Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This project collects multimodal imaging data, including CT perfusion and angiography, to create 3D models of cervical artery stenosis. Computational fluid dynamics and AI analysis are used to assess hemodynamics. By monitoring blood flow, oxygen levels, and evaluating postoperative outcomes, the goal is to tailor surgical approaches for better patient outcomes and improved quality of life.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
There are currently two main surgical approaches for treating severe cervical artery stenosis: carotid endarterectomy (CEA) and carotid artery stenting (CAS). The effects of these two surgical methods on preoperative and postoperative intracranial and extracranial hemodynamic changes, the mechanisms underlying perioperative complications, the establishment of collateral circulation, and long-term prognosis remain unclear. Therefore, researching perioperative risk assessment and clinical efficacy of different surgical approaches is of great significance for patient outcomes.
This project aims to collect multimodal imaging data from patients with cervical artery stenosis, including brain CT perfusion imaging and CT angiography. Using artificial intelligence algorithms, three-dimensional models of cervical artery stenosis will be reconstructed, and computational fluid dynamics will be employed to automatically or semi-automatically analyze the hemodynamic characteristics of patients' carotid arteries. By monitoring cerebral blood flow velocity, local cerebral oxygen metabolism, and assessing postoperative stroke, ischemia-reperfusion injury, and collateral circulation both intracranially and extracranially, precise evaluations will be conducted.
Based on individual patient characteristics, the surgical approach can be optimized to prevent cerebral ischemia-reperfusion injury, improve clinical prognosis, and enhance the quality of life for patients.
