many limitations and complications. Hinge craniotomy (HC), as less aggressive method seems to be adequate alternative not only to DC but also to conservative treatment. Research question Presentation of the results of modified surgical techniques of cranial decompression and comparing with more and less aggressive medical options. Material and methods A prospective clinical study was conducted during 86 months. Comatose patients who suffered refractory intracranial hypertension (RIH) were treated. Altogether, 137 patients have been evaluated. The final outcome of all patients in the study was evaluated after 6 months. Results Both surgical options resulted in adequate control of intracranial pressure (ICP). HC method was shown to have the lowest probability of worsening from a prior state of relative stability. Discussion and conclusion There was no statistically significant difference between methods to treatment of DC or HC, meaning the final outcome of patients treated in any manner. There was similar rate of early and late complications.

Abstract
OBJECTIVE Aesthetic complications following neurosurgical procedures impact patient quality of life and self-perception. Postoperative temporal hollowing is frequently seen after temporal craniotomy, resulting mainly from atrophy of the temporal muscle. Autologous fat grafting is a tailorable method to correct such approach-related sequelae. We herein present our clinical patient series and discuss pearls and pitfalls of this method. METHODS In this retrospective single-center study, correction of postoperative temporal hollowing using autologous fat grafting was performed in 16 patients. Temporal tissue thickness ratio was measured using magnetic resonance tomography images to visualize the graft. Patients, plastic surgeons and neurosurgeons evaluated the results independently using the herein presented scale. RESULTS The mean interval between the neurosurgical procedure and fat grafting was 62 months. A mean volume of 11.5 ml autologous fat was injected in an average of 2.5 sessions after initial rigotomy. Temporal tissue thickness was significantly augmented at a mean of 2.2 years after the operation (mean 0.71 ± 0.25, range 0.43-1.1; p=0.0214) as compared to the preoperative finding (mean 0.48 ± 0.1, range 0.32-0.6). Patients were more satisfied with the results than were surgeons, reflecting the significant impact of the deformity on patient self-esteem. CONCLUSIONS Autologous fat grafting is a valuable method for correcting postoperative temporal hollowing that provides stable results, high patient and surgeon satisfaction and can be tailored to the patient's individual needs. It should not be considered a merely aesthetic operation, but an important rehabilitation step towards restoring the patient's quality of life.

Abstract
BACKGROUND Cranioplasty is a critical intervention to restore the calvarium using autologous or alloplastic materials with single-stage composite scalp and calvarial reconstruction reserved for complex cases. This study aims to identify 30-day outcomes in scalp and calvarial reconstruction using the American College of Surgeons National Surgical Quality Improvement Program database. METHODS The authors conducted a retrospective analysis of the 2010 to 2018 American College of Surgeons National Surgical Quality Improvement Program database. Adult patients who underwent cranioplasty were identified using current procedural terminology coding and included by exposure type (autologous, alloplastic, composite, or other). Subjects with missing exposure or outcome data were excluded. Primary outcome was 30-day reoperation, whereas secondary outcomes were 30-day unplanned readmission and transfusion. Univariate analysis was completed to assess differences in demographics, comorbidities, and postoperative complications. Multivariable logistic regression was used to control for confounders. RESULTS In total, 1719 patients underwent cranioplasty (mean age 54.7 ± 15.3 years, 43.5% male), including 169(9.8%) autologous, 1303(75.8%) alloplastic, 32(1.9%) composite, and 215(12.5%) other procedures. Cranioplasty procedures were associated with 30-day complication and mortality rate of 16.5% and 2.4%, respectively. Composite cranioplasty was associated with decreased 30-day reoperation (adjusted odds ratios 0.11, 95% confidence interval 0.014-0.94, P = 0.044). There was no statistically significant difference in readmission between cranioplasty groups. Alloplastic cranioplasty was associated with decreased odds of postoperative transfusion (adjusted odds ratios 0.47, 95% confidence interval 0.27-0.84, P = 0.01). CONCLUSIONS Cranioplasty is an increasingly common procedure. Alloplastic cranioplasty is associated with decreased 30-day transfusion requirement, whereas single-stage composite reconstruction is a viable option and associated with decreased 30-day reoperation with no difference in readmission.

Abstract
Background Post-traumatic hydrocephalus (PTH) is a sequel of traumatic brain injury (TBI) that is seen more often in patients undergoing decompressive craniectomy (DC). It is associated with prolonged hospital stay and unfavorable outcomes. Objective To study the incidence and risk factors for development of PTH in patients undergoing DC in our institution and to review the literature on PTH with respect to incidence, risk factors, pathophysiology, and outcomes of management. Methods Data from 95 patients (among 220 patients who underwent DC for TBI and fulfilled the inclusion criteria) over a 5-year period at Christian Medical College, Vellore were collected and analyzed to study the incidence and possible risk factors for development of PTH. A review of the literature on PTH was performed by searching PUBMED resources. Results Thirty (31.6%) out of 95 patients developed post-traumatic ventriculomegaly, of whom seven (7.3%) developed symptomatic PTH, necessitating placement of ventriculoperitoneal shunt (VPS). No risk factor for development of PTH could be identified. The reported incidence of PTH in the literature is from 0.07% to 29%, with patients undergoing DC having a higher incidence. Younger age, subarachnoid hemorrhage, severity of TBI, presence of subdural hygroma, and delayed cranioplasty after DC are the main risk factors reported in the literature. Conclusions PTH occurs in a significant proportion of patients with TBI and can lead to unfavorable outcomes. PTH has to be distinguished from asymptomatic ventriculomegaly as early as possible so that a CSF diversion procedure can be planned early during development of PTH.

Abstract
BACKGROUND Archeological archives report cranioplasty as 1 of the oldest surgical procedures; however, it was not until the last century that true advances have been made. Alternative approaches are necessary to achieve optimal closure of the defect with fewer adverse effects. We aim to evaluate the use of human adipose-derived stem cells (hADSCs) alone or seeded in scaffolds as the main treatment for cranial bone defects and to assess human patient outcomes. METHODS A systematic review was performed by querying PubMed, Ovid MEDLINE, EMBASE, and Cumulative Index to Nursing and Allied Health Literature databases with the MeSH terms: "adipose-derived stem cells," "cranial bone defect," "stromal vascular factor," "fat grafting," as well as synonyms in combinations determined by our search strategy. We included human models that used hADSCs as primary therapy. We excluded studies in languages other than English. RESULTS One hundred ninety-four studies were identified after removal of duplicates. Four articles that used hADSCs as the main therapy to treat calvarial defects in humans were included. One article applied the cell therapy alone, and 3 used β-tricalcium phosphate granules as a scaffold to seed the hADSCs. CONCLUSIONS Bone regeneration was reached in a short and intermediate period using autologous hADSCs in humans with no major adverse effects in all 4 articles included. A long-term follow-up study (6 years) exhibited late infections and reabsorption of the β-tricalcium phosphate scaffold seeded with hADSCs.

