Osteosarcoma stents cannot usually be removed. The stent is a mesh-like metal structure that will be firmly embedded in the blood vessel after implantation. First, the stent requires a lot of pressure during its release and fuses very well with the blood vessel wall, and over time, the stent will be completely covered by the endothelial cells of the blood vessel, and eventually fuses completely with the blood vessel tissue. When the endothelial cells cover the stent completely, the surface of the stent will become very smooth, completely isolated from the blood, only located between the endothelium and the outer layer of the blood vessel, and the blood is not in contact with the stent, so the stent can not be removed, and there is no need to remove. Osteosarcoma scaffolds have the ability to promote osteogenesis and enhance synergistic photothermal therapy against osteosarcoma, and scaffolds have great potential for use in the repair of defects associated with bone tumors. It is recommended that patients should take oral Bay Aspirin, Clopidogrel Hydrogen Sulfate Tablets, Atorvastatin Calcium and other medications as prescribed by the doctor for treatment after osteosarcoma stenting, pay attention to a low-salt and low-fat diet in general, and consult a doctor for review in a timely manner if there is any discomfort.
