The Prediction of Hemorrhage Transformation by Cerebral Autoregulation in AIS Patient After Endovascular Thrombectomy
Sponsor: Xuanwu Hospital, Beijing
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.
Official title: Research of the Prediction of Hemorrhage Transformation and Clinical Outcome by Cerebral Autoregulation After Endovascular Thrombectomy in Acute Ischemic Stroke Patients Caused by Middle Cerebral Artery or Internal Carotid Artery Occlusion.

Interventions
endovascular thrombectomy
All individuals were anesthetized, with local or general anesthesia dependent on the cooperation level of the patient. During the procedure, it was mandatory to administer intravenous heparin to maintain the activated clotting time between 250 and 300 s, except for subjects who received intravenous alteplase. The procedures were performed through the femoral artery. The selection of stent retriever type and size, along with any required devices, such as guide wires and catheters, as well as the intervention strategy, was at the interventionists' discretion.
