Preoperative Embolization of Tumors


Our physicians use state-of-the-art technology in their fight against cancer. We evaluate every cancer patient and find the most appropriate treatment plan possible, one that offers the best chances for a cure. Using the most advanced interventional radiology (IR) procedures and imaging modalities we treat tumors directly, and avoid many of the drawbacks of more systemic treatments.

About the procedure

Preoperative embolization is a procedure where blood flow to a tumor is reduced before it is surgically removed. This is accomplished by injecting a clotting material into the artery which blocks the supply of blood to the tumor (embolization). The procedure is usually performed a few days prior to surgery.

Why it’s done

Tumors that occur in the kidneys, liver, and bones may have a large blood supply, making their removal during surgery both difficult and risky. Preoperative embolization has proven to lower intraoperative blood loss and the need for transfusions. The procedure can also reduce the overall amount of time required to complete the surgery. Once the tumor no longer receives nutrients and oxygen to feed it, the size is greatly reduced.

What to expect

Preparation: Preoperative embolization is usually performed several days prior to surgery, but it may be used as a stand-alone treatment. Your CIC physician will tell you what medications to take and when to stop taking those that put you at a higher risk of complications. Don’t eat or drink anything after midnight the night before the procedure.

During: Once you arrive at your appointment, you will change into a patient gown. You will be given an IV with medication that makes you feel more relaxed. Your CiC physician will gain access to your arterial blood system either through the radial artery in your wrist or the large artery in your groin. The site will be prepped, draped, and anesthetized. Using guidance, a small catheter will be guided into the artery supplying the tumor. Once the catheter is in place, the embolization material is injected into the tumor.

After: You may feel groggy and tired after the procedure. Bring someone with you to drive you home.
