Importance Prior trials of extracranial-intracranial (EC-IC) bypass surgery showed no benefit for stroke prevention in patients with atherosclerotic occlusion the internal carotid artery (ICA) or middle cerebral (MCA), but there have been subsequent improvements surgical techniques and patient selection. Objective To evaluate EC-IC symptomatic ICA MCA, using refined operator Design, Setting, Participants This was a randomized, open-label, outcome assessor–blinded trial conducted at 13...

Background: Hemodynamic evaluation is crucial in assessing stroke risk patients with symptomatic intracranial atherosclerotic stenosis (sICAS). A new CFD model based on high-resolution MRI and phase-contrast MR angiography was developed to calculate translesional pressure ratio, called MRI-derived ratio (MPR). Purpose: We plan conduct two studies assess the diagnostic accuracy of MPR detecting insufficient brain perfusion its predictive value for clinical outcomes sICAS patients. Methods: In...

Background Data concerning restenosis following successful recanalization of non-acute internal carotid artery occlusion (ICAO) are scarce. This study was conducted to identify the incidence and predictors ICAO. Methods We reviewed (defined as >70% or reocclusion) among 252 consecutive patients with Baseline, imaging, surgery-related characteristics were analyzed assess their association restenosis. A scoring system developed high-risk for Results During a median follow-up 12.6 months,...

Patients with symptomatic internal carotid artery (ICA) or middle cerebral (MCA) occlusion haemodynamic insufficiency are at high risk for recurrent stroke when treated medically. The Carotid Middle Occlusion Surgery Study (CMOSS) trial is an ongoing, government-funded, prospective, multicentre, randomised controlled trial. CMOSS will recruit 330 patients ICA MCA (parallel design, 1:1 allocation ratio) and insufficiency. Participants be allocated to best medical treatment alone medicine plus...

Knowledge regarding the influence of arterial remodeling patterns on plaque characteristics and postoperative outcomes in patients with severe basilar artery (BA) stenosis after endovascular treatment is lacking. The purpose this study was to investigate characteristics, patterns, perioperative BA stenosis.A prospective cohort conducted symptomatic who underwent high-resolution MRI before treatment. index, burden, area were evaluated for each plaque. Based index calculated by MRI, classified...

Carotid artery stenting (CAS) has become an alternative strategy to carotid endarterectomy for stenosis. Residual stenosis was independent risk factor restenosis, with the latter affecting long-term outcomes of CAS. This multicenter study aimed evaluate echogenicity plaques and hemodynamic alteration by color duplex ultrasound (CDU) examination investigate their effects on residual after CAS.From June 2018 2020, 454 patients (386 males 68 females) a mean age 67.2 ± 7.9 years, who underwent...

To examined the curative effect of vitreous injection with ranibizumab,laser coagulation and cryotherapy in treating stage 3 Coats' disease exudative retinal detachment.Seventeen patients were enrolled study. All eyes treated ranibizumab as initial treatment, subsequent treatment depended on absorption subretinal fluid, Including laser photocoagulation. Repeat for two intervals occurred ≥1 month. The mean follow-up time was 24.12 ± 5.99 months. main data evaluation outcome measurements...

While drug-eluting stents (DES) have been widely applicated in coronary stenosis, uncertainty persists concerning the relative performance and clinical benefit patients undergoing vertebral artery stenting when compared with a bare metal stent (BMS). We sought to compare in-stent restenosis (ISR) rates of DES BMS treatment ostium (VAO) stenosis.This study analyzed single-center prospective cohort. Over 1.5-year period (January 2014-June 2015), 137 consecutive underwent VAO involving...

Abstract Purpose Cerebral blood flow (CBF) and glucose metabolism are important significant factors in ischaemic cerebrovascular disease. The objective of this study was to use quantitative hybrid PET/MR evaluate the effects surgery treatment on symptomatic unilateral internal carotid artery/middle cerebral artery steno-occlusive Methods Fifteen patients diagnosed with disease were evaluated using a TOF system (Signa, GE Healthcare). CBF value measured by arterial spin labelling (ASL)...
