Yesterday, I performed a carotid endarterectomy. The patient, Wang, is a relative of Dr. Li of our hospital. Last year, a physical examination revealed that the right carotid artery was 75% stenosed, and Dr. Li found me, and I performed a right carotid endarterectomy on Wang last year, which is to remove the hardened and thickened intima and plaque together. Carotid artery is the main blood vessel supplying the brain, carotid artery stenosis may cause insufficient blood supply to the brain on the one hand, on the other hand, what causes carotid artery stenosis is sclerotic plaque, if these plaques fall off to the brain, it can lead to brain infarction, about 40% of brain infarction is caused by carotid artery stenosis. The neurology department of our hospital admits the most patients with cerebral infarction in the city, and many patients with cerebral infarction have difficulty staying in the hospital because of the tight bed space. However, some people are reluctant to operate or afraid of surgery after finding carotid stenosis and do not treat it in time. In fact, carotid endarterectomy has been proven to be effective in preventing cerebral infarction by domestic and foreign studies, and the surgery is not very traumatic. After receiving surgical treatment, cerebral infarction may not occur again, reducing the burden on children and saving them much trouble. We all know that we have to remove the tumor in time, and we should also treat carotid stenosis in time, and we have to do it when we have to operate. Otherwise, once a cerebral infarction occurs, even hospitalization is difficult, it is likely to hemiplegia, aphasia, dementia, loss of self-care ability, not to mention their own pain, how much trouble for the children ah! Dr. Xing, the doctor in charge, introduced him to the dangers of carotid stenosis, and although he did not feel any discomfort yet, he gladly accepted the surgery. After the surgery last year, Wang recovered very well without any complications, and he was very happy and praised Dr. Xing and me for our good technique. This time, when he came to the hospital for a review, the right carotid artery flowed very well, but it was found that the left carotid artery was 90% stenosed. He came to the hospital again, and Dr. Xing was still in charge of the treatment. He trusted me so much that he still asked me to operate on him, and I was so happy that I performed the left carotid endarterectomy for him again yesterday morning, and the operation was successful again. Old Wang is a brave person, smart and cheerful. He accepted the surgery optimistically and openly in order to improve the quality of life, and such an old man deserves admiration. Middle-aged and elderly people, if carotid artery stenosis is detected by physical examination, it should still be treated actively. For patients who need surgical treatment, in addition to carotid endarterectomy, stentoplasty is also an option depending on the situation.
