mechanical thrombectomy centres uk

UHNM has been at the forefront of pioneering the revolutionary Mechanical Thrombectomy stroke treatment since 2009. The University Hospital of North Staffordshire (UHNS) has treated the largest number of cases in the UK. Muir K, Ford G, Messow C et al, on behalf of the PISTE Investigators. The Walton Centre for an urgent procedure called thrombectomy or clot retrieval from a blocked artery in the brain following a stroke. Thrombectomy is a revolutionary treatment that can be used to treat strokes that are caused by a blockage of the largest arteries of the brain by blood clots; this is around 1 in 8 strokes. o Appropriately staffed Recovery facility. After 2 years of planning, the service went live on the on 30 November 2020 and aims to improve access to this life-changing treatment for the local east London community and beyond. Once the procedure is complete, the patient will need to be monitored in the hyperacute stroke unit (HASU) or neurocritical care of the tertiary centre. As one of only two UK sites to have a dedicated 24/7 team, the service has provided specialist care and treatment to more than 500 patients from a potential patient population of three million. 2. Bhatia R, Hill M, Shobha N et al. Our aim is to help you consider how to deliver improvements to healthcare within the available resources. ASPECTS Study Group. To ask the Secretary of State for Health, with reference to the announcement by NHS England of 11 April 2017 on mechanical thrombectomy, when the assessment of the readiness of each of the 24 neuroscience centres to carry out mechanical thrombectomy will be completed; and whether the results of this assessment will be published. Aim: To describe evolving practices in the provision of mechanical thrombectomy (MT) services across the UK during the COVID-19 pandemic, the responses of and impact on MT teams, and the effects on training. Mechanical thrombectomy should allow reperfusion within 6 hours of onset. Stroke remains the second highest cause of death worldwide and a major cause of disability.1 The cost of stroke to the NHS in England is estimated to be around £3 billion per year, within a wider economic cost of about £8 billion.2, About 85% of strokes are ischaemic and most are caused by arterial thrombosis or embolism with resultant loss of neurological function.3 Over one-third of acute ischaemic strokes (AIS) are caused by large artery occlusion (LAO).4 Large artery occlusion refers to occlusion of the terminal part of the internal carotid artery, the proximal middle cerebral artery (MCA), or basilar artery.5 The previous gold-standard treatment, intravenous alteplase, was successful in lysing large clots responsible for LAO in less than 30% of cases and leading to good clinical outcomes in only about 25% of such patients.5,6 In addition, the use of intravenous (IV) thrombolysis was often limited by delayed patient presentation or other contraindications such as wake-up strokes, patient on anticoagulants, recent surgery, or bleeding. INTRODUCTION:The clinical efficacy and cost-effectiveness of mechanical thrombectomy (MT) for the treatment of large vessel occlusion stroke is well established, but uncertainty remains around the true cost of delivering this treatment within the NHS. This document aims to provide an update on indications for mechanical thrombectomy in acute ischemic stroke (AIS) from emergent large vessel occlusion (ELVO) in the anterior circulation. Results of the first 106 endovascular treatments (EVT) are presented here. A clot-retrieval device attached to a guidewire is introduced through the delivery catheter to the site of the occlusion, to remove the clot and re-establish blood flow. 16 Michael Allen, Kerry Pearn, Martin James, Phil White and Ken Stein 4. Lenthall R, McConachie N, White P et al. Unfortunately, not everyone is a candidate for mechanical thrombectomy, because it requires that a patient has a large vessel that’s blocked. Campbell B, Mitchell P, Kleinig T et al, for the EXTEND-IA Investigators. Khoury N, Darsaut T, Ghostine J et al, for the EASI trial collaborators. NHS England will routinely commission MT and issued a document entitled Clinical Commissioning Policy: mechanical thrombectomy for acute ischaemic stroke on 2 March 2018.3 There are approximately 80,000 stroke admissions in England per year.3 Currently, around 12% of all stroke patients receive intravenous thrombolysis and an estimated 8000 patients per year may be eligible for thrombectomy.3 Funding and commissioning of mechanical thrombectomy will be managed through the relevant local NHS England specialised commissioning team.3, Recent evidence suggests that in future, even more patients (including those with unknown time of onset and patients who wake up with strokes) may be eligible for MT. Mechanical thrombectomy (MT) alongside intravenous thrombolysis ... UK centres have