Ulcers appear in the arterial vasculature because the arterial vasculature, on the basis of atherosclerosis, causes the arterial plaque to fall off and ulcers will appear at the site where the plaque fell off. The endothelium of the vessel is needed for repair, and there is a risk of thrombus formation in this process, also because of the great impact of the blood flow, which makes the blood ulcer larger and larger, forming an intramural hematoma and also a sandwich. The patient will exhibit severe pain, and in this case, overlapping stent isolation is required, which is a stent with a membrane in front of the ulcer to allow blood flow within the stent without impacting the ulcer, and the patient’s painful symptoms will be relieved. If the patient has atherosclerosis, it is important to actively prevent further development of atherosclerosis. If the patient has an ulcer, it is necessary to lower the blood pressure and also to actively prevent atherosclerosis.
