Embolization is a medical procedure used to block blood vessels to stop bleeding or to cut off blood supply to a tumor. This is done by injecting materials, such as tiny particles or coils, into the blood vessels through a catheter. The goal is to prevent blood flow to specific areas, which can help treat conditions like uterine fibroids or varicose veins. The procedure is minimally invasive and often performed under local anesthesia. It is guided by imaging techniques like X-rays or ultrasound to ensure accuracy. Recovery time is usually short, and patients can often return to normal activities quickly after the procedure.
