Utility of Routine Surveillance Head Computed Tomography After Receiving Therapeutic Anticoagulation in Patients with Acute Traumatic Intracranial Hemorrhage.

INTRODUCTION: Patients with traumatic intracranial hemorrhage (tICH) are at increased risk of venous thromboembolism and may require anticoagulation. We evaluated the utility of surveillance computed tomography (CT) in patients with tICH who required therapeutic anticoagulation. METHODS: This single institution, retrospective study included adult patients with tICH who required anticoagulation within 4 weeks and had a surveillance head CT within 24 hours of reaching therapeutic anticoagulation levels. The primary outcome was hematoma expansion (HE) detected by the surveillance CT. Secondary outcomes included 1) changes in management in patients with HE on the surveillance head CT, 2) HE in the absence of clinical changes, and 3) mortality due to HE. We also compared mortality between patients who did and did not have a surveillance CT. RESULTS: Of 175 patients, 5 (2.9%) were found to have HE. Most (n = 4, 80%) had changes in management including anticoagulation discontinuation (n = 4), reversal (n = 1), and operative management (n = 1). Two patients developed symptoms or exam changes prior to the head CT. Of the 3 patients (1.7%) without preceding exam changes, each had only very minor HE and did not require operative management. No patient experienced mortality directly attributed to HE. There was no difference in mortality between patients who did and those who did not have a surveillance scan. CONCLUSIONS: Our findings suggest that most patients with tICH who are started on anticoagulation could be followed clinically, and providers may reserve CT imaging for patients with changes in exam/symptoms or those who have a poor clinical examination to follow.

The Effect of 4-Factor Prothrombin Complex Concentrate to Reverse Factor Xa Inhibitors in Patients With Traumatic Intracranial Hemorrhage.

The utility of 4-factor prothrombin complex concentrate (4F-PCC) for reversal in patients on factor Xa inhibitors (XaI) is unclear, specifically in mild traumatic brain injury (mTBI). This is a retrospective review over 6 years at a level 1 trauma center of patients presenting with mTBI on XaI comparing outcomes for those that received 4F-PCC to those that did not. 140 patients were included, 103 (74%) of these patients received 4F-PCC while 37 (26%) did not. There was no significant difference in neurologic decline within 48 hours of admission or need for neurosurgical intervention. Interestingly, there was no difference in ICH progression (16% vs 14%, P = .77). In this study, 4F-PCC given after mild traumatic brain injury did not impact ICH progression, neurologic decline, or need for neurosurgical intervention. Although limited in numbers, this study suggests that 4F-PCC is not necessarily required in mTBI and further studies are indicated.

Traumatic intracranial hemorrhage in pediatrics: Implications of factor XIII deficiency and consumptive coagulopathy in abusive head trauma evaluation.

For infants that present with intracranial hemorrhage in the setting of suspected abusive head trauma (AHT), the standard recommendation is to perform an evaluation for a bleeding disorder. Factor XIII (FXIII) deficiency is a rare congenital bleeding disorder associated with intracranial hemorrhages in infancy, though testing for FXIII is not commonly included in the initial hemostatic evaluation. The current pediatric literature recognizes that trauma, especially traumatic brain injury, may induce coagulopathy in children, though FXIII is often overlooked as having a role in pediatric trauma-induced coagulopathy. We report an infant that presented with suspected AHT in whom laboratory workup revealed a decreased FXIII level, which was later determined to be caused by consumption in the setting of trauma induced coagulopathy, rather than a congenital disorder. Within the Child Abuse Pediatrics Research Network (CAPNET) database, 85 out of 569 (15 %) children had FXIII testing, 3 of those tested (3.5 %) had absent FXIII activity on qualitative testing, and 2 (2.4 %) children had activity levels below 30 % on quantitative testing. In this article we review the literature on the pathophysiology and treatment of low FXIII in the setting of trauma. This case and literature review demonstrate that FXIII consumption should be considered in the setting of pediatric AHT.

Evaluating CAPO®: A biocompatibility, transparency, and fitment assessment for use with CEREBO® in traumatic intracranial injury detection.

