Vascular interventional techniques have emerged in the last decade as an effective treatment method for vascular diseases, with the advantages of low trauma, low response and fast recovery, as well as targeted characteristics, allowing patients who cannot tolerate surgery and drug-resistant patients to be treated effectively. Vascular intervention is a minimally invasive procedure in which a small incision is made in the skin, a puncture needle is used to enter the vessel, a channel is established, and then a special catheter or guidewire is passed along the vessel channel to the problematic part of the vessel. Stenosis is a systemic disease that commonly includes lower extremity artery stenosis, iliac artery stenosis, renal artery stenosis, coronary artery stenosis, carotid artery stenosis, and intracranial artery stenosis. The procedure varies, but all involve passing a guidewire through the stenotic segment, introducing a balloon catheter through the guidewire, and using the balloon to dilate the stenotic segment, and then deciding whether endovascular stenting is required based on the post-dilatation imaging. After the intervention, oral antiplatelet medication is required, along with blood glucose and lipid control, smoking cessation, and active treatment of the primary disease. At the same time, it is extremely important for patients to perform appropriate exercise after lower extremity arterioplasty to promote recovery.