Decompressive craniectomy (DC) is a life-saving procedure in severe traumatic brain injury, but is associated with higher rates of post-traumatic hydrocephalus (PTH). The relationship between the medial craniectomy margin's proximity to midline and frequency of developing PTH is controversial. The primary study objective was to determine whether average medial craniectomy margin distance from midline was closer to midline in patients who developed PTH after DC for severe TBI compared to patients that did not. The secondary objective was to determine if a threshold distance from midline could be identified, at which the risk of developing PTH increased if the DC was performed closer to midline than this threshold. A retrospective review was performed of 380 patients undergoing DC at a single institution between March 2004 and November 2014. Clinical, operative and demographic variables were collected, including age, sex, DC parameters and occurrence of PTH. Statistical analysis compared mean axial craniectomy margin distance from midline in patients with versus without PTH. Distances from midline were tested as potential thresholds. No significant difference was identified in mean axial craniectomy margin distance from midline in patients developing PTH compared with patients with no PTH (n = 24, 12.8 mm versus n = 356, 16.6 mm respectively, p = 0.086). No significant cutoff distance from midline was identified (n = 212, p = 0.201). This study, the largest to date, was unable to identify a threshold with sufficient discrimination to support clinical recommendations in terms of DC margins with regard to midline, including thresholds reportedly significant in previously published research.

Abstract
OBJECTIVE Decompressive craniectomy (DC) relieves intracranial hypertension after severe traumatic brain injury (TBI), but it has been associated with poor clinical outcome in 2 recent randomized controlled trials. In this study, we investigated the incidence and explanatory variables for DC-related and cranioplasty (CP)-related complications after TBI. METHODS In this retrospective study, we identified 61 patients with TBI who were treated with DC in the neurointensive care unit, Uppsala University Hospital, Sweden, between 2008 and 2018. Demography, admission status, radiology, and clinical outcome were analyzed. RESULTS Eleven patients (18%) were reoperated because of postoperative hemorrhage after DC. Six (10%) developed postoperative infection during neurointensive care. Twenty-eight (46%) developed subdural hygromas and 10 (16%) received a permanent cerebrospinal fluid shunt. Sixteen patients (26%) died before CP. Median time to CP was 7 months (range, 2-19 months) and 32 (71%) were operated on with autologous bone and 13 (29%) with synthetic material primarily. In 9 patients with autologous bone (29%), the CP had to be replaced because of bone resorption/infection, whereas this did not occur after synthetic material (P = 0.04). However, all 4 postoperative hemorrhages after CP occurred when synthetic material was used (P = 0.005). CONCLUSIONS DC and CP surgery have a high risk for complications, leading to additional neurosurgery in about one third of cases. Synthetic CP materials may decrease the risk of reoperation, but special care with hemostasis is required because of increased risk of postoperative hemorrhage. Future trials need to address these topics to further improve the outcome for these patients.

Abstract
Subdural hygroma (SDG) represents a common complication following decompressive craniectomy (DC). To our knowledge we present the first meta-analysis investigating the role of clinical and technical factors in the development of SDG after DC for traumatic brain injury. We further investigated the impact of SDG on the final prognosis of patients. The systematic review of the literature was done according to the PRISMA guidelines. Two different online medical databases (PubMed/Medline and Scopus) were screened. Four articles were included in this meta-analysis. Data regarding age, sex, trauma dynamic, Glasgow Coma Scale (GCS), pupil reactivity and CT scan findings on admission were collected for meta-analysis in order to evaluate the possible role in the SDG formation. Moreover we studied the possible impact of SDG on the outcome by evaluating the rate of patients dead at final follow-up and the Glasgow Outcome Scale (GOS) at final follow-up. Among the factors available for meta-analysis only the basal cistern involvement on CT scan was associated with the development of a SDG after DC (p < 0.001). Moreover, patients without SDG had a statistically significant better outcome compared with patients who developed SDG after DC in terms of GOS (p < 0.001). The rate of patients dead at follow-up was lower in the group of patients without SDH (8.25%) compared with patients who developed SDG (11.51%). SDG after DC is a serious complication affecting the prognosis of patients. Further studies are needed to define the role of some adjustable technical aspect of DC in preventing such a complication.

Prognostic significance of subdural hygroma for post-traumatic hydrocephalus after decompressive craniectomy in the traumatic brain injury setting: a systematic review and meta-analysis. Neurosurg Rev 2019; 44:129-138.

Abstract
Post-traumatic hydrocephalus (PTH) is a potentially morbid sequela of decompressive craniectomy for traumatic brain injury (TBI). Subdural hygromas are commonly identified following decompressive craniectomy, but the clinical relevance and predictive relationship with PTH in this patient cohort is not completely understood. Survey of seven electronic databases from inception to June 2019 was conducted following PRISMA guidelines. Articles were screened against pre-specified criteria. Multivariate hazard ratios (HRs) for PTH by the presence of subdural hygroma were extracted and pooled by meta-analysis of proportions with random effects modeling. We systematically identified nine pertinent studies describing outcomes of 1010 TBI patients managed by decompressive craniectomy. Of the overall cohort, there were 211 (21%) females and median age was 37.5 years (range 33-53). On presentation, median Glasgow Coma Scale was 7 (range, 5-8). In sum, PTH was reported in 228/840 (27%) cases, and subdural hygroma was reported in 449/1010 (44%) cases across all studies. Pooling multivariate-derived HRs indicated that subdural hygroma was a significant, independent predictor of PTH (HR, 7.1; 95% CI, 3.3-15.1). The certainty of this association was deemed low due to heterogeneity concerns. The presence of subdural hygroma is associated with increased risk of PTH after decompressive craniectomy among TBI patients based on the current literature and may mandate closer clinical surveillance when detected. Prospective studies, including those of intracranial hydrodynamics following decompressive craniectomy in the setting of TBI, will better validate the certainty of these findings.

