[PMID: 38677659 DOI: 10.1016/j.jvs.2024.04.053] [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: 03/06/2024] [Revised: 04/12/2024] [Accepted: 04/22/2024] [Indexed: 04/29/2024]
Abstract
OBJECTIVE There is a lack of data on the role of characteristics of injured vessels on the outcomes of patients with blunt cerebrovascular injuries (BCVIs). The aim of this study was to assess the effect of the number (single vs multiple) of injured vessels on outcomes. METHODS This is a retrospective study at two American College of Surgeons Level I trauma centers (2017-2021). Adult (>16 years) trauma patients with BCVIs are included. Injuries were graded by the Denver Scale based on the initial computed tomography angiography (CTA). Early repeat CTA was performed 7 to 10 days after diagnosis. Patients were stratified by the number (single vs multiple) of the involved vessels. Outcomes included progression of BCVIs on repeat CTA, stroke, and in-hospital mortality attributable to BCVIs. Multivariable regression analyses were performed to identify the association between the number of injured vessels and outcomes. RESULTS A total of 491 patients with 591 injured vessels (285 carotid and 306 vertebral arteries) were identified. Sixty percent were male, the mean age was 44 years, and the median Injury Severity Score was 18 (interquartile range, 11-25). Overall, 18% had multiple-vessel injuries, 16% had bilateral vessel injuries, and 3% had multiple injuries on the same side. The overall rates of progression to higher-grade injuries, stroke, and mortality were 23%, 7.7%, and 8.8%, respectively. On uni- and multivariable analyses, multiple BCVIs were associated with progression to higher-grade injuries on repeat imaging, stroke, and mortality compared with single-vessel injuries. CONCLUSIONS BCVIs with multiple injured vessels are more likely to progress to higher grades on repeat CTA, with multiple injuries independently associated with worse clinical outcomes, compared with those with single injuries. These findings highlight the importance of incorporating the number of injured vessels in clinical decision-making and in defining protocols for repeat imaging.

Abstract
To assess the effectiveness and safety of antiplatelet therapy compared with anticoagulation therapy in preventing stroke occurrence following blunt carotid injuries. A comprehensive search was conducted on Medline, Central, and Embase using mesh criteria, yielding 1236 articles. Additionally, 3 studies met the inclusion criteria. Two review authors independently extracted data from randomized controlled trials, controlled clinical trials, and nonrandomized studies comparing anticoagulant and antiplatelet therapies for carotid blunt trauma. Primary outcomes included stroke, transient ischemic attack, and mortality, with secondary outcomes encompassing major extracranial bleeding events. Drug dosage, treatment duration, and follow-up data were extracted and analyzed. Only 1 randomized trial was identified, and 3 studies met all exclusion and inclusion criteria (comprising 796 patients). The odds of stroke [1.13, 95% confidence interval (CI), 0.30-4.24], transient ischemic attack (1.01, 95% CI, 0.14-6.59), and major bleeding (0.94, 95% CI, 0.02-2.77) resulted in no significant differences between the 2 interventions. Nevertheless, additional studies with robust designs and strong evidence are required to assess antiplatelet and anticoagulation drugs, dosing, timing, and outcomes in patients with carotid blunt trauma, ultimately enabling the formulation of recommendations.

Abstract
Cerebrovascular complications from blunt trauma to the skull base, though rare, can lead to potentially devastating outcomes, emphasizing the importance of timely diagnosis and management. Due to the insidious clinical presentation, subtle nature of imaging findings, and complex anatomy of the skull base, diagnosing cerebrovascular injuries and their complications poses considerable challenges. This article offers a comprehensive review of skull base anatomy and pathophysiology pertinent to recognizing cerebrovascular injuries and their complications, up-to-date screening criteria and imaging techniques for assessing these injuries, and a case-based review of the spectrum of cerebrovascular complications arising from skull base trauma. This review will enhance understanding of cerebrovascular injuries and their complications from blunt skull base trauma to facilitate diagnosis and timely treatment.

Abstract
INTRODUCTION Clinical implications of screening for blunt cerebrovascular injury (BCVI) after low-energy mechanisms of injury (LEMI) remain unclear. We assessed BCVI incidence and outcomes in LEMI versus high-energy mechanisms of injury (HEMI) patients. METHODS In this retrospective cohort study, blunt trauma adults admitted between July 2015 and June 2021 with cervical spine fractures, excluding single spinous process, osteophyte, and chronic fractures were included. Demographics, comorbidities, injuries, screening and treatment data, iatrogenic complications, and mortality were collected. Our primary end point was to compare BCVI rates between LEMI and HEMI patients. RESULTS Eight hundred sixty patients (78%) were screened for BCVI; 120 were positive for BCVI. LEMI and HEMI groups presented similar BCVI rates (12.6% versus 14.4%; P = 0.640). Compared to HEMI patients (n = 95), LEMI patients (n = 25) were significantly older (79 ± 14.9 versus 54.3 ± 17.4, P < 0.001), more likely to be on anticoagulants before admission (64% versus 23.2%, P < 0.001), and less severely injured (LEMI injury severity score 10.9 ± 6.6 versus HEMI injury severity score 18.7 ± 11.4, P = 0.001). All but one LEMI and 90.5% of the HEMI patients had vertebral artery injuries with no significant difference in BCVI grades. One HEMI patient developed acute kidney injury because of BCVI screening. Eleven HEMI patients developed BCVI-related stroke with two related mortalities. One LEMI patient died of a BCVI-related stroke. CONCLUSIONS BCVI rates were similar between HEMI and LEMI groups when screening based on cervical spine fractures. The LEMI group exhibited no screening or treatment complications, suggesting that benefits may outweigh the risks of screening and potential bleeding complications from treatment.

Abstract
Certain high-energy blunt forces may produce unstable cervical fractures with or without dislocation. In rare cases where the superior facets are dislocated, however showing a significant increase within the last decade, these types of injuries may include vertebral artery entrapment at the involvement level leading to artery dissection or occlusion. This phenomenon is usually seen at the C4-C5 and C5-C6 levels of injury. A systematic review of the literature was performed by examining online databases such as PubMed - NCBI, Web of Science, Cochrane Library, Scopus, and Embase to identify relevant scientific articles. Keywords (MeSH terms) used in the search included cervical spine injuries, cervical spine dislocation, cerebrovascular injury, vertebral artery injury, vertebral artery injury management, and incidence of vertebral artery injury. Initially, 1516 studies were identified as a primary search for screening. After excluding papers that did not fulfill the inclusion criteria, 34 studies were included in this review. Vertebral artery injury consists of a severe complication that could compromise a surgical intervention since the patient's clinical image may be unrevealing at first. Early diagnosis and correct timing constitute the golden standard for adequate treatment. This systematic review aims to summarize the current evidence for the diagnosis, management, and treatment of blunt traumatic vertebral artery injuries.

