Arterial embolization is a procedure used to selectively block blood flow to areas of the body, such as tumors, arteriovenous malformations, or bleeding vessels. During the procedure, embolic agents are injected through a catheter into the affected artery, causing the blood flow to stop and preventing further bleeding or tumor growth.

Arterial embolization is commonly used in the treatment of certain cancers, gastrointestinal bleeding, or in trauma cases to control bleeding, offering a less invasive alternative to surgery.
