Surgical treatment of carotid artery stenosis

  Stroke is the third leading cause of death today and the leading cause of disability in adults. Carotid artery stenosis is the most common cause of ischemic stroke events.  The main preventive measures are: 1) drugs, 2) endovascular stenting, and 3) carotid endovascular debridement.  Numerous clinical trials have demonstrated that carotid endarterectomy is effective in preventing stroke in both symptomatic and asymptomatic patients with carotid stenosis. About 200,000 carotid endarterectomies are performed each year in the United States, but only a few hundred are performed in China, which is disproportionate to the size of our population.  Several randomized controlled trials in the 1980s and 1990s have demonstrated that carotid endarterectomy is the “gold standard” for stroke prevention compared to medical therapy; comparisons with stenting are under investigation.  According to data, 200,000 carotid endarterectomies (CEA) are performed each year in the United States. The procedure is safe, economical and effective. The many advantages of this technique should make it particularly suitable for the Chinese situation. However, it is strange that this technique is still not widely available in China.  The reasons for this are: the limited number of patients attending the clinic and, more importantly, the lack of physicians in terms of patient intake and knowledge dissemination. The latter is especially true.
