Transcatheter arterial embolization of a type 2 endoleak through the dorsal pancreatic artery after the hybrid repair of a thoracoabdominal aortic aneurysm: A case report.

An 83-year-old woman with a history of hybrid repair of thoracoabdominal aortic aneurysm presented with enlargement of the aneurysm due to a type 2 endoleak from the celiac artery. The endoleak cavity was accessed via the dorsal pancreatic artery, and embolization using N-butyl cyanoacrylate and coils was successfully performed. When celiac artery branches are embolized during hybrid repair of a thoracoabdominal aortic aneurysm, attention should be paid to the dorsal pancreatic artery to appropriately determine which branches are to be embolized, because a nonembolized dorsal pancreatic artery may lead to type 2 endoleaks.
