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.

Randomized Controlled Trial
Lacunar strokes in patients with diabetes mellitus: risk factors, infarct location, and prognosis: the secondary prevention of small subcortical strokes study.
Diabetes mellitus is an independent risk factor for lacunar strokes. Few data are available regarding patient features, infarct location, and recurrent vascular events for patients with diabetes mellitus with lacunar stroke. ⋯ http://www.clinicaltrials.gov. Unique identifier: NCT00059306.
