Tumor embolization is a procedure in which medical material (embolization) is injected into a vessel feeding a tumor in order to block blood flow and reduce its size or even completely destroy it. This is one of the methods of treating tumors, especially in cases where surgical removal of the tumor is impossible or involves high risks.
The procedure for tumor embolization usually includes the following steps::
- Diagnosis: Before tumor embolization, the patient may be assigned a number of examinations, such as computed tomography (CT), magnetic resonance imaging (MRI), or angiography to accurately determine the location and characteristics of the tumor.
- Preparation: The patient may be pre-prepared, including discontinuation of certain medications and restriction of food intake before the procedure.
- Procedure: During the procedure, a catheter is inserted into a vessel feeding the tumor, under the supervision of X-ray equipment. Then an embolus (usually special particles or liquid) is inserted through a catheter to block blood flow to the tumor.
- Monitoring and observation: After the procedure, the patient may remain under observation for some time to monitor the condition and effectiveness of embolization.
Tumor embolization can be used to treat various types of tumors, including tumors of the liver, kidneys, brain, and other organs. This method can help reduce the size of the tumor, reduce its blood flow, and prepare the patient for subsequent surgery or radiotherapy. Like any medical procedure, tumor embolization has its risks and benefits, and the decision to perform it should be made after careful discussion with a medical professional.