Abstract
BACKGROUND Limited research has explored the effect of Circle of Willis (CoW) anatomy among blunt cerebrovascular injuries (BCVI) on outcomes. It remains unclear if current BCVI screening and scanning practices are sufficient in identification of concomitant COW anomalies and how they affect outcomes. METHODS This retrospective cohort study included adult traumatic BCVIs at 17 level I-IV trauma centers (08/01/2017-07/31/2021). The objectives were to compare screening criteria, scanning practices, and outcomes among those with and without COW anomalies. RESULTS Of 561 BCVIs, 65% were male and the median age was 48 y/o. 17% (n = 93) had a CoW anomaly. Compared to those with normal CoW anatomy, those with CoW anomalies had significantly higher rates of any strokes (10% vs. 4%, p = 0.04), ICHs (38% vs. 21%, p = 0.001), and clinically significant bleed (CSB) before antithrombotic initiation (14% vs. 3%, p < 0.0001), respectively. Compared to patients with a normal CoW, those with a CoW anomaly also had ischemic strokes more often after antithrombotic interruption (13% vs. 2%, p = 0.02).Patients with CoW anomalies were screened significantly more often because of some other head/neck indication not outlined in BCVI screening criteria than patients with normal CoW anatomy (27% vs. 18%, p = 0.04), respectively. Scans identifying CoW anomalies included both the head and neck significantly more often (53% vs. 29%, p = 0.0001) than scans identifying normal CoW anatomy, respectively. CONCLUSIONS While previous studies suggested universal scanning for BCVI detection, this study found patients with BCVI and CoW anomalies had some other head/neck injury not identified as BCVI scanning criteria significantly more than patients with normal CoW which may suggest that BCVI screening across all patients with a head/neck injury may improve the simultaneous detection of CoW and BCVIs. When screening for BCVI, scans including both the head and neck are superior to a single region in detection of concomitant CoW anomalies. Worsened outcomes (strokes, ICH, and clinically significant bleeding before antithrombotic initiation) were observed for patients with CoW anomalies when compared to those with a normal CoW. Those with a CoW anomaly experienced strokes at a higher rate than patients with normal CoW anatomy specifically when antithrombotic therapy was interrupted. This emphasizes the need for stringent antithrombotic therapy regimens among patients with CoW anomalies and may suggest that patients CoW anomalies would benefit from more varying treatment, highlighting the need to include the CoW anatomy when scanning for BCVI.

Abstract
Cerebrovascular disease encompasses a vast array of conditions. The imaging recommendations for stroke-related conditions involving noninflammatory steno-occlusive arterial and venous cerebrovascular disease including carotid stenosis, carotid dissection, intracranial large vessel occlusion, and cerebral venous sinus thrombosis are encompassed by this document. Additional imaging recommendations regarding complications of these conditions including intraparenchymal hemorrhage and completed ischemic strokes are also discussed. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Abstract
A short cut review of the literature was carried out to examine the evidence supporting antithrombotic treatment and/or endovascular therapy to reduce mortality and/or prevent future stroke following blunt cerebrovascular injury (BCVI). Five papers were identified as suitable for inclusion using the reported search strategy. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of the best papers are tabulated. It is concluded that in patients with BCVI confirmed by CT angiography, there is limited evidence to support screening for, or treating BCVI. In confirmed BCVI where the risk of stroke is felt to outweigh the risk of bleeding, antiplatelet therapy appears to be as effective as therapeutic anticoagulation.

Abstract
BACKGROUND Management of traumatic vertebral artery injury (VAI) remains under debate. Current consensus reserves surgical or endovascular management for high-grade injury in order to prevent stroke. We sought to evaluate the factors that influence posterior fossa stroke outcomes following traumatic VAI. METHODS A search of the prospectively maintained PROOVIT trauma registry of patients older than 18 years of age with a diagnosis of VAI was performed at a level 1 trauma center from 2013 to 2019. Patient demographics, type of injury, the timing of presentation, Biffl Classification of Cerebrovascular Injury Grade score, medical management, procedural interventions, and stroke outcomes were analyzed. RESULTS VAIs were identified in 66 trauma patients were identified out of 14,323 patients entered into the PROOVIT registry. The dominant mechanism was blunt injury (91.5% vs. 8.5%, blunt versus penetrating). Nine patients presented with symptomatic ipsilateral posterior circulation strokes visible on imaging. The average Biffl classification grade was similar between the stroke and nonstroke groups (2.0 vs. 1.5; P = 0.39). The average injury severity score (ISS) between stroke and nonstroke groups was also similar (9.0 vs. 14.0; P = 0.35). All 9 patients in the stroke group had magnetic resonance imaging verification of their infarct within an average of 21.2 hr from presentation. In the stroke group, 1 patient underwent diagnostic angiography but had no intervention. In the nonstroke group, all were treated with medical management alone and none underwent vertebral artery intervention. During a mean follow-up of 14.5 months, no patients experienced a new neurological deficit. CONCLUSIONS The severity of VAI by Biffl grading and ISS are not associated with ischemic stroke at presentation following VAI. Medical management of VAI appears safe regardless of Biffl and ISS staging in this trauma population. Neurological changes related to embolic stroke were generally appreciated on presentation. Conservative medical management was sufficient to protect from secondary neurological deficit regardless of index vertebral injury.

Abstract
BACKGROUND Optimal management of traumatic extracranial cerebrovascular injuries (ECVIs) remains undefined. We sought to evaluate the factors that influence management and neurologic outcomes (stroke and brain death) following traumatic ECVI. METHODS A retrospective review of a single level 1 trauma center's prospectively maintained data registry of patients older than 18 years of age with a diagnosis of ECVI was performed from 2013 to 2019. Injuries limited to the external carotid artery were excluded. Patient demographics, type of injury, timing of presentation, Biffl Classification of Cerebrovascular Injury Grade, Injury Severity Score (ISS), and Abbreviated Injury Scale were documented. Ultimate treatments (medical management and procedural interventions) and brain-related outcomes (stroke and brain death) were recorded. RESULTS ECVIs were identified in 96 patients. The primary mechanism of injury was blunt trauma (89.5% vs. 10.5%, blunt versus penetrating), with 70 cases (66%) of vertebral artery injury and 37 cases of carotid artery injury. Treatments included vascular intervention (6.5%) and medical management (93.5%). Overall outcomes included ipsilateral ischemic stroke (29%) and brain death (6.5%). In the carotid group, vascular intervention was associated with higher Biffl grades (mean Biffl 3.17 vs. 2.23; P = 0.087) and decreased incidence of brain death (0% vs. 19%, P = 0.006), with no difference seen in ISS scores. Brain death was associated with higher ISS scores (40.29 vs. 24.17, P = 0.01), lower glascow coma score on arrival (3.57 vs. 10.63, P < 0.001), and increased rates of ischemic stroke (71% vs. 30%, P = 0.025). In the vertebral group, neither Biffl grade nor ISS were associated with treatment or outcomes. Regarding the timing of stroke in ECVI, there was no significant difference in the time from presentation to cerebral infarction between the carotid and vertebral artery groups (24.7 hr vs. 21.20 hr, P = 0.739). After this window, 98% of the ECVI cases demonstrated no further aneurysmal degeneration or new neurological deficits beyond the early time period (mean follow-up 9.7 months). CONCLUSIONS Blunt cerebrovascular injuries should be viewed distinctly in the carotid and vertebral territories. In cases of injury to the carotid artery, Biffl grade and ISS score are associated with surgical intervention and neurologic events, respectively; vertebral artery injuries did not share this association. Neurologic deficits were detected in a similar time frame between the carotid artery and the vertebral artery injury groups and both groups had rare late neurologic events.

Abstract
INTRODUCTION Blunt cerebrovascular injury (BCVI) is defined as a nonpenetrating injury to the carotid or vertebral arteries which can be highly morbid. Because BCVI is rare, most studies have been devoted to triaging trauma patients for BCVI identification, with little data available regarding the complications these patients experience after initial evaluation. Here, we analyze the association of complications during admission for BCVI patients. METHODS The National Trauma Databank was queried from 2007 to 2014 for adults ≥65 y old. Demographics, incidence of BCVI, and injury data were evaluated using univariate analysis. Rates of inpatient complications due to acutely acquired infections and strokes were evaluated using univariate and multivariable analysis. RESULTS We identified 666,815 non-BCVI and 552 BCVI patients. Patients with a BCVI were typically male, White, younger (65-75-y-old), had three or more comorbidities, and had Medicare insurance. BCVI patients had a mild head injury upon arrival at the emergency department and experienced a motor vehicle accident/fall. The median length of stay in the intensive care unit, days spent on a ventilator, and presence of polytrauma were higher among BCVI patients. BCVI patients had increased odds of experiencing a stroke and pneumonia as complications while admitted compared to their non-BCVI counterparts. CONCLUSIONS Postinjury, patients who suffered a BCVI had higher odds of stroke and pneumonia than patients who did not experience a BCVI. Additional studies are needed to determine the modifiable risk factors associated with BCVIs among aging adults.

