STUDY DESIGN Retrospective study. OBJECTIVE The purpose of this study was to analyze the relationship of the parameters of cervical sagittal alignment between those obtained from cervical CT and those obtained from radiography, as well as to determine which parameter would help predict physiological lordosis of the cervical spine. SUMMARY OF BACKGROUND(More)
Transplantation of adipose-derived stem cells (ASCs) is one of the possible therapeutic tools for ischemic damage. In this study, we observed the effects of ASCs against ischemic damage in the ventral horn of L(5-6) levels in the rabbit spinal cord. ASCs were isolated from rabbits, and cell type was confirmed by flow cytometry analysis, labeling with CM-DiI(More)
STUDY DESIGN Retrospective analysis. OBJECTIVE The main objectives of this study were to analyze and compare cervical sagittal parameters, including the T1 slope, in a population of 45 patients with degenerative cervical spondylolisthesis (DCS) and to compare these patients with a control group of asymptomatic population. SUMMARY OF BACKGROUND DATA(More)
OBJECTIVE Endovascular treatment of wide-necked intracranial aneurysms is a challenge and the durability and the safety of these treated aneurysms remain unknown. The aim of this study was to evaluate the clinical and long-term angiographic results of wide-necked intracranial aneurysms treated with coil embolization. METHODS Between January 2002 and(More)
OBJECTIVE To measure the orientation of the facet joints of cervical spine (C-spine) segments in the sagittal plane, known as the pedicle-facet (P-F) angle, and to use these measurements to evaluate the relationship between the P-F angle and the amount of vertebral anterolisthesis in patients with degenerative cervical spondylolisthesis (DCS). METHODS A(More)
Contrast-induced encephalopathy after cerebral angiography is a rare complication and until now, only few cases have been reported. This paper reports on contras-induced encephalopathy mimicking meningoencephalitis after cerebral angiography by using iodixanol, an iso-osmolar non-ionic contrast agent. A 58-year-old woman underwent cerebral angiography for(More)
BACKGROUND The fate and safety of thrombus remnant despite intra-arterial thrombolysis for unexpected thrombus formation has rarely been reported. METHODS From January 2010 to May 2015, 131 consecutive patients with ruptured intracranial aneurysms were treated by endovascular methods at our institution. Among the 21 patients (16%) treated by(More)
OBJECTIVE To investigate the effect of different pillow heights on the slope of the cervicothoracic spine segments. METHODS A prospective analysis of data from 16 asymptomatic adults (aged 20 to 30 years) was carried out. Exclusion criteria were history of injury or accident to the cervicothoracic spine, cervicothoracic spine surgery, or treatment for(More)
OBJECTIVE To examine the safety and efficacy of mechanical thrombectomy using a retrievable stent for thromboembolic occlusion occurring during coil embolization of ruptured intracranial aneurysms. METHODS Between June 2011 and June 2015, 631 consecutive patients with ruptured intracranial aneurysms underwent coil embolization at 6 hospitals. Among 53(More)
OBJECTIVE Therapeutic hypothermia (TH) and decompressive craniectomy are neuroprotective interventions following severe brain swelling. The precise benefits, risks, and clinical outcomes in brain swelling after TH are still being investigated. We aimed to investigate the effects of TH in severe brain injury after decompressive craniectomy. METHODS We(More)
