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

Intracranial Intraosseous Catheter Placement to Temporize an Epidural Hematoma

Acute epidural hematomas can lead to rapid neurologic decompensation and death. Epidural hematomas may require emergency surgical clot removal, but many patients live far away from a trauma center. This case report describes a pediatric patient with an acute epidural hematoma with significant neurologic compromise who initially presented to a nontrauma center. The emergency department (ED) had no neurosurgeon or equipment to perform burr hole craniostomy. The emergency physician at the nontrauma ED inserted an intraosseous catheter intracranially to temporarily decompress the hematoma due to long transport times. The patient survived with complete neurologic recovery. This is the youngest known patient in whom an intraosseous catheter was used to drain an intracranial hematoma.

Emergency department burr hole simulation using 3D-printed model

BACKGROUND

Traumatic epidural hematoma (EDH) with the potential to displace the brain tissue and increase intracranial pressure (ICP), is a life-threatening condition that requires emergent intervention. In rare circumstances, Emergency Physician (EP) may have to do skull trephination to reduce the ICP as a temporary measure.

SPECIFIC AIMS

To evaluate emergency medicine (EM) residents' comfort in performing emergency department (ED) burr holes and to assess their difficulties and evaluate comfort level before and after simulated EDH cases.

MATERIALS AND METHODS

A 3D-printed skull and electrical and manual drills were used for the simulation. Subjective comfort level pre and post-procedure, as well as objective procedural skills and time to complete the drill, were recorded.

RESULTS

Twenty EM residents participated in the simulation study. The median time to perforate through the skull was 4 s for the electric drill and 10 s for the manual drill. A comfort level of 5 and above was reported by 12 participants for the manual drill and by 17 participants for the electric drill. Six participants had mild and 2 participants had moderate observed difficulty in handling the manual and electric drill. Most participants performed both procedures successfully with one attempt only. Three participants have an overall comfort level above 5 before the simulation and 13 participants had a post-simulation.

CONCLUSION

The 3D-printed model assisted the ED burr hole simulation and the residents could perform the procedure with minimum difficulties.

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.

Application of Absolute Alcohol in the Treatment of Traumatic Intracranial Hemorrhage via Interventional Embolization of Middle Meningeal Artery

Background: Traumatic brain injury is a common condition in neurosurgery. Traditional methods of treatment include conservative treatment and surgical evacuation using burr-holes or craniotomy; however, studies have reported problems such as high re-expansion rates after conservative treatment of epidural hematoma and high postoperative recurrence rates of subdural hematoma. Solutions to these problems are lacking, and research into new treatment methods is ongoing. Among the potential new treatments, middle meningeal arterial embolization is an option. This study involved patients with acute epidural hematoma and chronic subdural hematoma. The purpose was to evaluate the use and effects of absolute alcohol to embolize the middle meningeal artery to treat intracranial hematoma. Material and Methods: A retrospective description study was 12 cases of intracranial hematoma who treated with absolute alcohol interventional therapy from our hospital between June 2018 and October 2019. Five patients with acute epidural hematoma and seven patients with chronic subdural hematoma were treated using absolute alcohol to embolize the middle meningeal artery. Patients' clinical data, imaging results, surgical results, and prognosis were recorded and analyzed. Results: All patients underwent absolute alcohol embolization of the middle meningeal artery, in combination with burr-hole drainage. All imaging data were confirmed preoperatively. We successfully used absolute alcohol to embolize the middle meningeal artery intraoperatively and confirmed these results by postoperative angiography. All patients achieved symptomatic relief without complications, and no recurrence or re-expansion was seen with follow-up computed tomography. Our study has been registered in the Chinese Clinical Trial Registry (http://www.chictr.org.cn, ChiCTR1800018714). Conclusion: The use of absolute alcohol to embolize the middle meningeal artery could be used as an attempt to treat acute epidural hematoma and chronic subdural hematoma.

Decompression of Subdural Hematomas Using an Intraosseous Needle in the Emergency Department: A Case Series

Introduction

Traumatic subdural hematomas beget significant morbidity and mortality if not rapidly decompressed. This presents a unique challenge to the emergency physician without immediate neurosurgical support.