Abstract
Objective Identifying ischemic stroke is a diagnostic challenge in the trauma subpopulation. We describe our early experience with artificial intelligence-assisted image analysis software for automatically identifying acute ischemic stroke in trauma patients. Methods Patients were retrospectively screened for (i) admission to the trauma service at a level one trauma center between 2020 and 2022, (ii) radiologist-confirmed intracranial occlusion, (iii) occlusion identified on computed tomography angiography performed within 24 hours of admission, (iv) no intracranial hemorrhage, and (v) contemporaneous analysis with the large vessel occlusion (LVO) detection program. Baseline characteristics, stroke detection, response-activation, and outcome data were summarized. Results Of 9893 trauma patients admitted, 88 (0.89%) patients had a cerebral stroke diagnosis, of which 10 patients (10/88; 11.4%) met inclusion criteria. Most patients were admitted following a fall (8/10; 80%). Six (6/10; 60.0%) patients had LVOs. The program correctly detected 83.3% (5/6) of patients, and these patients were triaged in less than one hour from arrival on average. The program did not falsely identify non-LVOs as LVOs for any patients. Conclusions Identifying adjunct tools to aid timely identification and treatment of ischemic stroke in trauma patients is necessary to increase the chances for meaningful neurological recovery. Our early experience exhibited potential for using automated software to aid occlusion identification and subsequent stroke team mobilization. Future studies in larger cohorts will expand upon these preliminary findings to establish the accuracy and clinical benefit of automated stroke detection tool integration for the trauma population.

Abstract
BACKGROUND & OBJECTIVES Blunt cerebrovascular injury (BCVI) includes carotid and/or vertebral artery injury following trauma, and conveys an increased stroke risk. We conducted a systematic review and meta-analysis to provide a comprehensive summary of prognostic factors associated with risk of stroke following BCVI. METHODS We searched the EMBASE and MEDLINE databases from January 1946 to June 2023. We identified studies reporting associations between patient or injury factors and risk of stroke following BCVI. We performed meta-analyses of odds ratios (ORs) using the random effects method and assessed individual study risk of bias using the QUIPS tool. We separately pooled adjusted and unadjusted analyses, highlighting the estimate with the higher certainty. RESULTS We included 26 cohort studies, involving 20,458 patients with blunt trauma. The overall incidence of stroke following BCVI was 7.7 %. Studies were predominantly retrospective cohorts from North America and included both carotid and vertebral artery injuries. Diagnosis of BCVI was most commonly confirmed with CT angiography. We demonstrated with moderate to high certainty that factors associated with increased risk of stroke included carotid artery injury (as compared to vertebral artery injury, unadjusted odds ratio [uOR] 1.94, 95 % CI 1.62 to 2.32), Grade III Injury (as compared to grade I or II) (uOR 2.45, 95 % CI 1.88 to 3.20), Grade IV injury (uOR 3.09, 95 % CI 2.20 to 4.35), polyarterial injury (uOR 3.11 (95 % CI 2.05 to 4.72), occurrence of hypotension at the time of hospital admission (adjusted odds ratio [aOR] 1.32, 95 % CI 0.87 to 2.03) and higher total body injury severity (aOR 5.91, 95 % CI 1.90 to 18.39). CONCLUSION Local anatomical injury pattern, overall burden of injury and flow dynamics contribute to BCVI-related stroke risk. These findings provide the foundational evidence base for risk stratification to support clinical decision making and further research.

Abstract
Traumatic brain injury is often associated with a direct or secondary neurovascular pathology. In this review, we present recent advancements in endovascular neurosurgery that enable accurate and effective vessel reconstruction with emphasis on its role in early diagnosis, the expanding use of flow diversion in pseudoaneurysms, and traumatic arteriovenous fistulas. In addition, future directions in which catheter-based interventions could potentially affect traumatic brain injury are described: targeting blood brain barrier integrity using the advantages of intra-arterial drug delivery of blood brain barrier stabilizers to prevent secondary brain edema, exploring the impact of endovascular venous access as a means to modulate venous outflow in an attempt to reduce intracranial pressure and augment brain perfusion, applying selective intra-arterial hypothermia as a neuroprotection method mitigating some of the risks conferred by systemic cooling, trans-vessel wall delivery of regenerative therapy agents, and shifting attention using multimodal neuromonitoring to post-traumatic vasospasm to further characterize the role it plays in secondary brain injury. Thus, we believe that the potential of endovascular tools can be expanded because they enable access to the "highways" governing perfusion and flow and call for further research focused on exploring these routes because it may contribute to novel endovascular approaches currently used for treating injured vessels, harnessing them for treatment of the injured brain.

Abstract
BACKGROUND AND OBJECTIVES Although blunt cerebrovascular injuries (BCVIs) are relatively common in patients with traumatic brain injuries (TBIs), uncertainty remains regarding optimal management strategies to prevent neurological complications, morbidity, and mortality. Our objectives were to characterize common care patterns; assess the prevalence of adverse outcomes, including stroke, functional deficits, and death, by BCVI grade; and evaluate therapeutic approaches to treatment in patients with BCVI and TBI. METHODS Patients with TBI and BCVI treated at our Level I trauma center from January 2016 to December 2020 were identified. Presenting characteristics, treatment, and outcomes were captured for univariate and multivariate analyses. RESULTS Of 323 patients with BCVI, 145 had Biffl grade I, 91 had grade II, 49 had grade III, and 38 had grade IV injuries. Lower-grade BCVIs were more frequently managed with low-dose (81 mg) aspirin ( P < .01), although all grades were predominantly treated with high-dose (150-600 mg) aspirin ( P = .10). Patients with low-grade BCVIs had significantly fewer complications ( P < .01) and strokes ( P < .01). Most strokes occurred in the acute time frame (<24 hours), including 10/11 (90.9%) grade IV-related strokes. Higher BCVI grade portended elevated risk of stroke (grade II odds ratio [OR] 5.3, grade III OR 12.2, and grade IV OR 19.6 compared with grade I; all P < .05). The use of low- or high-dose aspirin was protective against mortality (both OR 0.1, P < .05). CONCLUSION In patients with TBI, BCVIs impart greater risk for stroke and other associated morbidities as their severity increases. It may prove difficult to mitigate high-grade BCVI-related stroke, considering most events occur in the acute window. The paucity of late time frame strokes suggest that current management strategies do help mitigate risks.

Abstract
PURPOSE Laryngeal fracture is a rare but potentially life-threatening trauma. Fractures vary from mild to dislocated and extensive with risk of severe complications. This study investigated the occurrence, clinical characteristics and management of laryngeal fractures in the last 15 years. MATERIAL AND METHODS A retrospective population-based cohort study reviewing all laryngeal fractures at the Helsinki University Hospital in 2005-2019. Patient records and imaging studies were systematically reviewed for mode of injury, fracture type, secondary complications, treatment modality, possible airway management, length of stay, and mortality. Results were compared with corresponding data from 1995 to 2004. RESULTS Overall 80 fracture patients were recorded (5.3/year); 79% were men and mean age was 42 years (range 18-78). Altogether 91% were closed and 9% open. While unintentional traumas were most common (54%), an increasing proportion were from intentional injury (10%) or Schaefer Gr IV in severity (35%). Altogether 46% had compromised airway and 21% needed airway intervention; airway narrowing was more common with cricoid (p = 0.042) and multiple fractures (p = 0.07) and correlated positively with amount of dislocation (p = 0.001) and number of fracture lines (p = 0.006). Surgery was performed for 33%, of which 46% were Schaefer Gr IV and 62% from intentional trauma. Mortality was 1.4%. CONCLUSIONS Deliberate and violence-related laryngeal fractures have increased. These often result in more extensive injuries predisposing to compromised airway and requiring surgical intervention and longer treatment. Most fractures are still treated conservatively with good long-term outcomes. An observation period of 24 h is recommended to detect any delayed complications. Mortality remains low.

