The common risks of interventional therapy include allergy to contrast media, blood vessel injury, and catheter guide wire breakage. 1. Allergy to contrast agent: If the patient is allergic to contrast agent, the patient’s skin may have uncomfortable symptoms, such as redness, swelling, itching, etc., and the patient may also have a runny nose, coughing, etc., and in severe cases, it may even lead to loss of consciousness. 2. Vascular injury: the catheter wire catheter moving in the blood vessel, may touch the blood vessel wall, which may lead to blood vessel injury or even blood vessel rupture. 3. Broken catheter wire: The catheter wire catheter may be broken because it is moving in the blood vessel, which may lead to unplugging. Any treatment method has certain risks, and different treatment methods have their own advantages and disadvantages. Interventional therapy is less risky than traditional surgical treatment, and while many conventional surgical treatments require general anesthesia, interventional therapy only requires local anesthesia. Interventional therapy should be performed in a regular large hospital, which is more experienced and can provide better and more guaranteed medical services to patients.
