Microsurgical Partial Trapping for the Treatment of Complex Vertebral Artery Aneurysms
Keywords:
complex cerebral aneurysm, unclippable cerebral aneurysm, vertebral artery aneurysm, vertebral artery dissecting aneurysm, partial trapping, microsurgeryAbstract
Treating complex cerebral aneurysms presents a significant challenge and lacks a well-established protocol. Most aneurysms cannot be directly clipped at the neck while preserving the parent artery. Often, sacrificing the parent artery is necessary to fully obliterate the aneurysm. The two most commonly employed techniques are complete trapping and partial trapping. This article seeks to review the partial trapping technique for addressing complex vertebral artery aneurysms, including the mechanisms behind aneurysm thrombosis, as well as the advantages and limitations of this approach.
