Brief Summary:
Extracranial-intracranial arterial bypass, including anastomosis of the superficial temporal artery to the middle cerebral artery and indirect bypass, can help prevent further ischaemic attacks in patients with Moyamoya disease (MMD). However, there is no established standard for the selection of the recipient vessels. In most situations, surgeons choose the recipient vessels with their own experiences. Intraoperative Indocyanine green (ICG) angiography using Flow800 software and multimodal neuronavigation can be used to assess the real-time cerebral blood flow velocity and perfusion of local brain tissue for better selection of the recipient vessels. Thus the aim of this study is to to determine whether direct bypass surgery combined with multimodal neuronavigation is superior to traditional direct bypass procedure alone in adult ischemic MMD patients.
Detailed Description:
There are no effective medical therapies for moyamoya disease. Through the provision of collateral pathways, surgical revascularisation is the most successful therapy to improve cerebral haemodynamics, and to reduce the risk of subsequent stroke. Surgical procedures for moyamoya disease can be classified into three categories: direct bypass, indirect bypass, and combined bypass. Although surgeons have their own experience choosing the recipient vessels,no standard has been established based on a worldwide consensus.
Intraoperative ICG angiography using Flow800 software and multimodal neuronavigation (structure combined with perfusion MRI sequence) can be used to assess the real-time cerebral blood flow velocity and perfusion of local brain tissue, which is contribute to choose a recipient vessels with relative low cerebral blood flow velocity and perfusion.
Therefore,the PBM study in our institution is designed to compare the direct bypass surgery with multimodal neuronavigation with traditional direct bypass procedure alone in preventing any ischemic event afterwards after cerebral revascularization surgery in adult ischemic MMD patients.