adapted local processes at pace to ensure ongoing provision of this vital health service with no significant changes to the reported rate of successful recanalisation. Mechanical thrombectomy can only be carried out in tertiary stroke centres by neurointerventionists, usually interventional neuroradiologists (although other groups also perform this procedure). Mechanical thrombectomy after intravenous alteplase versus alteplase alone after stroke (THRACE): a randomised controlled trial. But just In 2016, St George’s Hospital became the first, and to date only, hospital in the UK to have a fully staffed 24/7 mechanical thrombectomy service for acute stroke. Goyal M, Menon B, van Zwam W et al, for the HERMES collaborators. Mechanical thrombectomy (MT) aims to remove the obstructing blood clot from arteries within the brain directly by introducing a clot retrieval device delivered via an intravascular catheter, thereby restoring blood flow and minimising tissue damage. Berkhemer O, Fransen P, Beumer D et al for the MR CLEAN Investigators. NINDS TPA Stroke Study Group. Health systems need to ensure that MT is delivered to as many patients as quickly as possible. Mechanical thrombectomy (MT) is a very effective, but highly time dependent, reperfusion technique in the management of acute ischaemic stroke caused by large artery occlusion. Imaging for stroke thrombectomy and resource implications 28 Alexander Mortimer 6. In 2016, St George’s Hospital became the first, and to date only, hospital in the UK to have a fully staffed 24/7 mechanical thrombectomy service for acute stroke. CONCLUSION: Mechanical … Twelve cost-effectiveness studies were also identified, including 2 from a UK payer perspective. Summary • Your doctor has found that you / your relative have had a stroke due to a large blood clot causing a blockage to a blood vessel in the brain. Using decision modelling, we aimed to evaluate the cost-effectiveness of secondary transfer by helicopter emergency medical services … Mechanical thrombectomy services: can the UK meet the challenge? The following implementation actions are designed to support STPs and ICSs with the challenges involved with implementing new guidance at a system level. The Atkinson Morley Regional Neurosciences Centre at St George’s University Hospitals NHS Foundation Trust is where the emergency treatment is undertaken with a highly-skilled team with staff from Interventional Neuroradiology, Stroke and Neuroanaesthesia. If reasonable rotas of 1:5 or 1:6 are to be achieved in the majority of Neuroscience centres, there is likely to be a shortfall of 80-90 neurointerventionists _. Norman McConachie Chair UK NeuroInterventional Group The resource impact may be lower if effective treatment results in a reduction in long-term care. thrombectomy in the UK but it is thought that fewer than 10% of those eligible actually receive it. thrombectomy in the UK but it is thought that fewer than 10% of those eligible actually receive it. Generally this means the patient must arrive in the neuroscience centre within 5 hours at the latest. Milne M, Holodinsky J, Hill M et al. Andrew Clifton In this issue, Werring et al1 have set out the evidence, patient selection and tech- nique of one of the most effective new treatments in stroke medicine, with a ‘number needed to treat’ of fewer than three for improved functional outcome. Implementation of mechanical thrombectomy: … The devices in current use are stent retriever devices sometimes with balloon guide catheters for flow occlusion (to reduce forward flow thereby reducing the chance of distal embolisation), direct aspiration catheters, or combined stent retrievers/aspiration catheters.6,7 Acceptable standards are considered to be groin puncture time to start of revascularisation of <45 minutes in at least 65% of patients and end of revascularisation in a time of median ≤60 minutes.4, Figure 1: Patient management algorithm for acute stroke and mechanical thrombectomy, ED=emergency department; IV=intravenous; MT=mechanical thrombectomy; TIA=transient ischaemic attack; CT=computerisedtomography; LAO=large artery occlusion; HASU=hyper-acute stroke unit; ITU=intensive therapy unit, Patient selection is usually made jointly between stroke physicians and neurointerventionists.6 Depending on stroke service configurations in different regions, patients may present directly to a tertiary centre. Implementation of mechanical thrombectomy: … Institute of Translational and Clinical Medicine, Newcastle University, Newcastle upon-Tyne, UK . Bracard S, Ducrocq X, Mas J et al, THRACE Investigators. Feigin V, Forouzanfar M, Krishnamurthi R et al. 1. This has been called the ‘drip and ship’ model.6,8 Communication between centres has to include telephone contact and viewing of images remotely via a picture archiving and communication system (PACS). written by Dr David Jenner, GP, Cullompton, Devon. In 