Case Report

We report two cases of patients in Los Angeles County with traumatic subdural hematomas and clinical deterioration in the emergency department (ED) who were treated with decompression using an intraosseous needle drill.

Discussion

We believe these cases represent the first use of this technique to temporize a subdural hematoma in the ED.

Bedside Craniostomy and Serial Aspiration with an Intraosseous Drill/Needle to Temporize an Acute Epidural Hemorrhage with Mass Effect

BACKGROUND

This report describes a technique for an immediate mechanical intervention using a familiar tool for emergency physicians and trauma surgeons to temporize acute epidural bleeding with mass effect. The Monro-Kellie Doctrine suggests that immediate removal of some blood will reduce intracranial pressure and mitigate some of the deleterious effects until the neurosurgeon can respond.

CASE DESCRIPTION

A 38-year-old male with active extradural hemorrhage and expanding hemtoma with mass effect and herniation was treated at the bedside with an intraosseous drill to perform craniostomy and allow serial aspirations of continued bleeding.

CONCLUSIONS

Bedside craniosotmy with an intraosseous drill can allow for immediate temporizing of a large epidural hemorrhage and be applied by emergency physicians and/or trauma specialists when neurosurgical consultation is delayed. Serial aspirations should be performed when hemorrhage is ongoing and until definitive evacuation is performed.

Cranial burr holes in the emergency department: to drill or not to drill?

The practice of trepanning (referred to today as a craniotomy) dates back to the Neolithic period. Reasons for drilling a hole through the skull evolved from releasing evil spirits and curing insanity to practical management of head injuries in ancient Greece and Rome. Today, craniotomy or drilling a burr hole through the skull is very much the purview of the neurosurgeon. Yet one could argue that the procedure itself is more 'bone surgery' than 'brain surgery'. Nevertheless, despite the fact that head injury is a common presentation at district general hospitals and traumatic extra-axial haemorrhages are encountered often, the straightforward skillset required to drill a burr hole as a pretransfer, temporising, life-saving measure is seldom taught and has never gained traction. What we advocate in this article is the adaptation and novel application of an old, tried and tested technique in new hands. The critical pathophysiological turning point of any expanding extra-axial haemorrhage is the inflection point on the volume/Intracranial pressure (ICP) curve beyond which compensation is impossible. The subsequent rising ICP initiates a predictable continuum of clinical signs signalling progressive herniation. There are few emergencies as time-critical as a patient with an isolated, expanding extradural haemorrhage embarking on a trajectory of rostrocaudal deterioration and inevitable death. In many cases, the tragedy is compounded by the knowledge that such a patient probably has a healthy underlying brain, often evidenced by a lucid period after trauma. Our emergency department is attached to a small 300-bed District General Hospital (DGH) on the rural North West coast of Ireland. We are 262 km distant by road from a national neurosciences department that can, at best, be reached in 2 hours and 30 min. Quality improvement review of years of dismal outcomes in patients such as those described earlier with potentially remediable pathology prompted research and development of the skillset we are now able to offer, an old technique in new hands.

Temporising an extradural haematoma by intraosseous needle craniostomy in the District General Hospital by non-neurosurgical doctors - A case report

We report the case of a 69-year-old man admitted to the emergency department of a UK district general hospital with an extradural haematoma following closed head injury. He deteriorated rapidly before transfer to the regional neurosurgical centre and was treated with decompression of the extradural haematoma through an EZ-IO™ intraosseous needle in our department, with telephone guidance from the neurosurgeon. We believe this to be the first reported use of this technique in a district general hospital.

Novel Minimally Invasive Treatment Strategy for Acute Traumatic Epidural Hematoma: Endovascular Embolization Combined with Drainage Surgery and Use of Urokinase

BACKGROUND

Hematoma evacuation is regular treatment for acute traumatic epidural hematoma (ATEDH) patients meeting with surgery indications. However, it is an invasive approach performed under general anesthesia. Here, a novel minimally invasive method of endovascular embolization with subsequent drainage surgery and use of urokinase was established to treat ATEDH under local anesthesia.

METHODS

A novel minimally invasive method of endovascular embolization with subsequent drainage surgery and use of urokinase was established to treat ATEDH under local anesthesia. Firstly, 23 ATEDH patients with hematomas in the temporal area underwent digital subtraction angiography detecting the bleeding point. Next, embolization was performed. After embolization, drainage surgery was taken and urokinase was injected into the hematoma cyst by drainage tube to lyse hematoma twice per day.

