Lower limb arterial stenosis can be treated conservatively, percutaneous balloon angioplasty, thrombolytic therapy, stent intervention, etc., and the appropriate program is chosen according to the actual situation of the patient.
1. Conservative treatment: applicable to patients with mild stenosis and contraindications to surgery. Drug therapy and exercise are the mainstay. Drugs are mainly based on local vasodilatation and analgesia, commonly used prostacyclin, high-dose prostacyclin will appear blood pressure drop, facial flushing and other adverse reactions, bleeding tendency is prohibited. Exercise needs to be developed according to the specific situation, commonly used such as lying leg raising training.
2. Percutaneous balloon angioplasty: through the intervention of the stenosis of a certain degree of expansion, so that the lumen is enlarged.
3. Thrombolytic therapy: mainly applied to acute intravascular thrombosis, after placing the catheter and injecting urokinase for thrombolysis, but if the patient has acute visceral hemorrhage, intracranial hemorrhage, urokinase is prohibited, and patients with severe hypertension should use with caution.
4. Stent intervention: after thrombolysis and angioplasty after the effect is not good, the choice of endovascular stent, support the vascular lumen of the blood vessel to maintain long-term usually.
