Samuel S, Cortes J, Uh E, Choi HA. A systematic review of the timing of therapeutic anticoagulation in adult patients with acute traumatic brain injury: narrative synthesis of observational studies. Neurosurg Rev 2024; 47:538. [PMID: 39231815 DOI: 10.1007/s10143-024-02717-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2024] [Revised: 08/09/2024] [Accepted: 08/18/2024] [Indexed: 09/06/2024]
Abstract
Traumatic brain injury (TBI) presents complex management scenarios, particularly in patients requiring anticoagulation for concurrent conditions such as venous thromboembolism (VTE) or atrial fibrillation (AF). A systematic search of PubMed/MEDLINE, Embase, and the Cochrane Library databases was conducted to identify relevant studies. Inclusion criteria encompassed studies assessing the effects of anticoagulation therapy on outcomes such as re-hemorrhage, hematoma expansion, thrombotic events, and hemorrhagic events in TBI patients with subdural hematomas (SDH). This systematic review critically addresses two key questions: the optimal timing for initiating anticoagulation therapy and the differential impact of this timing based on the type of intracranial bleed, with a specific focus on subdural hematomas (SDH) compared to other types. Initially screening 508 articles, 7 studies met inclusion criteria, which varied in design and quality, precluding meta-analysis. The review highlights a significant knowledge gap, underscoring the lack of consensus on when to initiate anticoagulation therapy in TBI patients, exacerbated by the need for anticoagulation in the presence of VTE or AF. Early anticoagulation, particularly in patients with SDH, may elevate the risk of re-hemorrhage, posing a clinical dilemma. Evidence on whether the type of intracranial hemorrhage influences outcomes with early anticoagulation remains inconclusive, indicating a need for further research to tailor management strategies effectively. This review underscores the scarcity of high-quality evidence regarding anticoagulation therapy in TBI patients with concurrent conditions, emphasizing the necessity for well-designed prospective studies to elucidate optimal management strategies for this complex patient population.

Abstract
BACKGROUND Expanding the number of biomarkers is imperative for studying the etiology and improving venous thromboembolism prediction. In this study, we aimed to identify promising biomarkers or targeted therapies to improve the detection accuracy of early-stage deep vein thrombosis (DVT) or reduce complications. METHODS Quantibody Human Cytokine Antibody Array 440 (QAH-CAA-440) was used to screen novel serum-based biomarkers for DVT/non-lower extremity DVT (NDVT). Differentially expressed proteins in DVT were analyzed using bioinformatics methods and validated using a customized array. Diagnostic accuracy was calculated using receiver operating characteristics, and machine learning was applied to establish a biomarker model for evaluating the identified targets. Twelve targets were selected for validation. RESULTS Cytokine profiling was conducted using a QAH-CAA-440 (RayBiotech, USA) quantimeter array. Cross-tabulation analysis with Venn diagrams identified common differential factors, leading to the selection of 12 cytokines for validation based on their clinical significance. These 12 biomarkers were consistent with the results of previous array analysis: FGF-6 (AUC = 0.956), Galectin-3 (AUC = 0.942), EDA-A2 (AUC = 0.933), CHI3L1 (AUC = 0.911), IL-1 F9 (AUC = 0.898), Dkk-4 (AUC = 0.88), IG-H3 (AUC = 0.876), IGFBP (AUC = 0.858), Gas-1 (AUC = 0.858), Layilin (AUC = 0.849), ULBP-2 (AUC = 0.813)and FGF-9 (AUC = 0.773). These cytokines are expected to serve as biomarkers, targets, or therapeutic targets to differentiate DVT from NDVT. CONCLUSIONS EDA-A2, FGF-6, Dkk-4, IL-1 F9, Galentin-3, Layilin, Big-h3, CHI3L1, ULBP-2, Gas-1, IGFBP-5, and FGF-9 are promising targets for DVT diagnosis and treatment.

Abstract
The best management of patients who suffer from traumatic brain injury (TBI) while on oral anticoagulants is one of the most disputed problems of emergency services. Indeed, guidelines, clinical decision rules, and observational studies addressing this topic are scarce and conflicting. Moreover, relevant issues such as the specific treatment (and even definition) of mild TBI, rate of delayed intracranial injury, indications for neurosurgery, and anticoagulant modulation are largely empiric. We reviewed the most recent evidence on these topics and explored other clinically relevant aspects, such as the promising role of dosing brain biomarkers, the strategies to assess the extent of anticoagulation, and the indications of reversals and tranexamic acid administration, in cases of mild TBI or as a bridge to neurosurgery. The appropriate timing of anticoagulant resumption was also discussed. Finally, we obtained an insight into the economic burden of TBI in patients on oral anticoagulants, and future directions on the management of this subpopulation of TBI patients were proposed. In this article, at the end of each section, a "take home message" is stated.

