缺血缺氧是临床常见的一种病理过程,但其机制尚未彻底阐明。一般认为组织缺氧缺血引起的损伤是发生在缺血缺氧的当时,主要是由于组织缺氧,能源产生不足引起。近年有人提出另一种可能性,即组织损伤不但发生在缺氧的当时,更重要的是发生在血管短时阻塞后血液再通时,此时因缺血缺氧引起的综合征称为“再灌流综合征”(Reperfusion Syndrome),又称“无血流恢复现象” Ischemia and hypoxia is a common clinical pathological process, but its mechanism has not been completely elucidated. Hypoxic-ischemic tissue damage is generally believed to occur at the time of ischemia and hypoxia, mainly due to tissue hypoxia, caused by lack of energy. In recent years, it was suggested that another possibility that tissue damage not only occurred in the hypoxia at the time, more importantly, occurs after a short blood vessel occlusion blood recanalization at this time due to ischemia and hypoxia syndrome called “ Reperfusion Syndrome ”(Reperfusion Syndrome), also known as“ no blood flow recovery phenomenon ”
