The Pipeline Flex Embolization Device with Shield Technology (PED Shield) and the Lattice Flow Diverter (LFD) are two surface-modified FDs that have shown promising efficacy for mitigating procedure-related ischemic events in prior single-arm or retrospective series. Nevertheless, head-to-head comparative data between these two surface-modified flow diverters remain scarce, and prospective randomized clinical trials are warranted to corroborate their differential performance in lowering ischemic complication risks.This prospective, multicenter randomized controlled trial (RCT) was designed to compare the efficacy of PED Shield versus LFD in reducing ischemic complications after endovascular treatment of UIAs. A total of 196 eligible participants who meet the predefined inclusion and exclusion criteria will be enrolled in the trial. The primary outcome measure is the incidence of new diffusion-weighted imaging (DWI)-positive lesions on brain magnetic resonance imaging (MRI) within 48 hours after the procedure. The secondary outcome measures consist of perioperative symptomatic ischemic events, all-cause mortality and disability rate during the follow-up period, delayed aneurysm rupture at the 6-month follow-up, complete aneurysm occlusion rate, incidence of major in-stent stenosis (stenosis degree \\>50%) at the 6-month follow-up, and the number of new DWI-positive lesions within 48 hours post-procedure.",[94,95],"Intracranial Aneurysms","Flow Diverter",[97,98,99],"intracranial aneurysms","flow dierters","surface-modified","2026-06-29",{"date":102,"type":103},"2026-07-01","ACTUAL",{"date":105,"type":103},"2026-05-21",{"date":107,"type":88},"2027-09-30",{"name":5,"class":6},1]