Abstract
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.

Abstract
BACKGROUND AND PURPOSE Non-O blood types are known to be associated with thromboembolic complications (TECs) in population-based studies. TECs are known drivers of morbidity and mortality in intracerebral hemorrhage (ICH) patients, yet the relationships of blood type on TECs in this patient population are unknown. We sought to explore the relationships between ABO blood type and TECs in ICH patients. METHODS Consecutive adult ICH patients enrolled into a prospective observational cohort study with available ABO blood type data were analyzed. Patients with cancer history, prior thromboembolism, and baseline laboratory evidence of coagulopathy were excluded. The primary exposure variable was blood type (non-O versus O). The primary outcome was composite TEC, defined as pulmonary embolism, deep venous thrombosis, ischemic stroke or myocardial infarction, during the hospital stay. Relationships between blood type, TECs and clinical outcomes were separately assessed using logistic regression models after adjusting for sex, ethnicity and ICH score. RESULTS Of 301 ICH patients included for analysis, 44% were non-O blood type. Non-O blood type was associated with higher admission GCS and lower ICH score on baseline comparisons. We identified TECs in 11.6% of our overall patient cohort. . Although TECs were identified in 9.9% of non-O blood type patients compared to 13.0% in O blood type patients, we did not identify a significant relationship of non-O blood type with TECs (adjusted OR=0.776, 95%CI: 0.348-1.733, p=0.537). The prevalence of specific TECs were also comparable in unadjusted and adjusted analyses between the two cohorts. In additional analyses, we identified that TECs were associated with poor 90-day mRS (adjusted OR=3.452, 95% CI: 1.001-11.903, p=0.050). We did not identify relationships between ABO blood type and poor 90-day mRS (adjusted OR=0.994, 95% CI:0.465-2.128, p=0.988). CONCLUSIONS We identified that TECs were associated with worse ICH outcomes. However, we did not identify relationships in ABO blood type and TECs. Further work is required to assess best diagnostic and prophylactic and treatment strategies for TECs to improve ICH outcomes.

Abstract
The use of anticoagulants has become more frequent due to the progressive aging population and increased thromboembolic events. Consequently, the proportion of anticoagulant-associated intracerebral hemorrhage (AAICH) in stroke patients is gradually increasing. Compared with intracerebral hemorrhage (ICH) patients without coagulopathy, patients with AAICH may have larger hematomas, worse prognoses, and higher mortality. Given the need for anticoagulant reversal and resumption, the management of AAICH differs from that of conventional medical or surgical treatments for ICH, and it is more specific. Understanding the pharmacology of anticoagulants and identifying agents that can reverse their effects in the early stages are crucial for treating life-threatening AAICH. When patients transition beyond the acute phase and their vital signs stabilize, it is important to consider resuming anticoagulants at the right time to prevent the occurrence of further thromboembolism. However, the timing and strategy for reversing and resuming anticoagulants are still in a dilemma. Herein, we summarize the important clinical studies, reviews, and related guidelines published in the past few years that focus on the reversal and resumption of anticoagulants in AAICH patients to help implement decisive diagnosis and treatment strategies in the clinical setting.

Abstract
BACKGROUND There are limited data on anticoagulant management of acute venous thromboembolism (VTE) after spontaneous intracranial hemorrhage (ICH). METHODS We reviewed retrospectively all cases diagnosed with VTE during hospitalization for spontaneous ICH at our center during 15 years. Anticoagulation management outcomes were (1) timing after ICH of anticoagulant initiation for VTE treatment, (2) use of immediate therapeutic dosing or stepwise dose escalation, and (3) the proportion achieving therapeutic dose. Primary clinical effectiveness outcome was recurrent VTE. Primary safety outcome was expanding ICH. RESULTS We analyzed 103 cases with VTE after 11 days (median; interquartile range [IQR]: 7-22) from the diagnosis of ICH. Forty patients (39%) achieved therapeutic anticoagulation 21.5 days (median; IQR: 14-34 days) from the ICH. Of those, 14 (35%; 14% of total) received immediately therapeutic dose and 26 (65%; 25% of total) had stepwise escalation. Anticoagulation was more aggressive in patients with VTE >14 days after admission versus those with earlier VTE diagnosis. Twenty-two patients (21%) experienced recurrent/progressive VTE-less frequently among patients with treatment escalation within 7 days or with no escalation than with escalation >7 days from the VTE. There were 19 deaths 6 days (median; IQR: 3.5-15) after the index VTE, with significantly higher in-hospital mortality rate among patients without escalation in anticoagulation. CONCLUSION Prompt therapeutic anticoagulation for acute VTE seems safe when occurring more than 14 days after spontaneous ICH. For VTE occurring earlier, it might also be safe with therapeutic anticoagulation, but stepwise dose escalation to therapeutic within a 7-day period might be preferable.

