Observed rupture of unruptured intracranial aneurysms

Abstract

Aim: To study the aneurysms where pre and post-rupture imaging was available to determine the impact of rupture on morphology and size of the aneurysm.

Methods: A retrospective case series where all cases of ruptured aneurysms over a 5-year period were evaluated and cases identified where pre and post rupture imaging was available. These were then studied in detail.

Results: The actual change in the volume of the aneurysm pre and post rupture was quite small and the underlying shape/morphology did not change at all.

Conclusion: Post-rupture morphology of aneurysms can be used as representative of pre-rupture morphology. Further larger studies in collaboration with other neurosurgical centres to corroborate this view would be helpful.
