Haemosuccus Pancreaticus: Treatment by Arterial Embolization

AIM: Haemosuccus pancreaticus is bleeding into the pancreatic duct from a peripancreatic artery. This condition most commonly follows pseudoaneurysm formation secondary to acute or chronic pancreatitis. It is a rare disorder, challenging in both diagnosis and therapy. We present an eight-year experience of managing these patients using endovascular embolization as the primary therapy. MATERIALS AND METHODS: We retrospectively reviewed the imaging, laboratory results and clinical notes of the five patients who presented to this institution between 1991–1999 with gastrointestinal bleeding subsequently found to be haemosuccus pancreaticus. RESULTS: There were four men and one women aged 38–75 years. All had a history of gastrointestinal haemorrhage and had acute (n = 1) or chronic pancreatitis with a complicating pseudoaneurysm. All underwent embolization as the primary therapy for the pseudoaneurysm. There was immediate technical success in all cases without major complication. No patient required operative surgery for the pseudoaneurysm. Follow-up ranged from 18 months to 7 years. One patient died four years after embolization due to hepatic failure but the other four remain well without further gastrointestinal bleeding. CONCLUSION: Endovascular embolization is an effective and safe treatment for haemosuccus pancreaticus. Dasgupta, R. et al. (2002). Clinical Radiology57, 1021–1027.