Abstract
Traumatic brain injury (TBI) is a major global health concern. Due to the increase in TBI incidence and the aging population, an increasing number of patients with TBI are taking antithrombotic agents for their underlying disease. When TBI occurs in patients with these diseases, there is a conflict between the disease, which requires an antithrombotic effect, and the neurosurgeon, who must minimize intracranial hemorrhage. Nevertheless, there are no clear guidelines for the reversal or resumption of antithrombotic agents when TBI occurs in patients taking antithrombotic agents. In this review article, we intend to classify antithrombotic agents and provide information on them. We also share previous studies on the reversal and resumption of antithrombotic agents in patients with TBI to help neurosurgeons in this dilemma.

Abstract
Background Anticoagulants prevent thrombosis in patients with atrial fibrillation (AF) and venous thromboembolism but increase the risk of hemorrhagic complications. If severe bleeding occurs with anticoagulant use, discontinuation and rapid reversal are essential. However, the optimal timing for resuming anticoagulants after using reversal agents remains unclear. Here, we report early cerebral infarction following the use of andexanet alfa (AA), a specific reversal agent for factor Xa inhibitors, in a patient with traumatic acute subdural hematoma (ASDH). The possible causes of thromboembolic complication and the optimal timing for anticoagulant resumption are discussed. Case Description An 84-year-old woman receiving rivaroxaban for AF presented with impaired consciousness after a head injury. Computed tomography (CT) revealed right ASDH. The patient was administered AA and underwent craniotomy. Although the hematoma was entirely removed, she developed multiple cerebral infarctions 10 h after the surgery. These infarctions were considered cardiogenic cerebral embolisms and rivaroxaban was therefore resumed on the same day. This case indicates the possibility of early cerebral infarction after using a specific reversal agent for factor Xa inhibitors. Conclusion Most studies suggest that the safest time for resuming anticoagulants after using reversal agents is between 7 and 12 days. The present case showed that embolic complications may develop much earlier than expected. Early readministration of anticoagulant may allow for adequate prevention of the acute thrombotic syndromes.

Relationships between blood type, TECs and clinical outcomes were separately assessed using logistic regression models after adjusting for sex, ethnicity and ICH score. Results Of 301 ICH patients included for analysis, 44% were non-O blood type. Non-O blood type was associated with higher admission GCS and lower ICH score on baseline comparisons. We identified TECs in 11.6% of our overall patient cohort. Although TECs were identified in 9.9% of non-O blood type patients compared to 13.0% in O blood type patients, we did not identify a significant relationship of non-O blood type with TECs (adjusted OR = 0.776, 95%CI: 0.348-1.733, p = 0.537). The prevalence of specific TECs were also comparable in unadjusted and adjusted analyses between the two cohorts. In additional analyses, we identified that TECs were associated with poor 90-day mRS (adjusted OR = 3.452, 95% CI: 1.001-11.903, p = 0.050). We did not identify relationships between ABO blood type and poor 90-day mRS (adjusted OR = 0.994, 95% CI:0.465-2.128, p = 0.988). Conclusions We identified that TECs were associated with worse ICH outcomes. However, we did not identify relationships in ABO blood type and TECs. Further work is required to assess best diagnostic and prophylactic and treatment strategies for TECs to improve ICH outcomes.

Abstract
BACKGROUND Anticoagulation is used to prevent thromboembolic events. It is a common practice to hold anticoagulation in the first few days following a traumatic brain injury (TBI) with intracranial hemorrhage. However, traumatic subdural hematomas (SDH) are prone to re-hemorrhage long after the trauma. Data are scarce in the literature on the best timing to resume anticoagulation following a TBI. METHODS Review of 95 consecutive patients admitted to a level 1 trauma center with a diagnosis of traumatic SDH and requiring anticoagulation. The reasons for anticoagulation, the amount of time without anticoagulation, CT characteristics, and the incidence of thromboembolic events or SDH re-hemorrhage were collected. RESULTS 41.3% used anticoagulation for coronary artery disease and peripheral vascular disease, 24% for atrial fibrillation, 12% for cardiac valve replacement, and 12% for venous thromboembolic events. Anticoagulation was held a median of 67 days. For most patients (82.1%), anticoagulation was re-introduced once the SDH had completely resolved. For 17.9%, anticoagulation was restarted while the SDH had not completely resolved. One (1.1%) patient suffered from an atrial clot while anticoagulation was held. For those with residual SDH, 41.2% suffered from a SDH re-hemorrhage and 17.6% required surgery. The risk of re-hemorrhage climbed to 62.5% if the SDH remnant was large. CONCLUSION Anticoagulation while there is a residual SDH was associated with a significant risk of re-hemorrhage. This risk should be weighed against the risk of holding anticoagulation.

