RESUMO
INTRODUCTION: Rates of decompressive craniectomy (DC) in acute ischemic stroke (AIS) have been reported to decline over time, attributed to an increase in endovascular therapy (EVT) preventing the development of malignant cerebral edema. We sought to characterize trends in DC in AIS between 2011 and 2020. MATERIAL AND METHODS: We performed a retrospective observational study of U.S. AIS hospitalizations using the National Inpatient Sample, 2011 to 2020. We calculated rates of DC per 10,000 AIS among all AIS hospitalizations, as well as AIS hospitalizations undergoing invasive mechanical ventilation (IMV). A logistic regression to determine predictors of DC was performed. RESULTS: Of â¼4.4 million AIS hospitalizations, 0.5 % underwent DC; of â¼300,000 AIS with IMV, 5.8 % underwent DC. From 2011 to 2020, the rate of DC increased from 37.4 to 59.1 per 10,000 AIS (p < 0.001). The rate of DC in patients undergoing IMV remained stable at â¼550 per 10,000 (p = 0.088). The most important factors predicting DC were age (OR 4.88, 95 % CI 4.53-5.25), hospital stroke volume (OR 2.61, 95 % CI 2.17-3.14), hospital teaching status (OR 1.54, 95 % CI 1.36-1.75), and transfer status (OR 1.53, 95 % CI 1.41-1.66); EVT status did not predict DC. CONCLUSIONS: The rate of DC in AIS has increased between 2011 and 2020. Our findings are contrary to prior reports of decreasing DC rates over time. Increasing EVT rates do not seem to be preventing the occurrence of DC. Future research should focus on the decision-making process for both clinicians and surrogates regarding DC with consideration of long-term outcomes.

Cranioplasty (CP) is a standard procedure in neurosurgical practice for patients after (decompressive) craniectomy. However, CP surgery is not standardized, is carried out in different ways, and is associated with considerable complication rates. Here, we report our experiences with the use of different CP materials and analyze long-term complications and implant survival rates. We retrospectively studied patients who underwent CP surgery at our institution between 2004 and 2014. Binary logistic regression analysis was performed in order to identify risk factors for the development of complications. Kaplan-Meier analysis was used to estimate implant survival rates. A total of 392 patients (182 females, 210 males) with a mean age of 48 years were included. These patients underwent a total of 508 CP surgeries. The overall complication rate of primary CP was 33.2%, due to bone resorption/loosening (14.6%) and graft infection (7.9%) with a mean implant survival of 120 ± 5 months. Binary logistic regression analysis showed that young age (< 30 years) (p = 0.026, OR 3.150), the presence of multidrug-resistant bacteria (p = 0.045, OR 2.273), and cerebrospinal fluid (CSF) shunt (p = 0.001, OR 3.137) were risk factors for postoperative complications. The use of titanium miniplates for CP fixation was associated with reduced complication rates and bone flap osteolysis as well as longer implant survival rates. The present study highlights the risk profile of CP surgery. Young age (< 30 years) and shunt-dependent hydrocephalus are associated with postoperative complications especially due to bone flap autolysis. Furthermore, a rigid CP fixation seems to play a crucial role in reducing complication rates.

OBJECTIVES: Decompressive hemicraniectomy can be life-saving for malignant middle cerebral artery acute ischemic stroke (AIS). However, utilization and outcomes for hemicraniectomy in the US are not known. We sought to analyze baseline characteristics and outcomes of patients receiving hemicraniectomy for AIS in the US. MATERIALS AND METHODS: We identified adults who received hemicraniectomy for AIS, identified with validated International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9) code in the Nationwide Readmissions Database 2014. We calculated 30-day readmission rates, reasons for readmission, and procedures performed. RESULTS: 2850 of 531,896 AIS patients (0.54%) received hemicraniectomy. Although patients receiving hemicraniectomy were more likely to be younger (57.0, 95% CI 56.0-58.0; vs 70.9, 95% CI 70.6-71.2; p < 0.0001) and male (40% vs 51.2% female; p<0.0001), 46.3% of patients who received hemicraniectomy were age 60 years and older. Patients 60 years or older receiving hemicraniectomy were more likely to die (29.9% vs 21.9%, p = 0.0081). Hemicraniectomy was more frequently performed at large hospitals (75.3% vs 57.7%; p < 0.0001) in urban areas (99.1% vs 90.3%; p < 0.0001) designated as metropolitan teaching hospitals (88.3% vs 63.4%; p < 0.0001). 30-day readmissions were most commonly due to infection (31.5%), non-infectious medical complications (17.7%), and surgical complications (13.8%). These readmissions were critical. CONCLUSIONS: Although hemicraniectomy is used more frequently in the treatment of younger, male, ischemic stroke patients, only half of the patients receiving hemicraniectomy in 2014 were <60 years old. Regardless of age, hemicraniectomy is a geographically segregated procedure, only being performed in large metropolitan teaching hospitals.