Abstract
Introduction Blunt cervical injuries rarely cause vertebral artery injuries (VAIs), such as vertebral artery (VA) dissection or occlusion. To prevent subsequent embolic infarction, embolization of the injured VA is needed before surgical fixation of the cervical spine. However, evidence on endovascular treatment for asymptomatic low-grade VAIs with blunt traumatic cervical injury is insufficient. Case Report In the present case, a 79-year-old Japanese man presented tetraparesis after falling while walking. Digital subtraction angiography showed no intimal flap and only slight stenosis of the right VA. Embolization was not performed before spinal decompression surgery for this low-grade injury. However, on the 3rd day after surgery, diffuse-weighted imaging showed dot-like high signal intensity in the right thalamus and right posterior lobe, and magnetic resonance angiography (MRA) showed near occlusion of the right VA. 8 days after surgery, MRA showed recanalization of the right VA flow. We performed VA embolization to prevent emboli scattering to the distal region during recanalization of the intracranial blood flow. Conclusion According to the relevant literature, prophylactic embolization may be indicated to prevent the embolic infarction not only in cases of VA occlusion requiring fixation of the cervical spine but also in cases of low-grade VAIs in which fixation is not required. Embolization of the VA before spinal surgery might be an aggressive treatment strategy that avoids serious embolic infarction disorder after VAIs.

Abstract
BACKGROUND Digital subtraction angiography (DSA) is the gold standard radiologic modality in blunt cerebrovascular injury (BCVI). However, computerized tomography angiography (CTA) is primarily used in modern practice with CTA's widespread availability and the decreased stroke rate with CTA use. The frequency and indications for DSA in BCVI is undefined. We hypothesized that DSA use in internal carotid artery (ICA) BCVI would be infrequent and dependent on radiologic features. METHODS This was a post hoc analysis of an EAST multicenter, prospective, observational trial of 16 trauma centers for stroke factors in BCVI. ICA BCVI was divided into those undergoing DSA and not undergoing DSA (no-DSA). Only ICA BCVI was included. RESULTS 332 ICA BCVI were included, 221 (66.6%) no-DSA and 111 (33.4%) DSA. Lower hospital trauma volume, non-urban environment, and non-academic status were associated with DSA use (all P ≤ .001). BCVI grade (P = .02) and presence of luminal stenosis (P = .005) were associated with DSA use while pseudoaneurysm presence was not. Median time to DSA was 1 hour. The most common indication for angiography was to determine the presence of injury in 71 (64%) ICA BCVI, followed by determining grade of injury in 16 (14.4%) and concerning imaging characteristics in 12 (10.8%). BCVI grade on initial imaging and on DSA were equivalent in 94 (84.7%) ICA BCVI. DISCUSSION DSA is frequently used in ICA BCVI, primarily early in the hospital course for injury diagnosis and grade determination. DSA appears primarily driven by hospital type, BCVI grade, and luminal stenosis.

Abstract
BACKGROUND AND PURPOSE Screening patients with trauma for blunt cerebrovascular injury with neck CTA is a common practice, but there remains disagreement regarding which patients should be screened. We reviewed adult blunt cerebrovascular injury data from a level 1 trauma center to investigate whether screening is warranted in low-mechanism trauma. MATERIALS AND METHODS We reviewed all neck CTAs performed on adult trauma patients in the emergency department during the 2019 calendar year. Clinical and imaging risk factors for blunt cerebrovascular injury, trauma mechanism, initial neck CTA interpretations, results from subsequent CTA and DSA studies, antiplatelet and anticoagulant treatments, and outcome data were recorded. RESULTS One thousand one hundred thirty-six neck CTAs met the inclusion criteria, of which 965 (85%) were interpreted as having negative findings; 125, as having indeterminate findings (11%); and 46, as having positive findings (4%). Review of subsequent imaging and clinical documentation led to classification of 40 indeterminate studies (32%) as true-positives and 85 (68%) as false-positives. Blunt cerebrovascular injury was identified in 77 (12.6%) cases meeting and in 9 (1.7%) cases not meeting the expanded Denver criteria. The subset of 204 low-mechanism trauma cases (ground-level falls, blunt assaults, and low-impact motor vehicle collisions) not meeting the expanded Denver criteria (18% of the entire data set) could have been excluded from screening with 1 questionable injury and 0 ischemic strokes missed and 12 false-positive cases prevented. CONCLUSIONS We advocate reservation of blunt cerebrovascular injury screening in low-mechanism trauma for patients meeting the expanded Denver criteria. Further research is needed to determine the behavior of indeterminate cases and to establish criteria for separating true-positive from false-positive findings.

Abstract
BACKGROUND The risk-benefit balance of antithrombotic therapy administration for blunt cerebrovascular injuries (BCVI) patients with concomitant injuries at high risk for bleeding is an ongoing therapeutic conundrum for trauma clinicians. We performed a systematic review to assess the reported efficacy and safety of treatment in this population with respect to prevention of ischemic stroke and risk of hemorrhagic complications. STUDY DESIGN A systematic electronic literature search of MEDLINE, EMBASE, Cochrane Library, and Web of Science databases was performed from January 1, 1996 to December 31, 2021. Studies were included if they reported treatment-stratified clinical outcomes after antithrombotic therapy in BCVI patients with concomitant injuries at high risk of bleeding into a critical site. Data were extracted from selected studies by two independent reviewers, including the main outcomes of interest were BCVI-related ischemic stroke rates and rates of hemorrhagic complications. RESULTS Of the 5,999 studies reviewed, 10 reported on the effects of treating BCVI patients with concurrent traumatic injuries and were included for review. In the pooled data, among patients with BCVI and concomitant injury who received any form of antithrombotic therapy, the BCVI-related stroke rate was 7.6%. The subgroup of patients who did not receive therapy had an overall BCVI-related stroke rate of 34%. The total rate of hemorrhagic complications in the treated population was 3.4%. CONCLUSIONS In BCVI patients with concomitant injuries at high risk for bleeding, antithrombotic use reduces the risk of ischemic strokes with a low reported risk of serious hemorrhagic complications.

J Vasc Surg 2023; 78:788-796.e6. [PMID: 37318429 DOI: 10.1016/j.jvs.2023.05.031] [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: 05/01/2023] [Revised: 05/15/2023] [Accepted: 05/17/2023] [Indexed: 06/16/2023]
Abstract
OBJECTIVE Cerebrovascular accidents (CVA) are potential sequelae of blunt cerebrovascular injuries (BCVI). To minimize their risk, medical therapy is used commonly. It is unclear if anticoagulant or antiplatelet medications are superior for decreasing CVA risk. It is also unclear as to which confer fewer undesirable side effects specifically in patients with BCVI. The aim of this study was to compare outcomes between nonsurgical patients with BCVI with hospital admission records who were treated with anticoagulant medications and those who were treated with antiplatelet medications. METHODS We performed a 5-year (2016-2020) analysis of the Nationwide Readmission Database. We identified all adult trauma patients who were diagnosed with BCVI and treated with either anticoagulant or antiplatelet agents. Patients who were diagnosed with index admission CVA, intracranial injury, hypercoagulable states, atrial fibrillation, and or moderate to severe liver disease were excluded. Those who underwent vascular procedures (open and/or endovascular approaches) and or neurosurgical treatment were also excluded. Propensity score matching (1:2 ratio) was performed to control for demographics, injury parameters, and comorbidities. Index admission and 6-month readmission outcomes were examined. RESULTS We identified 2133 patients with BCVI who were treated with medical therapy; 1091 patients remained after applying the exclusion criteria. A matched cohort of 461 patients (anticoagulant, 159; antiplatelet, 302) was obtained. The median patient age was 72 years (interquartile range [IQR], 56-82 years), 46.2% of patients were female, falls were the mechanism of injury in 57.2% of cases, and the median New Injury Severity Scale score was 21 (IQR, 9-34). Index outcomes with respect to (1) anticoagulant treatments followed by (2) antiplatelet treatments and (3) P values are as follows: mortality (1.3%, 2.6%, 0.51), median length of stay (6 days, 5 days; P < .001), and median total charge (109,736 USD, 80,280 USD, 0.12). The 6-month readmission outcomes are as follows: readmission (25.8%, 16.2%, <0.05), mortality (4.4%, 4.6%, 0.91), ischemic CVA (4.9%, 4.1%, P = not significant [NS]), gastrointestinal hemorrhage (4.9%, 10.2%, 0.45), hemorrhagic CVA (0%, 0.41%, P = NS), and blood loss anemia (19.5%, 12.2%, P = NS). CONCLUSIONS Anticoagulants are associated with a significantly increased readmission rate within 6 months. Neither medical therapy is superior to one another in the reduction of the following: index mortality, 6-month mortality, and 6-month readmission with CVA. Notably, antiplatelet agents seem to be associated with increased hemorrhagic CVA and gastrointestinal hemorrhage on readmission, although neither association is statistically significant. Still, these associations underscore the need for further prospective studies of large sample sizes to investigate the optimal medical therapy for nonsurgical patients with BCVI with hospital admission records.

