Bronchial Catheterization with a TIPS Dilator After Failure of Conventional Technique

OBJECTIVE. A technique is presented for catheterization of an obstructed bronchus when use of a conventional vascular catheter has failed. In some cases, strictures become too stenotic or blunt for passage of a guidewire, making further intervention impossible. We attempted to negotiate a stricture opening using a transjugular intrahepatic portosystemic shunt (TIPS) dilator with a guidewire inside it.

CONCLUSION. The catheterization technique with a TIPS dilator was successful in nine cases in which use of conventional catheters and guidewires had failed.
