【摘要】Objective To analyze the changes of CT brain perfusion imaging parameters before and after stent-assisted angioplasty in severe symptomatic intracranial atherosclerotic, and to investigate the pre-operative evaluation value of computed tomography perfusion (CTP) imaging. Methods A total of 58 cases of intracranial stenosis (the degree of stenosis >70% ) were divided into low perfusion group and normal perfusion group through pre-operative CTP imaging. The patients were performed with CTP again to evaluate the cerebral hemodynamic changes 3 months after intracranial stent-assisted angioplasty. The relative perfusion parameters including regional cerebral blood flow (rCBF).regional cerebral blood volume (rCBV), regional mean transit time (rMTT), and regional time to peak (rTTP) in both groups were compared. The curative effects of both groups were compared. Results rCBF, rMTT, and rTTP were improved significantly (P < 0.05) in the low perfusion group after treatment. The post-treatment follow-up indicated that the incidence of ischemic events in the low perfusion group were significantly lower than the normal perfusion group (P < 0. 05). The number of patients with mRS ≤ 2 was increased
