We report on a 55-year-old man who developed de novo DAVF in left ACC 5 years after curative transvenous embolization for right ACC. Angiography revealed that the lesion demonstrated more aggressive arteriovenous shunt flow than initial lesion. Successful was performed also second The authors describe possible pathophysiological mechanisms and management strategies this rare occurrence.
Management of pregnant women with brain tumors necessitates difficult decision-making especially for estimating or preventing its intratumoral hemorrhage. A 26-year-old, 19-week woman complaining headache and vomiting was admitted to our hospital. Magnetic resonance imaging (MRI) revealed hydrocephalus a mass lesion without contrast enhancement extending from the left thalamus. To resolve severe symptoms, ventriculoperitoneal shunt inserted, biopsy taken via right ventricle. Pathological...
The brain metastasis of angiosarcoma is very rare, and little known about its clinical features or therapeutic strategy. A 74-year-old male was hospitalized for disturbance consciousness. Radiological examination revealed multiple cerebral hematomas. Gadolinium contrast-enhanced magnetic resonance imaging showed no significant enhancement at any the lesions. To detect a suspected metastatic tumor abscess, full-body scan performed but only poorly enhanced mass in removal cavity caused by...
In a case of 23-year-old female with Rathke's cleft cyst (RCC), unusual changes size and morphology on computed tomography (CT) magnetic resonance images (MRI) were noted in short period 3 weeks after spontaneous rupture.The CT that the intracystic isodensity was changed to hyperdensity.And MRI showed not only decrease lesion but also changing from hypo-and hyperintensity T1-and T2-weighted both images.The intraoperative findings disclosed content milky-like, hemorrhagic.We considered...
症例は46歳の女性である.2013年6月に下顎リンパ節腫脹があり,明るい細胞質を有する中型リンパ球等の増生所見と免疫染色の結果から血管免疫芽球性T細胞リンパ腫(angioimmunoblastic T-cell lymphoma; AITL)と診断,化学療法を行い,同年12月に完全寛解と判断された.翌年5月から同じことを何度も聞くようになり,当科を受診した.記銘力障害,髄液細胞数・蛋白の上昇,MRIでの両側乳頭体や視床周囲の造影効果を伴うFLAIR高信号域を認めた.脳生検にてAITLの再発と診断した.AITLの頭蓋内再発は報告がないが,経過中に中枢神経症状を合併した場合はその可能性を考慮すべきである.
This study evaluated the clinical and angiographic outcome of large aneurysms treated with coil embolization at an acute stage in patients poor-grade subarachnoid hemorrhage (SAH). Between July 1, 2001 June 30, 2004, eight consecutive WFNS grade 5 (15~23 mm) were endovascular within two days followed for least 30 months. There three middle cerebral five internal carotid artery aneurysms. No by craniotomy none survived without treatment. Two died primary brain damage or vasospasm one month....
With the increasing use of carotid artery stenting (CAS), duplex ultrasound (CDU) is important for post-stented patients to check patency CAS. In our institute, stented were treated with dual antiplatelet therapy 3 months after Follow-up on 3-dimensional computed tomography (3D-CT) angiography was performed around 2 years Some also followed up annually CDU. Although major complication CAS reportedly in-stent restenosis (ISR), definitions ISR have not been standardized. From perspective...
Introduction: Proximal stenosis of the subclavian artery (SCA) shows progression to steal syndrome (SSS)/phenomenon (SSP), characterized by retrograde flow in ipsilateral vertebral (VA). Here we describe clinical manifestations and ultrasound findings VA patients with high-grade SCA, role percutaneous transluminal angioplasty (PTA) stenting SCA. Patients: Twelve (male: 10, female: 2; age: 17–86 yr) were selected from among inpatients SCA treated our department between 2009 2015. Results: The...
2015年に発表された5つのランダム化比較試験により, 機械的血栓回収療法の有効性が確立した. 本邦の適正使用指針では発症8時間以内が治療適応となるが, いわゆるwake up strokeやunknown onsetなどでは, その適応に悩む症例がある. われわれは発症から18時間経過した右内頚動脈塞栓症例において, diffusion weighted image (DWI)-fluid attenuated inversion recovery (FLAIR) mismatchの存在から機械的血栓回収療法を施行し神経症状の回復を得た症例を経験した. 本症例では右頚部内頚動脈から中大脳動脈にかけて連続する多量の血栓が存在し, 血栓の飛散が段階的に生じたことでtherapeutic time windowが延長された可能性も示唆された. 発症から時間が経過した症例においても, DWI-FLAIR mismatchが認められる症例では機械的血栓回収療法が有効となる可能性が示唆された.
Although surgery for cerebrovascular disease is an important field neurosurgeons, the number of enforcements may decrease owing to development endovascular intervention.Current neurosurgeons must acquire surgical skills with smaller cases.Here, we present our education method videos and records using information technology facilitate safe reliable neurovascular surgery.The author also disclosed results during their
