Dwell Time of Stentriever Influences Complete Revascularization and First-Pass TICI 3 Revascularization in Acute Large Vessel Occlusive Stroke
In acute ischemic stroke with large vessel occlusion, the interaction between the clot retriever and the stent is critical for achieving successful recanalization. The ideal time of stent deployment (dwell time [DT]) to improve revascularization is currently unknown. We systematically analyzed the effect of different DT on final angiographic and clinical outcomes of patients who underwent mechanical thrombectomy.

Artificial stroke clots: How wide is the gap to the real world?
Especially since the establishment of mechanical thrombectomy as part of the standard stroke therapy, artificial thrombi have become important in the training of interventionalists as well as for the development and testing of devices. So far, these in vitro clots lack direct comparisons with ex vivo thrombi. We therefore compared the histological appearance of dynamically produced clots with that of stroke thrombi acquired during mechanical recanalization.

Validation of Prognostic Models to predict Early Mortality in Spontaneous Intracerebral Hemorrhage: A Cross Sectional Evaluation of a Singapore Stroke Database
Numerous scores have been developed for prognostication of outcomes in intracerebral hemorrhage (ICH). Prediction models must be validated internally and externally before they are considered widely applicable. We aim to independently externally validate and compare three prediction models (ICH score, ICH grading scale (ICH-GS) and simplified ICH (sICH)) in our population, which has not been previously done.

A stent-retrieving into an aspiration catheter with proximal balloon (ASAP) technique: A technique of mechanical thrombectomy
In this study, we evaluated the efficacy of a stent-retrieving into an aspiration catheter with proximal balloon (ASAP) technique that employs a series of thrombus extraction by withdrawing the stent retriever into the aspiration catheter, and continuous aspiration from the aspiration catheter in the first attempt.

Factors Associated with 90-Day Outcomes of Patients with Acute Posterior Circulation Stroke Treated By Mechnical Thrombectomy
Early recanalization of acute posterior circulation stroke due to large intracranial vessel occlusion by mechanical thrombectomy with stent retrievers may improve the outcome of patients. However, evidence of patient selection is still lacking. The study investigated the prognostic factors of acute posterior circulation stroke due to large intracranial arterial occlusion when treated withstent retriever thrombectomy.

Surgical Treatment of Significant Asymptomatic Carotid Stenosis: for the Motion
The quality of intensive medical therapy (IMT) for asymptomatic carotid stenosis (ACS) has improved greatly over the years, and some experts currently consider IMT for ACS as effective as surgical revascularization in reducing the risk of stroke.1,2

Long-term patency of posterior auricular artery –middle cerebral artery bypass for adult-onset moyamoya disease: case report and review of literature
Direct extracranial-intracranial (EC –IC) bypass is one of the fundamental techniques to prevent recurrent stroke in patients with adult-onset ischemic moyamoya disease. When the standard superficial temporal artery (STA) cannot be used for a graft, the posterior auricular artery (PAA) can be a potential surrogate graft.

Results of conservative follow-up or surgical treatment of mayamoya patients who present without hemorrhage, TIA, or stroke
The epidemiology of asymptomatic Moyamoya disease (MMD) is still unclear, and the best management remains controversial. The aim of this study is to evaluate the prognosis of these patients with different management, conservative follow-up or surgical treatment.
