Embolization is a minimally invasive medical procedure used to block or reduce blood flow to a particular area of the body, typically to treat conditions such as aneurysms, tumors, or abnormal blood vessels. This is achieved by inserting a catheter into a blood vessel and deploying tiny particles, coils, or other devices to block the flow of blood to the targeted area. Embolization can help reduce the size of tumors, prevent hemorrhaging, or relieve symptoms associated with certain conditions. It is often performed by interventional radiologists and has been shown to be a safe and effective alternative to surgery in many cases.
