The pathogenesis of intracranial aneurysms (IAs) is multifactorial and includes genetic, environmental, and anatomical influences. Hemodynamic stress plays a particular role in the formation of IAs, which is conditioned by the geometry and morphology of the vessel trees. To identify image-based morphological parameters that correlated with the formation of basilar ...

Selected intracranial aneurysms still require parent artery occlusion. Although such occlusion is usually performed proximal to the aneurysm, in rare instances it may be difficult or impossible to access the proximal parent artery. To describe the use of parent artery sacrifice distal to the aneurysm (distal outflow occlusion) in the ...

Cerebral vasospasm following aneurysmal subarachnoid hemorrhage (aSAH) results in significant morbidity due to ischemia. Subarachnoid hematoma evacuation during aneurysm clipping reduces the incidence of vasospasm. However, studies comparing endovascular coiling with open clipping have reported similar rates of spasm. We addressed the question of how coiling produces similar (if not ...
