Study Design: Retrospective radiological study. Purpose: We aimed to determine the prevalence of ponticulus posticus (PP) and high-riding vertebral artery (HRVA) occurring simultaneously on the same side (PP+HRVA) and in cases of PP+HRVA, to assess C2 radio-anatomical measurements for C2 pars length, pedicle width, and laminar thickness. Overview of Literature: PP and HRVA predispose individuals to vertebral artery injuries during atlantoaxial fixation...

BACKGROUND: Multilevel anterior cervical decompression and fixation of four and more levels is a common surgical procedure used for several diseases. METHODS: We reviewed the radiological and clinical outcomes after anterior cervical discectomy or corpectomy and fixation of four and more levels in 85 patients (55 men and 30 women) with an average age of 59.6 years. Surgical indication was multilevel cervical degenerative myelopathy and radiculopathy in 72 (85%) patients, multilevel cervical spondylodiscitis in four (5%), complex traumatic cervical fractures in four (5%), metastatic cervical spine tumor in two (2%), and ossification of the posterior longitudinal ligament in three (3%) patients...

PURPOSE: This study aimed to evaluate the impact of several factors, including patients' intraoperative position, intraoperative visualization technique, fixation method, and type of screws and their parameters, on the frequency of intraoperative screw-associated complications in posterior transarticular C1-C2 fixation. METHODS: A systematic review of the PubMed database between January 1986 and March 2018 was performed. The key inclusion criteria comprised detailed descriptions of the surgical technique and post-operative screw-associated complications...

Object: Surgical clipping of paraclinoid aneurysm, thrombosed large aneurysm, and/or vertebral-basilar dissecting aneurysms can be very difficult and has relatively high morbidity. We describe our experience using skull base and bypass technique and discuss the advantages and its pitfalls. Patients and Methods: We retrospectively reviewed medical charts of 22 consecutive patients with complex aneurysmal lesions underwent skull base and/or bypass techniques between March 2012 and April 2017...

To evaluate and compare the clinical and radiographic results between temporary C1-C2 pedicle screw fixation and cable-dragged reduction and cantilever beam internal fixation. Between 2010 and 2013, temporary C1-C2 pedicle screw fixation (Group P, 28 patients) and cable-dragged reduction following cantilever beam internal fixation (Group C, 33 patients) were performed on type II odontoid fracture cases. Implants were removed after fracture union. All of the 61 surgeries were performed successfully with no iatrogenic neurological worsen...

Introduction: Vertebro-basilar thrombosis is often lethal. We report a post-traumatic case in which logistical issues were overcome to secure prompt endovascular intervention resulting in a favourable outcome. Case presentation: We report this case to highlight (i) the need, across the United Kingdom, for rapid access to 24/7 neurointerventional services and (ii) the fact that vertebral artery injury during C-spine trauma, while not uncommon, can rarely have catastrophic complications...

OBJECTIVE: To review the literature related to iatrogenic lumbar artery injury (ILAI) in spine surgery with a focus on which iatrogenic operation may cause lumbar artery (LA) injury. METHODS: We conducted a comprehensive search in the Web of Science, PubMed, EMBASE and Chinese biomedical databases in July 2018. RESULTS: A total of 20 articles on ILAI were selected in this study, most of which were published as case reports involving a total of 26 cases...

Stroke-associated ocular disorders are vision-threatening. This study was designed to evaluate in vivo retinal injury induced by transient global cerebral ischemia/reperfusion (I/R). A stroke-induced retinal injury model in Wistar rats was established by electrocoagulation of bilateral vertebral arteries, combined with transient ligation of the bilateral common carotid arteries. Rats were randomly divided into groups based on the time post cerebral perfusion (3 h, 24 h, 48 h, 72 h, and 7 days). Retinal injury was evaluated by histological analysis, examination of eye fundus, and TUNEL staining...

Blunt cerebrovascular injury (BCVI) is a non-penetrating injury to the carotid and/or vertebral artery that may cause stroke in trauma patients. Historically BCVI has been considered rare but more recent publications indicate an overall incidence of 1-2% in the in-hospital trauma population and as high as 9% in patients with severe head injury. The indications for screening, treatment and follow-up of these patients have been controversial for years with few clear recommendations. In an attempt to provide a clinically oriented guideline for the handling of BCVI patients a working committee was created...

BACKGROUND: The Magerl and Goel-Harms techniques have been reported to produce excellent treatment outcomes in cases of atlantoaxial subluxation, but they also carry a risk of vertebral artery injuries. In order to completely prevent such injuries, we developed a surgical procedure, involving bone grafting between the C1 posterior arch and C2 lamina with clamp- or hook-and-rod-based fixation combined with the insertion of an interference screw into the posterior atlantoaxial joint. METHODS: This was a retrospective single-center study...

INTRODUCTION: The endovascular treatment of intracranial atherosclerotic stenosis has become a common intervention. However, few reports are available regarding stenting performed for hypoplastic vertebral artery (HVA) with multiple atherosclerotic lesions. Combining multiple neuroendovascular devices provides more possibilities for technical success. We describe a stenting technique using a distal intracranial catheter (Navien) for providing an approach to an HVA with multiple existing atherosclerotic lesions...

Background: Preoperative assessment of C2 pedicle morphology is critical to safe pedicle screw placement. To avoid iatrogenic injury, complex digital templating software has been introduced; however, this technology may not be available in many centers. We report a technique for preoperative assessment of C2 pedicle screw placement safety based upon 2-dimensional sagittal computed tomography (CT) scan images and verify its utility in clinical practice. Methods: A total of 46 consecutive patients underwent cervical spine CT scans between 2005 and 2011...

We describe a rare case of a 69-year-old male who developed a hemorrhagic transformation of a posterior fossa ischemia after the initiation of antithrombotic therapy for the management of blunt vertebral artery injury (BVAI). To the best of our knowledge, this is the first reported case in the literature so far. Thus, we present our diagnostic approach, its associated treatment challenges, and its overall outcome.

BACKGROUND: Cervical arterial dissection, can occur spontaneously and is a rare but catastrophic adverse event associated with neck manipulation. Pathophysiology involves altered integrity of the arterial wall increasing its vulnerability to minor trauma. Those at risk are difficult to detect. Previous screening investigated blood flow but altered mechanical properties as stiffness of cervical arterial wall could provide a more valid indication of arterial integrity or even early dissection...

STUDY DESIGN: A biomechanical in vitro study using human cadaveric spines. OBJECTIVE: To compare atlantoaxial stability and stiffness of a C1 lateral mass - C2 short pedicle - C3 lateral mass screw-rod construct versus C1 lateral mass - C2 pedicle screw-rod construct. SUMMARY OF BACKGROUND DATA: The C1 lateral mass - C2 pedicle screw-rod construct provides excellent atlantoaxial fixation but C2 pedicle screw placement is associated with risk of vertebral artery injury...
