Literature review and DELPHI consensus on follow-up and retreatment of intracranial aneurysms with intrasaccular devices

Background - Intracranial aneurysms are increasingly detected incidentally due to broader use of neuroimaging. Intrasaccular devices are frequently used to prevent rupture, yet standardized follow-up and retreatment strategies remain undefined. We performed a scoping literature review and DELPHI con...

Descripción
Sumario:Background - Intracranial aneurysms are increasingly detected incidentally due to broader use of neuroimaging. Intrasaccular devices are frequently used to prevent rupture, yet standardized follow-up and retreatment strategies remain undefined. We performed a scoping literature review and DELPHI consensus to gauge current practice patterns and expert opinions on managing intracranial aneurysms that were previously treated with intrasaccular devices. - Methods - A DELPHI consensus was conducted during an invite-only meeting of international neurointerventional experts. The process was informed by a scoping literature review and included three iterative rounds of structured questionnaires to establish consensus on follow-up imaging timing, modality, and retreatment decision-making. - Results - Twenty-four experts participated. The literature review identified 16 key studies, which were presented to the panel. For completely occluded aneurysms, MRA at 6 months was preferred by 58% of participants, with annual imaging favored thereafter. For incompletely occluded aneurysms, 6-month DSA followed by annual imaging was recommended. No consensus was reached on the imaging modality for annual follow-up. Retreatment decisions were primarily driven by aneurysm growth (>2 mm). Endovascular retreatment was preferred over open surgery, with risks such as ischemia and rupture identified as key concerns. - Conclusion - This DELPHI consensus highlights current practice trends and open questions in the follow-up and retreatment of aneurysms treated with intrasaccular devices.
