Lower extremity vascular embolism is an acute onset disease that generally occurs in the arteries (in the veins generally known as thrombosis). Treatment includes surgical treatment, interventional therapy and drug therapy: 1, surgical treatment: lower extremity arterial embolism is generally acute onset of disease, patients with obvious symptoms, such as pain, pallor, weakness, numbness, etc., will generally seek emergency treatment. At this time in the limb of the embolism to be urgent incision thrombectomy, surgery has a certain risk, often able to save the limb, to avoid amputation. When irreversible necrosis has occurred in the tissue, amputation of different planes should be considered. 2, interventional therapy: that is, endovascular treatment, including catheter thrombolytic therapy, balloon dilatation stent implantation surgery or laser ablation surgery. It is generally applicable to patients with subacute or chronic lower limb arterial embolism, and acute ischemia can be used at discretion according to specific circumstances. 3, drug therapy: including anticoagulant drugs, thrombolytic drugs, arterial dilatation therapy and improve microcirculation and other symptomatic drugs. Anticoagulants include heparin, low molecular heparin, warfarin and new anticoagulants. Thrombolytic drugs include urokinase, fibrinolytic enzyme, tissue-type fibrinogen activator (t-PA) and so on. Treatment of lower extremity arterial embolism can be drug therapy combined with surgery.
