Combined Internal Maxillary Artery to Middle Cerebral Artery and In Situ Middle Cerebral to Middle Cerebral Artery Bypass for Complex Middle Cerebral Artery Aneurysm: 3-Dimensional Operative Video

Operative Neurosurgery, 2019
Abstract Flow-replacement revascularization and/or flow augmentation surgery may be necessary for safe deconstruction of complex middle cerebral artery (MCA) aneurysms. Roughly 1% to 2% of all MCA aneurysms have angiographic features prohibiting standard microsurgical or endovascular management.