Abstract
Decompressive craniectomy (DC) has become the definitive surgical procedure to manage medically intractable rise in intracranial pressure due to stroke and traumatic brain injury. With incoming evidence from recent multi-centric randomized controlled trials to support its use, we could expect a significant rise in the number of patients who undergo this procedure. Although one would argue that the procedure reduces mortality only at the expense of increasing the proportion of the severely disabled, what is not contested is that patients face the risk of a large number of complications after the operation and that can further compromise the quality of life. Decompressive craniectomy (DC), which is designed to overcome the space constraints of the Monro Kellie doctrine, perturbs the cerebral blood, and CSF flow dynamics. Resultant complications occur days to months after the surgical procedure in a time pattern that can be anticipated with advantage in managing them. New or expanding hematomas that occur within the first few days can be life-threatening and we recommend CT scans at 24 and 48 h postoperatively to detect them. Surgeons should also be mindful of the myriad manifestations of peculiar complications like the syndrome of the trephined and neurological deterioration due to paradoxical herniation which may occur many months after the decompression. A sufficiently large frontotemporoparietal craniectomy, 15 cm in diameter, increases the effectiveness of the procedure and reduces chances of external cerebral herniation. An early cranioplasty, as soon as the brain is lax, appears to be a reasonable choice to mitigate many of the late complications. Complications, their causes, consequences, and measures to manage them are described in this chapter.

Abstract
In severe traumatic brain injury (TBI), contusions often are worsened by contusion expansion or hemorrhagic progression of contusion (HPC), which may double the original contusion volume and worsen outcome. In humans and rodents with contusion-TBI, sulfonylurea receptor 1 (SUR1) is upregulated in microvessels and astrocytes, and in rodent models, blockade of SUR1 with glibenclamide reduces HPC. SUR1 does not function by itself, but must co-assemble with either KIR6.2 or transient receptor potential cation channel subfamily M member 4 (TRPM4) to form KATP (SUR1-KIR6.2) or SUR1-TRPM4 channels, with the two having opposite effects on membrane potential. Both KIR6.2 and TRPM4 are reportedly upregulated in TBI, especially in astrocytes, but the identity and function of SUR1-regulated channels post-TBI is unknown. Here, we analyzed human and rat brain tissues after contusion-TBI to characterize SUR1, TRPM4, and KIR6.2 expression, and in the rat model, to examine the effects on HPC of inhibiting expression of the three subunits using intravenous antisense oligodeoxynucleotides (AS-ODN). Glial fibrillary acidic protein (GFAP) immunoreactivity was used to operationally define core versus penumbral tissues. In humans and rats, GFAP-negative core tissues contained microvessels that expressed SUR1 and TRPM4, whereas GFAP-positive penumbral tissues contained astrocytes that expressed all three subunits. Förster resonance energy transfer imaging demonstrated SUR1-TRPM4 heteromers in endothelium, and SUR1-TRPM4 and SUR1-KIR6.2 heteromers in astrocytes. In rats, glibenclamide as well as AS-ODN targeting SUR1 and TRPM4, but not KIR6.2, reduced HPC at 24 h post-TBI. Our findings demonstrate upregulation of SUR1-TRPM4 and KATP after contusion-TBI, identify SUR1-TRPM4 as the primary molecular mechanism that accounts for HPC, and indicate that SUR1-TRPM4 is a crucial target of glibenclamide.

Abstract
BACKGROUND Acute subdural hematoma represents an important cause of disability and mortality. Its surgical treatment takes advantage of two surgical procedures: craniotomy and decompressive craniectomy, nevertheless the effectiveness of one procedure rather than the other is still debated. This study was conducted to identify which of the surgical procedures could provide better neurological outcome after traumatic acute subdural hematoma; as a secondary endpoint, the study tries to settle pre-operative prognostic factors useful to identify the most appropriate surgical technique for every specific patient and kind of trauma. METHODS A retrospective analysis was performed on patients who underwent craniotomy or decompressive craniectomy between January 2010 and July 2017 at the Department of Neurosurgery of Umberto I Hospital in Rome. Ninty-four patients were selected and reviewing clinical records, pre-operative and post-operative's data were collected (e.g. GCS, mechanism of trauma, CT findings, mortality rate, neurological outcome at discharge, mRS at 12 months). Data were analyzed using X2 test and the F test. The multivariate analysis was performed using a stepwise logistic regression. The analysis was carried out using SPSS software and a p value ≤ 0.05 was considered significant. RESULTS On 94 patients 46.8% underwent decompressive craniectomy and 53.2% underwent craniotomy. The mortality rate was (53.2%); it was shown to be related to a GCS < 8 (p = 0.033) and to age > 60 years old (p = 0.0001). Decompressive craniectomy was performed most frequently for high energy trauma (p =0.006); the mean GCS at admission was 7.91 for decompressive craniectomy and 9.64 for craniotomy (p = 0.05). Patients who underwent decompressive craniectomy and survived surgery showed a better neurological outcome compared to those who underwent craniotomy (p = 0.009). The evaluation of mRS after 12 months didn't show a statistically significant difference between the two groups. CONCLUSIONS In case of high energy trauma and GCS ≤8 different neurosurgeons decided to perform most frequently decompressive craniectomy rather than craniotomy. Furthermore, even if not related to survival rate, decompressive craniectomy showed a better neurological outcome especially in patients with GCS ≤8 at admission. In conclusion, even if prospective studies are required, these results depict the current attitude about the choice between craniotomy and decompressive craniectomy.

Abstract
BACKGROUND Decompressive craniotomy (DC) is a known risk factor for the development of posttraumatic hydrocephalus (PTH) in the patients with traumatic brain injury (TBI). Herein, the present study reported the development of PTH requiring ventriculoperitoneal (VP) shunt after DC for TBI. METHODS Four databases (PubMed, Web of Science, Scopus, and Cochrane Library) were searched from 1983 to April 2018. The studies evaluating the prevalence of PTH requiring VP shunt after DC in the patients with TBIwere selected without language restriction. A random-effects meta-analysis using event rate (ER) and 95% confidence intervals(CIs), was runby RevMan5.3 software. RESULTS Out of 355 studies obtained from the databases, 25 studies were included and analyzed in the meta-analysis. The studies included 2402 patients undergoing DC for TBI, 354 of whohad PTH. The pooled ER of hydrocephalus in the patients undergoing DC for TBI was 17.7% [95%CI: 13.2 to 23.4%; P<0.001]. In addition, the pooled analysis showed that ER of hydrocephalus was 13% in adults [95%CI: 9 to 18.5%; P<0.001] and 37.6% in children [95%CI: 27.79 to 48.7%; P=0.029; I2=0%]. CONCLUSION The present study demonstrated that DC after TBI was associated with the development of PTH, especially in children compared to adults.

