Extradural haematoma. Report of 37 consecutive cases with survival

Clinical and Imaging Characteristics, Care Pathways, and Outcomes of Traumatic Epidural Hematomas: A Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury Study

BACKGROUND AND OBJECTIVES

Guideline recommendations for surgical management of traumatic epidural hematomas (EDHs) do not directly address EDHs that co-occur with other intracranial hematomas; the relative rates of isolated vs nonisolated EDHs and guideline adherence are unknown. We describe characteristics of a contemporary cohort of patients with EDHs and identify factors influencing acute surgery.

METHODS

This research was conducted within the longitudinal, observational Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury cohort study which prospectively enrolled patients with traumatic brain injury from 65 hospitals in 18 European countries from 2014 to 2017. All patients with EDH on the first scan were included. We describe clinical, imaging, management, and outcome characteristics and assess associations between site and baseline characteristics and acute EDH surgery, using regression modeling.

RESULTS

In 461 patients with EDH, median age was 41 years (IQR 24-56), 76% were male, and median EDH volume was 5 cm3 (IQR 2-20). Concomitant acute subdural hematomas (ASDHs) and/or intraparenchymal hemorrhages were present in 328/461 patients (71%). Acute surgery was performed in 99/461 patients (21%), including 70/86 with EDH volume ≥30 cm3 (81%). Larger EDH volumes (odds ratio [OR] 1.19 [95% CI 1.14-1.24] per cm3 below 30 cm3), smaller ASDH volumes (OR 0.93 [95% CI 0.88-0.97] per cm3), and midline shift (OR 6.63 [95% CI 1.99-22.15]) were associated with acute surgery; between-site variation was observed (median OR 2.08 [95% CI 1.01-3.48]). Six-month Glasgow Outcome Scale-Extended scores ≥5 occurred in 289/389 patients (74%); 41/389 (11%) died.

CONCLUSION

Isolated EDHs are relatively infrequent, and two-thirds of patients harbor concomitant ASDHs and/or intraparenchymal hemorrhages. EDHs ≥30 cm3 are generally evacuated early, adhering to Brain Trauma Foundation guidelines. For heterogeneous intracranial pathology, surgical decision-making is related to clinical status and overall lesion burden. Further research should examine the optimal surgical management of EDH with concomitant lesions in traumatic brain injury, to inform updated guidelines.

Surgical management of traumatic extradural haematoma: Experiences with 610 patients and prospective analysis

This study was carried out to find out the age, sex, mode of injury, localization, clinical presentation, CT findings, operative measures and outcome of extradural haematoma in the patient population at Dhaka Medical College. 610 consecutive patients with cranial extradural haematoma who underwent surgery in department of Neurosurgery from 1st January 2006 to 6th October 2008 were included in this prospective study. Each of the patients were evaluated in term of age, sex, mode of injury, localization of haematoma, clinical presentation, CT findings, operative measures and outcome. Out of 610 cases 86.32 % were male and 13.78 % were female. The male and female ratio was 6.27: 1. Age ranged from 2.5 to 83 years. Commonest age group was 21 to 30 years. Commonest mode of injury was Road traffic Accident 53.45%, followed by Assaults. Most common clinical presentation was headache / Vomiting 63.61 %, followed by altered sensorium 60.66 %. In this present prospective study of 610 cases of EDH, temporo parietal site was involved in 33.45 % followed by frontal region in 23.28 %. Sixty five patients (10.66 %) died; 19 of these had associated brain injuries and 28 cases were deeply unconscious. Extradural haematoma is a neurosurgical emergency where early surgical intervention is associated with the best prognosis. Many factors affects the outcome of extradural haematoma surgery and the most important one is the duration of time between incident/accident and operation in neurosurgical operation theater; mortality can be close to 0% if this time interval can be minimized.

[Guidelines for the management of severe traumatic brain injury. Part 3. Surgical management of severe traumatic brain injury (Options)]

Traumatic brain injury (TBI) is one of the main causes of mortality and severe disability in young and middle age patients. Patients with severe TBI, who are in coma, are of particular concern. Adequate diagnosis of primary brain injuries and timely prevention and treatment of secondary injury mechanisms markedly affect the possibility of reducing mortality and severe disability. The present guidelines are based on the authors' experience in developing international and national recommendations for the diagnosis and treatment of mild TBI, penetrating gunshot wounds of the skull and brain, severe TBI, and severe consequences of brain injury, including a vegetative state. In addition, we used the materials of international and national guidelines for the diagnosis, intensive care, and surgical treatment of severe TBI, which were published in recent years. The proposed recommendations for surgical treatment of severe TBI in adults are addressed primarily to neurosurgeons, neurologists, neuroradiologists, anesthesiologists, and intensivists who are routinely involved in treating these patients.

