[Pseudoaneurysm of the gastroduodenal artery: clinical case]

The Author report a case of massive digestive hemorrhage from fistulization into the duodenum of a pseudoaneurysm of the gastroduodenal artery consequent upon pancreatic pseudocyst. The surgical treatment consisted in intracyst artery ligation and led to complete reabsorption of the pseudocyst formation and healing of the patient. Bleeding from pseudoaneurysm has a high mortality rate and requires a surgery that may be very difficult to perform in emergency conditions. In this type of surgery it's important an anterior approach of pancreas, to do a good preoperatory diagnosis, and a good knowledge of surgical anatomy.
