Abstract
This paper describes two cases of gastroduodenal artery aneurysms (GDAA), with a review of literature in Japan, in order to make some notes of the changes in pathologic concepts, etiology, and the diagnosis of GDAA.
Genrally, aneurysms of the branches of ceriac axis are quiet in symptom, but they have a high probability of rupture, leading to a fatal outcome. It is necessary to confirm a definite diagnosis, and surgical ligation or resection. Diagnosis by ultrasonography and dynamic CT scan is useful.
