基底动脉尖(TOB)综合征:是指基底动脉顶端血液循环障碍引起的一组临床综合征,由于其发病症状多样,特异性不突出,且临床预后多不良,及早发现及早期干预,对病情估计及提高就治率有积极的临床意义。1局部解剖基底动脉尖(TOB)是基底动脉顶端2cm范围内的五条血管即2条大脑后动脉、两条小脑上动脉以及基底动脉顶端,形成一个“干”字。大脑后动脉是基底动脉的终末支,绕过大脑脚跨过小脑幕切迹,最后达距状裂,供应枕叶内侧面和颞叶的底面,还发出许多小支,供应丘脑的内测部、大脑脚的内侧 Basement apex (TOB) syndrome: refers to the top of the basilar artery blood circulation disorders caused by a group of clinical syndrome, due to its diverse symptoms, specificity is not prominent, and the clinical prognosis is poor, early detection and early intervention, the disease There are positive clinical implications for estimating and improving cure rates. Topographic dissection basilar tip (TOB) is the top of basilar artery 2 vessels within the scope of five vessels that 2 posterior cerebral artery, two superior cerebellar artery and basilar artery top to form a “dry ” word. The posterior cerebral artery is the terminal branch of the basilar artery, bypassing the cerebellar peduncles and traversing the notch of the cerebellum and finally darting, supplying the medial side of the occipital lobe and the underside of the temporal lobe, as well as many small branches that supply the hypothalamus Department, the inside of the brain’s foot
