Acute Ischemic Pancreatitis and Total Splenic Infarction after Coil Embolization of Celiac Artery Aneurysm and Thoracic Endovascular Aortic Aneurysm Repair: A Case Report.

A 75-year-old man with a history of open surgical repair for a thoracoabdominal aortic aneurysm presented with an aortic pseudoaneurysm at the anastomosis and a celiac artery aneurysm. During endovascular treatment, multiple celiac artery branches were embolized, and an aortic stent graft was placed to cover the aortic anastomosis and celiac artery origin. Four days post-treatment, a computed tomography scan revealed poor enhancement and fluid collection in the pancreatic body and tail, indicating acute ischemic pancreatitis with pancreatic necrosis. Computed tomography 22 days after treatment indicated enlargement of the fluid collection, leading to endoscopic ultrasound-guided drainage of the collection. Despite the low risk of ischemic complications, recognizing the risk of ischemic pancreatitis and splenic infarction when multiple celiac artery branches are embolized to treat celiac artery aneurysms is crucial.
