Abstract
BACKGROUND Epidural hematoma (EDH) can result in a catastrophic outcome of traumatic brain injury. Current management guidelines do not consider the source of hemorrhage in decision making. The purpose of this study was to examine the relationship between EDH location and the source of hemorrhage. METHODS We report retrospectively reviewed, prospectively obtained surgical data of patients with acute traumatic cranial EDH treated between 2007 and 2018. Computed tomography (CT) scans were used to categorize EDH location as lateral or medial. The source of hemorrhage was identified intraoperatively by a single surgeon. RESULTS Overall, of 92 evacuated EDHs (in 87 patients), 71 (77.2%) were in the lateral location. Arterial bleeding was the cause of EDH in 63.4% of the lateral EDHs and 9.2% of the medial EDHs (P < 0.0001). In the cases where surgery was done primarily to treat EDH, 65.3% had an arterial bleed source (P < 0.0001). In those treated for primary reasons other than EDH evacuation, 75% had a venous bleed source (P = 0.002). CONCLUSIONS The location of EDH correlates with the source of hemorrhage. The decision to operate on EDH may be influenced by this factor.

Abstract
Background. The natural history of traumatic aneurysms of the middle meningeal artery (MMA) is not well known, but patients with these lesions are more likely to have delayed bleeds. In this paper, we described a series of patients with epidural hematoma who underwent angiotomography (CTA) for MMA vascular lesion diagnosis. Methods. Eleven patients admitted to our emergency unit with small acute epidural hematoma were prospectively studied. All patients with temporal acute epidural hematomas underwent CTA and cerebral angiogram at our institution for diagnosis of posttraumatic lesions of middle meningeal artery. The findings of angiotomography and digital angiography were reviewed by radiologist and angiographers, respectively, to ensure that the lesions were readily diagnosed without knowing the results of angiotomography and to compare CTA findings with standard angiogram. Results. The causes of head injury were traffic accidents, falls, and aggression. Three of these patients presented traumatic MMA pseudoaneurysm. CT angiography was able to diagnose all of them, with dimensions ranging from 1.5 to 2.8 mm. Conventional angiography confirmed the findings of CT angiography, and the lesions presented with similar dimensions at both methods. Conclusions. We believe that angiotomography can be a useful technique for diagnosis of vascular lesion associated with small epidural hematoma.

Abstract
Traumatic Brain Injury (TBI) is among the most frequent neurological disorders. Of all TBIs 90% are considered mild with an annual incidence of 100–300/100.000. Intracranial complications of Mild Traumatic Brain Injury (MTBI) are infrequent (10%), requiring neurosurgical intervention in a minority of cases (1%), but potentially life-threatening (case fatality rate 0,1%). Hence, a true health management problem exists because of the need to exclude the small chance of a life threatening complication in large numbers of individual patients. The 2002 EFNS guidelines used a best evidence approach based on the literature until 2001 to guide initial management with respect to indications for CT, hospital admission, observation and follow up of MTBI patients. This updated EFNS guideline version for initial management inMTBI proposes a more selectively strategy for CT when major (dangerous mechanism, GCS<15, 2 points deterioration on the GCS, clinical signs of (basal) skull fracture, vomiting, anticoagulation therapy, post traumatic seizure) or minor (age, loss of consciousness, persistent anterograde amnesia, focal deficit, skull contusion, deterioration on the GCS) risk factors are present based on published decision rules with a high level of evidence. In addition clinical decision rules for CT now exist for children as well. Since 2001 recommendations, although with a lower level of evidence, have been published for clinical in hospital observation to prevent and treat other potential threads to the patient including behavioral disturbances (amnesia, confusion and agitation) and infection.

Abstract
Abstract
OBJECTIVE
We studied the angiographic findings in patients with small epidural hematomas and cranial fractures crossing over the trajectory of the middle meningeal artery and its branches. Additionally, the occurrence of traumatic vascular lesions and their clinical relevance and treatment are discussed.
METHODS
A consecutive analysis was performed for 24 patients who harbored small epidural hematomas in middle meningeal artery topography associated with cranial fractures. Computed tomographic scans and plain x-ray studies were used to diagnose linear cranial fractures. Patients with large epidural hematomas or associated traumatic lesions were excluded from the study. Selective ipsilateral external carotid angiograms were obtained, and an endovascular procedure was performed if any vascular injury was evidenced.
RESULTS
In all patients with cranial fractures crossing over the middle meningeal artery and its branches, some kind of vascular lesion was seen. Two types of findings were noted: active extravasation of the contrast medium (71%) and pseudoaneurysms (29%). Early filling of diploic vessels was found in 8.3% of fractures concomitantly with active extravasation. Embolization was performed in all patients. No additional enlargement of the epidural hematoma was observed, and the postoperative period was uneventful.
CONCLUSION
This study shows that pseudoaneurysms and active extravasation of contrast are common findings in this subset of patients. Although the natural history of these lesions is still poorly understood, additional investigation with ipsilateral external carotid angiography may be recommended, considering the potentially catastrophic consequences of late rupture.