Abstract
BACKGROUND Non-penetrating head and neck trauma is associated with extracranial traumatic vertebral artery injury (eTVAI) in approximately 1-2% of cases. Most patients are initially asymptomatic but have an increased risk for delayed stroke and mortality. Limited evidence is available to guide the management of asymptomatic eTVAI. As such, we sought to investigate national practice patterns regarding screening, treatment, and follow-up domains. METHODS A cross-sectional, electronic survey was distributed to members of the Canadian Neurosurgical Society and Canadian Spine Society. We presented two cases of asymptomatic eTVAI, stratified by injury mechanism, fracture type, and angiographic findings. Screening questions were answered prior to presentation of angiographic findings. Survey responses were analyzed using descriptive statistics. RESULTS One hundred-eight of 232 (46%) participants, representing 20 academic institutions, completed the survey. Case 1: 78% of respondents would screen for eTVAI with computed topography angiography (CTA) (97%), immediately (88%). The majority of respondents (97%) would treat with aspirin (89%) for 3-6 months (46%). Respondents would follow up clinically (89%) or radiographically (75%), every 1-3 months. Case 2: 73% of respondents would screen with CTA (96%), immediately (88%). Most respondents (94%) would treat with aspirin (50%) for 3-6 months (35%). Thirty-six percent of respondents would utilize endovascular therapy. Respondents would follow up clinically (97%) or radiographically (89%), every 1-3 months. CONCLUSION This survey of Canadian practice patterns highlights consistency in the approach to screening, treatment, and follow-up of asymptomatic eTVAI. These findings are relevant to neurosurgeons, spinal surgeons, stroke neurologists, and neuro-interventionalists.

Abstract
Background There is no established treatment strategy for traumatic vertebral artery occlusion that does not require cervical spine repair surgery. Case Description A 49-year-old man was brought to our hospital with traffic trauma. Fractures were observed in the left lateral mass and transverse process of Atlas and the left vertebral artery was occluded at the level of the foramen transversum of Atlas. No acute cerebral infarction was observed. Because the cervical spinal cord was not compressed by the fracture, no repair surgery was performed. Continuous intravenous heparin and oral aspirin were started for traumatic vertebral artery occlusion. Thereafter, the left vertebral artery spontaneously recanalized, but no cerebral infarction was observed. The patient was discharged home on day 16 of injury. Four days later, however, he was brought to our hospital with nausea and lightheadedness. Acute cerebral infarction was observed in the left posterior inferior cerebellar artery territory and a thrombus in the left vertebral artery V4 segment. Parent artery occlusion was performed to prevent further cerebral infarction due to distal embolization of the thrombus. No further cerebral infarction occurred after the operation and the patient was discharged home with a modified Rankin scale score of 1. Conclusion In cases of traumatic vertebral artery occlusion without an occlusive mechanism, parent artery occlusion may be considered in terms of recanalization risk, regardless of the need for repair surgery.

Abstract
OBJECTIVES While methods of endovascular carotid artery stenting have improved over time, concerns surrounding the safety and efficacy of stenting for blunt carotid injury (BCI) remain. This study aims to present our approach to carotid artery stenting (CAS) by incorporating new technologies such as flow-diverting stents and circuits. METHODS There is no robust evidence to support routine carotid artery stenting; however, there are several therapeutic options and approaches for treating BCI that currently require an individualized approach. Endovascular stenting and specific stent selection are largely dictated by the disease process the surgeon intends to treat. We will discuss patient selection, medical management, and the most common revascularization techniques, including transfemoral stenting, trans-carotid arterial revascularization using flow reversal, and stent-assisting coiling. RESULTS It must be stressed that endovascular intervention is not an alternative to or preclusive of antithrombotic or anticoagulant therapy. In the setting of BCI, transfemoral CAS is most appropriate in patients who are symptomatic, have a rapidly progressing or large lesion, and do not have a soft thrombus present due to risk of embolism. Unlike transfemoral CAS, TCAR offers an elegant solution for embolic protection when patients have a soft thrombus present. In the case of a large pseudoaneurysm, we perform stent-assisted coiling. CONCLUSIONS We practice selective endovascular intervention, stenting lesions that are flow-limiting or have large or rapidly expanding pseudoaneurysms, and only in patients for whom anticoagulation and antiplatelet agents are not contraindicated. As technology and investigation progress, the concerns regarding the safety and the role of endovascular intervention in the treatment of BCI will be more clearly defined.

Abstract
Trauma to the head and neck region can have serious consequences for vital organs such as the brain, and injuries to blood vessels can cause permanent neurological damage or even death. Thus, prompt treatment of head and neck vessels is crucial. Although the level of evidence is moderate, an increasing amount of research indicates that endovascular treatments can be a viable alternative to traditional surgery or medical management. Embolization or reconstructive endovascular procedures can significantly improve patient outcomes. This article provides an overview of various endovascular options available for specific clinical scenarios, along with examples of cases in which they were employed.

Abstract
OBJECTIVE Blunt cervical vascular injury (BCVI) is a non-penetrating trauma to the carotid and/or vertebral vessels following a direct injury to the neck or by the shearing of the cervical vessels. Despite its potentially life-threatening nature, important clinical features of BCVI such as typical patterns of co-occurring injuries for each trauma mechanism are not well known. To address this knowledge gap, we described the characteristics of patients with BCVI to identify the pattern of co-occurring injuries by common trauma mechanisms. METHODS This is a descriptive study using a Japanese nationwide trauma registry from 2004 through 2019. We included patients aged ≥13 years presenting to the emergency department (ED) with BCVI, defined as a blunt trauma to any of the following vessels: common/internal carotid artery, external carotid artery, vertebral artery, external jugular vein, and internal jugular vein. We delineated characteristics of each BCVI classified according to three damaged vessels (common/internal carotid artery, vertebral artery, and others). In addition, we applied network analysis to unravel patterns of co-occurring injuries among patients with BCVI by four common trauma mechanisms (car accident, motorcycle/bicycle accident, simple fall, and fall from a height). RESULTS Among 311,692 patients who visited the ED for blunt trauma, 454 (0.1%) patients had BCVI. Patients with common/internal carotid artery injuries presented to the ED with severe symptoms (e.g., the median Glasgow Coma Scale was 7) and had high in-hospital mortality (45%), while patients with vertebral artery injuries presented with relatively stable vital signs. Network analysis showed that head-vertebral-cervical spine injuries were common across four trauma mechanisms (car accident, motorcycle/bicycle accident, simple fall, and fall from a height), with co-occurring injuries of the cervical spine and vertebral artery being the most common injuries due to falls. In addition, common/internal carotid artery injuries were associated with thoracic and abdominal injuries in patients with car accidents. CONCLUSIONS Based on analyses of a nationwide trauma registry, we found that patients with BCVI had distinct patterns of co-occurring injuries by four trauma mechanisms. Our observations provide an important basis for the initial assessment of blunt trauma and could support the management of BCVI.

