摘要
颈内动脉狭窄或闭塞的临床表现与脑血流代偿密切相关。目前认为，脑血流代偿主要通过以下3种方式实现：侧支循环建立，新血管形成，脑血管自动调节。其中，侧支循环在代偿中起着重要作用，主要包括前交通动脉、后交通动脉、眼动脉和其他侧支循环。脑微血管重建是颈内动脉重度狭窄或闭塞时的代偿反应，可能会增高缺血性卒中患者的存活率。
The clinical manifestation of internal carotid artery stenosis or occlusion is closely associated with the compensation of cerebral blood flow. At present, it is regarded that the compensation of cerebral blood flow is mainly via the following 3 modes： establishment of collateral circulation, neovascularization, and cerebrovascular autoregulation. Among them, collateral circulation plays an important role in the compensation, mainly including anterior communicating artery, posterior communicating artery, ophthalmic artery, and other collateral circulation. Microvascular reconstruction is a compensatory reaction during internal carotid artery severe stenosis or occlusion, and it may increase the survival rate in patients with ischemic stroke.
