title: Percutaneous thrombin embolization of a ruptured peripancreatic pseudoaneurysm.
abstract: Peripancreatic pseudoaneurysm formation is a recognized complication of pancreatitis. When associated with an acute episode of pancreatitis, surgical treatment is often difficult due to the inflammatory process that surrounds the pseudoaneurysm. In the stable patient, transcatheter embolization is the treatment of choice of this complication. However, this is not always technically feasible, as the aneurysm may be supplied by small inaccessible branch vessels. Recently, percutaneous thrombin injection has been described as a possible alternative for pseudoaneurysms. This is generally performed under computed tomography guidance in stable patients with non-ruptured pseudoaneurysms. We describe an acutely ruptured peripancreatic pseudoaneurysm in a critically ill patient, in whom percutaneous thrombin injection under computed tomography guidance resulted in immediate stabilization and cure of the pseudoaneurysm.