Abstract
Objectives Our understanding of blunt cerebrovascular injury (BCVI) has changed significantly in recent decades, resulting in a heterogeneous description of diagnosis, treatment, and outcomes in the literature which is not suitable for data pooling. Therefore, we endeavored to develop a core outcome set (COS) to help guide future BCVI research and overcome the challenge of heterogeneous outcomes reporting. Methods After a review of landmark BCVI publications, content experts were invited to participate in a modified Delphi study. For round 1, participants submitted a list of proposed core outcomes. In subsequent rounds, panelists used a 9-point Likert scale to score the proposed outcomes for importance. Core outcomes consensus was defined as >70% of scores receiving 7 to 9 and <15% of scores receiving 1 to 3. Feedback and aggregate data were shared between rounds, and four rounds of deliberation were performed to re-evaluate the variables not achieving predefined consensus criteria. Results From an initial panel of 15 experts, 12 (80%) completed all rounds. A total of 22 items were considered, with 9 items achieving consensus for inclusion as core outcomes: incidence of postadmission symptom onset, overall stroke incidence, stroke incidence stratified by type and by treatment category, stroke incidence prior to treatment initiation, time to stroke, overall mortality, bleeding complications, and injury progression on radiographic follow-up. The panel further identified four non-outcome items of high importance for reporting: time to BCVI diagnosis, use of standardized screening tool, duration of treatment, and type of therapy used. Conclusion Through a well-accepted iterative survey consensus process, content experts have defined a COS to guide future research on BCVI. This COS will be a valuable tool for researchers seeking to perform new BCVI research and will allow future projects to generate data suitable for pooled statistical analysis with enhanced statistical power. Level of evidence Level IV.

Abstract
BACKGROUND While blunt cerebrovascular injury (BCVI) is a rare complication of blunt trauma, it is associated with significant morbidity and mortality. In the pediatric population, unique anatomy and development require screening criteria that accurately diagnose these injuries while limiting unwarranted radiation. METHODS We searched Medline OVID, EMBASE, and Cochrane Library databases for studies that investigated the risk factors of BCVI in individuals younger than 18 years of age. We adhered to the Preferred Reporting Items in Systematic Reviews and Meta-Analyses (PRISMA) guidelines and assessed the quality of each study using the Newcastle-Ottawa Scale. We compared key characteristics of the papers, including incidence of BCVI, incidence of risk factors, and statistical significance of risk factors. RESULTS Of 1304 studies, 16 met the inclusion criteria. Of these, 15 were retrospective cohort studies and one was a retrospective case control study. Most of the studies included all pediatric blunt trauma admissions, but four only included those which underwent imaging, one only included those with cervical seatbelt sign, and one excluded those who did not survive 24-h post-admission. The ages included as pediatric varied between papers. Papers examined different risk factors and reported differing statistical significances. Though no single risk factor was found to be statistically significant in every study, cervical spine and skull fractures were found to be significant by most. Maxillofacial fractures, depressed GCS score, and stroke were found to be statistically significant by multiple studies. Twelve studies examined cervical soft tissue injury, and none found it to be statistically significant. CONCLUSIONS The risk factors most found to be statistically significant for BCVI were cervical spine fracture (10/16 studies), skull fracture (9/16), maxillofacial fractures (7/16), depressed GCS score (5/16), and stroke (5/16). There is a need for prospective studies on this topic. LEVEL OF EVIDENCE Level III, Systematic Review.

Abstract
BACKGROUND Higher blunt cerebrovascular injury (BCVI) grade and lack of medical therapy are associated with stroke. Knowledge of stroke risk factors specific to individual grades may help tailor BCVI therapy to specific injury characteristics. METHODS A post-hoc analysis of a 16 center, prospective, observational trial (2018-2020) was performed including grade 1 internal carotid artery (ICA) BCVI. Repeat imaging was considered the second imaging occurrence only. RESULTS From 145 grade 1 ICA BCVI included, 8 (5.5%) suffered a stroke. Grade 1 ICA BCVI with stroke were more commonly treated with mixed anticoagulation and antiplatelet therapy (75.0% vs 9.6%, P <.001) and less commonly antiplatelet therapy (25.0% vs 82.5%, P = .001) compared to injuries without stroke. Of the 8 grade 1 ICA BCVI with stroke, 4 (50.0%) had stroke after medical therapy was started. In comparing injuries with resolution at repeat imaging to those without, stroke occurred in 7 (15.9%) injuries without resolution and 0 (0%) injuries with resolution (P = .005). At repeat imaging in grade 1 ICA BCVI with stroke, grade of injury was grade 1 in 2 injuries, grade 2 in 3 injuries, grade 3 in 1 injury, and grade 5 in one injury. DISCUSSION While the stroke rate for grade 1 ICA BCVI is low overall, injury persistence appears to heighten stroke risk. Some strokes occurred despite initiation of medical therapy. Repeat imaging is needed in grade 1 ICA BCVI to evaluate for injury progression or resolution.

Abstract
Blunt and penetrating vascular injuries of the head and neck can represent life-threatening emergencies that require accurate detection to prevent devastating and long-lasting consequences. Implementing appropriate screening criteria to indicate imaging studies is crucial as there is a variable latent time before the onset of clinical manifestations. Computed tomography angiography, MR imaging, and digital subtraction angiography represent the imaging modalities of choice to evaluate vascular injuries. The aim of this review is to provide a description of the different types of vascular injuries, describe the importance of each imaging modality, and recognize the imaging appearance of traumatic vessel injury.

Abstract
Young adults who present to the ED with neck pain following non-penetrating, seemingly trivial trauma to the neck, are at risk of neck artery dissection and subsequent stroke. Sport-related neck injury is the chief cause. Physical examination may often be unremarkable, and although there may be reluctance to expose young patients to radiation, radiological imaging is central to making a diagnosis of arterial wall disruption. A comprehensive literature search was performed in relation to neck artery dissection, and the evidence was scrutinised. We discuss the typical mechanism of injury, symptoms, anatomical considerations and clinical aids in diagnosis of neck artery dissection. Although the incidence is low, neck artery dissection has a mortality of 7%. As such, it is important for front-line physicians to have a high suspicion of the diagnosis and a low threshold to organise radiological examinations, specifically computerised tomography. Early detection of neck artery dissection will trigger clinical protocols that call for multi-disciplinary team management of this condition. In general, guideline-based recommendation for the management of neck artery dissection involving an intimal flap is by anti-platelet therapy while treatment of neck artery dissection that results in a pseudo-aneurysm or thrombosis is managed by surgical intervention or endovascular techniques. Close follow up combined with antithrombotic treatment is recommended in these individuals, the goal being prevention of stroke.

Abstract
AIM To assess whether routine cerebrovascular imaging is required in all major trauma (MT) patients. MATERIALS AND METHODS All MT patients with cerebrovascular imaging between January 2015 and December 2020 were included in the study. Data were collated regarding the type of indication for computed tomography (CT) angiography imaging, time interval from the initial trauma, relevant trauma diagnoses on initial trauma imaging, and CT angiography. Findings, such as aneurysms, vascular malformations, luminal thrombus, venous sinus thrombosis, or vascular injury, were collated. Subsequent treatment with anti-coagulants/anti-platelets or surgical/radiological intervention was noted. Follow-up imaging was assessed for residual injury or complications. RESULTS Two hundred and fifty of the 6,251 MT patients underwent dedicated cerebrovascular imaging and were included in the study. Of these 41 (16.4%) had cervical artery or venous sinus injury. Further positive vascular findings were identified in 25/250 patients who presented with an incidental stroke or a vascular abnormality and were mislabelled as MT patients at presentation. One patient with a carotid injury subsequently died following a large infarction. Another patient with vertebral artery injury suffered a non-lethal stroke. No patients underwent surgery or intervention. CONCLUSION The present study showed that the overall incidence of detected blunt cerebrovascular injuries was very low (0.6%) and even lower for symptomatic vascular injury (0.03%). Routine cerebrovascular imaging is not recommended in all MT trauma patients, but instead, a continued case-by-case basis should be considered.

