Abstract
Background
Pancreatic arteriovenous malformation is very rare, but may cause significant clinical symptoms such as catastrophic bleeding. Herein, we discuss the clinical presentation and management of patients pancreatic arteriovenous malformations.
Methods
The data pool for the analysis was collected from pancreatic arteriovenous malformation cases encountered by our institution and sporadic case reports in the English literature.
Results
A total of 89 cases of pancreatic arteriovenous malformation were collected for this study, including 59 cases of arteriovenous malformation in the pancreatic head (62.3 %) and 30 in the pancreatic body-tail (33.7 %). The most commonly associated complications for overall cases of pancreatic arteriovenous malformation were bleeding (50.6 %), pancreatitis (16.9 %), portal hypertension (6.7 %), and pseudocyst (3.4 %). The most common presenting symptom of pancreatic arteriovenous malformation was gastrointestinal bleeding (47.2 %), followed by epigastric pain (46.1 %). Surgery (43.8 %) was the most common treatment for pancreatic arteriovenous malformation cases, followed by transarterial embolization (11.2 %), a combination of surgery and transarterial embolization (10.1 %), and radiotherapy (2.2 %). No intervention was done for 29.2 % of the cases of pancreatic arteriovenous malformation.
Conclusions
Pancreatic arteriovenous malformation occurs most commonly in the pancreatic head; gastrointestinal bleeding is the main symptom. Surgical resection or transarterial embolization appears to be indicated in patients with symptomatic pancreatic arteriovenous malformation.
