Study Population

Patients undergoing vascular recanalization surgery due to stroke

You may qualify if:

• All enrolled patients were diagnosed with clear head and neck artery stenosis and a risk event after head and neck revascularization;
• Location of lesion: origin of internal carotid artery, bifurcation of internal and external carotid arteries;
• Patients with symptomatic head and neck artery stenosis and dangerous events after head and neck blood flow reconstruction, and with a degree of stenosis ≥ 70% on non-invasive examination or stenosis ≥ 50% found on angiography;
• Asymptomatic head and neck artery stenosis and risk events after head and neck revascularization, with a degree of stenosis ≥ 70% on non-invasive examination or stenosis ≥ 60% found on angiography;
• Asymptomatic head and neck artery stenosis and dangerous events after head and neck blood flow reconstruction, with a non-invasive examination of stenosis degree less than 70%, but angiography or other examinations indicate that the stenosis lesion is in an unstable state;
• Symptomatic head and neck artery stenosis and risk events after head and neck revascularization, non-invasive examination of head and neck artery stenosis and risk events after head and neck revascularization are 50% to 69%;
• Sign the project informed consent form

You may not qualify if:

• Patients with poor overall condition and intolerance to general anesthesia;
• Patients with mental illness or severe mental illness;
• Severe respiratory system diseases;
• Pregnant and lactating women;
• Participating in another clinical study;
• Patients with advanced tumors or those who are expected to die within one year;
