脑缺血后血管发生：调控机制和影像学评价

Angiogenesis after cerebral ischemia： regulatory mechanisms and imaging evaluation

血管发生是脑缺血后机体作出应答的重要病理生理学过程。血管发生在脑缺血后数小时即被启动，能促进神经元重塑和神经功能恢复。研究表明，脑缺血后的微血管密度与卒中患者的远期存活率呈正相关。文章就脑缺血后血管发生的调控机制和影像学评价进行了综述。

Angiogenesis is an important pathophysiological process of body response after cerebral ischemia. Angiogenesis is activated in a few hours after cerebral ischemia. It can promote neuronal remodeling and neurological function recovery. Studies have shown that the microvessel density is positively correlated with the long-term survival rate in patients with stroke after cerebral ischemia. This article reviews the regulatory mechanisms and imaein~ evaluation of angiogenesis after cerebral ischemia.
