Stenting of the arteries in the lower extremities is a common treatment for severe stenosis or even occlusive lesions in the arteries of the lower extremities, and the decision to implant a stent is based on the stenosis of the vessel. Currently, there are three main types of arterial stents in common use: the first is the bare metal stent, which is widely used and is mainly divided into sculpted and braided types. The cost of bare metal stents is generally around 10,000-15,000 RMB. The second type of stent with overlay is relatively expensive, with a general price of about 20,000-25,000 yuan. The third type is the newer type of stent with heparin coating, which is more expensive, generally costing 30,000-35,000 RMB. The specific choice of stent needs to be made during the procedure, taking into account the vascular lesion and the patient’s economic situation, to select the appropriate stent for arterial stenting.