2016, St George’s Hospital became the first, and to date only, hospital in the UK to have a fully staffed 24/7 mechanical thrombectomy service for acute stroke. NHS England has issued commissioning guidance; all thrombectomy centres must be recognised by NHS England as one of their listed centres for this procedure, meet their service specifications, and have regard to the British Association of Stroke Physicians (BASP) Standards for providing safe acute ischaemic stroke thrombectomy services.3,4 The BASP defines a suitable centre as a neuroscience centre incorporating hyperacute stroke units (HASU) embedded within a high quality comprehensive stroke service with access to neurosurgical, neurocritical care and specialist stroke services.4 All centres must enter details about patients admitted with stroke on to the Sentinel Stroke National Audit Programme (SSNAP) database, which is used to audit stroke treatment and outcomes.3, Most patients also have initial treatment with intravenous thrombolysis if they are within the time window and there are no contraindications (see Figure 1).6 NICE interventional procedures guidance (IPG) 548 on Mechanical clot retrieval for treating acute ischaemic stroke7 summarises the procedure; it is usually done under sedation but general anaesthesia is often needed in patients with a reduced level of consciousness or who are uncooperative or agitated.4 Cerebral angiography is done to show the exact location of the arterial occlusion. Introduction The clinical efficacy and cost-effectiveness of mechanical thrombectomy (MT) for the treatment of large vessel occlusion stroke is well established, but uncertainty remains around the true cost of delivering this treatment within the NHS. Barber P, Demchuk A, Zhang J, Buchan A. Validity and reliability of a quantitative computed tomography score in predicting outcome of hyperacute stroke before thrombolytic therapy. The University Hospital of North Staffordshire (UHNS) has treated the largest number of cases in the UK. 10 Peter McMeekin and Martin James 3. Welcome to Guidelines in Practice. Vilela P, Rowley H. Brain ischemia: CT and MRI techniques in acute ischemic stroke. The use of advanced imaging (CT perfusion or MR diffusion and perfusion scans) can demonstrate salvageable brain tissue regardless of the time of onset of the stroke.32 The DAWN trial treated patients who were last known to be well 6 to 24 hours earlier and had a mismatch between the severity of the clinical deficit and the infarct volume (assessed by diffusion-weighted MRI or perfusion CT). Endovascular therapy for ischemic stroke with perfusion-imaging selection. This reflects new evidence building on the Society of NeuroInterventional Surgery (SNIS) recommendations published in 2015.1 Recommendations herein supersede those of previous SNIS guidelines where … van Swieten J, Koudstaal P, Visser M et al. Thrombectomy is more effective than the current standard treatment of thrombolysis (clot-busting drugs) however only a very small minority of patients are currently able to access thrombectomy. The 3-month follow-up data showed 46% of patients were alive and independent (with a mRS of 2 or less) and 58% patients had a … The HERMES collaboration presented patient level data for 1287 patients (634 assigned to endovascular thrombectomy, 653 assigned to usual treatment that included intravenous tPa in 87%).23 Endovascular thrombectomy led to significantly reduced disability at 90 days compared with control (adjusted common odds ratio [cOR] 2.49, 95% confidence interval [CI] 1.76–3.53; p<0.0001).23 The number needed to treat with endovascular thrombectomy to reduce disability by at least one level on mRS for one patient was 2.6.23 The benefits of mechanical thrombectomy over usual care were present in patients aged 80 years or older, those randomised more than 300 min after symptom onset, and those not eligible for intravenous alteplase.23 Mortality at 90 days and risk of symptomatic intracranial haemorrhage did not differ between groups.23 Other meta-analyses have presented very similar conclusions; number needed to treat (NNT) to reduce disability of 2.5, and NNT for an extra patient to achieve independent outcome of 4.25 (3.29–5.99).24,25, The overall complications rate of mechanical thrombectomy is about 4 to 29%, based on recent trial data.6,26 However, many complications are minor and do not affect the eventual outcomes for patients.6 Serious complications include vessel perforation (0.9 to 4.9%), arterial dissection (3%), emboli to new territories (6%), symptomatic intracranial haemorrhage (4.3%), and subarachnoid haemorrhage (2.5%).6,26,27 Vasospasm and vascular access site complications (including dissection, pseudoaneurysm formation, retroperitoneal haematoma, and infection) are other potential complications.6,26. Consultant Stroke Physician, Gloucestershire Royal Hospital. Study Centre: