Gliederung

Text

Objective: Although the formation and rupture risk of an anterior communicating artery (ACoA) aneurysm have been the subject of many studies, no previous study has specifically searched for the relationship of the parent vessels and the impact of their ratio on the development and potential rupture risk of an AcoA aneurysm. The objective of this study is to explore this link and to further analyse the surrounding vasculature of the anterior communicating artery aneurysm.

Methods: We conducted a retrospective analysis of 434 patients: 284 patients with an ACoA aneurysm (121 unruptured and 162 ruptured) and of 150 control patients without an ΑCoA aneurysm. Radiological angiography investigations were used to assess the diameter ratios of the parent vessels in addition to ACoA aneurysm morphology parameters.

Results: When comparing the ruptured to the unruptured cases, no significant difference was observed in the parent vessel diameter ratios. Younger patient age (OR 0.96, P=0.00) and a higher size ratio (OR 1.10, P=0.02) were of prognostic importance after adjusting for other covariables in the multivariable model (Table 4). The A1 diameter ratio and the A2 diameter were not statistically significant (OR 1.00, P=0.99, and OR 3.38, P=0.25 respectively).

Conclusion: In our study we focussed on asymmetry in the parent vessels together with traditional ACoA aneurysm morphological characteristics. We could label younger patient age and a greater size ratio as independent prognostic factors for ACoA aneurysm rupture. We are unable to label parent vessel asymmetry as prognostic factors. To validate our findings, parent vessels asymmetry should be subjected to future prospective studies.
