Introduction The quickest path possible is typically taken when treating brain aneurysms. This access is carried out through the internal carotid artery in situations where there is an anterior circulation aneurysm. When the internal carotid artery is occluded, the challenge is to treat anterior circulation aneurysms endovascularly and take the quickest route possible.
In cases of aneurysms of the posterior circulation and lack of access from the vertebral arteries, it is possible to treat them also through the communicating arteries from the access from the internal carotid arteries.
Aim of Study The purpose of the study is to show that a brain aneurysm can still be accessed even in the absence of the shortest path.
Methods In the presentation, we show several cases of such aneurysm embolization procedures of access through the communicating arteries, where it is possible to bypass obstacle due to the arterial circle of the brain (Willis).
Results In the presentation, we demonstrate several cases of such aneurysm embolization procedures as well as additional issues that could develop and potential complications.
Conclusion Although it may be difficult for the operator, it is sometimes possible to perform cerebral aneurysm embolisation procedures using the available arteries connecting the circulations.
