Lattice Flow Diverter Is Novel Flow Diversion Device

Background: Intracranial aneurysms (IAs) affect approximately 3% to 5% of the population and are the primary cause of nontraumatic subarachnoid hemorrhage. A lattice flow diverter (LFD) is a novel FD using the MIROR (metal interface reassembly for optimizing restenosis) surface technology with innovative delivery system equipped with self-expanding medical balloon. The MIROR technology reduces the formation of oxide rust layers and platelet aggregation, thus lowering the risk of thrombogenicity. Although premarket clinical trial reported an occlusion rate of 85.9% and in-stent stenosis (ISS) of 0.78% of IAs treated with LFD at a 12-month follow-up, there is no study to compare the efficacy and safety of LFD versus well-established Pipeline Embolization Device Flex (PED Flex). Objective: To compare outcomes of LFD and the PED Flex for unruptured IAs (UIAs) using propensity score matching. Design: Single-center retrospective analysis. Methods: The authors analyzed UIAs in consecutive p more...
