Rethinking Cerebral Bypass Surgery.

Despite the evolution of indications, cerebral bypass remains an important treatment for selected patients with moyamoya disease, steno-occlusive cerebrovascular disease, complex aneurysms, and tumors. Ongoing advancements in patient selection and recent strategic, technical, and technological innovations are facilitating more tailored constructs with lower complication rates and continue to reshape the field. The consolidation of cerebral bypass to specialized centers will likely continue as the complexity of both the pathologies requiring treatment and the revascularization constructs performed increases.