Healthcare-associated infections (HAIs) are a global concern affecting millions of patients, requiring robust infection prevention and control measures. In particular, patients with traumatic brain injury (TBI) are highly susceptible to nosocomial infections, emphasizing the importance of infection control. Non-invasive near infrared spectroscopy (NIRS) device, CEREBO® integrated with a disposable component CAPO® has emerged as a valuable tool for TBI patient triage and this study evaluated the safety and efficacy of this combination. Biocompatibility tests confirmed safety and transparency assessments demonstrated excellent light transmission. Clinical evaluation with 598 enrollments demonstrated high accuracy of CEREBO® in detecting traumatic intracranial hemorrhage. During these evaluations, the cap fitted well and moved smoothly with the probes demonstrating appropriate flexibility. These findings support the efficacy of the CAPO® and CEREBO® combination, potentially improving infection control and enhancing intracranial hemorrhage detection for TBI patient triage. Ultimately, this can lead to better healthcare outcomes and reduced global HAIs.

Outcome of Nonoperative Management of Selected Cases of Acute Traumatic Intracranial Hematomas in a Rural Neurosurgical Service of a Developing Country.

OBJECTIVE: In resource-limited settings, the standard of care prescribed in developed countries for either operative or nonoperative management of traumatic intracranial hematomas (TICHs) frequently has to be adapted to the economic and infrastructural realities. This study aims to present the outcome of selected cases of TICHs managed nonoperatively without routine intensive care unit admission, repeated cranial computed tomography (CT) scan or intracranial pressure monitoring at a rural neurosurgical service in a developing country. METHODS: This was a retrospective analysis of a cohort of our patients with cranial CT-confirmed TICHs selected for nonoperative treatment from our prospective head injury (HI) register over a 42-month period. RESULTS: There were 67 patients (51 males) in this study with a mean age of 38.6 (standard deviation, 17.6) years, having mild HI in >half, (55.2%, 37/67) and anisocoria in 22.4% (15/67). Road traffic accident was the most common (50/67, 74.7%) trauma etiology. Isolated acute-subdural hematoma, intracerebral hemorrhage, and epidural hematoma occurred in 29.9%, 25.4%, and 22.4% of the patients respectively. Only 2 of 8 patients in whom intensive care unit admission was deemed necessary could afford admission. Repeat cranial CT scan was requested in 8 patients (8/67, 11.9%); only 5 of these could afford the investigation. The outcome of care was good in 82.1% patients (55/67). Increasing severity of the HI (P < 0.01) and presence of pupillary abnormality (P = 0.03) were significant predictors of poor outcome. CONCLUSIONS: In a Nigerian rural neurosurgery practice, nonoperative management of a well-selected cohort of TICHs was attended by acceptable level of favorable outcome.

Diagnostic value of protein S100b as predictor of traumatic intracranial haemorrhage in elderly adults with low-energy falls: results from a retrospective observational study.

PURPOSE: The objectives of this study were to analyse the clinical value of protein S100b (S100b) in association with clinical findings and anticoagulation therapy in predicting traumatic intracranial haemorrhage (tICH) and unfavourable outcomes in elderly individuals with low-energy falls (LEF). METHODS: We conducted a retrospective study in the emergency department (ED) of the LMU University Hospital, Munich by consecutively including all patients aged ≥ 65 years presenting to the ED following a LEF between September 2014 and December 2016 and receiving an emergency cranial computed tomography (cCT) examination. Primary endpoint was the prevalence of tICH. Multivariate logistic regression models and receiver operating characteristics were used to measure the association between clinical findings, anticoagulation therapy and S100b and tICH. RESULTS: We included 2687 patients, median age was 81 years (60.4% women). Prevalence of tICH was 6.7% (180/2687) and in-hospital mortality was 6.1% (11/180). Skull fractures were highly associated with tICH (odds ratio OR 46.3; 95% confidence interval CI 19.3-123.8, p < 0.001). Neither anticoagulation therapy nor S100b values were significantly associated with tICH (OR 1.14; 95% CI 0.71-1.86; OR 1.08; 95% CI 0.90-1.25, respectively). Sensitivity of S100b (cut-off: 0.1 ng/ml) was 91.6% (CI 95% 85.1-95.9), specificity was 17.8% (CI 95% 16-19.6), and the area under the curve value was 0.59 (95% CI 0.54 - 0.64) for predicting tICH. CONCLUSION: In conclusion, under real ED conditions, neither clinical findings nor protein S100b concentrations or presence of anticoagulation therapy was sufficient to decide with certainty whether a cCT scan can be bypassed in elderly patients with LEF. Further prospective validation is required.