Abstract
Background Temporal hollowing is inevitable after decompressive craniectomy. This complication affects self-perception and quality of life, and various techniques and materials have therefore been used to restore patients’ confidence. Autologous fat grafting in postoperative scar tissue has been considered challenging because of the hostile tissue environment. However, in this study, we demonstrate that autologous fat grafting can be a simple and safe treatment of choice, even for postoperative depressed temporal scar tissue. Methods Autologous fat grafting was performed in 13 patients from 2011 to 2016. Fat was harvested according to Coleman’s strategy, using a tumescent technique. Patient-reported outcomes were collected preoperatively and at 1-month and 1-year follow-ups. Photographs were taken at each visit. Results The thighs were the donor site in all cases for the first procedure. The median final volume of harvested fat was 29.4 mL (interquartile range [IQR], 24.0–32.8 mL). The median final volume of fat transferred into the temporal area was 4.9 mL on the right side (IQR, 2.5–7.1 mL) and 4.6 mL on the left side (IQR, 3.7–5.9 mL). There were no major complications. The patient-reported outcomes showed significantly improved self-perceptions at 1 month and at 1 year. Conclusions Despite concerns about the survival of grafted fat in scar tissue, we advise autologous fat grafting for patients with temporal hollowing resulting from a previous craniectomy.

Abstract
Decompressive craniectomy (DC) has been used for many years in the management of patients with elevated intracranial pressure and cerebral edema. Ongoing clinical trials are investigating the clinical and cost effectiveness of DC in trauma and stroke. While DC has demonstrable efficacy in saving life, it is accompanied by a myriad of non-trivial complications that have been inadequately highlighted in prospective clinical trials. Missing from our current understanding is a comprehensive analysis of all potential complications associated with DC. Here, we review the available literature, we tabulate all reported complications, and we calculate their frequency for specific indications. Of over 1500 records initially identified, a final total of 142 eligible records were included in our comprehensive analysis. We identified numerous complications related to DC that have not been systematically reviewed. Complications were of three major types: (1) Hemorrhagic (2) Infectious/Inflammatory, and (3) Disturbances of the CSF compartment. Complications associated with cranioplasty fell under similar major types, with additional complications relating to the bone flap. Overall, one of every ten patients undergoing DC may suffer a complication necessitating additional medical and/or neurosurgical intervention. While DC has received increased attention as a potential therapeutic option in a variety of situations, like any surgical procedure, DC is not without risk. Neurologists and neurosurgeons must be aware of all the potential complications of DC in order to properly advise their patients.

Abstract
OBJECT
Rotterdam CT scoring is a CT classification system for grouping patients with traumatic brain injury (TBI) based on multiple CT characteristics. This retrospective study aimed to determine the relationship between initial or preoperative Rotterdam CT scores and TBI prognosis after decompressive craniectomy (DC).
METHODS
The authors retrospectively reviewed the medical records of all consecutive patients who underwent DC for nonpenetrating TBI in 2 hospitals from January 2006 through December 2013. Univariate and multivariate logistic regression and receiver operating characteristic (ROC) curve analyses were used to determine the relationship between initial or preoperative Rotterdam CT scores and mortality at 30 days or Glasgow Outcome Scale (GOS) scores at least 3 months after the time of injury. Unfavorable outcomes were GOS Scores 1–3 and favorable outcomes were GOS Scores 4 and 5.
RESULTS
A total of 48 cases involving patients who underwent DC for TBI were included in this study. Univariate analyses showed that initial Rotterdam CT scores were significantly associated with mortality and both initial and preoperative Rotterdam CT scores were significantly associated with unfavorable outcomes. Multivariable logistic regression analysis adjusted for established predictors of TBI outcomes showed that initial Rotterdam CT scores were significantly associated with mortality (OR 4.98, 95% CI 1.40–17.78, p = 0.01) and unfavorable outcomes (OR 3.66, 95% CI 1.29–10.39, p = 0.02) and preoperative Rotterdam CT scores were significantly associated with unfavorable outcomes (OR 15.29, 95% CI 2.50–93.53, p = 0.003). ROC curve analyses showed cutoff values for the initial Rotterdam CT score of 5.5 (area under the curve [AUC] 0.74, 95% CI 0.59–0.90, p = 0.009, sensitivity 50.0%, and specificity 88.2%) for mortality and 4.5 (AUC 0.71, 95% CI 0.56–0.86, p = 0.02, sensitivity 62.5%, and specificity 75.0%) for an unfavorable outcome and a cutoff value for the preoperative Rotterdam CT score of 4.5 (AUC 0.81, 95% CI 0.69–0.94, p < 0.001, sensitivity 90.6%, and specificity 56.2%) for an unfavorable outcome.
CONCLUSIONS
Assessment of changes in Rotterdam CT scores over time may serve as a prognostic indicator in TBI and can help determine which patients require DC.

Abstract
BACKGROUND For cases of severe traumatic brain injury, during primary operation, neurosurgeons usually face a dilemma of whether or not to remove the bone flap after mass lesion evacuation. Decompressive craniectomy, which involves expansion of fixed cranial cavity, is used to treat intra-operative brain swelling and post-operative malignant intracranial hypertension. However, due to indefinite indication, the decision to perform this procedure heavily relies on personal experiences. In addition, decompressive craniectomy is associated with various complications, and the procedure lacks strong evidence of better outcomes. In the present study, we designed a prospective, randomized, controlled trial to clarify the effect of decompressive craniectomy in severe traumatic brain injury patients with mass lesions. METHODS PRECIS is a prospective, randomized, assessor-blind, single center clinical trial. In this trial, 336 patients with traumatic mass lesions will be randomly allocated to a therapeutic decompressive craniectomy group or a prophylactic decompressive craniectomy group. In the therapeutic decompressive craniectomy group, the bone flap will be removed or replaced depending on the emergence of brain swelling. In the prophylactic decompressive craniectomy group, the bone flap will be removed after mass lesion evacuation. A stepwise management of intracranial pressure will be provided according to the Brain Trauma Foundation guidelines. Salvage decompressive craniectomy will be performed for craniotomy patients once there is evidence of imaging deterioration and post-operative malignant intracranial hypertension. Participants will be assessed at 1, 6 and 12 months after randomization. The primary endpoint is favorable outcome according to the Extended Glasgow Outcome Score (5-8) at 12 months. The secondary endpoints include quality of life measured by EQ-5D, mortality, complications, intracranial pressure and cerebral perfusion pressure control and incidence of salvage craniectomy in craniotomy patients at each investigation time point. DISCUSSION This study will provide evidence to optimize primary decompressive craniectomy application and assess outcomes and risks for mass lesions in severe traumatic brain injury.

