Abstract
Background/aim: The Pipeline Flex Embolization Device (PED Flex) is a new updated version of the PED classic that incorporates anew delivery system to allow facilitation of stent deployment, resheathing, and removal of the capture coil. This study evaluated the PEDFlex in terms of the technical aspects of the procedure and first-year follow-up results.Materials and methods: This retrospective study involved prospectively collected data from May 2015 to August 2017. The primaryendpoint was technical aspects of the procedure, and the secondary endpoint was first-year follow-up results.Results: Forty-nine patients with 59 target intracranial aneurysms were enrolled. Patients’ mean age was 52 years (range 21−71 years),and 31 (63.0%) were female. All aneurysms except for three were unruptured. The mean aneurysm diameter was 8 mm. Forty-sevenpatients with 56 aneurysms were successfully treated. Due to advancement, repositioning, and migration problems, 8 (13.1%) stentswere not deployed and discharged. The total aneurysm occlusion rate was 77.0%. The mortality rate was 4.3%.Conclusion: Our experience shows that the applicability and safety of the renewed delivery system provided by PED Flex for improvingdevice apposition and opening has been proven with one-year angiographic and clinical follow-up results.
