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.

摘要：

颅内-颅内血管搭桥术是治疗复杂颅内动脉瘤的重要方法，根治动脉瘤的同时确保桥血管供血区灌注。为保证桥血管通畅和术后神经功能恢复，需综合动脉瘤、供体和受体动脉特征，采取合适的手术策略和搭桥方式。近年随着颅内-颅内血管搭桥术的发展，增加了新的供体和受体动脉、吻合方式、移植血管和辅助技术供神经外科医师选择。本文旨在回顾颅内-颅内血管搭桥术治疗复杂颅内动脉瘤的技术特点和手术策略，并对新发展的技术进行总结，以期促进颅内-颅内血管搭桥术的临床应用。
