The arterial malformation, also called an AVM, start to bleed. In some patients this may be a cause of unexplained bleeding and iron deficiency anemia. Often times at endoscopy, such lesions can be missed, since they may not present themselves to be seen by the endoscopist. |

In this picture, the ARGON laser tip has been directed via the endoscope and fired at the AVM. |

After several shots at the AVM, no further bleeding is
noted.