The value of intraoperative intracranial pressure monitoring for predicting re-operation using salvage decompressive craniectomy after craniotomy in patients with traumatic mass lesions. BMC Surg 2015; 15:111. [PMID: 26467905 PMCID: PMC4605088 DOI: 10.1186/s12893-015-0100-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2015] [Accepted: 10/10/2015] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND The risk factors of predicting the need for postoperative decompressive craniectomy due to intracranial hypertension after primary craniotomy remain unclear. This study aimed to investigate the value of intraoperative intracranial pressure (ICP) monitoring in predicting re-operation using salvage decompressive craniectomy (SDC). METHODS From January 2008 to October 2014, we retrospectively reviewed 284 patients with severe traumatic brain injury (STBI) who underwent craniotomy for mass lesion evacuation without intraoperative brain swelling. Intraoperative ICP was documented at the time of initial craniotomy and then again after the dura was sutured. SDC was used when postoperative ICP was continually higher than 25 mmHg for 1 h without a downward trend. Univariate and multivariate analyses were applied to both initial demographic and radiographic features to identify risk factors of SDC requirement. RESULTS Of 284, 41 (14.4%) patients who underwent SDC had a higher Initial ICP than those who didn't (38.1 ± 9.2 vs. 29.3 ± 8.1 mmHg, P < 0.001), but there was no difference in ICP after the dura was sutured. The factors which have significant effects on SDC are higher initial ICP [odds ratio (OR): 1.100, 95% confidence interval (CI): 1.052-1.151, P < 0.001], older age (OR: 1.039, 95% CI: 1.002-1.077, P = 0.039), combined lesions (OR: 3.329, 95% CI: 1.199-9.244, P = 0.021) and early hypotension (OR: 2.524, 95% CI: 1.107-5.756, P = 0.028). The area under the curve of multivariate regression model was 0.771. CONCLUSIONS The incidence of re-operation using SDC after craniotomy was 14.4%. The independent risk factors of SDC requirement are initial ICP, age, early hypotension and combined lesions.

Abstract
Increased intracranial pressure (ICP) secondary to severe brain injury is common. Increased ICP is commonly encountered in malignant middle cerebral artery ischemic stroke, traumatic brain injury, subarachnoid hemorrhage, and intracerebral hemorrhage. Multiple interventions-both medical and surgical-exist to manage increased ICP. Medical management is used as first-line therapy; however, it is not always effective and is associated with significant risks. Decompressive hemicraniectomy is a surgical option to reduce ICP, increase cerebral compliance, and increase cerebral blood perfusion when medical management becomes insufficient. The purpose of this review is to provide an up-to-date summary of the use of decompressive hemicraniectomy for the management of refractory elevated ICP in malignant middle cerebral artery ischemic stroke, traumatic brain injury, subarachnoid hemorrhage, and intracerebral hemorrhage.

Abstract
The aim of this study was to review all post-craniectomy cranioplasties performed in a single institution, with an emphasis on procedure-related complications and risk factor analysis. Post-craniectomy cranioplasty is known to be associated with significant complications. Previous studies on predictors of complications have yielded conflicting results. We conducted a retrospective study on prospectively collected data on all cranioplasties done between 1 January 2003 and 31 December 2012. Multivariate analysis was performed to interrogate potential risk factors predisposing to procedure-related complications. Of the 162 procedures, the overall complication rate was 16.7%. Infection and flap depression occurred in 13 (8%) and five patients (3.1%), respectively. These led to reoperations in 12 patients. The presence of a ventriculoperitoneal shunt during cranioplasty was the only significant factor associated with a higher rate of infection (28.6% versus 9.7%, p=0.001) and flap depression (14.3% versus 3.3%, p=0.03). Indications for the initial craniectomy, choice of graft materials and the time interval between craniectomy and cranioplasty had no significant association with complications. The presence of ventriculoperitoneal shunt at the time of cranioplasty is a significant risk factor for cranioplasty complications. Early cranioplasty is safe. Whether temporizing lumbar or external ventricular drainage is a better alternative to shunting in patients who are drainage-dependent at the time of cranioplasty remain to be determined.

Abstract
Introduction: Decompressive craniectomy (DC) has increasing support with current studies suggesting an improvement in both survival rates and outcomes with this intervention. However, questions surround this procedure; specifically, no evidence has indicated the optimal craniectomy size. Larger craniectomy is thought to better decrease intracranial pressure, but with a possible increase in complication rates. Our hypothesis is that a larger craniectomy may improve mortality and outcome, but may increase complication rates. Materials and Methods: A retrospective observational therapeutic study was undertaken to determine if craniectomy size is related to complication rates, mortality, or outcome. Our institution's Trauma Registry was searched for patients undergoing DC. Craniectomy size was measured by antero-posterior (AP) diameter. Mortality, outcome (through admission and discharge Glasgow Coma Score and Glasgow Outcome Scale), and complications (such as re-bleeding, re-operation, hygroma, hydrocephalus, infection, and syndrome of the trephined) were noted. Complications, mortality, and outcome were then compared to craniectomy size, to determine if any relation existed to support our hypothesis. Results: 20 patients met criteria for inclusion in this study. Craniectomy size as measured by AP diameter was correlated with a statistically significant improvement in mortality within the group. All patients with a craniectomy size less than 10 cm died. However, outcome was not significantly related to craniectomy size in the group. Similarly, complication rates did not differ significantly compared to craniectomy size. Discussion: This study provides Level 3 evidence that craniectomy size may be significantly related to improved mortality within our group, supporting our initial hypothesis; however, no significant improvement in outcome was seen. Similarly, in contrast to our hypothesis, complication rates did not significantly correlate with craniectomy size.

