Abstract
- Background Unruptured intracranial aneurysms (UIAs) are being detected and treated with endovascular techniques at an increasing rate, with little evidence on the optimal imaging follow-up protocol. We performed a survey of academic neurovascular centers in the United States to assess imaging follow-up strategies and costs after endovascular treatment of UIAs. Methods An online survey on 5-year follow-up strategies of UIAs treated with endovascular techniques was distributed to neurovascular directors of 101 academic neurovascular centers using the American Association of Neurological Surgeons/Congress of Neurological Surgeons Joint Cerebrovascular Section database. An online healthcare marketplace, NewChoiceHealth, was used to calculate costs. Results Of 33 (32.7%) institutions that responded to the survey, 26 (25.7%) provided data suitable for analysis. Nine (34.6%), 10 (38.5%), 4 (15.4%), and 3 (11.5%) centers were located in the northeastern, southern, midwestern, and western regions of the United States. Total costs of 5-year follow-up imaging after primary coil embolization and stent-assisted coiling procedures were $3391–$32,882. Costs for aneurysms treated with flow diversion were $2788–$46,670. Eighteen (69.2%) institutions performed cerebral angiography at 6-month follow-up after coil embolization and stent-assisted coiling, and 19 (73.1%) institutions performed cerebral angiography 6 months after flow diversion. Of institutions, 20% affirmed that they maintained an identical imaging follow-up regimen after treatment of ruptured aneurysms. Conclusions There is significant heterogeneity in imaging follow-up strategies and their associated costs. Stratification of patients by risk of recanalization and corresponding adjustment of follow-up imaging may be 1 strategy to limit unnecessary imaging and control costs. [ABSTRACT FROM AUTHOR]