Is reversal of anticoagulants necessary in neurologically intact traumatic intracranial hemorrhage?

INTRODUCTION: Falls are the leading cause of injury in older individuals, with intracranial hemorrhage (ICH) being a common complication. Anticoagulants, such as vitamin K antagonist and direct oral anticoagulants, are increasingly utilized, and clinicians may question the necessity of reversal in patients with minor ICH, especially in the setting of increased risk of adverse events. This study aimed to identify a population of patients with minor traumatic ICH at low risk for poor-neurologic status where anticoagulant reversal may not improve outcomes. METHODS: This retrospective cohort study utilized data accessed from 35 trauma centers from 2018 to 2021. Patients included had a preinjury anticoagulant regimen, ICH due to blunt trauma, Glasgow Coma Scale score of 15, an Abbreviated Injury Scale (AIS) head score from 2 to 4, and an AIS of ≤1 for non-head regions within 24 h of hospital arrival. Patients were excluded if they required an emergent neurosurgical procedure or were on a preinjury purinergic-P2 receptor-12 protein (P2Y12) inhibitor. The primary outcome was the rate of in-hospital mortality or hospice. RESULTS: There were 654 patients on preinjury anticoagulation who were included with a minor traumatic ICH without neurologic deficits. Overall, 263 patients were reversed and 391 were not reversed. Twelve (4.6%) patients with in-hospital mortality or hospice were reversed compared with 19 (4.91%) patients who were not reversed (p = 0.861). A composite of hospital complications occurred in 21 (8%) reversed patients and 34 (8.7%) not reversed patients (p = 0.748). The average intensive care unit length of stay was 1.4 ± 3.4 days in the reversed group and 1.1 ± 1.8 days in the not reversed group (p = 0.069). CONCLUSION: This study found no difference in hospital outcomes between patients with minor traumatic ICH on oral anticoagulants who were neurologically intact that were reversed versus those who were not reversed. Further studies should continue to define the subset of traumatic ICH patients who may not require reversal of anticoagulation.

Cardiac surgery for a right atrial myxoma with traumatic intracranial hemorrhage: a case report.

BACKGROUND: The timing of cardiac surgery with cardiopulmonary bypass (CPB) for intracranial hemorrhage is controversial. CASE PRESENTATION: We report the case of an 82-year-old woman who was transferred to our hospital because of a head injury. Brain computed tomography (CT) revealed traumatic intracranial hemorrhage, and transthoracic echocardiography revealed a giant right atrial myxoma. After confirming the disappearance of intracranial hemorrhage on brain CT, cardiac surgery with CPB was performed, which was uneventful. CONCLUSIONS: For an uneventful surgery, the optimal timing of cardiac surgery with CPB in patients with giant right atrial myxoma and intracranial hemorrhage should be based on brain CT.

Impact of premorbid oral anticoagulant use on survival in patients with traumatic intracranial hemorrhage.

OBJECTIVE: Although oral anticoagulant use has been implicated in worse outcomes for patients with a traumatic brain injury (TBI), prior studies have mostly examined the use of vitamin K antagonists (VKAs). In an era of increasing use of direct oral anticoagulants (DOACs) in lieu of VKAs, the authors compared the survival outcomes of TBI patients on different types of premorbid anticoagulation medications with those of patients not on anticoagulation. METHODS: The authors retrospectively reviewed the records of 1186 adult patients who presented at a level I trauma center with an intracranial hemorrhage after blunt trauma between 2016 and 2022. Patient demographics; comorbidities; and pre-, peri-, and postinjury characteristics were compared based on premorbid anticoagulation use. Multivariable Cox proportional hazards regression modeling of mortality was performed to adjust for risk factors that met a significance threshold of p < 0.1 on bivariate analysis. RESULTS: Of 1186 patients with a traumatic intracranial hemorrhage, 49 (4.1%) were taking DOACs and 53 (4.5%) used VKAs at the time of injury. Patients using oral anticoagulants were more likely to be older (p < 0.001), to have a higher Charlson Comorbidity Index (p < 0.001), and to present with a higher Glasgow Coma Scale (GCS) score (p < 0.001) and lower Injury Severity Score (ISS; p < 0.001) than those on no anticoagulation. Patients using VKAs were more likely to undergo reversal than patients using DOACs (53% vs 31%, p < 0.001). Cox proportional hazards regression demonstrated significantly increased hazard ratios (HRs) for VKA use (HR 2.204, p = 0.003) and DOAC use (HR 1.973, p = 0.007). Increasing age (HR 1.040, p < 0.001), ISS (HR 1.017, p = 0.01), and Marshall score (HR 1.186, p < 0.001) were associated with an increased risk of death. A higher GCS score on admission was associated with a decreased risk of death (HR 0.912, p < 0.001). CONCLUSIONS: Patients with a traumatic intracranial injury who were on oral anticoagulant therapy before injury demonstrated higher mortality rates than patients who were not on oral anticoagulation after adjusting for age, comorbid conditions, and injury presentation.

