Assessment of intracranial aneurysm rupture based on morphology parameters and anatomical locations.
The aim of the present study was to identify image-based morphological parameters and anatomical locations associated with intracranial aneurysm (IA) rupture. ⋯ Size ratio, height-width ratio, aneurysm inclination angle, aneurysm shape, and aneurysm location might be important for discriminating between ruptured and unruptured aneurysms. Further investigation will determine whether these morphological parameters and anatomical locations will be reliable predictors of aneurysm rupture.

With increasing use of flow-diverting stents for the treatment of intracranial aneurysms, standardized methods and a common language to evaluate angiographic outcomes are needed. Multiple grading scales have been developed for this purpose but none has been widely adopted. ⋯ Existing flow-diverting stent grading scales have low inter-rater reliability for most categories.
