Are severity and location of facial trauma risk factors for cervical spine injuries? 10-year analysis based on the use of the AO spine injury classification and the comprehensive facial injury (CFI) score.

PURPOSE: This study aims to demonstrate a correlation between cervical spine injury and location and severity of facial trauma. METHODS: We did a 10-year retrospective analysis of prospectively collected patients with at least one facial and/or cervical spine injury. We classified facial injuries using the Comprehensive Facial Injury (CFI) score, and stratified patients into mild (CFI < 4), moderate (4 ≤ CFI < 10) and severe facial trauma (CFI ≥ 10). The primary outcome was to recognize the severity and topography of the facial trauma which predict the probability of associated cervical spine injuries. RESULTS: We included 1197 patients: 78% with facial injuries, 16% with spine injuries and 6% with both. According to the CFI score, 48% of patients sustained a mild facial trauma, 35% a moderate one and 17% a severe one. The midface was involved in 45% of cases, then the upper facial third (13%) and the lower one (10%). The multivariate analysis showed multiple independent risk factors for associated facial and cervical spine injuries, among them an injury of the middle facial third (OR 1.11 p 0.004) and the facial trauma severity, having every increasing point of CFI score a 6% increasing risk (OR 1.06 p 0.004). CONCLUSIONS: Facial trauma is a risk factor for a concomitant cervical spine injury. Among multiple risk factors, severe midfacial trauma is an important red flag. The stratification of facial injuries based on the CFI score through CT-scan images could be a turning point in the management of patients at risk for cervical spine injuries before imaging is available.

Management of non-contiguous upper and lower cervical spine fractures.

PURPOSE: Upper cervical fracture combined with non-contiguous lower cervical fracture are not uncommon but complicated. In order to outline a management principle for the upper cervical fracture combined with non-contiguous lower cervical fracture and assess its clinical characteristics, we retrospectively analyzed 59 cases of patients who underwent surgical treatment for upper cervical fracture combined with non-contiguous lower cervical fracture. METHODS: 59 patients of upper cervical fracture combined with non-contiguous lower cervical fracture were treated by surgery in our hospital. According to the AO Spine classification for cervical fractures, there were 21 cases of type B atlas fractures, nine cases of type C atlas fractures; 15 cases of type B axis fractures, 14 cases of type C axis fractures; 19 cases of type B lower cervical fractures, 40 cases of type C lower cervical fractures. The operation time, intraoperative blood loss, complications, VAS scores, JOA scores, ASIA grades, and radiological evaluation of cervical lordosis and stability were collected and recorded. RESULTS: Our results showed the segments of upper cervical fracture combined with non-contiguous lower cervical fracture are mainly concentrated in the atlas-axis and C6, C7 levels. There were 43 cases (72.88%) of associated injuries, mainly involving head trauma and thoracic injuries. Four patients underwent anterior approach surgery only, 43 patients underwent posterior approach surgery only, and 12 patients underwent combined anterior and posterior approach surgery in one stage. All patients had regular follow up with an average duration of 67.83 ± 11.25 months (range, 39 to 103 months). The VAS scores and JOA scores at 12 months postoperatively and at final follow-up showed significant improvement compared to preoperative scores (P < 0.05). At the final follow-up, ASIA grades had improved by 0 to 2 levels. The cervical lordosis at the final follow-up (24.71°±7.39°) showed no statistically significant difference compared to preoperative measurements (26.89°±13.32°). Surgical complications occurred in 17 patients. No cases of vertebral artery injury, screw loosening, or other internal fixation failures were found at final follow-up. CONCLUSIONS: Upper cervical fracture combined with non-contiguous lower cervical fracture can result in varying extents of cervical spinal cord injury and combined trauma in other parts. Surgical treatment of these injuries can achieve favourable clinical and radiological outcomes in the medium to long term follow-up. More research is still needed to optimize clinical decision-making regarding surgical approach.

Prognostic impact of respiratory dysfunction in elderly patients with cervical spinal cord injury and/or fractures: a multicenter survey.

