Cerebrovascular diseases are very common in our life, and carotid stenosis is a typical cerebrovascular disease, which mostly occurs in some middle-aged and elderly people. After the narrowing of the carotid artery, the blood from the human heart cannot be successfully transported to the human brain, which will cause more serious problems, such as cerebral infarction and brain death, so patients must pay attention to it. Carotid artery stenosis is a powerful health killer, and every patient should be highly alert, put treatment in the first place, and go to a regular hospital for treatment at the first time. At present, the clinical treatment of carotid stenosis mostly takes two methods: medication and surgery, but medication only works for mild carotid stenosis, but it is ineffective for moderate to severe carotid stenosis, and patients are recommended to go to regular hospitals for surgery. It is understood that carotid endarterectomy is the most effective treatment for moderate to severe carotid stenosis. Does carotid endarterectomy require craniotomy? Many patients worry about this issue because they are afraid to do the surgery easily because they are worried that it is too risky. In fact, there is no need to be afraid, carotid endarterectomy is very safe, the procedure is performed under a microscope and is highly safe. Carotid endarterectomy is performed on the patient’s neck, where the patient’s carotid artery is located, the distal and proximal carotid arteries are temporarily clamped, and then the carotid artery is incised and the diseased intima is peeled off and removed to restore the normal size of the internal diameter. Carotid endarterectomy takes only 1-2 hours and the patient can return to normal life soon after the procedure, making it an ideal technique for treating carotid stenosis.
