BACKGROUND Cerebral angiography, although invasive, remains the most accurate diagnostic tool for neurovascular diseases. While transfemoral cerebral angiography (TFCA) is conventional approach, transradial (TRCA) has gained interest due to potential benefits, such as reduced hematoma risk and shorter recovery times. However, procedure times influencing factors remain debated. This retrospective study from a single center aimed compare time in 100 patients undergoing TFCA 93 TRCA. MATERIAL...
The safety of the stent-assisted coil embolization (SAC) technique for acutely ruptured aneurysms has not been established yet. SAC is believed to be associated with a high risk thromboembolic and hemorrhagic complications in acute subarachnoid hemorrhage (SAH). aim this study was evaluate efficacy setting aneurysm.
Extra-domain B of fibronectin (EDB-FN) is an alternatively spliced form with high expression in the extracellular matrix neovascularized tissues and malignant cancer cells.In this study, we evaluated practicality using EDB-FN as a biomarker therapeutic target for gliomas (MGs), representative intractable diseases involving brain tumors.Methods: The microarray-and sequence-based patient transcriptomic database 'Oncopression' tissue microarray MG samples were analyzed.EDB-FN data extracted...
The leptin receptor-deficient db/db mouse is a rodent model of type 2 diabetes and obesity. Diabetes in mice shows an age-dependent progression, with early insulin resistance followed by secretory defect resulting profound hyperglycemia. However, there insufficient data on agedependent changes energy metabolism mice. We demonstrated decrease the respiratory exchange ratio (RER), calculated VO2/VCO2, RER determined indirect calorimetry, was 1.03 under 6 weeks age, which were similar to those...
The purpose of this study was to evaluate the effectiveness middle meningeal artery embolization (MMAE) in elderly high-risk patients with symptomatic chronic subdural hematoma (CSDH) terms reduction volume and recurrence rate.We retrospectively reviewed data prospectively collected from nine who underwent 13 MMAE for CSDH between June 2017 May 2022. measured using a computer-aided volumetric analysis program. Hematoma changes during follow-up period were analyzed clinical outcomes...
Abstract BACKGROUND Thin-walled regions (TWRs) of aneurysm surfaces observed in microscopic surgery are thought to be vulnerable areas for growth and rupture unruptured intracranial aneurysms (UIAs). OBJECTIVE To identify hemodynamic features TWRs by using computational fluid dynamics (CFD) analyses middle cerebral artery bifurcation (MCAB) aneurysms. METHODS Nine patients with 11 MCAB were enrolled, their identified. CFD analysis was performed 3 parameters: pressure, wall shear stress...
The authors report on a case of intravascular ultrasonography (IVUS)-guided stent angioplasty for iatrogenic extracranial vertebral artery (VA) dissection in 49-year-old man after coil embolization an unruptured aneurysm the right posterior inferior cerebellar artery. Insignificant dissections occurred during procedure. Postoperatively, patient experienced gradually worsening neck pain and headache, follow-up angiography 8 months revealed expansion dissection. underwent with IVUS guidance...
Background Subdural hygromas are often found bilaterally in spontaneous intracranial hypotension (SIH). They frequently progress to chronic subdural hematomas (CSDHs), and if the formed, it is difficult consider SIH as an underlying cause. Whether or not among patients presenting bilateral fluid collections (hygromas CSDHs) clinically important because treatment strategy should be different between them. Objectives We designed a retrospective case‐control study figure out differential...
<b><i>Background:</i></b> Clinical outcome in patients with acute ischemic stroke (AIS) caused by large vessel occlusion (LVO) is not satisfactory if reperfusion treatment fails or tried. <b><i>Aims:</i></b> We aimed to assess the efficacy and safety of urgent superficial temporal-to-middle cerebral artery (STA-MCA) bypass surgery selected patients. <b><i>Methods:</i></b> Patients who were diagnosed LVO-induced AIS...
Objective The feasibility and usefulness of transradial catheterization for coronary neuro-intervention are well known. However, the anatomical change in catheterized radial artery (RA) is not understood. Herein, we present results ultrasonographic observation RA after routine cerebral angiography (TRCA). Methods Patients who underwent TRCA with pre- post-procedure Doppler ultrasonography (DUS) were enrolled. We then recorded retrospectively reviewed diameter any complicated features...
Objective Stent-assisted coil embolization of intracranial wide-necked aneurysm requires long-term postoperative antiplatelet therapy to prevent in-stent thrombosis. This study aimed demonstrate results temporary stent placement for coiling wide necked small aneurysms, which eliminated need agents, and discuss its feasibility safety. Methods Data 156 patients who underwent stent-assisted between 2011 2014 were retrospectively analyzed. Thirteen cases included, their clinical radiological...
Abstract BACKGROUND Many physicians consider aneurysmal wall enhancement (AWE) on high resolution-vessel imaging (HR-VWI) as an biomarker of unstable unruptured intracranial aneurysms (UIAs). OBJECTIVE To evaluate the clinical value different AWE signal intensities (SIs) by assessing correlation between SIs and surgical findings rupture risk assessment tools. METHODS Twenty-six patients with 34 who underwent clipping were included. The corrected SI was calculated comparing T1-weighted images...
Large to giant middle cerebral artery aneurysm is a challenging disease, especially when incorporating important perforating arteries. Surgical risk increases by perforator infarction and anatomical complexity. In this clinical setting, extensive consideration of surgical options needed. The two cases described here were unruptured had rather stable wall. Because their large size, hardness incorporated arteries, it was not affordable isolate them means clipping or trapping. procedure as the...
ABSTRACT This study was designed to investigate (i) extracellular matrix specify adhesive substrates human dura mater cell (hDMC); (ii) the alteration on adhesion‐related molecules in hDMC; and (iii) secreted metalloproteinases (MMPs) linked with remodeling after exposure inflammation. The hDMC cultured from tissue, studies were performed co‐culturing macrophage like THP‐1 cells (Mϕ). adhesion of co‐cultured through collagen I increased 6.4‐fold IV 5.0‐fold compared naïve ( p < 0.001)....
