Feasibility and Safety of Double-Wire Technique for Microcatheter Navigation Beyond Tortuous Internal Carotid Siphon: A Propensity Score-Matched Study.

Background: Severe vessel tortuosity may prevent a microcatheter from reaching a distal vessel. However, the double-wire technique (DWT) may facilitate the procedure. The present study evaluated the feasibility and safety of guiding a 0.

Mechanism and management of acute femoral artery occlusion caused by suture-mediated vascular closure device following neurointervention.

Vascular closure devices (VCDs) show fewer complications related to the puncture site than manual compression but can cause stenosis or occlusion of the common femoral artery (CFA). A patient in her 30s who underwent suture-mediated VCD for haemostasis at the right CFA puncture site after neurointervention showed occlusion of the right CFA on postoperative day 2. Endovascular treatment retrieved the thrombus from the occlusion site, and surgical removal of a suture causing stenosis between the dissected posterior wall intima and anterior wall allowed the resumption of full flow through the right CFA.

Experimental study using phantom models of cerebral aneurysms and 4D-DSA to measure blood flow on 3D-color-coded images.

Background: The current 3D-iFlow application can only measure the arrival time of contrast media through intensity values. If the flow rate could be estimated by 3D-iFlow, patient-specific hemodynamics could be determined within the scope of normal diagnostic management, eliminating the need for additional resources for blood flow rate estimation.

Objective: The aim of this study is to develop and validate a method for measuring the flow rate by data obtained from 3D-iFlow images - a prototype application in Four-dimensional digital subtraction angiography (4D-DSA).

Three-dimensional fusion imaging to assess apposition of low-profile visualized intraluminal support stent for intracranial aneurysm coiling.

Objective: To investigate on three-dimensional (3D) fusion images the apposition of low-profile visualized intraluminal support (LVIS) stents in intracranial aneurysms after treatment and assess inter-rater reliability.

Materials And Methods: Records of all patients with unruptured intracranial aneurysms who were treated with the LVIS stent were retrospectively accessed and included in this study. Two neurosurgeons evaluated the presence of malapposition between the vessel walls and the stent trunk (crescent sign) and the vessel wall and the stent edges (edge malappostion) on 3D fusion images.

Risk, Predictive, and Preventive Factors for Noninfectious Ventriculitis and External Ventricular Drain Infection.

Background: External ventricular drain (EVD) is used for monitoring intracranial pressure or diverting cerebrospinal fluid. However, confirmation of an infection is not immediate and requires obtaining culture results, often leading to the excessive use of antibiotics. This study aimed to compare noninfectious ventriculitis and EVD infection in terms of the risk factors, predictors, prognosis, and effectiveness of care bundle interventions.

Racial and ethnic disparities in self-reported sleep duration: Roles of subjective socioeconomic status and sleep norms.

Objectives: There are racial and ethnic disparities in sleep duration, with members of historically marginalized groups typically reporting shorter sleep than White Americans. This study examines subjective social status (SSS) as a moderator, and variation in ideal sleep norms as a mediator, of differences in sleep duration between racial/ethnic groups.

Methods: Asian, Black, Hispanic, and non-Hispanic White respondents in an online survey reported their typical weeknight and weekend-night sleep duration, along with estimates of ideal sleep duration norms.

A Novel Braided Stent With Customized Simulation Software for Treatment of Intracranial Aneurysms: Multicenter Prospective Trial Before Unrestricted Clinical Application.

Background And Objectives: Planning/guidance software became important tools for physicians' presurgical optimal decision-making. However, there are no intracranial stent products with specifically associated simulation software. We report the "premarket" clinical trial of a new braided stent with a customized simulation software.

Virtual coil images can optimize the visualization of the neckline of intracranial aneurysms during coil embolization: A technical note.

Background: During coil embolization of intracranial aneurysms, the aneurysmal neck needs to be evaluated because coil protrusion into the parent artery may lead to ischemic complications. However, the neck cannot always be clearly visualized due to the limitation of the angiography system and due to the structure of the aneurysm. As a visual aid, we propose a color-coded fusion imaging method that generates "virtual coil" images using preoperative three-dimensional digital subtraction angiography (3D-DSA) images.

Application of Digital Subtraction Angiography in Predicting the Outcomes of Intraoperative Hemorrhage of Juvenile Nasopharyngeal Angiofibroma.

