Abstract
Pancreatic arteriovenous malformation is a rare vascular anomaly which may cause abdominal pain, acute pancreatitis, gastrointestinal bleeding and portal hypertension. Pancreatic arteriovenous malformation is mostly congenital; however secondary pancreatic arteriovenous malformation due to pancreatitis has been suggested by some authors. We encountered a case which can confirm this presumption. Several imaging modalities are useful for the diagnosis of pancreatic arteriovenous malformation, especially dynamic contrast-enhanced studies. Angiography is the most important diagnostic tool because of the dynamic features of this vascular lesion. Treatment is advised and consists of surgical resection and/or transarterial embolization.
Highlights
Pancreatic arteriovenous malformation is a rare vascular anomaly which may cause abdominal pain, acute pancreatitis, gastrointestinal bleeding and portal hypertension
Pancreatic arteriovenous malformation (AVM) is a vascular anomaly with an abnormal anastomosis of the arterial and portal network and was first described by Halpern et al in 1968 [9]
But they may be complicated with gastrointestinal bleeding, portal hypertension and abdominal pain [10]
Summary
Pancreatic arteriovenous malformation is a rare vascular anomaly which may cause abdominal pain, acute pancreatitis, gastrointestinal bleeding and portal hypertension. Pancreatic arteriovenous malformation (AVM) is a rare, mostly congenital, vascular anomaly. Several case reports have described pancreatic AVM as a cause for focal pancreatitis [4,5,6]. Some authors have suggested that pancreatitis may be complicated with the formation of a pancreatic AVM [7, 8].
