Abstract:
Objective To investigate the application value of CT perfusion (CTP) imaging for the revascularization treatment in adult patients with Moyamoya disease.Methods Adult patients with Moyamoya disease underwent revascularization in the Department of Neurosurgery,Wuhan No.1 Hospital from July 2009 to December 2016 were analyzed retrospectively.CTP and clinical evaluation were performed before and after 3-6 months of procedure.The modified Rankin Scale (mRS) was used to assess the functional outcomes.Results A total of 20 patients were enrolled in the study,including 9 females and 11 males,aged 29 to 73 years,with an average of 53.5 years.The initial symptom was ischemic stroke in 10 patients,transient isehemic attack in 7 patients,and hemorrhagic stroke in 3 patients.All patients underwent superficial temporal artery-middle cerebral artery bypass grafting plus encephalomyo-synangiosis under general anesthesia.All patients have different degrees of improvement in cerebral blood flow after procedure,and the CTP parameters were significantly improved compared with those before procedure (all P ＜0.05).The clinical symptoms were significantly improved in 3 cases (15％) and recovered in 13 cases (65％) at 6 months after procedure.The proportion of the mRS score 0-2 was significantly higher than that before procedure (90.0％ [18/20] 对 50.0％ [10/20];x2 =7.619,P =0.006).Conclusion CTP can evaluate the cerebral perfusion status in various vascular areas through hemodynamic parameters in early stage,which can effectively guide the operation mode of Moyamoya disease,and evaluate the changes of cerebral perfusion status after procedure as a means of follow-up of the disease.
