BACKGROUND: Blunt cerebrovascular injury (BCVI) was underdiagnosed until the 1990s when blunt carotid injuries were found to be more common than historically described. Technological advancements and regionalization of trauma care have resulted in increased screening and improved diagnosis of BCVI. The aim of this study was to demonstrate that systematic evaluation of the screening and diagnosis of BCVI, combined with early and aggressive treatment, have led to reductions in BCVI-related stroke and mortality...

BACKGROUND AND PURPOSE: Stroke-prone spontaneously hypertensive rats (SHR-A3) develop strokes and progressive kidney disease as a result of naturally occurring genetic variations. We recently identified genetic variants in immune signaling pathways that contribute to end-organ injury. The present study was designed to test the hypothesis that a dysregulated immune response promotes stroke susceptibility. METHODS: 20-week old male SHR-A3 rats were salt loaded and treated with the immunosuppressant mycophenolate mofetil (MMF, 25 mg/kg/day, p...

RATIONALE AND OBJECTIVES: Blunt cerebrovascular injury (BCVI) is uncommon, but delayed detection can have disastrous consequences. The Denver criteria are the most commonly used screening criteria. We aim to examine the utilization of screening criteria in the emergency department (ED) of our institution and assess whether patients with risk factors were imaged. MATERIALS AND METHODS: A survey questionnaire was sent out to radiologists in a large academic institution...

REVIEW
Curtis Edward Offiah, Emily Day
: Imaging of the blunt traumatic injuries to the craniocervical junction can be challenging but central to improving morbidity and mortality related to such injury. The radiologist has a significant part to play in the appropriate management of patients who have suffered injury to this vital junction between the cranium and the spine. Knowledge of the embryology and normal anatomy as well as normal variant appearances avoids inappropriate investigations in these trauma patients. Osseous injury can be subtle while representing important radiological red flags for significant underlying ligamentous injury...

Study Design Retrospective comparative study. Objective To compare strict Biffl criteria to more-liberal criteria for computed tomography angiography (CTA) when screening for blunt cerebrovascular injury (BCVI). Methods All CTAs performed for blunt injury between 2009 and 2011 at our institution were reviewed. All patients with cervical spine fractures who were evaluated with CTA were included; patients with penetrating trauma and atraumatic reasons for imaging were excluded. We then categorized the patients' fractures based on the indications for CTA as either within or outside Biffl criteria...

OBJECTIVE Blunt traumatic cerebrovascular injury (TCVI) represents structural injury to a vessel due to high-energy trauma. The Biffl Scale is a widely accepted grading scheme for these injuries that was developed using digital subtraction angiography. In recent years, screening CT angiography (CTA) has been used to identify patients with TCVI. The reliability of this scale, with injuries assessed using CTA, has not yet been determined. METHODS Seven independent raters, including 2 neurosurgeons, 2 neuroradiologists, 2 neurosurgical residents, and 1 neurosurgical vascular fellow, independently reviewed each presenting CTA of the neck performed in 40 patients with confirmed TCVI and assigned a Biffl grade...

BACKGROUND: We implemented expanded screening criteria for blunt cerebrovascular injuries (BCVIs) in an attempt to capture the remaining 20% of patients not historically identified with earlier protocols. We hypothesized that these expanded criteria would capture the additional 20% of BCVI patients not previously identified. METHODS: Screening criteria for BCVI were expanded in 2011 after identifying new injury patterns. The study population included 4 years prior (2007 to 2010; classic) and following (2011 to 2014; expanded) implementation of expanded criteria...

BACKGROUND: The short-term natural history of blunt cerebrovascular injuries (BCVI) has been previously described in the literature, but the purpose of this study is to analyze long-term serial follow-up and lesion progression of BCVI. METHODS: This is a single institution's retrospective review of a prospectively collected database over four years (2009-2013). All patients diagnosed with BCVI by CT scan were identified and injuries graded based on modified Denver scale...

PURPOSE OF REVIEW: Athletic neurosurgical emergencies are injuries that can lead to mortality or significant morbidity and require immediate recognition and treatment. This review article discusses the epidemiology of sports-related traumatic brain injury (TBI) with an attempt to quantify the incidence of neurosurgical emergencies in sports. Emergencies such as intracranial hemorrhage, second impact syndrome, vascular injuries, and seizures are discussed. RECENT FINDINGS: The incidence of sports-related TBI presenting to level I or II trauma centers in the USA is about 10 in 100,000 population per year...

BACKGROUND: Severe traumatic brain injury (TBI) may increase the risk of venous thromboembolic complications; however, early prevention with heparinoids is often withheld for its anticoagulant effect. New evidence suggests low molecular weight heparin reduces cerebral edema and improves neurological recovery after stroke and TBI, through blunting of cerebral leukocyte (LEU) recruitment. It remains unknown if unfractionated heparin (UFH) similarly affects brain inflammation and neurological recovery post-TBI...

OBJECTIVE Blunt cerebrovascular injuries (BCVIs) affect approximately 1% of patients with blunt trauma. An antithrombotic or anticoagulation therapy is recommended to prevent the occurrence or recurrence of neurovascular events. This treatment has to be carefully considered after severe traumatic brain injury (TBI), due to the risk of intracranial hemorrhage expansion. Thus, the physician in charge of the patient is confronted with a hemorrhagic and ischemic risk. The main objective of this study was to determine the incidence of BCVI after severe TBI...

BACKGROUND: Pediatric blunt cerebrovascular injury (BCVI) lacks accepted treatment algorithms, and postinjury outcomes are ill defined. OBJECTIVE: To compare treatment practices among pediatric trauma centers and to describe outcomes for available treatment modalities. METHODS: Clinical and radiographic data were collected from a patient cohort with BCVI between 2003 and 2013 at 4 academic pediatric trauma centers. RESULTS: Among 645 pediatric patients evaluated with computed tomography angiography for BCVI, 57 vascular injuries (82% carotid artery, 18% vertebral artery) were diagnosed in 52 patients...

Risk factors for blunt cerebrovascular injury (BCVI) may differ between children and adults, suggesting that children at low risk for BCVI after trauma receive unnecessary computed tomography angiography (CTA) and high-dose radiation. We previously developed a score for predicting pediatric BCVI based on retrospective cohort analysis. Our objective is to externally validate this prediction score with a retrospective multi-institutional cohort. We included patients who underwent CTA for traumatic cranial injury at four pediatric Level I trauma centers...

OBJECTIVE Blunt cerebrovascular injury (BCVI) occurs in approximately 1% of the blunt trauma population and may lead to stroke and death. Early vascular imaging in asymptomatic patients at high risk of having BCVI may lead to earlier diagnosis and possible stroke prevention. The objective of this study was to determine if the implementation of a formalized asymptomatic BCVI screening protocol with CT angiography (CTA) would lead to improved BCVI detection and stroke prevention. METHODS Patients with vascular imaging studies were identified from a prospective trauma registry at a single Level 1 trauma center between 2002 and 2008...

BACKGROUND: Early antithrombotic therapy (AT) is the mainstay of treatment in the management of blunt cerebrovascular injury (BCVI). Despite this, optimal timing of initiation of AT in patients with BCVI in the presence of concomitant traumatic brain injury (TBI) or solid organ injury (SOI) remains controversial. The purpose of this study was to evaluate the impact of early initiation of AT on outcomes in patients with BCVI and TBI and/or SOI. METHODS: Patients with BCVI and concomitant TBI and/or SOI over 6 years were identified...
