How program is carried out

During the first visit, the doctor will conduct a clinical examination and go through the results of the available diagnostic tests. After that, you will undergo the necessary additional examination, such as the assessment of liver and kidney function, ultrasound scan, CT scan and MRI. This will allow the doctor to determine which vessels are feeding the tumor and its metastases, as well as determine how well you will tolerate the procedure.

Chemoembolization begins with local anesthesia and catheterization of the femoral artery. The thin catheter is inserted through a few centimeters long incision of the blood vessel. The doctor gradually moves the catheter to the vessel feeding the primary tumor or its metastases. The procedure is carried out under visual control, an angiographic device is used for this. The vascular bed and the position of the catheter in it are displayed on the screen of the angiograph.

When the catheter reaches a suspected artery, a contrast agent is injected through it. Due to the introduction of the contrast agent, the doctor clearly sees the smallest vessels of the tumor and the surrounding healthy tissues on the screen of the angiograph. After that, he injects emboli into the tumor vessels through the same catheter.

Emboli are the spirals or the liquid microspheres. The type of embolus is selected individually, taking into account the diameter of the target vessel. When carrying out chemoembolization, a solution of a chemotherapy drug is additionally injected into the tumor vessel. Due to the subsequent closure of the vessel lumen with an embolus, the chemotherapy drug influences the tumor for a long time. In addition, the drug does not enter the systemic circulation, which allows doctors to use high doses of chemotherapeutic agents without the development of serious side effects. Chemoembolization leads to the destruction of the tumor or slowing down its progression.

After that, the catheter is removed from the artery. The doctor puts a vascular suture on the femoral artery and closes it with a sterile dressing. During chemoembolization, you will be awake. General anesthesia is not used, which significantly reduces the risks of the procedure and allows performing it on an outpatient basis, avoiding long hospital stay.

After the first procedure, you will stay under the supervision of an interventional oncologist and general practitioner. If necessary, you will receive symptomatic treatment. As a rule, a second chemoembolization procedure is performed in 3-5 days after the first one in order to consolidate the therapeutic effect. After that, you will receive recommendations for further follow-up and treatment.

About the department

The Department of Adult and Pediatric Diagnostic Radiology, Interventional Radiology and Neuroradiology at the University Hospital Duesseldorf offers the full range of modern radiological examinations and minimally invasive imaging-guided treatment of various diseases. Most often, radiologists have to deal with the diagnostics and therapy of tumors, inflammatory processes, injuries, pathologies of the heart and vascular diseases. The combination of advanced medical technologies and high professionalism of the doctors working in the department are the key to the successful treatment results.The department is headed by Prof. Dr. med. Gerald Antoch.

The department is an academic medical institution, therefore, a certain part of its time is devotes to research activities, which give excellent results of international importance.
