1) Discuss ethiology of GI bleeding and indications for embolization. 2) Describe the vascular anatomy and its variants. 3) Discuss the occult bleeding and role of imaging. 4) Review the results and complications of embolization.
GI bleeding is a frequent clinical problem that is managed in the majority of cases with medical and or endoscopic treatments. The role of embolization has significantly increased in recent years with refinement of the catheters, materials and imaging techniques. However, there is still no general agreement on the exact timing of when to refer patient for endovascular treatments. The knowledge of vascular anatomy and its variants is essential for embolization of the GI bleeding. One of the issues related to the imaging of GI bleeding is its intermittent characteristic. The imaging limitations and benefits as well as the results of embolization in upper and lower GI bleeding will be discussed.
