Advances in mechanical thrombectomy for acute ischemic stroke due to large vessel occlusion

Acute ischemic stroke (AIS) is a significant cause of global morbidity and mortality, with functional implications for quality of life and long-term disability. The limitations of intravenous thrombolytic therapy for the treatment of AIS, especially for emergent large vessel occlusion (ELVO), have paved the way for alternative therapies and the rapidly evolving landscape of endovascular therapy (EVT). Here, we summarize the major landmark trials that have advanced the field largely due to ongoing biomedical engineering device development that have translated into significantly improved clinical outcomes. Our review describes the clinical success of EVT, and current and future trends.
