摘要
Pancreatoduodenectomy can be difficult in patients with obstruction of the celiac axis because of the development of collateral arteries around the head of the pancreas. Bleeding from a pseudoaneurysm is a rare and serious complication of pancreatoduodenectomy. We report a case of a pseudoaneurysm of an enlarged dorsal pancreatic artery, which formed as a result of obstruciton of the celiac axis after pancreatoduodenectomy. We assumed that a weakness in the wall of this dorsal pancreatic artery caused by the dissection led to the formation of the aneurysm. Although transcatheter arterial embolization (TAE) could not treat the aneurysm or stop bleeding from the aneurysm completely, it achieved transient hemostasis, whereby the patients condition improved, making laparotomy safe. This case demonstrates that the dissection of arteries that have developed around the head of the pancreas must be considered in patients with obstruction of the celiac axis.
