Arteriography is a minimally invasive treatment and examination method. It mainly uses the natural continuous pipeline of the blood vessels to make an access to the superficial vessels, reaches the lesion site by intervention, observes the target lesion site according to its treatment needs, and is able to provide good imaging data for subsequent interventional treatment. It is the gold standard in the examination of arterial disease by injecting contrast into the vessel to show the course of the vessel, the blood supply and the lesion of the target vessel, and is able to clearly see the length, location and degree of stenosis of the vessel. In case of dilated disease, the parameters of the aneurysm can also be seen, providing the easiest, most intuitive and valuable imaging information for subsequent treatment. In addition, on the basis of arteriography, balloon dilation and stenting can be performed to treat arterial stenosis, occlusive and dilated disease.
