Clinical characteristics of traumatic extradural hematoma: a comparison between children and adults

Axial Convex-Shaped Hematoma was Associated with Poor Curative Effect of Surgical Treatment for Traumatic Posterior Fossa Epidural Hematoma in Children

BACKGROUND

Posterior fossa epidural hematoma (PFEDH) is rare which accounts for just 4-12.9% of all EDH cases. Since its frequently subtle and nonspecific clinical presentation, CT scan has great importance for early diagnosis and treatment of PFEDH. However, indications for surgery depending on the findings of CT image are still controversial.

METHODS

We retrospectively analyzed 40 pediatric cases of PFEDH. Their baseline characteristic, clinical presentation, imaging findings and outcomes were collected and analyzed. The ellipsoid volume equation X × Y × Z/2 was used to measure the hematoma volume. The Glasgow Outcome Scale (GOS) was used to assess the neurologic functional outcome.

RESULTS

A total of 40 pediatric PFEH patients were included with 8 patients having poor outcome and 32 patients having a relatively good prognosis. GCS score showed a significant difference between good and poor outcome groups (p < 0.001). Y value on CT image was significantly bigger in poor outcome group than good outcome group (p < 0.01). Similar results were got in X/Z value (p < 0.05) and Y/Z value (p < 0.01) which reflected the shape of hematoma. A predictive model with Y + X/Z showed the largest area under the ROC curve with a sensitivity of 75.0% and specificity of 93.7%.

CONCLUSIONS

GCS score at admission was closely related to the prognosis of the pediatric patients with PFEDH. The morphometry of PFEDH has a crucial role in judging the prognosis. Axial convex-shaped hematoma was associated with poor curative effect of surgical treatment.

Location of Traumatic Cranial Epidural Hematoma Correlates with the Source of Hemorrhage: A 12-Year Surgical Review

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.

Management of Traumatic Epidural Hematoma in Infants Younger than One Year: 50 Cases - Single Center Experience

AIM AND BACKGROUND

Traumatic epidural hematoma (EDH) is a rare but possibly fatal complication of head trauma in infants. In this study, infants who were younger than 1 year and followed up and treated for TEDH in our clinic were evaluated. Our series is the largest series consisting only infantile cases in the literature.

MATERIAL AND METHODS

There were 50 patients younger than 1 year followed up and treated in our hospital between January 2011 and December 2019. Their age, gender, hospital admission signs and symptoms, trauma type, localization and thickness of the hematoma, and accompanying skull fracture were noted from their hospital files. Decisions for conservative or surgical treatment were made according to neurological status, Children Coma Scale (CCS) score, and EDH thickness, degree of the midline shift on cranial computerized tomography (CT), and presence of additional intracranial pathology.

RESULTS

Patients' age ranged from 0 day to 12 months (7 months as median), and their male/female ratio was 30/20. Falling from a height (<1 m) was the most frequent trauma mechanism, with a 96% rate. The most common finding was irritability and unusual crying (88%). The CCS score was 5-15 (median 13). The hematoma was located most frequently in the parietal region (48%) and least frequently in the posterior fossa (2%). Linear fracture was observed in 62% of the cases. Thirty-nine (78%) patients were treated conservatively (hematoma thickness ≤17 mm). Eleven (22%) cases were surgically treated (hematoma thickness was between 15 and 40 mm (26.3 ± 6.6 mm, mean ± standard deviation [SD]). The midline shift in the operated cases was between 1.8 and 11.8 mm (6.4 ± 3 mm, mean ± SD). One of them with a hematoma thickness of 15 mm was operated for associated open depression fracture above the hematoma. Other 10 patients were operated for primarily hematoma evacuation. None of the patients treated conservatively worsened neurologically or required operation during or after hospitalization. Two patients died (4%) during hospitalization, and both of them were anisocoric on admission. The hospital stay was between 1 and 10 (median 3) days, and the follow-up period of the living patients was between 1 month and 6 years (median 24 months). All of the living patients were neurologically normal on their last controls.

