Abstract: This chapter reviews the clinical decision-making regarding ruptured basilar tip aneurysms. Basilar tip aneurysms can present formidable challenges for microsurgical clipping due to their less-accessible location, difficulties associated with proximal control, their variable height, and the presence of critical thalamoperforating vessels at their neck. Accordingly, ruptured basilar tip aneurysms are often treated using endovascular techniques. Because of the morphology of the origin of these aneurysms at the basilar bifurcation, adjunctive treatment with balloon or stent assistance is often required. Preservation of the major outflow branches in this region is also critical to a good outcome. Careful monitoring post-operatively is needed for complications of thromboembolism or late complications of coil compaction and regrowth.