PURPOSE: To investigate the impact of early post-injury respiratory dysfunction for neurological and ambulatory ability recovery in patients with cervical spinal cord injury (SCI) and/or fractures. METHODS: We included 1,353 elderly patients with SCI and/or fractures from 78 institutions in Japan. Patients who required early tracheostomy and ventilator management and those who developed respiratory complications were included in the respiratory dysfunction group, which was further classified into mild and severe respiratory groups based on respiratory weaning management. Patient characteristics, laboratory data, neurological impairment scale scores, complications at injury, and surgical treatment were evaluated. We performed a propensity score-matched analysis to compare neurological outcomes and mobility between groups. RESULTS: Overall, 104 patients (7.8%) had impaired respiratory function. In propensity score-matched analysis, the respiratory dysfunction group had a lower home discharge and ambulation rates (p = 0.018, p = 0.001, respectively), and higher rate of severe paralysis (p < 0.001) at discharge. At the final follow-up, the respiratory dysfunction group had a lower ambulation rate (p = 0.004) and higher rate of severe paralysis (p < 0.001). Twenty-six patients with severe disability required respiratory management for up to 6 months post-injury and died of respiratory complications. The mild and severe respiratory dysfunction groups had a high percentage of severe paraplegic cases with low ambulatory ability; there was no significant difference between them. The severe respiratory dysfunction group tended to have a poorer prognosis. CONCLUSION: Respiratory dysfunction in elderly patients with SCI and/or cervical fracture in the early post-injury period reflects the severity of the condition and may be a useful prognostic predictor.

Management of cervical fractures in ankylosing spondylitis patients: immediate fixation effort via vertebroplasty with one-staged combined anterior and posterior fixation.

The ankylosed spine is prone to fracture even as a result of minor trauma due to its changed biomechanical properties. Fractures in ankylosing spondylitis (AS) patients are highly unstable and surgical intervention for fixation is warranted. Implant failure rates are high and combined anterior and posterior fixation is required to enhance the fixation outcome. For fusion, anterior interbody fusion or posterior bone graft fusion is often adopted. Here, we introduce a new method which combines vertebroplasty with anterior and posterior approaches to improve pain control, facilitate the long-term fixation outcome and mechanics, and decrease perioperative risks with prompt stabilization, especially in patients with spine curve deformity. Here, we present two AS cases with cervical spine fracture treated with this new method.

Biomechanics considerations in the treatment of double traumatic non-contiguous subaxial cervical lesions.

Double traumatic non-contiguous lesions of the subaxial cervical region are a rare event mostly caused by multiple, simultaneous or rapidly consecutive high-energy-impact traumas. The modality of treatment chosen for these lesions must be related to local lower cervical spine biomechanics. We present the case of a 59 year-old patient who suffered a subaxial cervical spine double fracture-dislocation following a complex-dynamic trauma. Radiological imaging displayed a C4-C5 and C7-T1 fracture-dislocation with cord signal intensity abnormalities. This patient showed a complete neurological deficit (ASIA A; mJOA 0) with a C4 sensory-motor level. He was urgently operated upon through an anterior approach, reduction of both dislocations and positioning of intervertebral cages and anterior plates at C4-C5 and C7-T1. At a 16-month follow-up he displays neurological improvement, moving his upper extremities at the C7-C8 motor level and a T5 sensory level (mJOA 3; Odom's Criteria 3). The check-CT scan at 24-month shows the correct positioning of the stabilization system and a complete bone fusion.Double traumatic lesions of the subaxial cervical spine, when interposed by healthy functional segments can be treated as two single independent lesions in order to allow a better outcome.

Improving stability of atlantoaxial fusion: a biomechanical study.

