Stenting of intracranial stenosis is a minimally invasive treatment that is performed by puncturing the femoral artery and implanting a stent into the blood vessel to achieve the therapeutic purpose, which is a more effective treatment method. With the development of modern medicine, the continuous innovation of technological materials, and the continuous improvement of doctors’ skills, the risks of intracranial stenosis stenting have been gradually reduced, and it is a relatively safe treatment. Post-operative risks include: a sudden increase in blood flow in a severely stenotic vessel after stenting can lead to distal vessel rupture, bleeding, or the continued formation of blood clots within the stent due to a poor lifestyle, which can lead to stenosis again and require further treatment, such as balloon dilatation or re-stenting.