Abstract
Object
Mass lesions from traumatic brain injury (TBI) often require surgical evacuation as a life-saving measure and to improve outcomes, but optimal timing and surgical technique, including decompressive craniectomy, have not been fully defined. The authors compared neurosurgical approaches in the treatment of TBI at 2 academic medical centers to document variations in real-world practice and evaluate the efficacies of different approaches on postsurgical course and long-term outcome.
Methods
Patients 18 years of age or older who required neurosurgical lesion evacuation or decompression for TBI were enrolled in the Co-Operative Studies on Brain Injury Depolarizations (COSBID) at King's College Hospital (KCH, n = 27) and Virginia Commonwealth University (VCU, n = 24) from July 2004 to March 2010. Subdural electrode strips were placed at the time of surgery for subsequent electrocorticographic monitoring of spreading depolarizations; injury characteristics, physiological monitoring data, and 6-month outcomes were collected prospectively. CT scans and medical records were reviewed retrospectively to determine lesion characteristics, surgical indications, and procedures performed.
Results
Patients enrolled at KCH were significantly older than those enrolled at VCU (48 vs 34 years, p < 0.01) and falls were more commonly the cause of TBI in the KCH group than in the VCU group. Otherwise, KCH and VCU patients had similar prognoses, lesion types (subdural hematomas: 30%–35%; parenchymal contusions: 48%–52%), signs of mass effect (midline shift ≥ 5 mm: 43%–52%), and preoperative intracranial pressure (ICP). At VCU, however, surgeries were performed earlier (median 0.51 vs 0.83 days posttrauma, p < 0.05), bone flaps were larger (mean 82 vs 53 cm2, p < 0.001), and craniectomies were more common (performed in 75% vs 44% of cases, p < 0.05). Postoperatively, maximum ICP values were lower at VCU (mean 22.5 vs 31.4 mm Hg, p < 0.01). Differences in incidence of spreading depolarizations (KCH: 63%, VCU: 42%, p = 0.13) and poor outcomes (KCH: 54%, VCU: 33%, p = 0.14) were not significant. In a subgroup analysis of only those patients who underwent early (< 24 hours) lesion evacuation (KCH: n = 14; VCU: n = 16), however, VCU patients fared significantly better. In the VCU patients, bone flaps were larger (mean 85 vs 48 cm2 at KCH, p < 0.001), spreading depolarizations were less common (31% vs 86% at KCH, p < 0.01), postoperative ICP values were lower (mean: 20.8 vs 30.2 mm Hg at KCH, p < 0.05), and good outcomes were more common (69% vs 29% at KCH, p < 0.05). Spreading depolarizations were the only significant predictor of outcome in multivariate analysis.
Conclusions
This comparative-effectiveness study provides evidence for major practice variation in surgical management of severe TBI. Although ages differed between the 2 cohorts, the results suggest that a more aggressive approach, including earlier surgery, larger craniotomy, and removal of bone flap, may reduce ICP, prevent cortical spreading depolarizations, and improve outcomes. In particular, patients requiring evacuation of subdural hematomas and contusions may benefit from decompressive craniectomy in conjunction with lesion evacuation, even when elevated ICP is not a factor in the decision to perform surgery.

Abstract
OBJECTIVE Decompressive craniectomy (DC) is one of the most ardently debated topics in traumatic brain injury (TBI) treatment. The aim of this study is to compare the differences between DC with and without mass evacuation in patients with TBI. METHODS From January 2005 to December 2009, 164 patients underwent DC at our centre. Seventy-one of the 164 patients underwent DC for diffuse injury (group B). Ninety-three patients underwent DC as part of an operation to treat a mass lesion (group A). Patient characteristics and post-operative outcomes were compared between the two groups. RESULTS Thirty-six patients died during this study (22.0%). Fifty-nine of these patients (36.0%) remained either vegetative (n = 30) or severely disabled (n = 29). Sixty-nine patients (42%) had a Glasgow Outcome Scale (GOS) score of 4 to 5. Three predictors were significantly related to 60-day mortality: age older than 50 years (odds ratio [OR], 2.36; 95% confidence interval [CI], 1.01-5.52), abnormal pupillary response to light (OR, 3.79; 95% CI, 1.29-11.14), and DC with mass evacuation (OR, 0.31; 95% CI, 0.12-0.79). Mortality differed substantially between patients with (group A) and without (group B) mass evacuation (14.0% versus 32.4%). Only one predictor was significantly related to good outcome: Glasgow Coma Scale (GCS) score at admission: (OR, 2.43; and 95% CI, 1.39-4.24). CONCLUSIONS DC for patients with or without mass lesion has different patient characteristics. DC with mass evacuation has lower mortality than DC without mass evacuation. Outcome prediction following DC should be adjusted according to mass evacuation.

Abstract
Decompressive craniectomy (DC) is a surgical practice that has been used since the late 19th century. The cerebral blood flow increase after the performance of a DC can delay and even prevent the development of cerebral circulatory arrest and brain death (BD). We aimed to determine the prevalence of BD, the use of DC, and the evolution to BD with versus without DC. This retrospective, observational, cross-sectional study was performed in a single high-intensity center in Argentina from January 2003 to December 2010. Inclusion criteria were all patients with Glasgow Coma Score of at most 7 on admission or during their stay in the intensive care units. Exclusion criteria were patients with incomplete data. In cases of death, we assessed whether they fulfilled BD criteria or if the cause of death was a cardiac arrest (CA). The 698 patients considered for analysis showed a 60% (n = 418) global mortality rate. The causes were: CA (n = 270); BD (n = 108) and others considered to be "undefined," namely not assessed completely for the diagnosis of BD (n = 40). According to diagnosis category, traumatic brain injury (TBI) was largest (nearly 50%). The DC group (n = 206) showed significant differences regarding sex and diagnosis category versus no DC group. Mortality was significantly lower in this group (48% versus 65%, P < .001). No significant differences were observed comparing causes of death (CA, BD, or undefined). The use of DC did not influence the frequency of BD development (24% versus 26%, P = .72). The average DC rate was 30% and of BD 16%. The prevalence of DC and better survival were recorded compared with subjects without DC. The prevalence of BD was lower than expected in accordance with national registries; however, among our group, DC did not seem to modify the evolution to BD.

