[Gastroduodenal arterial aneurysm and chronic pancreatitis. A case and review of the literature].

A case of pseudoaneurysm of the gastroduodenal artery due to chronic pancreatitis is reported. Pancreatitis causing splanchnic arterial aneurysm is more likely to affect the splenic artery than the gastroduodenal artery. Ten percent of cases of chronic pancreatitis are associated with splanchnic aneurysm. Hemorrhage occurs in 50% of cases. Color Doppler ultrasound is the best diagnostic tool, indicating the need for coeliac arteriography. In our case report, transcatheter embolization was performed with stainless steel coils and the pseudoaneurysm was successfully occluded.
