摘要

Flow diverters have been in current practice for almost 2 decades, and since then, endovascular treatment of intracranial aneurysms has evolved considerably. Among relatively common complications, stent migration remains an infrequent but clinically significant event. This single patient observational technical note presents a successful endovascular rescue treatment of a proximally migrated flow diverter stent using balloon-assisted remodeling, detected at the eight month follow-up angiography. This strategy allowed the migrated stent to be recatheterized and the treatment to be completed with a second flow diverter stent.