Abstract
Currently, there is no consensus guideline for initiating anticoagulation in patients with a traumatic or vascular brain injury. Initiating anticoagulation for management of venous thromboembolism (VTE) can vary significantly from 72 hours to 30 weeks due to the risk of hemorrhagic complications. The purpose of this study is to compare clinical outcomes using modified Rankin Score (mRS) in a patient population with early (≤ 3 days) versus late (> 3 days) initiation of therapeutic anticoagulation from the time VTE was diagnosed. This retrospective study included patients with a traumatic or vascular brain injury who developed either deep vein thrombosis (DVT) or pulmonary embolism (PE). Use of anticoagulation prior to admission, diagnosis with VTE on admission, or patients with a non-brain injury were exclusion criteria. Secondary outcomes measured were all-cause mortality, length of stay, and reasons for early interruption of anticoagulation. Therapeutic anticoagulation was started early in 76 (74%) patients compared to late initiation in 27 (26%) patients. Baseline characteristics were similar between the two groups. The mRS score 0-3 versus 4-6 was similar in patients who received early anticoagulation versus those who received it later. However, there was a trend favoring better outcomes in the early group [mRS 4-6; 78% vs. 93%; p = 0.085] and in subgroup analysis of patients with VTE diagnosed 4-7 days [mRS 4-6; 26% vs. 56%; p = 0.006] compared to the late group. In univariate and multivariable logistic regression, only age was associated with a significant worse outcome (median, IQR) 36 years (24-50) vs. 58 years (44-65) OR 1.07 (1.03-1.12); p < 0.001. In this study, early initiation of anticoagulation did not worsen clinical outcomes.

Abstract
PURPOSE OF REVIEW When to resume or initiate anticoagulation therapy following traumatic brain injury (TBI) is controversial. This summary describes the latest evidence to guide best practice. RECENT FINDINGS Following trauma, prophylactic, and therapeutic anticoagulation (TAC) have been widely encouraged to prevent major comorbidities such as pulmonary embolism and deep venous thrombosis. Increased rebleeding risk and potentially catastrophic outcome from initiation of anticoagulation treatment in TBI are mainly influenced by institutional guidelines or physician preference in the absence of level I or II recommendations. In recent years, there has been an increasing number of TBI in the elderly population on anticoagulation for other medical conditions; this complicates the decision and timing to restart anticoagulation after the injury. SUMMARY Strategies and timing to start prophylactic and TAC differ significantly between institutions and physicians. Each TBI patient should be evaluated on a case-by-case basis on when to start anticoagulation. More investigation is required to guide best practice.

Abstract
OBJECTIVE To assess the risk of hematoma expansion in patients with acute intracranial hemorrhage (ICH) requiring therapeutic anticoagulation for the treatment of venous thromboembolism. METHODS We retrospectively reviewed all patients at our institution between 2014 and 2019 who were therapeutically anticoagulated for venous thromboembolism within 4 weeks after ICH. We included subtypes of traumatic ICH and spontaneous intraparenchymal hemorrhage. Our main outcome was the incidence of hematoma expansion within 14 days from initiating therapeutic anticoagulation. Hematoma expansion was defined as (1) radiographically proven expansion leading to cessation of therapeutic anticoagulation or (2) death due to hematoma expansion. Secondary outcomes included mortality due to hematoma expansion and characteristics associated with hematoma expansion. RESULTS Fifty patients met inclusion criteria (mean age: 54 years, 80% male, 76% Caucasian); 24% had undergone a neurosurgical procedure prior to therapeutic anticoagulation. Median time from ICH to therapeutic anticoagulation initiation was 9.5 days (IQR 4-17), 40% received therapeutic anticoagulation in <7 days after ICH. Six patients (12%) developed hematoma expansion, of whom two (4%) died. While not statistically significant, patients with hematoma expansion tended to be older (57.8 vs. 53.5 years), were anticoagulated sooner (4 vs. 10 days), presented with lower GCS (50% vs. 39% with GCS <8), higher hematoma volume (50% vs. 42% >30 cc), and higher SDH diameter (16 mm vs. 8.35 mm). There was a trend towards greater risk of hematoma expansion for patients undergoing endoscopic ICH evacuation (16% vs. 2%, p = 0.09); patients with hematoma expansion were more likely to present with hydrocephalus (67% vs. 16%, p = 0.02). CONCLUSIONS Our study is among the first to explore characteristics associated with hematoma expansion in patients undergoing therapeutic anticoagulation after acute ICH. Larger studies in different ICH subtypes are needed to identify determinants of hematoma expansion in this high-acuity population.