BACKGROUND AND PURPOSE: Infarct volumes predict malignant infarcts in patients undergoing decompressive hemicraniectomy (DH) for large middle cerebral artery territory infarcts. The aim of the study was to determine the optimal magnetic resonance imaging infarct volume threshold that predicts a catastrophic outcome at 1 year (modified Rankin Scale score of 5 or death). METHODS: We included consecutive patients who underwent DH for large middle cerebral artery infarcts. We analyzed infarct volumes before DH with semi-automated methods on b1000 diffusion-weighted imaging sequences and apparent diffusion coefficient maps. We studied infarct volume thresholds for prediction of catastrophic outcomes, and analyzed sensitivity, specificity, and the area under the curve, a value ≥0.70 indicating an acceptable prediction. RESULTS: Of 173 patients (109 men, 63%; median age 53 years), 42 (24.3%) had catastrophic outcomes. Magnetic resonance imaging b1000 diffusion-weighted imaging and apparent diffusion coefficient infarct volumes were associated to the occurrence of 1-year catastrophic outcome (adjusted odds ratio, 9.17 [95% CI, 2.00-42.04] and odds ratio, 4.18 [95% CI, 1.33-13.19], respectively, per 1 log increase). The optimal volume cutoff of were 211 mL on b1000 diffusion-weighted imaging and 181 mL on apparent diffusion coefficient maps. The 2 methods showed similar sensitivities and specificities and overlapping area under the curve of 0.64 (95% CI, 0.54-0.74). CONCLUSIONS: In patients with large middle cerebral artery infarcts, optimal magnetic resonance imaging infarct volume thresholds showed poor accuracy and low specificity to predict 1-year catastrophic outcome, with different b1000 diffusion-weighted imaging and apparent diffusion coefficient thresholds. In the setting of DH, optimal infarct volumes alone should not be used to deny DH, irrespectively of the method used.

BACKGROUND: We investigated a novel surgical approach to decompressive craniectomy (DC), the bifrontal biparietal, or "cruciate," craniectomy, in severe pediatric traumatic brain injury (TBI). Cruciate DC was designed with a fundamentally different approach to intracranial pressure (ICP) control compared to traditional DC. Cruciate DC involves craniectomies in all 4 skull quadrants. The sagittal and coronal bone struts are disarticulated at the skull to allow the decompression of the sagittal sinus and bridging veins in addition to permitting cerebral expansion, thereby maintaining cranial compliance. OBJECTIVE: To characterize ICP control with cruciate DC in pediatric TBI. METHODS: We performed a retrospective review of TBI patients who underwent cruciate DC. We investigated mortality and preoperative and postoperative ICP. Group 1 underwent medical therapy prior to DC and Group 2 required immediate DC. RESULTS: Fifteen of 18 patients survived. In Group 1, mean preoperative ICP was 18.5 mm Hg and mean postoperative ICP was 11.5 mm Hg. In Group 2, mean preoperative ICP was 27.3 mm Hg and mean postoperative ICP was 15.0 mm Hg. CONCLUSION: Cruciate DC was associated with lowering ICP. We observed acute drops in ICP and long-term ICP control. The floating bone struts of the cruciate DC permits the decompression of the sagittal sinus and bridging veins, with maximal relief of cerebral edema.

