研究类型:

观察性研究

Study type:

Observational study

研究所处阶段:

研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

利用光学相干断层成像技术(optical coherence tomography,OCT)对药物洗脱支架治疗颅内椎动脉粥样硬化狭窄术后血管及支架内情况进行观察,为药物支架植入术后支架内情况提供早期初步证据,辅助指导后续诊疗策略。  

Objectives of Study:

The objective is to evaluate the condition of blood vessels and stents after the implantation of drug-eluting stents for the treatment of intracranial vertebral atherosclerotic stenosis using Optical Coherence Tomography (OCT). This approach aims to furnish preliminary evidence regarding the condition of stents post-implantation, thereby aiding in the formulation of subsequent diagnostic and therapeutic strategies.