PURPOSE: The incidence of atlanto-axial injuries is continuously increasing and often requires surgical treatment. Recently, Harati developed a new procedure combining polyaxial transarticular screws with polyaxial atlas massae lateralis screws via a rod system with promising clinical results, yet biomechanical data is lacking. This biomechanical study consequently aims to evaluate the properties of the Harati technique. METHODS: Two groups, each consisting of 7 cervical vertebral segments (C1/2), were formed and provided with a dens axis type 2 fracture according to Alonzo. One group was treated with the Harms and the other with the Harati technique. The specimen was loaded via a lever arm to simulate extension, flexion, lateral flexion and rotation. For statistical analysis, dislocation (°) was measured and compared. RESULTS: For extension and flexion, the Harati technique displayed a mean dislocation of 4.12° ± 2.36° and the Harms technique of 8.48° ± 1.49° (p < 0.01). For lateral flexion, the dislocation was 0.57° ± 0.30° for the Harati and 1.19° ± 0.25° for the Harms group (p < 0.01). The mean dislocation for rotation was 1.09° ± 0.48° for the Harati and 2.10° ± 0.31° for the Harms group (p < 0.01). No implant failure occurred. CONCLUSION: This study found a significant increase in biomechanical stability of the Harati technique when compared to the technique by Harms et al. Consequently, this novel technique can be regarded as a promising alternative for the treatment of atlanto-axial instabilities.

A multicenter study of 1-year mortality and walking capacity after spinal fusion surgery for cervical fracture in elderly patients.

BACKGROUND: The 1-year mortality and functional prognoses of patients who received surgery for cervical trauma in the elderly remains unclear. The aim of this study is to investigate the rates of, and factors associated with mortality and the deterioration in walking capacity occurring 1 year after spinal fusion surgery for cervical fractures in patients 65 years of age or older. METHODS: Three hundred thirteen patients aged 65 years or more with a traumatic cervical fracture who received spinal fusion surgery were enrolled. The patients were divided into a survival group and a mortality group, or a maintained walking capacity group and a deteriorated walking capacity group. We compared patients' backgrounds, trauma, and surgical parameters between the two groups. To identify factors associated with mortality or a deteriorated walking capacity 1 year postoperatively, a multivariate logistic regression analysis was conducted. RESULTS: One year postoperatively, the rate of mortality was 8%. A higher Charlson comorbidity index (CCI) score, a more severe the American Spinal Cord Injury Association impairment scale (AIS), and longer surgical time were identified as independent factors associated with an increase in 1-year mortality. The rate of deterioration in walking capacity between pre-trauma and 1 year postoperatively was 33%. A more severe AIS, lower albumin (Alb) and hemoglobin (Hb) values, and a larger number of fused segments were identified as independent factors associated with the increased risk of deteriorated walking capacity 1 year postoperatively. CONCLUSIONS: The 1-year rate of mortality after spinal fusion surgery for cervical fracture in patients 65 years of age or older was 8%, and its associated factors were a higher CCI score, a more severe AIS, and a longer surgical time. The rate of deterioration in walking capacity was 33%, and its associated factors were a more severe AIS, lower Alb, lower Hb values, and a larger number of fused segments.

Stabbed to the back! A C-clamp technique used to stabilize a C7 sagittal split fracture.

The management of stab wounds to the back is controversial. This case report entails a 17-year-old female that was assaulted from behind and stabbed to the lower cervical region with a knife. The patient reported mild lower limb hypoesthesia. Neuroradiological exams showed a sagittal split fracture of C7, with a contextual split lesion of the spinal cord. The patient underwent surgical intervention for the stabilization of the sagittal split fracture via the C-clamp technique and dura mater plastic. In the current literature, the use of the C-clamp technique for the stabilization of a lower cervical fracture has never been reported.

Emergency surgical management of cervical spine fracture-dislocation with acute paraplegia in COVID-19 (Coronavirus disease 2019)-suspected patient: first experience from a German spine centre.

PURPOSE: We present an organized hospital plan for the management of Coronavirus disease (COVID-19) patients requiring emergency surgical interventions. To introduce a multidisciplinary approach for the management of COVID-19-infected patients and to report the first operated patient in the Corona unit. METHODS: A detailed presentation of the hospital plan for a separate Corona unit with its intensive care unit and operating rooms. Description of the management of the first spine surgery case treated in this unit. RESULTS: The Corona unit showed a practical approach for the management of an emergency cervical spine fracture-dislocation with acute paralysis. The patient is 92-year-old female. The mechanism of injury was a simple fall during the stay in the internal medicine department where the patient was treated in the referring hospital. The patient had no other injuries and was awake and oriented. The patient did not have the clinical symptom of COVID-19, and the test result of COVID-19 done in the referring hospital was not available on admission in our emergency room. Education of the medical staff and organization of the operating theatre facilitated the management of the patient without an increased risk of spreading the infection. CONCLUSIONS: The current COVID-19 pandemic requires an extra-ordinary organization of the medical and surgical care of the patients. It is possible to manage an infected or a potentially infected patient surgically, but a multidisciplinary plan is necessary to protect other patients and the medical staff.

