Background/Purpose: Aneurysm size and morphology have been previously correlated with risk of spontaneous rupture. However, there is a lack consensus regarding which morphological parameters are useful for this prediction. The purpose study to assess the ruptured aneurysms in our retrospective cohort compare these findings cited within literature. Materials Methods: Between 2021‐2023, 150 patients subarachnoid hemorrhage secondary were admitted hospital. Two investigators reviewed 3‐dimensional angiograms all evaluate shown correlate rupture previous studies. Results average diameter aneurysm was 6.4 ± 4.4mm. 71% less than 7mm. most common location anterior communicating artery (32.6%) followed by posterior (21.7%). single sac irregular margins (39.1%) multilobulated (39.1%). aspect ratio 1.23 0.47.

Conclusions: may not be good predictor as 7mm commonly better seen cohort. Additionally, such > 2 1.5 predictors compared 1.5.
