Herrick, MD Neurology & Neurocritical Care ... • However, the Guidelines do not mandate adherence to post-thrombectomy blood pressure goals delineated in the DAWN protocol. Mechanical thrombectomy Endovascular treatment (under fluoroscopic guidance) of removing blood clot from the vessel with thrombectomy device →stent retriever. ... to either IV tPA alone or IV tPA with the addition of mechanical thrombectomy. DIRECT MT is the first RCT clearly demonstrating that mechanical thrombectomy alone using stent retrievers is essentially equivalent to mechanical thrombectomy preceded by iv alteplase in acute ischemic stroke patients with an intracranial large vessel occlusion presenting at a comprehensive stroke center. Patients with basilar thrombosis or tip of the basilar syndrome. Mechanical thrombectomy for acute ischemic stroke: final results of the Multi MERCI trial. In stroke management, latest studies 1) opened the time window for mechanical thrombectomy to 24 hours. The past decade has seen substantial advances in the diagnostic and treatment options available to minimize the impact of acute ischemic stroke. PMID: 29129127; Albers GW et al. Director – Comprehensive Stroke Center . Treatment for patients with acute ischemic stroke is guided by the time from the onset of stroke, the severity of neurologic deficit, and findings on neuroimaging. Thrombectomy within 8 hours after symptom onset in ischemic stroke. Emergency preparedness for Neuroscience teams. Thrombectomy within 8 hours after symptom onset in ischemic stroke. In 2013, optimism related to endovascular treatment of acute stroke was considerably tempered, since the results of three negative clinical studies that compared mechanical thrombectomy with standardised treatment were published in NEJM (“New England Medical Journal”). al. Jovin TG et al. NEJM, 2015 . Smith W, Sung G, Starkman S, et al. Risk of reperfusion in TAPAS trial according to the pre PCI characteristics . Stent retrieval systems are the preferred mechanical thrombectomy devices in the recent times. 2015; 372(1):11-20. Stroke is common; 700,000 ischemic strokes occur in the U.S. each year. Rapid initiation of ivTPA followed by mechanical thrombectomy if there is a large vessel occlusion and tissue that can be saved . In 2015, The New England Journal of Medicine released the results of five separate multicenter, prospective, randomized trials between January and September 2015. indications for mechanical thrombectomy for acute ischemic stroke 2.Learners willdevelopan understanding of the peri procedural care issues for acute ischemic stroke treated with mechanical thrombectomy 3.Learners will be exposed to the different techniques formechanical thrombectomy Several varieties of treatments exist including catheter directed thrombolysis with drugs like t-PA or mechanical thrombectomy. Anesthetic management of thrombectomy during COVID-19 pandemic, Deepak et al., Journal of Neurosurgical Anesthesiology Jovin TG et. NEJM 2018.PMID: 29364767; Powers WJ et al. Any cleared mechanical stent retriever (SR) or aspiration catheter device that is in common use in the operator's region of practice is approved for use. The stroke field particularly the acute treatment has been dramatically changing last few years. 2010. Objective: To evaluate safety of Endovascular Thrombectomy (ET) and predictors of outcome in patients with low Alberta Stroke Program Early CT score (ASPECTS) Background: Recent evidence has established the safety and efficacy of Endovascular Thrombectomy (ET) in patients with acute large vessel occlusion (LVO). Reperfusion therapy Intravenous thrombolysis Endovascular treatment(s) Intra-arterial thrombolytics Mechanical thrombectomy 8. A randomized trial of intraarterial treatment for acute ischemic stroke. Mechanical thrombectomy within 6 hours of stroke onset (with or without intravenous thrombolysis) is effective for treating ischemic stroke caused by large vessel occlusion. Current Best Practice Guidelines: Patient with acute Neurological Deficit related to ischemic stroke Rapid initiation of ivTPA followed by mechanical thrombectomy SVIN Guidance on Mechanical thrombectomy in the era of COVID-19. ... Albers NEJM 2018 Nogueira NEJM 2018 WAKE-UP EXTEND DAWN DEFUSE-3 Last known well “wake up” 4.5-9 hours 6-24 hours 6-16 hours % of patients Endovascular therapy with a stent retriever is recommended for eligible patients. Quite where the manpower will come from is still unclear. Rapid initiation of ivTPA followed by mechanical thrombectomy if there is a large vessel occlusion and tissue that can be saved . The New England Journal of Medicine is a publication of NEJM Group, a division of the Massachusetts Medical Society. Albers, Gregory W., et al. “Thrombectomy 6 to 24 hours after stroke with a mismatch between deficit and infarct.” New England Journal of Medicine 2018. 2015 Apr: 1-11. Mechanical thrombectomy within 6 hours of symptom onset improves functional outcome, and in recent trials has been shown to benefit some patients within 6-24 hours of symptom onset. The main mechanism of clot retrieval by a stent retriever is the initial thrust by the stent on the vessel wall that allows separation of the clot and entrapment of the body of the clot into stent struts.
