A life-saving clot retrieval procedure can save lives and prevent disability of patients with ischaemic stroke who get to hospital in time. In New Zealand, 90% of clot retrieval procedures are performed under general anaesthesia. Many anaesthetic drugs can affect blood pressure (BP) and blood flow within the brain. Increasing BP during the procedure could provide additional benefits in this devastating disease. A large trial is needed to investigate BP management during clot retrieval.', 'detailedDescription': 'Internationally stroke ranks second among all causes of disability and is adding to considerable worldwide healthcare burden. Over the last 5 years a new procedure to remove clots (Endovascular Thrombectomy - EVT) has been effective for the treatment of acute large strokes, with significant reductions in long term patient disability compared to standard treatment. However, there minimal guidance on blood pressure management during the procedure. The brain is especially vulnerable to low blood pressure during the acute stroke period due to low blood supply, impairment of how the brain regulates blood flow and further falls in blood flow to the brain. High blood pressure may be beneficial due to increased blood flow in areas at risk during this time. It could be harmful due to brain injury process, swelling, and bleeding into the brain. Conversely, relatively low blood pressure could be harmful. Current evidence is limited to large observational studies. This randomised controlled study will examine the safety and efficacy of two systolic blood pressures (SBP) management arms during general anaesthesia for EVT on outcomes in patients with acute ischaemic stroke.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients diagnosed with anterior circulation stroke (ICA or proximal M1 or M2 segment of MCA) treated with ECR within 6 hrs of stroke onset and ECR patients presenting within 6-24 hours and favourable penumbra on perfusion scanning (see criteria 1-3).\n\nAdditional criteria in the 6 to 24-hour window.\n\n1. \'wake up\' stroke;