Abstract
PRIMARY OBJECTIVE To examine and compare a sample of head injury care instruction forms available in hospital emergency departments (EDs) against evidence-based factors predictive of haemorrhage or traumatic lesions and to propose an easy-to-understand discharge instruction form for patients with concussion or mild traumatic brain injury (MTBI). RESEARCH DESIGN/METHODS Fifteen hospital discharge instruction forms were reviewed for inclusion of six factors known to be associated with the presence of haemorrhage after MTBI. ED instruction forms were also evaluated for readability. RESULTS The 15 hospital ED instruction forms varied in what patients' caretakers were instructed to observe. Some but not all important factors associated with haemorrhage were included. The mean Flesch-Kincaid reading grade level of the discharge instruction forms was 8.2 with a mean Reading Ease score of 59.9%. CONCLUSION EDs use discharge instruction forms listing signs and symptoms that are highly variable, confusing, not all evidence-based and often not easy to understand. This review proposes a discharge instruction form containing the six best evidence-based variables (according to the current literature) as being useful and understandable to patients and their families for home observation after MTBI.

Abstract
SUMMARY A young patient with a facial trauma after a road accident was admitted to our department with incoercible epistaxis. A CT scan showed a right pterional acute epidural hematoma (EDH). Angiography demonstrated multiple sources of bleeding of the right sphenopalatine arteries, cause of the epistaxis, and an intracranial leakage of the right middle meningeal artery, responsible for the EDH. The patient immediately underwent embolization of the right internal maxillary artery and right middle meningeal artery. The procedure stopped the epistaxis and no further enlargement of the EDH was observed, avoiding its surgical treatment. Endovascular surgery may be an effective procedure to stop the arterial meningeal bleeding sustaining acute EDH and may be a useful tool in the management of special cases of post traumatic EDH.

Abstract
BACKGROUND There is considerable uncertainty about the indications for cranial computed tomography (CT) scanning in patient with minor traumatic brain injury (TBI). This analysis involves an evidence-based comparison of several strategies for selecting patients for CT with regard to effectiveness and cost. METHODS We performed a structured literature review of mild traumatic brain injury and constructed a cost-effectiveness model. The model estimated the impact of missed intracranial lesions on longevity, quality of life and costs. Using a 20-year-old patient for primary analysis, we compared the following strategies to screen for the need to perform a CT scan: observation in the emergency department or hospital floor, skull radiography, Selective CT based on the presence of additional risk factors and scanning all. RESULTS Outcome measures for each strategy included average years of life, quality of life and costs. Selective CT and the CT All policy performed significantly better than the alternatives with respect to outcome. They were also less expensive in terms of total direct health care costs, although the differences did not reach statistical significance. The model yielded similar, but smaller, differences between the selective imaging and other strategies when run for older patients. CONCLUSIONS Although the incidence of intracranial lesions, especially those that require surgery, is low in mild TBI, the consequences of delayed diagnosis are forbidding. Adverse outcome of an intracranial hematoma is so costly that it more than balances the expense of CT scans. In our cost-effectiveness model, the liberal use of CT scanning in mild TBI appears justified.

Abstract
OBJECTIVE To search the literature for case reports on adverse outcomes in patients with mild head injury where acute computed tomography (CT) findings had been normal. METHODS Mild head injury was defined as head trauma involving amnesia or loss of consciousness, but where neurological findings are normal on arrival at hospital (GCS 15). The scientific literature was systematically searched for case reports where an early CT was normal and the patient deteriorated within two days. In these cases, early discharge despite a normal CT head scan would have been hazardous. RESULTS Two prospective studies were found that investigated the safety of early CT in 3300 patients with mild head injury, as were 39 reports on adverse outcomes describing 821 patients. In addition, 52 studies containing over 62 000 patients with mild head injury were reviewed. In total, only three cases were deemed to have experienced an early adverse outcome despite a normal CT and GCS 15 on initial presentation. In another eight cases with incomplete descriptions, the interpretation was doubtful. Many reports of complications were not relevant to our question and excluded. These reports included cases with more severe head injury/not GCS 15 at presentation, complications that occurred after more than two days, or initial CT findings that were not fully normal. CONCLUSION Very few cases were found where an early adverse event occurred after normal acute CT in patients with mild head injury. The strongest scientific evidence available at this time shows that a CT strategy is a safe way to triage patients for admission.

