The authors present a retrospective analysis of their experience in the treatment vertebral artery (VA) dissecting aneurysms and propose management strategy for such aneurysms, with special emphasis on most formidable VA which involve origin posterior inferior cerebellar (PICA).Since 1998, 18 patients 11 whom presented subarachnoid hemorrhage (SAH), have been treated by endovascular surgery at authors' institution. Obliteration entire segment dissected site coils (internal trapping) was...
The general method of analysis for resonant power converters is presented. This analytical generalizes the idea state-space-averaging technique to overcome limitations conventional method. As result, characteristics are clarified so that transfer functions and stability conditions revealed. In addition, a computer program based on proposed developed. can be applied various converters, even when they have parasitic losses higher-order circuits.< <ETX...
Background Dual antiplatelet therapy (DAPT) is necessary to prevent thromboembolic complications after stent-assisted coiling (SAC) or flow-diversion (FD) for cerebral aneurysms, but the optimal regimen remains unclear. Objective To determine DAPT duration in patients with SAC/FD. Methods This multicenter cohort study enrolled who received SAC/FD aneurysms at seven Japanese institutions between January 2010 and December 2020. The primary outcome was time from procedure occurrence of a...
Object. To elucidate an optimal management strategy for unruptured paraclinoid aneurysms, the authors retrospectively reviewed their experience in treatment of 100 patients who underwent 112 procedures 111 aneurysms performed using direct surgery and/or endovascular treatment. Methods. Between 1997 and 2002, categorized according to a modified al-Rodhan classification (Group Ia, 30 anterior wall lesions; Group Ib, 25 ventral II, 18 true ophthalmic artery III, 37 carotid cave IV, one...
Hepatic encephalopathy is one of the major complications in decompensated liver cirrhosis. The current study was conducted to clarify mechanisms zinc deficiency cirrhosis and its involvement hepatic via ammonia metabolism. Ten patients each with compensated or 11 healthy volunteers were enrolled study. Serum levels daily urinary excretion measured, an oral zinc-tolerance test performed examine malabsorption, effects diuretics on supplementation metabolism skeletal muscle studied. mean serum...
Background The dual-layer nitinol CASPER stent was designed to prevent plaque prolapse into its strut and periprocedural stroke. Objective To conduct a clinical trial for government approval of the device in patients at either high or normal risk carotid endarterectomy (CEA). Methods Eligible had ≥50% symptomatic stenosis ≥80% asymptomatic according North American Symptomatic Carotid Endarterectomy Trial methods (peak systolic velocity 130 230 cm/s on ultrasonography, respectively). primary...
We compared the physicochemical and spectroscopic properties of humic acids obtained from charred residue Miscanthus sinensis Anderss A horizons volcanic ash soils in Japan. The elementary composition, Δlog K RF values, UV, visible, IR absorption spectra, x-ray diffraction pattern are similar to those soils. findings indicate that deserves attention as a possible source with high degree darkening
Neuroendovascular therapy is a key treatment for cerebrovascular disorders, driven by advancements in devices and techniques. The Japanese Society Therapy (JSNET) established certification system 1997 to ensure operator competence minimize complications, with the first examination 2002. JSNET offers 2 main certifications: specialist instructor. Specialists perform basic procedures, while instructors lead practice, education, research. In 2020, mechanical thrombectomy practitioner...
✓ Polyarteritis nodosa (PAN) is a rare systemic necrotizing arteritis that involves small- and medium-sized arteries in various organs. Although aneurysm formation visceral typical finding PAN, intracranial aneurysms are much less common, only few cases of rupture associated with this disease have been documented. In paper, the authors report on ruptured PAN anterior cerebral artery; lesion was trapped resected. On histological examination, extensive fibrinoid necrosis an inflammatory...
Background It has been recognized that spontaneous vertebral artery dissection without neurological symptoms is not rare and easily misdiagnosed. Clinical clue for diagnosis of includes initial such as headache, neck pain, or dizziness. Aim To assess the role dissection. Methods Between September 2007 January 2014, we retrospectively reviewed clinical records 83 patients with unilateral consciousness disturbance at admission. Based on diagnostic criteria Spontaneous Cervicocephalic Arterial...
Object Indocyanine green (ICG) videography is commonly used in the neurosurgical field for minimally invasive neurosurgery. The aim of this study was to evaluate a new intraoperative imaging modality by performing transdural ICG during surgery meningiomas. Methods Between March 2011 and April 2012, 10 patients with meningiomas received intravenous injection 12.5 mg just prior dural opening. cases comprised 8 convexity 2 foramen magnum Efficacy assessed terms tumor volume, circulation time...
Japan is a typical volcanic country. Volcanic ash soils which develop in deposits of are widely distributed Japan. Studies have shown that an important feature humus the A horizons predominance Type humic acids with high degree humification (1, 2). The formation may proceed mediation soil enzymes and inorganic components, since they capable accelerating conversion phenolic compounds to polymers darkening (3–5). As another possible mode, authors suggested charring process plants might...
A 19-month-old child was gradually suffering from gait disturbance and referred by his pediatrician to the authors' institution. Spinal MRI showed Gd-enhanced spinal cord tumor congestive myelopathy. Intraoperatively lesion seen be a hemangioblastoma. Because discrimination of arterialized draining veins feeding arteries difficult, indocyanine green videography conducted differentiate them. Real-time evaluation FLOW 800 revealed that slope average signal intensity in artery steeper than...