AIM OF THE STUDY: Cranioplasty is the surgical repair of skull defects, which commonly is performed after traumatic skull injuries due to tumor removal or decompressive craniectomy. Several studies reported improvement in cognitive functions following cranioplasty in patients with severe brain damage. The reasons why exist such clinical improvement is not completely understood, although the increase in cerebrospinal fluid hydrodynamics with the potential improvement of local and global cerebral hemodynamics, blood flow, and metabolism may play a pivotal role. We investigated whether the cranioplasty improved neurological recovery and the whole array of cognitive functions or just some specific domains. MATERIALS AND METHODS: A total of 30 consecutive brain-injured subjects with craniectomy were enrolled and underwent a structured neuropsychological assessment immediately before the cranioplasty, 1 month after the cranioplasty and 1 year after the surgical procedure. RESULTS: Our results showed that cranioplasty may facilitate the cognitive recovery, independently from the surgical timing. Particularly, we observed an important cognitive recovery in the period immediately after cranioplasty, while the improvement trend settles after a lapse of time, and the recovery starts to slow down. CONCLUSIONS: Cranioplasty seems to significantly improve neuropsychological and motor status in the patients with skull defects, independently from cranioplasty timing and patient's clinical status.

OBJECTIVE: To describe the radiological characteristics, surgical indications, procedures, and intracranial pressure monitoring of a representative cohort of severe traumatic brain injury (sTBI) cases collected over the past 25years, and to analyse the changes that have occurred by dividing the period into 3 equal time periods. METHODS: An observational cohort study was conducted on consecutive adult patients (>14years of age) with severe closed TBI (Glasgow Coma Scale score [GCS]≤8) who were admitted during the first 48hours after injury to the Hospital 12 de Octubre from 1987 to 2012. The most relevant radiological findings, surgical procedures, and intracranial monitoring indications reported in the literature were defined and compared in 3 equal time periods (1987-1995, 1996-2004, and 2005-2014). RESULTS: A significant increase was observed in subdural haematomas with lesions over 25cc, and midline shift in the last period of time. The incidence of subarachnoid haemorrhage increased significantly with time. There was a progression to a worse computed tomography (CT) classification from the initial CT scan in 33% of cases. Surgery was performed on 721 (39.4%) patients. Early surgery (<12hours) was performed on 585 (81.1%) patients, with the most frequent being for extra-cerebral mass lesions (subdural and epidural haematomas), whereas delayed surgery (>12hours) was most frequently performed due to an intracerebral haematoma. Surgical treatment, both early and late was significantly lower with respect to the first time period. Decompressive craniectomy with evacuation of the mass lesion was the preferred procedure in the last time period. Intracranial pressure monitoring (ICP) was carried out on 1049 (57.3%) patients, with a significantly higher frequency in the second period of time. There was adherence to Guidelines in 64.4% of cases. Elevated/uncontrolled ICP was more significant in the first time period. CONCLUSIONS: As a result of the epidemiological changes seen in traumatic brain injury, a different pattern of morphological injury is described, as depicted in the CT, leading to a difference in practice during this period of observation.

BACKGROUND: Contralateral subdural hygroma caused by decompressive craniectomy tends to combine with external cerebral herniation, causing neurological deficits. MATERIAL AND METHODS: Nine patients who underwent one-stage, simultaneous cranioplasty and contralateral subdural-peritoneal shunting were included in this study. Clinical outcome was assessed by Glasgow Outcome Scale as well as Glasgow Coma Scale, muscle power scoring system, and complications. RESULTS: Postoperative computed tomography scans demonstrated completely resolved subdural hygroma and reversed midline shifts, indicating excellent outcome. Among these 9 patients, 4 patients (44%) had improved GOS following the proposed surgery. Four out of 4 patients with lethargy became alert and orientated following surgical intervention. Muscle strength improved significantly 5 months after surgery in 7 out of 7 patients with weakness. Two out of 9 patients presented with drowsiness due to hydrocephalus at an average time of 65 days after surgery. Double gradient shunting is useful to eliminate the respective hydrocephalus and contralateral subdural hygroma. CONCLUSION: The described surgical technique is effective in treating symptomatic contralateral subdural hygroma following decompressive craniectomy and is associated with an excellent structural and functional outcome. However, subdural-peritoneal shunting plus cranioplasty thoroughly resolves the subdural hygroma collection, which might deteriorate the cerebrospinal fluid circulation, leading to hydrocephalus.