Abstract
BACKGROUND Previous studies have presented conflicting results regarding the predictive effect of various clinical symptoms, signs, and plain imaging for intracranial pathology in children with minor head injury. AIMS To perform a meta-analysis of the literature in order to assess the significance of these factors and intracranial haemorrhage (ICH) in the paediatric population. METHODS The literature was searched using Medline, Embase, Experts, and the grey literature. Reference lists of major guidelines were crosschecked. Control or nested case-control studies of children with head injury who had skull radiography, recording of common symptoms and signs, and head computed tomography (CT) were selected. OUTCOME VARIABLE CT presence or absence of ICH. RESULTS Sixteen papers were identified as satisfying criteria for inclusion in the meta-analysis, although not every paper contained data on every correlate. Available evidence gave pooled patient numbers from 1136 to 22 420. Skull fracture gave a relative risk ratio of 6.13 (95% CI 3.35 to 11.2), headache 1.02 (95% CI 0.62 to 1.69), vomiting 0.88 (95% CI 0.67 to 1.15), focal neurology 9.43 (2.89 to 30.8), seizures 2.82 (95% CI 0.89 to 9.00), LOC 2.23 (95% CI 1.20 to 4.16), and Glasgow Coma Scale (GCS) <15 of 5.51 (95% CI 1.59 to 19.0). CONCLUSIONS There was a statistically significant correlation between intracranial haemorrhage and skull fracture, focal neurology, loss of consciousness, and GCS abnormality. Headache and vomiting were not found to be predictive and there was great variability in the predictive ability of seizures. More information is required about the current predictor variables so that more refined guidelines can be developed. Further research is currently underway by three large study groups.

Abstract
The lack of a common, widely acceptable criterion for the definition of trivial, minor, or mild head injury has led to confusion and difficulty in comparing findings in published series. This review proposes that acute head-injured patients previously described as minor, mild, or trivial are defined as "mild head injury," and that further groups are recognized and classified as "low-risk mild head injury," "medium risk mild head injury," or "high-risk mild head injury." Low-risk mild injury patients are those with a Glasgow Coma Score (GCS) of 15 and without a history of loss of consciousness, amnesia, vomiting, or diffuse headache. The risk of intracranial hematoma requiring surgical evacuation is definitively less than 0.1:100. These patients can be sent home with written recommendations. Medium risk mild injury patients have a GCS of 15 and one or more of the following symptoms: loss of consciousness, amnesia, vomiting, or diffuse headache. The risk of intracranial hematoma requiring surgical evacuation is in the range of 1-3:100. Where there is one computed tomography (CT) scanner available in an area for 100,000 people or less, a CT scan should be obtained for such patients. If CT scanning is not so readily available, adults should have a skull x-ray and, if this shows a fracture, should be moved to the "high-risk" category and undergo CT scanning. High-risk mild head injury patients are those with an admission GCS of 14 or 15, with a skull fracture and/or neurological deficits. The risk of intracranial hematoma requiring surgical evacuation is in the range 6-10:100. If a CT scan is available for 500,000 people or less, this examination must be obtained. Patients with one of the following risk factors--coagulopathy, drug or alcohol consumption, previous neurosurgical procedures, pretrauma epilepsy, or age over 60 years--are included in the high-risk group independent of the clinical presentation.

Abstract
Computed tomography (CT) has revolutionized the diagnosis and management of head-injured patients, and its increasing availability has led to its liberal use. CT scanning provides excellent anatomic detail of the brain as fixed static images, but the dynamic nature of human physiology means that many injury patterns will evolve in time. We describe an 8-year-old child who had fallen 8 feet from a tree. He had a brief loss of consciousness but a normal neurologic evaluation on arrival to the emergency department (ED). He underwent expedited cranial CT scanning, which revealed no acute brain injury. Two and one half hours later, the patient had a mild depression in consciousness, prompting a second CT scan in the ED, which revealed an acute epidural hematoma. He had acute surgical evacuation of the hematoma and made a full neurologic recovery. This case illustrates that a single early CT examination may at times provide a false sense of security and underscores the importance of serial neurologic examinations.

