Pancreatic arteriovenous malformation treated with transcatheter arterial embolization: Two case reports and review of literature

Abstract

BACKGROUND

Various treatment methods are available for the treatment of pancreatic arteriovenous malformation (P-AVM); however, there are no established treatment options for asymptomatic P-AVM.

CASE SUMMARY

A 47-year-old and a 50-year-old male patients sought treatment for P-AVM in the pancreas, which was incidentally detected during routine abdominal computed tomography and magnetic resonance imaging conducted as part of a health check-up. They underwent transcatheter arterial embolization (TAE), and over the course of a 9-year follow-up period, the AVM did not worsen and was asymptomatic.

CONCLUSION

TAE can be considered as an alternative treatment option for P-AVM in selective cases where patients are asymptomatic or have a high surgical risk.

Core Tip: Pancreatic arteriovenous malformation (P-AVM) is a rare condition characterized by symptoms like gastrointestinal bleeding and abdominal pain, with some cases being asymptomatic. Surgical intervention is commonly considered for symptomatic cases, but the treatment of asymptomatic P-AVMs is not well-established. Previous studies have reported various methods, including surgery and transcatheter arterial embolization (TAE). In selective cases, particularly for asymptomatic or high surgical risk patients, TAE may be an effective and safe treatment option.