Administration of andexanet alfa for traumatic intracranial hemorrhage in the setting of massive apixaban overdose: A case report.

PURPOSE: Apixaban is a direct-acting oral anticoagulant that selectively inhibits factor Xa. Reversal strategies utilized to treat factor Xa inhibitor-associated bleeding include andexanet alfa, prothrombin complex -concentrate (PCC), and activated PCC (aPCC). The optimal treatment of traumatic intracranial hemorrhage in the setting of an apixaban overdose is unknown. SUMMARY: This case report describes a 69-year-old female who initially presented to an emergency department at a community hospital due to a ground-level fall with traumatic intracranial hemorrhage. The patient reportedly ingested apixaban 275 mg, carvedilol 250 mg, atorvastatin 1,200 mg, and unknown amounts of amlodipine and ethanol. Anti-inhibitor coagulant complex, an aPCC, was administered approximately 3 hours after presentation. Initial thromboelastography performed approximately 4 hours after presentation showed a prolonged reaction time of 16.8 minutes. Ongoing imaging and evidence of coagulopathy prompted repeated aPCC administration to a cumulative dose of approximately 100 U/kg. The patient underwent craniotomy with hematoma evacuation. Postoperative imaging showed expansion of the existing intracranial hemorrhage and new areas of hemorrhage. Andexanet alfa was administered approximately 18 hours after presentation, followed by repeat craniotomy with evacuation of the hematoma. No further expansion of the intracranial hemorrhage was observed, and the reaction time on thromboelastography was normalized at 6.3 minutes. CONCLUSION: This case suggests that andexanet alfa may have a role in the management of traumatic hemorrhage in the setting of an acute massive apixaban overdose. Use of andexanet alfa, PCC, and aPCC in this context requires further research.

Early surgery versus conservative treatment in patients with traumatic intracerebral hematoma: a CENTER-TBI study.

PURPOSE: Evidence regarding the effect of surgery in traumatic intracerebral hematoma (t-ICH) is limited and relies on the STITCH(Trauma) trial. This study is aimed at comparing the effectiveness of early surgery to conservative treatment in patients with a t-ICH. METHODS: In a prospective cohort, we included patients with a large t-ICH (< 48 h of injury). Primary outcome was the Glasgow Outcome Scale Extended (GOSE) at 6 months, analyzed with multivariable proportional odds logistic regression. Subgroups included injury severity and isolated vs. non-isolated t-ICH. RESULTS: A total of 367 patients with a large t-ICH were included, of whom 160 received early surgery and 207 received conservative treatment. Patients receiving early surgery were younger (median age 54 vs. 58 years) and more severely injured (median Glasgow Coma Scale 7 vs. 10) compared to those treated conservatively. In the overall cohort, early surgery was not associated with better functional outcome (adjusted odds ratio (AOR) 1.1, (95% CI, 0.6-1.7)) compared to conservative treatment. Early surgery was associated with better outcome for patients with moderate TBI and isolated t-ICH (AOR 1.5 (95% CI, 1.1-2.0); P value for interaction 0.71, and AOR 1.8 (95% CI, 1.3-2.5); P value for interaction 0.004). Conversely, in mild TBI and those with a smaller t-ICH (< 33 cc), conservative treatment was associated with better outcome (AOR 0.6 (95% CI, 0.4-0.9); P value for interaction 0.71, and AOR 0.8 (95% CI, 0.5-1.0); P value for interaction 0.32). CONCLUSIONS: Early surgery in t-ICH might benefit those with moderate TBI and isolated t-ICH, comparable with results of the STITCH(Trauma) trial.