CONCLUSIONS

Because the symptoms and signs in infants are nonspecific, it is difficult to diagnose EDH clinically. Cranial CT should be performed in cases with irritability, swelling of the scalp, pallor, deterioration of consciousness, and anisocoria after head trauma. Traumatic EDHs with normal neurological examination, high CCS score, hematoma thickness below 20 mm, no apparent shift, and without associated brain pathology can be treated conservatively. None of those patients treated conservatively required operation after that.

Compression of the posterior fossa venous sinuses by epidural hemorrhage simulating venous sinus thrombosis: CT and MR findings

BACKGROUND

Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus.

OBJECTIVE

To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall.

MATERIALS AND METHODS

We describe radiologic findings in four children in whom a posterior fossa epidural hemorrhage mimicked dural venous sinus thrombus. Routine CT head and CT venography were obtained on Toshiba volume and helical CT scanners. MRI and MR venography were performed on a Philips scanner.

RESULTS

In all cases there was medial displacement and compression of the posterior fossa dural venous sinuses without intraluminal thrombosis. The epidural hemorrhage was seen tracking along sinus grooves in the occipital bone, peeling the dura containing the sinuses from the calvarium and compressing the sinus, simulating thrombosis on axial CT views.

CONCLUSION

Both venous sinus thrombosis and posterior fossa epidural hemorrhages in children are well-described complications of head trauma. Posterior fossa epidural hemorrhage can mimic a sinus thrombus by compressing and displacing the sinuses. It is important to recognize this pitfall because treatment of a suspected thrombus with anticoagulation can worsen epidural hemorrhage.

Supratentorial extradural hematoma in children: An institutional clinical experience of 65 cases

Aim and Objective:

To survey the epidemiology, management, and severity of extradural hematoma (EDH) in children.

Materials and Methods:

All patients of EDH (n = 65) in the age group of 0–16 years admitted to our department during the period of August 13 and July 14 were analyzed retrospectively from the hospital records. In all patients, age, sex, mode of injury, clinical presentation, site of EDH, management, duration of hospitalization, and outcome were evaluated.

Observation and Results:

Of 65 patients, males were 70.76% with a male to female ratio of 2.4:1, most of the victims (47.69%) were in the age group of 11–16 years. Mean duration of hospitalization was 4.32 days. The most common mode of injury was fall from height in 29 cases (44.61%) followed by road traffic accident (RTA) in 23 cases (35.35%). Temporoparietal EDH was the most common computed tomography finding present in 22 (33.84%) patients. 67.69% patients presented to casualty with minor head injury having Glasgow coma scale (GCS) between 14 and 15. Most common presenting feature was vomiting in 52 cases (80%) and next to it was altered sensorium. The mortality rate was 7.69% (n = 5).

Conclusion:

Extradural hematoma is a life-threatening entity encountered in pediatric head injury. Timely intervention and diagnosis decrease mortality to a great degree. Most of the mortality is encountered in patients who presented late at the neurosurgical unit with low GCS.

Surgical management of traumatic extra dural hematoma in children: Experiences and analysis from 24 consecutively treated patients in a developing country

Background:

Children with epidural hematoma (EDH) present differently than adults. The outcome of treatment is also different. We aim to report our experiences with EDH in pediatric age group in terms of mode of injury, presenting features, management, and outcomes. We also aim to identify different prognostic indicators in pediatric patients with EDH.

Methods:

We prospectively collected data from 24 consecutively surgically treated pediatric patients. The data collected included presenting features, radiological imaging, details of management, and outcomes. Descriptive analysis was performed and different variables were tested for any statistical significance with Glasgow Outcome Score (GOS).

Results:

There were 19 male and 5 female patients. The mean Glasgow Coma Scale (GCS) score at presentation was 9.3 ± 4.4. Falls were the most common cause of EDH. Outcome assessment was done at 3 month follow up. A total of 15 patients had a GOS score of 5, 4 patients had a GOS score of 4, 2 patients had a GOS score of 3, while 3 patients had a GOS score of 1. On univariate analysis, admitting GCS score, patient's age, the time from injury to admission and injury to surgery, anisocoric pupils at presentation and effacement of basal cisterns were significantly associated with the outcome of GOS score.