Low energy chronic traumatic spondylolisthesis of the axis.

OBJECTIVE: The aim of this study is to present a unique case of a patient who presented to our Emergency Department with evidence of a chronic traumatic spondylolisthesis of the axis with severe displacement treated with anterior cervical discectomy and fusion (ACDF) of C2-C3 as well as and posterior cervical fusion (PCF) of C1-C3. METHODS: One patient with an untreated traumatic spondylolisthesis of the axis with Levine type II injury pattern and 1.2 cm of anterior subluxation underwent ACDF C2-C3 and PCF C1-C3. RESULTS: The patient recovered well, radiographs demonstrated reduction of the anterior subluxation, and the patient reported a neck disability index (NDI) score of 20 at 6-month follow-up with full neurologic function intact. The patient was then lost to follow-up. CONCLUSION: In this report, we present an alcoholic patient with a history of many falls who presented with a Levine type II traumatic spondylolisthesis of the axis with signs of chronicity seen on magnetic resonance imaging (MRI). We were able to partially reduce the anterior displacement with traction, but needed both anterior and posterior cervical approaches to achieve adequate reduction and stabilization of the injury.

Current Topics in the Management of Acute Traumatic Spinal Cord Injury.

Acute traumatic spinal cord injury (SCI) affects more than 250,000 people in the USA, with approximately 17,000 new cases each year. It continues to be one of the most significant causes of trauma-related morbidity and mortality. Despite the introduction of primary injury prevention education and vehicle safety devices, such as airbags and passive restraint systems, traumatic SCI continues to have a substantial impact on the healthcare system. Over the last three decades, there have been considerable advancements in the management of patients with traumatic SCI. The advent of spinal instrumentation has improved the surgical treatment of spinal fractures and the ability to manage SCI patients with spinal mechanical instability. There has been a concomitant improvement in the nonsurgical care of these patients with particular focus on care delivered in the pre-hospital, emergency room, and intensive care unit (ICU) settings. This article represents an overview of the critical aspects of contemporary traumatic SCI care and notes areas where further research inquiries are needed. We review the pre-hospital management of a patient with an acute SCI, including triage, immobilization, and transportation. Upon arrival to the definitive treatment facility, we review initial evaluation and management steps, including initial neurological assessment, radiographic assessment, cervical collar clearance protocols, and closed reduction of cervical fracture/dislocation injuries. Finally, we review ICU issues including airway, hemodynamic, and pharmacological management, as well as future directions of care.

The Dangers of Spear Tackling: A Case Report of a NEXUS-negative High School Football Player.

BACKGROUND: Although "spear tackling" is known to be a risk factor for cervical spine injury due to axial loading of the neck, and although this technique was officially banned from American football in 1976, football-associated cervical spine injuries continue to be reported. This case highlights the importance of recognizing high-risk mechanisms for cervical spine injury, and specifically the danger of spear tackling among football players at all levels. CASE REPORT: A 16-year-old male high school football player presented to the pediatric emergency department for a neck injury sustained after spear tackling during a football game. He had no neurologic symptoms and met the NEXUS criteria for omitting x-ray evaluation. However, the description of spear tackling as the mechanism of injury led to the ordering of cervical radiographs, which revealed a C5 fracture. The patient was ultimately taken to the operating room for internal fixation, with a final surgical diagnosis of a C5 teardrop fracture. On outpatient follow-up at 1 year, the patient has had no neurologic sequelae. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case serves as a reminder that all evaluations of trauma patients should begin with an attempt to determine, as precisely as possible, the mechanism that was in play at the time of injury. The reassurance provided by a normal physical examination may be misleading. Spear tackling is not an uncommonly encountered cause of injury in American football, despite the practice being prohibited since a rule change in 1976. Continued education and increased awareness of the association of axial load injury with spear tackling may make it possible to avoid missing a potentially devastating cervical spine injury.

