Bad Connection: Stent-to-Stent Fistulization After Common Bile Duct and Transjugular Intrahepatic Portosystemic Shunt Stenting.

A 29-year-old man with chronic portal venous thrombosis resulting in portal biliopathy required stenting of his common bile duct (CBD) and underwent a transjugular intrahepatic portosystemic shunt (TIPS) procedure to decrease portal pressures. He later presented with abdominal pain in the setting of prolonged CBD stent placement and was found to have air within his TIPS stent with a fistula on endoscopic retrograde cholangiopancreatography between his fully covered CBD stent and bare metal TIPS stent. There was concern that further intervention would lead to an air embolus. We suggest that when multiple stents are indicated, stent selection with close monitoring is critical.
