The treatments for restenosis after stenting include medication, interventional therapy, surgical treatment and so on. 1. Drug therapy: It is suitable for patients with mild restenosis, and can strengthen the strength of the existing drugs, such as anti-platelet drug aspirin, statin drug atorvastatin and so on. 2. Interventional therapy: If the degree of restenosis is serious and ischemia occurs, re-interventional therapy, i.e., re-stenting, can be performed, but it is necessary to determine whether the patient can undergo re-interventional therapy. 3. Surgical treatment: it is suitable for patients who are not suitable for re-intervention after restenosis and the degree of restenosis is serious; surgical bypass surgery can be performed, but this method is more damaging to the patients. When restenosis occurs after stenting, it is recommended to go to the hospital in time and obey the doctor’s arrangement. The medication should be prescribed by the doctor.
