Clinical Trial of the New Stent Retriever Tron FX for both Proximal and Distal Intracranial Large Vessel Occlusions

BackgroundIn all of randomized controlled trials mechanical thrombectomy, the target vessels were proximal. Herein we report a clinical trial Tron FX stent retriever, including smallest size 2/15 mm for distal intracranial large vessel occlusion (LVO).ObjectiveEligible patients presented within 8 h onset with proximal or LVOs, and 4/20 used as first-line device.MethodsThe primary endpoints rate modified Thrombolysis in Cerebral Infarction (mTICI) grade 2a–3 immediately after using only, mortality 90 d. We compared outcomes between sizes mm.ResultsThe was conducted 50 cases, which 44% LVO 15 cases treated only mm. The overall mTICI 80.0% (75.8% mm, 86.7% mm), 90-day Rankin Scale ≤ 2 improvement National Institute Health Stroke thrombectomy ≥ 10 achieved 66.7% (61.3% mm). 8.0%, symptomatic hemorrhage 24 occurred 2.0% cases.ConclusionIn this FX, included LVO, its efficacy similar safety superior previous studies.