Objective: Juvenile nasopharyngeal angiofibroma (JNA) is a very rare hemorrhagic vascular tumor that predominantly affects adolescent boys. The tumor is relatively large when detected, and the risk of intraoperative bleeding is high. We aimed to examine factors associated with intraoperative blood loss in JNA surgery.

Large-scale network connectivity as a predictor of age: Evidence across the adult lifespan from the Cam-CAN data set.

Changes in brain connectivity patterns as a function of age have been recently proposed to underlie differences in cognitive abilities between young and older adults. These shifts track patterns of increased functional coupling between the executive control network (ECN)-a network of prefrontal and parietal areas that is broadly implicated in externally directed attention and cognitive control-and default mode network (DMN) regions-most commonly associated with internally directed cognitive activity. Although age-related changes in ECN-DMN coupling are well characterized, the contributions of the salience network are less clear.

Comparison of Intra- and postoperative effectiveness of erector spinae plane block and patient controlled analgesia in patients undergoing coronary artery bypass grafting surgery.

The aim of our study was to compare bilateral erector spinae plane block (ESPB) efficacy on pain management with patient controlled analgesia (PCA) during the perioperative period in patients scheduled for coronary artery bypass grafting (CABG). After ethics committee approval (2019-7/31 dated 09.04.

Development of a Virtual Stent Deployment Application to Estimate Patient-Specific Braided Stent Sizes.

A virtual stent deployment application was developed to estimate the appropriate and patient-specific size of a braided stent for patients who undergo endovascular treatment for intracranial aneurysms. Comparing between the simulated deployed and the actual stents, we evaluated the accuracy of the simulation results. Our results indicated that lengths of the virtual and actual stents matched well despite the actual stent being affected by a geometrical change of the parent artery.

False beliefs about sleep and their associations with sleep-related behavior.

Objectives: Understanding the association between sleep-related beliefs and behaviors may be useful in improving sleep health in the general population. This study examines false beliefs about sleep and their associations with self-reported sleep and related behaviors.

Methods: Respondents in an online survey indicated the degree to which they agreed with 20 statements previously identified as sleep myths by experts in the field.

Exploring factors that mitigate the continued influence of misinformation.

Background: The term "continued influence effect" (CIE) refers to the phenomenon that discredited and obsolete information continues to affect behavior and beliefs. The practical relevance of this work is particularly apparent as we confront fake news everyday. Thus, an important question becomes, how can we mitigate the continued influence of misinformation? Decades of research have identified several factors that contribute to the CIE reduction, but few have reported successful elimination.

Clinical outcomes of procedures combining endovascular embolization with a direct surgical approach in a hybrid operating room for the treatment of refractory dural arteriovenous fistulas.

Background: We reviewed the clinical outcomes of a procedure that combines endovascular embolization and a direct surgical approach in a hybrid operating room (OR) for the treatment of refractory dural arteriovenous fistulas (dAVFs).

Methods: All patients with intracranial dAVFs who underwent a procedure combining endovascular embolization and direct surgical approach with biplane angiography or a robotic C-arm system in a hybrid OR between February 2004 and June 2020 were considered. Borden grading, occlusion rate, pre-and post-operative modified Rankin Scale (mRS) scores, and complications were retrospectively investigated.

Four-dimensional digital subtraction angiography for exploration of intraosseous arteriovenous fistula in the sphenoid bone.

Background: Intraosseous arteriovenous fistula (AVF) is a rare clinical entity that typically presents with symptoms from their effect on surrounding structures. Here, we report a case of intraosseous AVF in the sphenoid bone that presented with bilateral abducens palsy.

Case Description: A previously healthy man presented with tinnitus for 1 month, and initial imaging suspected dural AVF of the cavernous sinus.

Visual complications after coil embolization of internal carotid artery aneurysms at the ophthalmic segment.

Background: Coil embolization of aneurysms of the ophthalmic segment of the internal carotid artery (ICA-OphA ANs) has potential risks of visual complications. We analyzed this risk and focused on the relationship of the ophthalmic artery (OphA) origin with the aneurysm neck.

Methods: From January 2003 to April 2018, 179 unruptured ICA-OphA ANs were treated with endovascular surgery in our institution.
