The Prediction of Hemorrhage Transformation by Cerebral Autoregulation in AIS Patient After Endovascular Thrombectomy
China300 participantsStarted 2022-03-01
Plain-language summary
This observational study was designed for observe the cerebral hemodynamics and dynamic cerebral autoregulation (dCA) after endovascular thrombectomy (EVT) in acute ischemic stroke (AIS) patients. And analysis the relationship between the dCA damage degree and hemorrhage transformation (HT) and clinical outcome.
Patients: patients with AIS caused by middle cerebral artery or internal carotid artery occlusion who accepted EVT.
dCA Examination: dCA examinations were performed at 24 hours, 48 hours, 72 hours, and 5 days after EVT.
The objectives of the study were as follows: The changes of cerebral hemodynamics and parameters of dCA in different time periods after EVT were analyzed. So as to determine the correlation between hemodynamics and dCA change and HT and clinical outcome after EVT and to explore the predictors of HT and adverse clinical outcomes.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* (i) age ≥18 years; (ii) complete recanalization of the affected MCA (thrombolysis in cerebral infarction grade 2b or 3); and (iii) sufficient temporal windows to obtain flow signals for the MCA.
Exclusion Criteria:
* (i) inability to perform dCA after EVT due to restlessness; (ii) re-occlusion of the culprit MCA after EVT; and (iii) other conditions such as low cerebral blood flow caused by severe heart disease.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