OBJECTIVE: To define the incidence of new contralateral intracranial lesions following decompressive hemicraniectomy for blunt traumatic brain injury, and explore the potential association with metabolic factors that contribute to coagulopathy. METHODS: We retrospectively reviewed the records and imaging of all patients treated with hemicraniectomy for blunt traumatic brain injury at our institution from May 2007 up to and including January 2012. RESULTS: Twenty patients were identified during the time period to have undergone decompressive craniectomy for blunt head injury. The average age and Glasgow Coma Scale on presentation was 44.1 years (range: 19 72 years) and 6.5 (range: 3 14) respectively. All but one patient presented with an extra-axial hematoma as their surgical indication for craniectomy. Seven patients (35.0%) developed new contralateral lesions post-craniectomy. The average peri-operative pH, bicarbonate (HCO3) and hematocrit (HCT) levels for those with new contralateral lesions were lower than those without new lesions. Five of the seven patients (71.4%) with new lesions had abnormalities on their laboratory results that have been know to be attributable to coagulopathy, with four (57.1%) having two or more abnormal results. Eight of 13 (61.5%) patients without new lesion had laboratory abnormalites, with five (38.5%) having two or more abnormalities identified. CONCLUSIONS: The incidence of new contralateral lesions post-craniectomy for blunt head injury is 35.0% in our experience. There is an association between the metabolic derangements linked to trauma related coagulopathy and the formation of new lesions.

Decompressive craniectomy (DC) for the management of severe traumatic brain injury (TBI) has a long history but remains controversial. Although DC has been shown to improve both survival and functional outcome in patients with malignant cerebral infarctions, evidence of benefit in patients with TBI is decidedly more mixed. Craniectomy can clearly be life-saving in the presence of medically intractable elevations of intracranial pressure. Craniectomy also has been consistently demonstrated to reduce "therapeutic intensity" in the ICU, to reduce the need for intracranial-pressure-directed and brain-oxygen-directed interventions, and to reduce ICU length of stay. Still, the only randomized trial of DC in TBI failed to demonstrate any benefit. Studies of therapies for TBI, including hemicraniectomy, are challenging owing to the inherent heterogeneity in the pathophysiology observed in this disease. Craniectomy can be life-saving for patients with severe TBI, but many questions remain regarding its ideal application, and the outcome remains highly correlated with the severity of the initial injury.

BACKGROUND: Primary decompressive craniectomy (DC) is commonly performed for patients with traumatic brain injury (TBI). Some, but not all patients, will benefit from invasive monitoring of intracranial pressure (ICP) after surgery. We intended to identify risk factors for elevated ICP after primary DC to treat TBI. METHODS: A retrospective chart review study identified all patients at our institution who underwent primary DC for TBI during the study period and who had ICP monitors placed at the time of surgery. Various preoperative and intraoperative variables were assessed for correlation with the presence of postoperative elevated ICP. RESULTS: Postoperative elevated ICP occurred in 36% of patients after DC. In univariate analysis, Glasgow Coma Scale <8, abnormal pupillary examination, and intraoperative brain swelling were all associated with elevated postoperative ICP. However, in multivariate analysis only intraoperative brain swelling was associated with elevated postoperative ICP (incidence 56% vs. 5%, P = 0.0043). CONCLUSIONS: Placement of an ICP monitor at the time of primary DC for patients with TBI should be considered if there is intraoperative brain swelling.

Recently, a multicenter randomized controlled trial (RCT) by Cooper and colleagues indicated that decompressive craniectomy (DC) may be associated with a worse functional outcome in patients with diffuse traumatic brain injury (TBI), although DC can immediately and constantly reduce intracranial pressure (ICP). As this trial is well planned and of high quality, the unexpected result is meaningful. However, the evidence of the study is insufficient and the effect of DC in severe TBI is still uncertain. Additional multicenter RCTs are necessary to provide class I evidence on the role of DC in the treatment of refractory raised ICP after severe TBI.

