Recognition and management of stent malposition in the portal vein during endoscopic retrograde cholangiopancreatography: A case report

Figure 2 Contrast-enhanced computed tomography. A: Contrast-enhanced computed tomography (CT) image showing that a biliary stent had entered the main portal vein; B: Contrast-enhanced CT images of the reconstructed portal vein; C: The single pigtail stent separated from the single flap stent and migrated straight up the spine into the portal vein; D: Repeated portal angiography showed no contrast leakage after placement of the fully covered metal stent in the common bile duct.