Dual-energy computed tomography material decomposition improves prediction accuracy of hematoma expansion in traumatic intracranial hemorrhage.

OBJECTIVE: The angiographic spot sign (AS) on CT angiography (CTA) is known to be useful for predicting expansion in intracranial hemorrhage, but its use is limited due to its relatively low sensitivity. Recently, dual-energy computed tomography (DECT) has been shown to be superior in distinguishing between hemorrhage and iodine. This study aimed to evaluate the diagnostic performance of hematoma expansion (HE) using DECT AS in traumatic intracranial hemorrhage. METHODS: We recruited participants with intracranial hemorrhage confirmed via CTA for suspected traumatic cerebrovascular injuries. We evaluated AS on both conventional-like and fusion images of DECT. AS is grouped into three categories: intralesional enhancement without change, delayed enhancement (DE), and growing contrast leakage (GL). HE was evaluated by measuring hematoma size on DECT and follow-up CT. Logistic regression analysis was used to evaluate whether AS on fusion images was a significant risk factor for HE. Diagnostic accuracy was calculated, and the results from conventional-like and fusion images were compared. RESULTS: Thirty-nine hematomas in 24 patients were included in this study. Of these, 18 hematomas in 13 patients showed expansion on follow-up CT. Among the expanders, AS and GL on fusion images were noted in 13 and 5 hematomas, respectively. In non-expanders, 10 and 1 hematoma showed AS and GL, respectively. In the logistic regression model, GL on the fusion image was a significant independent risk factor for predicting HE. However, when AS was used on conventional-like images, no factors significantly predicted HE. In the receiver operating characteristic curve analysis, the area under the curve of AS on the fusion images was 0.71, with a sensitivity and specificity of 66.7% and 76.2%, respectively. CONCLUSIONS: GL on fusion images of DECT in traumatic intracranial hemorrhage is a significant independent radiologic risk factor for predicting HE. The AS of DECT fusion images has improved sensitivity compared to that of conventional-like images.

Systematic review on traumatic intracranial haemorrhage in patients on anti-thrombotic medications; haemorrhage progression, thrombosis, and anti-thrombotic recommencement.

A large number of patients who sustain a traumatic intracranial haemorrhage (tICH) are taking anti-thrombotic (AT) medications at the time of injury. These are stopped acutely, but there is uncertainty about safe timing for recommencement. This review aimed to understand the rate of new/progressive haemorrhage, thrombosis, and death in tICH patients on ATs and the rate and timing of AT recommencement. A systematic review of OVID Medline and EMBASE from 2000 to 2021 including adult patients with tICH on ATs with reported outcomes was performed. A total of 59 observational studies (20,421 patients) were included. Most patients were elderly (mean age 74), suffering falls (78%), and had a mild head injury. The mean new/progressive haemorrhage rate during admission was 26%, mostly diagnosed on routine imaging performed within 72 h of injury, with only 8% clinically significant. Thrombotic events were reported in 17 studies; mean rate of 3% during admission, 4-9% at 30 days and 3-11% at 6 months. AT recommencement rate and timing were only reported in six studies and varied widely, with some studies demonstrating reduced thrombotic events and mortality with earlier AT recommencement. Current data is observational and sparse in relation to haemorrhage, thrombosis, and AT recommencement. There is some suggestion that early recommencement, within 7-14 days, may be beneficial but higher quality studies with more consistent data are urgently required.

Early venous thromboembolism prophylaxis in patients with trauma intracranial hemorrhage: Analysis of the prospective multicenter Consortium of Leaders in Traumatic Thromboembolism study.

