Abstract:
Objective:To evaluate the hemodynamics of patients with moyamoya disease before and 6 months after cerebral revascularization using phase-contrast magnetic resonance imaging (PC-MRI), and to analyze the risk factors for postoperative cerebral hyperperfusion syndrome (CHS).Methods:Patients with moyamoya disease underwent combined revascularization in Huadong Hospital Affiliated to Fudan University from January 2017 to April 2019 were enrolled retrospectively. PC-MRI was performed before and 6 months after surgery. The blood flow velocity, blood flow and the region of interest (ROI) area of the vascular lumen in internal carotid artery, external carotid artery, superficial temporal artery and vertebral artery were recorded. Multivariate logistic regression analysis was used to determine the independent correlated factors of CHS. Results:A total of 80 patients with moyamoya disease were included, including 35 males (43.75%), aged 42.4±10.1 years (range 19-60 years). The blood flow velocity ( P<0.05), blood flow ( P<0.01) and area of ROI ( P<0.01) of the superficial temporal artery were significantly increased at 6 months after surgery compared with the before surgery, and the blood flow of the vertebral artery was slower compared with the before surgery ( P<0.05). Univariate analysis showed that diabetes, predominant hemispheric operation, preoperative increased superficial temporal artery blood flow rate, reduced internal carotid artery flow, and increased external carotid artery flow were the possible risk factors for occurring CHS in patients with moyamoya disease after surgery. Multivariate logistic regression analysis showed that the predominant hemispheric operation (odds ratio [ OR] 4.627, 95% confidence interval [ CI] 1.019-21.009; P=0.047), preoperative superficial temporal artery blood flow ( OR 1.208, 95% CI 1.053-1.387; P=0.007) and external carotid artery blood flow ( OR 0.139, 95% CI 0.027-0.719; P=0.019) were independently associated with postoperative CHS. Conclusions:PC-MRI can evaluate the hemodynamic parameters of intracranial and extracranial major blood vessels, and it can be used as one of the important basis to evaluate the postoperative risk of moyamoya disease.
