Intracranial aneurysms with perianeurysmal edema: Long-term outcomes post-endovascular treatment

摘要

Background and purpose: Perianeurysmal edema is rare and is associated with expansion of intracranial aneurysms despite adequate endovascular treatment. The natural history of this condition is poorly understood. We present a case series of perianeurysmal edema to investigate the incidence, natural history and management of these aneurysms.
