Immediate Flow Disruption as a Prognostic Factor After Flow Diverter Treatment: Long-Term Experience with the Pipeline Embolization Device.

摘要: Objective To report long-term results after Pipeline Embolization Device (PED) implantation, characterize complex and standard aneurysms comprehensively, introduce a modified flow disruption scale. Methods We retrospectively reviewed consecutive series of 40 patients harboring 59 treated with 54 PEDs. Aneurysm complexity was assessed using our proposed classification. Immediate angiographic were analyzed previously published grading scales novel Results According to new definition, 46 (78%) classified as complex. Most PED interventions performed in the paraophthalmic cavernous internal carotid artery segments. Excellent neurologic outcome (modified Rankin Scale 0 1) observed 94% patients. Our data showed low permanent procedure-related mortality (0%) morbidity (3%) rates. Long-term follow-up complete occlusion 81% near-total obliteration further 14%. Complete deployment single achieved all 1-year follow-up. scale an independent predictor aneurysm multivariable analysis. All high grade at regardless number or complexity. Conclusions Treatment should be recognized primary management strategy for highly selected cohort predominantly intracranial aneurysms. show that priori assessment postinterventional predict probability may help determine adequate per-aneurysm devices.
