During the recovery period of deep vein thrombosis, the following points need to be achieved, and the thrombosis can be completely recovered without leaving sequelae. 1, adhere to the regular, sufficient amount, full course of oral anticoagulant drug therapy. Warfarin at the standard dose PT 20-30 seconds, INR2-3, the international recommended course of treatment is six months to a year, generally every three months to review the ultrasound, to see the thrombus re-circulation, recovery, the thrombus completely through the open and then take about 3 months is better. If there is a history of surgery, pregnancy, childbirth, etc., half a year to one year of anticoagulation is usually enough after the cause is removed. Some patients need a comprehensive screening of thrombotic indicators to see if they have thrombophilia-prone factors, such as antiphospholipid antibody syndrome, protein C/S deficiency, and positive lupus antibodies, with these conditions requiring lifelong administration. In between, pay attention to check the coagulation index and notice any black stool, gum bleeding, etc. 2.Fiber-lowering thrombolytic drugs that promote thrombus recanalization. Such as earth kinase, vein Shu Tong granules, etc., through the fibrin-lowering effect, can open the blood vessel early. 3.Increasing the elasticity of veins and contracting venous vascular drugs, such as Mai Zhi Ling, Diosmin tablets, calcium hydroxybenzene sulfonate dispersible tablets, etc., can effectively prevent post-thrombotic syndrome and reduce leg swelling and hyperpigmentation. 4, insist on wearing medical secondary compression elastic stockings: elastic stockings can effectively prevent the recurrence of venous thrombosis in the lower limbs and reduce the possibility of death from pulmonary embolism because they can significantly improve the venous blood flow stagnation in the lower limbs and promote venous blood reflux. It can also relieve or reduce the swelling of lower limbs. 5.It is recommended to pay more attention to rest and proper exercise, and activity within half an hour is better. 6.Take a light diet as the mainstay, drink more water, eat more green vegetables and fruits, and avoid spicy and stimulating food!
