Safety and Efficacy of Tiny (≤3 mm) Unruptured Middle Cerebral Artery Aneurysm Treatment: An Analysis of the NeuroVascular Quality Initiative-Quality Outcomes Database Cerebral Aneurysm Registry

Improved imaging modalities have led to an increased detection of intracranial aneurysms, many of which are small. There is uncertainty in the appropriate management of tiny aneurysms. The objective of this study was to use a large, multi-institutional NeuroVascular Quality Initiative-Quality Outcomes Database (NVQI-QOD) to assess the frequency, safety, and efficacy of treatment of tiny, unruptured middle cerebral artery (MCA) aneurysms.
