If the effect of interventional therapy is not obvious, medication and surgical treatment can also be continued. Interventional therapy means that without surgery and without exposing the lesion site, through some tiny channels on the blood vessels and under the guidance of imaging equipment, the lesion site can be treated precisely, and the procedure is characterized by small trauma, safety, simplicity, and effectiveness. Interventional therapy is not suitable for all patients, and the effect of interventional therapy varies from patient to patient. If interventional therapy fails to achieve the therapeutic goal, conservative treatment with internal medicine and surgical treatment can still be used. For example, patients with heart attack can be treated with aspirin and antiplatelet therapy, and bypass surgery can be considered for stenosis. For some tumor patients can also be combined with radiotherapy. Regardless of which treatment method you choose, be sure to ask your doctor for an evaluation first, and then choose the best treatment plan according to the actual situation.
