Mesenteric Angiography •Commonly performed in patients with signs of lower gastrointestinal bleeding such as melena •Often preceded by a non-invasive nuclear medicine tagged red blood cell scan to confirm active bleeding •Allows diagnosis and immediate intervention through the use of intravascular embolic agents
  3. 3. Mesenteric Angiography •Access the arterial system via the right common femoral artery •Catheter is advanced through the common femoral, external iliac, common iliac, into the aorta •Tip of the catheter placed into the celiac trunk, superior mesenteric artery, and inferior mesenteric artery for contrast injection to search for bleeding
