On the basis of current evidence, complications of stent-assisted coiling for ruptured intracranial aneurysm may be affected by the method of antiplatelet administration.

The objective of this study was to evaluate susceptibility changes caused by iron accumulation in cognitive normal (CN) elderly, those with amnestic mild cognitive impairment (aMCI), and those with early state AD, and to compare the findings with gray matter volume (GMV) changes caused by neuronal loss. The participants included 19 elderly CN, 19 aMCI, and 19 AD subjects. The voxel-based quantitative susceptibility map (QSM) and GMV in the brain were calculated and the differences of those insid

Contrast leakage or a pseudoaneurysm or both seen on angiography are active bleeding foci and targets for therapy in patients with acute bleeding in the head and neck area. Despite different bleeding-control strategies according to vessel involvement, endovascular treatment is safe and effective for controlling hemorrhage.

Our study demonstrates that DES shows long-term stability and safety, and results in good clinical outcomes with a low rate of restenosis.

The Solitaire system has recently been increasingly used for acute stroke treatment in which the endothelial safety immediately after its use has not been evaluated. This study was performed to evaluate the endothelial status when using a Solitaire system in a canine arterial occlusion model. Thromboembolic occlusion of both internal maxillary arteries was achieved in five mongrel dogs. In each animal, the Solitaire system (ev3, Irvine, CA, USA) was used for primary thrombectomy on the right sid

Intracranial atherosclerosis against optimal medical treatment requires reperfusion therapy to improve the clinical outcome. We compared outcomes between self-expandable stent (SES) and/or balloon-expandable stent (BES) and present the potential advantages of using each stent. During the same time frame before and after Wingspan introduction to our institute, 115 consecutive patients underwent intracranial stenting for symptomatic severe intracranial stenosis against optimal medical treatment us

Our real world experience indicated a slightly lower overall prevalence of incidental intracranial saccular aneurysms than previously reported. The prevalence increased with age in women but not in men.

Background The previous studies reported increased concentrations of metallic ions, imbalanced Na+ and K+ ions, and the increased mobility of protons by microstructural disruptions in Alzheimer's disease (AD). Purpose (1) to apply a high-frequency conductivity (HFC) mapping technique using a clinical 3T MRI system, (2) compare HFC values in the brains of participants with AD, amnestic mild cognitive impairment (MCI), and cognitively normal (CN) elderly people, (3) evaluate the relationship betwe

'Carotid S occlusion' usually presented with border-zone infarction and endovascular management of the lesions was feasible. A relatively successful clinical outcome could be achieved after successful revascularization.

Our study revealed that FSI simulation before and after intracranial stenting was feasible despite of limited vessel wall dimension and could reveal change of WSS as well as flow velocity and wall pressure.

BACKGROUND: Simultaneous use of balloon catheters with embolic materials can cause unwanted rupture of the balloon occlusion catheters, which might cause a serious problem. Therefore, knowledge of the compatibility of occlusion balloon catheters with liquid embolic materials is important in various interventional procedures. OBJECTIVE: To determine the compatibility of occlusion balloon catheters with commonly used embolic materials in vitro. METHODS: We used three types of occlusion balloon cat

We report the case of a 55-year-old woman who presented with a severe pain and a mass in the proximal portion of the medial calf. On sonography, the lesion appeared as a poorly defined hypoechoic lesion with interspersed muscle bundles. A total excision of the lesion was performed. On microscopic examination, the specimen demonstrated cystic lesions surrounded by fibrous walls within the muscle bundles. A ruptured intramuscular ganglion cyst diagnosis was made based on the histopathologic findin

If a guidewire is not passed through using a trans-femoral approach while performing the landmark technique, changing the stenting route from brachial to the femoral artery can be useful after securing the lumen in the occluded subclavian artery after angioplasty via the brachial artery.
