Stenting for Severe C7 Stenosis of Internal Carotid Artery (ICA) and Related Literature Review

Intracranial Atherosclerosis (ICAS) is a common cerebrovascular lesion worldwide and an important cause of stroke [1]. Nonmodifiable risk factors include age, gender, and genetics, with age being a key factor and atherosclerosis usually progressive, with no clinical manifestations until middle age. Ischemic Heart Disease (IHD) has increased fivefold among people aged 40 to 60. Before menopause, women are less prone to atherosclerosis than men, and the incidence of atherosclerosis is increased in postmenopausal women [2,3]. The inheritance of various genetic polymorphisms and the accumulation of family risk factors (such as diabetes and hypertension) create multiple conditions for the formation of atherosclerosis [4]. On the other hand, modifiable risk factors, such as smoking, hyperlipidemia, diabetes, and high blood pressure, can be improved by adjusting daily life. Studies have analyzed that white people are prone to extracranial arterial occlusive disease, while Asian, black and Hispanic people have a higher risk of intracranial atherosclerotic disease [1]. Therefore, the prevention of atherosclerotic disease, has been very urgent, to increase publicity, from the source to solve
