Hazards of HIFU knife

Because the number of people suffering from tumors is constantly increasing in modern society, many different methods of treating tumors have been developed in clinical medicine. Among them, HIFU is a relatively popular method of treating tumors in recent years. HIFU uses many precision instruments, making tumor treatment more accurate and precise. But at this time, everyone needs to understand the dangers of HIFU knife.

Indications

1. Liver tumors

Benign and malignant liver tumors.

2. Pancreatic cancer

Pancreatic cancer without jaundice or after jaundice-reducing treatment.

3. Soft tissue tumors

Benign and malignant soft tissue tumors.

4. Uterine fibroids

5. Others

Retroperitoneal or abdominal or pelvic solid tumors with good ultrasound channels.

Contraindications

1. Tumors of air-containing hollow organs, such as the intestines and stomach.

2. Central nervous system tumors.

3. When there is skin ulceration or infection in the treatment area.

4. The skin in the treatment-related area has received radiotherapy of more than 45 Gy.

5. When there is significant calcification of the arterial wall in the channel of ultrasound treatment.

6. Patients with failure of important organs.

7. Patients with severe coagulation disorders.

8. Patients who cannot tolerate appropriate anesthesia.

9. Tumors that cannot be clearly displayed by the mechanical positioning imaging system.

advantage

The main advantages include: no surgery, no bleeding, and no restrictions on tumor size or shape. Generally, a one-time treatment is adopted, and recovery after surgery is quick and the immune system can be activated. There is no radiation or chemical damage, and the problem of tumor insensitivity encountered in radiotherapy and chemotherapy will not occur. The treatment can be repeated, and a planned segmented treatment can be implemented. Radical treatment can be used for early-stage lesions, and palliative treatment can be used for late-stage lesions to effectively reduce the tumor burden. It can also be combined with other treatments such as radiotherapy and chemotherapy and will not conflict with other treatments. In addition, HIFU treatment for breast tumors, bone tumors, and uterine fibroids also has the advantages of preserving the original shape of the breast, preserving the limbs, and preserving the uterus.

The following situations may occur during the HIFU treatment: ⑴ Mild skin burns; ⑵ Adverse reactions during sedation and analgesia; ⑶ Nerve damage; The above risks can be avoided if careful preparation is made before treatment and real-time monitoring is carried out during treatment; Once an adverse reaction occurs, it can almost always be improved, and no serious complications have occurred.
