Surgical management of traumatic extradural hematomas in children: an analysis of 201 patients at a tertiary neurosurgical center

Temporal Delays in the Management of Traumatic Brain Injury: A Comparative Meta-Analysis of Global Literature

OBJECTIVE

A meta-analysis was conducted to compare: 1) time from traumatic brain injury (TBI) to the hospital, and 2) time within the hospital to intervention or surgery, by country-level income, World Health Organization region, and healthcare payment system.

METHODS

A comprehensive literature search was conducted and followed by a meta-analysis comparing duration of delays (prehospital and intrahospital) in TBI management. Means and standard deviations were pooled using a random effects model and subgroup analysis was performed using R software.

RESULTS

Our analysis comprised 95,554 TBI patients from 45 countries.

BY COUNTRY-LEVEL INCOME

From 23 low- and middle-income countries, a longer mean time from injury to surgery (862.53 minutes, confidence interval [CI]: 107.42-1617.63), prehospital (217.46 minutes, CI: -27.34-462.25), and intrahospital (166.36 minutes, 95% CI: 96.12-236.60) durations were found compared to 22 high-income countries.

BY WHO REGION

African Region had the greatest total (1062.3 minutes, CI: -1072.23-3196.62), prehospital (256.57 minutes [CI: -202.36-715.51]), and intrahospital durations (593.22 minutes, CI: -3546.45-4732.89).

BY HEALTHCARE PAYMENT SYSTEM

Multiple-Payer Health Systems had a greater prehospital duration (132.62 minutes, CI: 54.55-210.68) but greater intrahospital delays were found in Single-Payer Health Systems (309.37 minutes, CI: -21.95-640.69).

CONCLUSION

Our study concludes that TBI patients in low- and middle-income countries within African Region countries face prolonged delays in both prehospital and intrahospital management compared to high-income countries. Additionally, patients within Single-Payer Health System experienced prolonged intrahospital delays. An urgent need to address global disparities in neurotrauma care has been highlighted.

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.

Clinico-radiological correlation with outcome in acute epidural haematoma: a tertiary centre experience from Nepal

Background

Epidural haematoma (EDH) accounts for up to 15% of severe traumatic brain injury (TBI) cases and remains the most common cause of mortality and disability. Several clinical and radiological factors affect patient outcomes. This study aims to correlate patients' clinical and radiological profiles with acute EDH outcomes.

Methods

A retrospective, single-centred, consecutive case series was conducted on the patients diagnosed with an acute EDH admitted to Tribhuvan University Teaching Hospital (TUTH) between May 2019 and April 2023. The modified Rankin scale (mRS) was used to assess the outcome. Univariate analysis and Kruskal-Wallis H test with Dunn-Bonferroni post-hoc test was conducted.

Results

There were 107 patients diagnosed with EDH, of which 52.3% were less than 20 years old with male preponderance. Falls were the most common mechanism of injury (64.5%), and most cases were referred to, not brought directly. The majority had a GCS score greater than or equal to 13 (85%) at presentation, and only 5.5% had a GCS score less than or equal to 8. According to the mRS, most patients had favourable outcomes, with 88.7% having no significant disability and 11.3% having a slight disability.

Conclusion

This case series is the largest and most recent report from Nepal and demonstrated that GCS, pupillary response, skull fracture, neurological symptoms, pre-hospital and intra-hospital delay, and management modalities are critical factors in determining the total hospital and ICU stay but did not have an impact on the mRS scores.

Factors Delaying the Continuum of Care for the Management of Traumatic Brain Injury in Low- and Middle-Income Countries: A Systematic Review

BACKGROUND

Considering the disproportionate burden of delayed traumatic brain injury (TBI) management in low- and middle-income countries (LMICs), there is pressing demand for investigations. Therefore, our study aims to evaluate factors delaying the continuum of care for the management of TBIs in LMICs.

METHODS

A systematic review was conducted with PubMed, Scopus, Google Scholar and Cumulative Index to Nursing and Allied Health Literature (CINAHL). Observational studies with TBI patients in LMIC were included. The factors affecting management of TBI were extracted and analyzed descriptively.

RESULTS

A total of 55 articles were included consisting of 60,603 TBI cases from 18 LMICs. Road traffic accidents (58.7%) were the most common cause of injury. Among included studies, factors contributing to prehospital delays included a poor referral system and lack of an organized system of referral (14%), long travel distances (11%), inadequacy of emergency medical services (16.6%), and self-treatment practices (2.38%). For in-hospital delays, factors such as lack of trained physicians (10%), improper triage systems (20%), and absence of imaging protocols (10%), lack of in-house computed tomography scanners (35%), malfunctioning computed tomography scanners (10%), and a lack of invasive monitoring of intracranial pressure (5%), limited theater space (28%), lack of in-house neurosurgical facilities (28%), absence of in-house neurosurgeons (28%), and financial constraints (14%) were identified.

