Last Updated: September 28, 2018
Both surgical and endovascular therapies can be safe and effective in treating posterior circulation aneurysms; however, there are stronger propensities to treat certain posterior circulation aneurysms by one method or the other based on the different risk profiles of open and endovascular modalities, particularly in perforator-rich and prebulbar locations.
Although the majority of posterior circulation aneurysms are saccular aneurysms, there are higher rates of dissecting pseudoaneurysms and fusiform aneurysms in this vascular territory.
When planning treatment for posterior circulation aneurysms, one should consider the accessibility of the lesion as well as relationship of the aneurysm to the perforating vessels, to the posterior clinoid process, and the necessity/safety of dual anti...