Craniotomy Versus Craniectomy for Acute Traumatic Subdural Hematoma in the United States: A National Retrospective Cohort Analysis

OBJECTIVE

The optimal surgical management of acute traumatic subdural hematoma (ASDH) is controversial; both craniectomy and craniotomy are performed. The purpose of this study was to determine the current management of ASDH in the United States.

METHODS

This retrospective cohort study used the Nationwide Inpatient Sample from the years 2006-2011 to examine patients with a primary diagnosis of ASDH. All patients ≥18 years old with a primary diagnosis of ASDH were included in the analysis. Patients with procedure codes for craniectomy and craniotomy were isolated from the database. Propensity score matching based on logistic regression was used to match craniotomy to craniectomy in a 1:1 fashion.

RESULTS

There were 47,911,414 hospitalizations analyzed. Of 60,435 patients with ASDH identified, 1763 underwent craniotomy and 177 underwent craniectomy. The average age of patients who underwent craniectomy was 49.5 years (SD 20.8) compared with an average age of 68.9 years (SD 17.1) of patients who underwent craniotomy (P < 0.0001). Hospital mortality was significantly higher in patients who underwent craniectomy (35.0% vs. 10.9%, P < 0.0001). Patients who underwent craniectomy had longer hospital stays compared with patients who underwent craniotomy (median duration 14.3 days [interquartile range 25] for craniectomy vs. 10.9 days [interquartile range 9] for craniotomy, P < 0.0001). Patients who underwent craniectomy were also more likely to be discharged to a skilled nursing or rehabilitation facility (79.1% vs. 63.9%, P = 0.0011).

CONCLUSIONS

Craniotomy is the preferred surgical technique for management of ASDH in the United States, being performed 10 times more frequently than craniectomy. Craniectomy was associated with significantly higher in-hospital mortality after propensity score matched analysis.

Local skull trephination before transfer is associated with favorable outcomes in cerebral herniation from epidural hematoma

OBJECTIVES

The patient with epidural hematoma and cerebral herniation has a good prognosis with immediate drainage, but a poor prognosis with delay to decompression. Such patients who present to nonneurosurgical hospitals are commonly transferred without drainage to the nearest neurosurgical center. This practice has never been demonstrated to be the safest approach to treating these patients. A significant minority of emergency physicians (EPs) have advised and taught bedside burr hole drainage or skull trephination before transfer for herniating patients. The objective of this study was to assess the effect of nonneurosurgeon drainage on neurologic outcome in patients with cerebral herniation from epidural hematoma.

METHODS

A structured literature review was performed using EMBASE, the Cochrane Library, and the Emergency Medicine Abstracts database.

RESULTS

No evidence meeting methodologic criteria was found describing outcomes in patients transferred without decompressive procedures. For patients receiving local drainage before transfer, 100% had favorable outcomes.

CONCLUSIONS

Although the total number of patients is small and the population highly selected, the natural history of cerebral herniation from epidural hematoma and the best available evidence suggests that herniating patients have improved outcomes with drainage procedures before transport.

Acute epidural hematoma with infarction of the right hemisphere in a 5-month-old child: case report with a long-term follow-up and a review of the literature

Two hours after a fall, a 5-month-old girl was admitted to our hospital because of an extended galea hematoma and restlessness. Five hours after the trauma, a left hemiparesis developed. The child became drowsy. The hematocrit had fallen to 7.1 g/dL. Cranial computerized tomography disclosed a huge frontoparietal epidural hematoma on the right side and a hypodensity in the territories of the middle and posterior cerebral arteries. Immediately before surgery, the right pupil dilated. After evacuation of the epidural hematoma and ligation of the middle meningeal artery, the girl recovered satisfactorily. Nevertheless, magnetic resonance imaging showed a vast defect zone in the territories of the right middle and posterior cerebral arteries. Six weeks after the injury, the visual-evoked potentials were unavailable on both sides. Four years after the accident, visual assessment revealed normal acuity and stereopsis. Cognitive and neuromotor development were undisturbed and appropriate to the age.

Outcome of traumatic extradural haematoma in Hong Kong

AIM

Traumatic extradural haematoma (EDH) is a neurosurgical emergency and timely surgical intervention for significant EDH is the gold standard. This study aims to determine the incidence and mortality of consecutive patients with traumatic EDH admitted to the Emergency Department (ED) of Prince of Wales Hospital (PWH), a University Hospital Trauma Centre in Hong Kong.

