The Teaching Point

Interventional embolization is able to successfully occlude a giant pseudoaneurym (defined as pseudoaneurysms equal, or greater than, 5 cm in size) of the gastroduodenal artery secondary to chronic pancreatitis even with a wide neck and the origin being in close proximity to the branch-off from the right hepatic artery. At first, one should occlude the GDA distal to the entry of the pseudoaneurysm to stop the backflow. Then one can occlude the pseudoaneurym. Finally, coils can be partially placed inside the GDA to close the entry and to control the risk of massive intraabdominal bleeding. Complete occlusion of the pseudoaneurysm can be achieved without surgery.

Abstract
We report a case of an uncommon giant pseudoaneurysm of the gastroduodenal artery secondary to chronic pancreatitis. It presented with a perfused volume of 17.3 cm³ close to the branch-off of the right hepatic artery. Superselective transcatheter embolization including interlocking detachable coils and a mixture of Ethibloc and Lipiodol was our technique of choice. Following the procedure, the patient was in hemodynamically stable condition. At that time, he was free of any clinical symptoms and showed no further signs of bleeding or ischaemia. Additionally, we present an overview of the relevant literature.