CONCLUSIONS

Several factors, both before and during hospitalization contribute to delays in the management of TBIs in LMICs. Strategically addressing these factors can help overcome delays and improve TBI management in LMICs.

Outcomes of Evacuating Subacute Extradural Hematoma Through a Minicraniectomy: A 5-Year Study

Background Extradural hematoma (EDH) is a hematoma between the dura and the inner surface of the skull, found in 1 to 3% of all head-injured patients, rising to 9% among the unconscious ones. It is said to be subacute when about 2 to 4 days old. Further enlargement of the burr hole to about 3 to 5 cm wide (minicraniectomy) may allow its total evacuation.

Objective To recommend it as a treatment option, this study aims to evaluate the surgical outcomes of evacuating a subacute EDH through a minicraniectomy.

Method This was a 5-year prospective study in a Nigerian tertiary health institution.

Results In total, 108 patients, consisting of 96 males and 12 females with a male to female ratio of 8:1 were included. Their ages ranged from 10 to 69 years. Etiologies were road traffic accident (RTA, 73.2%), assault (18.5%), and falls (8.3%). Hematoma ages were 2 days (61.1%), 3 days (25%), 4 days (13.9%). GCS were mild (11%), moderate (56%), and severe (33%). Locations were right-sided (59.3%), left-sided (40.7%) with 73.1% in parietotemporal area. Active bleeding was encountered in 15% only. Postoperative complications were seizure (13.9%), death (12%), and surgical site infection (4.6%) among others. Outcomes at 2 weeks were good (83, 76.9%), moderate disability (12, 11.1%), severe disability (10, 9.3%), vegetative (1, 0.9%), and death (2, 1.9%).

Conclusion Considering the significant morbidity and mortality and the need for urgent interventions in EDH, most patients presenting in the subacute acute (2– 4 days) stage can be evacuated via a minicraniectomy with good outcomes.

Role of routine post-operative CT brain following evacuation of extradural haematoma in children: a single-centre experience

PURPOSE

Extradural haematoma (EDH) is a serious neurosurgical emergency in children, which confers significant morbidity and mortality rates. The objective of this study was to retrospectively evaluate the role of post-operative imaging in children with EDH who were managed surgically in a national paediatric neurosurgical unit over a 9-year period (January 2008 to December 2016).

METHODS

A retrospective case review of paediatric patients who underwent surgical evacuation of extradural haematoma between January 2008 and December 2016 was performed. This included demographic and clinical details, indications for post-operative imaging and outcomes.

RESULTS

Seventy patients underwent surgical management of EDH during this time period, with a male preponderance (69%) and a mean age of 8 years. The commonest location of haematoma in this cohort was in the parietal region (n = 24), with a mean maximum thickness of 25.9 mm and mean volume of 57 ml. Post-operative imaging was performed in 84% of patients. However, only one patient had a change in the course of their post-operative management as a result of post-operative imaging findings.

CONCLUSIONS

Post-operative imaging in asymptomatic paediatric patients after evacuation of EDH could therefore be avoided as a routine investigation.

Surgical outcomes of Supra- Infra Tentorial Extradural Hematoma (SIEDH): A retrospective study from a single institution

INTRODUCTION

Bicompartmental Supra plus Infratentorial Extra Dural Hematoma (SIEDH) is an uncommon yet important category of Extradural Hematoma (EDH) straddling the transverse sinus. It requires quick decision making and proper surgical evacuation.

METHODS

We did a retrospective chart review of all SIEDH cases from prospectively maintained operative database in our institute between 2011 & 2017. Clinical status at discharge and follow up were used to assess outcome. Ordinal regression analysis was used for analysis of factors predicting the outcome. We also describe the surgical procedure we follow at our high-volume trauma center for this unique entity.

RESULTS

We had 61 operated cases of SIEDH in our series. The median age of the cohort was 30 years (IQR: 21.5-42). Road Traffic Accident was the most common mode of injury (67.2 %). Median pre-operative GCS was 12 (IQR: 9-12). The median volume of SIEDH was 50cc (IQR: 40-70). Mass effect on 4^thventricle and brainstem was seen in 47 and 34 patients respectively. An associated fracture was seen in 54 patients. Sinus injury related bleed was noted intra-operatively in 57 % (N = 35). Follow up was available for 60 cases with a median of 130 days. On evaluating with ordinal regression analysis, we found that, the GCS at presentation, pupillary asymmetry, volume of SIEDH, infratentorial volume, blood loss and mass effect on 4^thventricle were statistically significant factors affecting GCS at discharge. However, the GCS at presentation, infratentorial volume and blood loss were the only factors determining GOS at follow-up.

CONCLUSION

SIEDH are uncommon yet important type of injury type which requires prompt attention and appropriate nuanced approach. Large SIEDH are commonly associated with sinus injury, and large volume blood loss may be anticipated. In addition, SIEDH may be associated with other traumatic brain injuries which may require surgical evacuation.