What is the added sensitivity of non-lateral cervical spine radiographs in the evaluation of acute cervical spine trauma?

PURPOSE: Plain radiography of the cervical spine is used as a screening test for trauma patients. We evaluated the diagnostic yield of performing anteroposterior (AP), odontoid, and oblique views in addition to the lateral view in the current era when radiographs are performed only on low-risk patients. METHODS: All imaging reports from cervical spine radiography studies on patients aged 18 years and older in the emergency room of a major academic medical center between November 22, 2003, and January 17, 2012, were retrospectively reviewed. For the clinical workflow employed at the time of study acquisition, radiologists prospectively reviewed the lateral projection and subsequently reviewed the entirety of the images obtained. Exam reports and, when necessary, images were reviewed to determine which patients had fractures and on which projection the fractures were identified. RESULTS: Six fractures were detected in 7218 exams. Three of these fractures were identified on the lateral radiograph, and three of these fractures were visualized on the additional projections (two on oblique and one on odontoid views). The yield of the additional projections is one fracture per 9713 radiographic projections (90% confidence interval of one fracture per 1245-47,946 examinations). For two of the patients with fractures identified on the lateral projection, an additional fracture was seen when CT was then performed. CONCLUSIONS: Performing additional radiographs of the cervical spine including AP, odontoid, and bilateral oblique projections in trauma patients with low pretest probability of fracture augments the diagnostic yield of lateral radiographs. Considering the potential for devastating neurological outcomes from missed cervical fractures, addition of AP, odontoid, and oblique projections continues to detect fractures at a low rate.

Unilateral vertebral artery injury in a patient with displaced upper cervical spine fractures: the treatment for one case of vertebral artery embolism.

PURPOSE: To report a novel treatment method for vertebral artery injury. Vertebral artery injuries may be caused during trauma by fracture and excessive motion with subluxation from C2 to C6 in spite of vertebral artery deeply seated and normally well protected inside the transverse foramen. Optimal medical management of the occluded vertebral artery has yet to be determined. METHODS: We report on a severely displaced C2-C3 fracture that was found to have a vertebral artery injury. Medical records and imaging were reviewed. RESULTS: A 50-year-old lady was hit by steel tube without loss of consciousness, but complaining of severe cervical and bilateral periscapular pain. Physical examination identified a neurologically intact patient with frontotemporal ecchymosis and posterior cervical tenderness. MRA and DSA showed an occluded left vertebral artery. After 3 days of observation, the patient showed no symptoms of brain ischemia or abnormal sensation and motor at four limbs. To ensure safety, we took the left vertebral artery embolism at the C2 and C5 levels before operation. CONCLUSIONS: To our knowledge, this is the first report of a displaced C2-C3 fracture in which transcatheter unilateral VAI embolization was used to prevent VAI bleeding during operation.

Cervical Myelopathy in a Child: A Rare Cause of Hypoventilation Syndrome Presenting with Type 2 Respiratory Failure.

Hypoventilation syndrome leading to Type 2 respiratory failure is not a rare cause of Pediatric Intensive Care Unit admission and mechanical ventilation. Common causes in pediatric population are Guillain-Barre syndrome and various central nervous system disorders such as encephalitis, traumatic brain injury, and drugs. Any injury or disease in the cervical cord can also produce respiratory paralysis causing respiratory failure. Here, we present two cases of mixed cerebral palsy with cervical myelopathy due to compression effect of fractured segments of first and second cervical vertebrae. Both of them presented with Type 2 respiratory failure.

The performance of rigid scopes for tracheal intubation: a randomised, controlled trial in patients with a simulated difficult airway.

