Despite the great socioeconomic burden of stroke, there have been few reports stroke statistics in Korea. In this scenario, Epidemiologic Research Council Korean Stroke Society launched "Stroke Statistics Korea" project, aimed at writing a contemporary, comprehensive, and representative report on epidemiology This contains general prevalence behavioral vascular risk factors, characteristics, pre-hospital system care, hospital management, quality outcomes. report, we analyzed most up-to-date...
Importance Optimal blood pressure (BP) control after successful reperfusion with endovascular thrombectomy (EVT) for patients acute ischemic stroke is unclear. Objective To determine whether intensive BP management during the first 24 hours leads to better clinical outcomes than conventional in who underwent EVT. Design, Setting, and Participants Multicenter, randomized, open-label trial a blinded end-point evaluation, conducted across 19 centers South Korea from June 2020 November 2022...
The effects of blood pressure (BP) lowering in patients treated with intravenous tissue plasminogen activator (IV tPA) before endovascular thrombectomy (EVT) are unclear. This study aims to investigate whether intensive and conventional BP management affect outcomes differently, depending on IV tPA administration EVT. In this subgroup analysis the Outcome Patients Treated Intra-Arterial Thrombectomy-Optimal Blood Pressure Control (OPTIMAL-BP; ClinicalTrials.gov Identifier: NCT04205305)...
Importance Nelonemdaz selectively antagonizes the 2B subunit of N -methyl- d -aspartate glutamate receptor and scavenges free radical species. Objective To evaluate whether nelonemdaz enhances clinical outcomes patients with acute ischemic stroke undergoing emergent reperfusion therapy. Design, Setting, Participants This multicenter double-blind placebo-controlled randomized phase 3 trial (December 25, 2021, to June 30, 2023, in South Korea) recruited who met following criteria: National...
BACKGROUND The link between arterial stiffness, measured by estimated pulse wave velocity (ePWV), and outcomes following endovascular thrombectomy (EVT) has not been tested. This study aimed to determine whether ePWV predicts post‐EVT outcome in patients with acute ischemic stroke. METHODS was a secondary analysis of the OPTIMAL‐BP (Outcome Patients Treated With Intraarterial Thrombectomy–Optimal Blood Pressure Control) trial, which enrolled 302 EVT from 19 stroke centers South Korea June...
Purpose We present our experiences of intra-arterial tirofiban injection through a deployed Solitaire stent as rescue therapy after failed mechanical thrombectomy in patients with acute ischemic stroke. Materials and Methods Data on 18 treated adjunctive temporarily were retrospectively reviewed. was used primary device 16 patients. Two received manual aspiration initially. If initial failed, injected intra-arterially the then subsequent performed. Results Fourteen had occlusions middle...
The microcatheter protective technique positions an additional in the parent or side-branching artery to protect it during coil embolization. purpose of this study was describe method and evaluate its efficacy safety as alternative a multiple-microcatheter balloon- stent-assisted for wide-neck aneurysms.A retrospective review 74 patients (43 women; mean age, 59.6 years) with 75 aneurysms treated between January 2003 April 2010 performed. Immediate postembolization angiograms were evaluated...
Importance The associations between blood pressure (BP) decreases induced by medication and functional outcomes in patients with successful endovascular thrombectomy remain uncertain. Objective To evaluate whether BP reductions intravenous medications are associated poor at 3 months. Design, Setting, Participants This cohort study was a post hoc analysis of the Outcome Patients Treated With Intra-Arterial Thrombectomy–Optimal Blood Pressure Control trial, comparison intensive conventional...
Although endovascular technique and related devices continue to improve, recanalization of embolized aneurysm remains a pitfall this approach. The problem how treat the recanalized needs be addressed.To determine outcomes patients undergoing repeat embolization for intracranial aneurysms evaluate impact stent implantation on subsequent recanalization.Between September 2001 2011, we performed retreatment in 162 with total 197 aneurysms. Stent was 68 during retreatment. Clinical morphological...
We aimed to develop and validate machine learning models diagnose patients with ischemic stroke cancer through the analysis of histopathologic images thrombi obtained during endovascular thrombectomy.This was a retrospective study using prospective multicenter registry which enrolled consecutive acute from South Korea who underwent thrombectomy. This included admitted between July 1, 2017 December 31, 2021 6 academic university hospitals. Whole-slide scanning performed for...
BACKGROUND: Protection techniques using stents or microcatheters allow treatment of aneurysms with complex configurations by coil embolization. However, the application these is occasionally limited in wide-neck middle cerebral artery (MCA) acute angularity efferent branch vessel. OBJECTIVE: We describe a looping technique for passage microcatheter and microwire into acutely angled vessel without navigating system through aneurysm lumen. METHODS: To select angulated branch, looped was...
Background Acute ischemic stroke (AIS) more frequently develops in patients with intracranial vertebral artery dissection (VAD) than extracranial VAD, and is associated possible poor clinical outcomes. The aim of this study to compare high-resolution magnetic resonance imaging (HR-MRI) findings features VAD without AIS. Methods Twenty-nine lesions from 27 (15 male 12 female patients; age range = 28-73 years) who underwent diffusion MRI 3T HR-MRI within seven days were included. We classified...
The purpose of this study was to analyze the results an immediate and mid-term angiographic clinical follow-up endovascular treatment for paraclinoid aneurysms.From January 2002 December 2012, a total 113 consecutive patients (mean age: 56.2 years) with 116 saccular aneurysms (ruptured or unruptured) were treated coiling procedures. Clinical outcomes retrospectively evaluated.Ninety-three (82.3%) female. mean size aneurysm 5.5 mm, 101 (87.1%) had wide neck. Immediate catheter angiography...
Unexpected Solitaire stent detachment can occur during mechanical thrombectomy. The purpose of this study was to retrospectively evaluate the influencing factors causing unexpected and clinical outcomes.Between October 2011 December 2013, 232 cases thrombectomy for acute ischemic stroke were performed in 3 centers. During period, we encountered detachments thrombectomies 9 cases.Solitaire stents unexpectedly detached (3.9%) retrieval stents. median patient age 76 years. occlusion sites...
