Introduction: Aneurysm occur in approximately 3.2% of the population with a mean age of 50 years, a 1:1 gender ratio, and an estimate mortality rate of 70%. Aneurysms develop at branch points with elevated intravascular turbulence and vessel wall shear stress. we aim to compare the efficacy and safety of different surgical treatment modalities for bifurcating intracranial aneurysms.

Methods: A retrospective review of 398 patients who underwent surgical management of a bifurcating aneurysm at Thomas Jefferson University hospital from 2010 to 2020. Aneurysm size, location, modality of treatment, and treatment complications were assessed.

Results: Data analysis is expected to return from the statistician in early to mid-December. Data analysis has not been returned to date.

Discussion: We hypothesize that those treated with endovascular techniques have better outcomes than those who received intracranial clippings. Additionally, we expect that coil embolization will have better results for saccular aneurysms, while balloon assisted stenting or stent assisted coiling of aneurysm will provide better outcomes for fusiform aneurysms. If these hypotheses hold true, then our data will suggest that there are specific surgical treatment modalities that improve patient outcomes based upon aneurysm type.