We compared the Bonfils™ and SensaScope™ rigid fibreoptic scopes in 200 patients with a simulated difficult airway randomised to one of the two devices. A cervical collar inhibited neck movement and reduced mouth opening to a mean (SD) of 23 (3) mm. The primary outcome parameter was overall success of tracheal intubation; secondary outcomes included first-attempt success, intubation times, difficulty of intubation, fibreoptic view and side-effects. The mean (95% CI) overall success rate was 88 (80-94)% for the Bonfils and 89 (81-94)% for the SensaScope (p = 0.83). First-attempt intubation success rates were 63 (53-72)% for the Bonfils and 72 (62-81)% for the SensaScope (p = 0.17). Median (IQR [range]) intubation time was significantly shorter with the SensaScope (34 (20-84 [5-240]) s vs. 45 (25-134 [12-230]) s), and fibreoptic view was significantly better with the SensaScope (full view of the glottis in 79% with the SensaScope vs. 61% with the Bonfils). This might be explained by its steerable tip and the S-formed shape, contributing to better manoeuvrability. There were no differences in the difficulty of intubation or side-effects.

SURGICAL CORRECTION OF A CERVICAL SPINAL FRACTURE IN A BENNETT'S WALLABY (MACROPUS RUFOGRISEUS).

Macropods are susceptible to trauma, and fractures of the cervical vertebrae due to collisions are relatively common. A 4-yr-old, intact male Bennett's wallaby (Macropus rufogriseus) was presented acutely nonambulatory and tetraparetic but with motor function present in all limbs. Cervical radiographs revealed a C4 vertebral fracture. Surgical stabilization was obtained through a ventral midline approach whereby the vertebral bodies were distracted and then secured with screws and polymethylmethacrylate (PMMA). Postoperative radiographs revealed restoration of the spinal canal and appropriate implant placement. The patient was discharged 4 days postoperatively and gradually recovered full neurologic function per the owner over the ensuing 10 wk. Subsequent radiographs obtained 10.5 mo postoperatively revealed a healed fracture with stable implants. The ventral spinal distraction and stabilization technique using screws and PMMA, as are used in the domestic dog, was successful in this wallaby despite its smaller vertebral size and comparable lack of soft-tissue support.

Severe Transient Pharyngeal Paralysis Following C2 Fracture Repair.

OBJECTIVES: We report a case of isolated pharyngeal plexus injury following posterior plating of a C2 fracture in an 84-year-old white male. METHODS: Methods include a case report with literature review. RESULTS: The patient presented with dense pharyngeal paralysis and inability to initiate swallowing but maintained true vocal cord movement. The patient required gastrostomy tube feeding for 3 months but eventually recovered his swallowing function. Prior literature on acute pharyngeal paralysis following upper cervical spine fracture repairs is reviewed with recommendations for care of this unique patient population. CONCLUSIONS: Traumatic C2 fracture repair can lead to isolated dense pharyngeal paralysis due to pharyngeal plexus injury with subsequent severe dysphagia. Observation may be appropriate in this population, with consideration of tracheotomy for recurrent aspiration.

Demographics in the context of health-care delivery for C1 and C2 fractures.

Introduction: Atlas and axis fractures are the most severe cervical fractures which may result in complete paralysis or death. The purpose of the current study is to identify disparities regarding length of stay (LOS), mortality, and demographic factors in patients with the most serious cervical spine fractures utilizing a nationally representative database. Materials and Methods: The Nationwide Emergency Department Sample was utilized to provide a representative sample for patients with a primary diagnosis of C1 or C2 fracture presenting to emergency departments in years from October 2015 to December 2019. A multivariable logistic regression model was used to estimate LOS for different patient demographics, including gender, race, and age. Results: A weighted sample of 7,262,791 patients presented to emergency rooms in the United States between 2015 and 2019. The mean age at admission was 76 years old, 52.6% of patients were female, and 83.0% identified as white. Patients between 45 and 65 and patients over 65 were significantly more likely to have an increased LOS. Women were less likely to have an increased LOS than men. Patients identifying as Black were significantly more likely to have increased LOS over white patients. In addition, patients who had an increased LOS were more likely to die in the hospital than patients with a shorter LOS. Conclusion: This study provides patient characteristics that help providers determine patient risk factors for increased hospital LOS and in-hospital mortality for those suffering from C1 and C2 fractures. Clinicians should be made aware of these disparities to allow equitable delivery of care.

Coil Embolization for Asymptomatic Low-grade Vertebral Artery Injury which Worsened after Cervical Decompression Surgery: A Case Report.

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.
