On June 28, 2011, the medical group of Professor Wang Tao of the First Affiliated Hospital of Inner Mongolia Medical College of Neurosurgery successfully performed carotid endarterectomy (CEA) on a 74-year-old patient with severe carotid artery stenosis, marking the first case of CEA in 2005, the Department of Neurosurgery has completed a total of 100 cases of the procedure, both in terms of quantity and quality, and has gradually stepped into the leading position in the field of neurosurgery in China. In terms of quantity and quality, it has gradually entered the leading position in the field of neurosurgery in China. Carotid artery stenosis is one of the most important causes of cerebral infarction, and carotid endarterectomy (CEA) is the internationally recognized gold standard for treatment of carotid stenosis and prevention of cerebral infarction. As our country is aging, the number of such patients is increasing. Patients mostly present with intermittent dizziness, blackness in front of the eyes, transient cerebral ischemic attack (TIA) or recurrent luminal infarction, etc. Screening is as simple as an outpatient carotid ultrasound, and if the stenosis rate due to plaque is greater than 50%, further head and neck CTA at the neurosurgery department is sufficient to confirm the diagnosis. The 100 cases of CEA completed at the hospital also included a large number of high-risk and complex carotid stenoses, such as ultra-advanced patients over 80 years old, occlusion of one side of the stenosis on the opposite side, in-stent restenosis, internal carotid artery occlusion, occlusion of the entire common carotid artery, carotid thrombosis, sediment-like plaque, traumatic carotid occlusion, thread-like signs, etc. More than 1/3 of these patients had combined diabetes or coronary heart disease, hyperlipidemia, and more than one half of them had combined This makes the surgery extremely difficult. This group involved standard CEA, external CEA, patching, intraoperative diversion, stapling and other techniques, and the patients came from inside and outside the region. Because of the low cost, true efficacy and satisfactory postoperative review images, more and more patients have accepted this surgery, and 33 cases were carried out from January to June 2011 alone, and the influence in China has increased, with many presentations and exchanges or invited lectures at domestic and international neurosurgery congresses. In recent years, the neurosurgery department of the hospital has been actively carrying out new techniques and operations, introducing preoperative discussion and postoperative evaluation system, deepening microscopic and microinvasive concepts, and improving the quality and difficulty of surgery.
