The incidence and cause of strokes associated with pregnancy the puerperium are still not fully understood. aim this study was to characterize pregnancy-related in Japan using a large-scale survey current imaging techniques.A retrospective analysis conducted based on clinical chart reviews 736 stroke teaching hospitals certified by Stroke Society between 2012 2013, web-based questionnaire requesting detailed course without any personally identifying information. collection rate 70.5%, 151...
The mechanism of motor recovery after stroke may involve reorganization the surviving networks. However, details adaptive changes in structural connectivity are not well understood. Here, we show long-term white matter microstructure that relate to patients. We studied ten subcortical ischemic patients who showed hemiparesis at initial clinical examination and an infarcted lesion centered posterior limb internal capsule unilateral hemisphere diffusion-weighted magnetic resonance imaging...
Introduction During carotid artery stenting (CAS), safe navigation of the guiding catheter (GC) is essential for success procedures. However, in cases where stenosis or floating thrombi are located common (CCA), especially proximal lesions, advancing GC without touching lesions often difficult. We describe a preliminary experience “no-touch” technique navigating to CCA using an inner with specifically designed shape and stiffness optimized overcome tortuous anatomy. Methods retrospectively...
Abstract Background When inserting central venous catheters, inadvertent injury of major vessels is a rare yet critical complication. Direct surgery sometimes overly invasive. This report describes subclavian artery caused by cannulation dialysis catheter, successfully treated with covered stent. Case Presentation An 82‐year‐old woman acute renal failure due to sepsis required emergency dialysis. During the insertion 12‐Fr catheter into right jugular vein, pulsatile reflux was noted....
Myasthenic crisis (MC) represents the most severe and life-threatening complication of myasthenia gravis (MG). Some patients exhibit refractory responses to conventional immunotherapies, including intravenous immunoglobulin plasma exchange. This report describes a patient with MC repetitive high-dose steroids immunoglobulin, requiring ventilator support. Within 2 days eculizumab administration, significant improvement enabled discontinuation. Subsequent doses further ameliorated limb...
OBJECTIVELong-term follow-up results of the treatment unruptured intracranial aneurysms (UIAs) by means coil embolization remain unclear. The aim this study was to analyze frequency rupture, retreatment, stroke, and death in patients with coiled UIAs who were followed for up 20 years at multiple stroke centers.METHODSThe authors retrospectively analyzed data from cases which underwent between 1995 2004 4 centers. In collecting late (≥ 1 year) data, postal questionnaires used assess whether...
To improve the activities of daily living patients with injury to central nervous system, physical therapy starting from acute phase is important. Recently, efficacy using a hybrid assistive limb (HAL) robot suit was reported. However, individual differences exist in effects HAL. We investigated factors predicting HAL 15 at our institution system injury, primarily due stroke, who underwent training during phase. Patients were classified as either "with suitability" or "without based on...
Segmental arterial mediolysis(SAM)is a rare non-inflammatory and non-atherosclerotic arteriopathy associated with the occurrence of multiple aneurysms such as intracranial intraperitoneal aneurysms. We report case hemorrhage that occurred during acute stage subarachnoid hemorrhage(SAH). An 82-year-old woman presented sudden onset loss consciousness diagnosis SAH. Digital subtraction angiography demonstrated two consecutive vertebral artery-posterior inferior cerebellar artery The larger...
Objective Carotid artery stenting for heavily calcified lesions is challenging interventionists. A calcium burden associated with suboptimal dilatation, periprocedural complications, high rates of restenosis, and poor outcomes. We describe the first report 2 cases successful carotid using a scoring balloon. Case Presentation The patients were both aged 75 years, 1 male female, who had experienced ipsilateral stroke prior to procedures. They dense calcifications at lesions, stenosis 95% (near...
Idiopathic intracranial hypertension (IIH) is characterized by an elevated pressure of unknown cause, which can lead to severe and sometimes irreversible visual impairment. Recently, venous sinus stenting (VSS) has emerged as alternative treatment option for IIH. Here, we report two patients with IIH who successfully underwent VSS in the transverse displayed rapid improvement symptoms. Two young women presented progressive symptoms papilledema. The cerebrospinal fluid (CSF) opening pressures...
Reversible cerebral vasospasm syndrome (RCVS) is characterized by multiple reversible convulsions of the arteries, accompanied recurrent, thunderclap-like headaches. The prognosis most patients favorable; however, extensive infarction may result in significant disability or mortality approximately 5% cases. Endovascular treatment be a therapeutic option for who do not respond to medical therapy. However, there paucity detailed studies addressing this procedure. A 33-year-old woman presented...
Two mechanical thrombectomy techniques are proposed for tandem occlusion of the anterior circulation: treating extracranial carotid artery lesion first via an antegrade approach and intracranial a retrograde approach. Previous reports show that has shorter reperfusion time better prognosis, but re-occlusion after recanalization may occur. We describe case with repeated occlusions using discuss possible countermeasures. A 94-year-old woman presented acute cerebral ischemia due to T left...
Objective: A case that suffered vessel perforation during flow diverter stent placement is reported.
要旨：症候性頭蓋内動脈狭窄の再発率は10～18％ / 年と高く，治療抵抗性の疾患である．その病態は多様であり，各病態に対する治療方針はそれぞれ異なる．近年の薬物治療の進歩によって頭蓋内動脈狭窄のイベント率は低下傾向にある．これに対し，血行再建術には現時点で優位性を示すエビデンスはない．頭蓋内動脈狭窄ではmisery perfusion を呈する症例は少なく，EC/IC bypass の適応は限られ，頭蓋内動脈用ステントもその有効性は示されていない．しかし，real world では積極的にこれらの介入が行われていると懸念される．外科治療を行う際には，病態が明確であり，「積極的」薬物治療にも抵抗性の症例のみを対象とすべきで，明確なエビデンスが示されていない現状では，best medical treatment の進歩を十分認識したうえで，血行再建術の適応にはより慎重であるべきと考える．
Background and Purpose: Small vessel infarction after cranial irradiation is rare manifestation, whereas large disease well-known as a late complication. The purpose of this study to investigate the clinical features small associated with previous irradiation. Patients Methods: This retrospective chart review patients presenting irradiation, retrieved from single center database between 1998 2015. We reviewed characteristics, types doses interval first stroke, radiographic findings...
It is now accepted that carotid artery stenosis should be treated as a part of systemic atherothrombosis. However, little known about the association in atherosclerosis between and coronary arteries. We retrospectively investigated plaque vulnerability diagnosed on magnetic resonance imaging (MRI) coexisting patients scheduled for endarterectomy (CEA) or stenting (CAS). Eighty-nine consecutive cases underwent reconstruction at Kyoto University Hospital 2010 2015 were enrolled this study. Ten...
[Background and Purpose] Neuro-interventional radiology (NIVR) is increasingly recognized as an essential option for acute stroke treatment. However, the access to NIVR physician or NIVR-capable hospital still limited. Patient transfer system between primary centers (PSCs) comprehensive has a problem about deterioration during transfer, insufficient information transmission, small area coverage, loss of time. We organized mobile team consisting 6-7 board certified physicians, concluded...
Introduction In carotid artery stenting (CAS), a guiding catheter (GC) placement to the appropriate position is first step of successful procedure. normal settings, GC navigated along with stable support guidewire and inner‐catheter which are sent distally external artery. cases low‐positioned common (CCA) lesions, however, safe without touching lesions often difficult. Herein, we report technique navigation “no‐touching” low‐position CCA plaque using Newton‐shaped stiff inner‐catheter....
