Summary:A 49-year-old man was diagnosed with severe acute pancreatitis because of pancreatic arteriovenous malformation (AVM). The pancreatic AVM spontaneously regressed during conservative treatment for severe acute pancreatitis. Transarterial embolization of an aneurysm in an artery branch flowing into the pancreatic AVM was performed using metallic coils, following amelioration of severe acute pancreatitis. The complete elimination of the pancreatic AVM was confirmed 1 year after embolization, and the patient has had no recurrence of pancreatic AVM and pancreatitis for over 6 years. Most cases of pancreatic AVMs with acute pancreatitis require surgical resection. This is a rare case in which the pancreatic AVM spontaneously regressed under the influence of acute severe pancreatitis.
