Non-variceal gastrointestinal bleeding is the significant emergency problem to manage in the hospital. Transcatheter arterial embolization is minimally invasive treatment, which becomes an essential role in controlling bleeding, leading to lifesaving. To reach the goal, the interventional radiologist should have fundamental of vascular anatomy and choice of embolic material, which is the key to success.