Abstract
BACKGROUND The Scandinavian Neurotrauma Committee was initiated by the Scandinavian Neurosurgical Society to develop evidence-based guidelines for improved care of neurotrauma patients. METHODS A MEDLINE search identified 475 papers dealing with the management of minimal, mild, and moderate head injuries. Forty-two studies presenting class II evidence on the initial management of such injuries were reviewed and management guidelines were developed. RESULTS Implementation of the Head Injury Severity Scale is advocated. Patients with minimal injuries (no loss of consciousness, Glasgow Coma Scale score of 15) can be safely discharged. Routine early computed tomographic scan is recommended in cases with mild injuries (history of loss of consciousness, Glasgow Coma Scale score = 14-15) and patients with normal scans may be discharged. Computed tomographic scan and admission is mandatory in moderate injuries (Glasgow Coma Scale score = 13). All patients harboring additional risk factors should be scanned and admitted. A flow-chart for clinical decision making and a Head Injury Instruction card is introduced. CONCLUSIONS The Scandinavian Neurotrauma Committee suggests guidelines that should be safe and cost-effective for the initial management of minimal, mild, and moderate head injuries.

Abstract
OBJECTIVE To determine the prognostic factors of the functional outcome of patients surgically treated for acute epidural hematomas. METHODS Two hundred patients who consecutively underwent neurosurgery for acute epidural hematomas over the past 9-year period were studied. Clinical characteristics, radiologic findings, and the time intervals with regard to treatment course were investigated to determine the interactions between all these factors and functional outcome. RESULTS Functional outcome showed a significant correlation with preoperative consciousness state, Glasgow Coma Scale score, pupillary sizes, and motor posturing (chi2 test, p < 0.05). Functional outcome correlated with the period of brain herniation, the length of time of the operation, as well as the period of hospitalization (chi2 test, p < 0.05), but not with the length of time of craniotomy decompression relative to the length of time from the injury until admission. The radiologic findings of the associated brain injury, the size and the density of the clot, the degree of the brain shift, and the obliteration of the basal cisterns significantly correlated with functional outcome (chi2 test, p < 0.05), whereas no significance was attributable to skull fracture. Multivariate analysis indicated that the following four factors independently correlated with functional outcome: (1) associated brain injury, (2) best motor response, (3) hematoma volume, and (4) period of hospitalization (chi2 test, p < 0.05). A combination of the four factors led to the prediction of the functional outcome with 91% accuracy (1.5 % falsely pessimistic predictions and 7.5 % falsely optimistic prediction) and 82.1% at over 90% confidence level. These four parameters correlated significantly with preoperative neurologic deterioration (chi2 test, p < 0.05). CONCLUSION This study identifies the risk factors involved in the functional outcome of patients who underwent surgical treatment for acute epidural hematomas. Our results indicate that associated brain injury plus best motor response are the optimal set of two prognostic indicants, with 87% correct predictions and 70.1% at over a 90% confidence level. Prevention of in-hospital neurologic deterioration would improve the patients' functional outcome with a resultant unfavorable recovery rate ranging from 11.5% to 17%.

Abstract
Ventriculoperitoneal shunt operations represent the most used choice for treating hydrocephalus, although some related complications have been reported. Due to its rarity, potential dangers, and mortality rate, we present two cases of epidural hematoma following ventriculoperitoneal shunt, discussing its pathophysiology and prophylaxis.

Abstract
A medline search back to 1975 was undertaken to identify relevant papers published on epidural haematomas. The search was restricted, whenever possible, to adult age and to comatose patients. Forty four relevant reports were identified. Only 4 papers reported results on multivariate analysis. In terms of prognosis, the following parameters were found to be significant: age, time from injury to treatment, immediate coma or lucid interval, presence of pupillary abnormalities, GCS/motor score on admission. CT findings (haematoma volume, degree of midline shift, presence of signs of active haematoma bleeding, associated intradural lesion) and post-operative ICP. To compare different casistics we need more informations about patients's outcome in the referral area of the neurosurgical centers, about the number of direct admissions and about the number of patients showing clinical deterioration.
