研究目的:

以颈内动脉颅外段粥样硬化性狭窄( carotid artery atherosclerotic stenosis, CAS)患者为研究对象,通过术中 DSA 影像进行解剖学狭窄分析的同时,评价功能学指标:血流储备分数(Fractional Flow Reserve,FFR) 和定量血流分数(Quantitative Flow Ratio,QFR);探讨基于 DSA 进行生物力学指标径向壁应变率(Radial Wall Strain ,RWS)评估斑块稳定性以及对标高分辨 MRI管壁成像和 CTA 斑块能谱分析,以期建立经动脉粥样硬化性狭窄多维度技术和评价体系的建立。  

Objectives of Study:

Patients with atherosclerotic stenosis of the extracranial segment of the internal carotid artery (CAS))were used as the study subjects, and the anatomical stenosis was analyzed and evaluated by intraoperative DSA images Functional indicators invasive FFR(Fractional Flow Reserve,FFR) and non-invasive QFR(Quantitative Flow Ratio,QFR); In addition, we want to compaire the biomechanical index (Radial Wall Strain ,RWS) based on DSA and high-resolution MRI tube wall imaging and CTA plaque spectroscopy analysis.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

每个入选病例由研究者填写。所有病例由电子数据采集系统 (EDC) 进行数据采集,所有数据由临床监查员审核后提交数据管理员进行数据管理 为了增加干预的安全性,试验将由一个数据安全监测委员会 (Data SafetyMonitoring Bord,DSMB) 进行监督。DSMB 通过详细审查所有临床及安全性终点事件来评估研究干预的安全性,保障患者在参加结局研究期间的利益,同时还负责审查临床研究的总体实施情况。如果发现了不可逆转的安全问题, DSMB可能会建议对方案进行修改。但本研究不设立安全性停止终点。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Each selected case was filled in by the investigator. All cases are collected by the Electronic Data Acquisition System (EDC), and all data are reviewed by the clinical monitor and submitted to the data manager for data management To increase the safety of the intervention, the trial will be supervised by a Data Safety Monitoring Bord (DSMB). The DSMB assesses the safety of the study intervention through a detailed review of all clinical and safety endpoint events, safeguarding the patient's interests during the outcome study, and is also responsible for reviewing the overall implementation of the clinical study. If an irreversible security issue is discovered, the DSMB may recommend modifications to the protocol. However, there was no safety discontinuation endpoint in this study.
