Abstract Objective Lately, morphological parameters of the surrounding vasculature aside from aneurysm size, specific for location, e.g., posterior cerebral artery angle basilar tip aneurysms, could be identified to correlate with risk rupture. We examined further image-based that growth or rupture aneurysms. Methods Data 83 patients aneurysms (27 not ruptured; 56 ruptured) and 100 control were assessed (50 without 50 anterior circle Willis). Anatomical analyzed, as well vasculature, namely asymmetry P1 vertebral arteries. Results Patients showed no significant increase in compared circulation, neither was there a difference between cases ruptured unruptured Furthermore, we observed correlations size number lobuli Conclusion rupture, lobulation associated (surrounding vasculature) asymmetry. Therefore, vessels does seem promising parameter evaluation probability future studies.
