Drug balloon treatment of vascular blockage is clinically more effective, can improve the patient’s blood flow function and improve the quality of life. The mechanism of drug balloon placement is to place a balloon in the patient’s narrow blood vessels, stretching or rupturing the plaque and connective tissue fibers in the intima and mid-media, compressing plaque and thrombus, compressing the medial layer, the redistribution of plaque or thrombus on the inner surface of the artery, and overstretching of the artery, and at the same time because of the placement of the balloon, the diameter of the lumen increases, the tension of the vessel wall decreases, and distal tissues are able to get sufficient blood supply. However, human blood vessels are elastic and prone to retraction, which may result in entrapment tear or luminal narrowing, affecting the therapeutic effect. Balloon angioplasty with stent implantation can further enhance the effect of vascular occlusion. We recommend you to go to the hospital to make a reasonable treatment plan according to your condition.