PATIENTS AND METHODS

Retrospective analysis of prospectively collected data for all consecutive trauma cases admitted through the ED during 2001-2004. EDH was diagnosed by CT in all cases. Both primary and delayed onset EDH were included, as were patients with combined EDH and other intracranial lesions (e.g. subdural haematoma). Age, sex, cause of injury, associated intracranial lesions, skull fracture, Glasgow Coma Scale, pupil reactivity, treatment, length of stay and clinical outcome were determined.

RESULTS

Two thousand and two hundred and eight patients were in the trauma registry for 2001-2004. Total 1080 head injured patients; 89 patients had traumatic EDH, mean of 1.9 patients per month. Seventy (79%) patients were male, with a mean age of 37.7 years. Fifty (56%) patients were from road traffic crashes, 27 (30%) sustained falls, 10 (11%) had direct head trauma. On admission, 62 (70%) patients were GCS 13-15, 9 (10%) GCS 9-12 and 18 (20%) GCS 3-8. Sixty-six (74%) patients had a skull fracture. Thirty (34%) patients underwent neurosurgical operation. Overall, nine patients (10%) died; eight patients were GCS<8; five had bilateral fixed and dilated pupils; one had a single fixed and dilated pupil. Four patients died after neurosurgical operation, three of whom had fixed dilated pupils and were GCS 3 prior to surgery. Median length of hospital stay for survivors was 10.4 days.

CONCLUSION

Survival from traumatic EDH was 90% (80/89) and 91% (73/80) of survivors had a Glasgow Outcome Score of 4 or 5 (good or moderate). The combination of bilateral fixed dilated pupils and GCS 3 suggests severe primary brain injury. Emergency evacuation of intracranial haematomas is unlikely to improve the outcome for these patients. Even in an urban environment with short prehospital times and rapid access to neurosurgery, outcome in patients who are GCS 3 following EDH is likely to be poor.

EFNS guideline on mild traumatic brain injury: report of an EFNS task force

In 1999, a Task Force on Mild Traumatic Brain Injury (MTBI) was set up under the auspices of the European Federation of Neurological Societies. Its aim was to propose an acceptable uniform nomenclature for MTBI and definition of MTBI, and to develop a set of rules to guide initial management with respect to ancillary investigations, hospital admission, observation and follow-up.

Current controversies in the management of minor pediatric head injuries

Each year hundreds of thousands of children receive care in emergency departments after head injury. Minor head injuries account for a majority of these injuries. The prevalence, morbidity, and costs associated with pediatric minor head injuries make it an important topic. We review the management of pediatric minor head injury, emphasizing current areas of controversy, including criteria for neuroimaging, indications for hospitalization, the role of anticonvulsant therapy, and the long-term neurobehavioral sequelae of pediatric minor head injury.

Factors influencing the functional outcome of patients with acute epidural hematomas: analysis of 200 patients undergoing surgery

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%.

Delayed extradural hematoma after mild head injury: report of three cases

BACKGROUND

Extradural hematoma has been classically considered to be an acute complication of head injury whose maximum development takes place in the minutes following trauma. Delayed extradural hematoma (DEH) is defined on the basis of an exclusively radiologic criterion: epidural hematoma that is not present in the first neuroradiologic examination made after trauma but that appears in sequential neuroradiologic examinations during patient evolution. This is an infrequent complication that usually appears in hypotensive multiple trauma patients or is related to severe head injury with other intracranial lesions.

CASE DESCRIPTION

We present three cases of DEH after mild head injury (GCS > 12) without associated intracranial or traumatic systemic lesions. Therefore, those usually considered to be "protective mechanisms" responsible for delayed development of an extradural hematoma were absent in our three patients. Diagnosis was attained by means of repetition of cranial computed tomography (CT) scan after neurologic impairment was noted. Surgical evacuation of DEH was immediately performed after diagnosis. Postoperative outcome was favorable in two patients who suffered DEH in the supratentorial compartment. One patient who presented a posterior fossa DEH died 3 days after surgery.

CONCLUSIONS

Early diagnosis and immediate treatment have proved to be essential for improving the prognosis of patients affected by DEH. Hospital admission under neurologic observation is recommended for patients who have sustained mild head injury associated with those factors that are related to the development of DEH, including GCS score under 15 or the detection of a skull fracture. Normality of a CT scan does not rule out subsequent appearance of delayed traumatic lesions.

Prognostic factors in severely head injured adult patients with epidural haematoma's

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.
