Carotid artery stenosis
At the end of 2009, the Ministry of Health announced that the annual incidence of stroke in China has reached 219/100,000 people, with about 1.5-2 million new cases each year, 80% of which are ischemic strokes, which have become the first cause of disability and death. Extracranial carotid and vertebral artery stenosis is an important cause of ischemic stroke.
Carotid artery stents (CAS) are minimally invasive, with a cumulative perioperative 30-day mortality and stroke rate of 3.3-7.6%, which is essentially comparable to classical carotid endarterectomy (CEA), and can effectively prevent and treat recurrent stroke with reliable long-term outcomes. 1.2% require re-intervention. The advantages of CAS are even more pronounced in surgically treated high-risk patients (high-grade stenosis, severe cardiopulmonary disorders that cannot tolerate surgery, stenosis after CEA or radiotherapy, postoperative restenosis, etc.). Indications for carotid atherosclerotic stenosis: (1) asymptomatic stenosis ≥ 70%, symptomatic stenosis ≥ 50%; (2) recurrent symptoms of plaque instability with intensive drug therapy.

The opening of the vertebral artery is a good site for atherosclerotic stenosis occlusion, which can cause dizziness and nausea, but a considerable part of the clinical misdiagnosis and mistreatment of thought cervical spondylosis, when the lesion involves the dominant side or isolated system often leads to serious disability and death of patients.
In recent years, our department has completed hundreds of cases of stenting for extracranial artery stenosis, with a success rate of ≥97% and a severe disability and death rate of ≤2%, and has established a standardized operation procedure.
More pictures of the cases will be shown in the “Typical Cases” section, which is worth waiting for.
