Malformación arteriovenosa pancreática como causa de pancreatitis aguda tratada por vía endovascular / Pancreatic arteriovenous malformation as cause of acute pancreatitis treated by endovascular access

La malformación arterio-venosa (MAV) en el páncreas es una anomalía anatómica poco frecuente que puede ser causa de pancreatitis aguda. Presentamos el caso de un paciente de 46 años cuyo diagnóstico se sospechó por los hallazgos de la tomografía computarizada con contraste endovenoso y por resonancia magnética y se confirmó mediante una arteriografía del tronco celíaco y de la arteria mesentérica superior. El tratamiento recibido fue por vía endovascular, aunque la otra opción válida para el tratamiento de esta enfermedad es la resección quirúrgica. El objetivo de esta comunicación es presentar un caso de pancreatitis aguda por MAV tratada por vía endovascular.

Arteriovenous malformation in the pancreas is a rare anatomic abnormality that may produce acute pancreatitis. The diagnosis was suspected by computed tomography with intravenous contrast and by magnetic resonance imaging and it was confirmed by arteriography of the celiac trunk and superior mesenteric artery. The treatment received was endovascular, although the other valid option for the treatment of this disease is the surgical resection. The objective of this communication is to present a case of acute pancreatitis due to arteriovenous malformation treated by endovascular approach.

A Case of Recurrent Infection Caused by a Pancreaticoduodenal Fistula Associated with a Pancreatic Arteriovenous Malformation

Although arteriovenous malformations (AVM) occur frequently in digestive organs, pancreatic AVM is rare. The clinical symptoms of pancreatic AVM are variable and include gastrointestinal bleeding, abdominal pain, jaundice, portal hypertension, pancreatitis, and duodenal ulcer. However, choledochoduodenal or pancreaticoduodenal fistulas complicated with ascending infection and pancreatitis is extremely rare. Herein, we report a case of pancreaticoduodenal fistula associated with a pancreatic AVM that induced recurrent anemia and ascending infection.

A Case of Recurrent Acute Pancreatitis due to Pancreatic Arteriovenous Malformation

Pancreatic arteriovenous malformation (AVM) is an extremely rare condition with various clinical manifestations. We report herein a case of recurrent acute pancreatitis due to pancreatic AVM in a 49-year-old man. This patient presented with epigastric pain that had developed after consuming alcohol 2 days prior to admission. Serum amylase and lipase levels were elevated and computed tomography revealed focal low-attenuation lesions with peripancreatic infiltrations in the pancreatic tail and multiple collateral vessels around the low-attenuation lesions. He was diagnosed with acute pancreatitis and pancreatic AVM. Although he had stopped drinking after the first attack of acute pancreatitis, his pancreatitis recurred twice within 3 months. He underwent a distal pancreatectomy after the third attack of acute pancreatitis. He was free of symptoms for 2 years after the pancreatectomy.

A Case of Duodenal Ulcer Bleeding caused by Pancreatic Arteriovenous Malformation / 대한소화기내시경학회지

Arteriovenous malformation (AVM) of the pancreas is an extremely rare disease. It may be asymptomatic, but more than half of the patients present with gastrointestinal bleeding. The most common cause of the gastrointestinal bleeding is variceal bleeding due to the portal hypertension resulting from AVM. Bleeding from a duodenal ulcer and AVM to the pancreatic duct are rare findings. Surgical excision is the treatment of choice, but when portal hypertension has developed, this cannot be corrected even after surgical resection. We experienced a case of recurrent duodenal ulcer bleeding that was due to arteriovenous malformation in the head of the pancreas in a 45 year old man. He was successfully treated with pylorus preserving pancreaticoduodenectomy.
