OBJECTIVE This study aimed to quantify the cerebral blood flow (CBF) after bilateral, transcranial near-infrared light-emitting diode (LED) irradiation to the forehead in a patient in a persistent vegetative state following severe head injury. BACKGROUND DATA Positive behavioral improvement has been observed following transcranial near-infrared light(More)
The present study investigated the appropriate conditions for induction of lesions in the rabbit atherosclerosis model. Four-week-old male Japanese white rabbits (n = 19) were fed the high cholesterol diet (HCD). This group was classified as the early start (ES) group. The animals were divided into three groups: (i) 1% HCD group (n = 8), (ii) 2% HCD group(More)
We treated three patients with tandem internal carotid stenoses in single procedures including carotid endarterectomy (CEA) for the proximal stenosis and percutaneous transluminal angioplasty (PTA) for the distal stenosis. We devised a Y-shaped shunt tube for the CEA, through which a balloon catheter was introduced to perform PTA guided by mobile digital(More)
PURPOSE Preventing cerebral embolism from debris produced during carotid artery stenting (CAS) is important. This study compared the treatment outcomes of CAS using two types of filter-based embolic protection devices currently in use in Japan. MATERIALS AND METHODS We assessed 121 consecutive cases of CAS performed with FilterWire EZ™ between July 2010(More)
BACKGROUND Intracranial vascular anomalies involving the middle cerebral artery (MCA) are relatively rare, as such knowledge will be helpful for planning the optimal surgical procedures. CASE DESCRIPTION We herein present the first case of a ruptured internal carotid artery aneurysm arising at the origin of the hypoplastic duplicated MCA associated with(More)
RATIONALE AND OBJECTIVES Endovascular treatments such as balloon angioplasty and injection of vasodilators play an important role in cerebral vasospasm refractory to first-line therapies. Experimental studies with intracranial arteries of animals have some limitations, however, because in most cases endovascular devices are too large and inflexible to(More)
Dear Sir, Non-bifurcating cervical carotid artery is a rare anatomical variation of the carotid artery in which the branches of the external carotid artery (ECA) directly arise from the common carotid artery without forming a bifurcation [1, 2]. In addition, cases of congenital EC–internal carotid artery (ICA) anastomosis at the cervical segment forming a(More)
BACKGROUND Stent-assisted coil embolization is effective for intracranial aneurysms, especially wide-necked aneurysms; however, the optimal antiplatelet regimens for ischemic events that develop after coil embolization have not yet been established. We aimed to determine the onset time of such postoperative ischemic events and the relationship between these(More)
BACKGROUND Venous hypertension is regarded as an important factor in the pathogenesis of dural arteriovenous fistula (DAVF). We investigate histologic reaction of dural sinus under the condition of venous hypertension using a rat venous hypertension model to present hemodynamic and immunohistochemical effect in the development of DAVF. METHODS Twenty-four(More)
Background: No predictor of postoperative ischemic events has been identified in patients undergoing carotid artery stenting. We aimed to determine whether N ε -(carboxymethyl)lysine in debris trapped by an embolic protection filter device is a predictor of postoperative ischemic events. Methods: We enrolled 27 patients (73.4 ± 7.2 years; 22 male, 5 female)(More)