BACKGROUND: The optimal time to initiate venous thromboembolism prophylaxis (VTEp) for patients with intracranial hemorrhage (ICH) is controversial and must balance the risks of VTE with potential progression of ICH. We sought to evaluate the efficacy and safety of early VTEp initiation after traumatic ICH. METHODS: This is a secondary analysis of the prospective multicenter Consortium of Leaders in the Study of Thromboembolism study. Patients with head Abbreviated Injury Scale score of > 2 and with immediate VTEp held because of ICH were included. Patients were divided into VTEp ≤ or >48 hours and compared. Outcome variables included overall VTE, deep vein thrombosis (DVT), pulmonary embolism, progression of intracranial hemorrhage (pICH), or other bleeding events. Univariate and multivariate logistic regressions were performed. RESULTS: There were 881 patients in total; 378 (43%) started VTEp ≤48 hours (early). Patients starting VTEp >48 hours (late) had higher VTE (12.4% vs. 7.2%, p = 0.01) and DVT (11.0% vs. 6.1%, p = 0.01) rates than the early group. The incidence of pulmonary embolism (2.1% vs. 2.2%, p = 0.94), pICH (1.9% vs. 1.8%, p = 0.95), or any other bleeding event (1.9% vs. 3.0%, p = 0.28) was equivalent between early and late VTEp groups. On multivariate logistic regression analysis, VTEp >48 hours (odds ratio [OR], 1.86), ventilator days >3 (OR, 2.00), and risk assessment profile score of ≥5 (OR, 6.70) were independent risk factors for VTE (all p < 0.05), while VTEp with enoxaparin was associated with decreased VTE (OR, 0.54, p < 0.05). Importantly, VTEp ≤48 hours was not associated with pICH (OR, 0.75) or risk of other bleeding events (OR, 1.28) (both p = NS). CONCLUSION: Early initiation of VTEp (≤48 hours) for patients with ICH was associated with decreased VTE/DVT rates without increased risk of pICH or other significant bleeding events. Enoxaparin is superior to unfractionated heparin as VTE prophylaxis in patients with severe TBI. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Toward rational use of repeat imaging in children with mild traumatic brain injuries and intracranial injuries.

OBJECTIVE: Limited evidence exists on the utility of repeat neuroimaging in children with mild traumatic brain injuries (mTBIs) and intracranial injuries (ICIs). Here, the authors identified factors associated with repeat neuroimaging and predictors of hemorrhage progression and/or neurosurgical intervention. METHODS: The authors performed a multicenter, retrospective cohort study of children at four centers of the Pediatric TBI Research Consortium. All patients were ≤ 18 years and presented within 24 hours of injury with a Glasgow Coma Scale score of 13-15 and evidence of ICI on neuroimaging. The outcomes of interest were 1) whether patients underwent repeat neuroimaging during index admission, and 2) a composite outcome of progression of previously identified hemorrhage ≥ 25% and/or repeat imaging as an indication for subsequent neurosurgical intervention. The authors performed multivariable logistic regression and report odds ratios and 95% confidence intervals. RESULTS: A total of 1324 patients met inclusion criteria; 41.3% of patients underwent repeat imaging. Repeat imaging was associated with clinical change in 4.8% of patients; the remainder of the imaging tests were for routine surveillance (90.9%) or of unclear prompting (4.4%). In 2.6% of patients, repeat imaging findings were reported as an indication for neurosurgical intervention. While many factors were associated with repeat neuroimaging, only epidural hematoma (OR 3.99, 95% CI 2.22-7.15), posttraumatic seizures (OR 2.95, 95% CI 1.22-7.41), and age ≥ 2 years (OR 2.25, 95% CI 1.16-4.36) were significant predictors of hemorrhage progression and/or neurosurgery. Of patients without any of these risk factors, none underwent neurosurgical intervention. CONCLUSIONS: Repeat neuroimaging was commonly used but uncommonly associated with clinical deterioration. Although several factors were associated with repeat neuroimaging, only posttraumatic seizures, age ≥ 2 years, and epidural hematoma were significant predictors of hemorrhage progression and/or neurosurgery. These results provide the foundation for evidence-based repeat neuroimaging practices in children with mTBI and ICI.

Ultrasonic diagnosis of delayed hematoma during emergency removal of traumatic intracranial hematoma: A case report and literature review.