Abstract
BACKGROUND Deep vein thrombosis (DVT) often occurs following major orthopedic surgery. In this study, we investigated specific exosomal proteins as potential diagnostic biomarkers of DVT. METHODS Proteomic analysis of exosomes from four DVT patients and healthy controls (n=4) was performed by mass spectrometry. The model animals were evaluated at 1 inferior vena cava ligation [(IVCL)-1D], 3 (IVCL-3D), and 7 (IVCL-7D) days after IVCL. Endothelial cells in the thrombus segment were examined using terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays and hematoxylin and eosin (HE) staining. Myeloperoxidase (MPO) expression in the damaged vessel was detected by immunofluorescence staining. Exosomes were co-cultured with human umbilical vein endothelial cells (HUVECs) and cell proliferation was estimated using Cell Counting Kit-8 (CCK-8) assays. RESULTS A total of 78 differentially expressed proteins (DEPs; 38 downregulated and 40 upregulated) were identified in the DVT group. In the rat DVT model, endothelial cells were damaged continuously after thrombosis, with the most serious injury in the IVCL-3D group, after which signs of endothelial repair were apparent. The IVCL-1D group showed the highest levels of vascular endothelial cell apoptosis and MPO increased sharply in the IVCL-1D and IVCL-3D groups, but had almost disappeared in the IVCL-7D group. In co-culture, plasma exosomes isolated from DVT model rats were efficiently absorbed by HUVECs, with markedly lower HUVECs growth and higher levels of apoptosis in the IVCL-1D and IVCL-3D groups compared with the control group. CONCLUSIONS Our findings suggest that exosomes may be involved in endothelial cell injury during DVT. The exosomal protein MPO is a potential biomarker of early stage DVT.

Abstract
Anticoagulants prevent thrombosis and death in patients with atrial fibrillation and venous thromboembolism (VTE) but also increase bleeding risk. The benefit/risk ratio favors anticoagulation in most of these patients. However, some will have a bleeding complication, such as the common trip-and-fall brain injury in elderly patients that results in traumatic intracranial hemorrhage. Clinicians must then make the difficult decision about when to restart the anticoagulant. Restarting too early risks making the bleeding worse. Restarting too late risks thrombotic events such as ischemic stroke and VTE, the indications for anticoagulation in the first place. There are more data on restarting patients with spontaneous intracranial hemorrhage, which is very different than traumatic intracranial hemorrhage. Spontaneous intracranial hemorrhage increases the risk of rebleeding because intrinsic vascular changes are widespread and irreversible. In contrast, traumatic cases are caused by a blow to the head, usually an isolated event portending less future risk. Clinicians generally agree that anticoagulation should be restarted but disagree about when. This uncertainty leads to long restart delays causing a large, potentially preventable burden of strokes and VTE, which has been unaddressed because of the absence of high quality evidence. Restart Traumatic Intracranial Hemorrhage (the "r" distinguished intracranial from intracerebral) (TICrH) is a prospective randomized open label blinded end-point response-adaptive clinical trial that will evaluate the impact of delays to restarting direct oral anticoagulation (1, 2, or 4 weeks) on the composite of thrombotic events and bleeding in patients presenting after traumatic intracranial hemorrhage.

Abstract
Anticoagulant-associated traumatic intracranial hemorrhage (tICrH) is a devastating injury with high morbidity and mortality. For survivors, treating clinicians face the dilemma of restarting oral anticoagulation with scarce evidence to guide them. Thromboembolic risk is high from the bleeding event, patients’ high baseline risks, that is, the pre-existing indication for anticoagulation, and the risk of immobility after the bleeding episode. This must be balanced with potentially devastating hematoma expansion or new hemorrhagic lesions. Retrospective evidence and expert opinion support restarting oral anticoagulants in most patients with tICrH, but timing is uncertain. Researchers have failed to make clear distinctions between tICrH and spontaneous intracranial hemorrhage (sICrH), which have differing natural histories. While both appear to benefit from restarting, sICrH has a higher rebleeding risk and similar or lower thrombotic risk. Clinical equipoise on restarting is also divergent. In sICrH, equipoise is centered on whether to restart. In tICrH, it is centered on when. Several prospective randomized clinical trials are ongoing or about to start to examine the risk–benefit of restarting. Most of them are restricted to patients with sICrH, with antiplatelet control groups. Most are also restricted to direct oral anticoagulants (DOACs), as they are associated with a lower overall risk of ICrH. There is some overlap with tICrH via subdural hematoma, and one trial is specific to restart timing with DOACs in only traumatic cases. This is a narrative review of the current evidence for restarting anticoagulation and restart timing after tICrH along with a summary of the ongoing and planned clinical trials.

