Liver RF, Image-guided microwave ablation of lung tumors has revolutionized the treatment of various cancers, especially soft tissue tumors, in recent years. The techniques used in this method are more tolerable for patients and have fewer side effects. Most of these techniques require modern medical equipment and high levels of expertise. Primary or metastatic lung tumors, or inoperable lung tumors, can be treated using interventional radiology methods.
Symptoms of lung tumors
Lung tumors, both benign (non-cancerous) and malignant (cancerous), can cause a variety of symptoms. These symptoms can vary depending on the size and location of the tumor, as well as the individual’s overall health.Here are some common symptoms of lung tumors:
- Cough: This is often the first and most common symptom. The cough may be persistent, productive (producing mucus), or bloody.
- Shortness of breath: Difficulty breathing, especially during exertion, can be a significant symptom.
- Chest pain: Chest pain can vary in intensity and may worsen with deep breaths or coughing.
- Wheezing: A whistling sound that occurs during breathing.
- Hoarseness: Changes in voice or difficulty speaking.
- Fatigue: Feeling unusually tired.
- Weight loss: Unexplained weight loss can be a sign of lung cancer.
- Loss of appetite: Diminished appetite or difficulty eating.
- Fever: Although less common, fever can sometimes occur.
Novel Interventional Radiology Treatments for Lung Tumors
Recent advancements in interventional radiology have introduced innovative and less invasive methods for treating lung tumors. These techniques offer patients a range of treatment options that complement traditional approaches like surgery, chemotherapy, and radiation therapy.
Key techniques include:
- Superselective embolization: This minimally invasive procedure involves blocking the blood vessels that supply the tumor. By cutting off its blood supply, the tumor is deprived of the nutrients it needs to grow and can shrink.
- Microwave ablation: This technique uses high-frequency radio waves to heat and destroy lung tumors. It’s particularly effective for smaller tumors and can be used as a primary treatment or in conjunction with other therapies.
- Microwave ablation (MWA): Similar to the previous method, MWA involves inserting an antenna into the tumor to deliver microwave energy. This heats and destroys the tumor cells.
Benefits of these techniques:
- Minimally invasive: These procedures are less invasive than traditional surgery, often requiring only local anesthesia.
- Targeted treatment: The treatments can be directed specifically at the tumor, minimizing damage to healthy tissues.
- Effective for various tumor types: Both primary and metastatic lung tumors can be treated with these methods.
- Complementary therapy: These techniques can be used in conjunction with other treatments, such as surgery, chemotherapy, or radiation therapy.
Overall, interventional radiology offers patients with lung tumors a variety of less invasive treatment options, improving outcomes and quality of life.

Liver RF> Pre-procedure:
- After admission and paperwork, initial vital signs will be monitored, including blood pressure, heart rate, and oxygen saturation.
- The targeted area will be sterilized and the patient will be sedated under CT or fluoroscopy guidance to ensure comfort and painlessness during the procedure.
Liver RF > Procedure:
- The procedure typically takes around 40 minutes.
Liver RF > Post-procedure:
- The patient will be transferred to the recovery room for monitoring of vital signs for approximately 30 minutes.
- If follow-up procedures are needed, the patient will be informed of the next appointment schedule before discharge.
Liver RF> Post-procedure care:
- Patients can take regular pain medications at home.
- Light meals can be consumed after an hour.
- Avoid driving for 24 hours.
- Avoid strenuous activity for 24 hours.
- Avoid sudden changes in position, such as going from lying down to standing, for 24 hours.
Liver RF> Potential short-term side effects:
- Mild pain at the procedure site
- Dizziness upon standing
- Fever above 38 degrees Celsius
- Redness, swelling, or severe pain at the procedure site
- Severe headache
- Bleeding from the procedure site
