Cumulative experience improves the procedures of mechanical thrombectomy

BMC Neurology, 2022
Background Mechanical thrombectomy has been widely performed for large vessel occlusion stroke. The present study aimed to determine whether cumulative experience could improve thrombectomy outcomes.

Mechanical Thrombectomy for Ischemic Stroke

Journal of the American College of Cardiology, 2016
The meta-analysis by Elgendy et al. [(1)][1] on mechanical thrombectomy for acute ischemic stroke pools estimates from 9 randomized trials. According to the study’s selection criteria, only trials that randomized patients within 4.5 h of stroke onset were included.

Predicting Thrombectomy Recanalization from CT Imaging Using Deep Learning Models [PDF]

Medical Imaging with Deep Learning 2022, 2023
For acute ischemic stroke (AIS) patients with large vessel occlusions, clinicians must decide if the benefit of mechanical thrombectomy (MTB) outweighs the risks and potential complications following an invasive procedure. Pre-treatment computed tomography (CT) and angiography (CTA) are widely used to characterize occlusions in the brain vasculature ...

Animal models of ischaemic stroke and characterisation of the ischaemic penumbra [PDF]

, 2018
Over the past forty years, animal models of focal cerebral ischaemia have allowed us to identify the critical cerebral blood flow thresholds responsible for irreversible cell death, electrical failure, inhibition of protein synthesis, energy depletion ...

Mechanical thrombectomy for acute stroke in pregnancy

The Neuroradiology Journal, 2020
Several recent randomised control trials have shown adjunctive endovascular mechanical thrombectomy to be an effective and safe treatment for acute stroke superior to medical therapy alone. Despite this, questions remain over certain groups of patients that have been excluded from these studies, such as pregnant women.

Dual‐Energy CT‐Based Assessment of Thrombotic Heterogeneity for Predicting Stroke Source and Response to Machine Thrombectomy: A Step Toward Visualization Thrombus Treatment

Advanced Science, EarlyView.
The research indicates that dual energy CT scanning can accurately predict the stroke source and clinical outcomes by analyzing thrombus heterogeneity. Based on histopathological analysis of thrombus components, these scans are better able to display thrombus details than standard CT scans, which is helpful for the development of visual navigation ...

Two mechanical thrombectomies in acute ischemic stroke within 48 hours: A case report on a patient with atrial fibrillation

Radiology Case Reports, 2023
Mechanical thrombectomy is the gold standard in treating acute ischemic stroke complicated by large vessel occlusion. However, there are limited studies on repeated mechanical thrombectomy in acute ischemic stroke.

High White Blood Cell Count Is a Risk Factor for Contrast-Induced Nephropathy following Mechanical Thrombectomy for Acute Ischemic Stroke

Cerebrovascular Diseases Extra, 2020
Background: Although mechanical thrombectomy is a standard endovascular therapy for patients with acute ischemic stroke (AIS), the incidence of and risk factors for contrast-induced nephropathy (CIN) following mechanical thrombectomy are infrequently ...

Updates in Mechanical Thrombectomy

, 2016
Strokes are a major source of morbidity and mortality worldwide. The long-standing gold standard in stroke therapy, intravenous administration of tissue plasminogen activator (tPA), is limited by strict timing parameters and modest efficacy in large strokes caused by thrombi in the proximal cerebral vasculature.

Delayed Transplantation of Neural Stem Cells Improves Initial Graft Survival after Stroke

Advanced Science, EarlyView.
Delayed transplantation of human iPSC‐derived neural progenitor cells (NPCs) enhances graft survival, proliferation, and axonal sprouting after stroke. Using bioluminescence imaging and histology in a mouse model of stroke, it is shown that NPC delivery at 7 days post‐stroke is more effective than acute transplantation, highlighting the importance of ...