Abstract
BACKGROUND Trauma care providers often face a dilemma regarding anticoagulation therapy initiation in patients with traumatic brain injury owing to the associated risks of traumatic brain injury progression. The aims of this study were the following: (1) to describe the current practice of anticoagulation therapy in traumatic brain injury patients and their outcomes and (2) to identify factors associated with the progression of traumatic brain injury after anticoagulation therapy. METHODS In this multicenter prospective observational study, we included computed tomography-proven traumatic brain injury patients who received anticoagulation therapy within 30 days of hospital admission. Our primary outcome was the incidence of clinically significant progression of traumatic brain injury after anticoagulation therapy initiation. RESULTS A total of 168 patients were enrolled more than 22 months. Atrial fibrillation and venous thromboembolism were the most common pre-injury and postinjury anticoagulation therapy indications, respectively. Overall, 16 patients (9.6%) experienced clinically significant traumatic brain injury progression after anticoagulation therapy, out of which 9 (5.4%) patients subsequently required neurosurgical interventions. Between patients with clinical progression of traumatic brain injury and patients who showed no such progression, there were no significant differences in the baseline demographics and severity of traumatic brain injury. However, anticoagulation therapy was initiated significantly earlier in patients of the deterioration group than those of the no-deterioration group (4.5 days vs 11 days, P = .015). In a multiple logistic regression model, patients who received anticoagulation therapy later after injury had significantly lower risk of clinically significant traumatic brain injury progression (odds ratio: 0.915 for each day, 95% confidence interval: 0.841-0.995, P = .037). CONCLUSION Our results suggest that early anticoagulation therapy is associated with higher risk of traumatic brain injury progression, thus a balance between bleeding and thromboembolic risks should be carefully evaluated in each case before initiating anticoagulation therapy.

Abstract
BACKGROUND Patients with traumatic intracranial hemorrhage (ICH) and concomitant pulmonary embolus (PE) have competing care needs and demand a careful balance of anticoagulation (AC) versus potential worsening of their ICH. The goal of this study is to determine the safety of therapeutic AC for PE in patients with ICH. METHODS This is a retrospective single-center study of patients older than 16 years with concomitant ICH and PE occurring between June 2013 and December 2017. Early AC was defined as within 7 days of injury or less; late was defined as after 7 days. Primary outcomes included death, interventions for worsening ICH following AC, and pulmonary complications. Multivariate logistic regression was used to evaluate for clinical and demographic factors associated with worsening traumatic brain injury (TBI), and recursive partitioning was used to differentiate risk in groups. RESULTS Fifty patients met criteria. Four did not receive any AC and were excluded. Nineteen (41.3%) received AC early (median, 4.1; interquartile range, 3.1-6) and 27 (58.7%) received AC late (median, 14; interquartile range, 9.7-19.5). There were four deaths in the early group, and none in the late cohort (21.1% vs. 0%, p = 0.01). Two deaths were due to PE and the others were from multi-system organ failure or unrecoverable underlying TBI. Three patients in the early group, and two in the late, had increased ICH on computed tomography (17.6% vs. 7.4%, p = 0.3). None required intervention. CONCLUSION This retrospective study failed to find instances of clinically significant progression of TBI in 46 patients with computed tomography-proven ICH after undergoing AC for PE. Therapeutic AC is not associated with worse outcomes in patients with TBI, even if initiated early. However, two patients died from PE despite AC, underlining the severity of the disease. Intracranial hemorrhage should not preclude AC treatment for PE, even early after injury. LEVEL OF EVIDENCE Care management, Level IV.

Abstract
OBJECTIVE Anticoagulant therapy (ACT) after traumatic intracranial hemorrhage may lead to progression of hemorrhage, but in the presence of thromboembolic events, the clinician must decide if the benefits outweigh the risks. Currently, no data exist to guide therapy in the acute setting. METHODS We retrospectively identified all patients admitted to our institution with traumatic intracranial hemorrhage that received intravenous heparin, full-dose enoxaparin, or warfarin during their initial hospitalization over a 3-year period. We reviewed their demographics, hospital course, clinical indication and timing for initiation of ACT, and complications. RESULTS A total of 112 patients were identified. The median age and Glasgow Coma Scale score of these patients was 50.5 years and 9.5, respectively. Twenty-two patients required neurosurgical procedures for their presenting injury, including intracranial pressure monitors and/or open surgeries. Fifty-four patients had deep vein thrombosis or pulmonary embolism prior to initiation, and the remaining 20 patients had preexisting conditions or other indications for initiating ACT. The median time from injury to starting ACT was 8 days. Immediate complications occurred in 6 patients; however, none of these patients required a neurosurgical intervention. Delayed complications included progression of acute to chronic subdural hematoma that required intervention in 2 patients. One patient died from delayed hemorrhage. CONCLUSIONS For this patient population, the risk of immediate and delayed intracranial hemorrhages from initiating ACT therapy in intracranial injury must be weighed against the morbidity of delaying treatment. Although further studies are needed, our review provides the first rates of complications for this patient population.