Abstract
BACKGROUND The aim of this article was to review the clinical practice of "bone flap decompression" in Regional Neurosurgical Units with no particular protocol in use. METHODS From January 2005 to December 2008, a retrospective and multicentre study was conducted on patients who were treated with decompressive craniectomy (DC) in seven departments of neurosurgery in Italy. This study included patients with traumatic brain injury, stroke, aneurysmal subarachnoid haemorrhage and cerebral arteriovenous malformations. Data were retrieved from individual medical records. RESULTS We identified 526 patients with DC. Age was the most significant predictor factor of survival, together with pupil reactivity, time of decompression and size of the bone flap. The effect of age in predicting survival was so important that in patients over 65 years old we did not find any other significant factor related to survival. In younger patients, the survival rate was much better with a large bone flap (p = 0.01). Unfortunately, 57% of patients were decompressed with a bone flap of less than 12 cm in diameter. This was probably due to the association in 80% of cases between haematoma evacuation and decompression. CONCLUSIONS The current practice in many centres is different from published papers. Decompression is common over the age of 65 years, is associated with haematoma evacuation and often the bone flaps are inadequate in terms of size.

Abstract
The management of severe traumatic brain injury (TBI) focuses on prevention and treatment of secondary insults such as cerebral hypoxia (CH). There are a number of biomarkers that are thought to play a part in secondary injury following severe TBI. This study evaluates the association between S100β, neuron-specific enolase (NSE), and glial fibrillary acidic protein (GFAP), detected in the serum of severe TBI patients and CH as measured by brain tissue oxygen partial pressure (Pbo(2)). Patients with severe TBI were prospectively enrolled. Pressure times time (PTD; mm Hg*h), measuring the depth and duration of CH, was calculated for 12-h periods for episodes of moderate (Pbo(2) < 20 mm Hg) and severe (Pbo(2) < 15 mm Hg) CH, and compared to serum levels of S100β, NSE, and GFAP drawn prior to periods of monitoring. An adjusted mixed model analysis was applied as was receiver operating characteristic (ROC) curve analysis. Of 76 patients enrolled, 24 had Pbo(2) monitoring. One hundred and thirty serum samples were matched with 12-h periods of monitoring. Significant associations were found in adjusted analyses between increasing serum levels of S100β (coefficient=0.57, 0.56; p<0.001), NSE (coefficient=0.48, 0.52; p<0.001), and GFAP (coefficient=0.29, 0.30; p=0.003 and 0.002), and increasing PTD of moderate (Pbo(2)<20 mm Hg) and severe (Pbo(2)<15 mm Hg) CH. AUCs for the prediction of moderate and severe CH were 0.62 and 0.66 for S100β, 0.55 and 0.71 for NSE, and 0.50 and 0.62 for GFAP, respectively. Specificities were between 76% and 90% for S100β and NSE. S100β, NSE, and GFAP demonstrate promise as candidate serum markers of impending CH. The fact that these biomarker elevations occur prior to the onset of clinical manifestations suggests that we may be able to predict imminent events following TBI. Given the morbidity of CH, early intervention and prevention may have a significant impact on outcomes and help guide decisions about the timing of interventions.

Abstract
OBJECTIVE The aim of this study was to evaluate the incidence of hydrocephalus and understand the influence of hydrocephalus on the functional outcome of patients undergoing decompressive craniectomy for malignant middle cerebral artery (MCA) infarction. METHODS We retrospectively analyzed data of consecutive patients who underwent decompressive craniectomy for malignant MCA infarction. Clinical and imaging data were reviewed to confirm the incidence of hydrocephalus and evaluate the impact of hydrocephalus on functional outcome. The functional outcomes of patients were estimated with the Glasgow outcome score at 1year after stroke onset. RESULTS Seventeen patients who received decompressive craniectomy for malignant MCA infarction from January 2003 to December 2006 were enrolled. Persistent hydrocephalus developed in 5 patients. The functional outcomes in these patients were uniformly poor regardless of cerebrospinal fluid diversion surgery. Our data revealed that functional outcome was related to patient age and the duration from infarction to craniectomy. CONCLUSIONS Persistent hydrocephalus is common in patients who receive decompressive craniectomy for malignant MCA infarction. However, the shunt procedure does not significantly improve the patient's clinical condition. The timing of operation in relation to the functional outcome may be critical.

Abstract
The magnitude of damage to cerebral tissues following head trauma is determined by the primary injury, caused by the kinetic energy delivered at the time of impact, plus numerous secondary injury responses that almost inevitably worsen the primary injury. When head trauma results in a cerebral contusion, the hemorrhagic lesion often progresses during the first several hours after impact, either expanding or developing new, non-contiguous hemorrhagic lesions, a phenomenon termed hemorrhagic progression of a contusion (HPC). Because a hemorrhagic contusion marks tissues with essentially total unrecoverable loss of function, and because blood is one of the most toxic substances to which the brain can be exposed, HPC is one of the most severe types of secondary injury encountered following traumatic brain injury (TBI). Historically, HPC has been attributed to continued bleeding of microvessels fractured at the time of primary injury. This concept has given rise to the notion that continued bleeding might be due to overt or latent coagulopathy, prompting attempts to normalize coagulation with agents such as recombinant factor VIIa. Recently, a novel mechanism was postulated to account for HPC that involves delayed, progressive microvascular failure initiated by the impact. Here we review the topic of HPC, we examine data relevant to the concept of a coagulopathy, and we detail emerging data elucidating the mechanism of progressive microvascular failure that predisposes to HPC after head trauma.

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: Although a relatively simple procedure, cranioplasties have been associated with high complication rates. Keeping this in perspective, we aimed to determine the factors associated with immediate and long-term complications of cranioplasties at our institution. Methods: A retrospective review of patient records was carried out for patients having undergone reconstructive cranioplasties at our institution during the last 10 years (2001-2010). All case notes, records, and investigations were reviewed and the data were recorded in a predesigned questionnaire. Complications were recorded along with existing comorbids and measures taken for their prevention and management. Univariate and multivariate logistic regression analysis was performed to determine possible predictors of complications. Results: A total of 96 patients with a mean age of 33 + 15 years were included in the study. Of the sample, 76% (n = 73) had no comorbids. The leading primary pathology was blunt traumatic brain injuries in 46% (n = 44), followed by cerebrovascular incidents in 24% (n = 23), penetrating traumatic brain injuries in 12% (n = 11), and tumors in 10% (n = 10) of cases, with 41% (n = 39) of patients requiring multiple craniotomies. In a mean follow-up of 386 ± 615 days, complications were noted in 36.5% (n = 35) of the patients. Twenty six percent of patients (n = 25) had minor complications which included breakthrough seizures (15.6%, n = 15), subgaleal collections (3.1%, n = 3), and superficial wound infections (3.1%, n = 3), whereas major complications (10.4% n = 10) included hydrocephalus (3.1%, n = 3), transient neurological deficits (3.1%, n = 3), and osteomyelitis (2.1%, n = 2). Univariate and multivariate analysis revealed External Ventricular Drain (EVD) placement and parietal flaps to be associated with complications. This could be explained by the fact that the patients requiring EVD usually have relatively severe head injuries, increasing the possibility of hydrocephalus. Conclusion: We have found a higher risk of complications of cranioplasty in patients who had EVD placement and removal prior to their constructive surgery. We however did not find any association between risks of complications in any other studied variable. We also did not find any association between intraoperative placement of subgaleal drains and postoperative risk of subgaleal fluid collections. Overall, our results are comparable with other reported series on cranioplasties.

