説明

<jats:p>Acute ischemic stroke (AIS) afflicts millions of individuals worldwide. Despite the advancements in thrombolysis and thrombectomy facilitating proximal large artery recanalization, the resultant distal hypoperfusion, referred to “no-reflow” phenomenon, often impedes the neurological function restoration in patients. Over half a century of scientific inquiry has validated the existence of cerebral “no-reflow” in both animal models and human subjects. Furthermore, the correlation between “no-reflow” and adverse clinical outcomes underscores the necessity to address this phenomenon as a pivotal strategy for enhancing AIS prognoses. The underlying mechanisms of “no-reflow” are multifaceted, encompassing the formation of microemboli, microvascular compression and contraction. Moreover, a myriad of complex mechanisms warrant further investigation. Insights gleaned from mechanistic exploration have prompted advancements in “no-reflow” treatment, including microthrombosis therapy, which has demonstrated clinical efficacy in improving patient prognoses. The stagnation in current “no-reflow” diagnostic methods imposes limitations on the timely application of combined therapy on “no-reflow” post-recanalization. This narrative review will traverse the historical journey of the “no-reflow” phenomenon, delve into its underpinnings in AIS, and elucidate potential therapeutic and diagnostic strategies. Our aim is to equip readers with a swift comprehension of the “no-reflow” phenomenon and highlight critical points for future research endeavors.</jats:p>
