Successful CT-Guided Thrombin Injection of a Peripancreatic Left Gastric Artery Pseudoaneurysm in Chronic Pancreatitis.

Visceral artery pseudoaneurysms are rare but serious complications of pancreatitis that can be challenging to manage when conventional endovascular approaches are not feasible. We describe the case of a 65-year-old man with chronic pancreatitis who developed a small visceral pseudoaneurysm that could not be safely accessed for embolization because of challenging vascular anatomy. A minimally invasive CT-guided percutaneous thrombin injection was performed, resulting in successful thrombosis and resolution on follow-up imaging. This case highlights an alternative treatment strategy in technically difficult scenarios and underscores the importance of imaging in both diagnosis and postprocedural assessment.