Abstract
Background Blunt cerebrovascular injuries are rare and serious complications of trauma that can lead to cerebral vascular dissection or aneurysm. Improving awareness of blunt cerebrovascular injuries and using computed tomography angiography to pre-screen patients at high risk is recommended by current guidelines to prevent the occurrence of ischemic stroke complications. Case description A 32-year-old male patient was admitted to the hospital following neck trauma accompanied by stroke symptoms. Imaging revealed intimal injury of the right common carotid artery and acute cerebral infarction. After an endarterectomy and repair, the vascular lumen obstruction resolved, blood flow was restored, and the patient's condition stabilized. Conclusion Blunt cerebrovascular injury has been seriously neglected in clinical practice. Delayed or under-diagnosis of blunt cerebrovascular injury can result large strokes. Standardized treatment protocols, which include the screening and grading of blunt cerebrovascular injury, may reduce the risk of permanent neurological dysfunction, and even death, in patients.

Abstract
Diagnostic Criteria Study BACKGROUND: The morbidity and mortality associated with ischemic stroke attributable to blunt cerebrovascular injury (BCVI) warrant aggressive screening. The Denver Criteria (DC) and Expanded Denver Criteria (eDC) have imprecise elements that can be difficult and subjective in application and can delay or prevent screening. We hypothesize these screening criteria lack adequate ability to consistently identify BCVI and that the use of a liberalized screening approach with CT angiography (CTA) is superior without increasing risk of acute kidney injury (AKI). METHODS This was a multi-institutional retrospective cohort study of trauma patients who presented between 2015-2020 with radiographically confirmed BCVI diagnosed using each institutions' liberalized screening protocol, defined as automatic CTA of the head and neck for all patients undergoing head and neck CT. Outcomes of interest included AKI, stroke, and death due to BCVI. Outcomes were reported as frequency, percent, and 95% confidence interval as calculated by the Clopper-Pearson method. Incidence of medical follow-up within 1 year of first medical visit was quantified as the median and inter-quartile range of days to follow-up visit. RESULTS We identified 433 BCVI patients with a mean age of 45.2 (standard deviation 18.9) years, 256 men and 177 women, 1.73 m (0.10) tall, and weighed 80.3 kg (20.3). Forty-one patients had strokes (9.5% [95% confidence interval 6.9, 12.6] and 12 patients (2.8% [1.4, 4.5]) had mortality attributable to BCVI. Of 433 total cases, 132 (30.5% [26.2, 35.1]) would have been missed by DC and 150 (34.6% [30.2, 39.3]) by eDC. Incidence of AKI in our BCVI population was 6 (1.4% [0.01, 3.0]). CONCLUSIONS BCVI would be missed over 30% of the time using the DC and eDC compared to liberalized use of screening CTA. Risk of AKI due to CTA did not occur at a clinically meaningful level, supporting liberal CTA screening.

Abstract
BACKGROUND Blunt cerebrovascular injury (BCVI), defined as blunt traumatic injury to the carotid or vertebral arteries, is associated with significant risk of stroke and mortality. Cervical spine trauma is a recognized risk factor for BCVI. OBJECTIVE The objective of this study was to identify significant predictors of BCVI and its sequelae in patients with known cervical spine injury. METHODS Patients from 2007 to 2018 with blunt cervical spine injury diagnoses were identified in the National Trauma Data Bank. Multivariable logistic regression models were used to identify patient baseline and injury characteristics associated with BCVI, stroke, and mortality. RESULTS We identified 229,254 patients with cervical spine injury due to blunt trauma. The overall rate of BCVI was 1.6%. Factors associated with BCVI in patients with cervical spine injury included lower Glasgow Coma Scale, motor vehicle crash, higher Injury Severity Score, concomitant traumatic brain or spinal cord injury, and current smoking status. BCVI was a strong predictor of stroke (odds ratio, 8.2; 95% confidence interval, 5.7-12.0) and was associated with mortality (odds ratio, 1.7; 95% confidence interval, 1.3-2.2). Stroke occurred in 3.3% of patients with BCVI versus 0.02% for patients without BCVI. CONCLUSIONS While BCVI is rare following cervical spine injury due to blunt trauma, it is a significant predictor of stroke and mortality. The risk factors associated with BCVI, stroke, and mortality identified here should be used in the development of more effective predictive tools to improve care.

Abstract
STUDY DESIGN Systematic Review. OBJECTIVES Vertebral Artery Injury (VAI) is a potentially serious complication of cervical spine fractures. As many patients can be asymptomatic at the time of injury, the identification and diagnosis of VAI can often prove difficult. Due to the high rates of morbidity and mortality associated with VAI, high clinical suspicion is paramount. The purpose of this review is to elucidate incidence, diagnosis, treatment and outcomes of VAI associated with cervical spine injuries. METHODS A systematic search of electronic databases was performed using 'PUBMED', 'EMBASE','Medline (OVID)', and 'Web of Science, for articles pertaining to traumatic cervical fractures with associated VAI. RESULTS 24 studies were included in this systematic review. Data was included from 48 744 patients. In regards to the demographics of the focus groups that highlighted information on VAI, the mean average age was 46.6 (32.1-62.6). 75.1% (169/225) were male and 24.9% (56/225) were female. Overall incidence of VAI was 596/11 479 (5.19%). 190/420 (45.2%) of patients with VAI had fractures involving the transverse foramina. The right vertebral artery was the most commonly injured 114/234 (48.7%). V3 was the most common section injured (16/36 (44.4%)). Grade I was the most common (103/218 (47.2%)) injury noted. Collective acute hospital mortality rate was 32/226 (14.2%), ranging from 0-26.2% across studies. CONCLUSION VAI secondary to cervical spine trauma has a notable incidence and high associated mortality rates. The current available literature is limited by a low quality of evidence. In order to optimise diagnostic protocols and treatment strategies, in addition to reducing mortality rates associated with VAI, robust quantitative and qualitative studies are needed.

Abstract
The intracranial artery dissection (IAD) is an uncommon but life-threatening disease. The IAD would develop a significant cerebral infarction due to unrecognized contrecoup brain injury. We report a 53-year-old man fell to develop blunt cerebrovascular injuries (BCVIs) more than 2 months ago. During his rehabilitation, he often had a transient left headache and underwent short-term right limb weakness twice, but he did not care. He was hospitalized again because of suffering right limb weakness for more than 4 h. The brain computed tomography angiography (CTA) showed subtotal occlusion of the left middle cerebral artery M1 segment, and the vascular morphology displayed the IAD. The patient was then treated with balloon dilation and a self-expanding stent. This case highlights that IAD may show delayed onset with no initial typical symptom. By early detecting of abnormal signs and symptoms, serious traumatic brain injury may be avoided.

We describe the case of a 28-year-old patient who presented with an ischemic stroke secondary to a stab wound to the neck that affected the vertebral artery. A physical examination revealed neurological deterioration (Glasgow 8/15), a sutured neck wound, no palpable hematoma, no thrills, and no active bleeding. A computed tomography angiography revealed a left vertebral artery arteriovenous fistula with a component of a pseudoaneurysm, for which a neurointerventional consultation was carried out. Due to neurological compromise, the airway was secured, and because the case involved a posterior fossa infarction with compression of the fourth ventricle and obstructive secondary hydrocephalus, an external ventricular shunt was inserted by neurosurgery. A fistula occlusion was performed with five Axium coils and a vial of Squid 12; the vertebral artery was catheterized, and a craniotomy was performed to manage hydrocephalus with a 12-mm H2O collecting system. The patient was discharged on the tenth day after admission with sequelae of left hemiparesis (predominantly brachial) and no other deficits. There was no hemorrhagic transformation on the control computed tomography scans and no further complications.

