Double lower extremity venous thrombosis, which may be caused by lower extremity braking, slow blood flow and hypercoagulable state of blood, can be treated by physical therapy, medication and improved diet. 1. Lower limb braking: For example, orthopedic patients, patients with traumatic injury or long-term bedridden patients have less activity in lower limbs and infrequent muscle contraction, in which case the blood flow is slow and blood clots are easy to be formed. You can elevate the affected limbs to promote the venous blood return of the lower limbs, and you can use some diuretics, such as furosemide, hydrochlorothiazide and so on, according to the doctor’s instructions. 2. Slow blood: If the blood is thick and sticky, high viscosity, coupled with dietary inattention, blood viscosity will lead to slow blood flow. Slow venous blood flow will cause blood stagnation, creating conditions for thrombosis. Usually should pay attention to light diet, local hot compresses, massage, appropriate exercise. You can take aspirin, clopidogrel and other drugs as prescribed by the doctor. 3. Hypercoagulable state of blood: generally refers to the dysregulation of the body’s hemostasis, coagulation and anticoagulation system caused by pathological changes in blood vessels, blood, and blood flow components, and has a variety of blood changes that easily lead to thrombosis. Drugs such as atorvastatin and epothilone tablets can be used as prescribed by the doctor. Once the double lower extremity venous thrombosis occurs, the patient must go to the regular hospital for consultation and treatment under the guidance of professional doctors to avoid delaying the condition.