Conclusion:

Falls are the most common mode of injury leading to EDH in children. Lower GCS at presentation, younger age at trauma, increased time since trauma to surgery and admission, anisocoria and effacement of basal cisterns are statistically significant variables in surgically treated pediatric patients of EDH that confer a poorer prognosis. A timely surgical intervention can result in excellent outcomes.

Traumatic extradural hematoma in childhood

OBJECTIVE

This study was undertaken to assess the clinical and radiological characteristics of children with traumatic extradural hematoma (TEDH), and factors affecting the initial neurological status and outcome.

METHODS

Medical records of 269 consecutive children with TEDH from 2005 to 2012 were retrospectively reviewed, factors affecting the initial neurological status and outcomes were explored using univariate and multivariate analysis.

RESULTS

There were 166 boys and 103 girls (average age: 7.0 years). Fall from a height (59 %) was the most common mechanism of head injury. With increasing age, an increase of motor-vehicle accident and assault was noted. Among the children 85.5 % experienced a Glasgow Coma Scale (GCS) of 13-15, 9.7 % with GCS 9-12, and 4.8 % with GCS 3-8. The main clinical manifestations were headache, vomiting and nausea, and conscious disturbance. The main locations were the temporal, temporoparietal, and frontal regions. The 97.4 % saw a favorable outcome, whereas 2.6 % had a poor outcome (overall mortality: 1.1 %).

CONCLUSION

Many factors influenced the prognosis; the most important factors affecting prognosis were the initial neurological condition and secondary brain edema, while the initial neurological status were associated with pupillary abnormality, clinical progression, the number and volume of TEDH, and midline shift. Although the outcome was excellent in most cases, early diagnosis and surgical evacuation before irreversible brain damage was important to lower mortality for those massive TEDHs.

Our experience with surgically treated epidural hematomas in children

OBJECTIVE

Traumatic epidural hematomas (EDHs) in children are a relatively unusual occurrence. The cause and outcome vary depending on period and region of study. The aims of this analysis were to review the cause and outcome of pediatric EDHs nowadays and to discuss outcome-related variables in a large consecutive series of surgically treated EDH in children.

METHODS

This is a retrospective review of 29 patients with surgically treated EDHs between Jan 2000 and February 2010. Patients' medical records, computed tomographic (CT) scans, and, if performed, magnetic resonance imaging (MRI) were reviewed to define variables associated with outcome. Variables included in the analysis were age, associated severe extracranial injury, abnormal pupillary response, hematoma thickness, severity of head injury (Glasgow Coma Scale score), parenchymal brain injury, and diffuse axonal injury.

RESULTS

The mean (SD) age of the patients was 109 months (0-185 months). Most of the injuries with EDHs occurred in traffic accident (14 cases, 48.2%) and followed by slip down in 6 cases and falls in 6 cases. There were one birth injury and one unknown cause. EDHs in traffic accidents occurred in pedestrians hit by a motor vehicle, 9 cases; motorbike and car accidents, 5 cases and bicycle accidents, 1 case. The locations of hematoma were almost same in both sides (left side in 15 cases). Temporal lobe is the most common site of hematomas (13 cases, 44%). The mean size of the EDHs was 18 mm (range, 5-40 mm). Heterogeneous hematomas in CT scans were 20 cases (67%). Two patients were referred with unilateral or bilateral dilated pupil(s). There was enlargement of EDH in 5 patients (17%). All of them were heterogeneous hematomas in CT scans. Except for 4 patients, all EDHs were associated with skull fracture(s) (87%). There was no case of patient with major organ injury. CT or MRI revealed brain contusion in 5 patients, and diffuse axonal injury in one patient. The mortality was zero, and the outcomes were excellent in 26 and good in 2 patients. None of the tested variables were found to have a prognostic relevance.

CONCLUSION

Regardless of the EDH size, the clinical status of the patients, the abnormal pupillary findings, or the cause of injury, the outcome and prognosis of the patients with EDH were excellent.
