Blood normally flows rapidly through the blood vessels, the arteries supply blood to the tissues and organs of the body, and venous blood flows back to the heart. If the blood coagulates, that is, a thrombosis, there is an abnormal situation in which the arteries are unable to supply blood, and the venous blood is unable to flow back. If the blood clots, the arteries cannot supply blood and the veins cannot return blood to the heart, then there will be an abnormality. Arteries can not supply blood will appear tissue, organ necrosis, light amputation, serious death. Traditional treatment: drug thrombolysis, the effect is slow, only for fresh thrombus. Drug thrombolysis is contraindicated for patients with high blood pressure, blood diseases, post-surgery and other conditions that may trigger bleeding. Interventional therapy: Thrombolytic drugs are injected directly into the thrombus through catheter to dissolve the thrombus, or the thrombus is removed through rotary catheter, or the thrombus is crushed through intravascular ultrasound, and then sucked out through suction catheter to quickly remove the thrombus, etc. These methods have good efficacy and can be used only for fresh thrombus. These methods are effective, quick, minimally invasive, safe, and have few side effects, and have now become the preferred treatment for vascular diseases. Traditional Chinese medicine treatment: After surgery, Chinese medicine can be used to recognize and treat the symptoms, or to warm Yang, or to activate blood, or to replenish qi, and to implement medicinal bath and moxibustion, so that the efficacy of Chinese and Western medicine is more guaranteed.
