Progressive ischemic stroke is one of the major diseases damaging the health of Chinese people. Its pathogenesis is complex and there are many influencing factors, but the treatment methods are limited. In recent years, the rapid development of neuroimaging and the results of various clinical trials have been reported in succession, which have made new progress in the clinical diagnosis and treatment of progressive ischemic stroke. This paper summarizes the progress of progressive ischemic stroke, introduces its pathogenesis (including increased intracranial pressure and reduced perfusion pressure, thrombosis progression, hemorrhagic transformation, cerebral edema, and inflammatory response), influencing factors, predictive indicators (including image indicators, biochemical indicators, and molecular biology indicators) and treatment (including admission to “stroke unit”, intravascular treatment, platelet aggregation inhibition treatment, anticoagulation treatment, and general treatment), to provide references for preventing the occurrence and development of progressive ischemic stroke, assessing the condition, guiding treatment and improving the prognosis.
