The procedure is typically performed by an interventional radiologist. The patient is usually given local anesthesia and sedation. A small incision is made, usually in the groin area, to insert a catheter into the femoral artery. Using imaging guidance, the catheter is navigated to the blood vessels supplying the area of interest. Once in place, embolic agents such as tiny particles, coils, or foam are injected to block the blood flow.
