Vascular stenosis can be divided into, physiological vascular stenosis and pathological vascular stenosis. 1, physiological vascular stenosis, often caused by less physical labor or physical exercise, can be improved by increasing physical labor or physical exercise, during exercise the arteries expand, blood supply increases leading to increased venous return, the blood vessels will have different degrees of expansion to improve the symptoms of vascular stenosis. 2, if the condition is pathological, often caused by atherosclerosis, then surgery or endovenous treatment, stent implantation should be performed to restore local blood flow and allow blood flow to reach the blood supply area of the vessel. , if the condition is pathological, often caused by atherosclerosis, then surgery or endoluminal treatment, stent implantation should be performed to restore the local blood flow and allow blood flow to reach the blood supply area of the vessel, so that the patient’s symptoms can be reduced.
