Background
Studies have shown that atherosclerotic stenosis is more common in the brain. Intracranial arterial stenosis is a senile brain disease that can cause cerebral ischemia, hypoxia, and infarction to cause different degrees of neurological dysfunction such as hemiplegia, aphasia, hemianopsia, and paresthesia. At present, the treatment methods for intracranial arterial stenosis include drug therapy, surgical operation, pure balloon angioplasty and the like, but all of the methods have respective limitations, and especially the treatment methods for patients with severe stenosis are limited in curative effect. Balloon expandable vascular stents have also been combined with drug therapy, but the adaptability of vascular stents to intracranial vessels has yet to be improved and the surgical risk has yet to be further reduced.
At present, the number of the stents specially used for intracranial vessels is small, and the coronary stent is clinically used for replacing the intracranial arterial stenosis forming operation, because the coronary artery is relatively straight, the soft section of a coronary stent system is short, the naming pressure (the pressure when a saccule reaches a preset diameter) is higher (more than 6 atmospheric pressures), and the intracranial artery is more tortuous than the coronary artery and has a thinner blood vessel wall, the treatment effect is not satisfactory enough, the operation difficulty is large, the risk is higher, and the intracranial arterial restenosis can not be effectively solved (the intracranial stent restenosis is up to 40%). Therefore, there is a medical need for an intracranial vascular stent designed specifically for intracranial vessels, having better flexibility and clinical operation and treatment adaptability.
