Status: Completed

Conditions: Ischemic Stroke

About

Delipid Extracorporeal Lipoprotein filter from Plasma (DELP) has been found to improve neurological function and life ability of AIS patients and approved for the treatment of AIS by China Food and Drug Administration (CFDA). Our recent study imply that the neuroprotective effect of DELP involved multiple neuroprotective mechanism such as anti-inflammation, free radical scavenging, and decreasing MMP-9. Based on the multiple mechanisms, DELP was used to investigate the effect on acute ischemic stroke receiving endovascular treatment.