Abstract
OBJECT The aim of this study was to determine the incidence of posttraumatic hydrocephalus in severely head-injured patients who required decompressive craniectomy (DC). Additional objectives were to determine the relationship between hydrocephalus and several clinical and radiological features, with special attention to subdural hygromas as a sign of distortion of the CSF circulation. METHODS The authors conducted a retrospective study of 73 patients with severe head injury who required DC. The patients were admitted to the authors' department between January 2000 and January 2006. Posttraumatic hydrocephalus was defined as: 1) modified frontal horn index greater than 33%, and 2) the presence of Gudeman CT criteria. Hygromas were diagnosed based on subdural fluid collection and classified according to location of the craniectomy. RESULTS Hydrocephalus was diagnosed in 20 patients (27.4%). After uni- and multivariate analysis, the presence of interhemispheric hygromas (IHHs) was the only independent prognostic factor for development of posttraumatic hydrocephalus (p<0.0001). More than 80% of patients with IHHs developed hydrocephalus within the first 50 days of undergoing DC. In all cases the presence of hygromas preceded the diagnosis of hydrocephalus. The IHH predicts the development of hydrocephalus after DC with 94% sensitivity and 96% specificity. The presence of an IHH showed an area under the receiver-operator characteristic of 0.951 (95% CI 0.87-1.00; p<0.0001). CONCLUSIONS Hydrocephalus was observed in 27.4% of the patients with severe traumatic brain injury who required DC. The presence of IHHs was a predictive radiological sign of hydrocephalus development within the first 6 months of DC in patients with severe head injury.

Abstract
Introduction Acute post-traumatic brain swelling (BS) is one of the pathological forms that need emergent treatment following traumatic brain injury. There is controversy about the effects of craniotomy on acute post-traumatic BS. The aim of the present clinical study was to assess the efficacy of unilateral decompressive craniectomy (DC) or unilateral routine temporoparietal craniectomy on patients with unilateral acute post-traumatic BS. Methods Seventy-four patients of unilateral acute post-traumatic BS with midline shifting more than 5 mm were divided randomly into two groups: unilateral DC group (n = 37) and unilateral routine temporoparietal craniectomy group (control group, n = 37). The vital signs, the intracranial pressure (ICP), the Glasgow outcome scale (GOS), the mortality rate and the complications were prospectively analysed. Results The mean ICP values of patients in the unilateral DC group at hour 24, hour 48, hour 72 and hour 96 after injury were much lower than those of the control group (15.19 +/- 2.18 mmHg, 16.53 +/- 1.53 mmHg, 15.98 +/- 2.24 mmHg and 13.518 +/- 2.33 mmHg versus 19.95 +/- 2.24 mmHg, 18.32 +/- 1.77 mmHg, 21.05 +/- 2.23 mmHg and 17.68 +/- 1.40 mmHg, respectively). The mortality rates at 1 month after treatment were 27% in the unilateral DC group and 57% in the control group (p = 0.010). Good neurological outcome (GOS Score of 4 to 5) rates 1 year after injury for the groups were 56.8% and 32.4%, respectively (p = 0.035). The incidences of delayed intracranial hematoma and subdural effusion were 21.6% and 10.8% versus 5.4% and 0, respectively (p = 0.041 and 0.040). Conclusions Our data suggest that unilateral DC has superiority in lowering ICP, reducing the mortality rate and improving neurological outcomes over unilateral routine temporoparietal craniectomy. However, it increases the incidence of delayed intracranial hematomas and subdural effusion, some of which need secondary surgical intervention. These results provide information important for further large and multicenter clinical trials on the effects of DC in patients with acute post-traumatic BS. Trial registration ISRCTN14110527

Abstract
Object
This retrospective comparative cohort study was aimed at discovering the risk factors associated with subdural hygroma (SDG) following decompressive craniectomy (DC) to relieve intracranial hypertension in severe head injury.
Methods
Sixty-eight of 104 patients who had undergone DC during a 48-month period and survived > 30 days were eligible for this study. To assess the dynamics of subdural fluid collections, the authors compared CT scanning data from and the characteristics of 39 patients who had SDGs with the data in 29 patients who did not have hygromas. Variables significant in the appearance, evolution, and resolution of this complication were analyzed in a 36-week longitudinal study.
Results
The earliest imaging evidence of SDG was seen during the 1st week after DC. The SDG volume peaked between Weeks 3 and 4 post-DC and was gradually resolved by the 17th week. Among the mechanisms of injury, motor vehicle accidents were most often linked to the development of an SDG after DC (p < 0.0007), and falls were least often associated (p < 0.005). Moreover, patients with diffuse brain injury were more prone to this complication (p < 0.0299) than those with an evacuated mass (p < 0.0001). There were no statistically significant differences between patients with and without hygromas in terms of age, sex, Glasgow Coma Scale score, intraventricular and subarachnoid hemorrhage, levels of intracranial pressure and cerebral perfusion pressure, timing of decompression, and the need for CSF diversion. More than 90% of the SDGs were ipsilateral to the side of the craniectomy, and 3 (8%) of 39 SDGs showed evidence of internal bleeding at ~ 8 weeks postinjury. Surgical evacuation was needed in 4 patients with SDGs.
Conclusions
High dynamic accidents and patients with diffuse injury were more prone to SDGs. Close to 8% of SDGs converted themselves into subdural hematomas at ~ 2 months postinjury. Although SDGs developed in 39 (~ 60%) of 68 post-DC patients, surgical evacuation was needed in only 4.
