Multicenter Experience with FRED Jr Flow Re-Direction Endoluminal Device for Intracranial Aneurysms in Small Arteries.

摘要: BACKGROUND AND PURPOSE: Flow diverters are emerging as an endovascular treatment alternative for proximally located intracranial aneurysms. However, of aneurysms at and beyond the circle Willis is not well-established. We assessed clinical safety efficacy Re-Direction Endoluminal Device Jr (FRED Jr) dedicated to small-vessel diameters between 2.0 3.0 mm. MATERIALS METHODS: This was a multicenter observational study 42 patients with 47 treated by flow-direction technique FRED Jr. The primary end point absence death, major or minor stroke, TIA. complete near-complete occlusion according O9Kelly-Marotta grading scale follow-up after 1, 6, 12 months. RESULTS: deployment technically successful in all cases. In 39/42 (93%) patients, reached; 3 remaining 1 disabling ischemic stroke recovery discharge, TIA were observed. Two asymptomatic, completely reversible side-branch occlusions occurred. Angiographic (DSA flat panel CT) available month 41/47 (87%), 6 months 27/47 (57%), 11/47 (23%) reached 27/41 (66%), 21/27 (78%), 11/11 (100%) CONCLUSIONS: Deployment safe effective small vessels.
