Transarterial embolization is a minimally invasive cancer treatment that uses tiny particles to block blood flow to a tumor, causing it to shrink. Our interventional radiologists perform embolization procedures to treat malignant (cancerous) and benign (noncancerous) tumors.
We use embolization to treat tumors that are too big for ablation therapy or that can’t be removed with surgery.
The liver’s blood supply runs through the portal vein and the hepatic artery (which provides the blood that feeds liver tumors). By blocking only the hepatic artery through transarterial embolization, we can starve the cancer cells and stop the growth of the tumor while preserving blood flow to the rest of the liver.
We perform four types of transarterial embolization:
