The first is the diagnosis of carotid artery stenosis, because the symptoms of carotid artery stenosis are widespread, and the more common symptoms include dizziness, headache, weakness of the limbs, drowsiness, etc. As the condition gradually worsens, symptoms such as vision, memory, and mental decline will appear. Second, the treatment of carotid artery stenosis may vary in the treatment of different degrees of the condition. First, the diagnostic criteria of carotid stenosis Carotid stenosis mostly occurs in middle-aged and elderly people, and if symptoms such as dizziness, weakness and drowsiness continue to appear frequently in ordinary life, it is necessary to receive timely examination at the hospital. Carotid artery stenosis can be detected by MRI, CTA
MRA, etc. Generally, a stenosis of less than 50% is defined as mild carotid stenosis, 50%-70% is defined as moderate carotid stenosis, and more than 70 is defined as severe carotid stenosis. Treatment of carotid stenosis Mild carotid stenosis can be treated with medication, and it is possible to recover by maintaining good living habits, as well as a relaxed spirit and happy mood, and regular review at the hospital. The treatment of moderate to severe carotid stenosis is more troublesome and requires surgical intervention to unblock the narrowed or occluded carotid artery. Currently, the surgery that can completely cure carotid stenosis is carotid endarterectomy, which is a complex operation and requires precise medical skills. Carotid endarterectomy has been performed for nearly 70 years since its inception in the 1950s and has become very common in Western countries, but not yet in China. Currently, only a few tertiary hospitals in first-tier cities are able to perform the procedure.
