How to treat venous thrombosis of lower limbs?

The treatment of venous thrombosis of lower limbs depends on the specific situation of patients. For patients with thrombosis, anticoagulant therapy should be given first to prevent the thrombus from developing further, and then thrombolytic therapy should be given, including drug thrombolysis, mechanical thrombolysis, traditional bloodletting and other different ways. For patients with chronic thrombosis, stent and drug balloon dilatation should be selected according to the patient's vascular condition. The causes of varicose veins of lower limbs are related to the types of patients. Primary superficial varicose veins of lower limbs are caused by valve dysfunction of great saphenous vein or small saphenous vein of lower limbs; Congenital arteriovenous fistula is due to congenital dysplasia, which makes arterial blood directly enter the venous system, leading to an increase in venous blood flow and oxygen saturation. In addition, abnormal deep vein function can also cause varicose veins of lower limbs.