RESULTS

The results showed that the middle meningeal artery was the bleeding source. Embolization immediately ceased bleeding. Most clots were resolved and drained after treatment. No recurrence of hematoma or infection was observed.

CONCLUSION

The findings suggest that the combined treatments can be an alternative minimally invasive option for ATEDHs, especially for elderly patients or those contraindicated for general anesthesia.

Efficacy of decompressive craniectomy in the management of intracranial pressure in severe traumatic brain injury

Traumatic brain injury (TBI) is a common cause of permanent disability for which clinical management remains suboptimal. Elevated intracranial pressure (ICP) is a common sequela following TBI leading to death and permanent disability if not properly managed. While clinicians often employ stepwise acute care algorithms to reduce ICP, a number of patients will fail medical management and may be considered for surgical decompression. Decompressive craniectomy (DC) involves removing a component of the bony skull to allow cerebral tissue expansion in order to reduce ICP. However, the impact of DC, which is performed in the setting of neurological instability, ongoing secondary injury, and patient resuscitation, has been challenging to study and outcomes are not well understood. This review summarizes historical and recent studies to elucidate indications for DC and the nuances, risks and complications in its application. The pathophysiology driving ICP elevation, and the corresponding medical interventions for their temporization and treatment, are thoroughly described. The current state of DC - including appropriate injury classification, surgical techniques, concurrent medical therapies, mortality and functional outcomes - is presented. We also report on the recent updates from large randomized controlled trials in severe TBI (Decompressive Craniectomy [DECRA] and Randomized Evaluation of Surgery with Craniectomy for Uncontrollable Elevation of ICP [RESCUEicp]), and recommendations for early DC to treat refractory ICP elevations in malignant middle cerebral artery syndrome. Limitations for DC, such as the equipoise between immediate reduction in ICP and clinically meaningful functional outcomes, are discussed in support of future investigations.

Trephination mini-craniectomy for traumatic posterior fossa epidural hematomas in selected pediatric patients

PURPOSE

Posterior fossa epidural hematomas (PFEDH) are uncommon in children but usually require timely surgical intervention due to the risk of life-threatening brainstem compression. We attempt to make the surgical procedure less invasive by treating selected pediatric patients with trephination mini-craniectomy.

METHODS

We retrospectively reviewed the clinical courses, radiological findings, surgical procedures, and prognoses of the pediatric patients who were treated in our departments for traumatic PFEDH from January 2010 to January 2015.

RESULTS

During this period, a total of 17 patients were surgically treated for PFEDH and 7 were managed with trephination mini-craniectomy for hematoma evacuation. The outcomes were good in all 7 patients as evaluated with Glasgow Outcome Score. There was no mortality in this series. The on average 30-month clinical follow-up showed that patients experienced satisfactory recoveries without complications.

CONCLUSION

Our results suggest that trephination mini-craniectomy is a safe surgical technique for selected PFEDH patients with moderate hematoma volume and stabilized neurological functions. However, standard craniectomy is recommend when there are rapid deteriorations in patients' neurological functions or the hematomas are large and exerted severe mass effects.

Novel Clinical Scale for Evaluating Pre-Operative Risk of Cerebral Herniation from Traumatic Epidural Hematoma

Secondary massive cerebral infarction (MCI) is the predominant prognostic factor for cerebral herniation from epidural hematoma (EDH) and determines the need for decompressive craniectomy. In this study, we tested the clinical feasibility and reliability of a novel pre-operative risk scoring system, the EDH-MCI scale, to guide surgical decision making. It is comprised of six risk factors, including hematoma location and volume, duration and extent of cerebral herniation, Glasgow Coma Scale score, and presence of preoperative shock, with a total score ranging from 0 to 18 points. Application of the EDH-MCI scale to guide surgical modalities for initial hematoma evacuation surgery for 65 patients (prospective cohort, 2012.02-2014.01) showed a significant improvement in the accuracy of the selected modality (95.38% vs. 77.95%; p = 0.002) relative to the results for an independent set of 126 patients (retrospective cohort, 2007.01-2012.01) for whom surgical modalities were decided empirically. Results suggested that simple hematoma evacuation craniotomy was sufficient for patients with low risk scores (≤9 points), whereas decompressive craniectomy in combination with duraplasty were necessary only for those with high risk scores (≥13 points). In patients with borderline risk scores (10-12 points), those having unstable vital signs, coexistence of severe secondary brainstem injury, and unresponsive dilated pupils after emergent burr hole hematoma drainage had a significantly increased incidence of post-traumatic MCI and necessity of radical surgical treatments. In conclusion, the novel pre-operative risk EDH-MCI evaluation scale has a satisfactory predictive and discriminative performance for patients who are at risk for the development of secondary MCI and therefore require decompressive craniectomy.

