Abstract

Background: The Pipeline Embolization Device (PED) has been the only flow-diverting device (FDD) approved by the Food and Drug Administration (FDA) in the U.S. market for nearly a decade, with more FDD choices in the United States following recent FDA approval of the Flow Redirection Endoluminal Device and Surpass. We sought to explore the integration patterns of these devices into practice by U.S. neurointerventionalists. Methods: A 34-question electronic survey was distributed to the U.S. neurointerventional community from different backgrounds (neurosurgery, neurology, radiology) through different organizational links, focusing on technical aspects of device selection and personal preferences/experiences regarding FDD in aneurysms treatment. Results: Responses were collected from 120 neurointerventionalists across the United States; operators from a neurosurgery background constituted the majority of respondents (47.5%; 85% of dual-trained). The largest age block was early-to mid-career operators (70.8% aged 36–50 years). Most participants (78.8%) treated a range of 25–100 aneurysms/year with FDDs, with 49.2% of respondents having all the FDA-approved FDDs available in their centers (80.8% academic practice). Femoral access was used by the 67.7% of respondents, without impact of FDD-device on access-type (89.2%). PED was the most commonly used device (70.9%), with 66.7% of respondents reporting using different FDD based on case specifics. Comparing devices preferences by training backgrounds, more neurosurgical operators endorsed PED as their most commonly used device, whereas more interventional neuroradiologists/neurologists reported Surpass and Flow Redirection Endoluminal Device as their most commonly used devices. Conclusions: The results of this survey identify common themes in FDD choices among neurointerventionalists in the U.S. market, along with their integration patterns of the newly introduced devices into clinical practice.
