Principle of Transcatheter Vascular Embolotherapy

Abstract

Transcatheter vascular embolotherapy is a part of interventional radiology procedure which defined as the percutaneous endovascular use of agents or materials to accomplish target vascular occlusion. Its applications continue to expand and have become an integral component of the multimodality management paradigms in many emergency setting, such as trauma, massive bleeding from various causes. Therapeutic embolization also has a major role in many elective scenarios, particularly in modern oncologic center such as performed following transarterial infusion of chemotherapeutic drugs for treatment of hepatic tumors (known as chemoembolization). The approach to each clinical scenarios are different, including the choice of embolic agents and potential risks or complication of embolization. Improvement of therapeutic outcomes and complication preventive strategy can be achieved with good knowledge of principles of embolization, proper patient selection and good technical skill.
