History of cerebral revascularization

Cerebral revascularization is constantly being updated and iterated, but there are still many challenges: how to regulate the bypass flow quantitatively, how to reconstruct cerebral artery perforator vessels with diameter less than 0.5 mm, etc.. This paper reviews the birth of revascularization and the development of cerebral revascularization, focusing on the basic principle and innovative technology of cerebral revascularization, application and effect of cerebral revascularization in the treatment of complex intracranial aneurysms, current situation and development trend of cerebral revascularization iteration. The aim is to promote the iteration of cerebral revascularization and its application in the treatment of complex intracranial aneurysms.