Abstract
Internal carotid artery dissection (ICAD) represents the cause of ictus cerebri in about 20% of all cases of cerebral infarction among the young adult population. ICAD could involve the extracranial and intracranial internal carotid artery (ICA). It could be spontaneous (SICAD) or traumatic (TICAD). It has been estimated that carotid injuries could complicate the 0,32% of cases of general blunt trauma and the percentage seems to be higher in cases of severe multiple traumas. TICAD is diagnosed when neurological symptoms have already occurred, and it could have devastating consequences, from permanent neurological impairment to death. Thus, even if it is a rare condition, a prompt diagnosis is essential. There are no specific guidelines regarding TICAD screening. Nevertheless, TICAD should be taken into consideration when a young adult or middle-aged patient presents after severe blunt trauma. Understanding which kind of traumatic event is most associated with TICAD could help clinicians to direct their diagnostic process. Herein, a review of the literature concerning TICAD has been carried out to highlight its correlation with specific traumatic events. TICAD is mostly correlated to motor vehicle accidents (94/227), specifically to car accidents (39/94), and to direct or indirect head and cervical trauma (76/227). As well, a case report is presented to discuss TICAD forensic implications.

Abstract
Objectives Current guidelines for screening for blunt cerebrovascular injury (BCVI) are commonly based on the expanded Denver criteria, a set of risk factors that identifies patients who require CT-angiographic (CTA) screening for these injuries. Based on previously published data from our center, we have adopted a more liberal screening guideline than those outlined in the expanded Denver criteria. This entails routine CTA of the neck for all blunt trauma patients already undergoing CT of the cervical spine and/or CTA of the chest. The aim of this study was to analyze the incidence of patients with BCVI who did not meet any of the risk factors included in the expanded Denver criteria. Methods A retrospective review of all patients diagnosed with BCVI between June 2014 and December 2019 at a Level I Trauma Center were identified from the trauma registry. Medical records were reviewed for the presence or absence of risk factors as outlined in the expanded Denver criteria. Demographic data, time to CTA and treatment, BCVI grade, Glasgow Coma Scale and Injury Severity Score were collected. Results During the study period, 17 054 blunt trauma patients were evaluated, and 29% (4923) underwent CTA of the neck to screen for BCVI. 191 BCVIs were identified in 160 patients (0.94% of all blunt trauma patients, 3.25% of patients screened with CTA). 16% (25 of 160) of patients with BCVI had none of the risk factors outlined in the Denver criteria. Conclusion Our findings indicate that reliance on the expanded Denver criteria alone for BCVI screening will result in missed injuries. We recommend CTA screening in all patients with blunt trauma undergoing CT of the cervical spine and/or CTA of the chest to minimize this risk. Level of evidence Level III, therapeutic/care management.

Abstract
This case report documents treatment of a 32-year-old male patient after being extricated from an extensively damaged motor vehicle after a collision. On first presentation, the patient had a Glascow Coma Score of 14 and a pan-scan revealed a severely comminuted fracture of the proximal left femoral shaft, a fracture of the left patella, and multiple rib fractures. A neurological exam on a later evaluation showed global aphasia and sharp decline in movements of the right upper and lower extremities even with painful stimuli. A CT Angiography of the head and neck was obtained and revealed evidence of occlusion in the upper cervical segment and proximal petrous segment of the left internal carotid artery (ICA). Two 6x40mm precise stents were placed restoring normal intracranial flow to the patient's left ICA. The patient was discharged having sensation and motor function in all extremities and with resolved aphasia and no neurologic deficits.

Abstract
BACKGROUND Untreated blunt cerebrovascular injuries (BCVIs) are associated with high rates of death and disability due to stroke. We assessed alignment of clinical practice at our centre with current recommendations for management of BCVIs and examined rates of new and recurrent in-hospital stroke. METHODS We retrospectively reviewed the BC Trauma Registry to identify all adult (age > 18 yr) patients with trauma with BCVIs at the largest level 1 trauma centre in British Columbia, Canada, from Apr. 1, 2013, to Mar. 31, 2018. We evaluated the registry, hospital databases and patient charts to assess alignment with guidelines for early initiation of appropriate antithrombotic therapy and follow-up imaging, and to ascertain short-term outcomes. RESULTS A total of 186 patients met the inclusion criteria. Just over half of BCVIs (97 [52.2%]) were Biffl grade 1-2. The majority of patients were treated with acetylsalicylic acid monotherapy (144/162 [88.9%]) or low-molecular-weight heparin (2/162 [1.2%]). Although guidelines recommend repeat imaging at 7-10 days to reassess the injury and guide duration of therapy, only 61/171 patients (35.7%) underwent repeat imaging within 7 days. Neuroimaging within 3 months after injury showed brain infarction in 29 patients (15.6%). CONCLUSION Antithrombotic therapy was initiated in the majority of eligible patients with BCVIs, but completion of follow-up imaging and documentation of clear outpatient care plans were suboptimal. This finding shows the need for routine multidisciplinary management to facilitate standardization of care for this complex population.

Abstract
Introduction: Traumatic carotid artery dissections (CAD) are rare but produce potentially
devastating injuries. Most patients develop symptoms within 72 hours of traumatic injury.
Case Report: We report the case of a 33-year-old, previously healthy male who presented to the emergency department for evaluation of transient, right-sided facial droop with visual changes. His symptoms began 12 days after falling off a scooter. Imaging revealed an extracranial internal CAD.
Conclusion: Symptoms of CAD may present weeks after blunt trauma, making clinical diagnosis difficult. Clinicians must have high suspicion for vascular injury and consider neuroimaging in cervical flexion/extension injuries.

Development and validation of machine learning models for the prediction of blunt cerebrovascular injury in children. J Pediatr Surg 2022; 57:732-738. [PMID: 34872731 DOI: 10.1016/j.jpedsurg.2021.11.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 11/05/2021] [Accepted: 11/10/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Blunt cerebrovascular injury (BCVI) is a rare finding in trauma patients. The previously validated BCVI (Denver and Memphis) prediction model in adult patients was shown to be inadequate as a screening option in injured children. We sought to improve the detection of BCVI by developing a prediction model specific to the pediatric population. METHODS The National Trauma Databank (NTDB) was queried from 2007 to 2015. Test and training datasets of the total number of patients (885,100) with complete ICD data were used to build a random forest model predicting BCVI. All ICD features not used to define BCVI (2268) were included within the random forest model, a machine learning method. A random forest model of 1000 decision trees trying 7 variables at each node was applied to training data (50% of the dataset, 442,600 patients) and validated with test data in the remaining 50% of the dataset. In addition, Denver and Memphis model variables were re-validated and compared to our new model. RESULTS A total of 885,100 pediatric patients were identified in the NTDB to have experienced blunt pediatric trauma, with 1,998 (0.2%) having a diagnosis of BCVI. Skull fractures (OR 1.004, 95% CI 1.003-1.004), extremity fractures (OR 1.001, 95% 1.0006-1.002), and vertebral injuries (OR 1.004, 95% CI 1.003-1.004) were associated with increased risk for BCVI. The BCVI prediction model identified 94.4% of BCVI patients and 76.1% of non-BCVI patients within the NTDB. This study identified ICD9/ICD10 codes with strong association to BCVI. The Denver and Memphis criteria were re-applied to NTDB data to compare validity and only correctly identified 13.4% of total BCVI patients and 99.1% of non BCVI patients. CONCLUSION The prediction model developed in this study is able to better identify pediatric patients who should be screened with further imaging to identify BCVI. LEVEL OF EVIDENCE Retrospective diagnostic study-level III evidence.
