The middle cerebral artery (MCA) bifurcation is a preferred site for aneurysm formation. Wider bifurcation angles have been correlated with increased risk of aneurysm formation. We hypothesized a link between the presence of MCA aneurysms and the angle morphology of the bifurcation. ⋯ MCA bifurcations harboring aneurysms have significantly larger branching angles and more often originate off the branch with the largest angle. Wider inclination angle is strongly correlated with aneurysm presence, a novel finding. The results point to altered wall shear stress regulation as a possible factor in aneurysm development and progression.

Several endovascular treatment options are available for cavernous carotid aneurysms. We compared pipeline embolization device (PED) versus conventional endovascular treatment in terms of evolution of mass effect, complications, recurrence, and retreatment rate. ⋯ The use of PED should be encouraged, especially in symptomatic patients. We found PED to be associated with less need for future treatment, higher improvement in symptoms rate, and lower rate of complications.

Intraventricular thrombolysis (IVT) is a promising treatment in facilitating intraventricular clot resolution after intraventricular hemorrhage. We examined in-hospital outcomes and resource utilization after thrombolysis in patients with intraventricular hemorrhage requiring ventriculostomy in a real-world setting. ⋯ IVT for intracerebral hemorrhage requiring ventriculostomy resulted in lower inpatient mortality and a trend toward favorable discharge outcome with similar rates of inpatient complications compared with the non-IVT group.