Abstract
OBJECTIVE Blunt cerebrovascular injuries (BCVIs) following trauma carry risk for morbidity and mortality. Since patients with BCVI are often asymptomatic at presentation and neurological sequelae often occur within 72 hours, timely diagnosis is essential. Multidetector CT angiography (CTA) has been shown to be a noninvasive, cost-effective, reliable means of screening; however, the false-positive rate of CTA in diagnosing patients with BCVI represents a key drawback. Therefore, the authors assessed the role of DSA in the screening of BCVI when utilizing CTA as the initial screening modality. METHODS The authors performed a retrospective analysis of patients who experienced BCVI between 2013 and 2015 at 2 Level I trauma centers. All patients underwent CTA screening for BCVI according to the updated Denver Screening Criteria. Patients who were diagnosed with BCVI on CTA underwent confirmatory digital subtraction angiography (DSA). Patient demographics, screening indication, BCVI grade on CTA and DSA, and laboratory values were collected. Comparison of false-positive rates stratified by BCVI grade on CTA was performed using the chi-square test. RESULTS A total of 140 patients (64% males, mean age 50 years) with 156 cerebrovascular blunt injuries to the carotid and/or vertebral arteries were identified. After comparison with DSA findings, CTA findings were incorrect in 61.5% of vessels studied, and the overall CTA false-positive rates were 47.4% of vessels studied and 47.9% of patients screened. The positive predictive value (PPV) for CTA was higher among worse BCVI subtypes on initial imaging (PPV 76% and 97%, for BCVI Grades II and IV, respectively) compared with Grade I injuries (PPV 30%, p < 0.001). CONCLUSIONS In the current series, multidetector CTA as a screening test for blunt cerebrovascular injury had a high-false positive rate, especially in patients with Grade I BCVI. Given a false-positive rate of 47.9% with an estimated average of 132 patients per year screening positive for BCVI with CTA, approximately 63 patients per year would potentially be treated unnecessarily with antithrombotic therapy at a busy United States Level I trauma center. The authors' data support the use of DSA after positive findings on CTA in patients with suspected BCVI. DSA as an adjunctive test in patients with positive CTA findings allows for increased diagnostic accuracy in correctly diagnosing BCVI while minimizing risk from unnecessary antithrombotic therapy in polytrauma patients.

Abstract
Patients with traumatic intracranial hemorrhage (ICH) with a clinical indication for antithrombotic medication present a clinical dilemma, burdened by the task of weighing the risks of hemorrhage expansion against the risk of thrombosis. We sought to determine the effect of subdural hemorrhage on the risk of hemorrhage expansion after administration of antithrombotic medication. Medical records of 1626 trauma patients admitted with traumatic ICH between March 1, 2008, and March 31, 2013, to a Level I trauma center were retrospectively reviewed. The pharmacy database was queried to determine which patients were administered anticoagulant or antiplatelet medication during their hospitalization, leaving a sample of 97 patients that met inclusion criteria. Patients presenting with subdural hemorrhage were compared with patients without subdural hemorrhage. Demographic data, clinically significant expansion of hematoma, postinjury day of initiation, and mortality were analyzed. A total of 97 patients met inclusion criteria with 55 patients in the subdural hemorrhage group and 42 in the other ICH group. There were no significant differences in age, gender, injury severity score, admission Glasgow coma score, or mean hospital day of antithrombotic administration between the groups. Patients with subdural hemorrhage had a significantly higher rate of ICH expansion (9.1 vs 0%, P = 0.045). There was no difference in overall hospital mortality between the two groups. Incidence of ICH expansion was higher in patients with subdural hemorrhage. It may be prudent to use special caution when administering antiplatelet or anticoagulant medication in this group of patients after injury.

