Chemoembolization of liver tumors
Chemoembolization
Chemoembolization is a type of chemotherapy performed through angiography. This method allows for the direct injection of chemotherapy drugs into the arteries supplying the tumors, enabling the medication to reach the tumor at a higher concentration while reducing the side effects of the drug.
Advantages of Chemoembolization
The possibility of achieving a significantly higher concentration of the drug within the tumor (approximately 10 to 25 times more than conventional chemotherapy).
– Prolonged duration of therapeutic effect (a significant amount of the drug remains detectable in the liver up to one month later).
Stopping tumor growth due to the blockage of the tumor’s feeding artery and direct chemotherapy.
Fewer side effects in direct chemotherapy.
It should be noted that the chemoembolization method is typically used as an adjunct to chemotherapy for controlling liver lesions and will not replace systemic chemotherapy.
Necessary Preparations for the Procedure
Fasting for approximately 6 hours prior to the procedure.
Bathing and removing pubic hair in the groin area
Carrying documents related to the illness.
– Perform a blood coagulation test
The presence of one companion for administrative procedures.
Intervention Clinics
The interventional clinics at pardis noor comprehensive imaging centers utilize advanced equipment and a specialized team to provide minimally invasive medical treatments with high precision and safety.
Necessary Preoperative Examinations
It is necessary for your liver function to be evaluated by the center’s specialist physician.
If you have heart disease or diabetes, be sure to inform your doctor so that the necessary measures can be taken.
If you are taking medications such as warfarin, aspirin, or Plavix, be sure to inform your doctor.
Postoperative Symptoms
– The sensation of pain following this procedure, which is typically alleviated with pain relievers depending on the location and extent of the lesion.
Mild fever, which may persist for up to a week after chemoembolization, is expected. To prevent nausea and vomiting, medication will be administered both during and after the procedure. These symptoms are completely normal and are due to the chemotherapy drugs.
It should be noted that the presence of these symptoms and complications after chemoembolization is normal.
However, in the event of sudden changes, high fever, chills, or uncontrollable pain, be sure to inform your treating physician immediately.
Post-Operative Hospitalization
This procedure is typically performed on an outpatient basis, and the patient is discharged 3 to 4 hours afterward.
Hospitalization may be required for up to 24 hours after the procedure, depending on the patient’s condition.
Attention:
Upon discharge, you will be provided with pain relievers, antipyretics, anti-nausea medications, and antibiotics.
The patient will be able to resume normal activities one week after the procedure.
To evaluate the success of the treatment, a CT scan or MRI will be performed at the center one month after the chemoembolization procedure.
The scheduling of subsequent chemoembolization sessions will be determined based on the response to treatment.
Method of Performing Chemoembolization
This procedure is performed under imaging guidance and local anesthesia. Initially, a specialized catheter is inserted into the hepatic artery through the right femoral artery. After conducting an angiography of the hepatic artery and identifying the tumor’s feeding vessels, the catheter is directed into the blood vessels supplying the tumor. Chemotherapy drugs, along with embolizing agents, are then injected into the tumor’s blood supply.

Frequently Asked Questions
What is chemoembolization, and how is it performed?
In this method, chemotherapy drugs, along with blocking particles, are injected into the artery supplying the tumor. This cuts off the tumor’s blood flow and delivers the medication directly to it.
Who are candidates for chemoembolization?
Patients who have non-resectable liver tumors or require adjunctive therapy to shrink the tumor prior to surgery or other treatments are suitable candidates for this approach.
Does this procedure require hospitalization?
The procedure is typically performed on an outpatient basis or with a short overnight stay. The patient is discharged after a general condition assessment and monitoring for any complications.
