Abstract Objective To explore the influence of cranioplasty in different periods on hemodynamic changes after decompressive craniectomy due to cerebral trauma.Methods Clinical data from 50 patients underwent cranioplasty after decompressive craniectomy due to cerebral trauma from June 2013 to June 2015 in our hospital were retrospectively analyzed.All patientswere divided into the early-stage group（less than 12 weeks，n=23）and the advanced-stage group （greater than or equal to 12 weeks，n=27）according to repair time.Cranial Doppler ultrasound determined for cerebral blood flow velocity one week before surgery and one week after surgery was provided in all participants.The difference of blood flow velocity of cerebral artery in different periods after cranioplasty was analyzed.Results In the early-stage group，blood flow velocity ofmiddle cerebral artery in the same side before and after surgery was（55.3±8.4）cm/s and （72.6±9.7）cm/s，while the blood flow velocity in the advanced-stage group was（54.7±12.9）cm/s and（63.2±13.4）cm/s respectively，which was not displayed a statistical difference（P＞0.05）.The change amount of MCA blood flow velocity in the same side of the early-stage group was higher than that in the late-stage group，with significant difference（P＜0.05）. There was no significant difference in the defect contralateral MCA blood flow between the early-stage group and the late-stage group（P＞0.05）.Conclusion Cranioplasty in the early stage in decompressive craniectomy patients ismore beneficial to improve cerebral blood supply.

Key words： Cranioplasty Operation opportunity Cerebral blood flow Transcranial Doppler ultrasound