OBJECTIVE: Decompressive craniectomy (DC) is a standard neurosurgical procedure against intractable intracranial hypertension. Patients with severe aneurysmal subarachnoid hemorrhage (aSAH) are prone to intracranial hypertension, necessitating DC in certain cases. However, the clinical utility of DC after aSAH remains unclear. Hereby we present a systematic review and meta-analysis summarizing the published studies on DC in aSAH patients. MATERIAL AND METHODS: We systematically searched PubMed, Scopus, Web of Science and Cochrane Library for articles published before Jul 10, 2019 reporting on rates, outcome, indications, timing and complications of SAH patients undergoing DC. RESULTS: Of 1085 identified unique records, 28 observational studies published between 1993 and 2018 were included. In total, data of 2788 aSAH patients was extracted including 2014 patients with DC. The mean DC rate was 10.9 % (range 3.3%-25.6%). Good initial clinical condition (p = 0.01; odds ratio (OR) = 2.93; confidence interval (95 % CI) 1.30-6.61) and younger patients' age (p = 0.02; mean difference (MD) = -4.50; 95 % CI -8.36 - -0.64) increased the chance of good outcome after DC. Overall, patients with primary DC showed a tendency towards better outcome than those that underwent secondary DC (p = 0.08; OR = 1.50; 95 % CI 0.96-2.35). Younger age (p < 0.00001; MD = -3.63; 95 % CI -5.20 to -2.06), presence of intracerebral hemorrhage (ICH; p < 0.00001; OR = 6.63; 95 % CI 3.98-11.03), poor initial clinical condition (p < 0.00001; OR = 4.81; 95 % CI 2.88-8.03) and treatment modality (coiling, p < 0.00001; OR = 0.19; 95 % CI 0.10-0.35) were associated with the indication to DC. CONCLUSIONS: Around 10 % of aSAH individuals undergo DC. Younger individuals, with poor initial clinical condition, additional ICH and aneurysm clipping are more likely to be selected for DC. Due to expected outcome benefit, younger individuals with good-grade aSAH should be considered for early decompression in case of increased intracranial pressure.

OBJECTIVE: Primary decompressive craniectomy (DC) is an important therapeutic technique for severe head-injured patients with space-occupying lesions in emergency situations, but these patients are still at high risk for unfavorable outcomes. This study aimed to investigate the predictors of 30-day mortality in adult patients undergoing primary DC after traumatic brain injury (TBI). METHODS: All adult patients (≥18 years of age) who underwent primary DC from January 2012 to March 2019 were included. Demographic, clinical, surgical, and laboratory variables were collected for analysis. Early mortality was defined as 30-day mortality after DC. First, a univariate analysis (P < 0.05) was used to compare survivors and nonsurvivors. Multivariate logistic regression analysis was used to identify the predictors of 30-day mortality for patients who underwent primary DC. RESULTS: A total of 387 patients were enrolled in the study. The 30-day mortality was 31.52% (122/387). The median age at presentation was 49 years (interquartile range, 38-60), and 316 (81.65%) patients were male. In the multivariate logistic regression analysis, the factors associated with 30-day mortality included age (odds ratio [OR], 1.068; 95% confidence interval [CI], 1.040-1.096; P < 0.001), bilateral unreactive pupils (OR, 12.734; 95% CI, 4.129-39.270; P < 0.001), subdural hemorrhage (OR, 3.468; 95% CI, 1.305-9.218; P < 0.013), completely effaced basal cistern (OR, 3.52; 95% CI, 1.568-7.901; P = 0.002), intraoperative hypotension (OR, 11.532; 95% CI, 4.222-31.499; P < 0.001), preoperative activated partial thromboplastin time (OR, 6.905; 95% CI, 2.055-23.202; P = 0.002), and Injury Severity Score (OR, 1.081; 95% CI, 1.031-1.133; P = 0.002). CONCLUSIONS: In patients undergoing primary DC after traumatic brain injury, the predictors of 30-day mortality include age, bilateral unreactive pupils, subdural hemorrhage, completely effaced basal cistern, intraoperative hypotension, preoperative activated partial thromboplastin time, and Injury Severity Score.