RATIONALE: It is emergency and vital during neurosurgical procedure in traumatic intracranial when an acute intraoperative brain bulge (AIBB) is occurred. It is important to get a diagnosis quickly. PATIENT CONCERNS: A 44-year-old man was undergone a neurosurgical procedure for the left side of traumatic intracranial hematoma. An AIBB was occurred during the surgery. Computed tomography (CT) is always used in diagnosis when an AIBB is occurred, but more time is needed when CT is conducted. DIAGNOSES: We diagnosed the AIBB through bedside real-time ultrasound, and a delayed hematoma which caused the AIBB was found. INTERVENTIONS: A further neurosurgical procedure of right intracranial hematoma was performed for the patient. OUTCOMES: The surgical effect and the patient's prognosis were significantly improved. LESSONS: Through this patient, we should pay more attention to the application of perioperative of real-time ultrasonic monitoring, to provide more convenience for surgical patients, and improve the prognosis of them.

Management of older adults after mild head trauma in an oral and maxillofacial surgery clinic.

PURPOSE: The primary aim was to determine the incidence of intracranial hemorrhage (ICH) after mild traumatic brain injury (mTBI) in patients aged ≥ 65 years. The secondary aim was to identify risk factors for intracranial lesions and evaluate the need for in-hospital observation in this age group. METHODS: This observational retrospective single-center study included all patients aged ≥ 65 years who were referred to our clinic for oral and plastic maxillofacial surgery following mTBI over a five-year period. Demographic and anamnesis data, clinical and radiological findings, and treatment were analyzed. Acute and delayed ICH and patient outcomes during hospitalization were evaluated using descriptive statistical analysis. A multivariable analysis was performed to find associations between CT findings and clinical data. RESULTS: A total of 1,062 patients (55.7% male, 44.2% female) with a mean age of 86.3 years were included in the analysis. Ground-level fall was the most frequent cause of trauma (52.3%). Fifty-nine patients (5.5%) developed an acute traumatic ICH, and 73 intracerebral lesions were radiologically observed. No association was detected between ICH rate and antithrombotic medication (p = 0.4353). The delayed ICH rate was 0.09% and the mortality rate was 0.09%. Significant risk factors for increased ICH were a Glasgow Coma Scale score of < 15, loss of consciousness, amnesia, cephalgia, somnolence, dizziness, and nausea according to multivariable analysis. CONCLUSION: Our study showed a low prevalence of acute and delayed ICH in older adults with mTBI. The ICH risk factors identified here should be considered when revising guidelines and developing a valid screening tool. Repeat CT imaging is recommended in patients with secondary neurological deterioration. In-hospital observation should be based on an assessment of frailty and comorbidities and not on CT findings alone.

Performance of a new portable near-infrared spectroscopy device for detection of traumatic intracranial hematoma.

INTRODUCTION: We report results of a newly developed portable near-infrared spectroscopy (NIRS) based point-of-care device CEREBO® to detect traumatic intracranial hematoma (TICH). MATERIALS AND METHODS: Patients with alleged history of head injury visiting emergency room were enrolled. They were examined consecutively for the presence of TICH using CEREBO® and computed tomography (CT) scans. RESULTS: A total of 158 participants and 944 lobes were scanned, and 18% of lobes were found to have TICH on imaging with computed tomography of the head. 33.9% of the lobes could not be scanned due to scalp lacerations. The mean depth of hematoma was 0.8 (SD 0.5) cm and the mean volume of the hematoma was 7.8 (11.3) cc. The overall sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of CEREBO® to classify subjects as hemorrhagic or non-hemorrhagic were 96% (CI 90 - 99%), 85% (CI 73 - 93%), 92% (CI 86 - 96%), 91% (CI 84 - 96%) and 93% (CI 82 - 98%) whereas to classify the lobes as hemorrhagic and non-hemorrhagic, the sensitivity, specificity, accuracy, PPV and NPV were 93% (CI 88 - 96%), 90% (CI 87 - 92%), 90% (CI 88 - 92%), 66% (CI 61 - 73%), and 98% (CI 97 - 99%) respectively. The sensitivity was highest at 100% (CI 92 - 100%) for the detection of extradural and subdural hematoma. The sensitivity for detecting intracranial hematoma including epidural, subdural, intracerebral and subarachnoid hematomas, of more than 2 cc was 97% (CI 93 - 99%) and the NPV was 100% (CI 99 - 100%). The sensitivity dropped for hematomas less than 2cc in volume to 84% (CI 71 - 92%) and the NPV was 99% (CI 98 - 99%). The sensitivity to detect bilateral hematomas was 94% (CI 74 - 99%). CONCLUSION: The performance of currently tested NIRS device for detection of TICH was good and can be considered for triaging a patient requiring a CT scan of the head after injury. The NIRS device can efficiently detect traumatic unilateral hematomas as well as those bilateral hematomas where the volumetric difference is greater than 2cc.

