脑侧支循环与缺血性卒中

Cerebral collateral circulation and ischerrdc stroke

脑侧支循环的建立是脑缺血后的一种继发性代偿机制。脑缺血后，内源性促血管生长因子表达上调，启动血管发生和动脉生成，加速缺血区侧支循环的建立。部分药物可促进缺血性卒中后的侧支循环建立，有可能改善患者预后。

The establishment of cerebral collateral circulation is a secondary compensatory mechanism after cerebral ischemia. The expression of endogenous angiogenic growth factors is upregulated, angiogenesis and arteriogenesis are initiated, and the establishment of collateral circulation is accelerated after cerebral ischemia. Some drugs may promote the establishment of collateral circulation after ischemic stroke and improve the prognosis of patients.