AIM: To observe the effect of early hyperbaric oxygen (HBO) therapy on the improvement of consciousness and prognosis of patients with severe brain damages after craniocerebral craniotomy. MATERIAL AND METHODS: Eighty-one patients who had cerebral hemorrhage and underwent clearance of hematoma and decompressive craniectomy from August 2013 to August 2016 were retrospectively analyzed. The patients were divided into HBO and non-HBO therapy groups. The treatment effects were scored and subjected to corresponding statistical analysis. RESULTS: There were significant differences in the Glasgow coma scale (GCS) scores at 3 and 5 weeks (t=2.293 and t=3.014, respectively, p < 0.05), and in Glasgow outcome scale (GOS) scores at 5 weeks and 3 months between the two groups (p < 0.05). CONCLUSION: Early HBO therapy could improve the consciousness and prognosis of patients with cerebral hemorrhage after craniotomy.

OBJECTIVE: In the present study, we updated our previously reported case series of patients who had undergone decompressive craniectomy for malignant middle cerebral artery infarction (mMCAI) (2005-2020). To the best of our knowledge, the present case series constitutes the largest reported series from a UK neurosurgical unit of decompressive craniectomy for mMCAI. METHODS: We extracted data regarding the clinical discriminators, surgical timescales, and functional outcomes of patients. RESULTS: A total of 67 patients had undergone decompressive craniectomy. The 30-day mortality was 17.9% (n = 12). Of the 67 patients, 31 were male (46.3%) and 36 were female (53.7%). Their mean age was 45 years (range, 16-64 years). The mean age of the survivors was 43 years (range, 16-62 years) compared with 50 years (range, 38-64 years) for those who had died. The median ictal and preoperative Glasgow coma scale score was 14 (range, 7-15) and 8 (range, 3-15), respectively. The corresponding motor scores were 6 and 5. The mean interval from ictus to neurosurgical unit admission was 18.25 hours (range, 0.5-66 hours) and from admission to decompressive craniotomy was 7.30 hours (range, 0.5-46 hours). Of the 67 patients, 63% had undergone "early" craniectomy (<48 hours from mMCAI evolution), with 89% of these patients having undergone craniectomy <24 hours after neurosurgical unit admission. The mean maximum anteroposterior craniectomy diameter was 13.01 cm (range, 10.29-15.56 cm), and mean surface area was 94.38 cm2 (range, 74.75-132.32 cm2). Overall, 46% of patients had had a modified Rankin scale score of <3 (range, 0-6) from discharge to 12 months postoperatively. The median neurosurgical unit length of stay was 15 days (range, 6 hours to 365 days). CONCLUSIONS: The findings from the present update have confirmed that local practice has remained consistent with current evidence. However, patient selection might be optimized if diffusion-weighted magnetic resonance imaging and computed tomography perfusion were used at the original middle cerebral artery infarct admission.

BACKGROUND: Decompressive hemicraniectomy (DH) is widely recommended as a surgical treatment for intractable increased intracranial pressure after malignant cerebral infarction. Many patients given recombinant tissue plasminogen activator (rtPA) develop cerebral edema after reperfusion or failed recanalization. However, the safety and efficacy of DH after rtPA administration remain largely unknown. METHODS: A systematic review was performed using PubMed, Embase, Scopus, Cochrane, and HERDIN. Studies were eligible if they included patients who underwent DH after intravenous thrombolysis for acute ischemic stroke. Unweighted odds ratio (OR) for mortality (primary outcome) and good functional outcome defined as modified Rankin Scale score 0-3 or Glasgow Outcome Scale score 4-5 at 3-6 months (secondary outcome) were compared between the DH + rtPA group and DH alone group. RESULTS: Four studies with a total of 98 patients undergoing DH + rtPA were compared with 110 patients undergoing DH alone without previous thrombolysis. Age, vascular risk factors, and cause of stroke were comparable between the 2 groups. Pooled analysis showed that mortality and functional outcomes were not statistically different between the DH + rtPA and DH alone groups (OR, 0.56, P = 0.07 and OR, 0.83, P = 0.30, respectively). Likewise, both minor and major hemorrhagic rates were similar between the 2 groups (37.76% vs. 27.27%; P = 0.053). CONCLUSIONS: DH for malignant cerebral infarction after intravenous rtPA administration is a viable treatment option, with a comparable mortality and functional outcome to those who had DH without previous thrombolysis.

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.