Abstract
Outpatient anticoagulation in the geriatric trauma patient is a challenging clinical problem. The aim of this study is to determine clinical outcomes associated with class of preinjury anticoagulants (PA) used by this population. This is a multicenter retrospective cohort study among four Level II trauma centers. A total of 1642 patients were evaluated; 684 patients were on anticoagulation and 958 patients were not. Patients on PA were compared with those who were not. Drug classes were divided into thromboxane A2 inhibitors, vitamin K factor-dependent inhibitors, antithrombin III activation, platelet P2Y12 inhibitors, and thrombin inhibitors. Multivariate regression was used to adjust for age, gender, race, mechanism of injury, and Injury Severity Score. No single or combination of anticoagulation agents had a significant association with mortality; however, there were positive trends toward increased mortality were noted for all antiplatelet groups involving thromboxane A2 inhibitors and platelet P2Y12 inhibitors classes. The likelihood of complications was significantly higher with platelet P2Y12 inhibitors adjusted odds ratio (aOR) 2.39 [95% confidence interval (CI) 1.32, 4.3]. The likelihood of blood transfusion was increased with vitamin K inhibitors aOR 2.89 (95% CI 1.3, 6.5), P2Y12 inhibitors aOR 2.76 (95% CI 1.12, 6.76), and combined thromboxane A2 and P2Y12 inhibitors aOR 2.89 (95% CI 1.13, 7.46). P2Y12 inhibitors were also more likely associated with traumatic brain injury aOR 2.16 (95% CI 1.01, 4.6). All classes of PA were associated with solid organ injury. There were no significant differences in the use of antiplatelet agents between patients with major indications for PA and those without major indications. Geriatric trauma patients on outpatient anticoagulants have a higher likelihood of developing complications, packed red blood cell transfusions, traumatic brain injury, and solid organ injury. Attention should be paid to patients on platelet P2Y12 inhibitors, vitamin K inhibitors, and thromboxane A2 inhibitor agents combined with platelet P2Y12 inhibitors. Opportunities exist to address the use of antiplatelet agents among patients without major indications to improve patient outcomes.

Abstract
Patients with active bleeding complications who concomitantly develop overt pulmonary embolism (PE) present distinct therapeutic dilemmas, since they are perceived to be at substantial risk for the progression of the embolism in the absence of treatment and for aggravation of the hemorrhagic lesions if treated with anticoagulants. A 76-year-old patient with nephrotic syndrome, which is associated with an increased risk of thromboembolism, concurrently developed acute PE and intracranial bleeding because of traumatic brain injury. In this case, we prioritized the treatment for PE with the intravenous unfractionated heparin followed by warfarinization. Despite the transient hemorrhagic progression of the brain contusion after the institution of anticoagulation, our patient recovered favorably from the disease without any signs of neurological compromise. Several conundrums regarding anticoagulation that emerged in this case are also discussed.

Abstract
BACKGROUND Therapeutic anticoagulation (TAC) is often required in trauma patients for various indications. However, it remains unknown whether TAC can be safely initiated in the postinjury period for patients with traumatic brain injury (TBI). The purpose of this study was to evaluate the safety of TAC in TBI patients. MATERIALS AND METHODS We conducted a 7-y retrospective study. All TBI patients who received TAC within 60 d postinjury were included. In addition to patient and injury characteristics, detailed information regarding TAC was collected. The primary outcome was the incidence of neurologic deterioration or progression of hemorrhagic TBI on repeat head computed tomography (CT) after initiation of TAC. Univariate and multivariate analyses were used to identify factors associated with progression of hemorrhagic TBI after TAC. RESULTS A total of 3355 TBI patients were identified. Of those, 72 patients (2.1%) received TAC. Median age, 59; 76.4% male; median Injury Severity Score, 19; median admission Glasgow Coma Scale, 14; and median Rotterdam score on the initial head CT, 3. Although atrial fibrillation was the most common preinjury indication for TAC, venous thromboembolism was the most common postinjury indication. The median postinjury time of initiation of TAC was 9 d. Intravenous heparin infusion was the most commonly used agent for TAC (70.8%). None of our study patients developed any signs of neurologic deterioration due to TAC. Progression of hemorrhagic TBI on repeat head CT was observed in six patients. In a multiple logistic regression model, aged ≥65 y was significantly associated with progression of hemorrhagic TBI after TAC (odds ratio, 15.2; 95% confidence interval, 1.1-212.7; P = 0.04). CONCLUSIONS This study shows preliminary data regarding TAC initiated in patients with TBI. Further prospective study is warranted to determine the risks and benefits of TAC in this specific group of patients.

Abstract
We report on a case of catheter-related thrombosis after 7‑day catheter placement during intravascular temperature management (IVTM), in spite of the use of prophylactic anticoagulants. There were no clinical sequelae. According to the literature, occult thrombosis during ITVM could be more frequent than previously reported and dedicated monitoring for potential thrombosis may be indicated. However, a study comparing IVTM with surface cooling found no differences in clinical outcome. Therefore, n either of the methods can be recommended over the other. Further studies should evaluate the rate of occult thrombosis during the use of both cooling methods.