Multicentre UK Trial Duration of Study: 2 years Primary Objective: To determine if endovascular thrombectomy in addition to IV thrombolysis improves the proportion of patients with favourable functional 3 month outcome (defined by modified Rankin 0-2) in patients with acute ischaemic stroke due to occlusion of the middle cerebral or intracranial internal carotid artery. There are a few centres where thrombectomy is available in the UK but there are not enough trained professionals for the services to be rolled out across the country. Currently very few UK centres have the critical mass of specialists and support teams to enable them to provide thrombectomy on a 24/7 basis. Stent-retriever thrombectomy after intravenous t-PA vs. t-PA alone in stroke. Mechanical thrombectomy for acute ischaemic stroke during the COVID-19 pandemic: changes to UK practice and lessons learned D. McConachie, N. McConachie, P. White, R. Crossley, W. Izzath Nottingham University Hospitals NHS Trust Background Mechanical thrombectomy (MT) is a time-sensitive emergency procedure for patients who had ischaemic stroke leading to improved health outcomes. The expected value of perfect information per patient eligible for mechanical thrombectomy in the UK is estimated at £3178. Newcastle upon Tyne Hospitals … Improved reliability of the NIH Stroke Scale using video training. Mechanical thrombectomy services: can the UK meet the challenge? Mechanical Thrombectomy in acute stroke Information for patients, relatives & carers. function googleTranslateElementInit() { Balami J, White P, McMeekin P et al. This is because thrombectomy is a highly-skilled operation. Where ‘drip and ship’ is the only possible model, staff such as radiographers (with the training to perform CT angiograms) in the receiving hospitals may be found to be in short supply and there may be capacity issues within local radiology services. Time to treatment with endovascular thrombectomy and outcomes from ischemic stroke: a meta-analysis. The subsequent management of post-thrombectomy patients is the same as for any other ischaemic stroke. A delivery catheter is inserted, usually through the femoral artery in the groin, and advanced into the occluded artery using X-ray guidance. Regarding thrombectomy centre volumes and maximising access to thrombectomy services for stroke in England: A modelling study and mechanical thrombectomy for acute ischaemic stroke: An implementation guide for the UK PM White1,2, GA Ford3,4, M James5,6 and M Allen5,7 Dear Dr Norrving Re Maximising access to thrombectomy services for stroke in England: a modelling study1 and Mechanical … Endovascular thrombectomy and medical therapy versus medical therapy alone in acute stroke: a randomized care trial. PM White 1 2. Type: Guidance . Evidence base for mechanical thrombectomy in acute ischaemic stroke 5 Phil White 2. Endovascular treatment with stent-retriever devices for acute ischemic stroke: a meta-analysis of randomized controlled trials. In addition, the scans are useful for assessment of the collateral circulation (patients with poor collaterals have poorer outcomes) and early ischaemic changes using the Alberta Stroke Programme Early CT Score (ASPECTS).11 Poorer outcomes are likely if the ASPECTS score indicates extensive early ischaemic changes.6,11 See Table 1 for patient selection criteria based on the National clinical guideline for stroke (5th edition; 2016).12 A patient management algorithm is shown in Figure 1. In the UK only a few stroke centres offer this interventional option. Lyden P, Brott T, Tilley B et al. Organising ambulance services for effective implementation of mechanical thrombectomy 23 Chris Price and John Black 5. Saver J, Goyal M, van der Lugt A et al. Jovin T, Chamorro A, Cobo E et al, for the REVASCAT Trial Investigators. Median stroke onset to IVT start was 120 min. Pract Neurol 2017; 17 (4): 250–251. For instance, 2 specialists referred to the British Society of Neuroradiologists' training guidance for mechanical thrombectomy, which noted that the numbers of fully trained interventional neuroradiologists in the UK would have to double to meet the demands of a 24/7 MT service. This has been called the ‘mothership’ model and is clearly the most efficient pathway in ensuring timely treatment.6,8 However, geographical constraints may make this impossible and patients may present initially to a peripheral centre where they are assessed and transferred to a tertiary centre while receiving IV tissue plasminogen activator (tPa) prior to thrombectomy. PM White . BSNR training guidance for mechanical thrombectomy. o Critical care anaesthetists & nursing staff. 14How many comprehensive and primary stroke centres should the UK have? It has several advantages over IV clot lysis including greater efficacy, a larger treatment window, and it can be performed in patients with some contraindications to IV thrombolysis.3,4.
