[A case of relapsed hemosuccus pancreaticus successfully treated with interventional radiology].

A 67-year-old male with chronic pancreatitis presented with upper abdominal pain and melena. Abdominal dynamic computed tomography revealed a splenic artery aneurysm in the main pancreatic duct. Esophagogastroduodenoscopy showed active bleeding from Vater's papilla. The patient was diagnosed with hemosuccus pancreaticus (HP) due to rupture of the aneurysm and treated with interventional radiology (IVR). The patient's poor lung function did not allow for a radical operation and a follow-up examination was recommended. The HP relapsed 7 months later and was successfully retreated with IVR. Although IVR is associated with a high recurrence rate, it is less invasive and therefore effective for treating relapsing HP in patients with a poor general condition.
