Assessment of the difference in posterior circulation involvement between pediatric and adult patients with moyamoya disease.
OBJECT There is no description of the change in the posterior cerebral artery (PCA) in the diagnostic criteria of moyamoya disease (MMD). However, PCAs are often involved in the clinical setting, and… Expand
Persistent primitive trigeminal artery-cavernous sinus fistula with intracerebral hemorrhage: endovascular treatment using detachable coils in a transarterial double-catheter technique. Case report…
Intracerebral hemorrhage occurred in this 61-year-old woman with preexisting diplopia and proptosis. Results of angiography demonstrated a persistent primitive trigeminal artery (PPTA)-cavernous… Expand
Differential diagnosis of the infundibular dilation and aneurysm of internal carotid artery: assessment with fusion imaging of 3D MR cisternography/angiography.
Fusion imaging of 3D MR cisternography/angiography was used for the assessment of the vascular bulging finding detected by MR angiography from the viewpoint of the outer wall configuration of the… Expand
EFFECTS OF DEFEROXAMINE‐ACTIVATED HYPOXIA‐INDUCIBLE FACTOR‐1 ON THE BRAINSTEM AFTER SUBARACHNOID HEMORRHAGE IN RATS

OBJECTIVEHypoxia-inducible factor (HIF)-1 is a transcription factor that regulates the expression of various neuroprotective genes. The goal of this study was to clarify the relationship between… Expand
Transient memory disturbance after removal of an intraventricular trigonal meningioma by a parieto-occipital interhemispheric precuneus approach: Case report.
BACKGROUND Pitfalls in a parieto-occipital interhemispheric precuneus approach for the ventricular trigonal region of a dominant hemisphere have been rarely reported. We described a case with memory… Expand

Risk of rupture of unruptured cerebral aneurysms in elderly patients
Objectives: The aim of this study was to identify risk factors for rupture of unruptured cerebral aneurysms (UCAs) in elderly Japanese patients aged 70 years or older. Methods: The participants… Expand
Computational Fluid Dynamics of Carotid Arteries After Carotid Endarterectomy or Carotid Artery Stenting Based on Postoperative Patient-Specific Computed Tomography Angiography and Ultrasound Flow…
BACKGROUND:There are significant differences in the postoperative morphological and hemodynamic conditions of the carotid arteries between carotid artery stenting (CAS) and endarterectomy (CEA).… Expand
