Objective The purpose of this study was to observe the changes of superficial temporal artery in adult patients with moyamoya angiopathy before and after combined revascularization and explore better follow-up strategies and monitoring indicators. Methods The diameter and hemodynamic parameters (peak systolic velocity, end diastolic velocityand resistance index) of bilateral superficial temporal artery were examined by color Doppler ultrasound before and 10 days, 30 days, 6 months and 1 year after combined revascularization. Results Color Doppler ultrasound could directly show the stenosis and occlusion of superficial temporal artery. There was statistical difference in the resistance index at each time point after operation between bilateral superficial temporal artery (P＜0.05), and there was statistical difference in the resistance index of each time point after operation compared with that before operation (P＜0.05). There were two peaks in the postoperative parameters, at 10 days and 1 year, and there was a low period from 30 days to half a year after operation.Conclusion Color Doppler ultrasound can provide abundant information of the superficial temporal artery, and the resistance index may be the most valuable evaluation index. The follow-up between 30 days to half a year and one year after operation should be strengthened.
