ABSTRACT

Introduction The continuous development and improvement of materials and techniques in recent years has led to a wide spectrum of methods for transcatheter occlusive therapy. Since the 1970s the percutaneous treatment of multiple and varied pathologies with detachable balloons, big particles, and rudimentary coils has been introduced.1-3 Advances in agents for embolization and in catheter and guidewire technology have increased the reach of the interventional radiologist in treating a variety of pathologic conditions that were traditionally treated by surgery. The proper use of embolization techniques requires an understanding of the vascular anatomy and pathology, the tools used to deliver embolic agents, and the embolic agents themselves.
