Intracranial⁃intracranial bypass for the treatment of complex intracranial aneurysms: technical advances and surgical experience

Abstract

Intracranial-intracranial bypass is a crucial treatment for complex intracranial aneurysms, as it not only achieves aneurysm eradication but also ensures perfusion to the bypassed vascular territory. To ensure bypass vessels patency and postoperative neurological recovery in patients with aneurysm, it is necessary to consider multiple characteristics of the aneurysm, donor artery and recipient artery. This comprehensive evaluation enables the selection of appropriate surgical decisions and bypass techniques. In recent years, with the advancement of intracranial-intracranial bypass, several new options including donor artery and recipient artery, anastomosis techniques, graft vessels, and auxiliary techniques have been added for neurosurgeons to choose from. This review aims to introduce the technical advances, surgical experience of intracranial - intracranial bypass for complex intracranial aneurysms, with the intention of facilitating clinical application of intracranial-intracranial bypass.
