Successful Balloon-Assisted Hepatic Tract Embolization Using the Pull-Through Technique to Remove a Malpositioned...

Intra-abdominal injury is an uncommon complication of chest tube insertion. A 66-year-old man had empyema and underwent chest tube insertion for drainage. Massive hemorrhage occurred; the postprocedural radiograph showed the malpositioned chest tube in the mediastinum. Computed tomography scan showed that the tube's tip penetrated through the liver capsule and passed through the hepatic vein to the right ventricle. Hepatic tract embolization with coiling was performed during chest tube removal under a controlled condition with the hepatic tract occluded by a balloon catheter. The balloon catheter was placed from the right jugular vein using the pull-through technique, establishing a through-and-through guidewire. This is the first report of successful removal of a chest tube malpositioned in the hepatic vein by balloon-assisted hepatic tract embolization without complication.
