Thrombectomy Versus Best Medical Management in Large Vessel Occlusion Stroke Patients Presenting Beyond 24 Hours and With Presence of Collateral Flow on CT Angiography

The goal of this clinical trial is to investigate if endovascular treatment (EVT) can effectively treat patients with large vessel occlusion (LVO) who present beyond the typical 24-hour window after symptom onset. The main questions it aims to answer are: * Can EVT improve functional independence at 90 days for patients treated after 24 hours? * What is the safety profile of EVT in this delayed treatment group compared to best medical management (BMM)? Researchers will compare EVT outcomes in patients presenting after 24 hours to those receiving BMM to see if EVT offers significant benefits. Participants will: * Receive either EVT or BMM based on their eligibility. * Undergo CT angiography to assess collateral circulation and to confirm the presence of LVO. * Be followed for 90 days to evaluate functional outcomes and safety measures.