Current approaches to the treatment of head injury in children

Head trauma is one of the most challenging fields of traumatology and demands immediate attention and intervention by first-line clinicians. Symptoms can vary from victim to victim and according to the victim's age, leading to difficulties in making timely and accurate decisions at the point of care. In children, falls, accidents while playing, sports injuries, and abuse are the major causes of head trauma. Traffic accidents are the main cause of disability and death in adolescents and adults. Injury sites include facial bones, muscles, ligaments, vessels, joints, nerves, and focal or whole-brain injuries. Of particular importance are cranial and intracranial injuries. A closed injury occurs when the head suddenly and violently hits an object but the object does not break through the skull. A penetrating injury occurs when an object pierces the skull and affects the brain tissue. Early diagnosis and proper management are crucial to treat patients with potentially life-threatening head and neck trauma. In this review, we discuss the different cases of traumatic brain injury and summarize the current therapies and neuroprotective strategies as well as the related outcomes for children with traumatic brain injury.

The exploratory burr hole: indication and results at one departmental hospital of benin

Objective. The aim of this study was to describe the indications and results of exploratory burr hole performed at the Departmental Teaching Hospital of Borgou (Benin). Methods. It was a retrospective study performed from January 2008 to February 2011. It concerned patients with a closed traumatic brain injury (TBI) in which an exploratory burr hole was performed. The selection criteria were unilateral mydriasis associated with neurological deficits on the opposite side or the occurrence of a decreased consciousness associated with the appearance of a motor deficit after a lucid interval. Results. Amongst the 74 patients operated, 23 (31%) underwent an exploratory burr hole for which the average age was 24.8 ± 17.3 years. Sex ratio male/female was 3.6. TBI was due to road traffic accident (56.5%), a fall (26.1%), and an assault (17.4%). It was severe (47.8%), moderate (39.1%), and mild (13.1%). Mydriasis was observed in 69.6% of cases as well as neurological deficit in all patients. A lesion was observed in 15 (65.2%) cases. Conclusion. The exploratory burr hole seemed as an old practice, still no longer performed in full practice in Benin, and is a diagnosis and therapeutic approach. Better technical conditions would allow more relevant therapeutic options.

The surgical outcome of traumatic extra-axial hematomas causing brain herniation in children

AIM

The aim of this study was to assess the surgical outcome and prognostic importance of clinical and radiological data from children operated on under emergency conditions due to an extra-axial hematoma causing brain herniation.

METHODS

This retrospective study included 25 children operated on due to herniated traumatic extra-axial hematomas from January 2000 to December 2010.

RESULTS

Of those 25 children, 17 (68%) were diagnosed with subdural hematoma (SDH), 7 (28%) with epidural hematoma (EDH) and only 1 patient (4%) suffered from both SDH and EDH. Overall mortality from a herniated extra-axial hematoma was 44%. The mortality rate for herniated SDH patients was 52.9%, and only 1 patient died from a herniated EDH (14.2%). Low Glasgow coma scale scores at admission, high postoperative intracranial pressure (ICP) values, longer intervals from trauma to surgery, longer durations of brain herniation, the presence of intraoperative brain swelling, larger and thicker hematomas and more displacement of the midline structures and obliteration of the basal cisterns were all correlated with mortality and an unfavorable outcome.

CONCLUSIONS

Brain herniation is a serious consequence of traumatic extra-axial hematomas in children, and approximately one third of these patients have the potential for a favorable outcome. We recommend postoperative ICP monitoring to predict outcome and early decompressive surgery when possible for promising results.