Analysis of Clinical and Laboratory Risk Factors of Post-Traumatic Intracranial Hemorrhage in Patients on Direct Oral Anticoagulants with Mild Traumatic Brain Injury: An Observational Multicenter Cohort.

BACKGROUND: Assessing the risk of intracranial hemorrhage (ICH) in patients with a mild traumatic brain injury (MTBI) who are taking direct oral anticoagulants (DOACs) is challenging. Currently, extensive use of computed tomography (CT) is routine in the emergency department (ED). OBJECTIVE: This study aims to investigate whether the clinical and laboratory characteristics presented at the ED evaluation can also estimate the risk of post-traumatic ICH in DOAC-treated patients with MTBI. METHODS: A retrospective observational study was conducted in three EDs in Italy from January 1, 2016 to March 15, 2020. All patients treated with DOACs who were evaluated for an MTBI in the ED were enrolled. The primary outcome of the study was the presence of post-traumatic ICH in the head CT performed in the ED. RESULTS: Of 930 patients on DOACs with MTBI who were enrolled, 6.8% (63 of 930) had a post-traumatic ICH and 1.5% (14 of 930) were treated with surgery or died as a result of the ICH. None of the laboratory factors were associated with an increased risk of ICH. On multivariate analysis, previous neurosurgical intervention, major trauma dynamic, post-traumatic loss of consciousness, post-traumatic amnesia, Glasgow Coma Scale score of 14, and evidence of trauma above the clavicles were associated with a higher risk of post-traumatic ICH. The net clinical benefit provided by risk factor assessment appears superior to the strategy of performing CT on all DOAC-treated patients. CONCLUSIONS: Assessment of the clinical characteristics presented at ED admission can help identify DOAC-treated patients with MTBI who are at risk of ICH.

Risk Factors Associated With Neurosurgical Intervention in Patients With Mild Traumatic Intracranial Hemorrhage.

INTRODUCTION: Community centers commonly transfer patients with traumatic intracranial hemorrhage (ICH) to level 1 and 2 trauma centers for neurosurgical evaluation regardless of the degree of injury. Determining risk factors leading to neurosurgical intervention (NSI) may reduce morbidity and mortality of traumatic ICH and the transfer of patients with lower risk of NSI. METHODS: A retrospective chart review was performed on patients admitted or transferred to a level 1 trauma center from October 2015 to September 2019 with Glassgow Coma Scale score 13-15 and traumatic ICH on initial head computerized tomography (CTH) scan. Bivariate analyses and multivariable regression were used to identify factors associated with progression to NSI. RESULTS: Of 1542 included patients, 8.2% required NSI. A greater proportion were male (69.1% versus 52.3%, P = 0.0003), on warfarin (37.7% versus 21.6%, P = 0.0023), presented with subdural hemorrhage (98.4% versus 63.3%, P < 0.0001, larger subdural hemorrhage size (median 19 mm [interquartile range {IQR}: 14-25] versus 5 mm [IQR: 3-8], P < 0.0001), and had a worsening repeat CTH (24.4% versus 13%, P < 0.0001). On physical examination, more patients had confusion (40.5% versus 31.4%, P = 0.0495) and hemiparesis (16.2% versus 2.6%, P < 0.0001). CTH findings of midline shift (80.2% versus 10.8%, P < 0.0001) and shift size (median 8.0 mm [IQR: 5.0-12.0] versus 4 mm [IQR: 3-5], P < 0.0001) were significantly associated with NSI. CONCLUSIONS: Clinical factors and patient characteristics can be used to infer a greater risk of requiring NSI. These factors could reduce unnecessary transfers and hasten the transfer of patients more likely to progress to NSI.
