Tube Tamponade: Potential Pitfall in Angiography of Arterial Hemorrhage Associated with Percutaneous Drainage Catheters

Abstract

Diagnostic angiography performed to search for a source of hemorrhage in three patients with percutaneous transhepatic biliary catheters and one patient with a percutaneous nephrostomy catheter was initially unrewarding when performed with the drainage catheter in place. In each patient, removal of the drainage catheter resulted in severe pulsatile hemorrhage from the parenchymal tract and allowed angiographic localization of the bleeding site. Temporary control of the hemorrhage was then obtained by inflating an angioplasty balloon within the tract. Transcatheter embolotherapy provided definitive control of bleeding in three patients. When initial angiographic evaluation for bleeding in patients with percutaneous biliary and nephrostomy catheters fails to depict a source, the study should be repeated immediately after removal of the drainage catheter. Because hemorrhage can be severe once tamponade is relieved, the drainage catheter should be withdrawn over a guide wire so that a tamponading catheter can be rapidly reinserted to control hemorrhage until more definitive therapy is undertaken.
